Properties of selective-area-grown (SAG) ternary and quaternary layers of InGaAs and InGaAsP produced by metal organic vapor phase epitaxy (MOVPE) have been investigated by using a combination of micro-photoluminescence and synchrotron-based micro-beam X-ray fluorescence techniques. Significant variations of the group-III element composition with increase of the oxide mask width and with decrea...

â â â  chele basin is located in zagros mountains and the border between kermanshah and ilam. seems young geomorphological landforms in the region, are as a result of quaternary neotectonic activities . the purpose of this study is assessment of young morphotectonic movements influence on landform evolution in the chele basin øŒ and comparing the result with the tentative indices and geomorphic...

A 1-perfect code Cn q is called Hamiltonian if its minimum distance graph G(Cn q ) contains a Hamiltonian cycle. In this paper, for all admissible lengths n ≥ 13, we construct Hamiltonian nonlinear ternary 1-perfect codes, and for all admissible lengths n ≥ 21, we construct Hamiltonian nonlinear quaternary 1-perfect codes. The existence of Hamiltonian nonlinear q-ary 1-perfect codes of length N...

abstract the study of natural disasters is one of the most important primary principles for the growth of developing cities and the development of infrastructures. to this end, evaluating geodynamic activities using morphological data is considered one of the most pivotal applied methods. in this study, it was tried to detect active faults in yazd province using desert studies and remote sensin...

SNAP receptor (SNARE) complexes bridge opposing membranes to promote membrane fusion within the secretory and endosomal pathways. Because only the exocytic SNARE complexes have been characterized in detail, the structural features shared by SNARE complexes from different fusion steps are not known. We now describe the subunit structure, assembly, and regulation of a quaternary SNARE complex, wh...

We construct a large number of record-breaking binary, ternary and quaternary codes. Our methods involve the study of BCH-codes over larger fields, concatenation, construction X and variants of the Griesmer construction (residual codes). 1 Review of the theory Let IFq be the ground field, F = IFq2 . Denote the interval {i, i + 1, . . . , j} ⊂ ZZ/(q−1)ZZ by [i, j]. Let A = [i, j] ⊂ ZZ/(q−1)ZZ. I...

In specific geological contexts, such as alluvial environments, the lithology is highly heterogeneous and laterally variable. As a result, a large number of lithological data are collected (generally random and under sampled) for stratigraphic reconstruction. The integrated management of geo-lithologic data causes major methodological problems, because data obtained from geognostic investigatio...

Background & Aim: Q fever is an important zoonotic disease caused by infection with Coxiella burnetii, a Gram negative, obligate intracellular bacterium classified within the order Legionellales. Farmers, veterinarians, abattoir workers and laboratory personnel are among persons at risk of Q fever. The aim of this study was to determine frequency of IgM anti-Coxiella burnetii antibodies in slau...

Alborz Mountains is a region of active deformation within Arabia-Eurasia collision zone. The study fault system in western Alborz comprises abundant evidence of active faulting accompanied by occurrence of historical earthquakes. Active tectonics of Manjil-Rudbar fault zone whose movement caused destructive 1990 Manjil-Rudbar earthquake was concentrated in this article through geomorphic and st...
