The Born cross sections of the $e^{+}e^{-}\to\Sigma^{+}\bar{\Sigma}^{-}$ and $e^{+}e^{-}\to\Sigma^{-}\bar{\Sigma}^{+}$ processes are determined with high precision for center-of-mass energy from 2.3864 to 3.0200 GeV BESIII detector. Nonzero near threshold observed. resulting ratio effective form factors $\Sigma^{+}$ $\Sigma^{-}$ is consistent 3, agreeing incoherent sum squared charges valence quarks, but disagreeing various theoretical predictions. In addition, ratios electric magnetic...
Born cross sections for the processes $e^+e^- \to \omega\eta$ and \omega\pi^{0}$ have been determined center-of-mass energies between 2.00 3.08 GeV with BESIII detector at BEPCII collider. The results obtained in this work are consistent previous measurements but improved precision. Two resonant structures observed. In $e^{+}e^{-} sections, a resonance mass of $(2179 \pm 21 3)\text{MeV}/c^2$ width $(89 28 5)\text{MeV}$ is observed significance 6.1$\sigma$. Its properties $\phi(2170)$....
Abstract Gamma-carboxylation, catalyzed by γ-glutamyl carboxylase (GGCX), is a critical post-translational modification essential for the biological activity of vitamin K-dependent proteins (VKDPs). Mutations in GGCX, depending on their specific location, result coagulation factor deficiency type 1 (VKCFD1), which encompasses broad spectrum clinical manifestations ranging from mild to severe, including bleeding disorders, osteoporosis, and vascular calcification. The limited knowledge GGCX’s...
Overactive bladder (OAB) and female sexual dysfunction (FSD) are both common problems in women, but the association between OAB FSD lacks a large sample study. The purpose of this cross-sectional study was to investigate FSD. Data for were obtained from 2007–2016 National Health Nutrition Examination Survey (NHANES) women aged 20–59 years. qualified with aid overactive symptom score (OABSS), which by adding nocturia urge urinary incontinence score, participants total ≥ 3 considered suffer...
ABSTRACT Objective This study aims to evaluate the clinical efficacy and safety of ultrasound‐guided percutaneous septal precision chemical ablation in treatment hypertrophic obstructive cardiomyopathy (HOCM). Methods From December 2020 July 2024, 27 patients with HOCM without large target branches (diffuse multiple branches, all less than 1 mm diameter) were enrolled underwent ablation. Intraoperative left ventricular outflow tract gradient (LVOTG), postoperative cardiac troponin I (cTnI),...
Disease-modifying therapies (DMTs) that prevent immune cell infiltration into the brain have demonstrated efficacy in multiple sclerosis (MS) treatment. However, their unpredictable adverse effects necessitate development of safer therapeutic alternatives. The choroid plexus (ChP) functions as a crucial barrier against invasion, and previous studies shown preventing across ChP reduces lesion MS animal models. Understanding regulation is therefore essential for identifying novel targets MS....
Using $e^+e^-$ collision data at ten center-of-mass energies between 2.644 and 3.080 GeV collected with the BESIII detector BEPCII corresponding to an integrated luminosity of about 500 pb$^{-1}$, we measure cross sections effective form factors for process $e^{+}e^{-}\rightarrow\Xi^{0}\bar{\Xi}^{0}$ utilizing a single-tag method. A fit section pQCD-driven power function is performed, from which no significant resonance or threshold enhancement observed. In addition, ratio processes...
One of the core objectives Washington Agreement, most influential international agreement on mutual recognition degrees in engineering education, is to ensure continuous improvement professional teaching. Education for sustainable development a vital direction teaching reform and higher education. Taking Raman spectroscopy course as an example, this paper discusses VR-based design strengths limitations course. The idea computational thinking immersive learning realized by introducing VR...
The matrix effect has a major impact on energy‐dispersive X‐ray fluorescence analysis (EDXRFA) and is difficult to be evaluated due that the contents of some low‐atomic‐number elements cannot identified by in‐situ EDXRFA. Up today, fundamental parameter algorithm proposed Rousseau been widely applied correct effect. Accordingly, determining mass attenuation coefficient ( μ/ ρ ) sample key issue for algorithm. In present work, method deduce effective atomic number Z eff was studied. First,...
Following the widely use of search engines, impact Web robots have on sites should not be ignored. After analyzing navigational patterns from logs, two new algorithms are proposed. One is based classification and statistics requested URL resources, which classifies resources into eight types counts number session clients visiting records with same type. And another page member list, constructs one list for every show table visitor. The experiment shows that can detect unknown unfriendly who...

In energy dispersive X‐ray fluorescence analysis (EDXRF), many baseline estimation algorithms have been proposed for the accurate characteristic peak area. However, true value of area measured spectrum is unknown and cannot be used to evaluate accuracy algorithms. this article, an assessment method was based on Monte Carlo simulation, which can obtain area, directly. Meanwhile, practicality four were evaluated by method, include statistics‐sensitive nonlinear iterative peak‐clipping (SINP),...
