The goal of this work is to develop a phase-field fracture model capable of capturing mixed-
mode fracture propagation behavior. In nature, failure of rocks and rock-like materials is usually
accompanied by the propagation ...
Dans le système suisse de formation professionnelle, les places d’apprentissage offertes par des entreprises formatrices représentent quatre cinquièmes des places de formation, c’est-à-dire une part importante de l’offre ...
Eine genaue Positionsbestimmung mittels GNSS basiert auf einem präzisen Signalempfang. Im Falle von Trägerphasenmessung stellt ein gleichförmiger Kugelstrahler eine ideale Empfängerantenne dar. Abweichungen von dieser ...

GNSS based positioning and navigation always require perfect synchronization between the receiver and satellites clock. Further, due to the limited frequency stability of the GNSS receiver’s internal oscillator, an additional ...
Mit dem Wahrheitsbegriff ist ein entscheidendes Thema der Philosophie bzw. der sich bildenden Wissenschaftstheorie im 20 Jh. angesprochen. Wichtige Aufsätze von Max Horkheimer aus den 30iger Jahren kreisen um dieses Thema. ...

Umami is one of the five basic tastes beside sweet, bitter, sour, and salty. It is well known in various fermented food preparations like soy sauce. Umami represents the taste of L-glutamate and 5’-ribonucleotides, such ...
The representation theory of the Virasoro algebra in the case of a logarithmic conformal field theory is considered. Here, indecomposable representations have to be taken into account, which has many interesting consequences. ...
We consider pure SU(2) Yang–Mills theory on four-dimensional de Sitter space dS 4 and construct smooth and spatially homogeneous classical Yang–Mills fields. Slicing dS 4 as ℝ×S 3 , via an SU(2)-equivariant ansatz we reduce ...

Rapidly expanding urban agglomerations create various industrial and developmental challenges, and trigger debates about globalization in many fields especially in relation to basic need, self-resilience, and eco-development. ...
I explain how to construct noncommutative BPS configurations in four and lower dimensions by solving linear matrix equations. Examples are instantons in D=4 Yang-Mills, monopoles in D=3 Yang-Mills-Higgs, and (moving) ...

This paper gives an analytic description of why and how an instructional writing program on the improvement of cross-genre writing skills in German secondary grade level has been designed and implemented. From a diagnostic ...
An international network of laser-interferometric gravitational wave detectors is nearing the end of the main commissioning phase and will soon enter into an extended observational period, collecting data for a duration ...
Upon reactivation from latency and during lytic infections in neurons, alphaherpesviruses assemble cytosolic capsids, capsids associated with enveloping membranes, and transport vesicles harboring fully enveloped capsids. ...
An insolvency administrator replaces the manager of an insolvent firm to devise and organize a liquidation or reorganization plan in the creditors’ interest. In the course of the process, the insolvency administrator ...
