Let M be a type II 1 von Neumann algebra, S (M) be the Murray–von Neumann algebra associated with M and let A be a ⁎-subalgebra in S (M) with M ⊆ A. We prove that any ring derivation D from A into S (M) is necessarily inner. Further, we prove that if A is an E W ⁎ -algebra such that its bounded part A b is a W ⁎ -algebra without finite type I direct summands, then any ring derivation D from A into L S (A b) — the algebra of all locally measurable operators affiliated with A b , is an inner derivation. We also give an example showing that the condition M ⊆ A is essential. At the end of this paper, we provide several criteria for an abelian extended W ⁎ -algebra such that all ring derivations on it are linear. [ABSTRACT FROM AUTHOR]

Lung ischemia-reperfusion injury (LIRI) poses a significant challenge in various clinical scenarios. Despite extensive research on the pathogenesis and potential treatments of LIRI, there is a notable absence of bibliometric analysis. We summarized the results of LIRI research through two searches on the Web of Science, covering data from 1979 to 2023 with topic words "lung" and "reperfusion injury". The collected data were analyzed and visualized based on country, author(s), and keywords by bibliometric software. The keyword "programmed cell death" was further added to explore the hotspot of the LIRI research field. The initial analysis of 1648 research articles showed a total of 40 countries and 7031 researchers were involved in the publications, with America being the most productive country in the research field of LIRI. Keyword analysis revealed that the evolving focus of LIRI research has progressively transitioned from, lung transplantation, primary graft dysfunction, inflammation, oxidative stress, and ex vivo lung perfusion to cell death. Subsequently, 212 publications specifically addressing programmed cell death (PCD) in LIRI were identified, which clarified the recent hotspot of the LIRI field. With closer international cooperation and increasing research scale, the LIRI research focused mainly on the pathogenesis and potential therapeutic interventions for LIRI. PCD in LIRI is becoming a trending topic and will continue to be a hotspot in this field. Our study may offer valuable guidance for future research endeavors concerning LIRI. [ABSTRACT FROM AUTHOR]

In this study, a neutron and γ-ray absorbing (Gd 2 O 3 +W)/Al composite was fabricated by vacuum sintering. Firstly, through Monte Carlo Neutron and Photo Transport Code (MCNP) calculations, the content of Gd 2 O 3 and W in the composite was determined to be 10 wt% and 25 wt%, respectively. Then, the influence of sintering temperature and sintering time on the microstructure, density, compression properties and electrochemical corrosion behavior of the (Gd 2 O 3 +W)/Al composites were investigated. The results indicate that sintering temperatures below 600 °C and sintering times shorter than 2 h led to insufficient density of the composite. Conversely, sintering temperatures above 600 °C and sintering times longer than 2 h caused W to agglomerate, resulting in a decrease in the density of the composite and a deterioration of its electrochemical performance. Therefore, the optimal sintering temperature and sintering time for the (Gd 2 O 3 +W)/Al composites were determined to be 600 °C and 2 h, respectively. Finally, the immersion corrosion performance in H 3 BO 3 solution of the composite fabricated by the optimal process parameters was studied in detail. It was found that pitting was the main corrosion form of the (Gd 2 O 3 +W)/Al composite, and an oxidation film mainly composed of Al 2 O 3 was formed on the surface. [ABSTRACT FROM AUTHOR]

• Bactrocera and Zeugodacus pests trapped in pomelo groves of China. • B. dorsalis was the most abundant, followed by Z. cucurbitae. • Other trapped species: B. latifrons , B. rubigina , Z. scutellate , Z. tau. • B. minax and B. tsuneonis , two destructive citrus pests, were not found. • Methyl eugenol + Steiner trapped the highest number, followed by cuelure + Steiner. Certain tephritid fruit flies, such as the oriental fruit fly, Bactrocera dorsalis , the Chinese citrus fly, B. minax and the Japanese orange fly, B. tsuneonis (Diptera: Tephritidae: Dacinae), are destructive citrus pests in China. A two-year trapping study was conducted in pomelo, Citrus maxima , groves in Fujian Province of China. The objectives of this study were to investigate the species, the abundance of tephritid fruit flies in the orchards, as well as the efficacy of the selected lure traps to these flies. Four lure traps or devices, i.e. methyl eugenol + Steiner trap (ST), cuelure + ST, ammonium acetate + putrescine + ST, and sticky spheres, were deployed from June to November 2017 and April to October 2018. Six economically significant Dacini pests were trapped during the period. These flies are B. dorsalis , the melon fruit fly, Zeugodacus cucurbitae , the pumpkin fruit fly, Z. tau , the Malaysian fruit fly, B. latifrons , and other two species - B. rubigina and Z. scutellatus. B. dorsalis was the most abundant, accounting for more than 50% of the capture, followed by Z. cucurbitae. The remaining four species accounted for less than 2% of the total capture. B. minax and B. tsuneonis , two destructive citrus-damaging tephritid fruit flies in China, were not found during the trapping period. Methyl eugenol trapped the highest number of fruit flies, followed by cuelure. [ABSTRACT FROM AUTHOR]

