A series of Monte Carlo and HydroLight radiative transfer simulations are used to demonstrate that the traditional form of the Fresnel transmission across the water-air interface is accurate. This contradicts assertions to the contrary in a recent paper [Opt. Express25, 27086 (2017)10.1364/OE.25.027086] that suggested that the impact of multiple surface interactions had previously been ignored and that the transmission factor was dependent upon the turbidity of the water.

Carbapenem- and colistin-resistant Escherichia coli (CCREC) cause high mortality rates and health costs, and have become serious health concerns. Total 1764 samples were collected from 60 animal farms in 2019 and 2021, including worker and animal faeces, wastewater, well water, air, vegetables, human hands, object surfaces, throat swabs, soil, and flies to investigate the prevalence and potential transmission pathways of CCREC. Eleven CCREC were detected: 9 (5 in 2019 and 4 in 2021) from 5 worker faeces, 3 animal faeces, 1 wastewater, and 2 from 1 flies sample.

Article Synopsis
- A groundbreaking two-way fifth-generation (5G) system combining free-space optical (FSO), hollow-core fiber (HCF), and underwater wireless optical communication (UWOC) has been successfully developed, showcasing high-speed and long-distance data transfer.
- This system utilizes red/green/blue (R/G/B) wavelengths and a spatial light modulator (SLM) for improved transmission rates, as well as to counteract misalignments caused by movement in drones or ocean currents.
- Tests over a 1-km FSO, 10-m HCF, and 10.44-m underwater environment achieved impressive data rates of 9.1 Gb/s upstream and 24 GHz downstream with low error rates, indicating significant
Exceptions to the rule: When does resistance evolution not undermine antibiotic therapy in human bacterial infections?

The use of antibiotics to treat bacterial infections often imposes strong selection for antibiotic resistance. However, the prevalence of antibiotic resistance varies greatly across different combinations of pathogens and drugs. What underlies this variation? Systematic reviews, meta-analyses, and literature surveys capable of integrating data across many studies have tried to answer this question, but the vast majority of these studies have focused only on cases where resistance is common or problematic.

A novel underwater polarization orientation method is proposed based on direct sunlight compensation. Firstly, based on the polarization transmission model at the water-air interface, the interference mechanism of the underwater direct sunlight polarization detection model was analyzed.

The progress of solar-driven water-splitting technology has been impeded by the limited light response capability of semiconductor materials. Despite attempts to leverage nearly 50% of infrared radiation for photothermal synergy and catalytic reaction enhancement, heat loss during liquid phase reactions results in low energy conversion efficiency. Here, the photothermally driven catalytic water-splitting system, which designs K-SrTiO -loaded TiN silica wool at the water-air interface.
