Polyamorphism of ice at low temperatures from constant-pressure simulations
, 2004 We report results of MD simulations of amorphous ice in the pressure range 0 - 22.5 kbar. The high-density amorphous ice (HDA) prepared by compression of Ih ice at T = 80 K is annealed to T = 170 K at intermediate pressures in order to generate relaxed ...

Sea Ice Dynamics Induced by External Stochastic Fluctuations [PDF]
, 2013 The influence of stochastic fluctuations in the atmosphere and in the ocean caused by different occasional phenomena (noises) on dynamic processes of sea ice growth with a mushy layer is studied.

Luminous Phenomena on Rupture of Sea-Ice [PDF]
Nature, 1881 IN my diary for January 20, 1881, occurs the following passage. I make no attempt to account for the phenomenon, but am certain it was not caused by any reflection of the lights on board the vessel:—

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

The statistical relation/coherence between ice-regimes of Lake Raduńskie Górne and Lake Ostrzyckie
Limnological Review, 2018 This article is an attempt to analyse and compare several selected parameters regarding ice phenomena using the correlation analysis of two lakes, which are benchmark lakes located in the central part of the Kashubian Lakeland. These lakes are: Raduńskie

A powerful computational crystallography method to study ice polymorphism
, 2011 Classical Molecular Dynamics (MD) simulations are employed as a tool to investigate structural properties of ice crystals under several temperature and pressure conditions. All ice crystal phases are analyzed by means of a computational protocol based on

Onsager's Wien Effect on a Lattice [PDF]
, 2013 The Second Wien Effect describes the non-linear, non-equilibrium response of a weak electrolyte in moderate to high electric fields. Onsager's 1934 electrodiffusion theory along with various extensions has been invoked for systems and phenomena as ...

Interference Phenomena in Deformed Single Crystals of Ice [PDF]
Journal of Glaciology, 1971 Abstract When rectangular single crystals of ice were subjected to uniaxial compression parallel to their Long axes and viewed between crossed polarizers, interference fringes were often observed. Some of these interference bands were associated with grain boundaries formed as a result of “kinking”.

Insights into a long life without cancer: The case of the bowhead whale
Molecular Oncology, EarlyView.Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
FEBS Open Bio, EarlyView.The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.
