The Mycobacterium avium complex (MAC), an intracellular pathogen of cells of the macrophage lineage, often clinically coexists with human immunodeficiency virus type 1 (HIV). It was shown previously that coinfection of the monocytoid cell line U937 with HIV and MAC results in the enhancement of HIV replication. To determine whether MAC-mediated HIV upregulation is due to the exposure of intact ...

In this study, idealized simulations of squall line traversing a bell-shape mountain in a three-dimensional framework are conducted using the Weather Research and Forecasting (WRF) model, version 3.2.0, with 2-km horizontal grid size and 60 vertically stretched layers. Water vapor and condensate budgets are examined, and the temporal variations of four microphysics ratios, including precipitati...

From an image we construct an invertible orientation score, which provides an overview of local orientations in an image. This orientation score is a function on the group SE(2) of both positions and orientations. It allows us to diffuse along multiple local line segments in an image. The transformation from image to orientation score amounts to convolutions with an oriented kernel rotated at m...

There is observational evidence showing that stellar and solar flares occur in a similar circumstance, although the former are usually much more energetic. It is expected that the bombardment by high energy electrons is one of the chief heating processes of the flaring atmosphere. In this paper we study how a precipitating electron beam can influence the line profiles of Lyα, Hα, Ca ii K and λ8...

Abstract INTRODUCTION Multiply recurrent glioblastoma suffers from poor response rates to treatment, and limited durability. We describe a case of an impressive third-line CCNU/TMZ. BACKGROUND Headaches brought 76-year-old man medical attention. MRI identified enhancing right temporal mass -- path following resection demonstrated (IDH-wildtype, MGMT-methylated, TERT mutant; PTEN Y68H, CDKN2A/B ...

In this paper, we discuss atomic processes modifying the soft X-ray spectra in from optical depth effects like photoelectric absorption and electron scattering suppressing lines. We also show enhancement line intensities a photoionized environment via continuum pumping. quantify suppression/enhancement by introducing "line modification factor ($f_{\rm mod}$)." If 0 $\leq$ $f_{\rm mod}$ 1, is su...

The technique of velocity modulation spectroscopy has recently been combined with cavity enhancement and frequency modulation methods into a technique called noise-immune cavity-enhanced optical heterodyne velocity modulation spectroscopy (NICE-OHVMS). We have implemented NICE-OHVMS with a cw-optical parametric oscillator (OPO) tunable from 3.2 to 3.9 lm, and used it to record spectra of the R(...

Periodogram smoothing of the received noisy signal is a challenging problem in speech enhancement. We present a Bayesian approach, where the instantaneous periodogram is smoothed through an adaptive smoothing parameter. By updating sufficient statistics using new samples of the noisy signal, the smoothing parameter is adjusted on-line. The performance of the novel smoothing algorithm is studied...

A three-dimensional (3D) electrodynamic model is built using the finite-difference time-domain (FDTD) method to investigate the optical response of carbon nanotubes grafted with gold nanoparticles. Theoretical characterizations suggest an anisotropic response, in line with previously observed absorption peaks of such systems in the optical range. An investigation of geometric and wavelength dep...
