We present a calculation of the strangeness and charmness contents $⟨N|\overline{s}s|N⟩$ $⟨N|\overline{c}c|N⟩$ nucleon from dynamical lattice QCD with $2+1$ flavors. The is performed overlap valence quarks on $2+1$-flavor domain-wall fermion gauge configurations. configurations are generated by RBC collaboration ${24}^{3}\ifmmode\times\else\texttimes\fi{}64$ sea-quark mass $a{m}_{l}=0.005$, $a{m}_{s}=0.04$, inverse spacing ${a}^{\ensuremath{-}1}=1.73\text{ }\text{ }\mathrm{GeV}$.

In this write-up we review and update our recent lattice QCD calculation of $B \to K^*$, $B_s \phi$, K^*$ form factors [arXiv:1310.3722]. These unquenched calculations, performed in the low-recoil kinematic regime, provide a significant improvement over use extrapolated light cone sum rule results. The fits presented here include further constraints estimates additional correlations between different factor shape parameters. We these along with Standard Model determinations Wilson...
Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address possibility accessing nucleon-to-pion (πN) TDAs from $$\bar pp \to e^ + - \pi ^0 $$ reaction with future P̄ANDA detector at FAIR facility. At high center-of-mass energy and invariant mass squared lepton pair q 2, amplitude signal channel admits...
In the digital era, prevalence of low-quality images contrasts with widespread use high-definition displays, primarily due to low-resolution cameras and compression technologies. Image super-resolution (SR) techniques, particularly those leveraging deep learning, aim enhance these for presentation. However, real-time execution neural network (DNN)-based SR methods at edge poses challenges their high computational storage requirements. To address this, field-programmable gate arrays (FPGAs)...
The proposed Circular Electron Positron Collider (CEPC) will allow precision Higgs measurements. To meet the stringent physics requirements, its vertex detector have to be constructed with state-of-the-art pixel technologies that promise high spatial resolution, low power consumption and material budget. We conducted R&D based on emerging CMOS sensor technology developed first prototype JadePix-1. In this paper, we describe structures are primarily designed evaluate impacts of diode geometry...
The study of baryon excitation spectra provides insight into the inner structure baryons. So far, most world-wide efforts have been directed towards $N^*$ and $\Delta$ spectroscopy. Nevertheless, double triple strange spectrum independent information to spectra. future antiproton experiment PANDA will provide direct access final states containing a $\bar{\Xi}\Xi$ pair, for which production cross sections up $\mu$b are expected in $\bar{p}p$ reactions. With luminosity...

In the ETOF(End-cap TOF) upgrade of BESIII, MRPC(Multi-gap Resistive Plate Chamber) detectors are used. ETOF is designed with 72 MRPCs. 24 channels signal read out from each MRPC, in which 6 neighbouring OR together Front-End Electronic(FEE) side. So 288 channel hit signals sent to trigger system for logic. The MPRC about 30 ns width after FEE. Hit stretched and data stored by TDPP (Trigger Data Pre-Processor) then ETOFT (End-cap TOF Trigger) through 10 high speed optical fiber links....
