We estimated the luminosity function (LF) of IRAS galaxies in the PSCz catalogue. The faint end of the PSCz LF is slightly steeper than that of the LF derived by Saunders et al. (1990; S90). Using an analytical form for the LF used by S90, we obtain the following parameters: α = 1.23± 0.04, L∗ = (8.85± 1.75)× 108h−2 L⊙, σ = 0.724± 0.010, and φ∗ = (2.34± 0.30)× 10−2h3 Mpc−3. We also examined the...

In many applications in engineering and sciences analysts have simultaneous access to multiple data sources. such cases, the overall cost of acquiring information can be reduced via fusion or multi-fidelity (MF) modeling where one leverages inexpensive low-fidelity (LF) sources reduce reliance on expensive high-fidelity (HF) data. this paper, we employ neural networks (NNs) for scenarios is ver...

An Apollonian configuration of circles is a collection of circles in the plane with disjoint interiors such that the complement of the interiors of the circles consists of curvilinear triangles. One well studied method of forming an Apollonian configuration is to start with three mutually tangent circles and fill a curvilinear triangle with a new circle, then repeat with each newly created curv...

Bacillus anthracis lethal toxin consists of the protective antigen (PA) and the metalloprotease lethal factor (LF). During cellular uptake PA forms pores in membranes of endosomes, and unfolded LF translocates through the pores into the cytosol. We have investigated whether host cell chaperones facilitate translocation of LF and the fusion protein LF(N)DTA. LF(N) mediates uptake of LF(N)DTA int...

Although an association between Lassa fever (LF) and sudden-onset sensorineural hearing loss (SNHL) was confirmed clinically in 1990, the prevalence of LF-induced SNHL in endemic countries is still underestimated. LF, a viral hemorrhagic fever disease caused by Lassa virus (LASV), is endemic in West Africa, causing an estimated 500,000 cases and 5,000 deaths per year. Sudden-onset SNHL, one com...

The earliest JWST observations have revealed an unexpected abundance of super-early ($z>10$), massive ($M_*\approx 10^9\, M_\odot$) galaxies at the bright-end ($M_{\rm UV}\approx -21$) ultraviolet luminosity function (UV LF). We present a minimal physical model that explains observed galaxy $z=10-14$. primarily combines (a) halo mass function, with (b) obscured star formation fraction prescript...

Abstract Background Normotensive premenopausal women show a vagal predominance of cardiac autonomic modulation, whereas age-matched men sympathetic modulation. However, some develop systemic arterial hypertension (SAH) even with preserved ovarian function. Our hypothesis is that these may have cardiovascular parameters similar to those hypertensive men, when subjected pharmacological treatment....
