Surge of the Bivachny Glacier in 2012–2015

Лëд и снег, 2015
The surge of the Bivachny Glacier that occurred in 2012–2015 is analyzed with the use of photographing performed from International Space Station in 2001–2015 together with data of the satellite monitoring of 1972–2000.

A nanoplatform that induces dual‐amino acid deprivation to reverse tumor immunosuppression and enhance metabolic immunotherapy

BMEMat, EarlyView.
ZIF‐8‐based nanoparticles co‐delivering CB‐839 (glutaminase inhibitor) and 1‐MT (IDO1 inhibitor), dual‐targeting glutamine/tryptophan metabolism to induce immunogenic cell death, activate STING, block kynurenine production, reverse immunosuppression, and enhance cancer immunotherapy to suppress primary/distant tumors.

Does Climate Risk Affect Employment Decisions? International Evidence

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the effect of climate risk on corporate employment decisions. Using a large sample from 41 countries, we find a positive association between climate risk and underinvestment in labor, notably manifesting as excessive employee layoffs.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Utilising seismic station internal GPS for tracking surging glacier sliding velocity

Journal of Glaciology
Glacier ice flux is a key indicator of mass balance; therefore, accurate monitoring of ice dynamics is essential. Satellite-based methods are widely used for glacier velocity measurements but are limited by satellite revisit frequency.

Glaciers as an Important Element of the World Glacier Monitoring Implemented in Svalbard

, 2017
Glaciers are not only contributors to the sea level rise but also important players in the circulation of pollutants. Over a billion people apply glacial waters for domestic purposes; hence, both the quality and quantity of this water should be monitored.

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

Chemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

An Adaptive Homogeneous Pixel-Offset Tracking Technique Integrated With SAR Change Detection: A Case Study of Glacier Displacement Monitoring at Namcha Barwa in the Himalayas

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Global warming has accelerated glacier and snowmelt, leading to hazards such as debris flows and glacial lake outburst floods. Accurate time-series monitoring of glacier deformation is essential for disaster early warning and glacier dynamics research ...

Human-caused climate change in United States national parks and solutions for the future [PDF]

, 2020
Human-caused climate change has exposed the US national park area to more severe increases in heat and aridity than the country as a whole and caused widespread impacts on ecosystems and resources.
