Pseudomonas fluorescens F113 is a plant growth-promoting rhizobacterium (PGPR) that has biocontrol activity against fungal pathogens and model for rhizosphere colonization. Here, we present its complete genome sequence, which shows besides core very similar to those of other strains sequenced within this species, possesses wide array genes encoding specialized functions thriving in the interacting with eukaryotic organisms.
A study of the dead layer thickness and quenching factor a plastic scintillator for use in ultracold neutron (UCN) experiments is described. Alpha spectroscopy was used to determine thin surface be 630 ± 110 nm. The relative light outputs from decay 241Am Compton scattering electrons were extract Birks’ law coefficient, yielding kB value 0.087 0.003 mm/MeV, consistent with some previous reports other polystyrene-based scintillators. results these measurements are incorporated into simulation...
The upcoming UCNProBe experiment at Los Alamos National Laboratory will measure the $\beta$-decay rate of free neutrons with different systematic uncertainties than previous beam-based neutron lifetime experiments. We have developed a new $^{10}$B-coated YAP:Ce scintillator whose properties are presented. advantage is its high Fermi potential, which reduces probability for upscattering ultracold neutrons, and short decay time, important counting rates. Birks' coefficient was measured to be...
The upcoming UCNProBe experiment at Los Alamos National Laboratory will measure the beta decay rate of free neutrons with different systematic uncertainties than previous beam-based neutron lifetime experiments. We have tested a new 10B-coated Yttrium Aluminum Perovskite (YAP:Ce) scintillator and present its properties. advantages YAP:Ce include high Fermi potential, which reduces probability for upscattering ultracold (UCN), short time, increases sensitivity counting rates. Birks’...
A study of the dead layer thickness and quenching factor a plastic scintillator for use in ultracold neutron (UCN) experiments is described. Alpha spectroscopy was used to determine thin surface layer, relative light outputs from decay $^{241}$Am Compton scattering electrons were extract parameter. With these characteristics material known, yield can be calculated. The ability make scintillators deuterated, accompanied by its relatively it ideal UCN experiment, where alphas capture are...
The future Electron-Ion Collider (EIC) will utilize a series of high-luminosity high-energy electron+proton ($e+p$) and electron+nucleus ($e+A$) collisions to explore the inner structure nucleon nucleus matter formation process. Heavy flavor hadron jet measurements at EIC play an essential role in determining nucleon/nucleus parton distribution function heavy quark hadronization process not well constrained kinematic regions. A high granularity low material budget forward silicon tracker...
