Elevation-Dependent Glacier Albedo Modelling Using Machine Learning and a Multi-Algorithm Satellite Approach in Svalbard

Remote Sensing
Glacier surface albedo controls solar energy absorption and Arctic mass balance, yet comprehensive modelling approaches remain limited. This study develops and validates multiple modelling frameworks for glacier albedo prediction using automatic weather ...

True Closed‐Loop Recyclable Hydrogels Enabled by Imine Boronic Ester Crosslinking

Advanced Materials, EarlyView.
Subtle molecular differences in imine boronic ester crosslinkers profoundly influence hydrogel properties. 2‐formylphenylboronic acid crosslinkers form previously undisclosed 3‐amino‐benzoxaborole heterocycles, enhancing elasticity despite lower crosslinking density compared to their 4‐formylphenylboronic acid counterparts.

Modeling Ablation on Place Glacier, British Columbia, from Glacier and Off-glacier Data Sets [PDF]

Arctic, Antarctic, and Alpine Research, 2009
Abstract The results of two simulations of hourly ablation, from late July to September 2002, at a site on the Place Glacier are described. First, ablation is modeled from a data set collected at the glacier site; second, from a data set collected off-glacier at a site below the glacier tongue.

Covalent Attachment of Quaternary Ammonium Group to Geopolymer Surface With Silane Coupling Agent to Enable Simultaneous Adsorption of Cations and Anions

Advanced Materials Interfaces, EarlyView.
Modification of geopolymer surface with a silane coupling agent containing quaternary ammonium group enables the development of dual‐functioning ion exchanger for both cations and anions. In the present study, the performance of this material was demonstrated for the uptake of ammonium and nitrate from water.

Advance and thickening of the tidewater outlet glacier Eqalorutsit Kangilliit Sermiat surrounded by the thinning southern Greenland ice sheet

Journal of Glaciology
Although most Greenland glaciers have undergone thinning and frontal retreat in recent decades, the tidewater glacier Eqalorutsit Kangilliit Sermiat in South Greenland departs from this regional pattern.

Modelling Glaciers in the HARMONIE-AROME NWP model [PDF]

Advances in Science and Research, 2017
Abstract. HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multi-purpose SURFEX surface model. It is developed for high resolution (1–3 km) weather forecasting and applied in a number of regions in Europe and the Mediterranean. A version of HARMONIE-AROME is also under development for regional climate modelling. Here we

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

Advanced Science, EarlyView.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Initiation of a major calving event on the Bowdoin Glacier captured by UAV photogrammetry [PDF]

The Cryosphere, 2017
In this paper, we analyse the calving activity of the Bowdoin Glacier, north-western Greenland, in 2015 by combining satellite images, UAV (unmanned aerial vehicle) photogrammetry and ice flow modelling.

A Model for Sedimentation by Tidewater Glaciers [PDF]

Annals of Glaciology, 1981
Sampling of sediment from the fjord floor in front of tidewater glaciers in Glacier Bay, Alaska, has provided information about processes in this restricted glacimarine (Dreimanis 1979) setting. Sediment sampling, in conjunction with oceanographic and glacial dynamics data, has also enabled the discrimination of sediment types and their facies ...

A Disaggregation Strategy for Nanopesticide Fabrication: Investigating the Impact of Nanosizing on Pesticide Biointeractions

Advanced Science, EarlyView.
To explore the impact of nanosizing on pesticide biointeractions, a 7‐nm (average) emamectin benzoate nanopesticide without nanocarriers or surfactants is fabricated via HOAc‐mediated disaggregation. Nanosizing enhances bioactivity against Megalurothrips usitatus and Meloidogyne enterolobii and improves plant penetration.
