Quantitative analysis of SAR signatures require an absolute radiometric calibration of the complete SAR system. The active reflector named as transponder is an effective SAR calibration device that can yield a larger radar cross section than a corner reflector, and decouple the transponder from the background scatterers, which can be used to calibrate the SAR for radiometry, polarimetry, and in...

This work concludes a series of systematic re-examinations of the Raman/Infrared spectra of representative semiconductor alloys in the traditionally admitted classification of phonon mode behaviour, i.e. In1−xGaxAs (1-bond→1-mode), In1−xGaxP (modified 2-mode) and presently ZnTe1−xSex (2-bond→1-mode), based on a crude description of the alloy disorder at the macroscopic scale in terms of the vir...

Arpin is a newly discovered regulator of actin polymerization at the cell leading edge, which steers cell migration by exerting a negative control on the Arp2/3 complex. Arpin proteins have an acidic tail homologous to the acidic motif of the VCA domain of nucleation-promoting factors (NPFs). This tail is predicted to compete with the VCA of NPFs for binding to the Arp2/3 complex, thereby mitig...

Markers of Epstein-Barr virus (EBV) infection include measures of specific serological titers and of viral load (VLo) in peripheral blood mononuclear cells. Few studies have investigated the correlation between these two phenotypes. Here, we found that there was no correlation between VLo and either anti-EBV nuclear antigen type 1 or anti-early antigen immunoglobulin G (IgG) titer but that anti...

Density-functional theory (DFT) based first-principles calculations were used to investigate the crystal structure, binding energy, phase stability and elastic properties of body-centered cubic (BCC) W-based binary solid solutions. The effect alloying up 50 atomic percent (at.%) concentration range is determined from virtual-crystal approximation (VCA) approach. Resulting BCC solutions are asse...

This paper traces the recent turn to humour, irony and ambiguity embodied in adaptation of memes into repertoire online propaganda militant neo-Nazi group Nordic Resistance Movement; a process, we dub ‘memefication’ white supremacism. Drawing on combination quantitative visual content analysis (VCA) in-depth focused iconography symbolism, explore all (N = 634) created circulated by around 2018 ...

INTRODUCTION Astasia is a rare presenting symptom of stroke, usually known as 'thalamic astasia', induced by a lesion in the ventrolateral thalamus. We report a case of caudal cingulate infarction manifesting astasia. CASE PRESENTATION A 58-year-old male presented with inability to sit, stand and walk (astasia). No apparent motor weakness was noticed in the extremities. MRI revealed cerebral ...

BACKGROUND We hypothesized that subset classification of Epstein-Barr virus (EBV) in chronic fatigue syndrome (CFS) is required. At first, a blinded-random placebo-controlled trial of valacyclovir in EBV CFS subset was performed (Group 1), and this EBV subset was followed for thirty-six months (Group 2). Patients were given valacyclovir at 14.3 mg/kg every 6 hours. The validated Energy Index (E...
