A protein that causes a cell's skeleton to bend, allowing it to twist the cell into different shapes, could be key to how cells divide according to scientists.
An interdisciplinary team of Cornell researchers has taken its breakthrough discovery – which melded the ability of soft organic materials to spontaneously self-organize with quantum materials to crea...
From a mountain high in Chile's Atacama Desert, astronomers at the U.S. National Science Foundation's Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in th...
A long-held hypothesis about the factors that govern species ranges largely holds true, but may be the result of a previously underappreciated ecological mechanism, new research shows.The prediction, ...
A microplate discovered off the west coast of Ecuador adds another piece to Earth’s tectonic puzzle, according to Rice University scientists.Researchers led by Rice geophysicist Richard Gordon discove...
The purpose of this paper is twofold. First we show that the dynamics ofa Sun-Jupiter-Comet system and under some simplifying assumptions has a semi-infiniteregion of instability. This is done by redu...
The Hodgkin and Huxley equations model action potentials in squid giant axons. Variants of these equations are used in most models for electrical activity of excitable membranes. Computational tools...
The saga of the Osedax “bone-eating” worms began 12 years ago, with the first discovery of these deep-sea creatures that feast on the bones of dead animals. TheOsedax story grew even st...
The N-enlarged Galilei Hopf algebra is constructed. Its twist deformations are considered and the corresponding twisted space-times are derived.
We present and discuss the theory and phenomenology of the leading twist theory of nuclear shadowing which is based on the combination of the generalization of Gribov-Glauber theory, QCD factorization...
Abstract: Much work has been done on the existence and uniqueness of broken Lefschetz fibrations such as those by Auroux et al., Gay and Kirby, Lekili, Akbulut and Karakurt, Baykur, and Williams, but ...
We present and discuss the theory and phenomenology of the leading twist theory of nuclear shadowing which is based on the combination of the generalization of Gribov-Glauber theory, QCD factorization...
Noncommutative oscillators are first-quantized through an abelian Drinfel’d twist deformation of a Hopf algebra and its action on a module. Several impor-tant and subtle issues making possible the qua...
A new twist on transmission electron microscopy (TEM) could enable the technique to unlock even more secrets on the nanoscale. Researchers in the US have produced a helical-shaped beam of electrons th...
We study the evolution of magnetic shear angle in a flare productive active region NOAA 10930. The magnetic shear angle is defined as the deviation in the orientation of the observed magnetic field ve...
