SUMMARY:Integrated Sensing and Communications: From Signal Processing to Prototype
DESCRIPTION:Abstract\nIntegrating sensing functionality into communication devices is emerging as a key feature of the 6G Radio access network. Dual-function radar communication (DFRC) systems implement both sensing and communication using the same hardware thus saving in power\, cost and spectral efficiency. In this talk\, we focus on some of the signal processing aspects of designing and implementing DFRC systems and discuss how the convergence of sensing and communication can be utilized to efficiently exploit congested resources and to communicatee intelligence via sensing.  In particular\, we begin by introducing several approaches to reduce hardware cost by exploiting sub-Nyquist principles and sparse arrays to sense and communicate jointly at low sampling and bit rates. We then introduce new hardware designs that allow continuous monitoring using event-based sampling and high dynamic range. We next consider several different approaches to waveform design and receive signal processing considering both radar detection mode and target localization including spectrum sharing\, joint precoder design\, and index modulation techniques. Our approaches allow design flexibility in trading off radar and communication performance\, while preserving the radar ambiguity function. We end by discussing future trends in DFRC systems including model-based AI for communication and radar under uncertain channels\, near-field communication and radar\, and hybrid RIS/DMA to create configurable radiation patterns for scalable and low power sensing and communication. Throughout the talk we will consider both the theory and hardware prototypes and show several demos of real-time DFRC systems\, low bit and low power ADCs\, and cognitive joint radio and radar systems. \nSpeaker\nProf. Yonina Eldar\nWeizmann Institute of Science\, Israel \nBiography of the Speaker\nYonina Eldar is a Professor in the Department of Mathematics and Computer Science\, Weizmann Institute of Science\, Rehovot\, Israel where she heads the Center for Biomedical Engineering and Signal Processing and holds the Dorothy and Patrick Gorman Professorial Chair.

SUMMARY:Data-Centric Architecture and Algorithm Co-design for Data-Intensive Modern Applications
DESCRIPTION:Mode: Online via Zoom\nZoom Link: https://hku.zoom.us/j/97278710788?pwd=VOGfxnayhDjXu3PTxj37IfWDzCGQ1i.1\nMeeting ID: 972 7871 0788\nPassword: 533887 \nAbstract\nIn today’s digital landscape\, the exponential growth of data has become the driving force behind modern applications\, such as genome analysis and machine learning applications\, revolutionizing our approach to healthcare and overall living quality. However\, this unprecedented deluge of data poses a formidable challenge to traditional von Neumann computer architectures. The inefficiencies arising from the constant data movement between processors and memory consume a substantial portion of both execution time and energy when running modern applications on conventional von Neumann computers. To reduce this significant data movement\, data-centric architectures\, particularly processing-in-memory accelerators\, emerge as a promising solution by enabling the processing of data directly where it resides. Nonetheless\, most existing data-centric architectures primarily focus on accelerating specific arithmetic operations\, inadvertently leaving a substantial gap between the architectural enhancements and the holistic needs of modern applications. Concurrently\, conventional software optimizations often treat the architecture as a black box\, which inherently limits the potential acceleration of applications. \nThis talk seeks to bridge the gaps between modern applications and data-centric architectures and revolutionize the landscape of data-centric acceleration. First\, this talk delves into the distinctive features of modern applications\, illustrating these features with a focus on genome analysis within the realm of bioinformatics. Second\, challenges arise when data-intensive modern applications are executed on conventional computers. The talk then transitions to a compelling remedy: the adoption of a data-centric architecture. Third\, this talk outlines the intricacies involved in designing a data-centric architecture for modern applications. It explores the challenges inherent in this process and concurrently offers potential solutions. Following this analysis\, the talk advances to put forth an innovative architecture specifically designed for genome analysis via algorithm-architecture co-design. In conclusion\, the talk wraps up with a summary and a glimpse into future avenues of exploration. \nSpeaker\nDr. Haiyu Mao\nLecturer (Assistant Professor)\,\nDepartment of Engineering\,\nKing’s College London \nBiography of the Speaker\nDr. Haiyu Mao is a Lecturer (Assistant Professor) in the Department of Engineering at King’s College London. Before that\, she was a postdoctoral researcher in the SAFARI Research group led by Prof. Onur Mutlu at ETH Zurich\, Switzerland\, since September 2020. In July 2020\, she received her Ph.D. degree in computer science from Tsinghua University\, China.

SUMMARY:Low-coherence Biophotonics Imaging for the Brain
DESCRIPTION:Abstract\nThis talk will highlight our recent efforts to explore the brain using low-coherence light. We will discuss two key scenarios: intraoperative assessment of brain cancer infiltration in patients and real-time imaging of dynamic neural activities in freely behaving rodents. In the first scenario\, focused on clinical translation\, we developed a quantitative color-coded optical coherence tomography (OCT) technology. This provides neurosurgeons with direct visual cues based on the intrinsic optical properties of tissues\, enabling them to maximize cancer resection while minimizing damage to healthy brain tissue. Our results from over 50 patients demonstrate excellent specificity and sensitivity. For the second scenario\, which pertains to basic research\, we created the first all-fiber-optic\, head-mounted\, ultracompact (~2 mm diameter)\, and ultralight (<1 g) two-photon fiberscopy platform. This allows for high-resolution imaging of neuronal activity in freely walking or rotating mice. We will discuss recent advancements\, including a 15X increase in the area field of view through cascaded magnification\, facilitating the imaging of multiple neurons and their functional correlations within a single frame. Additionally\, we achieved a significant increase in imaging frame rates (10-30 times faster\, reaching video rates) through an improved scanner design and a two-stage deep learning strategy. Detailed neural imaging results will be presented at the seminar\, and if time permits\, we will also explore other applications of these technologies for noninvasive in vivo optical histology. \nSpeaker\nProf. Xingde Li\nDepartment of Biomedical Engineering\,\nJohns Hopkins University \nBiography of the Speaker\nXingde Li earned his PhD in Physics from the University of PENN in 1998. Following 3 years of postdoctoral training at MIT\, he began his academic career as Assistant Professor at the University of Washington. In 2009\, he joined the BME Department at Johns Hopkins as Associate Professor and later became a Full Professor in 2011.

