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: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: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: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. He serves as the principal investigator and director of the NSF AI Institute for Edge Computing – Athena\, the NSF Industry-University Cooperative Research Center for Alternative Sustainable and Intelligent Computing (ASIC)\, and the co-director of the Duke Center for Computational Evolutionary Intelligence (DCEI). Dr. Chen is the author of over 600 publications and holds 96 US patents. His works have been recognized with numerous awards and honors\, including the IEEE Circuits and Systems Society’s Charles A. Desoer Technical Achievement Award and the IEEE Computer Society’s Edward J. McCluskey Technical Achievement Award. He is a Fellow of AAAS\, ACM\, IEEE\, and NAI\, and the inaugural Editor-in-Chief of IEEE Transactions on Circuits and Systems for Artificial Intelligence (TCASAI).\n\nOrganiser\nProf. K.B.
