The measurement of the energy spectrum cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years data recorded by Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening observed at an about 1.3 TeV, similar previous observations. In addition, a spectral softening 34 revealed for first time with large statistics and well controlled systematic uncertainties, overall significance 4.3σ. DAMPE measurements both protons suggest particle charge dependent energy, although...
Recent observations of the light component cosmic-ray spectrum have revealed unexpected features that motivate further and more precise measurements up to highest energies. The Dark Matter Particle Explorer is a satellite-based experiment has been operational since December 2015, continuously collecting data on high-energy cosmic particles with very good statistics, energy resolution, particle identification capabilities. In this work, latest proton+helium in range from 46 GeV 464 TeV are...
ABSTRACT We report on the Insight-HXMT observations of new black hole X-ray binary MAXI J1820+070 during its 2018 outburst. Detailed spectral analysis via continuum fitting method shows an evolution inferred spin high soft sate. Moreover, hardness ratio, non-thermal luminosity and reflection fraction also undergo evolution, exactly coincident to period when transition takes place. The unphysical is attributed inner disc, which caused by collapse a hot corona due condensation mechanism or may...
We study the evolution of temporal properties MAXI 1820+070 during 2018 outburst in its hard state from MJD 58190 to 58289 with Insight-HXMT a broad energy band 1-150 keV. find different behaviors hardness ratio, fractional rms and time lag before after 58257, suggesting transition occurred at around this point. The observed lags between soft photons 1-5 keV higher bands, up 150 keV, are frequency-dependent: low-frequency range, 2-10 mHz, both timescale dozens seconds but without clear trend...
An extracellular beta-glucosidase (EC 3.2.1.21) was purified from culture filtrate of the anaerobic rumen fungus Orpinomyces sp. strain PC-2 grown on 0.3% (wt vol-1) Avicel by using Q Sepharose anion-exchange chromatography, ammonium sulfate precipitation, chromatofocusing ion-exchange and Superose 12 gel filtration. The enzyme is monomeric with a M(r) 85,400, as estimated sodium dodecyl (SDS)-polyacrylamide electrophoresis, has pI 3.95, contains about 8.5% carbohydrate. N terminus appears...
Abstract Glyphodes pyloalis Walker (Lepidoptera: Pyralididae) is a common pest in sericulture and has developed resistance to different insecticides. However, the mechanisms involved insecticide of G. are poorly understood. Here, we present first whole-transcriptome analysis differential expression genes insecticide-resistant susceptible . Clustering enrichment DEGs revealed several biological pathways enriched Gene Ontology terms were related detoxification or resistance. Genes metabolic...
ABSTRACT We studied the 2018 outburst of black hole transient H 1743 − 322 with a series Insight-HXMT, NICER, and NuSTAR observations, covering 1–120 keV band. With our broad-band X-ray spectral modelling, we confirm that source remained in low/hard state throughout month-long outburst, although it became marginally softer at peak flux. detected Type-C quasi-periodic oscillations (QPOs) followed evolution their properties. The QPO frequency increased from ∼0.1 to ∼0.4 Hz during rising phase...
ABSTRACT Based on Insight-HXMT data, we report the pulse fraction evolution during 2017–2018 outburst of newly discovered first Galactic ultraluminous X-ray (ULX) source Swift J0243.6+6124. The fractions 19 observation pairs selected in rising and fading phases with similar luminosity are investigated. results show a general trend increasing energy at supercritical luminosity. However, relative strength pulsation between each pair evolves strongly phase is larger below 7.71 × 1038 erg s−1,...
The density and distribution of Ixodes pacificus was assessed at 2 parks in north coastal California. I. adults nymphs varied significantly between years, trails, sides trails. Adult ticks occurred on vegetation along sun-exposed trails January through March, their (0-1.93 per 20 m) correlated with brush density, trail width, presence an uphill slope. Nymphs (0.06-5.10 leaf litter shaded May-July. were rare picnic sites (0.00-0.24 m), but nymphal densities (0.93-2.37 comparable those some...
Tachaea chinensis , a parasitic isopod, negatively affects the production of several commercially important shrimp species in China. The mechanism parasite-host interaction cannot be accurately described by transcriptomic and proteomic approaches individually. Here, comparative metabolite profiling was used to achieve broad coverage primary changes Chinese grass Palaemonetes sinensis following T. parasitization. In total, 66 metabolites were significantly differentially accumulated between...
In this study, we describe in detail the life cycle of Tachaea chinensis (Isopoda: Corallanidae), a branchial ectoparasitic isopod that infests freshwater shrimp Palaemonetes sinensis China. We obtained 14 ovigerous T. females (8.22-11.92 mm length) and observed development embryos through 5 sequential ontogenetic stages within brood pouches (marsupium) these females. The number eggs or mancae (post-larval juveniles) held female marsupium ranged from 31 to 86, with mean ± SD 61.25 16.16...
After 34 years, the black-hole candidate EXO 1846-031 went into outburst again in 2019. We investigate its spectral properties hard intermediate and soft states with NuSTAR Insight-HXMT. A reflection component has been detected two but possibly originating from different illumination spectra: state, illuminating source is attributed to a coronal component, which commonly observed other X-ray binaries, whereas state probably produced by disk self-irradiation. Both cases support as low...
Caged compounds are optical probes in which biological signaling molecules rendered inert by attachment of a photosensitive protecting group (PPG).Following Wittgenstein's dictum "Meaning is use", the key features such deduced consideration properties most widely used caged that have been successfully applied to test numerous hypotheses.
Schistosomes cause schistosomiasis, one of the neglected tropical diseases as defined by WHO. For decades, treatment schistosomiasis relies on a single drug, praziquantel. Due to its wide use, there is justified fear resistance against this and vaccine not available. Besides biological relevance in signal transduction processes, class G protein-coupled receptors (GPCRs) also well suited for drug design. Against background, we characterized GPCR Schistosoma mansoni, SmGPCR20, at molecular...
