the behcet disease (bd) is a systemic inflammatory disease of unknown etiology. evidences suggest that at least some of the clinical aspect of the bd may be due to autoimmune responses, these includes elevated levels of immunoglobulins (igs) and immune complexes. to clarify the molecular basis of the changes in the level of different classes of igs in bd, we have detected the amount of igg, igm...

Building on the recent breakthrough by Ogihara, we resolve a conjecture made by Hartmanis in 1978 regarding the (non) existence of sparse sets complete for P under logspace many-one reductions. We show that if there exists a sparse hard set for P under logspace many-one reductions, then P = LOGSPACE. We further prove that if P has a sparse hard set under many-one reductions computable in NC1, t...

We report on our ongoing investigation of the deconfining phase transition in SU(4) and SU(6) gauge theories. We calculate the critical couplings while taking care to avoid the influence of a nearby bulk phase transition. We determine the latent heat of the phase transition and investigate the order and the strength of the transition at large Nc. We also report on our determination of the criti...

We present an NC approximation algorithm for the weighted matching problem in graphs with an approximation ratio of (1 − ). This improves the previously best approximation ratio of ( 1 2 − ) of an NC algorithm for this problem.

The potencies of atracurium, Org NC 45 and pancuronium were determined using cumulative dose-response curves. The effective doses producing 95% twitch depression were 279 microgram kg-1, 56 microgram kg-1 and 64 microgram kg-1 respectively, the relative potency being 1:5.0:4.3. The calculated log-probit dose-response curves showed the steepest slope for pancuronium, although the slopes did not ...

Organic-inorganic hybrid heterojunctions have potential as the basis for future photovoltaic devices. Herein, we report the results of investigations exploring the possibility of using pentacene and tetracene as photoelectron donors in conjunction with PbS nanocrystals (PbS-NCs). Photoinduced charge transfer was probed using external quantum efficiency measurements on acene:PbS-NC hybrid photov...

Beisert et al. have identified an integrable SU(2, 2) quantum spin chain which gives the one-loop anomalous dimensions of certain operators in large Nc QCD. We derive a set of nonlinear integral equations (NLIEs) for this model, and compute the scattering matrix of the various (in particular, magnon) excitations. 1 Department of Physics, Ewha Womans University, Seoul 120-750, South Korea 2 Phys...