SUMMARY:Towards Provable Unaligned Multimodal Learning: A Model Identification Perspective
DESCRIPTION:The seminar scheduled for November 19\, 2024 (Tue) will start earlier at 1:30 pm\, while the date and venue will remain unchanged.\nAbstract\n2023 was “the year of AI”\, highlighted by the release of numerous AI models with remarkable capabilities. Multimodal learning is at the forefront of AI advancements\, with state-of-the-art models like GPT-4 and Gemini emphasizing multimodal functionalities as their defining features. Despite its importance\, many aspects of multimodal learning\, and AI developments in general\, still lack a concrete and comprehensive understanding—which is essential for building resilient and trustworthy systems. Our research focuses on the understanding of AI/ML systems to drive theory-backed advancements. From this perspective\, this presentation revisits a core component of multimodal learning—Unsupervised Domain Translation (UDT). Many UDT systems\, such as CycleGAN\, use Distribution Matching (DM) modules\, which often fail in content-aligned translations due to measure-preserving automorphism (MPA). Existing remedies fall short of guaranteed performance. In my talk\, I will introduce a model identification perspective for UDT\, overcoming the MPA issues and ensuring identifiability of the desired translation functions. This is the first proven identification result in UDT under CycleGAN’s settings\, to our knowledge. We have also broadened these concepts\, providing solutions for various translation challenges\, enabling provable content-style disentanglement\, and offering more versatile cross-domain data generation. These advancements promise significant theoretically supported enhancements for UDT applications\, particularly in annotation-limited fields such as medicine and biology. \nSpeaker\nProf. Xiao Fu\nAssociate Professor\,\nOregon State University \nBiography of the Speaker\nXiao Fu has been with the School of Electrical Engineering and Computer Science\, Oregon State University since 2017\, where he is currently an Associate Professor. He received the Ph.D. degree in Electronic Engineering from The Chinese University of Hong Kong\, in 2014. He was a Postdoctoral Associate with the Department of Electrical and Computer Engineering\, University of Minnesota – Twin Cities\, from 2014 to 2017. His research interests include the broad area of machine learning and signal processing\, especially theory and algorithms. Dr. Fu received the Best Student Paper Award at ICASSP 2014\, the 2022 IEEE Signal Processing Society (SPS) Best Paper Award\, and the 2022 IEEE SPS Donald G. Fink Overview Paper Award. He also received the Outstanding Postdoctoral Scholar Award at University of Minnesota in 2016\, the Engelbrecht Early Career Faculty Award from the College of Engineering at Oregon State University in 2023\, and the National Science Foundation (NSF) CAREER Award in 2022. \nOrganiser\nProf. Kaibin Huang\nHead of Department\,\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nAll are welcome!

SUMMARY:The Sound of Music at the Nanoscale – Exploring the Nanoscale World with NEMS Resonators Based on Low Dimensional Nanomaterials
DESCRIPTION:Abstract\nThe advent of low-dimensional nanostructures has enabled a plethora of new devices and systems. Among them\, nanoelectromechanical systems (NEMS) offers the unique capability of coupling the exquisite material properties found in these atomically-defined nanostructures with their mechanical degree of freedom\, opening new opportunities for exploring exotic phenomena at the nanoscale. In particular\, as these devices driven into mechanical vibration—just as musical instruments—they become essentially nanoscale guitars\, drums\, tuning folks\, etc. By studying the infinitesimal mechanical vibrations in these nanoscale “music instruments”\, i.e.\, listening to the “sound of music” at the nanoscale\, researchers can study a number of fundamental physical processes such as absorption\, phase transition\, anisotropy\, and nonlinear processes. \nSpeaker\nProf. Zenghui Wang\nInstitute of Frontier and Fundamental Sciences\,\nUniversity of Electronic Science and Technology of China \nBiography of the Speaker          \nZenghui Wang is currently a professor in the Institute of Frontier and Fundamental Sciences (IFFS) at the University of Electronic Science and Technology of China (UESTC). His research interests and expertise primarily focus on nanoscale devices and systems\, particularly Nanoscale Resonators\, and High-Frequency Resonant Sensors & Transducers. Prior to joining Case\, during 2010-2012\, he worked at Cornell University as a postdoc researcher. He earned a Ph.D. degree (2010) from University of Washington\, Seattle\, for building an ultra-high frequency NEMS resonant sensor with an individual single-walled carbon nanotube\, and using it to detect and study the low-dimensional phase transitions of the atomic layer adsorbed on the nanotube surface. He is an expert on studies of emerging nanoscale devices and sensors based on new materials such as carbon nanotubes\, graphene\, and other low-dimensional nanomaterials\, and has published 20+ research articles in peer-reviewed journals\, including Science\, Nature Physics\, Nature Nanotechnology\, Nature Communications\, Science Advances\, Nano Letters\, ACS Nano\, Physical Review Letters\, 2D Materials\, etc.\,.

