Abstract Algorithms for mobile robotic systems are generally implemented on purely digital computing platforms. As complementary metal-oxide-semiconductor (CMOS) scaling approaches the end of the road, the improvement of the throughput of digital processors and computing power efficiency is nearing its end. This issue not only affects the power requirements of large data centers but also […]

Abstract The emergence of flexible and wearable electronics is now leading a revolutionary era for real-time healthcare monitoring and human-machine interaction (HMI) in a more convenient and authentic manner. Sensors, as the bridge between human beings and electrical terminals, are playing an important role in facilitating interaction with the complex environment and promoting the healthy […]

Abstract This seminar aims to introduce reinforcement learning (RL) and its application to communication systems to graduate students, although everyone is welcome to attend. RL has successfully been applied to many application domains ranging from control of communication and computer systems, navigation of driverless vehicles, robots and flying drones, to guiding medical imaging and surgery, […]

Abstract Colloidal quantum dots (QDs) have been of great interest owing to the unique optical and electrical properties, such as size-dependent band gap tunability, wide absorption and narrow emission spectra, and controllable surface properties. Recently, several types of opto- and nano-electronic devices utilizing QDs have been reported for future optoelectronics. The QD-based light-emitting diodes, QLEDs, […]

Please note the seminar venue is revised to Tam Wing Fan Innovation Wing Two, The University of Hong Kong. Abstract Ultrasound is undoubtedly a popular medical imaging modality and is becoming known for its high-frame-rate imaging capabilities. However, high-frame-rate ultrasound has yet to flourish in point-of-care applications due to the lack of suitable portable hardware, […]

Abstract Given its high mobility, high breakdown voltage and decent thermal conductivity, GaN technologies have shown great promise for high-power high-frequency (HP-HF), rapidly rising as a front runner for mm-wave to THz analog/RF circuits for IoT and 5G/6G wireless communication. Meanwhile, it is also heavily explored for power electronic applications for fast charging, data center, […]

Abstract Nanomedicines 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 […]

Speaker Dr. Xiaoling WEI Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences Abstract Implanted 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 […]

Abstract Future 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 […]

Abstract Federated 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, […]
