Network analysis of ballast-mediated species transfer reveals important introduction and dispersal patterns in the Arctic [PDF]

arXiv, 2020
Rapid climate change has wide-ranging implications for the Arctic region, including sea ice loss, increased geopolitical attention, and expanding economic activity, including a dramatic increase in shipping activity. As a result, the risk of harmful non-native marine species being introduced into this critical region will increase unless policy and ...

Arctic curves of the six-vertex model on generic domains: the Tangent Method [PDF]

J. Stat. Phys. 164 (2016) 1488, 2016
We revisit the problem of determining the Arctic curve in the six-vertex model with domain wall boundary conditions. We describe an alternative method, by which we recover the previously conjectured analytic expression in the square domain. We adapt the method to work for a large class of domains, and for other models exhibiting limit shape phenomena ...

Human colon organoid differentiation from induced pluripotent stem cells using an improved method

FEBS Letters, Volume 599, Issue 6, Page 912-924, March 2025.
We compared established protocols to differentiate induced pluripotent stem cells into colon organoids and found that activation of bone morphogenetic protein 2 signaling induced gene expression of colon‐specific markers. Adenovirus‐mediated transduction of the transcription factors HOXD13 or SATB2 further enhanced colonic gene expression, suggesting ...

Intra-Annual Variability of the Surface Ablation of the Aldegondabreen Glacier (Spitsbergen)

Лëд и снег, 2023
The intra-annual variability of the surface ice ablation on the 5.5 km2 Aldegondabreen glacier (Spitsbergen Island, Barentsburg area) is presented. The ice ablation was measured during five seasons (2018–2022) at the two stakes, installed in the lower ...

The [2Fe‐2S] cluster of mitochondrial outer membrane protein mitoNEET has an O2‐regulated nitric oxide access tunnel

FEBS Letters, Volume 599, Issue 7, Page 952-970, April 2025.
The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.

The Useless Arctic: Exploiting Nature in the Arctic in the 1870s

Nordlit, 2015
<p align="LEFT">What is the discursive genealogy of an ecological approach to the Arctic? Building on distinctions suggested by Francis Spufford and Gísli Pálsson, this article examines a specific juncture in the history of European–Arctic interaction – the reception of the Austro-Hungarian Arctic Expedition in 1874 – and traces the potential for

Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase

FEBS Letters, Volume 599, Issue 8, Page 1146-1158, April 2025.
Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

Comprehensive study of old ice ridges in the Arctic Ocean

Лëд и снег, 2020
In May 2015, a comprehensive study of an old ice ridge was carried out to the north of Bennett Island in the East-Siberian Sea with application of water thermal drilling, tachometric and sonar surveys, video survey by the underwater device and methods ...
