This study investigates how different carbon-containing absorbents affect the transient phase change expansion of liquid oxygen. Specifically, we prepared 3 types of liquid oxygen charges with varying carbon contents (0,...

During tunnel construction using the drilling and blasting method, layered jointed rock masses often pose engineering challenges such as over- and under-excavation of the crown and working face. The authors addressed the...

In underground mining and tunneling projects, directional fracture-controlled blasting is critical for precise tunnel formation and reducing over- and under-excavation. However, the presence of well-developed joints in r...

Refined delay blasting using digital electronic detonators has been widely used in rock breaking engineering, where notched borehole could control the direction of explosion-induced crack propagation. This study investig...

Abstract This study presents a numerical framework for analyzing dispersion and wave propagation in spatiotemporally modulated metamaterials. A one-dimensional periodic spring–mass system with space- and time-dependent...

This paper presents a combined numerical and empirical investigation of how propagation channel conditions shape Modulation Error Ratio (MER) in UHF DVB-T broadcasting. A MATLAB/Simulink DVB-T physical-layer model is ext...

During public health emergencies, the spread of online rumors can easily trigger public panic and anxiety, exacerbating their negative social impact. How to precisely regulate the dissemination of rumors in cyberspace un...

Localized corrosion in laser–arc hybrid welded high-nitrogen steel joints is strongly affected by microstructural heterogeneity. This study focused on the effect of welding speed on dendritic connectivity and the corre...

Abstract Background Euphorbia milii is a flowering ornamental plant that plays an important role in folk medicine. It has a variety of therapeutic effects due to its high content of many active compounds. This research p...

Nonlinear wave dynamics play an essential role in understanding energy localization, pulse transmission, and stability events in a variety of physical systems. Inspired by its importance, we study a fourth-order nonlinea...

IntroductionStudent engagement is a pivotal element in educational psychology, significantly impacting learning outcomes and academic achievement. Traditional methods for analyzing student engagement often rely on static...

This study investigates the failure and energy dissipation patterns of tuff under impact loads with varying occurrence conditions in Dahongshan Copper Mine through Split Hopkinson pressure bar (SHPB) tests, digital image...

SiC reinforced aluminum matrix composites (AMCs) are widely employed in various fields, and great importance has been attached to SiC/Al interface. Here, SiC/2009Al AMCs are fabricated for further research into SiC/Al in...

Increased focus on secure communications has created a growing interest in national and regional satellite systems. An elliptic medium earth orbit satellite system for Nordic/Arctic areas is proposed and investigated. Th...

High accuracy positioning has become a key capability for fifth generation (5G) mobile networks and their future generations; however, the achievable performance is still severely limited by network time synchronization,...

Abstract Advances in AI have transformed the traditional Internet of Things (IoT) into smarter, more versatile next-generation devices. Enhanced connectivity among sensors, actuators, and appliances boosts data availabil...

This study investigates the effect of discharge voltage on fracture distribution and fragmentation extent in multi-hole pulsed discharge rock fragmentation. Comparative experiments were conducted on red sandstone specime...

Abstract Background Protein-protein interaction (PPI) network-based protein function prediction algorithms, which use the guilt-by-association principle, are widely applied in medical and human domains, but they are comp...

Coronal mass ejections (CMEs) are eruptions originating from the solar corona, usually carrying a large amount of fast-flowing plasma into interplanetary space, accompanied by an enhanced magnetic field. CMEs can form sh...

Smilax glabra, a perennial vine with high pharmaceutical value, exhibits seed dormancy under natural conditions that severely restricts artificial propagation and industrial-scale cultivation. This study aims to systemat...

Sea ice fracture is a time-dependent process in which viscous relaxation delays the onset of cracking in the short term, but accumulated deformation and energy dissipation over long loading times can still lead to fractu...

Abstract This study investigates phase-dependent associations between Cross-Equatorial Northerly Surges (CENS) and Madden-Julian Oscillation (MJO) precipitation and circulation patterns using 84 years (1940–2023). Appr...

In this paper, a near-field integrated sensing and communication (ISAC) using a multi-waveguide pinching antenna system (PASS) is proposed, where discrete radiating particles are flexibly clamped along multiple dielectri...

Abstract Manipulating light at the nanoscale with minimal loss remains a central challenge for nanophotonic technologies that can be tackled by using the direction-dependent polariton modes supported by anisotropic mater...
