报告一
报告题目:New Developments in 3D Biomimetic Platforms and Biosensors
报告人:Prof. Stella PANG
报告摘要:
Understanding cancer cell motility, which is important in metastasis process, potentially brings new insights in cancer therapy and prevention. Cells migrate in different ways depending on cell types and degree of differentiations. Nanoimprint technology and structured surfaces are used to generate three dimensional (3D) biomimetic platforms to control the migration characteristics of various cell lines. Using shallow topographical patterns, cells from different histological origins showed different migration speed and directionality. The nanoimprinted 3D platforms when integrated with advanced structured surfaces and biosensors could be a novel in vitro tool for invasiveness assessment.

报告题目:Massive Random Access: Fundamental Limits, Optimal Design, and Applications to M2M Communications
报告人:Dr. Lin DAI
报告摘要:
In this talk, Lin Dai will introduce my recent work on modeling and performance optimization of random-access networks. Lin Dai will first show that a random-access network in general can be regarded as a multi-queue-single-server system, and the key to performance analysis lies in proper characterization of the service time distribution, which is difficult to obtain with either each node’s queue completely ignored or interactions among nodes’ queues taken into full consideration. Lin Dai will then introduce our newly proposed node-centric model, and demonstrate how to establish a unified analytical framework to characterize the fundamental limits of random-access networks. Lin Dai will conclude the talk by demonstrating how to apply the proposed theory to guide the optimal access design of M2M communications in LTE networks.
报告人简介:
Lin Dai was a co-recipient of the Best Paper Award at IEEE Wireless Communications and Networking Conference (WCNC) 2007, and the IEEE Guglielmo Marconi Prize Paper Award (the annual Best Paper Award of IEEE Transactions on Wireless Communications) in 2009.

报告题目:Applications of Nonlinear Laser Dynamics in Microwave Photonics
报告人:Dr. Nelson S.C. CHAN

报告摘要
This talk will summarize some recent developments in the applications of these nonlinear dynamics as exemplified by the so-called period-one (P1) state and chaotic state. In P1 states, the laser can be applied for radio-over-fiber communication as a photonic microwave oscillator with high frequency-stability, optical controllability, and wide frequency-tunability. In chaotic states, the laser can be applied for random bit generation in cryptography with minimal electronics at bit rates exceeding 0.2 Tbps. Specifically, we recently developed a scheme employing a fiber Bragg grating (FBG) for a simple and high-quality generation of random bits. Some fundamental issues related to the entropy associated with the laser dynamics will also be discussed.

报告题目:Discrete Huygens‘Metasurface and Huygens’Box: Frontiers in Electromagnetic Metasurfaces
报告人:Dr. Alex M. H. WONG
报告摘要

The first part of this talk examines the benefits to designing and implementing an aggressively discretized metasurface. This will be exemplified by metasurface designs of a near-grazing angle retroreflector and a perfect anomalous electromagnetic reflector. The latter part of this talk explores possibilities which avails us as we wrap a metasurface around a closed area. Simulations and experimental results will be presented which demonstrate the generation of an arbitrary waveform inside a metallic cavity. The talk will conclude with on implications and inspirations drawn from the aforementioned endeavors.
