Report of iTHEMS Biology Seminar

2019-09-26

iTHEMS Biology Seminar was held on September 13, inviting Prof. Hiroyuki Kubota (Kyushu University) and Dr. Yasufumi Uezu (NTT). The theme of this seminar is “mathematical biology in temporal waveforms.” Prof. Kubota revealed that the temporal patterns of blood insulin concentration selectively regulate downstream molecules depending on network structure and time constant. His discovery is important for understanding the mechanism not only of insulin signaling but also of many signal transduction systems in biology. Dr. Uezu is specialist of voice production research. Textbook in this field often explains vocal fold vibration (sound source) and vocal tract filter are independent. In contrast, he experimentally showed that nonlinear interaction between them is crucial for generating various singing voice, for example falsetto and scream. The seminar attracted a wide range of audience including biologist, physicist, and mathematician, and we enjoyed active discussion.

iTHEMS Colloquium

Topological phases of matter and operator algebras

October 4 (Fri) at 15:30 - 17:00, 2019

Yasuyuki Kawahigashi (Senior Visiting Scientist, iTHEMS / Professor, Graduate School of Mathematical Sciences, The University of Tokyo)

Topological phases of matter are hot topics in recent physics and related to a wide range of mathematical fields. I will talk about their aspects related to operator algebras. Our emphasis will be on theory of tensor categories which describe interactions of anyons. This theory plays an important role in topological quantum computations.
In theory of operator algebras, Jones initiated theory of subfactors and discovered the Jones polynomial, a new topological invariant for knots as an application. We apply this theory to mathematical studies of anyons.

Workshop

Workshop on Virtual Reality［Session 1］

October 7 (Mon) at 13:00 - 16:00, 2019

Gilles Ferrand and Don Warren will run a workshop on using virtual reality (VR) for data visualization and research. Anyone from any RIKEN campus, and any field of study, is welcome. We want to build a cross-disciplinary group of people with a shared interest in VR, and to apply this tool to a broad range of data types and topics.
