The characteristics of WM in individuals with depressive tendencies: A functional near-infrared spectroscopy (fNIRS) study.

Individuals with depressive tendencies are considered to be at high risk for the onset of depressive disorders. Currently, most research focuses on the impairment of working memory in patients with depression, while there is less attention paid to the WM of individuals with depressive tendencies, and their neural mechanisms underlying it are poorly understood. Therefore, this study focuses on the characteristics and neural mechanisms of WM in individuals with depressive tendencies.

Comprehensive Simulation Framework for Space-Air-Ground Integrated Network Propagation Channel Research.

The space-air-ground integrated network (SAGIN) represents a pivotal component within the realm of next-generation mobile communication technologies, owing to its established reliability and adaptable coverage capabilities. Central to the advancement of SAGIN is propagation channel research due to its critical role in aiding network system design and resource deployment. Nevertheless, real-world propagation channel research faces challenges in data collection, deployment, and testing.

Fisher-Information-Matrix-Based USBL Cooperative Location in USV-AUV Networks.

With the development of underwater technology and the increasing demand for ocean development, more and more intelligent equipment is being applied to underwater scientific missions. Specifically, autonomous underwater vehicle (AUV) clusters are being used for their flexibility and the advantages of carrying communication and detection units, often performing underwater tasks in formation. In order to locate AUVs with high precision, we introduce an unmanned surface vehicle (USV) with global positioning system (GPS) and propose a USV-AUV network.

Blind beamforming-based strong interference suppression in underwater acoustic direct-sequence code-division multiple-access systems.

In an underwater acoustic direct-sequence code-division multiple-access (DS-CDMA) system, the performance of the conventional receiver is severely limited by the strong multiple-access interferences, which is due to the near-far effect. In this paper, a time-frequency-time with eigendecomposition-based blind beamformer (TFT-EBB) method is proposed for a distant user to suppress strong interference from a nearby user in DS-CDMA underwater acoustic communications. When the interference level is moderately higher than that of the desired signal, the TFT-EBB method can estimate the composite steering vector of all multipath components of the weak desired user signal via the eigendecomposition of the array covariance matrix at each frequency bin.

[Study on metabolism of Coptis chinensis alkaloids from different compatibility of Wuji Wan in human intestinal flora].

Objective: To study the metabolism of berberine and palmatine in prescription compatibility of Wuji Wan in human intestinal flora.

Method: The L9 (3(4)) orthogonal design was adopted to compare prescription compatibility of nine groups of Wuji Wan composed of Coptis chinensis, Evodiae and fried Radix paeoniae alba into and single ingredient of C. chinensis.

[Studies on intestinal absorption of alkaloids in Coptis chinensis by in situ single-pass perfused rat intestinal model].

Objective: To study the absorption characteristics of alkaloids in Coptis chinensis in rat intestinal.

Method: In situ single-pass perfused rat intestinal model was used and the concentrations of berberine and palmatine were determined by HPLC, the drug absorption rate constant (K(a)) and apparent absorption coefficient (P(app)) were tested to evaluate their absorption characteristics.

Result: The absorption of berberine and palmatine in different regions of rat intestinals was significantly different.

[Preventive and therapeutic effects of Bushen Huoxue Recipe on autoimmune premature ovarian failure in mice].

Objective: To investigate the preventive effect of Bushen Huoxue Recipe (BSHXR), a compound traditional Chinese herbal medicine, on autoimmune premature ovarian failure (POF) in mice.

Methods: Ovarian antigen was prepared with the ovarian tissue of female BALB/c mice. A mouse model of POF was established by immunization injection of the ovarian antigen of isotype female mice on multiple subcutaneous sites and two posterior soles.
