Quantitative phase and polarization microscope (QPPI) is a useful label-free microscopic tool in revealing the quantitative biophysical information of cells, such as cell shape, dry mass and their subcellular distribution. However, the current existing QPPI system could only offer a low imaging speed which is not sufficient to observe the dynamic activities of the live […]
Optimization problems subject to hard constraints are common in time-critical applications such as autonomous driving and wireless communication. However, existing iterative solvers often face difficulties in solving these problems in real-time. In this talk, we focus on one such problem - the critical optimal power flow (OPF) problem in power system operation. We develop DeepOPF […]
Since 2019, reconfigurable intelligent surface (RIS) has attracted a lot of interests from both academia and industry. In this talk, Professor Jie Zhang will first introduce their pioneering work on Smart Radio Environments back to 2012 in a 2.2 million Euros research project titled “Wireless Friendly Energy Efficient Buildings (WiFEEB)” in which frequency selective surfaces, […]
Nowadays, there is a large effort to find a monolithic solution for photonics and electronics. The main purpose is to integrate materials which have high carrier mobility and high photonic performance for optoelectronic components. In many cases, a 3D integration is required where electrons are processing the data and photons are communicating the data in […]
Micro-printing is a good way to manufacture patterning structures in modern manufacture, which has been widely used in fields, e.g. micro-LED display, benefiting from the high material utilization. The electrohydrodynamic inject printing (EHD-IP) is proven to be with the highest spatial resolution among various micro-printing techniques. Still, the ink control and homogeneity are two main […]
Fiber lasers have been known as compact and robust laser sources. When operating in the femtosecond-pulse regime with high repetition rates (HRRs), particularly at a level of GHz, they open new opportunities for industrial and scientific applications, such as high-speed ablation-cooled material removal, ultrafast measurement, low-photodamage biophotonics, etc. Among various schemes of generating HRR fs […]
As an essential part of intelligent manufacturing, R & D, fabricating, and application of robots become the important manifestation to show the national scientific and technological innovation ability as well as the industrial level. The cable-driven parallel robot (CDPR) combines cable drive technology and parallel mechanism theory, which inherits the high acceleration and load capacities […]
With deeper and deeper penetration of variable renewable energy sources (RES) and distributed energy resources (DER) across the world, new challenges are emerging in terms of their grid and market integration. In this lecture we will illustrate these challenges from a techno-economic perspective, with focus on security and reliability requirements when operating power systems and […]
Artificial Intelligence (AI) is catalyzing a paradigm shift in healthcare, promising to reshape the landscape of patient care. At the heart of this transformation is medical imaging, where AI-enabled technologies hold substantial promise for precise and personalized image-based diagnosis and treatment. Despite these advances, these models often underperform at real-world deployment, particularly due to the […]
Trustworthy machine learning is one of emerging and critical topics in modern machine learning, since most real-world data are easily imperfect, such as online transactions, healthcare, cyber-security, and robotics. Intuitively, trustworthy intelligent system should behave more human-like, which can learn and reason from imperfect data including labels, features, systems and prompts. Therefore, in this talk, […]
In recent years, synaptic electronic devices have gained significant attention for their applications in neural morphological computing and peripheral neural sensing simulations. It is of great significance to further enhance the functionality of these devices to replicate more complex neural transmission processes. The presenter will provide a brief overview of recent advancements in this field […]
My talk will focus on Image Quality Transfer (Alexander et al Neuroimage 2017; Tanno et al Neuroimage 2021; Lin et al ISMRM 2021), and its role in international efforts to democratize MRI expertise and capability, such as the CAMERA network https://www.medrxiv.org/content/10.1101/2022.05.02.22274588 v1.full. The technique aims to use machine learning to estimate high quality images, e.g. […]