SUMMARY:Collaboration and Evolution of Foundation and Specialized Models
DESCRIPTION:The seminar scheduled for 24 October 2024 (Thur) has been postponed to 7 November 2024 (Thur)\, and time and venue remain unchanged.\n\n \n\nAbstract\nThe prevailing GPU resource monopoly significantly restricts AI development\, confining participation in the pretraining stages of Large Language Models (LLMs) to a few researchers. This project introduces a novel system that integrates hundreds of domain-specific models to construct a foundational model for Artificial General Intelligence (AGI) with minimal computational demand. By employing smaller\, efficient models\, leveraging top-ranked models across diverse domains through a robust ranking algorithm\, and continuously optimizing the evolving foundation model\, this approach seeks to democratize AI development. It shifts from the traditional ‘model over data’ method to a ‘model over models’ strategy\, aiming to reduce reliance on extensive computational resources and promote broader innovation and inclusivity in AI. \nSpeaker\nProf. Hongxia Yang\nProfessor\,\nDepartment of Computing\,\nThe Hong Kong Polytechnic University \nBiography of the Speaker\nProf. Hongxia Yang\, with over 15 years of experience as an AI scientist\, specializes in large-scale machine learning\, data mining\, and deep learning. Throughout her career\, she has developed 10 significant algorithmic systems\, improving the operations of various enterprises. Her research includes pre-trained models\, big data analytics\, and the practical deployment of large language model(LLM) systems in real settings. Prof. Yang has published more than 100 top-tier papers\, amassed around 10K citations with an H-index of 44\, and holds over 50 patents. She has received several awards\, including the 2019 SAIL Award at the World Artificial Intelligence Conference and the 2020 National Science and Technology Progress Award\, China’s top tech accolade. Named one of Forbes China’s Top 50 Women in Tech in 2022 and AI 2000 Most Influential Scholar Award in 2023-2024\, Prof. Yang has held prominent roles at ByteDance US\, Alibaba Group\, Yahoo!

SUMMARY:Felix Wu Distinguished Lecture in Power Systems: Change of Paradigm of Power System Operation and Control
DESCRIPTION:Abstract\nSince the inception at the end of the 19th Century\, technical characteristics of power systems have been determined by the physics of synchronous machines (SMs) that convert the primary energy produced by thermal/hydro/nuclear power stations into electricity. However\, the traditional power plants are increasingly being replaced by wind/PV plants and batteries which are connected to the grid asynchronously by means of power electronics (controllable inverters). This means that the power system technical characteristics are increasingly being determined by the control algorithms of inverters rather than the physics of SMs\, and this has profound consequences for power system operation and control. The presentation will discuss those changes and especially the question to what extent inverters can replace synchronous machines. \nSpeaker\nProf. Janusz Bialek\nPrincipal Research Fellow\,\nImperial College London \nBiography of the Speaker\nProfessor Janusz Bialek (FIEEE) is Principal Research Fellow at Imperial College London. Previously\, he held Chair positions at the University of Edinburgh\, Durham University\, Newcastle University and Skolkovo Institute of Science and Technology (Skoltech). Janusz has been PI and Col of multi-million research grants funded by UK research councils and the industry\, and a consultant to the UK government\, European Commission\, and International Energy Agency. He has published widely on integration of renewable generation in power systems\, smart grids\, power system dynamics\, preventing electricity blackouts and power markets. His current main research interests are in addressing the techno-economic challenges posed by increasing penetration of wind/PV/batteries and other devices that are connected to the grid by means of power electronics (programmable inverters)\, rather than synchronous machines\, therefore changing fundamental technical characteristics of the power system. \nOrganiser\nProf. Y.

SUMMARY:Fundamental Principle of Magnetic Levitation for AI Driven Maglev Rides
DESCRIPTION:  \nSeminar on “Fundamental Principle of Magnetic Levitation for AI Driven Maglev Rides” \nDear Colleagues and Students\, \nYou are cordially invited to join the upcoming seminar on “Fundamental Principle of Magnetic Levitation for AI Driven Maglev Rides”. Please find the details below. \nDate: 4 November 2024 (Monday)\nTime: 11:00 am – 12:00 noon (HKT)\nVenue: Room 603\, 6/F\, Chow Yei Ching Building\, The University of Hong Kong\nZoom: https://hku.zoom.us/j/97401048897?pwd=WS8LiUbmLYOCce4bIWW8nHbHSDrJg0.1\nMeeting ID: 974 0104 8897\nPassword: 980783\n\nSpeaker\nProf. Joseph Y Hui\nArizona State University \nModerators\nProf. Victor O.K. Li & Prof. Jacqueline C.K. Lam\nDirector & Co-director\,\nHKU-Cambridge AI-WiSe \nAbstract\nElectric propulsion was invented by Michael Faraday who laid the foundation of electric locomotion. Subsequent effort for magnetic levitation has failed to replace wheels as the primary means of reducing impedance to locomotion. My thesis is that levitation should start from Ampere’s law:\n\nBased on this first principle\, I invented and patented a method that will make cars obsolete. Personal AI driven maglev is small\, simple\, silent\, smooth\, speedy\, safe\, smart\, and saving time\, energy and the environment with zero carbon emission. I will demonstrate a working maglev hoverboard and vehicle to show you how personal maglev will change the World. We propose building personal maglev for the Northern Metropolis. We can also increase China’s High Speed Rail throughput 10X and decrease cost to passenger 10X using existing rail infrastructures and individualized AI driven maglev carriages to transport passengers end-to-end without fixed train schedule. \nBiography of the Speaker\nJoseph Y Hui matriculated in 1977 and won the IIE scholarship to attend MIT\, where he earned his BS’81\, MS’81\, EE’82\, and PhD’83 degrees\, all in EECS. He has worked at Comsat\, Bell Labs\, Bellcore\, and IBM. He taught at Columbia University (86-89)\, Rutgers University (89-99)\, Chinese University (95-99)\, and ASU (99 – now). He works on his AWESOME inventions for clean Air\, Water\, and Energy as well as fast and safe travel by Space\, Ocean\, Maglev\, and Eviation. He is an IEEE fellow\, NSF Presidential Young Investigator\, and member of US Academy of Inventors with tens of patents granted.\n\nLooking forward to welcoming you at the seminar next Monday. \nBest Regards\,\nVictor O.K.

