Job Loss and Effects on Firms and Workers [PDF]
, 2011 This paper serves as an introduction and (incomplete) survey of the wide-ranging literature on job loss. We begin with a discussion of job stability in the US and the commitment between firms and workers, and how this has changed in recent years.

Hilbert Expansion from the Boltzmann equation to relativistic Fluids [PDF]
, 2010 We study the local-in-time hydrodynamic limit of the relativistic Boltzmann equation using a Hilbert expansion. More specifically, we prove the existence of local solutions to the relativistic Boltzmann equation that are nearby the local relativistic ...

Mechanically Strained Strained-Si NMOSFETs [PDF]
IEEE Electron Device Letters, 2004 The drain-current enhancement of the mechanically strained strained-Si NMOSFET device is investigated for the first time. The improvements of the drain current are found to be /spl sim/3.4% and /spl sim/6.5% for the strained-Si and control Si devices, respectively, with the channel length of 25 /spl mu/m at the external biaxial tensile strain of 0.037%,

Momentum Regularity and Stability of the Relativistic Vlasov-Maxwell-Boltzmann System
, 2011 In the study of solutions to the relativistic Boltzmann equation, their regularity with respect to the momentum variables has been an outstanding question, even local in time, due to the initially unexpected growth in the post-collisional momentum ...

New design of electrostatic mirror actuators for application in high-precision interferometry [PDF]
, 2015 We describe a new geometry for electrostatic actuators to be used in sensitive laser interferometers, suited for prototype and table top experiments related to gravitational wave detection with mirrors of 100 g or less.
