These lecture notes are dedicated to Dierk Rainer on the occassion of his 60th birthday in 2001. He pioneered the systematic treatment of the low-energy scale in the electronic theory of condensed matter.

We read the interesting paper by Pardi et al on the epidemiology of microscopic colitis in Olmsted County, Minnesota, USA (Gut 2007; 56: 504–8). They concluded that the incidence of microscopic colitis increased significantly over time, and by the end of the study, the incidence and prevalence were significantly higher than reported previously. In fact, compared with other epidemiological studi...

pHN1122-1 carrying bla(CTX-M-55), from an Escherichia coli isolate from a dog, was completely sequenced. pHN1122-1 has an IncI2 replicon and typical IncI2-associated genetic modules, including mok/hok-finO-yafA/B, nikABC, and two transfer regions, tra and pil, as well as a shufflon. bla(CTX-M-55) is found within a 3.084-kb ISEcp1 transposition unit that includes a fragment of IncA/C plasmid bac...

We begin with an introduction of superconductivity by giving a brief history of the phenomenon. The phenomenological Ginzburg–Landau theory and the microscopic theory of Bardeen, Cooper and Schrieffer are outlined. In view of recently available multi-band superconductors, relevant theories of both types are discussed. Unlike the traditional GL theory an extended GL theory is developed relevant ...

We study how black hole superradiance appears in string microscopic models of rotating black holes. In order to disentangle superradiance from finite-temperature effects, we consider an extremal, rotating D1-D5-P black hole that has an ergosphere and is not supersymmetric. We explain how the microscopic dual accounts for the superradiant ergosphere of this black hole. The bound 0 < ω < mΩH on s...

The erotic literature of ancient China constitutes an inexhaustible source of information on ejaculation control techniques, which remain valid today and are the source of the techniques advocated by contemporary sex therapists. To cite this journal: Androl. 20 (2010).

Although the relationship between minimal free resolutions and Koszul cohomology has been known for a long time, it has been difficult to find a way to fully utilize the " exterior " nature of the Koszul classes. The technique used here seems to be one way to begin to do this. We prove a conjecture of Eisenbud-Koh-Stillman on linear syzygies and in consequence a conjecture of Lazarsfeld and mys...

Before proceeding, we make the following observations: First, for each student, applying to a college dominates not applying at all. Second, since a student does not know the score and the student’s preference is independent of the score, the student’s application depends solely on the preference. Third, since each student’s preference depends on the state, the mass of students applying to each...
