Proceedings of the National Academy of Sciences, 2007 Failures of government policies often provoke opposite reactions from citizens; some call for a reversal of the policy, whereas others favor its continuation in stronger form. We offer an explanation of such polarization, based on a natural bimodality of preferences in political and economic contexts and consistent with Bayesian rationality.

Multi-band spin-selective transmission and reflection in bi-layer T-shaped metamaterial
Results in Physics, 2023 The control of the spin angular momentum of light plays an irreplaceable role in modern photon applications. In this work, we proposed a chiral metamaterial based on a bi-layer T-shaped structure.

Journal of Linguistics, 2018 How do people answer polar questions? In this fourteen-language study of answers to questions in conversation, we compare the two main strategies; first, interjection-type answers such asuh-huh(or equivalentsyes,mm, head nods, etc.), and second, repetition-type answers that repeat some or all of the question.

IEEE Photonics Journal, 2019 Liquid-filled hollow core Bragg fibers (HCBFs) provide an excellent platform for refractive index (RI) sensing. The capacity for high-RI sensing based on higher order bandgaps of an HCBF is explored for higher sensitivity.

Journal of Algebra, 2003 The purpose of this paper is to study finite-dimensional Lie algebras over a field k of characteristic zero which admit a commutative polarization (CP). Among the many results and examples, it is shown that, if k is algebraically closed, the nilradical N of a parabolic subalgebra in A_n and C_n has such a CP.

Design of Hollow Core Bragg Fibers for a Compact Fluorescence Sensing Scheme
IEEE Photonics Journal, 2017 We propose a compact fluorescence sensing scheme based on hollow core Bragg fibers (HCBFs) that simultaneously serve as a sample cell, a collector, and a delivery channel for the desired fluorescence, as well as a filter for the residual excitation light

Cell Polarity: The importance of being polar [PDF]
Current Biology, 1995 Cell polarization is often accompanied by cytoskeletal rearrangements. Two signalling proteins, a GTPase and a kinase, are required for both actin and microtubule rearrangements. Are these two systems coupled?
