The value of photoinduced birefringence in the polymer film was also measured (Delta n similar to 10(-3)) under CW laser excitation at 532 nm. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 120: 3065-3070, 2011″
“This open-label, non-interventional, controlled surveillance study evaluated the cognitive outcome of patients administered levetiracetam (LEV) or carbamazepine (CBZ) monotherapy as primary treatment or as substitution for previous treatment.

Executive functions, verbal memory, and subjective ratings were assessed before and 6 months after initiation of LEV or CBZ monotherapy. Analyses included 498 patients: 370 received LEV (63% pretreated), and 128 CBZ (34% pretreated). Mostly because of the substitution condition, the seizure freedom rate was slightly higher with LEV as opposed to CBZ (78% 5-Fluoracil supplier vs 69%). Almost all cognitive measures improved with LEV but not with CBZ, and repeated-measures MANOVA did not indicate seizure control or pretreatment as decisive with respect NCT-501 price to cognitive change. With LEV, executive functions improved in 15% and deteriorated in 5% of patients; the opposite pattern was seen under CBZ (improvement with LEV OR = 2.3, deterioration with CBZ OR = 3.4). The findings suggest a mild but definitely superior cognitive outcome with LEV as opposed to CBZ

monotherapy. (C) 2010 Elsevier Inc. All rights reserved.”
“The effect of noise on the process of high-speed remagnetization of vortex state of a pentagonal array of five circular magnetic nanoparticles is studied by means of computer simulation of Landau-Lifshits model. The mean switching time (MST) and its standard deviation (SD) of the reversal between the counterclockwise and clockwise vorticities have been computed. It has been demonstrated that with the reversal by the pulse with sinusoidal shape, the optimal pulse duration exists, which minimizes both the MST and the SD. Besides, both MST and SD significantly depend on the

angle between the reversal beta-catenin pathway magnetic field and pentagon edge, and the optimal angle roughly equals 10 degrees. Also, it is demonstrated that the optimization of the angle, duration and the amplitude of the driving field leads to significant decrease in both MST and SD. In particular, for the considered parameters, the MST can be decreased from 60 ns to 2-3 ns. Such a chain of magnetic nanoparticles can effectively be used as an element of magnetoresistive memory, and at the temperature 300 K the stable operation of the element is observed up to rather small size of nanoparticles with the radius of 20 nm.

“Poly(methyl methacrylate) (PMMA) monolayers with different molecular weights at the air/water interface were investigated at three different temperatures. The monolayer characteristics of PMMA were studied in terms of surface pressure-area per molecule (pi-A) isotherm and isobaric relaxation experiments.
