Stochastic Dynamic Analysis of Polar Sea Ice Variability

Journal of Physical Oceanography, 1980
Abstract The analysis of Arctic (1966–76) and Antarctic (1973–79) sea ice data is presented, and a dynamical model based on white noise atmospheric forcing, local stabilizing relaxation and lateral diffusion and advection is constructed to explain the observations. Longitudinal dependent forcing. feedback, lateral diffusion and advection parameters are

Frazil dynamics and precipitation in a water column with depth-dependent supercooling [PDF]

, 2005
When seawater becomes supercooled, collections of small ice crystals, known as frazil ice, form and grow. A model of frazil ice dynamics is presented that deals explicitly with the buoyant settling of frazil crystals onto an overlying surface.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Evidence for the stability of the West Antarctic Ice Sheet divide for 1.4 million years [PDF]

, 2016
Past fluctuations of the West Antarctic Ice Sheet (WAIS) are of fundamental interest because of the possibility of WAIS collapse in the future and a consequent rise in global sea level.

Delivery of DNA‐encoded vaccines and proteins in mice using cutaneous suction‐mediated transfection

FEBS Open Bio, EarlyView.
Cutaneous suction‐mediated transfection in mice for delivery of DNA‐encoded vaccines and proteins. A critical limitation of DNA vaccines and other therapeutics is transfection in vivo to produce the encoded antigens or therapeutic proteins. Cutaneous suction‐based methods have demonstrated effectiveness in many animal models and have been successfully ...

Late Quaternary ice-ocean interactions in central West Greenland [PDF]

, 2011
A greater knowledge of the interactions between the Greenland Ice Sheet and climate is critical to understanding the possible impacts of future global warming, including ice sheet contribution to global sea-level rise and perturbations to ocean ...

The Roles of Sea-Ice, Light and Sedimentation in Structuring Shallow Antarctic Benthic Communities.

PLoS ONE, 2017
On polar coasts, seasonal sea-ice duration strongly influences shallow marine environments by affecting environmental conditions, such as light, sedimentation, and physical disturbance.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

The last glaciation of Shetland : local ice cap or invasive ice sheet? [PDF]

, 2014
Issue ISBN: 978-82-92-39488-5 This work is supported by the Carnegie Trust for the Universities of ScotlandThe question of whether the Shetland Islands were covered by an ice cap or by an ice sheet during the last glacial cycle (40–10 ka) remains ...
