The production of ultra-low sulfur clean fuels holds global significance for improving energy efficiency and reducing environmental pollution. Photocatalytic aerobic oxidative desulfurization（PODS） offers an attractive approach to efficiently remove refractory heterocyclic aromatic sulfur compounds under mild conditions. However, the sluggish charge dynamics,insufficient molecule activation, and slow mass transfer within photocatalysts restrict the overall desulfurization efficiency,hindering the widespread application of this technology. Herein, we developed a defective g-C3N4（M1U3CN） photocatalyst with bridged N3Cvacancies and hierarchical porous structures to address these limitations. This catalyst not only demonstrates outstanding dibenzothiophene（DBT） removal efficiency of 99.6% for model oil with high conversion and selectivity but also achieves complete sulfur removal from gasoline as well as 96.7% sulfur removal for distilled diesel at room temperature,successfully achieving ultradeep aerobic oxidative desulfurization. The introduction of rich N3Cvacancies and abundant micromeso-macroporous distribution in M1U3CN enhances kinetic efficiencies by promoting charge carrier separation, mass transfer,and molecular activation simultaneously; resulting in exceptional PODS performance. This work provides a collaborative strategy to overcome kinetic challenges in aerobic oxidative desulfurization via defect and structural engineering of the catalyst.

领导情境因素对于员工创新有着重要影响,领导积极反馈和消极反馈在影响员工创新绩效过程中发挥着不同作用。为在同一框架下揭示这种差异性作用,本文在趋近-回避理论框架下构建了两类领导反馈对员工创新绩效影响的综合模型,首先考察了员工趋近-回避工作重塑的平行中介作用,然后结合自我决定理论考察了员工的绩效趋近-回避目标导向在其中发挥的调节作用。通过对230名科技员工的三阶段数据分析,本文发现:领导积极反馈通过提升员工趋近型重塑促进员工创新绩效,领导消极反馈通过员工回避型重塑抑制员工创新绩效;绩效趋近目标导向在领导积极反馈通过趋近重塑影响创新绩效中具有互补效应,而绩效回避目标导向在领导消极反馈通过回避重塑影响创新绩效中具有强化效应。本文针对两类领导反馈影响创新绩效的差异作用给出了整合性的解释,打开了领导反馈影响创新的行为过程性“黑箱”,同时也为管理者如何审慎、合理利用两种领导反馈以促进员工创新提供一定启发。

Diffuse-type tenosynovial giant cell tumor(dTGCT) is a destructive but rare benign proliferative synovial neoplasm. Although surgery is currently the main treatment modality for dTGCT, the recurrence risk is up to 50%. Therefore, there is a great need for effective drugs against dTGCT with minor side effects. The Janus kinase(JAK)/signal transducer and activator of transcription(STAT) signaling plays a central role in rheumatoid arthritis(RA), a disease with similar characteristics as dTGCT, but its function in dTGCT remains *** fibroblast-like synoviocytes(FLS) and macrophages were isolated from 10 synovial tissue samples from dTGCT patients for the screening and validation of the five clinically approved JAK inhibitors to treat RA against dTGCT. Cell viability, cell death, inflammation and the activity of the JAK family members of cultured dTGCT FLS(both 2-D and 3-D) and macrophages were investigated for the efficacy of the JAK inhibitors. Here, we found that similar to RA, JAK/STAT signaling was markedly activated in the dTGCT synovium. Of the 5 JAK inhibitors, peficitinib was shown to have the most potency in addressing some of the pathological responses of dTGCT FLS and *** potency of peficitinib was much higher than pexidartinib, which is the only FDA-approved drug for dTGCT. Mechanistically, peficitinib inhibited tyrosine kinase 2(TYK2), a JAK family member necessary for the pathological progression of dTGCT FLS and macrophages. In summary, we not only revealed JAK/STAT(especially TYK2) signaling as the major mechanism underlying dTGCT, but also identified peficitinib as a promising drug against dTGCT.

由于同一个时刻包含多个音符的多音乐谱其音符符头距离近、符号间依赖关系复杂,使得多音光学乐谱识别极具挑战.传统基于卷积和序列建模的方法,由于经典卷积存在移不变性难以精确表示音符的纵向位置信息,而传统针对上下文序列建模的方法难以有效表征调号中变音记号与五线谱内符头的空间相关性,存在符头音高识别不准、变音记号作用范围有限的问题,从而影响音符音高、时值标注的准确性.针对以上问题,提出了一种强化音符位置及方向先验信息的多音光学乐谱识别方法.首先,提出一种纵向位置编码方法,将纵向位置信息嵌入乐谱图像,以更精确地表示符头的纵向位置信息,从而能明确区分多音乐谱中的不同音高.其次,提出了变音记号位置注意力,以明确建立变音记号和符头的空间依赖关系.最后,针对多音符头纵向分布、音符序列横向排列、音符符头、符干和符尾呈现的局部方向性特点,提出了方向注意力模块,更好地捕捉音符特征分布的方向性.在多音乐谱数据集上开展实验,实验结果表明,该方法对时值识别的符号错误率为1.14%,对音高识别的符号错误率为2.14%.与当前基准方法卷积递归神经网络相比,该方法时值识别的符号错误率降低了0.67%,对音高识别的符号错误率降低了1.14%,对多音乐谱具有良好的识别效果.

The post-meiotic phase of male germ cell development in mammals undergoes a series of dramatic morphological changes,including acrosome and flagellum formation,nuclear condensation,and cytoplasmic exclusion,which is driven by a highly regulated sequence of biochemical reactions(Meistrich and Hess,2013).Such differentiation process called spermiogenesis consists of at least 16 sequential transition steps in mice,including steps I to 8 for round spermatids,steps 9 to 11 for elongating spermatids,steps 12 to 14 for elongated or condensed spermatids,and final steps 15 to 16 for spermatozoa(Meistrich and Hess,2013).
