Rock Glaciers in Alaska [PDF]

The Journal of Geology, 1910
It is a generally admitted fact among observers of present-day geologic processes in high latitudes, but one upon which too little emphasis has been placed, that processes of weathering and removal of rock waste in sub-arctic regions are different from the controlling processes of degradation in more temperate regions.

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 ...

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.

Unchanged surface morphology in debris-covered glaciers and rock glaciers in Tröllaskagi peninsula (northern Iceland)

, 2019
This paper analyses changes in the surface morphology of rock and debris-covered glaciers in the Hóladalsjökull and Fremri-Grjótárdalur cirques near Hólar village in the Tröllaskagi peninsula (northern Iceland) (65°43′55″N; 19°06′49″W, 160 m), to ...

Recent Advances in Prussian Blue Analogs as Capacitive Deionization Electrode Materials: Fundamentals, Structure–Performance Relationships, and Design Strategies

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review systematically examines the fundamental ion‐storage mechanisms, the structural chemistry, and redox behavior of Prussian blue analogs as Faradaic electrodes in capacitive deionization, their intrinsic limitations and engineering optimization strategies, and the critical materials‐to‐device considerations required to advance PBA‐based CDI ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

The formation of valley-wall rock glaciers

, 2012
In recent years, the study of rock glaciers has increased remarkably. Substantive progress has been made, particularly in understanding the formation of rock glaciers that have developed adjacent to existing or former valley or cirque glaciers ...

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.
