The development of efficient and robust anode materials for stable alkaline seawater electrolysis is severely limited by chlorine evolution reaction and chloride ***,the sulfur-doped cobalt-nickel bimetallic phosphides(ConiPS)are specifically designed as a pre-catalyst for navigating a surface reconstruction to fabricate the anions(PO^(3-)_(4) and SO^(2-)_(4))-decorated Co(ni)OOH catalyst(R-ConiPS)with exceptional durability and high activity for stable alkaline seawater oxidation(ASO).Various experiment techniques together with theoretical simulations both demonstrate that the in situ-generated PO^(3-)_(4) and SO^(2-)_(4) anions on catalyst surface can improve the oxygen evolution reaction(OER)activity,regulating and stabilizing the catalytic active species Co(ni)OOH,as well as make a critical role in inhibiting the adsorp-tion of chloride ions and extending the service life of ***,this R-ConiPS electrode exhi-bits superb OER activity toward AsO and stands out among the non-precious ASO electrocatalysts reported recently,requiring low overpotentials of 420 and 440 mV to attain large current densities of 500 and 1000 mA cm^(-2) in an alkaline natural seawater electrolyte,***,the catalyst displays a negligible chloride corrosion at room temperature during ASO operation(>200 h)at 500 mA cm^(-2).This work opens up a new viewpoint for designing high-activity and durable electrocata-lystsforseawaterelectrolysis.

BACKGROUND Thrombocytopenia 2,an autosomal dominant inherited disease characterized by moderate thrombocytopenia,predisposition to myeloid malignancies and normal platelet size and function,can be caused by 5’-untranslated region(UTR)point mutations in ankyrin repeat domain containing 26(ANKRD26).Runt related transcription factor 1(RUNX1)and friend leukemia integration 1(FLI1)have been identified as negative regulators of ***,the positive regulators of ANKRD26 are still *** To prove the positive regulatory effect of GATA binding protein 2(GATA2)on ANKRD26 *** Human induced pluripotent stem cells derived from bone marrow(hiPSC-BM)INTRODUCTION Ankyrin repeat domain containing protein 26(ANKRD26)acts as a regulator of adipogenesis and is involved in the regulation of feeding behavior[1-3].The ANKRD26 gene is located on chromosome 10 and shares regions of homology with the primate-specific gene family *** to the Human Protein Atlas database,the ANKRD26 protein is localized to the Golgi apparatus and vesicles,and its expression can be detected in nearly all human tissues[4].Moreover,UniProt annotation revealed that ANKRD26 is localized in the centrosome and contains coiled-coil domains formed by spectrin helices and ankyrin repeats[5,6].The most common disease related to ANKRD26 is thrombocytopenia 2(THC2),which is a rare autosomal dominant inherited disease characterized by lifelong mild-to-moderate thrombocytopenia and mild bleeding[7-9].Caused by the variants in the 5’-untranslated region(UTR)of ANKRD26,THC2 is defined by a decrease in the number of platelets in circulating blood and results in increased bleeding and decreased clotting ability[8,10].Due to the point mutations that occur in the 5’-UTR of ANKRD26,its negative transcription factors(TFs),Runt related transcription factor 1(RUNX1)and friend leukemia integration 1(FLI1),lose their repression effect[11].The persistent expression of ANKRD26 increases the activi

人工智能技术引领的新一轮科技革命,在促进经济增长的同时重塑着我国收入分配格局。将国际机器人联合会(IFR)工业机器人安装数据引入明瑟工资方程,利用中国劳动力动态调查数据(CLDS),从技能偏向性、知识密集型和资本—劳动“二元”属性三个维度,分析人工智能对学历工资差距的理论机制,并进行实证检验。研究发现:第一,人工智能发展有利于提高劳动力整体工资水平,但会进一步扩大学历工资差距,经过多种稳健性检验后该结论仍然成立。第二,人工智能对高学历劳动力具有更为显著的就业创造效应,从而导致高低学历劳动力间的收入份额占比失衡,加剧学历工资差距。此外,高收入群体中的高学历劳动力更有可能从人工智能的就业创造效应中获益。第三,人工智能对学历工资差距的发散效应存在异质性,在中西部地区、女性以及老年劳动力群体中发散效应更加明显。本研究为解决人工智能冲击下的收入分配结构失衡问题提供了有益启示。

针对实际工程中存在的具有多个输出响应的高维问题,提出一种基于主动学习与贝叶斯深度神经网络的高维多输出不确定性传播方法。利用多个输出响应对应同一组输入变量的特点,对输入变量进行一次性采样,从而构造初始训练样本集。采用贝叶斯深度神经网络初步构建高维多输出问题的代理模型。贝叶斯深度神经网络能够同时求解多个预测输出响应的不确定性估计,基于该特点发展了一种针对高维多输出问题的主动加点策略,通过主动学习的方式进一步构建具有较高精度的高维多输出代理模型。然后,利用蒙特卡罗采样方法以及高斯混合模型求解多个输出响应的联合概率密度函数。研究结果表明,所提方法不仅能够避免分别对多个输出响应进行独立求解的复杂过程,而且能够利用多个输出响应之间的关联,主动筛选关键样本点进行建模,在一定程度上提高了高维多输出问题的求解效率。最后,通过几个数值算例验证了所提方法的有效性。

Enhancing the quality of junctions is crucial for optimizing carrier extraction and suppressing recombination in semiconductor devices. In recent years, metal halide perovskite has emerged as the most promising next-generation material for optoelectronic devices. However, the construction of high-quality perovskite junctions, as well as characterization and understanding of their carrier polarity and density,remains a challenge. In this study, using combined electrical and spectroscopic characterization techniques,we investigate the doping characteristics of perovskite films by remote molecules, which is corroborated by our theoretical simulations indicating Schottky defects consisting of double ions as effective charge *** a post-treatment process involving a combination of biammonium and monoammonium molecules, we create a surface layer of n-type low-dimensional perovskite. This surface layer forms a heterojunction with the underlying 3D perovskite film, resulting in a favorable doping profile that enhances carrier extraction. The fabricated device exhibits an outstanding open-circuit voltage(VOC) up to 1.34 V and achieves a certified efficiency of 19.31% for single-junction wide-bandgap（1.77 eV） perovskite solar cells, together with significantly enhanced operational stability, thanks to the improved separation of carriers. Furthermore, we demonstrate the potential of this wide-bandgap device by achieving a certified efficiency of 27.04% and a VOCof 2.12 V in a perovskite/perovskite tandem solar cell configuration.
