Lattice-data-driven specific heat and isentropic bulk modulus of SU(3) gluon matter at finite temperature

Abstract We investigate the specific heat and isentropic bulk modulus of finite-temperature pure SU(3) gauge matter within a lattice-data-driven phenomenological framework. The equation of state is formulated in terms of a temperature-dependent effective gluon mass constrained by...

Achieving breakthrough high strength in AZ31 magnesium alloy bar via a novel single-pass extrusion process

AZ31 magnesium alloy generally suffers from insufficient room-temperature strength. Meanwhile, conventional processing routes offer limited strengthening efficiency, and severe plastic deformation (SPD) processes face difficulties in industrial upscaling. To address these bottlen...

The correlation between the gyrB genetic distance and the digital DNA-DNA hybridization value for the genus Micromonospora and taxonomic studies on Micromonospora cynarae sp. nov

An early study on Micromonospora species indicated that a gyrB (DNA gyrase subunit B) genetic distance about 0.014 would equal to the 70% value in DNA hybridization value. However, based on the corresponding relation of gyrB genetic distance and dDDH (digital DNA–DNA hybridizatio...

Experimental study on shear performance of wet joints with free-form surface shear keys in bridges

Wet joints in precast bridge decks are subjected to complex stresses and are vulnerable to cracking, with interface shear being a major damage mechanism. This study proposes a parametrically generated free-form surface shear key based on an even quartic interpolation profile. Hyb...

Experimentally Informed Numerical Modelling of Cementitious Grout-Jacketed RC Columns with Layered Freeze–Thaw Damage

Freeze–thaw deterioration in jacketed reinforced concrete (RC) columns is spatially non-uniform, yet this depth-dependent damage is rarely represented explicitly in structural simulations. This study develops an experimentally informed numerical modelling framework for cementitio...

Catalytic Network states Govern Programmable Analytical Functions in a Multifunctional Nanozyme

Abstract Although multifunctional nanozymes enable diverse analytical applications, existing activity-based models cannot adequately explain how a single nanozyme is programmably reconfigured to perform distinct analytical functions under different reaction conditions. Here, we s...

Multidimensional Analysis of Ore Spontaneous Combustion Tendency Based on IAHP and Improved Interval Approximation

Influence of Homoring Competition Effect of Substituents on the NMR Chemical Shifts in Resonance‐Assisted Hydrogen Bond for 2‐Hydroxyl Diaryl Schiff Bases

ABSTRACT In multi‐substituent organic compounds, the interaction mechanism among groups is of great significance for understanding and predicting the properties of compounds. The homoring competition effect remains largely unexplored. This work rigorously investigates how this ef...

Multi-process regulation of surface residual stress for improving SCC resistance of Al-Zn-Mg-Cu alloy high-lock nuts

Aerospace high-lock nuts, as core aircraft fasteners, face severe stress corrosion cracking (SCC) risks during long-term service, threatening flight safety. This study investigates the effects of closing, stress relief aging and shot peening on residual stress, SCC resistance and...

scGSI: Graph-guided self-supervised integration of paired single-cell multi-omics

Paired single-cell multi-omics technologies provide direct within-cell correspondence across molecular layers and offer a powerful route to dissecting cellular heterogeneity and regulatory relationships. However, effective integration requires more than modality mixing: a useful...

Research Status and Development Trend of Materials for Coal Spontaneous Combustion Prevention and Control: A Review

Coal is a core fossil energy resource that has long dominated the primary energy consumption system, serving as a key driver of the global industrialization process and economic growth. During coal mining operations, coal spontaneous combustion occurs frequently, seriously threat...

Observation of Highly Efficient Electric-Quadrupole Second Harmonic Generation in a Dirac Semimetal

Abstract Topological semimetals hold great promise for nonlinear optics (NLO). It is challenging to probe tilted Dirac fermion-driven intrinsic second harmonic generation (SHG) and topological band structure modulation of second-order nonlinearity in spatial inversion and time-re...

A Residual Driven Multiscale Method for Darcy’s Flow in Perforated Domains

In this paper, we present a residual-driven multiscale method for simulating Darcy flow in perforated domains, where complex geometries and highly heterogeneous permeability make direct simulations computationally expensive. To address this, we introduce a velocity-pressure elimi...

Spiro‐Configured Self‐Assembling Molecule Modulates Phase Distribution at the Buried Interface for Efficient Sky‐Blue Perovskite LEDs

ABSTRACT Quasi‑two‑dimensional (quasi‑2D) perovskites are promising candidates for efficient blue perovskite light‑emitting diodes (PeLEDs), but their complex low‑dimensional phase distributions often result in non‑radiative recombination and emission broadening. Herein, we desig...
