Muon tomography for melting glaciers monitoring [PDF]

This thesis presents the development of an innovative detector for muography, aimed at monitoring glacier melting. The process of glacier melting is not completely understood and is considered a crucial parameter in view of the global warming. Muography is a widely used technique, that takes advantages of the muon flux reaching Earth surface, employed ...

Fixation Induces Mislocalization of Thin Filament Components in Caenorhabditis elegans Striated Muscle

Cytoskeleton, EarlyView.
ABSTRACT The simple nematode Caenorhabditis elegans has long served as a powerful genetic model system for studying muscle structure and function, with sarcomeres of the striated body wall muscle (BWM) that are considered largely homologous to those in vertebrates.

An Investigation Into the Yields of 3,4‐Methylenedioxyphenyl‐2‐propanone (MDP2P) From Glycidate Pre‐Precursors

Drug Testing and Analysis, EarlyView.
Hydrolysis of the glycidate pre‐precursors MMDMG and EMDMG was evaluated for MDP2P production. Acid hydrolysis of MMDMG (HCl, 100°C, 18 h) yielded the highest MDP2P recovery (79%), whereas base hydrolysis produced only slightly lower yields (73%), demonstrating both pathways are effective routes to this key MDMA precursor.

Updating Norway’s glacial lake extents in 2023–2024 using Sentinel-1 & Sentinel-2 data and machine learning

Journal of Glaciology
Glacial lakes are increasing in number and size worldwide, posing growing risks for outburst floods. Norway’s last glacial lake inventory used semi-automatic mapping on Sentinel-2 imagery from 2018–19.

Biotic Acceleration of Glacier Melting in Yala Glacier 9 Langtang Region, Nepal Himalaya

, 2020
In some Himalayan glaciers, the microbial production on the glacier surface is so large during the monsoon season that the surface of the ablation area is covered with a dark coloured mud-like material which mainly consists of algae and bacteria.

Spatio‐temporal dynamics of ringed seal density and habitat use in the Arctic's Last Ice Area

Ecography, EarlyView.
The Arctic is warming at approximately four times the global rate, driving widespread decline in sea ice extent, thickness, and seasonal duration. The ecological consequences of these rapid changes remain poorly understood within the Last Ice Area, a region that includes northern Ellesmere Island and the northwest of Greenland, projected to retain ...

Spatially heterogenous range dynamics since the Last Glacial Maximum underpin the modern bimodal latitudinal diversity gradient in planktonic foraminifera

Ecography, EarlyView.
The modern latitudinal diversity gradient (LDG) of planktonic foraminifera is bimodal, with a distinct depression near the equator surrounded by mid‐latitude diversity peaks. This pattern emerged after the Last Glacial Maximum (LGM; 19–23 ka), but it remains unclear how species' spatial dynamics contributed to its formation.

Spatial variation and predictors of plant species' intrinsic climate sensitivity across the conterminous United States

Ecography, EarlyView.
Understanding how species' sensitivity to climate varies spatially across their ranges and elucidating the important causes is essential for identifying ecologically meaningful geographic units and conservation actions for biodiversity. In this study, we estimated climatic occurrence niches of vascular plants to explore the spatial variation in species'

High-Temporal-Resolution Three-Dimensional Glacier Velocity Time Series and Their Implications for Glacier Dynamic Processes in Mt. Tomur, Tian Shan

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
High-temporal-resolution three-dimensional (3-D) glacier velocity measurements are essential for unraveling complex ice dynamics, enabling precise monitoring of climate-driven glacier response.
