The lecture commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation). In his presentation, Prof. Chen first gave a brief introduction to the United Nations’ 17 Sustainable Development Goals (SDGs) as well as the SDG monitoring practices in Mainland China. He pointed out that the Nation has adopted the high quality sustainable development concept, which emphasises harmonising the social, economic and environmental aspects in national development. Next, he elaborated on a pilot project that he led to measure Deqing County’s progress towards SDGs using geospatial and statistical information. The project was selected by the UN Department of Economic and Social Affairs as one of the first 16 good SDGs’ practices in 2020. After that, Prof. Chen shared that the achievement of sustainable development requires holistic and systematic research to build a digital governance system that can provide the basis for the scientific and orderly development of national territorial space. He also explained how territorial space sustainability studies can help unveil and analyse various patterns, such as the distributions of population, enterprises and public service facilities, and the relationships between them. To conclude, Prof. Chen introduced the national program on the development of the Realistic Geospatial Landscape Model (3dRGLm), which can generate digital description and representation of the real 3D geospatial spaces. This new geographic information system can support the Nation in achieving natural resources management and high quality sustainable development.
A question-and-answer session moderated by Prof. DING Xiaoli, Director of the Research Institute for Land and Space (RILS) and Prof. WENG Qihao, Associate Director of RILS, followed. The online and on-site audience engaged in a productive discussion with Prof. Chen.

Neuroemergentism, (NM) is a novel framework which has sought to consider language development as involving the organization and reorganization of cognition and its underlying neural substrate. Work to support this framework comes from studies of language and cognitive development. In this talk, I will focus on two separate levels, the sensorimotor plasticity needed to adjust to new input and the cognitive flexibility needed to select between these competing sources of information. This talk will discuss both these levels with regard to the neurocognitive adaptations seen in bilinguals. This will include structural brain differences in monolinguals and bilinguals that vary in the age of second language acquisition. In the second part, of the talk work that has focused on the cognitive flexibility will be presented. This will focus on the adaptations of the basal ganglia and frontostriatal tracts as a gating mechanism crucial for selecting the correct motor response. This includes newer work which links genes associated with dopamine to cognitive and language flexibility in bilinguals. The ways in which sensorimotor plasticity and cognitive flexibility represent accurate but incomplete conceptualizations of the competitive processes involved in language and cognitive processing will be discussed. The talk will conclude with potential future directions using an NM framework.

In the lecture, Prof. Batty gave an overview of the development of the science of cities in the last 50 years. Drawing on the system approach and complex theory, he explained that urban science involves top-down and bottom-up thinking; it is a systematic, complex and evolving discipline built on knowledge in social physics, economics, transportation and numerous scientific methods that yield theories. He illustrated this with city morphology examples from the UK and the Greater Bay Areas (GBA) generated by large-scale computer models. At the end of the lecture, Prof. Batty described some challenges with fractal geometry, size and scaling, networks, and building models currently faced by the field, and he suggested the way forward for the discipline.

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.

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.

We have witnessed a rapid expansion of the global Chinese medicines market in recent years. Herb-based products are becoming an integral part of health management not only in the East, but also in the Western world. Notwithstanding the booming of herbal markets, there are challenging issues and concerns from the medical/healthcare professionals, the nutritional/pharmaceutical communities, regulatory agencies, as well as the general public. In this presentation, a closer look will be taken at the scientific challenges of the quality, safety, and effectiveness of herbal products. While some of these difficulties are unlikely to be overcome within a short period of time, there are wide-open opportunities for international collaborative research to help meet the demands for high-quality Chinese medicine products.

Water shortage is one of the biggest challenges that humanity faces. Novel technologies to tackle the challenge of water scarcity are urgently needed. However, all the existing studies are based on bare fibers with diameter in the order of mm. This talk introduces a novel fog collection technology using microfibers fabricated by near-field electrospinning. The collection efficiency reaches a record high level. Systematic investigation reveals that the waterdrops are “visible” to fog droplets in the incoming air flow because of the relatively small size of the microfibers. Thus, the large waterdrops deflect the fog-carrying airflow to the satellite small waterdrops, which effectively intercept the fog droplets.

