SARS-CoV-2 has been demonstrated to be highly susceptible to neuron-and glial-like cells,1 but there is no consensus regarding how the virus affects neurons following neuroinvasion.It is therefore unknown if and how SARS-CoV-2 maintains the homeostasis of neuronal cells.Herein,we revealed that the receptor-binding domain(RBD)of the SARS-CoV-2 spike protein acted as an extracellular remodeling component to undermine epigenetic regulation,perturbnascentRNA(nsRNA)transcription,promote mitochondrial biogenesis,and increase cellular viability in SH-SY5Y cells.

We collected high-quality teleseismic events recorded by 12 broadband seismographs deployed in the Anyuan Coal Mine and its adjacent areas in Pingxiang City,Jiangxi Province for nearly two years.The H-κ-c stacking method was employed to obtain the crustal thickness and Poisson's ratio distribution,then the characteristics of crustal structure below the stations were obtained by using the time-domain linear inversion method.The crustal thickness in the Anyuan Coal Mine and its adjacent areas ranges from approximately 32~35 km,with an average thickness of 33 km,which is consistent with the crustal thickness results in South China from previous studies using the receiver function method.The average Poisson's ratio of the crustal bulk composition in the study area varies between 0.22 and 0.25,which is lower than the global value with a 0.27 average,indicating a predominantly intermediate-acidic or felsic crustal composition.There is a weak negative correlation between Poisson's ratio and crustal thickness estimates in the Anyuan Coal Mine and its adjacent areas,suggesting that the absence of mafic-ultramafic materials in the lower crust is associated with the process of crustal delamination.The velocity inversion results indicate that the crustal structure including three velocity discontinuity interfaces,with the first at a depth of approximately 1.5 km,the second at about 10~15 km,and the third being the Moho.The study also indicates that the results obtained by the H-κ-c stacking method are significantly better than those obtained by the H-κmethod,effectively reducing the standard deviation and dispersion of crustal thickness and vP/vSratio.

The Mn-Ce-Fe mixed oxide(MCFe)was prepared by co-precipitation and the catalytic performance was tested by using 1,2-dichlorobenzene(1,2-DCB)and furan as model molecules of PCDD/F.The effect of O_(2)concentration,SO_(2) and NO on the catalytic activity was studied.At 270℃,the MCFe oxide catalyst presents significant simultaneous removal efficiency of 75.25%and 100%for 1,2-DCB and furan,respectively.Brunauer-Emmett-Teller(BET)method(BET),X-ray diffraction(XRD),scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),Fourier transform infrared spectroscopy(FTIR),H_2-temperature programmed reduction(H_(2)-TPR),NH_(3)-temperature programmed desorption(NH_3-TPD)and O_(2)-TPD were used to characterize the catalysts before and after the reaction.Competition tests suggest that the oxidation behavior of furan occurred prior to that of 1,2-DCB.According to the intermediate products detected by gas chromatography-mass spectrometry(GC-MS),the by-products include chlorinated hydrocarbons,long-chain hydrocarbons,ketone,etc.Possible catalytic oxidation reaction paths are proposed.

Ternary strategy with a suitable third component is a successful strategy to improve the photovoltaic performance of organic solar cells(OSCs). Very recently, Y-series based giant molecule acceptors or oligomerized acceptors have emerged as promising materials for achieving highly efficient and stable binary OSCs, while application as third component for ternary OSCs is limited. Here a novel π-extended giant dimeric acceptor, GDF, is developed based on central Y series core fusion and rigid BDT as linker, and then incorporated into the state-of-the-art PM1:PC6 system to construct ternary OSCs.The GDF has a near planar backbone, resulting in increased π-conjugation, excellent crystallinity, and good electron transport capacity. When GDF is introduced into the PM1:PC6 system, it ensues in a cascade like the lowest unoccupied molecular orbitals(LUMO) energy level alignment, a complementary absorption band with PM1 and PC6, higher and balanced hole and electron mobility, slightly smaller domain size, and a higher exciton dissociation probability for PM1:PC6:GDF(1:1.1:0.1) blend film. As a consequence, the PM1:PC6:GDF(1:1.1:0.1) ternary OSC achieves a champion PCE of 19.22%, with a significantly higher open-circuit voltage and short-circuit current density, compared to 18.45% for the PM1:PC6(1:1.2) binary OSC. Our findings show that employing a π-extended giant dimeric acceptor as a third component significantly improves the photovoltaic performance of ternary OSCs.

This study evaluated the effects of flavonoids from mulberry leaves (FML) on plasma biochemical indices,serum activities of lipid metabolism-related enzymes,fat morphology,fatty acid composition,and lipid metabolism in different adipose tissues of finishing pigs.We used 120 Chinese hybrid barrows of Berkshire and Bama mini-pigs with an average initial body weight of 45.11±4.23 kg.The pigs were randomly assigned to five treatment groups and fed a control diet based on corn,soybean meal,and wheat bran or a control diet supplemented with 0.02%,0.04%,0.08%,or 0.16%FML.Each experimental group had six replicates (pens),with four pigs per pen.After a 7-d adaptation period,the feeding trial was conducted for 58 d.Blood and adipose tissue samples were collected from 30 pigs (one pig per pen)at the end of the test.The results showed that FML supplementation significantly decreased the feed intake to body gain ratio,the plasma concentrations of total cholesterol and free fatty acids,and the serum activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase (linear or quadratic effects,P<0.05),and decreased the plasma triglyceride concentration (quadratic,P=0.07).Increasing FML supplementation increased the average daily gain and serum activities of lipoprotein lipase (linear and quadratic effects,P<0.05) and adipose triglyceride lipase (linear,P<0.05).Dietary FML supplementation decreased the adipocyte area in the dorsal subcutaneous adipose (DSA) tissue of finishing pigs (linear,P=0.05) and increased the adipocyte area in the visceral adipose tissue (quadratic,P<0.01).Increasing FML supplementation decreased the C20:1 content in DSA,abdominal subcutaneous adipose,and visceral adipose tissues of finishing pigs (P<0.05) and increased the C18:3n3 and n-3 PUFA contents(P<0.05).The lipid metabolism genes were regulated by the PPARγ-LXRa-ABCA1 signaling pathway,and their expressions differed in different adipose tissues.These findings suggest that FML improved growth performance,regulated lipid metabolism,inhibited fat production

