CMB Optical Depth Measurements: Past, Present, Future
, 2005
"... The polarization of the cosmic microwave background (CMB) is encoded with exactly the same cosmic information as the CMB’s temperature anistropy. However, polarization has the additional promise of accurately probing the reionization history of the universe and potentially constraining, or detecting ..."

DOI: 10.1016/j.cplett.2008.06.009 Timedependent photoionization of azulene: Optically induced anistropy on the femtosecond scale

"... We measure the photoionization crosssection of vibrationally excited levels in the S2 state of azulene by femtosecond pumpprobe spectroscopy. At the wavelengths studied (349265 nm in the pump) the transient signals exhibit two distinct and welldefined behaviours: (i) Shortterm (on the order of a ..."

We measure the photoionization crosssection of vibrationally excited levels in the S2 state of azulene by femtosecond pumpprobe spectroscopy. At the wavelengths studied (349265 nm in the pump) the transient signals exhibit two distinct and welldefined behaviours: (i) Shortterm (on the order of a picosecond) polarization dependent transients and (ii) longer (10 ps – 1 ns) timescale decays. This letter focuses on the short time transient. In contrast to an earlier study by Diau et al.(1) we unambiguously assign the fast initial decay signal to rotational dephasing of the initial alignment created by the hal00289272, version 1 20 Jun 2008 pump transition.
Signatures of short distance physics in the cosmic microwave background,” Phys
 Rev. D
"... We systematically investigate the effect of short distance physics on the spectrum of temperature anistropies in the Cosmic Microwave Background produced during inflation. We present a general argument–assuming only low energy locality–that the size of such effects are of order H 2 /M 2, where H is ..."

Dynamic Mechanical Property Anisotropy of ZA31 Alloy by Equal Channel Angular Pressing
"... Abstract: the microstuctures and orientations changing of hot extrusion AZ31 magnesium alloy were obtained by equal channel angular pressing (ECAP). After the ECAP samples annealed, the dynamic anistropy of AZ31 alloy in different impacting directions were given by dynamic compressing in HSPB system ..."

We present a numerical method which computes the motion of complex solid/liquid boundaries in crystal growth. The model we solve includes physical effects such as crystalline anisotropy, surface tension, molecular kinetics and undercooling. The method is based on two ideas. First, the equations of motion are recast as a single historydependent boundary integral equation on the solid/liquid boundary. A fast algorithm is used to solve the integral equation efficiently. Second, the boundary is moved by solving a "HamiltonJacobi "type equation (on a fixed domain) formulated by Osher and Sethian for a function in which the boundary is a particular level set. This equation is solved by finite difference schemes borrowed from the technology of hyperbolic conservation laws. The two ideas are combined by constructing a smooth extension of the normal velocity off the moving boundary, in a way suggested by the physics of the problem. Our numerical experiments show the evolution of complex cryst...

"... The magnetoresistance due to electronspin scattering in antiferromagnetic metals is obtained in the lowtemperature region to 6e order of J2 assuming that the sd interaction J is small, i.e, T N'PT:PJ. Compared with the results in the simple molecular field approximation, the magnetoresistan ..."

"... Magnetic anisotropy has been measured for the ferromagnetic La0.7Sr0.3CoO3 perovskite from an analysis of the highfield part of the magnetization vs. field curves, i.e., the magnetic saturation regime. These measurements give a magnetic anistropy one order of magnitude higher than that of reference ..."
