Image Understanding of Pathway Figures in Biomedical Articles

Prof. Dong Xu （美国）

 University of Missouri-Columbia，USA

Abstract

Many high-quality biological pathways are presented in figures and text in the biomedical literature, which is a great resource for biological mechanism studies and precision medicine practices. These pathways need to be carefully curated, reconciled, and transformed into a computable form. Current manual curation approaches are inadequate in keeping up with the pace of the literature growth. New bio-curation approaches are needed to streamline the identification of gene interactions from pathway figures and text. We propose a pathway curation approach for identifying genes and their interactions using both figures and text of biomedical articles. Our method integrates deep learning-based object detection models with Google optical character recognition service to extract genes and their interactions from pathway figures. Our pipeline was evaluated on the figures from PubMed publications with manual annotations. The results demonstrated that our model can effectively retrieve genes and their interactions in pathway figures. The proposed pipeline may accelerate various applications of the latest biomedical discoveries. We also developed a web server to provide the gene interaction curation on uploaded pathway figures and biomedical articles.

Optical detection of singlet oxygen in vitro and in vivo

Prof. Steffen Hackbarth（德国）

 Humboldt-Universität zu Berlin, Germany

Abstract

Oxygen, light and an appropriate drug is all it takes to generate singlet oxygen during Photodynamic Treatment, but is it really that simple? Even though the mechanism behind is understood since the 70s and the related therapy has become a first choice in the treatment of several types of cancer, the treatment results often stay behind expectation. To find out the reason, optical supervision, not only of the generated singlet oxygen, but also its interactions is necessary. This presentation shall take you on a journey how the knowledge on singlet oxygen kinetics in cells and tissue evolved up to the most recent findings. This subject is a perfect example how much the detection setup and the applied model can influence and even falsify the results. On the other hand, it shows how an interdisciplinary approach can handle the problems and turn unwanted findings into opportunities for future developments.

Advances of Carbon Nanotube Field Effect Transistors for Ultralow Power Applications

Prof. Qing Zhang（新加坡）

 Nanyang Technological University, Singapore

Abstract

Ultralow power signal processing is in great demand especially for remote sensing circuitry in IoT systems, implantable devices in health-care systems, etc. which usually need to work under a limited battery lifetime or a battery-less energy harvesting scheme. To significantly reduce the power consumption of MOSFETs and CMOS circuits, operating MOSFETs in the subthreshold region could be an optional solution. Unfortunately, subthreshold operation of silicon or other ordinary semiconductors based MOSFETs generally is very slow. Such slow operations mainly result from the exponentially decreased subthreshold source and drain current at a small biased voltage, leading to slow charging and discharging of the load capacitance. Compared to silicon, single walled caron nanotubes (SWCNTs) offer unique geometrical and electrical properties, e.g. very high intrinsic carrier mobility, very small quantum capacitance and very narrow depletion region, etc. All these excellent properties could make SWCNT-FETs work in the subthreshold region without significantly slowing down their operations. In this talk, I present our work on Schottky barrier (SB) SWCNT-FETs. With a high-k gate dielectric, ultrathin SWCNT channel, and asymmetric gate structure, our SWCNT-FETs demonstrate highly efficient gate electrostatic control over the SWCNT channel and the SB at the source contact, resulting in a steep subthreshold switching characteristic with a small subthreshold swing of ~ 67 mV/dec, a large current on/off ratio of ~ 10⁶, and a low off-state current of ~ 0.5 pA. A PMOS inverter built with the subthreshold SB-SWCNT-FETs exhibits a well-defined logic functionality and small-signal amplification capability under a low supply voltage of ~ 0.5 V and an ultralow-power of £ 1 pW.

Emerging chalcogenide solar cells

Prof. Xiaojing Hao（澳大利亚）

University of New South Wales, Australia

Abstract

Crystalline Si modules dominate the photovoltaic (PV) market and thin film like amorphous-Si, Cu(In,Ga)(S,Se)₂, CdTe, solar cells have all been commercialized to varying degrees of success. Whilst these technologies could feasibly cover the majority of PV applications, most of the established platforms face challenges related to either the use of critical raw materials, toxic elements, long-term stability, conversion efficiency limitations, cost or low technological flexibility. These are all important considerations that must be taken into account as the PV field begins to look towards an era of terawatt level power generation. Increasing the diversity of viable photovoltaic materials is critical to allow greater adaptability as the technology continues to expand and develop not only for further increasing the efficiency/cost but also fulfill various application areas. This encourages a continued search for PV materials, particularly those stable, green, and cheap PV materials. This talk will focus on the promise and recent progress on the emerging chalcogenide solar cells.

Wireless Energy Harvesting and Power Transfer

Prof. Yi Huang（英国）

The University of Liverpool, UK

Abstract

Wireless energy harvesting (WEH) is about how to obtain energy from the wireless environment efficiently while wireless power transfer (WPT) is about how to efficiently transfer energy wirelessly. They are linked by a key device called rectenna: rectifying antenna which is the focus of this talk. Normally WEH should be a broadband system in order to harvest as much energy as possible while WPT is a narrowband system. It is shown that new technologies (such as metamaterials and metasurfaces) can significantly improve the power transfer efficiency and operational distance for WPT systems. They can also improve the energy conversion efficiency of WEH by making the reception less sensitive to incident wave angle and polarization. It is also shown that metamaterial-based rectennas can achieve a higher RF to DC conversion efficiency. Furthermore, metamaterials can also be used as either parasitic elements or loading components to improve WEH performance in terms of circuit size, beamwidth, and conversion efficiency. A range of interesting work in this area at Liverpool will also be reported, including the integration of communication and wireless power transfer.