SUMMARY:Big AI for Small Devices
DESCRIPTION:Abstract\nAs artificial intelligence (AI) transforms industries\, state-of-the-art models have exploded in size and capability. However\, deploying these models on resource-constrained edge devices remains a significant challenge. Smartphones\, wearables\, and IoT sensors face stringent limitations on compute\, memory\, power\, and communication\, creating a gap between demanding AI models and edge hardware capabilities that hinders the deployment of intelligence. In this talk\, we will re-examine techniques to bridge this gap and embed big AI on small devices. We will begin by discussing how the properties of various hardware platforms impact the design strategies of efficient deep neural network (DNN) models\, such as quantization and pruning. Next\, we will discuss techniques aimed at reducing the inference and training costs of distributed collaborative edge AI systems. Finally\, we will delve into the underlying design philosophies and their evolution toward efficient\, scalable\, robust\, and secure edge computing systems. \nSpeaker\nProf. Yiran Chen\nJohn Cocke Distinguished Professor of Electrical and Computer Engineering\,\nDuke University \nBiography of the Speaker\nProf. Yiran Chen is the John Cocke Distinguished Professor of Electrical and Computer Engineering at Duke University.

SUMMARY:Enhancing Contrast\, Field of View and Axial Resolution of Structured Illumination Microscopy
DESCRIPTION:Direction to Innovation Wing Two: https://innowings.engg.hku.hk/innowing2/visitors \nAbstract\nSuper-resolved structured illumination microscopy (SR-SIM) is among the most flexible\, fastest and least perturbing fluorescence microscopy techniques capable of surpassing the optical diffraction limit. Current custom-built instruments are easily able to deliver two-fold resolution enhancement at video-rate frame rates\, but the cost of the instruments is still relatively high and the physical size of the instruments is still prohibitively large. We have developed compact\, cost-efficient and high-speed 2D-\, grazing-incidence- and TIRF-SIM to overcome these limitations. A fiber-based illumination path allows multi-color imaging with a field-of-view (FOV) of up to 230×230 µm². A novel method called multi-angle TIRF SIM allows an image reconstruction with an enhanced axial resolution. The setup consists of a fiber-coupled laser combiner with 405 nm\, 491 nm\, 561 nm and 639 nm laser sources\, a fiber-switch to select the desired illumination angle with integrated phase shifters and a hexagonal fiber collimator with a lens telescope that projects the beams into the back-focal plane of the objective lens. All modules of the illumination path are home-built to achieve highest stability and a compact size. The rotation of the illumination angle is performed by two galvo-mirrors that select the corresponding pair of fibers and phase shifts of the zero order beam and one of the two first order beams are performed by home-built\, MEMS-mirror based phase-shifters that modulate the optical path length. The phase shifters and galvo-mirrors allow transition times between illumination patterns of less than 1 ms. The hexagonal collimator allows to adjust the pattern spacing in the sample seamlessly\, within a transition time of 100 ms. The capability of the setup is demonstrated by multicolor imaging of fixed liver endothelial cells (LSECs) and mouse brain tissue slices with TIRF- and 2D-SIM with a FOV of up to 230×230 µm² and a lateral resolution of up to 85 nm. Moreover\, an improved version of this setup was used with a wide-field FLIM detector for super-resolved FLIM-SIM\, which was applied for live-cell imaging and dye-multiplexing. \nSpeakers: Dr. Henning Ortkrass & Mr. Manuel Kunisch\nBielefeld University \nBiography of the Speakers: \nHenning Ortkrass is PostDoc in the research group of Prof. Dr. Thomas Huser in the field of biomolecular photonics. He obtained his PhD in 2024 with a thesis on novel approaches on super-resolution structured illumination microscopy (SIM)\, including the development of a large-FOV\, multi-color\, high-speed\, fiber-based TIRF-SIM system. Additionally\, he developed and applied a compact\, cost-efficient\, interferometric SIM system for joint fluorescent lifetime imaging microscopy. These systems were successfully used in live-cell applications. Besides his research focus on novel soft- and hardware solutions for more versatile SIM microscopy\, he currently prepares a start-up company to make this methods more user-friendly and commercially available. \nManuel Kunisch is PhD student at the Biomolecuar Photonics lab led by Thomas Huser at the Bielefeld University. He obtained his Bachelor’s degree in 2021 with a thesis about the fast reconstruction of hyperspectral coherent Raman scattering (HS-CRS) data. In this context\, a Python-based reconstruction tool with a user-friendly GUI was conceived and is still under development to facilitate the creation of false-color coded images from hyperspectral data separating distinct molecular groups based on their spectral response in individual channels. \nOrganiser: Professor Kenneth K.Y.