Psychology, Computer Science and Neuroscience have a history of shared questions and inter-related advances. Recently, new technology has enabled those fields to move from “toy” small-scale approaches to the study of language learning from raw sensory input and to do so at a large scale that constitutes daily life. The three primary goals of my research are 1) to quantify the statistical regularities in the real world, 2) to examine the underlying computational mechanisms operated on the statistical data, and 3) to apply the findings from basic science to real-world applications. In this talk, I will present several projects in my research lab to show that the advances in human learning and machine learning fields place us at the tipping point for powerful and consequential new insights into mechanisms of (and algorithms for) learning.

宣統年間（1909-1911），袁世凱（1859-1916）在攝政王載灃排擠下歸隱彰德府洹上村，與門生故舊唱和，以示無心世務。這些詩作被袁氏次子袁克文（1890-1931）輯錄於《圭塘唱和詩》中，於宣統二年（1910）刊印，其中袁氏詩作共十三題十五篇。1940年代，長子袁克定（1878-1958）將袁世凱當年親筆謄鈔之詩稿影印出版，額曰《洹村逸興》。比對二書之篇目，《圭塘》諸本有袁氏詩作五篇不見於《洹村逸興》。實際上，該五篇之謄抄稿仍與《洹村逸興》之原件共同收藏於社科院近代史所；克定當日不收入書中，蓋因稿上頗有無名氏批點文字，公之於眾可能影響乃父形象。這些批點文字當係某位幕僚所為，內容為修改建議；然參《圭塘》諸本，可知袁世凱對建議幾乎全未採納。本文著眼於五篇詩稿及其批點文字，以討論原詩與修改建議如何優劣互見，乃至這輯詩歌與當時政局之微妙關係。

晚清時期英雄傳記風行一時，引發英雄崇拜的熱潮。但是此時所謂「傳記」，其實是融合諸多資源形構而成的新文類。《意大利建國三傑傳》作為晚清英雄傳記的代表作，充分展示了這一特徵。梁啟超借鑑明治政治小說的多種書寫模式，又援引本土小說的要素，將意大利建國史轉化為中國未來命運的預言，將意大利建國三傑刻畫為智、仁、勇的化身，將兒女情長俠義精神引入傳記書寫。正是由於梁啟超自出機杼的創造與轉化，此類英雄傳記廣受讀者歡迎，成為晚清文學文化史上的典範作品。

This talk begins with an overview of the interconnection between literature and philosophy in modern Chinese literature. Then, it probes into the three existentialist allegories in Fortress Besieged (1947), a philosophical novel written by Qian Zhongshu, a polyglot scholar of East-East comparative literature and philosophy. The novel’s overarching allegory, i.e., a fortress besieged, will be compared in juxtaposition with several philosophical allegories about the mutability and limitations of human life in Western philosophy. This talk concludes with a reflection on the seminal influence of this novel in contemporary Chinese society where “fortress besieged” has become an everyday word referring to one’s existential crisis.

We investigate reversal and recirculation for the stationary Prandtl equations. Reversal describes the solution after the Goldstein singularity, and is characterized by regions in which u > O and u < 0. The classical point of view of regarding the Prandtl equations as an evolution equation in x completely breaks down since u changes sign. Instead, we view the problem as a quasilinear, mixed-type, free-boundary problem. This is a joint work with Sameer Iyer.

Models arising in biology are often written in terms of Ordinary Differential Equations. The celebrated paper of Kermack-McKendrick (19271, founding mathematical epidemiology, showed the necessity to include parameters in order to describe the state of the individuals, as time elapsed after infection. During the 70s, many mathematical studies were developed when equations are structured by age, size, more generally a physiological trait. The renewal, growth-fragmentation are the more standard equations. The talk will present structured equations, show that a universal generalized relative entropy structure is available in the linear case, which imposes relaxation to a steady state under non-degeneracy conditions. In the nonlinear cases, it might be that periodic solutions occur, which can be interpreted in biological terms, e.g., as network activity in the neuroscience. When the equations are conservation laws, a variant of the Monge-Kantorovich distance (called Fortet-Mourier distance) also gives a general non-expansion property of solutions.

Universities conduct research for three reasons: to educate students, to contribute to society, and to understand the world. While society often holds a view of the scholar as a solitary and singular genius, in reality scholars today participate in a highly collaborative, worldwide search for shared understandings that stand the test of time and the scrutiny of others. The problems in the 21st century often demand effort by teams of researchers with resources at scale: laboratories and equipment, compute resources, and expert staffing. Working with faculty, students, and other stakeholders to identify the greatest opportunities and the resources needed to address them is both a privilege and a challenge for modern academic administrators. In this talk, I will share three examples: fostering collaborative proposal-writing; planning for shared capabilities in experimental facilities, data, and computation; and transforming academic structures.