High-Performance Metamaterials and Applications

Prof. Zhizhang (David) Chen and Yuehe Ge（加拿大）

Email: zz.chen@ieee.org

Abstract

The control of reflection and transmission properties of electromagnetic waves are essential and persistent topics from microwaves to optical waves. Metamaterials, which can realize unprecedented controls of electromagnetic waves, have attracted enormous interest in the past decades. More recently, metasurfaces have emerged and realized full control of electromagnetic waves. They have shown strong potential for development of ultra-thin electromagnetic devices, such as ultrathin metasurface lens, spin-orbit manipulation, metasurface holograms, and some other functional interfaces. Most of the metasurfaces presented so far have been focused on full controls of phases, although attempts have been made to control amplitude and phase separately by designing particular shapes of the unit cell. Along this line, we have developed broadband high-efficiency ultrathin metasurfaces with simultaneous and independent control of amplitudes and phases for both reflection and transmission modes. In addition, by incorporating active devices, such as pin diodes and varactors, the phases of metasurfaces can be dynamically controlled, resulting in low-cost electrically reconfigurable metasurfaces or reconfigurable intelligent surfaces (RISs). In this talk, we will present the above-mentioned novel metasurfaces and their applications. They include 1-bit and 2-bit multi-polarization reflectarray antennas. They present many potential new applications that are not foreseen before.

Overview of Advanced GaN HEMT Modelling and Measurements at NUS

Prof. Yongxin Guo （新加坡）

 FIEEE, National University of Singapore, Singapore

Abstract

GaN HEMT is an ideal candidate for advanced circuit designs in 5^th generation and satellite communication systems due to its inherent advantages such as high power density and high breakdown voltage. The performance of GaN devices is strongly affected by different effects, such as the thermal and trapping effects. Thus, advanced modelling and measurement techniques have been developed to accurately characterize GaN devices and investigate these effects, including pulse, double-pulse, and dynamic-bias techniques. Various large-signal models have been proposed for GaN-based microwave circuit designs, such as physics-based, table-based, empirical, and neural network-based models. In addition, many methods have been developed to model the thermal and trapping effects with great success. However, challenges still exist in the accurate and reliable modeling of GaN HEMTs. This presentation will give an overview of advanced GaN device modelling and measurement by my group at NUS.

Peptide-based Data Storage

Prof. Francis C.M. Lau （中国香港）

 The Hong Kong Polytechnic University, Hong Kong

Abstract

Humans are generating more than one million GB of data each second. According to Statista, we will create a total of 79 ZB (1 ZB = 10^21 bytes) of data in 2021. How to store such a tremendous and ever-increasing amount of data will become an issue. Currently, we use mostly inorganic mate-rials such as magnetic tapes and silicon-based devices for storing data. In the future, is there a possibility that we will use organic data storage systems? In this seminar, we will introduce our recent work on storing data using peptides.

Intelligent Facial Analytics and Applications

Prof. Wen-Huang Cheng（中国台湾）

Yang Ming Chiao Tung University, Taiwan

Abstract

Facial behavior (e.g., facial expressions) is a type of nonverbal communication, which is a result of conscious suppression (intentional) or unconscious repression (unintentional) and can be viewed as a “leakage” of people’s true emotional states or feelings. In recent years, facial behavior understanding has drawn much attention because it can benefit a wide range of ‘smart’ applications through insightful understanding of the user, e.g., clinical diagnosis, depression analysis, customer understanding, and even business negotiation and police interrogation. In facial behaviors, micro-expressions are challenging to be analyzed due to the short span of time (0.5 seconds or shorter) and the fine-grained changes (low-intensity movements of the face). It is also difficult to collect and label micro-expression data. Even for human experts, it takes 2 hours to label a 1-minute video of facial micro-expressions on average. Therefore, this talk aims to present our latest research results on intelligent facial analytics and our experience on shipping the developed inventions and technologies to real applications.

Deep Face Synthesis: Reconstruction, Augmentation, and Animation

Prof. Chia-Wen Lin（中国台湾）

 Tsing Hua University, Taiwan

Abstract

This talk introduces deep face synthesis in three aspects: 1) 3D face reconstruction, 2) face augmentation, and 3) anime-face generation from a single face image. Monocular face reconstruction, aiming to recover the corresponding 3D face model from a single face image, has found a wide range of applications, such as face alignment, face editing, expression recognition, face augmentation, and AR/VR. Face images taken in-the-wild, however, usually involve expressions, poses, and shading with a large range of variety, which can easily degrade the performance of face synthesis. The first part of this talk will introduce a Dual-Stream Face Reconstruction Net (DS-FRN) that consists of a geometry stream and a texture stream to achieve identity-preserving face reconstruction even with facial expressions. In the second part, we present a Domain-transferred Face Augmentation Net (DotFAN) to achieve identity-preserving face normalization/augmentation with various shadings, poses, and expressions. DotFAN can significantly boost the performance of identity recognition. Finally, we demonstrate a framework to translate a portrait photo-face into an anime-face which is style-consistent with a given reference anime-face. Experimental results on public face datasets demonstrate the efficacy of our approaches.