SUMMARY:What is the Value of Magnetic Resonance Elastography (MRE) for Clinical and Cognitive Brain Science?
DESCRIPTION:Joint Seminar Organised by the Department of Electrical & Electronic Engineering & Department of Psychology \n \nDate: 9 October 2024 (Wednesday)\nTime: 4:00 pm – 5:00 pm\nVenue: Room 1103\, 11/F\, The Jockey Club Tower\, The University of Hong Kong \nZoom Meeting (For participants who couldn’t attend the Seminar in person):\nhttps://hku.zoom.us/j/6985555998?pwd＝V05yTGJWNTlzazd2OFZ0Q3FReHVkdz09\nMeeting ID: 698 555 5998 I Password: Psyc \nAbstract:\nMagnetic Resonance Elastography (MRE) is a Magnetic Resonance Imaging (MRI) technique that receives close attention because it allows non-invasive measurement of a fundamental physical quantity\, namely the mechanical properties (i.e. elasticity and viscosity) of tissues. The technique was first described in a publication in the journal Science in 1995 (Muthupillai et al.\, 1995). Mechanical vibrations are introduced in the organ of interest via an appropriate actuator and the acoustic waves that are produced are imaged by using a phase sensitive MRI technique. Tissue stiffness is related to the speed of the propagating waves and mathematical inversion techniques are applied to produce a parametric map that is referred to as an elastogram. The capability to perform MRE is now available on 1\,000’s of commercial MRI systems worldwide and application of MRE to grade the severity of fibrosis in patients with liver disease is replacing the need for invasive biopsy. Meanwhile a substantial body of research has been performed concerning the study of the brain and which will be reviewed. The MRE technique offers the possibility of exquisite sensitivity through an inherently large dynamic range and robust quantification\, and of particular interest will be to consider the resources that are required to establish potential new research projects in clinical and cognitive neuroscience concerning brain MRE. The presentation will conclude with a glimpse into the future and consideration of what is state of the art in MRE research and how MRE is influencing clinical practice. \nSpeaker:\nProf. Neil Roberts\nChair of Medical Physics and Imaging Science\,\nUniversity of Edinburgh\, UK \nBiography of the Speaker:\nAfter graduating in Physics from the University of Liverpool\, Neil was awarded a Personal Fellowship from the Natural Environment Research Council (NERC) and subsequently moved to the USA where he was Research Associate at University of California in Santa Barbara (UCSB). Returning to the UK\, Neil was appointed Lecturer at the University of Liverpool\, Magnetic Resonance and Image Analysis Research Centre (MARIARC)\, which was built to house the UK’s first commercial Magnetic Resonance Imaging (MRI) system\, to set up an Image Analysis Laboratory\, and where he was subsequently appointed Director. In 2009 Neil was appointed Chair of Medical Physics and Imaging Science at the University of Edinburgh and is based in the Centre for Reproductive Health (CRH) in the Institute for Regeneration and Repair (IRR). \nNeil’s chosen research is quantitative Magnetic Resonance Imaging (qMRI) and he has published over 200 relevant peer-reviewed scientific articles concerning application of different MRI techniques ( e.g. structural MRI\, DTI\, ±MRI\, MRS) in clinical research and especially in clinical and cognitive neuroscience. Most prominent is the technique of Magnetic Resonance Elastography (MRE) for non-invasive measurement of tissue mechanical properties\, and in collaboration with Dr. Richard Ehman at the Mayo Clinic\, Minnesota\, USA this is being applied in studies of the uterus with Professor Hilary O.D. Critchley at the University of Edinburgh\, of brain with Professor Meiyun Wang\, Henan Academy of Science\, ZhengZhou\, China and Professor Yoshiyuki Watanabe\, Shiga University of Medical Science (SUMS)\, Japan and of muscle with Dr. Uraiwan Chatchawan\, Khon Kaen University (KKU)\, Thailand. \nDetails of the Seminar: https://psychology.hku.hk/events/2024-10-09 \n  \nEnquiry: bbecker@hku.hk \nAll are welcome! We look forward to seeing you.

SUMMARY:Ultrasound and Microbubbles for Anticancer Drug Delivery: From Physics to Clinics
DESCRIPTION:Abstract\nUltrasound\, in conjunction with microbubbles\, offers a promising drug delivery method. This approach\, known as sonoporation\, enables targeted drug delivery by temporarily permeating biological barriers (e.g.\, cell membrane\, vessel wall) under ultrasound insonation. It shows potential for a wide range of therapeutic agents\, including chemotherapeutics\, nucleic acids\, peptides\, and antibodies. While preclinical studies have demonstrated promise\, several challenges must be addressed for clinical translation. These include standardizing ultrasound parameters\, selecting suitable microbubbles\, identifying optimal clinical applications\, and resolving questions about administration methods and treatment schedules. Additionally\, the type and concentration of microbubbles\, as well as their response to ultrasound activation\, play critical roles. The ultimate goal is to facilitate the adoption of this technology in clinical settings\, and ongoing and future trials aim to further advance drug delivery through sonoporation. \nSpeaker\nDr. Ayache BOUAKAZ\nIEEE Ultrasonics Distinguished Lecturer\,\nResearch Director of the INSERM Imaging and Brain Institute (iBrain)\,\nUniversity of Tours\, France \nBiography of the Speaker\nDr. Ayache BOUAKAZ obtained his Master degree and his PhD in acoustics in 1992 and 1996 at the National Institute of Applied Sciences in Lyon\, France (INSA Lyon).

