Bayesian Sea Ice Detection With the ERS Scatterometer and Sea Ice Backscatter Model at C-Band [PDF]
, 2018 This paper describes the adaptation of a Bayesian sea ice detection algorithm for the scatterometer on-board the European Remote Sensing (ERS) satellites (ERS-1 and ERS-2).

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer
FEBS Letters, EarlyView.Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Global Change Biology, 2018 The Southern Ocean is currently experiencing major environmental changes, including in sea‐ice cover. Such changes strongly influence ecosystem structure and functioning and affect the survival and reproduction of predators such as seabirds.

Impact of melt ponds on Arctic sea ice simulations from 1990 to 2007 [PDF]
, 2012 The extent and thickness of the Arctic sea ice cover has decreased dramatically in the past few decades with minima in sea ice extent in September 2007 and 2011 and climate models did not predict this decline.

On sea ice concentration anomaly coherence in the southern Beaufort Sea
Geophysical Research Letters, 2005 The circumpolar flaw lead polynya system is a region of enhanced biological productivity and for significant portions of the annual cycle, dominates the exchange of energy and mass across the ocean‐sea ice‐atmosphere (OSA) interface. We investigate the nature of sea ice concentration (SIC) anomalies for spatial and temporal statistical persistence ...

Super Resolution of Arctic Sea Ice Concentration
, 2021 Arctic sea ice concentration is often coarsely observed and numerically computed despite its importance for polar climate system. In this work we present three machine-learning methods to recover the original high-resolution images from the coarse-grained low-resolution counterparts.

Molecular Oncology, EarlyView.This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Sea-ice indicators of polar bear habitat [PDF]
The Cryosphere, 2016 Nineteen subpopulations of polar bears (Ursus maritimus) are found throughout the circumpolar Arctic, and in all regions they depend on sea ice as a platform for traveling, hunting, and breeding.

Geophysical Research Letters, 2018 Sea ice kilometer‐scale characteristics are not explicitly represented in weather and climate model systems. However, due to the large differences of the surface temperature between sea ice and ocean, sea ice‐free areas (leads, polynyas, etc.) can have a

Study of the impact of ice formation in leads upon the sea ice pack mass balance using a new frazil and grease ice parameterisation [PDF]
, 2015 Leads are cracks in sea ice that often form due to deformation. During winter months leads expose the ocean to the cold atmosphere resulting in supercooling and the formation of frazil ice crystals within the mixed layer.
