High throughput DNA sequencing in combination with efficient algorithms could provide the basis for a highly resolved, genome phylogeny-based and digital prokaryotic taxonomy. However, current taxonomic practice continues to rely on cumbersome journal publications description of new species, which still constitute smallest units. In response, we introduce LINbase, web server that allows users genomically circumscribe any group prokaryotes measurable similarity uses individual isolate as...
Abstract The performance of a new compact (55 cm × 56 48 cm) in-situ spin-exchange optical pumping (SEOP) 3 He-neutron spin filter (NSF) system developed at the China Spallation Neutron Source (CSNS) is presented. enclosed NSF cell, filled with 2.53 bar He, was born He polarization around 60%. After subsequent improvements to magnetic field and heating system, this able achieve 75.66%±0.09% polarization, resulting in 96.30% neutron 2 Å. This highly equipped self-supportive features,...
Polarization-analyzed small-angle neutron scattering (PASANS) is an advanced technique that enables the selective investigation of magnetic phenomena in materials and distinguishes coherent obscured by incoherent backgrounds, making it particularly valuable for cutting-edge research. The successful implementation PASANS China was achieved first time at newly commissioned Very Small Angle Neutron Scattering (VSANS) instrument Spallation Source (CSNS). This employs a combination double-V...
In this article, continuous PA6/single‐wall nanotubes (SWNTs) nanofiber yarns were obtained by a special electrospinning method; the mechanical and electrical properties electric resistance‐tensile strain sensitivity of as‐spun specially studied. The main parameters in spinning process systematically Scanning electron microscope images tests indicated that optimum for operation voltage = 20 kV, flow rate 0.09 ml/h, winding speed 150 rpm. Transmission microscopy showed SWNTs have aligned...
Nanofiber filaments were produced by a home-made, multi-needle, liquid bath, electrospinning device, and the nanofiber alignment degrees of investigated. The electrostatic fields processes simulated finite-element method, an index, average offset field distribution in needle tips, was established to quantify existing interference. effects number arrangement needles on nanofibers breaking stress analyzed. results showed that there linear negative correlation between with R 2 0.96. larger...
Plant microbiota play essential roles in plant health and crop productivity. Comparisons of community composition have suggested seed, soil, the atmosphere as reservoirs phyllosphere microbiota. After finding that leaves tomato (Solanum lycopersicum) plants exposed to rain carried a higher microbial population size than not rain, we experimentally tested hypothesis is thus-far-neglected reservoir Therefore, were compared with either treated concentrated microbiota, filter-sterilized or...
We use inelastic neutron scattering to study energy and wave vector dependence of spin fluctuations in ${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$, derived from ${\mathrm{SrFe}}_{2\ensuremath{-}x}{\mathrm{Co}}_{x}{\mathrm{As}}_{2}$ iron pnictide superconductors. Our data reveal the coexistence antiferromagnetic (AF) ferromagnetic (FM) at vectors ${\mathbf{Q}}_{\mathrm{AF}}=(1,0)$ ${\mathbf{Q}}_{\mathrm{FM}}=(0,0)/(2,0)$, respectively. By comparing results with those dynamic mean field theory...
Poor survival on plants can limit the efficacy of Biological Control Agents (BCAs) in field. Yet bacteria survive atmosphere, despite their exposure to high solar radiation and extreme temperatures. If conditions atmosphere are similar to, or more than, environmental plant surface, then precipitation may serve as a reservoir robust BCAs. To test this hypothesis, two hundred fifty-four rain-borne isolates were screened for vitro inhibition Erwinia amylovora, causal agent fire blight, well...
Routine strain-level identification of plant pathogens directly from symptomatic tissue could significantly improve disease control and prevention. Here we tested the Oxford Nanopore Technologies (ONT) MinION sequencer for metagenomic sequencing tomato plants either artificially inoculated with a known strain bacterial speck pathogen Pseudomonas syringae pv. or collected in field showing spot symptoms caused by one four Xanthomonas species. After species-level via ONT's WIMP software...
We use inelastic neutron scattering to study spin excitation anisotropy in mechanically detwinned $\mathrm{Ba}{({\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x})}_{2}{\mathrm{As}}_{2}$ with $x=0.048$ and 0.054. Both samples exhibit a tetragonal-to-orthorhombic structural transition at ${T}_{s}$, collinear static antiferromagnetic order wave vector ${\mathbf{Q}}_{1}={\mathbf{Q}}_{\mathrm{AF}}=(1,0)$ below the $\mathrm{N}\stackrel{\ifmmode \acute{}\else \'{}\fi{}}{\mathrm{e}}\mathrm{el}$...
Abstract A small in-plane external uniaxial pressure has been widely used as an effective method to acquire single domain iron pnictide BaFe 2 As , which exhibits twin-domains without strain below the tetragonal-to-orthorhombic structural (nematic) transition temperature T s . Although it is generally assumed that such a will not affect intrinsic electronic/magnetic properties of system, known enhance antiferromagnetic (AF) ordering N ( < ) and create resistivity anisotropy above Here we...
Abstract Earth’s radiation budget and frequency intensity of precipitation are influenced by aerosols with ice nucleation activity (INA), i.e., particles that catalyze the formation ice. Some bacteria, fungi, pollen among most efficient nucleators but molecular basis INA is poorly understood in them. Lysinibacillus parviboronicapiens (Lp) was previously identified as first Gram-positive bacterium INA. Lp associated a secreted, nanometer-sized, non-proteinaceous macromolecule or particle....
We use transport and neutron scattering to study the electronic phase diagram spin excitations of ${\mathrm{NaFe}}_{1\ensuremath{-}x}{\mathrm{Cu}}_{x}\mathrm{As}$ single crystals. Similar Co- Ni-doped NaFeAs, a bulk superconducting appears near $x\ensuremath{\approx}2%$ with suppression stripe-type magnetic order in NaFeAs. Upon further increasing Cu concentration system becomes insulating, culminating an antiferromagnetically ordered insulating $x\ensuremath{\approx}50%$. Using...
Electrospinning is one of the few simple and effective ways to produce nanofibers, which can be used in various fields. However, common assembled nanofiber mats are limited some areas, so static bath was as negative collector yarns. In order improve yields, a novel multi-needle electrospinning using employed, spinning state orientation as-spun yarns different numbers needles described details. The results showed that critical voltages, keeping process stable, increased from 21KV 28KV with...