Phosphorus leaching is severe in the orchard of Fujian province, especially in Pinghe where 'Guanximiyou' Pomelo is extensively grown. It triggers decreased phosphorus fertilizer utilization efficiency and causes eutrophication of waterways. Microorganisms can promote plant growth, mineralize organic phosphorus and solubilize inorganic phosphorus in soil. Here, metagenomics was used to explore the effects of selenium combined with chitin inputs on genes and microorganisms related to the soil phosphorous cycle. Phenotypic approaches were used to explore phosphorus accumulation in plants and the leaching of soil phosphorus from leaching column experiments. The results showed that compared with the control, the combination of selenium and chitin could significantly promote phosphorus accumulation in leaves by 33.3% and reduce the leaching of phosphorus from soil by 29.11%. Addition of selenium and chitin also changed the composition of microbial community, thus affecting the relative abundance of genes and microorganisms involved with phosphorus cycle. For example, the PstSAC protein which mediates phosphorus transport in soil phosphorus cycle increased in the current study. And it may promote microbes to immobilize more phosphorus in their biomass. These findings provide a strategy to reduce the loss of phosphorus from soil and lower the risks of eutrophication of waterways, which would contribute to a sustainable and environmental friendly agriculture. [Display omitted] • The combination of Se and chitin reduced phosphorus leaching from soil. • Se and chitin promoted the phosphorus accumulation in pomelo leaves. • Se and chitin affected the microbial communities. • Se and chitin may affect the phosphorus immobilization through PstSAC.

The present work is aimed to investigate the influences of arc current on the microstructure evolution of the as-deposited Cr coatings for accident tolerant fuel. Cr coatings were prepared on the surface of Zr-4 alloy by multi-arc ion plating with different arc currents. Electron backscattering diffraction (EBSD) technology was employed to characterize the microstructure evolution of the as-deposited Cr coatings, including the distribution of grain boundaries, the mean grain size, the crystallographic orientation distribution, the dislocation density and dynamic recrystallization (DRX). The results showed that: regarding the mean grain size of the Cr coating, the largest was that prepared by 80A, followed by 100A, 70A and 90A; regarding the number fraction of HAGBs, the highest was that prepared by 80A, followed by 90A, 100A and 70A; regarding the grain morphology, the Cr coating prepared by 70A exhibited equiaxed grains without obvious texture, while that prepared by 80A, 90A and 100A had elongated columnar grains along the building direction; regarding the crystal phase, the Cr coating prepared by 80A, 90A and 100A exhibited the (100)〈001〉 texture component; regarding the dislocation density, there was a large number of scattered high dislocation density regions in the Cr coating prepared by 70A, the high dislocation density regions only appeared on the surface layer in the Cr coating prepared by 90A, and along the boundaries of elongated grains in the Cr coating prepared by 100A, while it was almost non-existent in the Cr coating prepared by 80A; regarding the DRX, discontinues DRX (DDRX) was the principal DRX mechanism for the Cr coating prepared by 70A, while continues DRX (CDRX) was the dominant DRX mechanism for the Cr coatings prepared by 80A, 90A and 100A. • The microstructure of Cr coatings prepared by different arc current is characterized by EBSD. • The effect of arc current on the microstructure evolution is studied. • The DRX mechanism of Cr coatings prepared by different arc current is investigated.

Aluminum (Al) coatings were deposited on Zr-4 alloy substrate by magnetron sputtering. The microstructure parameters of the as-deposited coating were characterized by means of scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and electron backscattered scattering detection (EBSD). The results showed that: via the SEM and EDS, it can be found that Al atoms and Zr atoms undergo rapid interdiffusion at the interface, forming an Al-Zr diffusion layer with a thickness of about 1.5 μm; via X-ray diffraction line broadening, the estimated crystal size was 81.53 nm and the as-deposited Al coating presences lattice tensile strain; via EBSD, the fraction of HAGBs is overwhelmingly larger than that of LAGBs and the mean grain size is 0.55 μm, also, the Al coating exhibits the (100)<001> texture. • The crystal size and lattice strain of Al coating are studied by XRD. • The grain size, grain boundary, and crystallographic orientation of Al coating are studied by EBSD.

The carboxylate group-based organic electrode materials are promising anodes for rechargeable sodium ion batteries (SIBs) due to the low cost, abundance, environmental benignity and high sustainability of organic materials. Here, we compare the electrochemical performance of three carboxylate group-based organic electrode materials in SIBs, and identify that the two carboxylate groups in the para position of the benzene ring are electrochemical active centers to reversibly react with Na-ions and electrons. The carboxylate group-based anode, trisodium 1,2,4-benzenetricarboxylate (TBC), exhibits exceptional electrochemical performance in SIBs, in terms of high specific capacity (195 mAh g−1) and long cycle life (600 cycles). The third carboxylate group in TBC enhances the sodiation/de-sodiation potentials, and reduces its solubility in the electrolyte, resulting in a highly stable organic anode. The low cost, high sustainability, high capacity and high cyclic stability of TBC render it a promising anode material for SIBs. • Trisodium 1,2,4-benzenetricarboxylate is developed as a new organic anode material. • The new organic anode exhibits exceptional performance in Na-ion batteries. • Three carboxylate groups stabilize the organic anode. • The stable chemical structure and interface contribute to the high performance.
