A micro-CT-based “orientation–clustering–stiffness–damage” coupling framework for carbon-fiber/epoxy: From single-fiber scale to component-level failure prediction

Zhiyong Wu, Fang-Ping Chen, Limin Xu, Sun Wen-hai et autres

A four-order “orientation-clustering-stiffness-damage” coupling framework is proposed for 28–30 vol% carbon-fiber/epoxy short-fiber composites (7 μm nominal fiber diameter, 3–5 mm chopped length), enabling accurate cross-scale failure prediction spanning from 60 μm single-fiber interfacial debonding regions up to 300 μm component-level representative volume …

Multi-resolution field-based algorithm for autonomous robot exploration

Zhipeng Zhai, Limin Xu, Yuanbin Zhang, Guodong Zhang et autres

This paper proposes a robot autonomous exploration algorithm based on multi-resolution fields to solve the problems of low efficiency, high path repetition, and limited environmental adaptability in complex environments. First, OctoMap's layered architecture is used to create a multi-resolution voxel map. A …

Ground-state solution of quantum droplets in Bose-Bose mixtures

Wei Liu, Limin Xu

In this paper, we present a systematic study on the ground state computation of quantum droplets in homonuclear Bose-Bose mixtures, governed by the extended Gross-Pitaevskii equations (eGPEs) with Lee-Huang-Yang (LHY) corrections. This model captures the formation of self-bound droplets stabilized by the …

Frozen Gaussian sampling algorithms for simulating Markovian open quantum systems in the semiclassical regime

Limin Xu, Zhen Huang, Zhennan Zhou

Simulating Markovian open quantum systems in the semiclassical regime poses a grand challenge for computational physics, as the highly oscillatory nature of the dynamics imposes prohibitive resolution requirements on traditional grid-based methods. To overcome this barrier, this paper introduces an efficient Frozen …

An Effective Way to Generate Hydrogen and Nano Material from Hydrogen Sulfide

Xuan Kai Zhang, Abdulkareem M. AlSofi, Almohannad Alhashboul, Limin Xu

Abstract Hydrogen sulfide (H2S) is a toxic byproduct that requires treatment and conversion to useful chemicals, and thus production of hydrogen (H2) using H2S is beneficial and valuable in industry. Various technical ways have been developed focusing on splitting H2S into H2 …

Identifying a concealed substance by terahertz spectroscopy using DenseFormer combined with MultiXtract

Xia Chen, Limin Xu, Hong Yu Xiao, Dongliang Peng et autres

Terahertz fingerprints can be utilized for detecting hazardous materials. However, when used for human body security inspection, real-world conditions such as textile coverings and environmental humidity can interfere with terahertz wave propagation, leading to peak distortions that significantly impact peak matching accuracy …

Measurement of Beam-Recoil Observables $C_x$ and $C_z$ for $K^+Λ$ Photoproduction

S. Adhikari, Lei Guo, T. Chetry, Patrick Achenbach et autres

Exclusive photoproduction of $K^+ Λ$ final states off a proton target has been an important component in the search for missing nucleon resonances and our understanding of the production of final states containing strange quarks. Polarization observables have been instrumental in this …

Proton Transparency and Neutrino Physics: New Methods and Modeling

S. Dytman, M. Betancourt, Noah Steinberg, L. B. Weinstein et autres

Extracting accurate results from neutrino oscillation and cross section experiments requires accurate simulation of the neutrino-nucleus interaction. The rescattering of outgoing hadrons (final state interactions) by the rest of the nucleus is an important component of these interactions. We present a new …

Recoil Polarization in $K^+Y$ Electroproduction in the Nucleon Resonance Region with CLAS12

D.S Carman, Annalisa D'Angelo, Lucilla Lanza, V.I Mokeev et autres

Hyperon recoil polarization measurements for the exclusive electroproduction of $K^+Λ$ and $K^+Σ^0$ final states from an unpolarized proton target have been carried out using the CLAS12 spectrometer at Jefferson Laboratory. The measurements at beam energies of 6.535~GeV and 7.546~GeV span the range …
