Abstract We estimate the critical slip-weakening distance on earthquake faults by using a new approach, which is independent of the estimate of fracture energy or radiated seismic energy. The approach is to find a physically based relation between the breakdown time of shear stress Tb, the time

Abstract The single-body mass-spring analog model has been largely used to simulate the recurrence of earthquakes on faults described by rate- and state-dependent rheology. In this paper, the fault was assumed to be governed by the clas-sical slip-weakening (SW) law in which the frictional

The focus of this article is on the relationship between research and education. The argument is that recent policy developments and the increasing emphasis on com-mercialisation and profitability of university activities weakens the connection of education and research. In this article, general

Abstract. In this paper we propose substructural propositional logic obtained by da Costa weakening of the intuitionistic negation. We show that the positive frag-ment of the da Costa system is distributive lattice logic, and we apply a kind of da Costa weakening of negation, by preserving

the weak formulation a system of PDE with h αβ as unknowns. The existence of solutions depends both on the geometry of the shell and on the choice of h. We carry through the study of four representative geometries of shells and identify in each case a special admissibility functional space for h. 1

Soil carbon (C) and nitrogen (N) stoichiometry is a main driver of ecosystem functioning. Global N enrichment has greatly changed soil C: N ratios, but how altered resource stoichiometry influences the complexity of direct and indi-rect interactions among plants, soils, and microbial communities

Luby and Rackoff [27] showed a method for constructing a pseudo-random permutation from a pseudo-random function. The method is based on composing four (or three for weakened security) so called Feistel permutations, each of which requires the evaluation of a pseudo-random function. We reduce

We estimate the critical slip-weakening distance on earthquake faults by using a new approach based on a relation between the breakdown time of shear stress, the time of peak slip-velocity, and the prescribed slip-weakening distance, which is independent of the fracture energy or radiated seismic

The idea of a sister-group relationship between the cephalopod superorders Decabrachia (squids and cuttlefishes) and Vampyropoda (octopods, cirroctopods and vampire squid) has been widely accepted since Jeletzky (1966: fig. 2). In their phy-logenetic analyses, Berthold & Engeser (1987) and Engeser & Bandel (1988) regarded the presence of suckers as a character state that supports the monophyly of what they called the ‘sucker-bearing Coleoidea’. In 1997, Haas introduced the terms ‘Neocoleoidea ’ for coleoid groups with living representa-tives and ‘Palaeocoleoidea ’ for a group of hook-bearing coleoids also known as ‘Belemnoidea’, which was thought to have disappeared at the end of the Cretaceous.
