Commentary

Ronald J. Tabak, Chair of the Committee on the Death Penalty for the American Bar Association\u27s Section of Individual Rights and Responsibilities, discusses the Section\u27s purpose in organizing Forhdam University School of Law\u27s panel discussion on Politics and the Death Penalty. The goal was to illuminate the variety of effects of a widespread perception that the belief of legislators, governors, prosecutors, judges, clemency boards, political candidates and others that the public is overwhelmingly in support of capital punishment. The Section aimed to bring together knowledgeable people from a variety of perspectives to discuss (a) how the capital punishment system and the political process have been affected by the perceived overwhelming popular support for the death penalty, (b) the role that reportage - or the lack thereof - has had on public attitudes about the death penalty and (c) whether opponents of capital punishment can survive politically. Taback then gives an overview of what was discussed by each panelist, which included Norman Redlich, former Dean of New York University Law School, James Coleman, Shabata Sundiata Waglini, Attorney General Ernest Preate, Jr., Bryan Stevenson, Executive Director of the Alabama Capital Representation Resource Center, journalist Nat Hentoff, New York State Assemblywoman Susan John, and Chief Justice Exum of the North Carolina Supreme Court discuss the issue of the death penalty in America

Systematic Stochastic Reduction of Inertial Fluid-Structure Interactions subject to Thermal Fluctuations

We present analysis for the reduction of an inertial description of fluid-structure interactions subject to thermal fluctuations. We show how the viscous coupling between the immersed structures and the fluid can be simplified in the regime where this coupling becomes increasingly strong. Many descriptions in fluid mechanics and in the formulation of computational methods account for fluid-structure interactions through viscous drag terms to transfer momentum from the fluid to immersed structures. In the inertial regime, this coupling often introduces a prohibitively small time-scale into the temporal dynamics of the fluid-structure system. This is further exacerbated in the presence of thermal fluctuations. We discuss here a systematic reduction technique for the full inertial equations to obtain a simplified description where this coupling term is eliminated. This approach also accounts for the effective stochastic equations for the fluid-structure dynamics. The analysis is based on use of the Infinitesmal Generator of the SPDEs and a singular perturbation analysis of the Backward Kolomogorov PDEs. We also discuss the physical motivations and interpretation of the obtained reduced description of the fluid-structure system. Working paper currently under revision.

A serious game for COPD patients to perform physiotherapeutic exercises

The goal of this research was 1) to investigate the usability of the Orange Submarine game, and 2) to explore the changes in saturation and pulse rate in COPD patients while playing the game. The game was positively received by the patients and could provide a new fun way for performing exercises, either at home or as part of the regular treatment

On the thermal behaviour of small iron grains

The optical properties of small spherical iron grains are derived using a Kramers-Kronig-consistent model of the dielectric function including its dependence on temperature and size. Especially discussed is the effect of the size dependence, which results from the limitation of the free path of the free electrons in the metal by the size of the grain, on the absorption behaviour of small iron spheres and spheroids. The estimated absorption properties are applied to study the temperature behaviour of spherical and spheroidal grains which are heated by the interstellar radiation field.Comment: 12 pages, 16 figure
