PROBABILISTIC ZONING OF ADJACENT CATCHMENTS BY PHYSICAL MODELING

open access: yesЛëд и снег, 2015
Now the probabilistic zoning of avalanche sites is being made either on the basis of the available field data, or using the mathematical and physical modeling of avalanche dynamics processes.

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

open access: yesCarbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

Dynamic Calibration of DEM Simulations Using Rotating Drum Experiments Using the Mean Absolute Error

open access: yesChemie Ingenieur Technik, EarlyView.
Calibrating DEM simulations is challenging due to unknown microscopic parameters. Rotating drum experiments are combined with image‐based analysis and Latin Hypercube Sampling (LHS). An area‐based Mean Absolute Error (MAE) enables reliable identification of optimal parameter sets.

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

open access: yesEcography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Determinación de procesos y áreas de riesgos en los Andes centrales de Chile mediterráneo: Casos de estudio

open access: yesPirineos: Revista de Ecología de Montaña, 1994
[es] Durante la realización del proyecto de Cartografía de Riesgos de Montaña en los Andes Centrales de Chile (Proyecto FONDECYT nº 482- 91) se cartografiaron los riesgos naturales en la cuenca del Aconcagua, altos Andes (2.500 a 4.000 m). Varios riesgos

Ag‐Induced Phase and Defect Engineering of Co‐Evaporated Sb2Se3 Thin Films for Enhanced Photovoltaic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The sequential formation of Ag2Se and AgSbSe2 phases at the Sb2Se3/Mo interface upon Ag incorporation in co‐evaporated Sb2Se3 solar cells promotes grain growth and defect passivation. These newly formed intermediate phases enhance crystallinity and suppress recombination, leading to significant improvements in open‐circuit voltage, fill factor, and ...

Dynamic models for impact-initiated stress waves through snow columns

open access: yesJournal of Glaciology
The objective of this research is to model snow's response to dynamic, impact loading. Two constitutive relationships are considered: elastic and Maxwell-viscoelastic.

Effect of Electromyography Findings of Traction‐Related Signal Loss on Prognosis During Neuromonitored Thyroidectomy

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Intraoperative neuromonitoring (IONM) is a reliable tool to detect electromyographic loss of signal (LOS). Here, we investigated the effect of electromyography features of traction‐related LOS on prognosis. Methods Thyroidectomy patients with a traction‐related LOS were included.

Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.
