Genese des Nordseeraumes im Quartär

Fennia: International Journal of Geography, 1974
In spite of alterations due to transgressions, Pleistocene forms are still discernible in the North Sea area. In this study, explanation of their genesis is based on a reconstruction of the ice‑sheds of different dimen­sions and the dynamic elements of ...

Multi-decadal evolution of Crary Ice Rise region, West Antarctica, amid modern ice-stream deceleration

Journal of Glaciology
The ongoing deceleration of Whillans Ice Stream, West Antarctica, provides an opportunity to investigate the co-evolution of ice-shelf pinning points and ice-stream flux variability.

Groundwater dynamics beneath a marine ice sheet [PDF]

The Cryosphere
Sedimentary basins beneath many Antarctic ice streams host substantial volumes of groundwater, which can be exchanged with a “shallow” subglacial hydrological system of till and channelised water.

Identification of PKN2 and MOB4 as Coordinators of Collective Cell Migration

Advanced Science, EarlyView.
Through a genetic screen, PKN2 and MOB4 are identified as two proteins regulating the healing of an epithelial model wound. PKN2 promotes collective cell migration by maintaining the cohesion of cell monolayers from their lateral junctions, whereas MOB4 restrains collective cell migration and provides a lamellipodial cue for front‐rear polarity in ...

Enlargement of the active rift during glaciations [PDF]

, 2010
During the last glaciation, an ice sheet covered Iceland approximately 1000 m thick. A reconstruction of the ice flow lines shows that the ice sheet was partly drained through fast-flowing streams.

Local manifestations of cometary activity [PDF]

, 2019
Comets are made of volatile and refractory material and naturally experience various degrees of sublimation as they orbit around the Sun. This gas release, accompanied by dust, represents what is traditionally described as activity.

Construction of a Multitissue Cell Atlas Reveals Cell‐Type‐Specific Regulation of Molecular and Complex Phenotypes in Pigs

Advanced Science, EarlyView.
This research conducts an in‐depth investigation of cell‐type‐specific regulatory mechanisms underlying molecular and complex phenotypes through integrative analysis of multitissue single‐nucleus RNA sequencing, bulk RNA‐seq, and genome‐wide association study (GWAS) data in pigs.

Survival, growth, and yield of brown trout stocked as fingerlings in Hot Creek, California [PDF]

, 1998
Four groups of fin clipped brown trout (Salmo trutta) fingerlings were planted in Hot Creek over a six year period. Survival and growth were estimated by fall and/or spring mark-and-recapture surveys.

2‐line Ferrihydrite Enhance Microbial Synthesis of Plant Biostimulants in Composted Biosolid by Regulating Phyla Pseudomonadota and Actinomycetota

Advanced Science, EarlyView.
This study explores how iron and manganese oxides transform sewage sludge into plant biostimulants during composting. Non‐targeted identification reveals the main species of plant biostimulants. Metagenomic analysis reveals that 2‐line ferrihydrite specifically enriches microbial genes for biosynthesis, boosting plant‐growth promoters.

Data report for the Siple Coast (Antarctica) project [PDF]

This report presents data collected during three field seasons of glaciological studies in the Antarctica and describes the methods employed. The region investigated covers the mouths of Ice Streams B and C (the Siple Coast) and Crary Ice Rise on the ...