清朝皇族婚入女子的財產權受到法律保障，但是皇族女子的財產權則缺乏法律保障，分產的機會也相對稀少。清朝公主出嫁後對於其陪嫁的人丁、動產與不動產並未擁有完整的所有權，僅擁有占有權、使用權與收益權，而不具備轉讓或出售的處分權，其後代對其亦無繼承權。本文以清代滿洲公主的陪嫁莊頭與壯丁為例，運用清代滿蒙漢文檔案材料和官書典籍，輔以其他二手研究文獻，以出嫁蒙古王公之清朝公主的收支為核心，並聚焦於其妝奩上，探討其財產的所有權、管理機制與公主薨逝後的轉讓情況。最後透過研究公主在崇奉藏傳佛教上的花費，說明清朝公主如何在清朝治理蒙古的政策中起到重要作用。

In this CIHK webinar, we will discuss the material conditions of and historical background to the use of Classical Chinese or Literary Sinitic in writing-mediated brush conversation between literati of Sinitic engaged in cross-border communication within Sinographic East Asia or the Sinographic cosmopolis, which corresponds with today’s China, North Korea, South Korea, Japan (including Okinawa, formerly the Ryukyu Kingdom) and Vietnam. Compared with speech as a modality of communication, real-time writing-mediated interaction between talking humans, synchronously face-to-face, seems uncommon. In any society, speaking is premised on one condition: the interlocutors must have at least one shared spoken language at their disposal, but even then, there are circumstances under which speaking is either physically not feasible or socially inappropriate. Could writing function as an alternative modality of communication when speaking is not an option due to the absence of a shared spoken language, as in cross-border communication settings? Whereas real-time writing-mediated face-to-face interaction is rare where a regional lingua franca was known to exist (e.g., Latin and Arabic), there is ample historical evidence of literati of Classical Chinese or Literary Sinitic from different parts of Sinographic East Asia conducting ‘silent conversation’, synchronously and interactively in writing mode using brush, ink, and paper. Such a pattern of writing-assisted interaction is still practiced and observable in pen-assisted conversation – pen-talk – between Chinese and Japanese speakers today, thanks to the pragma-linguistic affordance of morphographic, non-phonographic sinograms (i.e., Chinese characters and Japanese kanji). We will outline the historical spread of Classical Chinese or Sinitic texts from the ‘center’ to the ‘peripheries’, and the historical background to the acquisition of literacy in Sinitic by the people there. Their shared knowledge of Sinitic helps explain why, for well over a thousand years until the 1900s, literati from these places were able to speak their mind by engaging in ‘Sinitic brush-talk’ 漢文筆談 in cross-border communication.

Focusing on tensions and links between national formation and international outlooks, this talk shows how classical world visions persist as China’s modernizers and revolutionaries adopted and revised the Western nation-state and cosmopolitanism. The concepts of tianxia (all under heaven) and datong (great harmony) have been updated into outlooks of global harmony that value unity, equality, and reciprocity as strategies of overcoming interstate conflict, national divides, and social fragmentation. The talk will delve into two debates: the embrace of the West vs. aspirations for a common world, and the difference between liberal cosmopolitanism and socialist internationalism.

During the sixteenth and early seventeenth centuries, the relaxation of the Ming sea ban, along with the arrival of the Europeans, generated a multipolar environment in East Asia. It revolved around the intra-Asian exchange centered upon Chinese silk and Japanese silver, and a nascent global flow of New World bullion to China and spices for Western Europe. The situation changed during the mid-seventeenth century amid mounting restrictions on overseas contacts from the Tokugawa shogunate of Japan and the consolidation and militarization of Chinese merchants under the Zheng family. By 1683, when the Qing forced the Zheng to surrender and occupied their bastion of Taiwan, China had achieved naval preeminence in the East Asian sea lanes. Other than a few outposts, the Europeans had largely withdrawn from the area north of island Southeast Asia, which remained under the hegemony of the Dutch East India Company. In 1684, the Qing court legalized private trade and travel abroad, prompting another wave of overseas migration. Authorities in China and across eastern maritime Asia enacted policies that kept the Qing merchants and immigrants separate from the earlier Ming loyalists. Additionally, both groups of Chinese were accorded significant political, economic, and legal privileges. This infrastructure, backed by Qing naval power, paved the way for the “Chinese century” in maritime Asia.

