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.

Effect of virtual reality intervention on hospitalized patients with acute pain after thoracoscopic surgery: a pilot randomized clinical trial.

The study investigates the effectiveness of immersive virtual reality (VR) as a nonpharmaceutical approach to manage postoperative pain in patients following thoracoscopic surgery. In this single-center, triple-arm pilot randomized controlled trial (RCT), 61 postsurgical patients with a postoperative pain numerical rating scale (NRS) score ≥4 after receiving standard analgesia were included and assigned to either a quantum clinics-VR (QTC-VR) group, a Placebo-VR group, or a control group. The QTC-VR group engaged in a daily 10-minute interactive pain relief 3D-VR program, while the Placebo-VR group watched a daily 10-minute relaxation-based 2D film through VR headsets for three days following surgery.

Non-Luminal Disease Score for Everolimus in Patients with Hormone Receptor‑positive and Human Epidermal Growth Factor Receptor 2-Negative Advanced Breast Cancer: A Multicenter and Retrospective Study.

Purpose: This study aims to explore the role of the non-luminal disease score (NOLUS) for everolimus in patients with hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced breast cancer (ABC).

Methods: NOLUS has previously been established as an algorithm: NOLUS (0-100) = - 0.45 × ER(%) - 0.

Effect of Tm concentration on structure, spectral properties and cross relaxation of Tm:CaF crystal.

Through the investigation of spectral characteristics, the evolution of cluster proportions and the cross-relaxation process in Tm:CaF crystals as a function of Tm doping concentration has been clarified. A quantitative model has been established to describe the relationship between these factors. At low concentrations (0.

The disparities and development trajectories of nations in achieving the sustainable development goals.

The Sustainable Development Goals (SDGs) provide a comprehensive framework for societal progress and planetary health. However, it remains unclear whether universal patterns exist in how nations pursue these goals and whether key development areas are being overlooked. Here, we apply the product space methodology, widely used in development economics, to construct an 'SDG space of nations'.
