We present a seismogenic source model for site-specific probabilistic seismic hazard assessment at the sites of Swiss nuclear power plants. Our model is one of four developed in the framework of the PEGASOS project; it contains a logic tree with nine levels of decision-making. The two primary sources of input used in the areal zonation developed by...

We propose a unifying framework for studying extremal problems related to graph minors. This framework relates the existence of a large minor in a given graph to its expansion properties. We then apply the developed framework to several extremal problems and prove in particular that: (a) Every \documentclass[12pt]{minimal} \usepackage{amsmath} \use...

For an arbitrary infinite field k of characteristic p > 0, we describe the structure of a block of the algebraic monoid Mn(k) (all n × n matrices over k), or, equivalently, a block of the Schur algebra S(n, p), whose simple modules are indexed by p-hook partitions. The result is known; we give an elementary and self-contained proof, based only on a...

UV-induced transformations of colored dissolved organic matter (CDOM, which is part of dissolved organic matter, DOM) affect CDOM absorption properties resulting in the loss of color (referred to as photobleaching). CDOM photobleaching increases the penetration depths of the damaging UV-B radiation into water bodies and strongly depends on the wave...

In this note we continue the study of spectral properties of a self-adjoint analytic operator function A(z) that was started in [5]. It is shown that if A(z) satisfies the Virozub–Matsaev condition on some interval Δ0 and is boundedly invertible in the endpoints of Δ0, then the ‘embedding’ of the original Hilbert space \documentclass[12pt]{minimal}...

Geometric and summability properties of the integration operator associated to a vector measure m can be translated in terms of structure properties of the space L1(m). In this paper we study the cases of the integration operator being: (i) p-concave on Lp(m), or (ii) positive p-summing on L1(m) (where \documentclass[12pt]{minimal} \usepackage{amsm...