SUMMARY:Integrated Sensing and Communications at Mobile Edge
DESCRIPTION:Abstract\nThe emergence of the metaverse and digital twin technologies necessitates addressing key challenges in mapping the large-scale physical world to virtual domains. Integrated sensing and communication techniques\, particularly wireless communications and radar sensing in millimetre-wave bands\, will play a crucial role in achieving this goal and will be a significant enabling technology for 6G networks. The newly introduced sensing function at the mobile edge presents two main challenges: merging sensing information with existing sensors and ensuring efficient data transmission. As different sensors have different data modalities\, this talk will first discuss the recognition under multi-modal dataset. With the help of Variational Autoencoders\, data from different modalities are mapped into a latent variable space with the same prior distribution. As a representation of the original data\, the latent variables contain higher-level semantic information\, thereby simplifying the recognition task. Then\, novel federated learning algorithms to ensure the data privacy at mobile edge and reduce the communication traffic will be presented. \nSpeaker\nProf. Arumugam Nallanathan\nProfessor of Wireless Communications\,\nQueen Mary University of London \nBiography of the Speaker\nProf. Arumugam Nallanathan is Professor of Wireless Communications and the founding head of the Communication Systems Research (CSR) group in the School of Electronic Engineering and Computer Science at Queen Mary University of London since September 2017.

SUMMARY:RPG Seminar – Stretchable\, Sticky\, and Sensorized Hydrogel Dressing for Wound Monitoring System
DESCRIPTION:Abstract\nChronic wounds resulting from underlying diseases like diabetes pose a significant healthcare challenge\, necessitating continuous monitoring and timely intervention to avoid medical complications. Smart bandages integrating multifunctional sensors offer the potential for monitoring chronic wounds caused by diabetes and other underlying diseases\, thereby relieving hospitals from labor-intensive analysis and avoiding medical delays. We fabricated a stretchable organic electrochemical transistor (OECT)-based sensing technology which is a reference electrode-free technique with high sensitivity and excellent tissue compatibility. To ensure patient comfort and convenience\, the OECT-based glucose sensors are seamlessly integrated into a coin-sized wearable readout system and a durable hydrogel dressing patch. In the end\, we also integrated a conductive hydrogel dressing for wound healing. This innovative design renders the sensors imperceptible to patients\, promoting compliance with the monitoring regimen. This work represents a significant step forward in developing digital wearables for chronic wound care and holds promise in transforming the landscape of chronic wound management. \nSpeaker\nMr. Cui Binbin\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the speaker\nMr. Binbin Cui received his B.S. in Applied Chemistry from Nankai University.

SUMMARY:RPG Seminar – Detect The Undetectable in Wearables and Human-Machine Interfaces: pM-Level Biomolecular Detection with ETRS
DESCRIPTION:Abstract\nOrganic electrochemical transistors (OECTs) are emerging as next-generation biosensing technologies due to their capacity to amplify biosignals at low power\, making them particularly suitable for developing sensitive wearable sensors capable of detecting low-concentration biosignals. Current technologies predominantly focus on maximizing the transconductance (amplification capability) of OECTs\, which proves effective for direct electrophysiological detection. However\, in the case of complex biochemical sensing\, involving a multi-stage reaction\, the detection limit depends not only on the amplification capacity but also on the reactions at the gate electrode. In this study\, we introduce the concept of OECTs resonant spectroscopy\, where we have found that a resonant frequency exists\, which can lower the limit of detection (LoD) of the sensor by 1-2 orders. The resonant frequency reflects the peaking synergy at which the dynamic binding-debinding process of targeted molecules and the transconductance of OECTs achieve optimal coupling. The proposed resonance-mode OECTs could serve as a new paradigm applicable to a wide range of biosensing applications that demand higher sensitivity. \nSpeaker\nMr. Tian Xinyu\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the speaker\nMr. Xinyu Tian received his B.Eng in Control & Measurement Technology and Instrument from Tianjin University and M.Sc. in Material Science Engineering from the University of California\, San Diego He is currently a Ph.D. student in the WISE Research Group working on miniaturized OECTs systems for wearable applications.

SUMMARY:RPG Seminar – Coin-sized\, Fully Integrated\, and Minimally Invasive Continuous Glucose Monitoring System Based on Organic Electrochemical Transistors
DESCRIPTION:Abstract\nContinuous glucose monitoring systems (CGMs) are critical toward closed-loop diabetes management. The field’s progress urges next-generation CGMs with enhanced antinoise ability\, reliability\, and wearability. Here\, we propose a coin-sized\, fully integrated\, and wearable CGM\, achieved by holistically synergizing state-of-the-art interdisciplinary technologies of biosensors\, minimally invasive tools\, and hydrogels. The proposed CGM consists of three major parts: (i) an emerging biochemical signal amplifier\, the organic electrochemical transistor (OECT)\, improving the signal-to-noise ratio (SNR) beyond traditional electrochemical sensors; (ii) a microneedle array to facilitate subcutaneous glucose sampling with minimized pain; and (iii) a soft hydrogel to stabilize the skin-device interface. Compared to conventional CGMs\, the OECT-CGM offers a high antinoise ability\, tunable sensitivity and resolution\, and comfort wearability\, enabling personalized glucose sensing for future precision diabetes health care. Last\, we discuss how OECT technology can help push the limit of detection of current wearable electrochemical biosensors\, especially when operating in complicated conditions. \nSpeaker\nMr. Bai Jing\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the speaker\nMr. Jing Bai received his B.Eng. in Software Engineering and B.Mgmt. in Business Administration at Xi’ an Jiaotong University.

