This paper proposes an accelerated algorithm for addressing distributed optimization problems in directed *** develop an accelerated asynchronous distributed Nesterov gradient descent algorithm for directed networks called ASYADND. For the considered problems, unpredictable, time-varying, and bounded. Under strong convexity and smoothness conditions, we analyze the proposed algorithm by transforming the asynchronous scheme into a synchronous counterpart. We adopt an acceleration mechanism and establish its linear convergence with the aid of the small gain theorem.

近年出土的《故贵妃萧氏玄堂志铭》涉及辽王朝中期的一些重要史实,具有很高的史料价值。撰者张幹曾在辽圣宗朝政坛担当重要角色,其笔下志主萧氏曾居皇后之位,后被废黜,又复起为贵妃,终因染疾遽逝。以骈偶构篇的《故贵妃萧氏玄堂志铭》善用典故,虽辞藻富逸,但文意隐晦。周、汉两代后妃典故及传统儒家经典,为模写贵妃萧氏懿德美行的重要取材来源。这种书写取向反映了辽王朝于族源上的比附心理,同时亦蕴含着国家教化之义。

运用VOF(volume of fluid)模型与用户自定义函数,数值模拟研究水在加热壁面上V形、梯形、方形和燕尾形凹槽微通道内的流动沸腾,分析凹槽形状对气泡成核、生长、脱离及聚并等行为的影响.研究结果表明:在热流密度为300 kW·m^(-2)时,凹槽均被激活为沸腾核化点,与其他形状凹槽相比,水在燕尾形凹槽微通道内的起始沸腾时间相对较早;在核态沸腾阶段,与梯形凹槽相比,气泡在燕尾形凹槽微通道内的生长和脱离时间分别缩短为7.50和6.70 ms,气泡脱离频率从33.8 s^(-1)提高至66.7 s^(-1),有利于水在微通道内的流动沸腾换热强化;脱离气泡在微通道内的聚并与拉伸行为增大液膜蒸发区域,气泡对液相的扰动增强,但会造成加热壁面上发生局部干涸,降低沸腾换热的稳定性与可靠性.

We mainly study the detection of arc faults in the direct current (DC) system of lithium battery energystorage power station. Lithium battery DC systems are widely used, but traditional DC protection devices areunable to achieve adequate protection of equipment and circuits. We build an experimental platform based onan energy storage power station with lithium batteries. Then, the data collection of normal current and arc-faultcurrent is completed under multiple conditions, and the waveforms of obvious and weak signals as the arc occursare presented. We analyze the principles and application range of several common spectrum-sensing methods andstudy the feasibility of applying them to the arc detection field. Finally, the covariance absolute value detectionalgorithm is selected, and the average value of the current is filtered out to make the algorithm adapt to the arcdetection field. The result shows that the detection probability in 500 sets of experimental data has reached 98%.

In spite of the tumor microenvironments responsive cancer therapy based on Fenton reaction（i.e., chemodynamic therapy, CDT） has been attracted more attentions in recent years, the limited Fenton reaction e ciency is the important obstacle to further application in clinic. Herein, we synthesized novel Fe O/MoS;nanocomposites modified by bovine serum albumin（Fe O/MoS;-BSA） with boosted Fenton reaction e ciency by the synergistic e ect of co-catalyze and photothermal e ect of MoS;nanosheets triggered by the second near-infrared（NIR II） light. In the tumor microenvironments, the MoS;nanosheets not only can accelerate the conversion of Fe;ions to Fe;ions by Mo;ions on their surface to improve Fenton reaction e ciency, but also endow Fe O/MoS;-BSA with good photothermal performances for photothermal-enhanced CDT and photothermal therapy（PTT）. Consequently, benefiting from the synergetic-enhanced CDT/PTT, the tumors are eradicated completely in vivo. This work provides innovative synergistic strategy for constructing nanocomposites for highly e cient CDT.