古代中國幅員遼闊，習俗各異，如何實行統一管理是一大難題。秦朝用嚴刑峻法移風易俗，激起東方社會的激烈反抗，很快歸於失敗。西漢初年郡國並行，允許東方王國在一定程度上從俗而治。但王國勢力太大，危及國家的統一，文景二帝不得不收奪諸侯王的自治權。為了避免重蹈亡秦覆轍，儒生們提出“德教”主張，其中又包含“以禮為治”和“以德化民”兩種方案。受其影響，武帝以後的朝廷政策繼續表現出大幅度搖擺，至漢末魏晉才確立了基本符合當時國情的治理模式。

Before the advent of computers around 1950, optimization centered either on small-dimensional problems solved by looking at zeroes of first derivatives and signs of second derivatives, or on infinite-dimensional problems about curves and surfaces. In both cases, "variations" were employed to understand how a local solution might be characterized. Computers changed the picture by opening the possibility of solving large-scale problems involving inequalities, instead of only equations. Inequalities had to be recognized as important because the decisions to be optimized were constrained by the need to respect many upper or lower bounds on their feasibility. A new kind of mathematical analysis, beyond traditional calculus, had to be developed to address these needs. It built first on appealing to the convexity of sets and functions, but went on to amazingly broad and successful concepts of variational geometry, subgradients, subderivatives, and variational convergence beyond just that. This talk will explain these revolutionary developments and why there were essential.

Adaptive computation is of great importance in numerical simulations. The ideas for adaptive computations can be dated back to adaptive finite element methods in 1970s. In this talk, we shall first review some recent development for adaptive methods with some application. Then, we will propose a deep adaptive sampling method for solving PDEs where deep neural networks are utilized to approximate the solutions. In particular, we propose the failure informed PINNs (FI-PINNs), which can adaptively refine the training set with the goal of reducing the failure probability. Compared with the neural network approximation obtained with uniformly distributed collocation points, the proposed algorithms can significantly improve the accuracy, especially for low regularity and high-dimensional problems.

Convex Matrix Optimization (MOP) arises in a wide variety of applications. The last three decades have seen dramatic advances in the theory and practice of matrix optimization because of its extremely powerful modeling capability. In particular, semidefinite programming (SP) and its generalizations have been widely used to model problems in applications such as combinatorial and polynomial optimization, covariance matrix estimation, matrix completion and sensor network localization. The first part of the talk will describe the primal-dual interior-point methods (IPMs) implemented in SDPT3 for solving medium scale SP, followed by inexact IPMs (with linear systems solved by iterative solvers) for large scale SDP and discussions on their inherent limitations. The second part will present algorithmic advances for solving large scale SDP based on the proximal-point or augmented Lagrangian framework In particular, we describe the design and implementation of an augmented Lagrangian based method (called SDPNAL+) for solving SDP problems with large number of linear constraints. The last part of the talk will focus on recent advances on using a combination of local search methods and convex lifting to solve low-rank factorization models of SP problems.

We introduce a Dimension-Reduced Second-Order Method (DRSOM) for convex and nonconvex (unconstrained) optimization. Under a trust-region-like framework, our method preserves the convergence of the second-order method while using only Hessian-vector products in two directions. Moreover; the computational overhead remains comparable to the first-order such as the gradient descent method. We show that the method has a local super-linear convergence and a global convergence rate of 0(∈-3/2) to satisfy the first-order and second-order conditions under a commonly used approximated Hessian assumption. We further show that this assumption can be removed if we perform one step of the Krylov subspace method at the end of the algorithm, which makes DRSOM the first first-order-type algorithm to achieve this complexity bound. The applicability and performance of DRSOM are exhibited by various computational experiments in logistic regression, L2-Lp minimization, sensor network localization, neural network training, and policy optimization in reinforcement learning. For neural networks, our preliminary implementation seems to gain computational advantages in terms of training accuracy and iteration complexity over state-of-the-art first-order methods including SGD and ADAM. For policy optimization, our experiments show that DRSOM compares favorably with popular policy gradient methods in terms of the effectiveness and robustness.
