Loss of strength in Ni3Al at elevated temperatures [PDF]
, 2006 Stress decrease above the stress peak temperature (750 K) is studied in h123i single crystals of Ni3(Al, 3 at.% Hf ). Two thermally activated deformation mechanisms are evidenced on the basis of stress relaxation and strain rate change experiments.

Axisymmetric polydimethysiloxane microchannels for in vitro hemodynamic studies [PDF]
, 2009 The current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques,

Elasticities and the Inverse Hyperbolic Sine Transformation
Oxford Bulletin of Economics and Statistics, 2019 Applied econometricians frequently apply the inverse hyperbolic sine (or arcsinh) transformation to a variable because it approximates the natural logarithm of that variable and allows retaining zero‐valued observations.

Infrastructural Speculations: Tactics for Designing and Interrogating Lifeworlds [PDF]
, 2020 This paper introduces “infrastructural speculations,” an orientation toward speculative design that considers the complex and long-lived relationships of technologies with broader systems, beyond moments of immediate invention and design.

Males, masculine honor and witch hunting in seventeenth-century Germany [PDF]
, 2004 This article aims to contribute to the emerging cultural study of early modern witchcraft by examining one particular prosecution from the Bishopric of Bamberg—a territory in Germany that experienced very intensive witch persecutions between 1625 and ...

Focus drive mechanism for the IUE scientific instrument [PDF]
, 1977 A compact, lightweight mechanism was developed for in-orbit adjustment of the position of the secondary mirror (focusing) of the International Ultraviolet Explored telescope. This device is a linear drive with small (.0004 in.) and highly repeatable step

Pattern Formation in Non‐Equilibrium Architected Materials
Advanced Materials Technologies, EarlyView.This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Relativistic Chasles' theorem and the conjugacy classes of the inhomogeneous Lorentz group
, 2013 This work is devoted to the relativistic generalization of Chasles' theorem, namely to the proof that every proper orthochronous isometry of Minkowski spacetime, which sends some point to its chronological future, is generated through the frame ...
