We propose and experimentally demonstrate a bidirectional measurement for Brillouin optical correlation domain analysis as a novel and simple way of the performance enhancement. Brillouin gain and loss spectra of two adjacent correlation peaks are simultaneously and independently analyzed by applying midpoint attenuation in a fiber under test, which doubles both the speed and the range of the distributed measurement.

Purpose/objective: The present review examined the evidence for a potentially bidirectional association between mobility function and cognitive function in midlife and older adulthood.
Research Method/design: In 2023-2024, we conducted a scoping review by carrying out systematic searches on Google Scholar, PubMed, and PsycINFO for articles that included measures of mobility function and cognitive function.
Results: Of the 1,504 articles screened, 40 were included for review.

Based on the bidirectional electromigration (BIEM) technique, a corrosion inhibitor solution was prepared by mixing 1 mol/L triethylene tetramine with deionized water. The effects of current density, charging time, and corrosion inhibitor on critical current density and hydrogen content of rebar were investigated. Subsequently, the hydrogen embrittlement risk of rebar was further characterized by mechanical property tests.

Further, the relative contribution of such non-genetic elements in identical twins have not been characterized. Here, we aimed to measure differentiating host and microbial biomarkers of RA by studying MZ twins discordant for disease using a multi-omics approach.

Pollution caused by environmental problems has aggravated the problem of resource scarcity, and the destruction of the ecological environment by mankind has shown serious consequences. Countries around the world are actively launching various carbon emission reduction and energy transformation policies to face this predicament. This paper investigates the risk spillover effects of China's carbon trading market with China's energy market and the U.

Objective: Post-stroke depression (PSD) affects approximately 40% of stroke survivors, with cognitive deficits being frequently observed. Transcranial Direct Current Stimulation (tDCS) has shown promise in improving cognitive performance in stroke patients. We explored the effects of tDCS on cognitive performance in PSD.
