An Analytical Model for Evaluating the Hydraulic Conductivity of the Fracture‐Conduit‐Matrix System
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract In the fracture‐conduit‐matrix system, distinct shape differences among water‐conducting channels (fractures and conduits) hinder developing an analytical model for flow characteristics and hydraulic conductivity assessment. To address this, we introduce the elliptic‐conduit‐matrix model (ECMM) under velocity slip interface conditions.

Advanced Science, Volume 12, Issue 42, November 13, 2025.This study reveals the genetic and molecular mechanisms controlling the general trade‐off between phenotypic mean and plasticity of grain chalkiness in rice and identifies two major external drivers (high temperature and wide grain) and a natural major module (GCP6‐MPC5) that control this trade‐off.

Effective Meson Field Theory from QCD
, 2003 We give a simple and straightforward procedure of how to construct an effective meson Lagrangian from QCD Lagrangian. We integrate the methods of Gasser, Leutwyler, Alkofer and Reinhardt and use the derivative expansion scheme to derive the low energy effective Lagrangian for meson fields to $O(p^4)$.

Tetraquarks in the Born-Oppenheimer approximation
Journal of High Energy PhysicsThe conventional loosely bound molecule interpretation of the X(3872) is not compatible with the recent LHCb experimental measurement of the ratio of branching fractions R $$ \mathcal{R} $$ = Br(X → ψ′γ)/Br(X → ψγ). We systematically determine the entire

Nanophotonics, Volume 14, Issue 21, Page 3397-3405, 02 October 2025.Abstract The development of novel mid‐infrared (MIR) devices and systems is crucial for addressing applications in biomedical analysis, chemical reaction‐monitoring, or high‐bitrate free‐space telecommunication. Combining multiple functional elements on one chip into complex miniaturized photonic integrated circuits (PICs), is the next step in these ...

Topics in Lattice QCD and Effective Field Theory
, 2010 Effective field theories provide a formalism for categorizing low-energy effects of a high-energy fundamental theory in terms of the low-energy degrees of freedom. This process has been well established in mapping the fundamental theory of QCD in terms of the hadronic degrees of freedom, which allows for quantitative connections and predictions between

LARGE COMPONENT QCD AND THEORETICAL FRAMEWORK OF HEAVY QUARK EFFECTIVE FIELD THEORY [PDF]
International Journal of Modern Physics A, 2006 Based on a large component QCD derived directly from full QCD by integrating over the small components of quark fields with |p| < E + mQ, an alternative quantization procedure is adopted to establish a basic theoretical framework of heavy quark effective field theory (HQEFT) in the sense of effective quantum field theory.
