Characteristics of off-waist incident anomalous vortex beams in highly nonlocal media [PDF]

open access: yesResults in Physics, 2017
In this paper, we focus on the effect of the off-waist incident condition on the propagation characteristics of anomalous vortex beams (AVBs) in nonlocal media. An expression is derived mathematically in order to describe the propagation dynamics of AVBs

Auxetics and Other Systems of Anomalous Characteristics [PDF]

open access: yesphysica status solidi (b), 2019
The present volume on materials and models with negative Poisson's ratio (which are often referred to as “auxetics”) and other systems of anomalous characteristics is the thirteenth focus issue of physica status solidi (b) on this subject. The volume contains twenty papers grouped into three sections: macroscopic auxetic materials and models ...

2021年青海玛多MS7.4地震前大武台地电场优势方位角异常特征分析

open access: yesDizhen xuebao, 2023
为了深入了解2021年5月22日青海省玛多MS7.4地震前是否存在地震电信号,本文利用地电场优势方位角方法对大武地电场的原始资料进行了分析,获得了玛多地震前震中附近场地的岩体裂隙结构变化特征,并结合本次地震震中500 km范围内八个地电场台站的岩体裂隙结构变化和该台记录到的以往震例中大武台地电场优势方位角异常变化与中强地震之间的关系进行了综合分析。结果显示:大武台新旧两套地电场数据的地电场优势方位角在震前11个月出现了显著的同步偏转现象,其中大武旧台在震前两个月优势方位角再次出现大幅度上升 ...

Anomalous dispersion observed in signal arrivals at a deep-sea floor receiver [PDF]

open access: yesJASA Express Letters, 2021
An anomalous dispersion, e.g., when low frequencies arrive earlier whereas the high frequencies arrive later, was observed in the signal arrivals recorded by a single deep-sea bottom-mounted vector sensor.

Experimental study on the infrared precursor characteristics of gas-bearing coal failure under loading

open access: yesInternational Journal of Mining Science and Technology, 2021
The stress and gas pressure in deep coal seams are very high, and instability and failure rapidly and intensely occur. It is important to study the infrared precursor characteristics of gas-bearing coal instability and failure.

A vector field approach for identifying anomalous human mobility

open access: yesIET Intelligent Transport Systems, 2023
Although ordinary human mobility has been extensively studied, anomalous human mobility during emergencies or mass events is not sufficiently understood. The recently proposed vector field approach has shed light on human mobility studies.

Saturation of the anomalous Hall effect at high magnetic fields in altermagnetic RuO2

open access: yesAPL Materials, 2023
Observations of the anomalous Hall effect in RuO2 and MnTe have demonstrated unconventional time-reversal symmetry breaking in the electronic structure of a recently identified new class of compensated collinear magnets, dubbed altermagnets.
