The dynamic constitutive relation of redeposited loess in Gannan region is investigated based on the dynamic triaxial tests. The model parameters are obtained, and the behaviors of dynamic shear modulus ratio and damping...

Abstract Current research on the dynamics and vibrations of geared rotor systems primarily focuses on deterministic models. However, uncertainties inevitably exist in the gear system, which cause uncertainties in system ...

The shear modulus and damping ratio of EPS composite soil, as a kind of artificial filling material, are the key parameters to analyze the dynamic stability of embankment. 15 cyclic torsional tests are conducted on the h...

To investigate the dynamic mechanical behavior and fragmentation characteristics of layered rock under the combined effects of chemical corrosion and impact loading, split Hopkinson pressure bar (SHPB) tests were perform...

If a metalens integrates the circular polarization (CP) conversion function, the focusing lens together with circular-polarizing lens (CPL) in traditional cameras may be replaced by a metalens. However, in terahertz (THz...

Estuaries function as sinks for microplastics due to their proximity to urban areas and pollution sources. Because of the great availability of plastic debris in these areas, these pollutants can be accumulated in biota ...

This study examines the second-order Kuramoto model within a specific small invariant subspace. We explore how the damping parameter influences the emergence of synchronized states and the weak chimera state in this mode...

As the core entities of China's modern agricultural operation system, green entrepreneurial behaviors of family farms are directly related to the implementation of ecological sustainability. Based on empirical data from ...

By means of time-resolved photoluminescence (TR-PL) spectroscopy, we present a detailed investigation of the carrier relaxation dynamics in a CsPbBr3 bulk sample and microcrystal ensemble at cryogenic temperature on a pi...

This study presents the dynamical analysis and soliton solutions of the Chaffee–Infante equation, an important nonlinear evolution model. The Chaffee Infante equation, widely employed as a reaction–diffusion model, i...

Abstract A decrease in the weight of aerospace vehicles, large ships, weapons, and high-speed trains will increase the demand for wide-width magnesium alloy plates and their composite parts to replace steel and plastic. ...

In recent years, the resilience of road traffic during abnormal events has drawn considerable attention. Intelligent navigation systems, which proactively guide drivers along optimal routes in such situations, are viewed...

We report experimental results of the speed-density relation emerging in pedestrian dynamics when individuals keep a prescribed safety distance among them. To this end, we characterize the movement of a group of people 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...

The escalating prevalence of overweight and obesity among young and middle-aged adults constitutes a significant public health challenge. While modifying dietary behavior is accepted as a critical component of weight man...

A model for studying the mechanical internal stresses into dielectric materials is developed in the present work. The model takes into account the formalism of inclusions in continuous media. The dielectric material is a...

Fluorinated ether-based electrolytes represent a promising avenue for improving lithium-ion battery performance and safety, yet the molecular mechanisms governing ion transport in these systems remain insufficiently unde...

In this paper, we present the development of a rigid-flexible multibody model which, coupled with an existing aerodynamic model, is used to numerically simulate the non-linear aeroelastic behavior of large horizontal-axi...

Introduction. Metaheuristic algorithms are effective for solving complex power system optimization problems characterized by nonlinearity, multimodality, and high dimensionality. Nature-inspired strategies based on adapt...

Understanding the strain-damage-energy dissipation mechanisms and evolution characteristics of deep coal and rock under impact loading is of great significance for the prevention and control of rockbursts. In this study,...

In order to study the earthquake seismic behaviors of ecological bags-reinforced wall, the large-scale shaking table model tests are performed. It is shown that the frequency decreases and the damping ratio increases wit...

Dynamic pricing is an important strategy in the highly competitive e-commerce industry, including on global platforms like Shopee. This strategy enables real-time adjustment of product prices based on changes in market d...

Abstract Background AIDS is a global public health issue that requires continuous monitoring and response. Although antiretroviral therapy has decreased the death rate among people living with HIV, several physical and m...
