Decadal Changes of the Reflected Solar Radiation and the Earth Energy Imbalance
Remote Sensing, 2019 Decadal changes of the Reflected Solar Radiation (RSR) as measured by CERES from 2000 to 2018 are analysed. For both polar regions, changes of the clear-sky RSR correlate well with changes of the Sea Ice Extent. In the Arctic, sea ice is clearly melting,

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer
Molecular Oncology, EarlyView.Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Inequalities for the polar derivative of a polynomial
Journal of Approximation Theory, 1988 Let \(D_{\alpha}P(z)\) denote the polar differentiation of the polynomial \(P(z)\) of degree \(n\) with respect to the point \(\alpha\), i.e. \(D_{\alpha}P(z)=nP(z)+(\alpha -z)P'(z)\). In this paper several inequalities of Bernstein type for complex polynomials are generalized to the case of the polar differentiation.

Molecular Oncology, EarlyView.This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

Zygmund’s Type Inequality to the Polar Derivative of a Polynomial [PDF]
International Journal of Advanced Research in Mathematics, 2016 In this paper we improve a result recently proved by Irshad et al. [On the Inequalities Concerning to the Polar Derivative of a Polynomial with Restricted Zeroes, Thai Journal of Mathematics, 2014 (Article in Press)] and also extend Zygmund's inequality to the polar derivative of a polynomial.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer
Molecular Oncology, EarlyView.Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Polar bears observed climbing steep slopes to graze on scurvy grass in Svalbard
, 2017 It is well known that polar bears feed on vegetation. Here, I report novel observations of polar bears grazing on polar scurvy grass (Cochlearia groenlandica) at the foot of a large seabird colony on a cliff on Spitsbergen, Svalbard, in the summers of ...

On ice but not broken: Norwegian–Russian relations in polar science since 24 February 2022
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 ...
