Dynamical Instabilities of Ice X
Physical Review Letters, 2008 Water ice X is stable in the 120-400 GPa pressure range, as obtained from lattice dynamical calculations performed using the density-functional theory. Below 120 GPa, it is characterized by one unstable flat phonon band, which generates the disordered ice X structure.

Dynamic behaviour of rutford ice stream [PDF]
Annals of Glaciology, 1982 The grounding-line region of Rutford Ice Stream was surveyed from the ground during 1978–79 and 1979–80, and from the air in 1980–81. Maps of surface elevation and ice thickness of an area of 1 000 km2allow the grounding line to be delineated and show that the ice stream consists of several distinct fingers of thick ice trending parallel to the flow ...

AA-stacked bilayer square ice between graphene layers?
, 2015 Water confined between two layers with separation of a few Angstrom forms layered two- dimensional ice structure. Using large scale molecular dynamics simulations with the adoptable ReaxFF interatomic potential we found that flat monolayer ice with a ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Environmental drivers of under-ice phytoplankton bloom dynamics in the Arctic Ocean
Elementa: Science of the Anthropocene, 2020 The decline of sea-ice thickness, area, and volume due to the transition from multi-year to first-year sea ice has improved the under-ice light environment for pelagic Arctic ecosystems.

Orbital ice: an exact Coulomb phase on the diamond lattice
, 2011 We demonstrate the existence of orbital Coulomb phase as the exact ground state of p-orbital exchange Hamiltonian on the diamond lattice. The Coulomb phase is an emergent state characterized by algebraic dipolar correlations and a gauge structure ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Anisotropic Radial Basis Function Methods for Continental Size Ice Sheet Simulations
, 2017 In this paper we develop and implement anisotropic radial basis function methods for simulating the dynamics of ice sheets and glaciers. We test the methods on two problems: the well-known benchmark ISMIP-HOM B that corresponds to a glacier size ice and ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Weichselian phases and ice dynamics of the Scandinavian Ice Sheet in Northeast Germany
, 2017 This thesis presents new geochronological and geomorphological data concerning Weichselian ice dynamics of the Scandinavian Ice Sheet for the northeast German lowland area. The largest Weichselian ice extent in Brandenburg (Brandenburg phase) occurred in
