We prove a local limit theorem for the probability of a site to be connected by disjoint paths to three points in subcritical Bernoulli percolation on Zd, d ≥ 2 in the limit where their distances tend to infinity.
We prove that the spectrum of the almost Mathieu operator is absolutely continuous if and only if the coupling is subcritical. This settles Problem 6 of Barry Simon’s list of Schrödinger operator problems for the twenty-first century.
Methanol is a versatile chemical feedstock, fuel source, and energy storage material. Many reactions involving methanol are catalyzed by transition metal surfaces, on which hydrogen-bonded methanol overlayers form. As with water, the structure of these overlayers is expected to depend on a delicate balance of hydrogen bonding and adsorbate-substrate bonding. In contrast to water, however, relat...
background: public health burden from hazardous and harmful use of alcohol warrants drastic action throughout the world. although less alcohol related harm is anticipated in islamic countries, unrecorded alcohol remains a considerable concern which needs intelligent and realistic policy options. methods: in a descriptive study, records of chemically analyzed samples of alcohol obtained from ma...
Silica shows the effect of subcritical crack growth in humid environments. Measurements liquid water show increasing velocities when temperature is increased as was shown by Wiederhorn and Bolz. Since this has been generally found for glasses, called normal growth. For measurements on silica vapour environment astonishing decreasing crack-growth rate ν at an observed constant partial pressure e...
