Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]

, 2008
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Heterogeneous changes in global glacial lakes under coupled climate warming and glacier thinning

Communications Earth & Environment
Global glacial lakes have expanded markedly in recent decades, accompanied by many catastrophic glacial lake outburst floods. However, our understanding of glacial lake evolution and connections with global warming and glacier thinning remains ...

Talin1 Adhesion Morphology and Colocalization With Tensin3 Are Largely Unaffected by Polyacrylamide Substrate Stiffness

Cytoskeleton, EarlyView.
ABSTRACT Cells sense the stiffness of their extracellular matrix (ECM) and adapt their behavior accordingly. We investigated how ECM stiffness affects the spatial organization of talin1, a key mechanosensitive focal adhesion protein. Using polyacrylamide (PA) hydrogels with tunable stiffnesses (0.2–188 kPa), we analyzed cell morphology, migration ...

Impact of ocean stratification on submarine melting of a major Greenland outlet glacier [PDF]

, 2011
Submarine melting is an important balance term for tidewater glaciers1,2 and recent observations point to a change in the submarine melt rate as a potential trigger for the widespread acceleration of outlet glaciers in Greenland3-5.

Evaluation of Different Detection and Identification Methods of Intact Tetrahydro‐Methyltestosterone Sulfate Metabolites in Doping Control

Drug Testing and Analysis, EarlyView.
The micro‐scale synthesis of the six out of eight possible tetrahydro‐methyltestosterone sulfate metabolites was performed, and the synthesized materials were used as analytical standards. The analysis of post‐administration sample extracts from methyltestosterone excretion studies against these standards provides further experimental proof for their ...

Galerkin Least-Squares Stabilization in Ice Sheet Modeling - Accuracy, Robustness, and Comparison to other Techniques

, 2017
We investigate the accuracy and robustness of one of the most common methods used in glaciology for the discretization of the $\mathfrak{p}$-Stokes equations: equal order finite elements with Galerkin Least-Squares (GLS) stabilization.

Heterozygous Med13l mice recapitulate a developmental growth delay and craniofacial anomalies seen in MED13L syndrome

Developmental Dynamics, EarlyView.
Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

Mass-balance reconstruction for Glacier No. 354, Tien Shan, from 2003 to 2014

Annals of Glaciology, 2016
This study presents a reconstruction of the seasonal mass balance of Glacier No. 354, located in the Akshiirak range, Kyrgyzstan, from 2003 to 2014. We use a distributed accumulation and temperature-index melt model driven by daily air temperature and ...

Capillary Zone Electrophoresis for the Analysis of Phenolic Preservatives in Plasma and Insulin Formulations Using Salting‐Out Assisted Liquid–Liquid Extraction

ELECTROPHORESIS, EarlyView.
A rapid and reliable SALLE–CZE–UV method was developed for the determination of phenolic preservatives in insulin formulations and human plasma. The approach provides efficient extraction, fast separation (< 6 min), and excellent sensitivity, precision, and recovery, meeting regulatory requirements for accurate quantification.

Glacier recession since the Little Ice Age: Implications for water storage in a Rocky Mountain landscape

Arctic, Antarctic, and Alpine Research, 2019
Glaciers have significant influence on hydrology, vegetation, and wildlife in mountainous regions, and are receding globally. To quantify the impacts of sustained glacier loss, we mapped a complete set of glacier areas from the Little Ice Age (LIA) using
