Abstract Practical assessment of subgrade settlement induced by train operation requires developing suitable models capable describing permanent deformation characteristics filling under repeated dynamic loading. In this paper, load triaxial tests were performed on coarse-grained soil (CGS), and the axial strain CGS different confining pressures stress amplitudes was analysed. Permanent behavio...

OBJECTIVE Leptomeningeal collaterals, which affects tissue fate, are still challenging to assess. Four-dimensional CT angiography (4D CTA) originated from CT perfusion (CTP) provides the possibility of non-invasive and time-resolved assessment of leptomeningeal collateral flow. We sought to develop a comprehensive rating system to integrate the speed and extent of collateral flow on 4D CTA, and...

The efficacy of a neurosurgical navigation system using three-dimensional composite computer graphics (CGs) of magnetic resonance (MR) and computed tomography (CT) images was evaluated in skull base surgery. Three-point transformation was used for integration of MR and CT images. MR and CT image data were obtained with three skin markers placed on the patient's scalp. Volume-rendering manipulat...

The objective of this work is to study the effect of Cu-excess and compare the growth mechanism of CuGaSe2 (CGS) films coevaporated using a bilayer and a three-stage process and evaluate the consequences of the latter for CGS on transparent back contacts. CGS thin films are prepared by coevaporation in a three-stage process onto Mo/soda-lime substrates and onto FTO. In contrast to the bilayer p...

The nature of Compact Groups (CGs) is investigated by comparing luminosity and morphology of CG galaxies, CG Neighbours and Isolated galaxies. CGs turn out to display a clear excess of both E-S0 and bright galaxies with respect to Isolated galaxies. Neighbours exhibit luminosity and morphological content intermediate between Isolated and CG galaxies. Differences between CGs and their surroundin...

The heart is an important target of thyroid hormone actions. Only a limited number of cardiac target genes have been identified, and little is known about their regulation by T(3) (3,3',5-triiodothyronine) and thyroid hormone analogs. We used an oligonucleotide microarray to identify novel cardiac genes regulated by T(3) and two thyroid hormone analogs, 3,5-diidodothyropropionic acid (DITPA) an...

The aim of this study was to investigate the molecular mechanisms underlying drought acclimation in coffee plants by the identification of candidate genes (CGs) using different approaches. The first approach used the data generated during the Brazilian Coffee expressed sequence tag (EST) project to select 13 CGs by an in silico analysis (electronic northern). The second approach was based on sc...

Cystathionine γ-synthase (CGS) is a transulfurication enzyme that catalyzes the first specific step in L-methionine biosynthesis by the reaction of O(4)-succinyl-L-homoserine and L-cysteine to produce L-cystathionine and succinate. Controlling the first step in L-methionine biosythesis, CGS is an excellent potential drug target. Mycobacterium ulcerans is a slow-growing mycobacterium that is the...

Synthetic aperture radar (SAR) images have special physical scattering characteristics owing to their unique imaging mechanism. Traditional deep learning algorithms usually extract features from real-valued SAR in a purely data-driven manner, which may ignore some important and sacrifice useful target information images. This undoubtedly limits the improvement performance for recognition. To ta...

Introduction:Adenosine as a potent vasodilator has physiological role in regulation of regional cerebral blood flow (rCBF). Metod: Laser-Dِoppler flowmetry technique was used to study pial vessels blood flow responses to adenosine receptors agonists and antagonist. Male Sprague Dawley rats (250-350g) that were housed in standard conditions, were anesthetized with Urethane (1.5g/kg). Adenosine ...
