Smaller, faster-charging batteries are the answer for affordable and sustainable electric vehicles (EVs) for everyone, everywhere. The ability to quickly refill energy is profoundly important in order to reduce EV cost and demand for critical minerals. In this talk I will present asymmetric temperature modulation (ATM) approach to enabling 10-minute fast charging of energy-dense Li-ion batteries in any temperatures (even at -60°C) while still delivering remarkable cycle life. Recent disastrous events at EV charging stations caused by an arctic blast in Chicago will be given as an example of the dire need for quick energy refill in the extreme cold. Battery fast charging must also work in hot summers along with high-temperature stability of cycling and storage. We shall present novel thermal management concepts for extreme fast charging in both extreme cold and hot conditions. Overall, our development points to a new paradigm of battery design and thermal management without having to trade-off among fast charge, safety, lifetime, and cost.

I will discuss how co-speech (i.e., speech-accompanying) gestures relate to language and conceptualisation underlying language. I will focus on “representational gestures”, which can depict motion, action, and shape or can indicate locations. I will provide evidence for the following two points. Various aspects of language shape co-speech gestures. Conversely, the way we produce co-speech gestures can shape language. I will discuss these issues in relation to manner and path in motion event descriptions, clause-linkage types in complex event descriptions, and metaphor. I will conclude that gesture and language are parts of a "conceptualisation engine”, which takes advantage of unique strengths of spatio-motoric representation and linguistic representation.

The relationship between language experience and cognitive control (e.g., working memory, inhibitory control, cognitive flexibility) could be very well illustrated by the cognitively demanding language experience of interpreting training. A series of our empirical studies with interpreting students (see DONG 2023 for a review), together with studies with professional interpreters in the literature, suggest that interpreting training may first enhance students’ working memory (WM) updating ability and then WM spans, with probable some decline of WM updating ability between the shift from the two WM abilities. Similar patterns may appear in other cognitive control functions, such as cognitive flexibility (first with switching cost reduced and then with mixing cost reduced) and multi-tasking coordination. These results could be explained by the task features of interpreting (including task schemas and their cognitive loads) (see DONG & LI 2020), suggesting a close and dynamic relationship between language experience and cognitive control.

The lecture commenced with a warm welcome address by Prof. CHEN Qingyan, Director of PAIR, followed by a brief speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation) of PolyU. In his presentation, Prof. Yang highlighted that urgent need for tissue/organ biomanufacturing owing to the shortage of donation for organ transplantation. He pointed out some challenges in the in vitro manufacturing of tissues/organs, particularly in relation to accurate design, precise fabrication, and functional induction, which underscore the imperative need for new methods for tissue/organ manufacturing. Next, Prof. Yang outlined the development roadmap of biomanufacturing and shared specific examples demonstrating the research progress in 3D bioprinting. In concluding his presentation, Prof. Yang shared his insights on the future direction for biomanufacturing, as well as some significant accomplishments by him and his team at Zhejiang University in the field.
A question-and-answer session moderated by Prof. Wang was followed. Both the online and on-site audience had a fruitful discussion with Prof. Yang.

粵語,又稱「廣東話」,是香港最常用的語言。來自世界各地的學生可透過學習粵語,認識生活中常用的粵語詞句,應付日常溝通需要,從中更好地了解香港,融入香港。為此,我們開發了一個量身定制的在線粵語學習平台──翻轉粵語教室,按大學課程所學,制作相關的多媒體自習材料,讓學生可於上課前,利用網絡、智能手機等學習工具預習各單元的學習內容,然後回校再進行互動的粵語學習,提升學習成效。

香港人講「懶音」的情況愈來愈普遍,如「女仔」說成「呂仔」(n-、l-不分),「過」、「個」不分(gw-、g-不分),「講解」說成「趕解」(-ng、-n不分),「襪」、「默」不分(-t、-k不分)等等。
為了加強學生對粵語的敏感度,協助學生說出流利的粵語,提升整體的表達能力,我們申請了香港理工大學「教學發展及語文培訓補助金」(Teaching Development and Language Enhancement Grant for Language Enhancement Activities, LEG16-19/SS/CBS9),開展「『粵語懶音測試及糾正』網站」計劃。此計劃的目的是協助學生以標準的粵語作日常的交際溝通,減少懶音,以恰當、得體的粵語與外界接觸,完成傳意任務。

由於漢字數量多、結構複雜,香港學生寫錯別字的情況甚為普遍。進入大學後,學生主要使用電腦輸入文字,手寫中文的機會更大為減少,導致錯別字的問題愈見嚴重。多年來,不少學者已就此問題進行各項研究,而坊間的相關參考專書更是汗牛充楝,不可勝數。然而,上述所論多從傳統的形音義角度出發,較少從文體、語境方面加以深入討論。
有見及此,我們去年申請了香港理工大學「教學發展及語文培訓補助金」(Teaching Development and Language Enhancement Grant for Language Enhancement Activities, LEG16-19/SS/CBS10),開展「『專業文體的錯別字糾正』網站」計劃,旨在探討於特定場合或行業語境下之實用文類的錯別字問題,藉以協助學生準確書寫各類職場文書,以恰當、得體的書面語言與外界接觸,完成傳意任務。

PAIR distinguished lecture series: an overview of high performance computing and future requirements
In this talk, we examine how high performance computing has changed over the last ten years and look toward the future in terms of trends. These changes have had and will continue to impact our numerical scientific software significantly. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic, distributed, and parallel environments. Some of the software and algorithm challenges have already been encountered, such as the management of communication and memory hierarchies through a combination of compile-time and run-time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run-time environment variability will make these problems much harder.