为落实政府碳减排要求并保证企业经济的可持续发展,碳交易机制成了一种有效的经济手段。碳交易背景下,制造企业为实现低碳目标而增加减排投资成本,往往更容易关注利润分配的公平性。此时,如何基于公平关切偏好进行减排投资和利润分配成为供应链协调决策的重点。以一家生产低碳产品的制造商和一家负责产品销售的零售商为对象,综合考虑碳交易机制、企业碳减排投资和公平关切偏好因素的影响,构建了一个可持续的低碳供应链,并利用博弈理论和收益分配绝对公平方法,探讨了制造商公平关切决策情形下供应链系统最优定价以及减排决策过程,进一步采用碳减排成本分担契约对供应链系统决策过程进行协调,并获得了最优的契约参数值。研究结果表明:制造商采取了提高产品批发价格和降低减排率的策略以减少因减排技术投资而产生的利润分配不公平对待,该策略损失了自身和合作者的利润。为了实现低碳供应链成员之间利益的有效协调,本文设计的成本分担契约在提高供应链系统减排率的同时还可以实现各成员利润的帕累托改进。另外,碳交易机制有利于促使企业进行碳减排投资以提高产品的减排水平。研究结果为进一步改善上下游企业之间的关系和促进供应链系统经济与环境的可持续发展提供参考。

本文在双向生长理论模式的框架内,从跨语言比较的视角研究汉语和英语儿童动词短语结构层(即VP层)的获得与生长。通过考察三名北京儿童和CHILDES语料库一名英语儿童的语言发展跟踪数据,本文发现儿童在独词阶段主要产出VP层内的宾语和动词,在双词阶段则先产出动宾结构,后产出主谓结构,而且动宾结构的数量远远多于主谓结构。该研究发现说明,汉语儿童和英语儿童VP层的获得顺序具有相同的特点,即VP层内的动词和宾语先获得,主语后获得,VP层的获得以自下而上的顺序进行。本文指出,这一获得顺序具有跨语言的普遍性。VP层以自下而上的顺序浮现,符合双向生长模式对VP层获得顺序的预测,也与最简方案框架下VP层的派生过程一致。

Wang等提出了求解带线性约束的多块可分非凸优化问题的带Bregman距离的交替方向乘子法(Bregman ADMM),并证明了其收敛性.该文将进一步研究求解带线性约束的多块可分非凸优化问题的Bregman ADMM的收敛率,以及算法产生的迭代点列有界的充分条件.在效益函数的Kurdyka-Lojasiewicz (KL)性质下,该文建立了值和迭代的收敛速率,证明了与目标函数相关的各种KL指数值可获得Bregman ADMM的三种不同收敛速度.更确切地说,该文证明了如下结果:如果效益函数的KL指数θ=0,那么由Bregman ADMM生成的序列经过有限次迭代后收敛;如果θ∈(0,1/2),那么Bregman ADMM是线性收敛的;如果θ∈(1/2,1),那么Bregman ADMM是次线性收敛的.

地应力对岩体爆炸应力与爆炸能量的分布有重要影响。针对深部岩体爆破冲击波能量分布,基于叠加原理,计算地应力和爆炸荷载双重作用下岩体爆炸应力分布,结合岩体破坏准则,得到了冲击波作用下深部岩体的破坏特征,分析不同工况下传递入深部岩体引起爆破扩腔、径向裂隙扩张及岩石弹性变形的冲击波能量占比,采用数值模拟方法探究了地应力对岩体爆破冲击波能量分布的影响。研究结果表明:岩体性质、炸药性能及地应力水平均会对深部岩体冲击波能量分布产生显著影响;高地应力环境下,硝铵炸药传递入硬岩(花岗岩)的冲击波总能量占比及有效能量的占比较于软岩(页岩)更小,与低性能炸药相比,采用高性能炸药爆破时传递入花岗岩的冲击波总能量占比及有效能量的占比更大;随地应力增大,用于爆腔膨胀的冲击波能量占比基本不变,用于裂隙扩张的冲击波能量占比近似呈线性减小,用于引起弹性变形的冲击波能量占比近似呈指数增长;高地应力环境下,传递入岩体的冲击波总能量占比虽然较大,但有效能量的占比较小;研究成果可为改善深部岩体爆破冲击波能量分布及提升岩体爆破效果提供参考。

Autonomic disturbances often occur in patients with acute cerebrovascular disease due to damage of the central autonomic network. We summarize the structures of the central autonomic network and the clinical tests used to evaluate the functions of the autonomic nervous system.We review the clinical and experimental findings as well as management strategies of post-stroke autonomic disturbances including electrocardiographic changes, cardiac arrhythmias, myocardial damage, thermoregulatory dysfunction, gastrointestinal dysfunction, urinary incontinence, sexual disorders, and hyperglycemia. The occurrence of autonomic disturbances has been associated with poor outcomes in stroke patients. Autonomic nervous system modulation appears to be an emerging therapeutic strategy for stroke management in addition to treatments for sensorimotor dysfunction.
