On ice but not broken: Norwegian–Russian relations in polar science since 24 February 2022 [PDF]
Western countries responded to the full-scale Russian attack on Ukraine on 24 February 2022 by imposing strong sanctions to isolate Russia. Norway has adhered to this policy, with exceptions for cooperation on border control, search and rescue, and ...

Review of The expeditions of the first International Polar Year 1882–83, by William Barr [PDF]
, 2009 It is probably safe to assume that no readers of Polar Research are unaware that we have just come through a fourth International Polar Year (IPY). All science is, or should be, based on the previous achievements of others, and thus the experiences and ...

Polar bear depredation of a thick-billed murre fledgling in open water at Prince Leopold Island, Nunavut [PDF]
, 2022 Sea-ice distribution and duration are declining across the circumpolar range of the polar bear (Ursus maritimus), resulting in a reduced access to ice-obligate seals, its primary prey.

Canadian Journal of Mathematics, 2003 AbstractFor complex projective manifolds we introduce polar homology groups, which are holomorphic analogues of the homology groups in topology. The polar k-chains are subvarieties of complex dimension k with meromorphic forms on them, while the boundary operator is defined by taking the polar divisor and the Poincaré residue on it. One can also define

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Polar bear hunt strategies evaluated by a Leslie matrix population model [PDF]
, 2010 An APL program for a Leslie matrix population projection is developed and applied to analysis of a Canadian polar bear population. Hunting specified with respect to sex ratio within a total quota may be included in the projections.

2010 IEEE International Symposium on Information Theory, 2010 The notion of source polarization is introduced and investigated. This complements the earlier work on channel polarization. An application to Slepian-Wolf coding is also considered. The paper is restricted to the case of binary alphabets. Extension of results to non-binary alphabets is discussed briefly.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...
