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.

Biosensors, 2022 In this paper, we propose a smartphone-based biosensor for detecting human total hemoglobin concentration in vivo with high accuracy. Compared to the existing biosensors used to measure hemoglobin concentration, the smartphone-based sensor utilizes the ...

Probing the Circular Polarization of Relativistic Jets on VLBI Scales [PDF]
, 2002 High resolution studies of circular polarization allow us see where it arises in a jet, study its local fractional level and spectrum, and compare these results to local measures of linear polarization and Faraday rotation.

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.

The structure of electronic polarization and its strain dependence
, 2008 The $\phi(\kpp)\sim \kpp$ relation is called polarization structure. By density functional calculations, we study the polarization structure in ferroelectric perovskite PbTiO$_3$, revealing (1) the $\kpp$ point that contributes most to the electronic ...

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

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.

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?
