This paper shows that, contrary to their favourable effect in the EU non-FCC (Former Communist Countries), fiscal rules do not significantly affect performance group of FCC. finding, which may echo differences between FCC and other inherited from Cold War period, is robust when considering various estimation methods, dividing along dimensions, using several observed computed measures performanc...
Structures of carbon supported Pt-Ru catalyst in a polymer-electrolyte-fuel-cell (PEFC) were analyzed by X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAFS). XRD analysis identified a face-centered-cubic (fcc) alloy structure for Pt-Ru. XAFS analysis revealed that Pt and Ru atoms were, however, not randomly distributed in the Pt-Ru fcc lattice. A Pt atom was more likely surrounded ...
In UWB systems three factors have to be considered to design a radio link: (i) peakand (ii) average power limits defined by FCC Regulations and (iii) low supply voltage available in handheld cheap devices. An exact mathematical model for the interpretation of FCC Regulations is derived. The radio coverage of UWB networking devices is determined and a chaos-based approach for the coverage extens...
A quasi-sd4 hybridization state for group VIIIB and IB face-centered cubic (FCC) transition metals in low-dimensional nanostructures is identified, in contrast to the sd5 hybridization state in bulk. For Au, a novel three-shelled nanowire is designed with a hexagonal close-packed core in the sd5 hybridization, wrapped by FCC-(111) shell that adopts the quasi-sd4 hybridization. This new nanostru...
عنصر کربن شامل آلوتروپ های گرافیت، الماس و کرباین است. اخیراً در آزمایش های مختلفی ساختاری بلوری از عنصر کربن مشاهده شده که با دیگر ساختارهای کربنی متفاوت است. در مورد نوع ساختار این فاز جدید کربنی که n-diamond نامیده شده اتفاق نظر وجود ندارد. اولین بار ژارکوف و پالاتنیک پیشنهاد کردند که این فاز، یک ساختار fcc از کربن است. از آنجایی که ساختار n-diamond یک ساختار فراپایدار است، موریتا و همکارانش ...
We trace with high numerical accuracy the phase diagram of the Gaussian-core model, a classical system of point particles interacting via a Gaussian-shaped, purely repulsive potential. This model, which provides a reliable qualitative description of the thermal behavior of interpenetrable globular polymers, is known to exhibit a polymorphic fcc-bcc transition at low densities and reentrant melt...
This study investigated the psychoanalytic hypothesis that intensity of the female castration complex (FCC) is greater in women with a masculine social role than in those with a feminine social role. Ss were normal, collegeeducated women, ages 30-55, divided into 2 groups: 26 career women (CW), unmarried, and in masculine occupations; and 25 homemakers, married, with 2 or more children, and not...
Ab initio protein structure prediction is an important problem for which several algorithms have been developed. Algorithms differ by how they represent 3D protein conformations (on-lattice, off-lattice, coarse-grain or fine-grain model), by the energy model they consider, and whether they are heuristic or exact algorithms. This paper presents a local search algorithm to find the native state f...
On Sluggish Diffusion in Fcc Al–Co–Cr–Fe–Ni High-Entropy Alloys: An Experimental and Numerical Study
High-throughput measurement using the numerical inverse method combined with the diffusion multiple technique was employed to determine the composition-dependent interdiffusion coefficients in fcc Al–Co–Cr–Fe–Ni high-entropy alloys at 1273, 1323, and 1373 K. The reliability of the obtained interdiffusion coefficients was confirmed by comparing the model-predicted composition/interdiffusion flux...
