With the rapid development of human-computer interaction in computer aided field, EEG has become the main means of emotion recognition.Meanwhile, graph network has attracted wide attention due to its excellent ability to represent topological data.To further improve the representation performance of graph network on multi-channel EEG signals, in this paper, conside-ring the sparsity and infrequency of EEG signals, a self-adaptive brain graph convolutional network with spatiotemporal attention (SABGCN-ST) is proposed.The method solves the sparsity of emotion via the spatiotemporal attention mechanism and explores the functional connections between different electrode channels via the self-adaptive brain network topological adjacent matrix.Finally, the feature learning of graph structure is operated via graph convolution, and the emotion is predicted.Extensive experiments conduct on two benchmark datasets DEAP and SEED prove that SABGCN-ST has a significant advantage in accuracy compared with baseline models, and the average accuracy of SABGCN-ST reaches 84.91%.

Introduction: Insufficient withdrawal duration of antithrombotics leads to excessive bleeding after major surgery. We hypothesize that intraoperative hemoadsorption (HA) can reduce postoperative allogeneic transfusion requirements and excessive bleeding events (EBE), without an increase in ischemic/thromboembolic events (ITE) in patients who have taken antithrombotics and undergone nonelective cardiac surgery. Methods: A total of 460 patients admitted to our hospital from 2018 to 2022 were included in this study and divided into two groups: HA and non-HA. Because of the risk of bias due to differences in antithrombotic type, withdrawal duration, or basic coagulation function, propensity score matching was used for analyses. Results: Out of 154 cases in the HA group, 144 pairs were successfully matched. No HA safety events such as hemolysis, hypotension, or device failure occurred. After matching, the two groups were found to be comparable in preoperative antithrombotic type, withdrawal duration, platelets and coagulation function, and demographic and perioperative characteristics. Although the HA group did not have a reduced incidence of EBE, this group exhibited significant decreases in the transfusion rate and volume, the incidence of ITE, acute kidney injury, and central nervous system injury. Conclusions: For patients who have undergone nonelective cardiac surgery and taken antithrombotics, HA can simply and safely rebalance the postoperative coagulation system and have associations with reduced transfusion and postoperative ITE.

High‐detectivity and stable photodetectors (PDs) have been intensively concerned in the field of wireless optical communication, among which perovskite material has become a prospective candidate owing to its outstanding photoelectric properties. However, the defects and mismatched energy levels of perovskite material can significantly reduce the detectivity and stability of PDs. Herein, the CsPbBr2I quantum dots (CQDs) with the surface modulation via potassium trifluoroacetate (KTFA) are utilized to deserve high‐detectivity and stable PDs. The surface modulation for CQDs not only passivates defects by inhibiting vacancies, but also enhances hole transport capacity by modulating energy level mismatch. As a result, the assembled CsPbBr2I PDs show a responsivity of 0.375 A W−1, a detectivity of 1.12 × 1013 Jones and an on/off ratio of 104. More importantly, the CsPbBr2I PDs exhibit excellent long‐term stability for 12 weeks and can withstand 1000 bending cycles. This work provides a guideline for the development of perovskite in wireless optical communication. [ABSTRACT FROM AUTHOR]

Metal sulfides, such as NiCo-sulfides, have attracted tremendous attention from the view of high conductivities and electrochemical activities. However, their structure degradation during the redox process causes cycling instability, which results in the limitation of the application of metal sulfides. Herein, we study the combination of metal sulfides with carbonaceous materials. The NHCS/Ni2CoS4 composite is synthesized via a facile two-step method that entails first the fabrication of the N-doped hollow carbon spheres (NHCS) followed by the loading of Ni2CoS4 nanocubes into the NHCS via hydrothermal synthesis. The as-obtained NHCS/Ni2CoS4 composite electrode shows a super electrochemical performance (1465 F g−1 at 0.5 A g−1) and has a satisfactory cycling stability (87.4% capacitance retention). These results indicate that NHCS/Ni2CoS4 is a promising electrode material for high-performance supercapacitors. [ABSTRACT FROM AUTHOR]
