Major depressive disorder(MDD)is characterized by emotion dysregulation.Whether implicit emotion regulation can compensate for this deficit remains unknown.In this study,we recruited 159 subjects who were healthy controls,had subclinical depression,or had MDD,and examined them under baseline,implicit,and explicit reappraisal conditions.Explicit reappraisal led to the most negative feelings and the largest parietal late positive potential(parietal LPP,an index of emotion intensity)in the MDD group compared to the other two groups;the group difference was absent under the other two conditions.MDD patients showed larger regulatory effects in the LPP during implicit than explicit reappraisal,whereas healthy controls showed a reversed pattern.Furthermore,the frontal P3,an index of voluntary cognitive control,showed larger amplitudes in explicit reappraisal compared to baseline in the healthy and subclinical groups,but not in the MDD group,while implicit reappraisal did not increase P3 across groups.These findings suggest that implicit reappraisal is beneficial for clinical depression.

The high-accuracy drag-free control is one of the key technologies for gravity gradient satellites.Since the range of the gravity gradiometer is limited, the measurement is subject to the saturation constraint.This paper introduces a design method of the adaptive drag-free control law by employing the set-valued identification approach. By inserting several thresholds in the constrained interval, the output observation is transformed into the set-valued information under different thresholds, based on which and the weighted optimization technique the identification algorithm for the unknown parameter is constructed. The adaptive drag-free control law is designed via the certainty equivalence principle. It is shown that the identification algorithm is strongly convergent and the convergence rate of the estimation error is obtained. The performance of the closed-loop system is analyzed, and the asymptotic optimality of the adaptive controller is proved. The numerical simulation is included to verify the effectiveness of the main results.

School-age children are in a specific development stage corresponding to juvenility,when the white matter of the brain experiences ongoing maturation.Dffusion-weighted magnetic resonance imaging(DWI),especially diffusion tensor imaging(DTI),is extensively used to characterize the maturation by assessing white matter properties in vivo.In the analysis of DWI data,spatial normalization is crucial for conducting inter-subject analyses or linking the individual space with the reference space.Using tensor-based registration with an appropriate diffusion tensor template presents high accuracy regarding spatial normalization.However,there is a lack of a standardized diffusion tensor template dedicated to school-age children with ongoing brain development.Here,we established the school-age children diffusion tensor(SACT)template by optimizing tensor reorientation on high-quality DTI data from a large sample of cognitively normal participants aged 6-12 years.With an age-balanced design,the SACT template represented the entire age range well by showing high similarity to the age-specific templates.Compared with the tensor template of adults,the SACT template revealed significantly higher spatial normalization accuracy and inter-subject coherence upon evaluation of subjects in two different datasets of schoolage children.A practical application regarding the age associations with the normalized DTI-derived data was conducted to further compare the SACT template and the adult template.Although similar spatial patterns were found,the SACT template showed significant effects on the distributions of the statistical results,which may be related to the performance of spatial normalization.Looking forward,the SACT template could contribute to future studies of white matter development in both healthy and clinical populations.The SACT template is publicly available now(tp://igshare com/aricles/dataseu'SACT_.template/14071283).

为使前后风轮间流场干涉影响降低,双风轮风电机组传动链具有跨距长、支撑点多的特性,导致双风轮风电机组传动链在长跨距柔性主机架支撑下具有复杂的载荷特性。建立考虑主机架柔性的某型双风轮风电机组传动链动力学模型,分析齿轮与主机架结构强度。结果表明:各级齿轮接触强度、弯曲强度以及主机架强度均满足设计要求;主机架支撑变形有助于协调各构件之间的相对变形,适量减小主机架柔性有助于改善传动链承载时主轴轴承之间的轴线不对中情况。

