A bstract We present an improved calculation of the HHV ( H = D s ) , B V ρ K * ω and ϕ coupling constants g beyond leading order in α from QCD light-cone sum rules (LCSRs) by means distribution amplitudes (LCDAs) light vector mesons. Near light-cone, next-to-leading corrections for vacuum-to-vector-meson correlation function are included at power δ m / Q b c within framework hard-collinear factorization. The higher-twist two-particle three-particle meson LCDAs systematically incorporated...
For the purpose of developing new drugs and repositioning existing ones, accurate drug-target affinity (DTA) prediction is essential. While graph neural networks are frequently utilized for DTA prediction, it difficult single-scale to access global structure compounds. We propose a novel model in this study, MAPGraphDTA, which uses an approach based on multi-head linear attention mechanism that aggregates features weights multi-scale gated power captures multi-hop connectivity relationships...
Abstract We study the semileptonic decays using PQCD factorization approach with newly defined distribution amplitudes of meson and a new kind parametrization for extrapolating form factors which takes into account recent lattice QCD results. find following main results: (a) predictions branching ratios are smaller by about 5%-16% when results taken in extrapolation relevant factors; (b) ratio longitudinal polarization , ; (c) after including results, theoretical slightly change: . The agree...

We calculated branching ratios ${\cal B}(B_{(s)} D_{(s)}^{(*)} l \nu_l )$ $l=(e,\mu.\tau)$ $R(D^{(*)})$ and $R(D_s^{(*)} other physical observables $P_\tau(D_{(s)}^{(*)})$, $F_L(D^*_{(s)})$ $A_{FB}(\tau)$. The "PQCD+Lattice" predictions for...

We present an improved calculation of the $D_{(s)}^*D_{(s)}V$ and $B_{(s)}^*B_{(s)}V$ coupling constants, where $V$ denotes $\rho$, $K^\ast$, $\omega$, $\phi$ meson. These couplings govern QCD long-distance dynamics in interactions between heavy pseudoscalar/vector mesons light vector mesons. Our analysis is conducted within framework light-cone sum rules (LCSRs) by utilizing distribution amplitudes (LCDAs) By systematically incorporating subleading power corrections higher-twist...
Proteins play crucial roles in biological processes, with therapeutic peptides emerging as promising pharmaceutical agents. They allow new possibilities to leverage target binding sites that were previously undruggable. While deep learning (DL) has advanced peptide discovery, generating D-proteins composed of D-amino acids remains challenging due the scarcity natural examples. This paper proposes D-Flow, a full-atom flow-based framework for {de novo} D-peptide design. D-Flow is conditioned...
We present an improved calculation of the $HHV$ ($H=D_{(s)},\, B_{(s)}$, $V= \rho$, $K^\ast$, $\omega$, and $\phi$) coupling constants $g_{HHV}$ beyond leading order in $\alpha_s$ from QCD light-cone sum rules (LCSRs) by means distribution amplitudes (LCDAs) light vector mesons. Near light-cone, next-to-leading corrections for vacuum-to-vector-meson correlation function are included at power $\delta_V = m_V/m_Q$ ($Q=b,c$) within framework hard-collinear factorization. The higher-twist...
