Living electronics and fate of plastics

Organic electronics is a rising field, with novel applications including but not limited to stretchable solar cells, flexible display screens, and biosensors. The high performance of these organic electronics is enabled by the outstanding optoelectronic and thermomechanical features of organic semiconducting materials. As the field has progressed, bioelectronics has attracted increasing interest. Bioelectronics, merging manufactured electronics and biology, has emerged as a promising platform for translating electronic signals into ionic ones and vice versa , converting ionic signals into electronic signals ( e. g., biosensors and ionic skins). As a result, in recent years, applications in tissue engineering, drug delivery, electrophoresis and physiology have been developed. As we look into the future of bioelectronics, “living” electronics that merge the synthetic and biological world, holds some interest.

Separate to the above, microplastics composed of various plastic and polymeric materials pose as a major global environmental issue that can cause detrimental consequences to marine organisms and across the food chain. We have been collaborating with researchers at UW to identify microplastics in marine organisms in the Puget Sound and have identified that not all organisms consume the same microplastics.

In both projects, we seek to initiate collaborations with those at OIST and look forward to initiating discussions with various units.

★DISTINGUISHED LECTURE Professor Yoshikazu Giga , The University of Tokyo Title: On a singular limit of a single-well Modica-Mortola functional and its applications Abstract:

It is important to describe the motion of phase boundaries by macroscopic energy in the process of phase transitions. Typical energy describing the phenomena is the van der Waals energy, which is also called a Modica-Mortola functional with a double-well potential or the Allen-Cahn functional. It turns out that it is also important to consider the Modica-Mortola functional with a single-well potential since it is often used in various settings including the Kobayashi-Warren-Carter energy, which is popular in materials science. It is very fundamental to understand the singular limit of such a type of energies as the thickness parameter of a diffuse interface tends to zero. In the case of double-well potentials, such a problem is well-studied and it is formulated, for example, as the Gamma limit under L 1

convergence.

However, if one considers the Modica-Mortola functional, it turns out that L 1

convergence is too rough even in the one-dimensional problem.

We characterize the Gamma limit of a single-well Modica-Mortola functional under the topology which is finer than L 1

topology. In a one-dimensional case, we take the graph convergence. In higher-dimensional cases, it is more involved. As an application, we give an explicit representation of a singular limit of the Kobayashi-Warren-Carter energy. Since the higher-dimensional cases can be reduced to the one-dimensional case by a slicing argument, studying the one-dimensional case is very fundamental. A key idea to study the one-dimensional case is to introduce “an unfolding of a function” by changing an independent variable by the arc-length parameter of its graph. This is based on a joint work with Jun Okamoto (The University of Tokyo), Masaaki Uesaka (The University of Tokyo, Arithmer Inc.), and Koya Sakakibara (Okayama University of Science, RIKEN).

In this talk, we will describe some new ways of characterising Sobolev norms, using sizes of superlevel sets of suitable difference quotients. They provide remedy in certain cases where some critical Gagliardo-Nirenberg interpolation inequalities fail, and lead us to investigate real interpolations of certain fractional Besov spaces. Some connections will be drawn to earlier work by Bourgain, Brezis and Mironescu. Joint work with Haim Brezis, Jean Van Schaftingen, Qingsong Gu, Andreas Seeger and Brian Street.

Notes from Underground: vocal communication in a eusocial rodent

Naked mole-rats are exceptionally long-lived (reported lifespans > 30 years), highly resistant to cancer and low oxygen conditions and live in colonies organized to support a single breeding female, queen. This type of social behavior is rare among mammals, although commonly found in the social insects: bees, wasps, and ants. Yet how naked mole-rats organize and maintain their elaborate social groups is largely unknown. Recent work from our group identified a critical role for vocal communication in naked mole-rats societies. Using machine learning techniques, we developed methods to automatically classify and analyze features of one vocalization type, the soft chirp, a greeting call used by naked mole-rats when they encounter one another in their subterranean habitat. We demonstrated that soft chirps encode information about individual and colony identity, suggesting the possibility of colony specific dialects. In a series of behavioral tests, we found that vocal responses were enhanced to home colony vs. foreign colony audio playbacks and to artificially generated colony-specific dialects. We further demonstrated that these dialects can be learned, as pups that were cross-fostered early in life acquired the dialect of their adoptive colonies. Colony specificity of vocal dialects is controlled in part by the presence of the queen: when the queen was lost the vocal cohesiveness of the colony dialect disintegrated. In this lecture I will highlight some of the remarkable lessons we can learn from the naked mole-rat including how vocal communication emerges as an evolutionary mechanism for enhanced cooperation.

At our next Innovators Society meeting, we will be joined by Dr. Masaru Nagura - General Manager at Cambridge Innovation Center (CIC) Tokyo.

Speaker: Masato Mimura 見村万佐人 (Tohoku University 東北大学)

Talk Title : The Green--Tao theorem for number fields

Abstract: The celebrated Green--Tao theorem states that an upper dense subset of the set of rational primes contains arbitrarily long arithmetic progressions. Later, Tao proved that an upper dense subset of the set of Gaussian primes, namely, prime elements in the integer ring $\mathbb{Z}[\sqrt{-1}]$ of the number field $\mathbb{Q}(\sqrt{-1})$ contains arbitrarily shaped constellations. (We will explain the precise statement in the talk.) In the paper, Tao asked whether the same conclusion holds in the setting of arbitrary number fields. In this joint work with Wataru Kai (Tohoku U.), Akihiro Munemasa (Tohoku U.), Shin-ichiro Seki (Aoyama Gakuin U.) and Kiyoto Yoshino (Tohoku U.), we answer Tao's question in the affirmative. We have an application to the setting of a binary quadratic form. More precisely, given a form $F$, we study combinatorics on the set of pair of integers $(x,y)$ for which $F(x,y)$ is a rational prime. No serious background of number theory is required for this talk.

Part II Diversity Panel Discussion 4-5 pm

Speaker : Professor Mario Bonk, UCLA Title : Fractals and the dynamics of Thurston maps

Abstract:

A Thurston map is a branched covering map on a topological 2-sphere for which the forward orbit of each critical point under iteration is finite. Each such map gives rise to a fractal geometry on its underlying 2-sphere. The study of these maps and their associated fractal structures links diverse areas of mathematics such as dynamical systems, classical conformal analysis, hyperbolic geometry, Teichmüller theory, and analysis on metric spaces. In my talk I will report on some recent developments. Registration: https://oist.zoom.us/meeting/register/tJAtcOGqrDsrE9KqW7_5WOdtPTZ2XEJIqo6-
