We investigate the role of galaxy mergers on supermassive black hole (SMBH) accretion and star formation quenching in three state-of-the-art cosmological simulations with contrasting physics models: EAGLE, Illustris IllustrisTNG. find that recently coalesced 'post-mergers' all have elevated SMBH rates by factors ~2-5. However, rapid (within 500 Myr coalescence) is rare, incidence 0.4% Illustris...

The variation in visual acuity with illumination has been studied by monitoring the extracellular response of direction sensitive motion detecting neurons to a drifting sine wave grating displayed upon an oscilloscope spreen. Acuity reaches a maximum value of 0.46 cycles/degree at luminances above 1.0 cd/m2 and decreases gradually over a 3.8 log unit attenuation in intensity to a minimum value ...

For the carrion-feeding blow flies, a common source of vitellogenic protein are the carcasses that also serve as larval substrates. This attraction continues well after the blow flies have ceased to oviposit on the carrion, and it has been assumed that a decomposed cadaver remains a suitable source for vitellogenic protein; however, this assumption has never been tested. To test this hypothesis...

BACKGROUND The aim of his study was to determine development time and thermal requirements of three myiasis flies including Chrysomya albiceps, Lucilia sericata, and Sarcophaga sp. METHODS Rate of development (ROD) and accumulated degree day (ADD) of three important forensic flies in Iran, Chrysomya albiceps, Lucilia sericata, and Sarcophaga sp. by rearing individuals under a single constant ...

Defensins are the most widespread antimicrobial peptides characterised in insects. These cyclic peptides, 4-6 kDa in size, are folded into α-helical/β-sheet mixed structures and have a common conserved motif of three intramolecular disulfide bridges with a Cys1-Cys4, Cys2-Cys5 and Cys3-Cys6 connectivity. They have the ability to kill especially Gram-positive bacteria and some fungi, but Gram-ne...

ABSTRACT We present radial gas-phase metallicity profiles, gradients, and break radii at redshift z = 0–3 from the TNG50-1 star-forming galaxy population. These profiles are characterized by an emphasis on identifying steep inner gradient flat outer gradient. From this, radius, Rbreak, is defined as region where transition occurs. observe radius having a positive trend with mass that weakens re...

A year-long entomological survey was performed in 2016-2017 using carrion-baited traps (chicken, pork, squid, or beef) to assess the diversity of necrophagous flies municipality Yautepec, Morelos, Mexico. total 4,765 from 18 families were collected, more than 50 percent specimens collected (2,644) belonged Calliphoridae represented by five genera and eight species. Out these species we evaluate...
