Display systems are key components of the digital radiology department. Current display systems for medical imaging are based on cathode-ray tubes (CRTs) or active-matrix liquid crystal displays (AMLCDs). The CRT is a cathodoluminescent display: Light is generated by exciting a luminescent material with energetic electrons. AMLCDs are light-modulating devices that form the image in the screen b...

Statement of the problem. Euphemisms neutralize social discourse softening negative impact taboo topics that can cause public disapproval and anxiety. At present, military-political euphemisms are widely used in Russian media which known for their manipulativeness tendency to double standards, with help truth what is happening deliberately hidden. The purpose article analyze euphemism speech st...

Abstract Stars collect most of their mass during the protostellar stage, yet accretion luminosity and stellar parameters, which are needed to compute rate, poorly constrained for youngest sources. The aim this work is fill gap, computing properties rates a large sample Class I protostars located in nearby (<500 pc) star-forming regions analyzing interplay. We used self-consistent method prov...

IRAS04325+2402C is a low luminosity object located near a protostar in Taurus. We present new spatially-resolved mm observations, near-infrared spectroscopy, and Spitzer photometry that improve the constraints on the nature of this source. The object is clearly detected in our 1.3mm interferometry map, allowing us to estimate the mass in a localized disk+envelope around it to be in the range of...

We present new optical, near-IR, and mid-IR observations of the young eruptive variable star V1647 Orionis that went into outburst in late 2004 for approximately two years. Our observations were taken one year after the star had faded to its pre-outburst optical brightness and show that V1647 Ori is still actively accreting circumstellar material. We compare and contrast these data with existin...

A biometry-based human eye model was developed by using the empirical anatomic and optical data of ocular parameters. The gradient refractive index of the crystalline lens was modeled by concentric conicoid isoindical surfaces and was adaptive to accommodation and age. The chromatic dispersion of ocular media was described by Cauchy equations. The intraocular scattering model was composed of vo...

We report optical and infrared imaging spectroscopy observations of the young binary object σ Orionis IRS1 A/B. The brighter component (σ Ori IRS1 A) of this binary system has M1 spectral type and a mass in the range of ≈ 0.3 – 0.8 M⊙. The fainter component (σ Ori IRS1 B) has a unique morphology and spectrum. The unresolved stellar object is surrounded by an extended envelope that is slightly o...

BACKGROUND To inform cost-effective decisions in purchasing new medical liquid crystal displays, we compared the image quality in displays made by three manufacturers. METHODS We recruited 19 radiologists and residents to compare the image quality of four liquid crystal displays, including 3-megapixel Barco(®), Eizo(®), and NEC(®) displays and a 6-megapixel Barco display. The evaluators were ...

This article explores the manifold lineages of crisis and revolt currently afflicting Islamic Republic Iran, most recently bursting forth in 2022/2023 national uprisings where women-led mass protests forceful rejection mandatory veiling laws captured global attention. interdisciplinary piece research, bringing together several different theoretical approaches historical literatures, interrogate...
