Precise Measurement of the e^{+}e^{-}→D_{s}^{+}D_{s}^{-} Cross Section at Center-of-Mass Energies from Threshold to 4.95 GeV.

Using the e^{+}e^{-} collision data collected with the BESIII detector operating at the BEPCII collider, at center-of-mass energies from the threshold to 4.95 GeV, we present precise measurements of the cross section for the process e^{+}e^{-}→D_{s}^{+}D_{s}^{-} using a single-tag method. The resulting cross section line shape exhibits several new structures, thereby offering an input for a future coupled-channel analysis and model tests, which are critical to understand vector charmonium-like states with masses between 4 and 5 GeV.

The efficacy and safety of PD-1 inhibitors combined with chemotherapy treatment for advanced esophageal cancer: a network meta-analysis.

Objective: This study systematically evaluated the efficacy of programmed death 1 (PD-1) inhibitors combined with chemotherapy for advanced esophageal cancer (EC).

Methods: PubMed, Embase, Web of Science, Scopus, and Cochrane Library were searched to identify related randomized controlled trials (RCTs).

Results: Seven RCTs involving 4,363 participants were included.

Enhanced Photocatalytic Degradation of Chlorsulfuron by MoS/MIL101(Fe) S-Scheme Heterojunction: A Conversion Mechanism Dominated by Electrons and Long-Lifetime Reactive Species.

Altering the generation route of reactive species is a potent means to augment the photocatalytic activity. In this study, MoS/MIL-101(Fe) S-scheme heterojunction (MF2) is prepared using a water/solvent thermal method for photocatalytic degradation of chlorsulfuron. Driven by the internal electric field, the local electron density of MF2 is redistributed, thus enhancing the adsorption of O.

Online monitoring of water quality in industrial wastewater treatment process based on near-infrared spectroscopy.

Water quality monitoring is one of the critical aspects of industrial wastewater treatment, which is important for checking the treatment effect, optimizing the treatment technology and ensuring that the water quality meets the standard. Chemical oxygen demand (COD) is a key indicator for monitoring water quality, which reflects the degree of organic matter pollution in water bodies. However, the current methods for determining COD values have drawbacks such as slow speed and complicated operation, which hardly meet the demand of online monitoring.

Multi-Omics Insights into Regulatory Mechanisms Underlying Differential Deposition of Intramuscular and Abdominal Fat in Chickens.

Excessive abdominal fat deposition in chickens disadvantages feed conversion, meat production, and reproductive performance. Intramuscular fat contributes to meat texture, tenderness, and flavor, serving as a vital indicator of overall meat quality. Therefore, a comprehensive analysis of the regulatory mechanisms governing differential deposition of abdominal versus intramuscular fat is essential in breeding higher-quality chickens with ideal fat distribution.
