关键词： Major depression   Emotion   EEG   Wavelet  

摘要： Objectives Patients with major depressive disorder (MDD) show attention bias to the negative emotional stimuli. We aimed at studying the EEG-correlates of unconscious expectation of angry human faces in MDD patients compared to healthy controls. Methods 128-channel EEG was recorded in MDD (23 female and 7 male) and in healthy volunteers (22 female and 8 male) while they categorized pictures as humans or animals. Half of the pictures were neutral and half were showing the faces of angry humans or animals. The pictures were preceded by cues (one for each category), which meaning was not explained to the participants. We performed the wavelet analysis of EEG recorded during the face expectation period: 1000–2000   ms from the cue onset. Results We found the emotional modulation (EM) in EEG rhythms during the expectation of angry vs. neutral faces in both groups. Statistical comparison of the spectral power using 2   ×   2 factorial design showed that the EM differences ( p   <   .05) between the groups were in the left parietal locations in 9   Hz and in 16–18   Hz, in the right parietal locations in 27–28   Hz, and in the right frontal area in 30–31   Hz. Discussion The unconscious expectation of angry vs. neutral faces resulted in EM differences between the MDD and healthy controls in the right frontal and bilateral parietal areas mostly in beta range, and also in alpha and gamma. Conclusions The EEG from the parietal locations can be a better indicator for the differences between MDD and healthy controls. Significance Unconscious emotional processing in patients may become a prospective biomarker for depression.

关键词： Differential flatness   lithium-ion battery   model predictive control   optimal charging   pseudospectral methods  

摘要： This brief paper examines the problem of optimizing lithium-ion battery management online, in a health-conscious manner. This is a computationally intensive problem. Previous work by the authors addresses this challenge by exploiting the differential flatness of Fick's law of diffusion to improve computational efficiency, but is limited by the fact that the dynamics of a full battery cell are not differentially flat, even when the individual battery electrode dynamics are. The brief paper addresses this challenge by extending the application of differential flatness to a full single particle model. In particular, we use the conservation of charge to express the flat output trajectory of one electrode as an affine function of the other electrode's flat output trajectory. In this way, we enforce differential flatness for the full battery model. This makes it possible to express the battery charge/discharge trajectory in terms of one flat output trajectory. We optimize this trajectory using a pseudospectral method. This reduces the computational cost of the optimization by about a factor of 5 compared with pseudospectral optimization alone. In addition, the robustness of the nonlinear model predictive control strategy is demonstrated in simulation by adding state-of-health parameter uncertainties.

关键词： heterogeneous computing   energy conscious scheduling   dynamic voltage scaling   duplication-based scheduling   power consumption  

摘要： Efficient task scheduling of concurrent tasks is one of the primary requirements for high-performance computing platforms. Recent advances in high-performance computing have resulted in widespread performance improvement though at the cost of increased energy consumption and other system resources. In this article, an energy conscious scheduling algorithm with controlled threshold has been developed for precedence-constrained tasks on heterogeneous cluster, which aims at lower makespan along with reduced energy consumption. Energy conscious scheduling with controlled threshold algorithm combines the benefits of dynamic voltage scaling with controlled threshold-based duplication strategy to achieve its objectives. Effectiveness of the proposed algorithm is analyzed in comparison with available duplication- and non-duplication-based scheduling algorithms (with and without dynamic voltage scaling approach) to ascertain its performance and energy consumption. Exhaustive simulation results on random and real-world graphs demonstrate that energy conscious scheduling algorithm with controlled threshold has the potential to reduce energy consumption and makespan.

关键词： 口译行为   ERP   冲突适应   认知控制   意识控制  

摘要： 虽然从认知神经心理学的视角已有研究发现(如Dehaene,van Gaal,Kiesel等)认知神经机制诸如抑制控制和任务转换等认知控制功能独立于意识,但对冲突适应是否需要意识的参与众说纷纭,争执不休。为探究这一问题,本研究从口译认知心理学的视角,记录了30名受试学生译员在完成箭头偏对比掩蔽任务(metacontrast masking task)时的口译行为和脑电数据。实验结果:在有意识和无意识条件下受试学生译员对SL信息刺激在反应时和额中N2和中顶P3波幅上均凸显了冲突适应效应。结果表明:(1)学生译员对SL常用词的信息处理无需或几乎无需意识的参与,处于零意识或低意识态势,而对SL生僻词句的信息处理不仅需要意识的参与,而且处于高度紧张的意识态势;(2)学生译员对SL信息处理的冲突控制独立于意识;(3)以前无意识经验对口译信息加工系统具有适应性调节作用。本研究不仅突显领悟口译信息认知控制和意识的本质意义,而且彰显建构认知对口译信息控制与意识关系理论的启示作用。
