作者： Pandeng Xu Shurong Li Zhao Wang zhulong shao College of Information and Control Engineering China University of Petroleum Automation school of Beijing University of Posts and Telecommunications

To solve the positon/force control problem of mobile manipulator with flexible joints, a sliding-mode-based adaptive strategy is given. Firstly, the dynamic model of mobile manipulator considering flexible joints is *** by using sliding mode approach, an adaptive controller is designed after decoupling the position and force. The controller has good robustness. It can guarantee the position error converge to zero and the boundedness of the force error. The Lyapunov stability analysis demonstrates the effectiveness of the given strategy. At last, simulation results show the feasibility of the method vividly.

C型凝集素(C-type lectins,CTLs)是广泛存在于昆虫体内一类含糖识别结构域的蛋白超家族,通常作为模式识别受体,在识别外来病原微生物并启动昆虫先天免疫过程中发挥重要功能。本研究克隆并鉴定了一条褐飞虱CTL编码基因NlCTL4(GenBank登录号:OQ032531),其c DNA序列全长936 bp,编码311个氨基酸。序列分析显示,Nl CTL4蛋白N端存在一段由21个氨基酸残基组成的信号肽,C端仅具有一个典型的糖识别结构域,属于S型CTLs。系统发育分析表明,Nl CTL4与半翅目其他昆虫的CTLs聚为一支,其中与玻璃翅叶蝉CTL亲缘关系最近。q RT-PCR分析显示,Nl CTL4基因在褐飞虱不同发育阶段和不同组织中均有表达。Nl CTL4在5龄若虫期的表达量最高,且在高龄若虫期(4~5龄)的表达量显著高于低龄若虫(1~3龄),但在雌、雄成虫中其表达量无显著差异。Nl CTL4在褐飞虱雌成虫肠道中表达量最高,脂肪体次之,在血淋巴中表达量最低。大肠杆菌(革兰氏阴性细菌)、金黄色葡萄球菌(革兰氏阳性细菌)和金龟子绿僵菌(丝状病原真菌)均能显著诱导Nl CTL4的表达水平,其中大肠杆菌和金黄色葡萄球菌在诱导36 h时Nl CTL4的表达量达到顶峰,金龟子绿僵菌接种24 h时的诱导水平最高。RNAi分析结果显示,抑制Nl CTL4表达后褐飞虱5龄若虫存活率及对金龟子绿僵菌侵染的抵御能力显著降低。本研究结果初步证实了褐飞虱Nl CTL4在宿主生长发育和免疫防御过程中发挥重要调控作用,且在开发褐飞虱RNAi抗虫和病原真菌防虫技术中具有重要的潜在应用价值。

The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.

Brain-derived neurotrophic factor is a crucial neurotrophic factor that plays a significant role in brain health. Although the vast majority of meta-analyses have confirmed that exercise interventions can increase brain-derived neurotrophic factor levels in children and adolescents, the effects of specific types of exercise on brain-derived neurotrophic factor levels are still controversial. To address this issue, we used meta-analytic methods to quantitatively evaluate, analyze, and integrate relevant studies. Our goals were to formulate general conclusions regarding the use of exercise interventions, explore the physiological mechanisms by which exercise improves brain health and cognitive ability in children and adolescents, and provide a reliable foundation for follow-up research. We used the Pub Med, Web of Science, Science Direct, Springer, Wiley Online Library, Weipu, Wanfang, and China National Knowledge Infrastructure databases to search for randomized controlled trials examining the influences of exercise interventions on brain-derived neurotrophic factor levels in children and adolescents. The extracted data were analyzed using Review Manager 5.3. According to the inclusion criteria, we assessed randomized controlled trials in which the samples were mainly children and adolescents, and the outcome indicators were measured before and after the intervention. We excluded animal experiments, studies that lacked a control group, and those that did not report quantitative results. The mean difference(MD;before versus after intervention) was used to evaluate the effect of exercise on brain-derived neurotrophic factor levels in children and adolescents. Overall, 531 participants(60 children and 471 adolescents, 10.9–16.1 years) were included from 13 randomized controlled trials. Heterogeneity was evaluated using the Q statistic and I^(2) test provided by Review Manager software. The meta-analysis showed that there was no heterogeneity among the studies(P = 0.67,

Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.
