Speaker： Professor Jiang-Hua Lu（The University of Hong Kong）Venue： 数学科学学院2楼报告厅(海纳苑2幢210室)Abstract： After briefly introducing some basic facts in Poisson geometry, we explain how Poisson geometric considerations naturally lead to cluster mutations as in the theory of cluster algebras. As a special class of examples, we show how the so-called standard Poisson structure on generalized Schubert cells can be used, via the theory of symmetric Poisson CGL extensions developed by K. Goodearl and M. Yakimov, to obtain cluster structures on related varieties from Lie theory.

Doubly selective fading becomes more severe when future communications move to higher frequency bands in the mm-wave or sub-THz range. Multipath fading introduces inter-symbol interference (ISI) in single-carrier communication systems, Doppler spread introduces inter-carrier interference (ICI) to multi-carrier communication. Tracking the fast- varying fading channel states also requires more pilot overhead, which cuts communication efficiency. On the other hand, multipath presents frequency diversity, while Doppler effects present time diversity, which are good against signal deep fades. In this talk, I will share recent results in constructing doppler-resilient multipath receivers with low pilot overhead, by exploiting BEM channel modelling, pseudo-pilot, iterative channel estimation and equalization, and other techniques, turning the foes in doubly selective fading channel to diversity benefits. 

Speaker: Jerome BusemeyerVenue: 537, No.3 Haina BuildingAbstract: Quantum cognition is a growing new field in cognitive science concerned with the application of the mathematical principles of quantum theory to human judgment and decision-making. Essentially, it applies the mathematics of quantum theory without the physics to human behavior. Quantum consciousness concerns both the possible role that quantum mechanics has for understanding consciousness, as well as the other way around, the role that consciousness has for understanding quantum physics. Quantum brain theories hypothesize that quantum physical processes occur within and between the neurons of the brain and have important effects on cognition as well as consciousness. What do all these theories have to do with each other? Past work on quantum cognition has avoided addressing fundamental issues about consciousness and remained agnostic with respect to the quantum brain hypothesis. Quantum theories of consciousness have more to say about quantum physics than cognitive psychology more to say about quantum physics than cognitive psychology and conscious experiences.Quantum brain theories have not been sufficiently "scaled up"to provide clear implications for how quantum physical processes actually generate more complex cognition. During this talk I will address the problem of connecting these ideas together by connecting quantum cognition to the other two topics. First, for the purpose of this talk, let us set aside the arguments, and adopt the premise that the quantum brain hypothesis is correct. What would this imply for quantum cognition? How would this hypothesis change the way quantum cognition researchers do their business (i.e., build their mathematical models of behavior). Second, what if anything,can quantum cognition bring to the discussion of consciousness using only the mathematical principles of quantum theory?

Speaker: Hans Feger (Freie Universität Berlin)Host: Jun WangVenue: Zijingang Campus成均苑4幢哲学学院 Room 429Abstract: 东西方学者在跨文化背景下研究大陆哲学的哲学传统时，有一个显著的趋向，即主张：1、大陆哲学遵循启蒙运动的理性主义传统，并因而敌视自然；2、大陆哲学是欧洲中心主义的，尤其是在人权的普遍性问题上；3、大陆哲学在虚幻的、自律意义上的自由之下其实是自我中心主义的，它只允许人类中心主义的自然观。这些主张似是而非，本讲座将借助康德和谢林的哲学对其加以反驳，并提出一种更为不同的、能够架起一座通向中国哲学之桥梁的阐述。

Speaker: Vinay TERGAONKAR, Department of Pathology and theDepartment of Biochemistry, Yong Loo LinSchool of Medicine, NUSVenue: ZJE科研楼 2A 203-1Abstract: Over 90% of human cancers attain immortality by transcriptional re-activation of an enzyme called telomerase reverse transcriptase (TERT). While human gem and stem cells transcribe TERT, its expression is transcriptionally silenced in all somatic cells. How and why TERT is reactivated in the vast majority of human cancers remain fundamental unsolved problems in biology. l will present unpublished results which will suggest why TERT is reactivated in human cancers. l will also describe a molecular mechanism which explains how genetic and non-genetic factors, like high iron-(Fe3+), from consumption ofred meat, collude to re-activate this enzyme, thereby explaining a long-standing link between red meat and carcinogenesis. l will also describe the identification of a small molecule inhibitor of this molecular pathway that may be developed using medicinal chemistry for therapeutic use in a large proportion of human cancers where iron-Fe3+) is a key driver.

Speaker: Sunil BaldVenue: Lecture Hall, Zhejiang University Museum of Art and Archaeology (ZJUMAA), Zijingang CampusAbstract:Architecture privileges “grounded-ness”— in how it acknowledges gravity and situates itself in ‘place.’ Central to this grounded-ness is a clear connection to context, whether in the working process of the architect or as an ambition to respond to those who inhabit it. However, studioSUMO has explored floating, and consequently “ungrounded-ness,” in both design and practice. In this lecture, Sunil Bald, co-founding partner of studioSUMO, will discuss designing from a distance, whether in time or space, and how this has led the embrace of floating as a tectonic andmetaphysical condition for both the architectural object and architecturapractice.
