UAV selection for high-speed train communication using OTFS modulation.

Providing continuous wireless connectivity for high-speed trains (HSTs) is challenging due to their high speeds, making installing numerous ground base stations (BSs) along the HST route an expensive solution, particularly in rural and wilderness areas. This paper proposes using multiple unmanned aerial vehicles (UAVs) to deliver high data rate wireless connectivity for HSTs, taking advantage of their ability to fly, hover, and maneuver at low altitudes. However, autonomously selecting the optimal UAV by the HST is challenging.

Okra seed polysaccharides mitigate neuroinflammation and cognitive impairment via modulation of Nrf2/HO-1, HMGB1/RAGE/TLR4/NF-κB, NLRP3/Caspase-1, JAK-2/STAT-3, AMPK/SIRT1/m-TOR, PI3K/AKT/CREB/BDNF/TrkB and PERK/CHOP/Bcl-2 axes.

Global healthcare systems are under tremendous strain due to the increasing prevalence of neurodegenerative disorders. Growing data suggested that overconsumption of high-fat/high-carbohydrates diet (HFHCD) is associated with enhanced incidence of metabolic alterations, neurodegeneration, and cognitive dysfunction. Functional foods have gained prominence in curbing metabolic and neurological deficits.

Multistate cholera outbreak in Sudan amidst ongoing armed conflict, 2023-2024.

In 2023, Sudan was affected by a major cholera outbreak affected 10 states amidst armed conflict that severely disrupted the health services. This study aimed to describe the magnitude, pattern, and trend (2023-2024) of cholera outbreak in Sudan across different states. Cholera outbreak caused significant morbidity and mortality facilitated the armed conflict that hampered the response by damaging infrastructure, displacing people, and disrupting healthcare services.

The relationships between photochemical reflectance index (PRI) and photosynthetic status in radish species differing in salinity tolerance.

Since photosynthesis is highly sensitive to salinity stress, remote sensing of photosynthetic status is useful for detecting salinity stress during the selection and breeding of salinity-tolerant plants. To do so, photochemical reflectance index (PRI) is a potential measure to detect conversion of the xanthophyll cycle in photosystem II. Raphanus sativus var.

Topical Brimonidine Tartrate 0.33% Gel versus 577-nm Pro-yellow Laser for the Treatment of Post-acne Erythema: A Comparative Study.

Background: Post acne erythema (PAE) is a common sequela of inflammatory acne vulgaris resulting from the dilatation of microcapillaries within the papillary dermis, thinning of the epidermis, and release of inflammatory cytokines. The authors sought to compare the safety and efficacy of topical Brimonidine tartrate 0.33% gel versus A 577-nm pro-yellow laser for treatment of post acne erythema.
