Plastic deformation and rate-controlling mechanism during tensile of various body-centered cubic (BCC) medium/high-entropy alloys (MEAs/HEAs) were investigated at 300 K. Microstructural observations revealed long, straight screw dislocations, occasionally consisting jogs. The deformed substructures consistent with the evaluated activation volume (V*) indicating dislocation motion overcoming Pei...

Reflection and self-regulated learning are important skills for college level students to learn. We have developed Model Eliciting Activities (MEAs) to integrate these activities while teaching students engineering concepts. A multi-tier design approach is used with MEAs as an element of change for students, instructors and researchers. Three generations of reflection !""#$%&'()%)("#()*%!"%*"+,...

Abstract In recent years, proton exchange membrane (PEM) fuel cells have regained worldwide attention from academia, industries, investors, and governments. The prospect of PEM has turned into reality, with cell vehicles successfully launched in the market. However, today’s remain less competitive than combustion engines batteries, primarily due to their high cost short lifetime, which are sign...

Microelectrode array (MEA) technology is a widely used platform for the study of in vitro neural networks as it can either record or stimulate neurons by accessing multiple sites of neural circuits simultaneously. Unlike intracellular recording techniques, MEAs form noninvasive interface with cells so that they provides relatively long time window for studying neural circuits. As the technology...

Microelectrode arrays (MEAs) are widely used tools for recording and stimulating extracellular neuronal activity. Major limitations when decreasing electrode size in dense arrays are increased noise level and low charge injection capability. Nanostructuration of the electrode sites on MEAs presents an efficient way to overcome these problems by decreasing the impedance of the electrode/solution...

A finite phase-coherence time τ meas φ emerges from iterative measurement onto a quantum system. For a rapid sequence, the phase-coherence time is found explicitly. For the stationary charge conduction problem, it is bounded. At all order, in the time-interval of measurements, we propose a general expression for τ meas φ. PACS: 73.23.-b Mesoscopic Systems 72.15.-v Electronic conduction in metal...

The Atwater energy equivalents of 16.7, 16.7 and 37.7 kJ/g of protein, carbohydrate and fat, respectively, are the standard values used to calculate the macronutrient intakes required to meet a person's metabolizable energy requirement. The aim of this study was to compare in older people the measured metabolizable energy intake (MEI(MEAS)) required to achieve and maintain stable body weights w...

We have assessed how variation in the matrix of control materials would affect error detection and false-rejection characteristics of quality-control (QC) procedures used to monitor PO2 in blood gas measurements. To determine the expected QC performance, we generated power curves for S(mat)/S(meas) ratios of 0.0-4.0. These curves were used to estimate the probabilities of rejecting analytical r...

The information deviation between any two nite measures cannot be increased by any statistical operations (Markov morphisms). It is invariant if and only if the morphism is suucient for these two measures. AMS 1991 Classiication: Primary 62B10 (stat info); Secondary 62B20 (meas th), 62B05 (suu stat), 94A17 (meas of info). Acknowledgment: I thank Kim Sau Chung for pointing out several inaccuraci...

A Model-Eliciting Activity (MEA) presents student teams with a thought-revealing, modeleliciting, open-ended, realistic, client-driven problem for resolution. Here we extend the original MEA construct developed by mathematics education researchers to upper-level engineering coursework and introduce an ethical component. Our extensions also require students to integrate previously learned concep...