SUMMARY:RPG Seminar – Stretchable Organic Electrochemical Transistors for Wearable Applications
DESCRIPTION:Abstract\nOrganic electrochemical transistors (OECT) have emerged as a promising technology paradigm for wearable healthcare applications. However\, several major challenges limit their widespread adoption in real-world applications: 1) the lack of conformable and stretchable OECT units to reduce the mechanical mismatch between devices and the soft human body; 2) the lack of reliable fabrication methods to enable scalable manufacturing of intrinsically stretchable OECT arrays with smaller feature sizes and high density; and 3) the lack of miniaturized readout systems to enable wearable-sized assembly for practical on-body applications. Herein we present a wearable\, integrated\, and soft electronic (WISE) platform based on intrinsically stretchable OECT arrays\, addressing all these challenges. The WISE-platform achieves: 1) intrinsically stretchability (>50%) by establishing a standardizable material protocol for device assembly; 2) a scalable fabrication of stretchable OECTs arrays with feature size down to 100 μm using a high-resolution 6 channel inkjet printing system; and 3) a customized\, coin-sized data readout system for easy acquisition of biosignals at their origin. As an example\, we demonstrate the use of the coin-sized\, smartwatch-compatible electronic module for wearable in-sensor computing at the edge\, but other application scenarios can be easily imagined. \nSpeaker\nMr. Liu Dingyao\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the speaker\nDingyao Liu received his B.Sc. in Applied Chemistry from Xi’an Jiaotong University and M.Eng. in Polymer Science and Engineering from Sichuan University.

SUMMARY:Mechanism Design for Federated Learning with Unstateful Clients
DESCRIPTION:Abstract\nFederated learning (FL) is an attractive distributed machine learning paradigm that enables numerous clients to collaboratively train a model under the coordination of a central server\, while keeping the training data private. However\, without sufficient incentive\, clients may be reluctant to participate in FL due to the associated training costs and variant availability. Moreover\, clients’ availability can be inconsistent\, leading to periodic or random participation—a phenomenon known as unstatefulness. This variability renders existing incentive mechanisms\, designed for full or partial client participation throughout the entire training process\, ineffective. \nIn this talk\, we propose a game-theoretic incentive mechanism for FL with randomized client participation\, where the server adopts a customized pricing strategy to motivate clients to participate at different levels (probabilities). Each client responds to the server’s monetary incentive by choosing its optimal participation level to maximize its profit\, considering both the incurred local cost and its intrinsic value for the model. We show that intrinsic value (internal motivation) introduces the intriguing possibility of bidirectional payments between the server and clients\, leading to a more efficient pricing strategy and enhanced model performance. \nSpeaker\nProf. Bing Luo\nAssistant Professor of Data and Computational Science\,\nDuke Kunshan University (DKU) \nBiography of the Speaker\nProf. Bing Luo is an Assistant Professor of Data and Computational Science at Duke Kunshan University (DKU).

SUMMARY:Asymptotic Capacity of 1-Bit MIMO Channels: From Bayesian Statistics to Large-Scale MIMO Communications
DESCRIPTION:Abstract\nLarge-scale MIMO systems utilizing low-resolution analog-to-digital converters (ADCs) have emerged as a cost-effective and energy-efficient solution for future wireless communication networks. While extended research has been conducted on signal processing and transceiver design in these systems\, the fundamental Shannon capacity limit remains elusive. In this talk\, we introduce a novel approach that leverages information-theoretic asymptotics from Bayesian statistics to derive the Shannon capacity of such systems. We reveal the critical role of the Fisher information and Jeffreys’ prior in this characterization\, and demonstrate how to apply this method to derive the asymptotic capacity of 1-bit MIMO channels in the Gaussian and the (coherent and non-coherent) fading cases. \nSpeaker\nProf. Sheng Yang\nFull Professor\,\nParis-Saclay University \nBiography of the Speaker\nProf. Sheng Yang received the B.E. degree in electrical engineering from Jiaotong University\, Shanghai\, China\, in 2001\, and both the engineer degree and the M.Sc. degree in electrical engineering from Telecom Paris\, France\, in 2004\, respectively.

SUMMARY:IEEE EDS Distinguished Lecturer Seminar: Key Considerations for Obtaining High Performance Contact-controlled Thin-film Transistors
DESCRIPTION:Abstract\nSource-gated transistors (SGTs) have a relatively long history of development but only recently have mainstream technologies allowed for their effective implementation at scale. This talk is addressed to those interested in efficient analog and mixed signal design with advanced thin-film transistors.

SUMMARY:Variational Bayesian Inference for Sensing Over Wireless Networks
DESCRIPTION:Abstract\nFuture wireless networks are envisioned to provide ubiquitous sensing services\, driving a substantial demand for high-accuracy and low-complexity estimation algorithms. Variational Bayesian inference (VBI) provides a powerful tool for modeling complex estimation problems and leveraging prior information\, but poses a long-standing challenge on computing intractable posterior distributions. In this talk\, we propose two problem formulations that are suitable for different sensing scenarios. In the first formulation\, the sensing problem is modeled as a multi-dimensional non-convex parameter estimation. We propose a parallel stochastic particle VBI (PSPVBI) algorithm to solve this challenging problem. Due to innovations like particle approximation\, added updates of particle positions\, and parallel stochastic successive convex approximation (PSSCA)\, PSPVBI can flexibly drive particles to fit the posterior distribution with acceptable complexity\, yielding high-precision estimates of the target parameters. Furthermore\, additional speedup can be achieved by deep-unfolding this algorithm to obtain a learnable PSPVBI (LPSPVBI). In the second formulation\, the sensing problem is modeled as a structured compressive sensing with a dynamic grid. The state-of-the-art expectation maximization based compressed sensing (EM-CS) methods have a relatively slow convergence speed and each inner iteration in the E-step involves a high-dimensional matrix inverse in general. To better address this problem\, we propose an alternating estimation framework (called AE-SC-VBI) based on a novel subspace constrained VBI (SC-VBI) method\, in which the high-dimensional matrix inverse is replaced by a low-dimensional subspace constrained matrix inverse. We further prove the convergence of the SC-VBI to a stationary solution of the Kullback-Leibler divergence minimization problem. Finally\, we apply the LPSPVBI and AE-SC-VBI to solve several important sensing problems\, including multi-band WiFi sensing and TDD massive MIMO channel extrapolation. Simulations demonstrate that the proposed VBI-based algorithms can achieve a much better tradeoff between complexity per iteration\, convergence speed\, and performance compared to the state-of-the-art algorithms. \nSpeaker\nProf. An LIU\nAssociated Professor\,\nCollege of Information Science and Electronic Engineering\,\nZhejiang University \nBiography of the Speaker\nProf. An LIU (Senior Member\, IEEE) received the B.S. and Ph.D. degrees in electrical engineering from Peking University\, China\, in 2004 and 2011\, respectively.

