Self organized criticality in an improved Olami-Feder-Christensen model

, 2010
An improved version of the Olami-Feder-Christensen model has been introduced to consider avalanche size differences. Our model well demonstrates the power-law behavior and finite size scaling of avalanche size distribution in any range of the adding ...

Photoluminescence Turn‐On Method to Determine the Kinetics of Thermally Activated Delayed Fluorescence Materials

Advanced Physics Research, EarlyView.
Thermally Activated Delayed Fluorescence (TADF) is widely exploited to achieve high‐efficiency OLEDs. TADF Emitters are normally investigated with transient photoluminescence (PL), which requires the PL to be detected over multiple orders of magnitude in time and intensity.

Sixteen-year follow-up of childhood avalanche survivors

European Journal of Psychotraumatology, 2016
Background: Every year a substantial number of children are affected by natural disasters worldwide. However, data are scarce on long-term psychological impact of natural disasters on children's health.

Multifunctional Metasurfaces for Bridging Terahertz Waves in Free Space and Waveguides

Advanced Physics Research, EarlyView.
A multifunctional terahertz metasurface capable of simultaneous orthogonal polarization conversion and phase modulation is integrated onto a dielectric slab waveguide, thereby enabling efficient free‐space‐to‐guided‐wave coupling. By implementing tailored phase gradients on the metasurface, we demonstrate the formation of a focused spot within the ...

Snow Level Characteristics and Impacts of a Spring Typhoon-Originating Atmospheric River in the Sierra Nevada, USA

Atmosphere, 2018
On 5–7 April 2018, a landfalling atmospheric river resulted in widespread heavy precipitation in the Sierra Nevada of California and Nevada. Observed snow levels during this event were among the highest snow levels recorded since observations began

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Towards a model of glide-snow avalanche occurrence using in-situ soil and snow measurements

Journal of Glaciology
Glide-snow avalanches release at the soil-snow interface and are currently difficult to predict. This is mostly due to a limited understanding of the release process and a lack of data, particularly of the snowpack and underlying soil conditions prior to

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Experimental Investigation of Plastic Deformations Before Granular Avalanche

, 2012
We present an experimental study of the deformation inside a granular material that is progressively tilted. We investigate the deformation before the avalanche with a spatially resolved Diffusive Wave Spectroscopy setup.

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...
