The dependence on applied shear of the morphological and rheological properties of diffusive binary systems after a quench from the disordered state into the coexistence region is investigated. In particular the behavior of the late-time transversal size of domains L_{y} and of the maximum of excess viscosity (Deltaeta)_{M} is considered. Numerical results show the existence of two regimes corr...

The linear discrepancy of a poset P is the least k such that there is a linear extension L of P such that if x and y are incomparable, then |hL(x)− hL(y)| ≤ k. Whereas the weak discrepancy is the least k such that there is a weak extension W of P such that if x and y are incomparable, then |hW (x)− hW (y)| ≤ k. This paper resolves a question of Tanenbaum, Trenk, and Fishburn on characterizing w...

If Gamma-Ray Bursts (GRBs) are cosmologically distributed standard candles and are associated with the luminous galaxies, then the observed angular distribution of all GRBs is altered due to weak gravitational lensing of bursts by density inhomogeneities. The amplitude of the effect is generally small. For example, if the current catalogs extend to zmax ∼ 1 and we live in a flat Ω = 1 Universe,...

Theories of gravity that obey the Weak Equivalence Principle have same Parametrised Post-Newtonian parameter $\gamma$ for all particles at energies. The large Shapiro time delays extragalactic sources allow us to put tight constraints on differences in between photons different frequencies from spectral lag data, since a non-zero $\Delta \gamma$ would result frequency-dependent arrival time. ma...

In weak-light environments, images suffer from low contrast and the loss of details. Traditional image enhancement models are usually failure to avoid issue overenhancement. this paper, a simple novel correction method is proposed based on an adaptive local gamma transformation color compensation, which inspired by illumination reflection model. Our converts source into YUV space, <math xmlns="...

Most X-ray afterglows of gamma-ray bursts (GRBs) observed by the Swift satellite have a shallow decay phase ∝ t in the first thousands of seconds. We discuss that the shallow decay requires an unreasonably high gamma-ray efficiency, & 75–90%, within current models, which is difficult to be produced by internal shocks. Such a crisis may be avoided if a weak relativistic explosion occurs ∼ 10–10 ...

It is unclear whether the two hippocampal lobes convey similar or different activities and how they cooperate. Spatial discrimination of electric fields in anesthetized rats allowed us to compare the pathway-specific field potentials corresponding to the gamma-paced CA3 output (CA1 Schaffer potentials) and CA3 somatic inhibition within and between sides. Bilateral excitatory Schaffer gamma wave...
