Superconductivity at T_c ~ 14 K in Single Crystalline FeTe0.61_{0.61}Se0.39_{0.39}

Single crystalline FeTe$_{0.61}$Se$_{0.39}$ with a sharp superconducting transition at $T_{\textrm{c}} \sim$ 14 K is synthesized via slow furnace cooling followed by low-temperature annealing. The effect of annealing on the chemical and superconducting inhomogeneities is carefully characterized. We also report resistivity, magnetization, and magneto-optical images of this crystal. Based on the Bean model, critical current density is estimated to exceed $1 \times 10^5$ A/cm$^2$ below 5 K under zero field. Weak fish-tail effect is identified at lower temperatures.Comment: 4 pages, 4 figure

A review of studies mapping (or cross walking) from non-preference based measures of health to generic preference-based measures

This paper presents a systematic review of current practice in mapping between nonpreference based measures and generic preference-based measures. It reviews the studies identified by a systematic search of the published literature and the grey literature. This review seeks to address the feasibility and overall validity of this approach, the circumstances when it should be considered and to bring together any lessons for future mapping studies

Pump- and Probe-polarization Analyses of Ultrafast Carrier Dynamics in Organic Superconductors

We investigated photo-excited carrier relaxation dynamics in the strongly correlated organic superconductors kappa-(BEDT-TTF)(2)Cu(NCS)(2) and kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br, using different polarizations of pump and probe pulses. Below the glasslike transition temperature (T (g)) anisotropic responses for probe polarization were observed in both compounds. Decomposing the data into anisotropic and isotropic components, we found the anisotropic component shows no pump polarization dependence, meaning that dissipative excitation process was dominant for the anisotropic carrier relaxation. This behavior indicates that the appearance of anisotropic responses can be associated with spatial symmetry breaking due to structural change of BEDT-TTF molecules

String Field Theory from IIB Matrix Model

We derive Schwinger-Dyson equations for the Wilson loops of a type IIB matrix model. Superstring coordinates are introduced through the construction of the loop space. We show that the continuum limit of the loop equation reproduces the light-cone superstring field theory of type IIB superstring in the large-N limit. We find that the interacting string theory can be obtained in the double scaling limit as it is expected.Comment: 21 pages, Latex, 1 figur

The effect of adrenaline on cardiac AMP-activated protein kinase.

In freshly isolated adult rat cardiac myocytes, adrenaline decreased AMPK activity and Thrl72 phosphorylation in AMPK a-subunits. This was associated with a decrease in AMPK-driven phosphorylation of acetyl-CoA carboxylase. The effect of adrenaline on AMPK was rapid with a half-time of approximately 4 minutes. The inactivation of AMPK by adrenaline was not associated with detectable changes in the myocyte contents of ATP, ADP, AMP, creatine, and creatine phosphate. The effect of adrenaline on AMPK was preserved under conditions where AMPK was activated by palmitate or sorbitol, but it was markedly diminished when AMPK was activated by 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), oligomycin, or phenformin. The effect of adrenaline was partially blocked by propranolol (0-adrenergic antagonist) or phentolamine (ai-adrenergic antagonist) while it was essentially abolished when both blockers were present, suggesting involvement of both p and ai adrenergic receptors. Isoproterenol (P-adrenergic agonist) and phenylephrine (ai-adrenergic agonist) could also decrease AMPK activity and Thrl72 phosphorylation. Adrenaline did not increase phosphorylation of Ser485/491 in the AMPK a-subunit, but incubation of a catalytically inactive AMPK complex (aipiyl) with a cell lysate from adrenaline-treated myocytes increased phosphorylation of the AMPK pi subunit. The effect of adrenaline was not mimicked by conditions that activated cAMP-pathways and was not blocked by an inhibitor of calcium/calmodulin-dependent kinase II. However, a phorbol ester could mimic the effect of adrenaline on AMPK, suggesting the possible involvement of PKC isoforms
