Rothmund-Thomson syndrome (RTS) is an autosomal recessive disorder associated with increased predisposition to osteosarcoma. Children RTS typically present a characteristic skin rash (poikiloderma), small stature, and skeletal dysplasias. Mutations in the RECQL4 gene, which encodes RecQ DNA helicase, have been reported few patients. We examined whether developing osteosarcoma among international cohort of patients was distinctive pattern mutations gene.We obtained clinical information about...
Carbon dots (CDs) have garnered extensive interest in basic physical chemistry as well biomedical applications due to their low cost, good biocompatibility, and great aqueous solubility. However, the synthesis of multi-functional carbon has always been a challenge for researchers. Here, we synthesized novel CDs with high quantum yield 28.2% through straightforward hydrothermal method using Diaminomaleonitrile Boc-D-2, 3-diaminopropionic acid. The size, chemical functional group,...
We present results of few-layer graphene synthesis directly on SiO2/Si substrate by negative carbon ion implantation in Ni catalyst films the top substrate. Negative ions at 20 keV were implanted into with doses (4–16) × 1015 cm−2. The atoms dissolved an elevated temperature and diffused towards both sides film. After annealing, layers observed surface SiO2 beneath Formation insulating substrates was achieved etching layer.
Based on J/ψ events collected with the BESIII detector, corresponding Monte Carlo samples, tracking efficiency and its systematic uncertainty are studied using a control sample of → pp̅π+π−. Validation methods different factors influencing presented in detail. The for protons pions transverse momentum polar angle dependence also discussed.
Using $5.8 \times 10^7 J/\psi$ events collected in the BESII detector, radiative decay $J/\psi \to \gamma \phi K^+ K^- K^0_S K^0_L$ is studied. The $\phi\phi$ invariant mass distribution exhibits a near-threshold enhancement that peaks around 2.24 GeV/$c^{2}$. A partial wave analysis shows structure dominated by $0^{-+}$ state ($\eta(2225)$) with of $2.24^{+0.03}_{-0.02}{}^{+0.03}_{-0.02}$ GeV/$c^{2}$ and width $0.19 \pm 0.03^{+0.06}_{-0.04}$ product branching fraction is: $Br(J/\psi...
The exclusive Born cross sections of the production D0, D+ and mesons in e+e− annihilation at 13 energy points between 3.970 4.260 GeV are obtained by applying corrections for initial state radiation vacuum polarization to observed measured CLEO-c experiment. Both statistical systematic uncertainties estimated.
BESIII is a multipurpose spectrometer optimized for physics in the tau-charm energy region. Both detector and accelerator are undergoing an upgrade program, that will allow to run until 2029. A major replacement of inner drift chamber with new based on Cylindrical Gas Electron Multipliers improve both secondary vertex reconstruction radiation tolerance. The CGEM-IT be composed three coaxial layers cylindrical triple GEMs, operating Ar$\,$+$\,$iC$_4$H$_{10}$ (90:10) gas mixture field gain...
Abstract Background The Cylindrical Gas Electron Multiplier Inner Tracker (CGEM-IT) is one of the candidates for replacement current BESIII inner drift chamber, which has developed serious aging effects due to beam-related backgrounds. Purpose To build a full digitization model, it necessary understand electron behavior and signal induction. Methods A simulation study based on Garfield++ ANSYS software been performed. Results Parameters describing Lorentz angle, diffusion effect, time,...
Abstract The extant literature has shown that “control privatisation” (CP) can improve corporate performance. There is little evidence, however, on how CP affects This paper investigates this issue from the perspective of tax planning. Using a difference-in-differences (DID) model with paired samples as control group, we examine whether aggressiveness changes after CP. results suggest CP, corporations exhibit increased compared sample. Further, sample, central government owned does not...
Considering the aging effects of existing Inner Drift Chamber (IDC) BES\uppercase\expandafter{\romannumeral3}, a GEM based inner tracker is proposed to be designed and constructed as an upgrade candidate for IDC. This paper introduces full simulation package CGEM-IT with simplified digitization model, describes development softwares cluster reconstruction track fitting algorithm on Kalman filter method CGEM-IT. Preliminary results from algorithms are obtained using Monte Carlo sample single...
The reconstruction of charged particle trajectories in tracking detectors is a key problem the analysis experimental data for high-energy and nuclear physics. amount modern experiments so large that classical methods, such as Kalman filter, cannot process them fast enough. To solve this problem, we developed two neural network algorithms based on deep learning architectures track recognition pixel strip-based detectors. These are TrackNETv3 local (track by track) RDGraphNet global (all...
ObjectiveGynecological cancer-related lower extremity lymphedema (GC-LEL), a chronic, progressive condition, lacks standardized treatment. Currently, Supraclavicular vascularized lymph node transfer (SC-VLNT) is favoured approach in the treatment of lymphedema, and there trend toward combination technology. This study conducts comparative analysis three techniques for treating GC-LEL with simultaneous SC-VLNT liposuction.MethodsA cohort 35 patients was examined, comprising thirteen underwent...
Abstract Stable operation of the detector is essential for high quality data taking in energy physics experiments. But it not easy to keep always running stably, especially during period an environment with beam-induced background. In BESIII experiment, serious beam-related background can cause instability voltages drift chamber, innermost sub-detector. This could result decrease gain and wrong d E /d x measurements. The relationship between measurement change voltage has been studied. To...