高海拔寒区隧道围岩内部裂隙水的冻结膨胀会对隧道结构的安全产生重要影响。基于寒区隧道衬砌背后积水冻胀理论建立高海拔寒区公路隧道地层结构模型,研究了隧道衬砌背后积水冻胀过程中围岩与支护结构相互作用关系演变,分析了不同冻胀率下空洞储水冻胀对衬砌应力分布和结构变形的影响。研究结果表明:衬砌最大主应力随冻胀率的增大而增加,在冻胀率为6%时达到峰值;冻胀率低于5%时,冻胀对结构的最小主应力的影响不大,结构开裂后冻胀对结构最小主应力的影响显著;V级围岩隧道储水空洞向围岩侧的冻胀变形大于向衬砌侧的变形,且冻胀率越小,向围岩侧变形量的占比越大。在寒区隧道的设计和施工中要充分重视衬砌背后空洞的处置,衬砌和围岩紧密贴合可有效减弱衬砌背后积水冻胀压力。

The human brain undergoes rapid development during childhood,with significant improvement in a wide spectrum of cognitive and affective functions.Mapping domain-and age-specific brain activity patterns has important implications for characterizing the development of children’s cognitive and affective functions.The current mainstay of brain templates is primarily derived from structural magnetic resonance imaging(MRI),and thus is not ideal for mapping children’s cognitive and affective brain development.By integrating task-dependent functional MRI data from a large sample of 250 children(aged 7 to 12)across multiple domains and the latest easy-to-use and transparent preprocessing workflow,we here created a set of age-specific brain functional activity maps across four domains:attention,executive function,emotion,and risky decision-making.Moreover,we developed a toolbox named Developmental Brain Functional Activity maps across multiple domains that enables researchers to visualize and download domain-and age-specific brain activity maps for various needs.This toolbox and maps have been released on the Neuroimaging Informatics Tools and Resources Clearinghouse website(http://***/projects/dbfa).Our study provides domain-and age-specific brain activity maps for future developmental neuroimaging studies in both healthy and clinical populations.

目的分析焦虑、抑郁情绪对艾滋病患者抗病毒治疗免疫学失败的影响,并提出相应的心理干预策略。方法回顾性分析2021年2月至2022年2月北京某医院收治的200例接受抗病毒治疗的艾滋病患者的临床资料,根据抗病毒治疗后的免疫应答情况将其分为成功组和失败组。比较两组的基础资料与治疗前心理状态,统计两组的焦虑自评量表(SAS)、抑郁自评量表(SDS)评分,采用单因素、多因素Logistic回归分析影响艾滋病患者抗病毒治疗免疫学失败的因素,绘制受试者工作特征(ROC)曲线,分析SAS、SDS评分及二者联合预测艾滋病患者抗病毒治疗免疫学应答失败的临床价值。结果200例艾滋病患者抗病毒治疗后免疫学失败率为21.00%(42/200)。失败组性别、年龄、世界卫生组织临床分期、服药依从性及是否合并焦虑、抑郁与成功组比较,差异具有统计学意义(P1,P<0.05)。失败组SAS、SDS评分高于成功组(P<0.05);ROC曲线结果显示,SAS、SDS评分及二者联合预测艾滋病患者抗病毒治疗免疫学应答失败的曲线下面积分别为0.734、0.724、0.768。结论艾滋病患者抗病毒治疗后仍有部分患者出现免疫学失败,原因多与性别、年龄、世界卫生组织临床分期、服药依从性、焦虑与抑郁情绪相关,且SAS评分联合SDS评分可有效预测艾滋病患者抗病毒治疗免疫学应答的失败。

This work investigates the input-to-state stability(ISS)problem for impulsive switched singular systems(ISSSs)with mismatched disturbances.In this paper,‘disturbance’is a general concept that includes model uncertainty,unknown system dynamic,external disturbance,etc.The modified uncertainty and disturbance estimator(UDE)-based control method is presented for singular systems and ISSSs,a virtual control is introduced to offset the effects of mismatched disturbances.On the basis of a discontinuous multiple Lyapunov functional and admissible edge-dependent average dwell time(AED-ADT)method,several sufficient conditions in terms of linear matrix inequalities(LMIs)are obtained to ensure that the closed-loop systems are regular,impulse-free and ISS.Finally,two examples are given to demonstrate the effectiveness of the proposed results.
