Performance analysis of dual-hop mixed RF-FSO systems combined with NOMA.

This paper investigates the performance of hybrid radio frequency/free space optical (RF/FSO) systems combined with non-orthogonal multiple access communications technology. We examine a scenario where the source and destination are separated by a large distance, with no direct link between them. The relay, denoted R, operates using the decode-and-forward (DF) protocol.

The Effect of Left Temporal EEG Neurofeedback Training on Cerebral Cortical Activity and Precision Cognitive-Motor Performance.

The present study employed individualized magnitudes of electroencephalographic (EEG) alpha (8-12 hz) power in the left temporal (T3) region as a neurofeedback target parameter during the aiming period in pre-elite air pistol shooters to determine its effectiveness on cerebral cortical activation and performance accuracy compared to physical skill training, only. Shooting scores and EEG activity in the left and right temporal regions were collected from 20 healthy air pistol shooters (10 assigned to neurofeedback training) before and after a 16-session intervention completed within 6 weeks. Specifically, EEG low-alpha (8-10 hz), high-alpha (10-13 hz) power, and coherence obtained at the T3-Fz and T4-Fz recording sites over three consecutive 1-s intervals prior to trigger pull, were subjected to three separate 2 × 2 × 2 × 3 (Group x Hemisphere x Time x Epoch) ANOVAs.

Tacrolimus regulates extracellular vesicle secretion from T cells via autophagy-lysosomal pathway.

Extracellular vesicles (EVs) derived from T cells have been proposed to mediate intercellular communication and orchestrate immune responses. The immunosuppressive drug, tacrolimus (TAC), suppresses T cell activity; however, the impact of TAC on T cell-derived EVs remains primarily unexplored. In this study, human primary T cells purified from healthy donors were used to investigate TAC-mediated regulation of EV secretion by T cells.

Short and long-term mortality of spontaneous bacterial peritonitis in cirrhotic patients.

Spontaneous bacterial peritonitis (SBP) remains a significant concern for patients with cirrhosis. This study aims to reevaluate the trends in both short-term and long-term mortality rates associated with SBP. A retrospective cohort study was conducted using population data obtained from Taiwan's Health and Welfare Data Science Center, Ministry of Health and Welfare.

Physiological response of longfin smelt to changing temperatures and turbidities.

Coastal estuaries globally, including the San Francisco Estuary (SFE), are experiencing significant degradation, often resulting in fisheries collapses. The SFE has undergone profound modifications due to population growth, industrialization, urbanization and increasing water exports for human use. These changes have significantly altered the aquatic ecosystem, favouring invasive species and becoming less hospitable to native species such as the longfin smelt ().
