On the stability of many-body localization in $d>1$

open access: yes, 2019
Recent work by De Roeck et al. [Phys. Rev. B 95, 155129 (2017)] has argued that many-body localization (MBL) is unstable in two and higher dimensions due to a thermalization avalanche triggered by rare regions of weak disorder. To examine these arguments,

Seasonal and spatial variability of morphodynamic of slopes within snow avalanche starting zones in the Tatra Mountains

open access: yesRevista de Geomorfologie, 2022
. The paper aims to examine morphodynamic of slopes within the snow avalanche starting zones in the Tatras. The analysis of mophodynamic is based on results of four years monitoring of slope surface changes at 8 study sites.

Hysteresis and hierarchies: dynamics of disorder-driven first-order phase transformations

open access: yes, 1992
We use the zero-temperature random-field Ising model to study hysteretic behavior at first-order phase transitions. Sweeping the external field through zero, the model exhibits hysteresis, the return-point memory effect, and avalanche fluctuations. There

Dynamics of a ferromagnetic domain wall: avalanches, depinning transition and the Barkhausen effect [PDF]

open access: yes, 1998
We study the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium. The avalanche-like motion of the domain walls between pinned configurations produces a noise known as the Barkhausen effect. We discuss

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Keyed Hash Function Using Hyper Chaotic System With Time-Varying Parameters Perturbation

open access: yesIEEE Access, 2019
Secure hash function plays an important role in cryptography. This paper constructs a hash algorithm using the hyperchaotic Lorenz system, which serves as a sponge function to absorb input message via multiple parameters time-varying perturbation. First,

Al0.52In0.48P avalanche photodiodes for soft X-ray spectroscopy [PDF]

open access: yes, 2016
The performance of Al0.52In0.48P avalanche photodiodes was assessed as soft X-ray detectors at room temperature. The effect of the avalanche gain improved the energy resolution and an energy resolution (FWHM) of 682 eV is reported for 5.9 keV X ...
