Vanadium mineralization at Los Chihuidos deposit of the Neuquén Basin is linked to the development of a redox front system related to the inflow of hydrocarbons into the red sandstone of the Huincul Formation.Interaction of hydrocarbons with oxidized red beds and connate water generated redox reactions where hematite was dissolved due to iron reduction resulting in the discoloration of the red strata.At the contact between oxidized red sandstone and reduced white sandstone,precipitation of specific mineral phases resulted in the V ore with minor amounts of Cu.With the implementation of the redox interface,abundant V-montmorillonite and V-hematite precipitated at the more oxidizing conditions and Cu-V-corrensite-type at the more reducing conditions of the redox front.As the redox front advanced with fluids constantly migrating into the reservoir,more reducing conditions were stablished,promoting chloritization and minor illitization with V-Cu incorporation and continuous upgrading of the ore.main ore mineralogy consists of clay minerals including V-bearing montmorillonite,Cu-V-corrensite-type,V-di-trioctahedral chlorite and Cu-tri-trioctahedral chlorite with minor V-illite-smectite mixed-layer minerals and associated secondary V-hematite.Chloritization over illitization was favored due to high amounts of Fe and mg in detrital clasts and in connate fluids and by low K availability related to low amounts of detrital K-feldspar.The spatial transition of V and/or Cu bearing clay minerals observed through the mineralized redox front at Los Chihuidos deposit(kaolinite→smectite→illite/smectite→corrensite-type→di-trioctahedral-chlorite→tri-trioctahedral-chlorite)and the related variation of V-Cu concentrations in bulk rock are indicative of increasing pH and decreasing Eh of resident solutions from red to white sandstones during the hypogene mineralization process.Late influx of Cu-rich oxidized basinal brines precipitated main copper ore with Cu-sulfides in the white sandstone up to the contact with the redox front in co

Interleukin-27 is a pleiotropic cytokine whose functions during bacterial infections remain controversial,and its role in patients with S.aureus osteomyelitis is unknown.To address this knowledge gap,we completed a clinical study and observed elevated serum IL-27 levels(20-fold higher,Pmpared with healthy controls.Remarkably,IL-27 serum levels were 60-fold higher in patients immediately following septic death than in uninfected patients(Pmyelitis in WT and IL-27Rα^(−/−)mice with and without exogenous IL27 induction by intramuscular injection of rAAV-IL-27p28 or rAAV-GFP,respectively.We found that IL-27 was induced at the surgical site within 1 day of S.aureus infection of bone and was expressed by m0,m1 and m2 macrophages and osteoblasts but not by osteoclasts.Unexpectedly,exogenous IL-27p28(~2 ng·mL^(−1) in serum)delivery ameliorated soft tissue abscesses and periimplant bone loss during infection,accompanied by enhanced local IL-27 expression,significant accumulation of RORγt^(+)neutrophils at the infection site,a decrease in RANK^(+) cells,and compromised osteoclast formation.These effects were not observed in IL-27Rα^(−/−)mice compared with WT mice,suggesting that IL-27 is dispensable for immunity but mediates redundant immune and bone cell functions during infection.In vitro studies and bulk RNA-seq of infected tibiae showed that IL-27 increased nos1,nos2,il17α,il17f,and rorc expression but did not directly stimulate chemotaxis.Collectively,these results identify a novel phenomenon of IL-27 expression by osteoblasts immediately following S.aureus infection of bone and suggest a protective role of systemic IL-27 in osteomyelitis.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in various analyses performed at the Large Hadron Collider,as Standard model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced background.This paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration,using √s=13 TeV proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAS experiment.Two taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines several jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet pseudorapidity.Differences in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points.

通过一个试验,研究集约化饲养条件下不同屠宰日龄(47～65d)的两个商品肉鸡品系(罗斯508和Cobb500)胸深肌病(deeppectoralmyopathy,DPm)的发病率。试验在意大利一家一流的家禽加工厂进行,在为期6个月的试验期内随机从151个屠宰肉鸡群中选取120700羽肉用公鸡,根据胸小肌有无眼观肌病以及肌肉损伤的病变程度(分发病早期(表现为出血)和发病后期(灰色或绿色)对肉鸡的DPm进行评估。检测表明,各肉鸡群屠体的DmP总体发病率平均为0.84%(其中处于发病早期和发病晚期的屠体比例分别为0.62%和0.22%),各试验肉鸡群之间的DPm发病率波动幅度很大(0%～16.7%),另外处于发病早期和发病晚期的肉鸡所占比例变化也很大,分别为0%～12.0%和0%～5.6%;对两个肉鸡品种的DmP发病率比较后发现,罗斯508肉鸡的发病率高于Cobb500肉鸡(P≤0.01),该结果是由于罗斯508肉鸡的DmP发病早期(0.94%(罗斯508)对0.26%(Cobb500),P≤0.01)和发病后期(0.33%对0.09%,P≤0.01)比例均高于Cobb500肉鸡。
