The many-body localised (MBL) to thermal crossover observed in exact diagonalisation studies remains poorly understood as the accessible system sizes are too small be an asymptotic scaling regime. We develop a model of short 1D chains which MBL phase is destabilised by formation resonances. reproduces several properties numerically crossover, including apparent correlation length exponent $\nu=...

background lumbar plexus block (lpb) is one of the anesthetic options in the elderly patients undergoing hip surgeries. lpb could be safe because it targets somatic nerve in psoas region. effectiveness of lpb is attributed to the sufficient analgesia provided intraoperatively as well as postoperatively. adequate muscle relaxation and immobility during surgery refers to its acceptability. object...

Block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. In this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. The factor fphil is defined as the ratio of the number...

Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...

In this paper we introduce a sequential block iterative method and its simultaneous version with op-timal combination of weights (instead of convex combination) for solving convex feasibility problems.When the intersection of the given family of convex sets is nonempty, it is shown that any sequencegenerated by the given algorithms converges to a feasible point. Additionally for linear feasibil...
