Spatiotemporal variations in the impacts of small-to medium-scale mines agglomeration scale on landscape pattern and ecological risk in the watershed in a semi-arid ecologically fragile area

Ecological Indicators
Mining is one of the most pervasive of the various anthropogenic disturbances to landscape ecology. Currently, more attention is paid to the landscape ecological impacts caused by large-scale opencast mining, while small- to medium-scale mines (SMMs) are

Seismic metamaterial surface for broadband Rayleigh waves attenuation

Materials & Design, 2023
Elastic metamaterials (EMMs) have been widely studied owing to their advantages in controlling the propagation of elastic waves. In the past decade, considerable efforts have been made to attenuate Rayleigh waves using EMMs.

Modeling Magnetic Anisotropy of Single Chain Magnets in $|d/J| \geq 1$ Regime

, 2017
Single molecule magnets (SMMs) with single-ion anisotropies $\mathbf d$, comparable to exchange interactions J, between spins have recently been synthesized. In this paper, we provide theoretical insights into the magnetism of such systems. We study spin

Social media marketing strategy: definition, conceptualization, taxonomy, validation, and future agenda

Journal of the Academy of Marketing Science, 2020
Although social media use is gaining increasing importance as a component of firms’ portfolio of strategies, scant research has systematically consolidated and extended knowledge on social media marketing strategies (SMMSs). To fill this research gap, we

Spin-parity dependent tunneling of magnetization in single-molecule magnets

, 2001
Single-molecule magnets facilitate the study of quantum tunneling of magnetization at the mesoscopic level. The spin-parity effect is among the fundamental predictions that have yet to be clearly observed.

Two‐Way Shape Memory Alloy and Polymer Composite Hybrid Smart Actuator With High Speed, Accuracy, and Reversible Deformation

Advanced Functional Materials, EarlyView.
Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can
