Blue shift of the heavy-hole peak of the photocurrent spectra has been observed, for the first time, in narrow GaAs/Alc4Ga.e6As asymmetric coupled quantum wells near the heavyhole resonance. With an external reverse bias of only 2.35 V, a maximum upward shift of the apparent peak position of 6.1 meV has been measured at 78 K. Sharp change of the inhomogeneous linewidth of the heavy-hole peak ha...

Nuclear magnetic resonance has emerged as a vital tool to explore the fundamental physics of Kondo lattice systems. Because nuclear spins experience two different hyperfine couplings to the itinerant conduction electrons and to the local f moments, the Knight shift can probe multiple types of spin correlations that are not accessible via other techniques. The Knight shift provides direct inform...

Common lore has it that naturalness of electroweak breaking in the SM requires new physics (NP) at Λ < ∼ 2− 3 TeV, hopefully within the reach of LHC. Moreover the Higgs should be light (m h < ∼ 219 GeV) to pass electroweak precision tests (EWPT). However one should be prepared for " unexpected " (although admittedly unpleasant) results at LHC, i.e. no NP and/or a heavy Higgs. We revisit recent ...

Mucosal immunoglobulin (Ig)A dominance has been proposed to be associated with preferential class switch recombination (CSR) to the IgA heavy chain constant region, Calpha. Here, we report that B cell activation in nasal-associated lymphoid tissue (NALT) upon stimulation with the hapten (4-hydroxy-3-nitrophenyl)acetyl (NP) coupled to chicken gamma globulin caused an anti-NP memory response domi...

A precise determination of the neutron skin Δr(np) of a heavy nucleus sets a basic constraint on the nuclear symmetry energy (Δr(np) is the difference of the neutron and proton rms radii of the nucleus). The parity radius experiment (PREX) may achieve it by electroweak parity-violating electron scattering (PVES) on (208)Pb. We investigate PVES in nuclear mean field approach to allow the accurat...

Neuropsychiatric (NP) involvement in systemic lupus erythematosus (SLE) is one of the most severe manifestations of the disease that has a heavy impact on patient's functioning, quality of life, and disease outcome. The prevalence is highly variable and the clinical phenotypes vary from common syndromes to rare NP entities. Its occurrence may be the result of a primary manifestation of SLE, sec...

The problem of the sample variance computation for epistemic inter-val-valued data is, in general, NP-hard. Therefore, known efficient algorithms for computing variance require strong restrictions on admissible intervals like the no-subset property or heavy limitations on the number of possible intersections between intervals. A new asymptotic algorithm for computing the upper bound of the samp...
