Despite widespread adoption and outstanding performance, machine learning models are considered as ‘‘blackboxes’’, since it is very difficult to understand how such models operate in practice. Therefore, in the powersystems field, which requires a high level of accountability, it is hard for experts to trust and justify decisionsand recommendations made by these models. meanwhile, in the last couple of years, Explainable ArtificialIntelligence (XAI) techniques have been developed to improve the explainability of machine learning models,such that their output can be better understood. In this light, it is the purpose of this paper to highlight thepotential of using XAI for power system applications. We first present the common challenges of using XAI insuch applications and then review and analyze the recent works on this topic, and the on-going trends in theresearch community. We hope that this paper will trigger fruitful discussions and encourage further researchon this important emerging topic.

Neural Regeneration Research 2022年第5期17卷 997-998页

作者： Erin l.Walden Shuxin li Shriners Hospitals Pediatric Research Center Department of Neural SciencesLewis Katz School of Medicine at Temple UniversityPhiladelphiaPAUSA

After central nervous system(CNS)injury,severed axons fail to regenerate and their disconnections to the original targets result in permanent functional deficits in patients(mahar and Cavalli,2018).Both the diminished intrinsic regenerative capacity of mature neurons and the inhibitory CNS milieu contribute to the regenerative failure following CNS injury.

7075铝合金兼具高比强度、低密度和良好耐腐蚀性等优点,在航空航天领域应用广泛。基于传统制备方法存在加工过程复杂、材料利用率低及零件表面精度低等问题,使用激光熔丝增材制造技术可在较短时间和较少成本下成型低缺陷高精度的7075铝合金零部件。本研究采用不同工艺参数制备了7075铝合金单层单道和单道多层增材试样,基于有限元方法系统分析了不同激光功率对沉积层温度场分布和微观组织的影响,以揭示热输入诱导的微观组织差异对7075铝合金沉积层硬度的影响机理。结果表明:随着激光功率从1 600 W增加到2 200 W,熔池峰值温度提高12.5%,温度梯度从62.8℃/mm减小至12.4℃/mm,沉积结构高温区域面积增大,熔宽增长20.85%,单道多层试样的峰值温度增幅大于单层单道。随着激光功率增加,沉积层上部、中部和下部的晶粒尺寸增大,晶界处第二相析出物含量减少,从底部至顶部均出现柱状晶至等轴晶转变。不同激光功率下增材试样在不同位置的显微硬度均达到90 HV以上。

通过简单易得的氯代2-肼基吡啶和芳香醛衍生物缩合与氟硼配位,一锅两步反应合成了系列新型的氟硼配位吡啶肼基醛腙染料,将其命名为BOPAHs.这些染料分子通过核磁共振、高分辨质谱和晶体结构进行了表征.其主吸收在400～600 nm范围内,发射波长在500～700 nm范围内.随着溶剂极性的增加,它们的吸收/发射峰逐渐红移,同时斯托克斯位移增大,表明这些分子具有明显的分子内电荷转移特性.同时,通过密度泛函理论计算进一步证实了这一特性.此外,这些BOPAHs在溶液中的荧光较弱,但它们都表现出明显的聚集诱导发射特性,可能是由于分子在聚集态下构象固定导致弱的分子间相互作用所致.

华文大河小说《侨歌》三部曲是印尼华文作家黄东平的经典之作,被誉为“华侨史诗”。《侨歌》三部曲呈现了吴阿贵从闽南“新客”、商店伙计到矿山矿工的身份及行为、心态的动态变化,刻画吴阿贵的精神成长史成为《侨歌》三部曲的重要亮点。吴阿贵个人的生命史浓缩了整个近现代中国底层民众跨国移民、挣扎求生、艰苦奋斗的离散体验,其精神成长史体现出闽南文化的精神印记;吴阿贵突破个人狭隘身份意识向一种集体“大我”身份意识的转化,也反映了在文化混杂的东南亚土地上,一种跨越种族隔阂的阶级力量的萌芽与茁壮成长。

This paper is devoted to the existence and the uniqueness of the entropy solution for a general scalar conservation law associated with a forced bilateral obstacle condition in a bounded domain of Rp, p>= 1. The method of penalization is used with a view to obtaining an existence result. However, the former only gives uniform l -estimates and so leads in fact to look for an Entropy measure-Valued Solution, according to the specific properties of bounded sequences in l . The uniqueness of this EmVS is proved. Classically, it first ensures the existence of a bounded and measurable function U entropy solution and then the strong convergence in lq of approximate solutions to U.

Isolated case reports have circumstantially linked the use of the herbicide 2.4-dichlorophen-oxyacetic acid (2,4-D) to polyneuropathy. However, a critical review of the literature reveals numerous reasons for doubting a relationship of 2.4-D to polyneuropathy: (1) too few cases given the wide use of the chemical: (2) no valid toxicologic or epidemiologic evidence; (3) the diversity of antecedent illness; (4) an unlikely time sequence of antecedent illness to exposure (pharmacokinetics); (5) the lack of polyneuropathy in medical patients given repetitive doses of 2.4-D; (6) the lack of polyneuropathy in heavily exposed military personnel involved in operation Ranch Hand; (7) the biological properties of 2.4-D which minimize penetration of 2.4-D into the nervous system under normal exposure conditions; and (8) the lack of polyneuropathy in a variety of experimental animal species given 2,4-D by several routes of exposure and at dose levels and durations of exposure many times greater than human applicator exposure. Thus, the weight of evidence indicates that 2.4-D is an unlikely cause of polyneuropathy. 1990 Academic Press. Inc.

Bismuth-based Sillen-Aurivillius compounds are being explored as efficient photocatalyst materials for the degradation of organic pollutants due to their unique layered structure that favours effective separation of electron-hole pairs. In this work, we synthesized Sillen-Aurivillius-related Bi2YO4Cl with the bandgap of 2.5 eV by a simple solid-state reaction and sensitized with rhodium nickel (RhNi) nanoparticles (NPs) to form the RhNi/Bi2YO4Cl heterostructure. Photocatalytic activities of BiOCl, Bi2YO4Cl and the RhNi/Bi2YO4Cl heterostructure were examined for the degradation of rhodamine- 6G under visible-light illumination. Results demonstrated that the photocatalytic dye degradation efficiency of RhNi/Bi2YO4Cl heterostructures is higher than those of BiOCl and Bi2YO4Cl, attributed to the synergistic molecular-scale alloying effect of bimetallic RhNi NPs. The plausible mechanism for the degradation of rhodamine-6G and the effective electron-hole pair utilization mechanism were discussed.

The effects of substituent type and position on the proton transfer reaction of 3-hydroxytropolone(3-OHTRN) have been investigated theoretically by using density functional theory at the level of B3lYP/ 6-31+G** method. The influence of solvent on the proton transfer reactions of substituted 3-OHTRN has been examined using the self-consistent isodensity polarized continuum model(SCI-PCm) in water. As a result, while the proton transfer reaction is kinetically the easiest by substitution on position 3 of-NH2 group in the gas phase, it is kinetically the easiest by substitution on position 5 of the same group in water. In addition, these reactions are either kinetically or thermodynamically easier in the gas phase than that in water, except the reaction of structure with-NH2 group at position 6.
