Pulmonary Circulation, Volume 3, Issue 4, Page 739-756, December 2013., 2013 Pulmonary hypertension (PH) is a disorder that develops as a result of remodeling of the pulmonary vasculature and is characterized by narrowing/obliteration of small pulmonary arteries, leading to increased mean pulmonary artery pressure and pulmonary vascular resistance. Subsequently, PH increases the right ventricular afterload, which leads to right

Hubble Space Telescope NICMOS Imaging of W3 IRS 5: A Trapezium in the Making?
, 2005 We present Hubble Space Telescope NICMOS imaging of W3 IRS 5, a binary high-mass protostar. In addition to the two protostars, NICMOS images taken in the F222M and F160W filters show three new 2.22 micron sources with very red colors; these sources fall ...

Meteoritics &Planetary Science, Volume 59, Issue 11, Page 3111-3123, November 2024.Abstract A laboratory study was performed using the Visible Oxford Space Environment Goniometer in which the broadband (350–1250 nm) bidirectional reflectance distribution functions (BRDFs) of two representative Apollo regolith samples were measured, for two surface roughness profiles, across a range of viewing angles—reflectance: 0–70°, in steps of 5°;

Signature of Plausible Accreting Supermassive Black Holes in Mrk 261/262 and Mrk 266
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 We address the neutrino radiation of plausible accreting supermassive black holes closely linking to the 5 nuclear components of galaxy samples of Mrk 261/262 and Mrk 266. We predict a time delay before neutrino emission of the same scale as the age of the Universe. The ultrahigh energy neutrinos are produced in superdense protomatter medium via simple

Comment on: Diffusion through a slab
, 1997 Mahan [J. Math. Phys. 36, 6758 (1995)] has calculated the transmission coefficient and angular distribution of particles which enter a thick slab at normal incidence and which diffuse in the slab with linear anisotropic, non-absorbing, scattering.

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.This study investigates plate analyses employing the method of initial functions (MIFs) across various plate geometries and loading conditions. The conclusions derived from thick rectangular plates highlight substantial thickness‐induced effects on deflection and stress distributions.

On the Cosmic Ray‐Induced Ionization Rate in Molecular Clouds
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 The transformation of the energy dependence of the cosmic ray proton flux in the keV to GeV region is investigated theoretically when penetrating inside molecular clouds (Av > 5 mag). The computations suggest that energy losses of the cosmic ray particles by interaction with the matter of the molecular cloud are principally caused by the inelastic ...

, 2010 We investigate the long-term dynamical evolution of star clusters in a steady tidal field produced by its parent galaxy. In this paper, we focus on the influence of mass profile of the parent galaxy. The previous studies were done with the simplification

Free Vibration of Sandwich Plates and Shells by Using Zig‐Zag Function
Shock and Vibration, Volume 16, Issue 5, Page 495-503, 2009., 2009 This paper analyses the free vibration response of sandwich curved and flat panels by introducing the zig‐zag function (—1)kζk (ZZF) in the displacement models of classical and higher order two‐dimensional shell theories. The main advantage of ZZF is the introduction of a discontinuity in the first derivative, zig‐zag effect, of the displacements ...

The Evolution of Wide Binary Stars
, 2009 We study the orbital evolution of wide binary stars in the solar neighborhood due to gravitational perturbations from passing stars. We include the effects of the Galactic tidal field and continue to follow the stars after they become unbound. For a wide
