Speaker: SHEN JieVenue: Lecture Hall 206, Haina Complex Building, Zijingang CampusAbstract: Many complex nonlinear systems have intrinsic structures such as energy dissipation or conservation, and/or positivity/maximum principle preserving. It is desirable, sometimes necessary, to preserve these structures in a numerical scheme. I will present some recent advances on using the scalar auxiliary variable (SAV) approach and Lagrange multiplier approach to develop highly efficient and accurate structure preserving schemes for a large class of complex nonlinear systems.These schemes can preserve energy dissipation/conservation as well as other global constraints and/or are positivity/bound preserving, only require solving decoupled linear equations with constant coefficients at each time step and can achieve higher-order accuracy.

Speaker: Mike RobinsonVenue: Research and Study Space, 3rd Floor, Humanities Building, Xixi CampusAbstract: Under the framework of United Nations sustainable development, World Heritage sites must not only achieve their own sustainability but also contribute to broader social well-being. However, in practice, the implementation of these goals has posed numerous challenges and dilemmas for heritage site management. This report will use case studies to illustrate how heritage management requires greater creativity and innovation, even though certain approaches remain controversial.

Speaker: Dr. Tom PegramAbstract: This lecture will examine the role of crisis in global governance, its evolving concept and impact on IR scholarship. It will address the ambiguity of the crisis concept, seen in terms like “permacrisis” and “polycrisis,” and its use in various contexts such as financial instability and climate change. The lecture will introduce a distinction between conjunctural and structural crises, using the 2008 financial crisis and ongoing climate crisis as examples. It will show how different crisis framings affect institutional responses and our understanding of stability and change in global governance. Finally, it will encourage IR scholars to reflect on crisis as an analytical tool and pay more attention to the political and normative aspects of crisis discourse.

Speaker: Xiaochun RongVenue: Lecture Hall 210, Haina Complex Building 2, Zijingang CampusAbstract: Fixing E> 0, a complete Riemannian n-manifold M is called E-collapsed, if every unit ball in M has a volume <E. In Riemannian geometry, interplays between a collapsing geometry and topology has been an important component, and complexities in topology of a collapsed M is linked to a bound on curvature. Around 1980-2000, collapsedmanifolds of bounded sectional curvature was intensively studied by Cheeger-Fukaya-Gromov and many others, which has found several applications. In this talk, we will survey a development in the last decade in investigating collapsed manifolds of Ricci curvatureb ounded below and universal covering of every unit ball in M is not collapsed.

Speaker: TIAN KoumaoVenue: 4-311, Chengjun Court, Zijingang CampusAbstract: There is an argument that the ‘mind’ of another person is not hidden inside the skull, but is ‘seen’ directly in the body’s behavior and interaction with others. This is called ‘direct social perception’ (DSP), a concept proposed in the field of phenomenology. Based on this idea, if AI and robots can achieve behavior indistinguishable from that of humans (beyond a certain level), we are forced to see a ‘subject’ with whom we can interact. In this talk, I will point to the passive generation of an enactive intersubjective loop as the condition that makes DSP possible, and argue that this level diverges from the level of active reasoning when interacting with AI. Then, I believe that artificial life-like ‘fragility’ and ‘precariousness’ are necessary for the interaction with artificial subjects to go one step deeper. Finally, I will consider the future of coexistence with AI, distinguishing between the future in which fragile life-like AI incorporating ‘death’ is born and the future in which it is not.

Speaker: Minghua ChenVenue: 418, Teaching Building No.4, Yuquan CampusAbstract: The Optimal Power Flow (OPF) problem aims to minimize power generation costs while meeting grid demand and adhering to physical constraints, serving as a pivotal challenge in power system operations, its applications span electricity markets, reliability assessments, and grid modernization for carbon neutrality, with global annual operational costs reaching billions of USD. Traditional iterative solvers struggle with large-scale OPF due to its non-convex and NP hard nature.Recent advances in machine learning (ML)have accelerated OPF solutions by orders of magnitude through techniques like constraint classification, warm-start solutions, and direct load-to-solution mapping, while maintaining accuracy.This tutorial explores cutting-edge ML applications in OPF, including active constraint identification, solver strategy learning, and cross-domain optimization generalization.Future directions for enhancing computational efficiency and robustness under increasing renewable energy uncertainty are also discussed.

Venue: Lecture Hall, ZJU Museum of Art and Archaeology, Zijingang CampusSpeaker: Alba Di LietoProfessor Di Lieto served as executive architect for the City Museums of Verona, Italy, until 2022, where she was responsible for exhibition design and the Carlo Scarpa Archive. She has also collaborated on the restoration, conservation, and design of Verona’s museums, including the Archaeological Museum at the Roman Theater, the Towers of Castelvecchio, and the new wing and the garden of the Frescoes Museum “G.B. Cavalcaselle at Juliet's Tomb. Around the 1960s, the Venetian architect, Carlo Scarpa (1906-1978) carried out an innovative critical restoration of the monument, creating a spectacular exhibition design integrated and in continuity the museum's fine art collection. His museographical approach has since inspired contemporary artists and architects such as the American Peter Eisenmann, the German Herbert Hamak, the Polish Igor Mitoraj, and the Italians Maria Morganti and Giorgio Vigna. This lecture will be based on Professor Di Lieto`s direct experience during her service at the City Museums of Verona, Italy. Since the Eighties, she has collaborated with artists and architects on numerous exhibitions, many of which have been realized inside the Castelvecchio Museum, as well as in its garden. The talk titled “The Continuity of Exhibit-Design in the Castelvecchio Museum, (or in the City Museums) in Verona-Italy” explores the results of these experimental projects. Each site-specific art installation, despite its unique character, is conceived through the lens of Scarpa's design language, achieving a new balance between space, objects and innovative display solutions.
