We report a material-dependent critical temperature for ion beam sculpting of nanopores in amorphous materials under keV ion irradiation. At temperatures below the critical temperature, irradiated pores open at a rate that soon saturates with decreasing temperature. At temperatures above the critical temperature, the pore closing rate rises rapidly and eventually saturates with increasing tempe...

Temperature dependent changes in the mode of energy metabolism and in acid-base status were studied in the range from )1.7 to 26 oC in two populations of Arenicola marina collected in summer as well as in winter from intertidal flats of the North Sea (boreal) and the White Sea (subpolar). Extreme temperatures led to an accumulation of anaerobic end products, indicating the existence of both a l...

To date, the spin glass paradigm has been gainfully used in solving a number of optimization problems by devising a mapping between our understanding of spin interactions within a natural spin glass and the given optimization problems. Among the determining factors in a natural spin glass, phase transition is a physical phenomenon that is controlled by temperature. Depending on the spin glass’s...

A new meron cluster algorithm is constructed to study the finite temperature critical behavior of the chiral condensate in a (3+1) dimensional model of interacting staggered fermions. Using finite size scaling analysis the infinite volume condensate is shown to be consistent with the behavior of the form (Tc − T ) 0.314(7) for temperatures less than the critical temperature and m at the critica...