SUMMARY:Developing of Stable Multimode Neural Interface for Brain Activity Detection and Modulation
DESCRIPTION:Speaker\nDr. Xiaoling WEI\nShanghai Institute of Microsystem and Information Technology\,\nChinese Academy of Sciences \nAbstract\nImplanted neural electrodes provide one of the most important neuro-techniques that are able to direct detect individual neuron electrical activities in the living brain. However\, there are three factors we need to consider for the further application of the electrodes for the Brain Machine Interface\, namely\, they are high-throughput\, low trauma and longevity. Ultraflexible neural electrodes have shown superior stability compared to rigid electrodes in long-term in vivo recordings\, owing to their low mechanical mismatch with brain tissue. To detect neurotransmitters as well as electrophysiology for months long is desirable in brain science. This talk I will cover our recent work on a novel stable electronic interface that can simultaneously detect neural electrical activity and dopamine concentration in deep brain. Also\, I will talk about some work related to silk fibroin-based bioelectronic devices for recording and modulation of neurons. \nSpeaker\nDr. Xiaoling WEI\nShanghai Institute of Microsystem and Information Technology\,\nChinese Academy of Sciences \nBiography of the Speaker\nDr. WEI received his B.Eng. degree in 2008 from the Department of Polymer Science and Engineering\, the University of Science and Technology of China and PhD degree in 2013 from the Department of Chemistry\, the Chinese University of Hong Kong. After one more year as a postdoctoral associate in the Hong Kong Polytechnic University\, he carried out his postdoctoral research (2014/11 – 2018/08) in Department of Biomedical Engineering\, the University of Texas at Austin (USA). Since September 2018\, he moved to Shanghai Institute of Microsystem and Information Technology\, the Chinese Academy of Sciences. He has authored and co-authored over more than 30 peer reviewed scientific articles\, including Science Advances\, Advanced Science\, Microsystem & Nanoengineering etc. His research interests are implantable devices\, neural interface and BioMEMS. \nOrganizer\nProf. Zhiqin CHU \nAll are welcome! We look forward to seeing you!

SUMMARY:Mechano-nanooncology
DESCRIPTION:Abstract\nNanomedicines are an important means of treating solid tumors\, but in clinical applications\, they can only reduce side effects and cannot significantly improve efficacy. The main reason is that the rapid clearance of the reticuloendothelial system (RES) and the abnormal mechanical microenvironment of solid tumors limit the delivery efficiency of nanomedicines.The RES blockade strategy can temporarily and reversibly delay liver clearance\, improve tumor enrichment and antitumor effects of nanomedicines\, and have good biological safety. However\, the large number of nanoparticles in the circulatory system still imposes an additional burden on RES\, making it particularly important to improve the efficiency of the RES blockade strategy. We systematically explored how to use the mechanical properties of nanogel to overcome the clearing effect of RES\, and proposed the treatment strategy of antitumor effect of nanomedicines with mechanical modulation for the first time. Crucially\, RES blockade strategy based on the mechanical properties of nanogel boosts antitumor efficacy of marketed nanomedicines\, such as Doxil® And Abraxane®. Therefore\, mechano-based RES blockade has broad universality and huge clinical application potential. We propose using hyperbaric oxygen and mild photothermal therapy to improve the abnormal mechanical microenvironment of solid tumors and enhance the antitumor effect of nanomedicines. For the first time\, we discovered that hyperbaric oxygen can overcome tumor hypoxia and inhibit tumor associated fibroblasts\, regulate the abnormal mechanical microenvironment of solid tumors\, as well as the structure and function of tumor blood vessels\, thereby selectively enhancing the commercialized nanomedicines\, e.g.\, Doxil® and Abraxane® and nanoscale biological macromolecules\, such as PD-1 antibodies. In addition\, we have confirmed that the mild photothermal effect of nanomedicines efficiently depletes tumor associated fibroblasts and extracellular matrix\, reduces solid stress and stiffness of tumors\, normalizes tumor vascular structure and function\, promotes subsequent nanomedicine and oxygen delivery\, damages the ecological niche of tumor stem cells\, eliminates cancer stem cells\, and augments the antitumor effect of nanomedicines. Our results indicate that mechano-mediated regulation strategies have the potential to enhance the antitumor effect of nanomedicines. Two prospective trials have been performed in bedside. \nSpeaker\nProf. Zifu LI\nFull Professor\,\nHuazhong University of Science and Technology \nBiography of the Speaker\nProf. Zifu LI received the B.S. degree from Huazhong University of Science and Technology in 2008 and the Ph.D. degree from the Chinese University of Hong Kong in 2012.
