Harald Räcke [STOC 2008] described a new method to obtain hierarchical decompositions of networks in a way that minimizes the congestion. Räcke’s approach is based on an equivalence that he discovered between minimizing congestion and minimizing stretch (in a certain setting). Here we present Räcke’s equivalence in an abstract setting that is more general than the one described in Räcke’s work,...

Inspired by the European debt crisis of 2010, this paper provides a theoretical framework to analyze the dynamics of the sovereign debt ∗This is preliminary indeed. The results have not yet been checked with sufficient care, despite multiple presentations of earlier drafts. We are thankful to our discussants so far. We are particularly thankful for an insightful discussion by Fernando Broner at...

One of the main contributions which Harald Niederreiter made to mathematics is related to pseudorandom sequences theory. In this paper we study several measures for asserting the quality of pseudorandom sequences, involving generalizations of linear complexity and lattice tests and relations between them.

Kaposi’s sarcoma is vascular neoplasia, with purplish, infiltrative lesions and the possibility of affecting viscera or lymph nodes, that can be classified into 4 categories: epidemic (related to HIV infection), classical (elderly men in Mediterranean basin), endemic (Africa) iatrogenic (immunosuppressive therapy). Case presentation Will illustrate case a 69-year-old man, without personal patho...

This commentary presents my compositional work of the last two years. It consists of musical pieces that follow a formal approach emphasising static, self-enclosed musical situations. Designed to avoid processual ways of formal organisation, these pieces present collections of rich instrumental textures that do not evolve; they point toward a music of 'being' rather than 'becoming'. Drawing on ...

BACKGROUND Germline mutations of the VHL gene cause von Hippel-Lindau syndrome (VHL). In southern Germany, a specific mutation in this gene, c.505 T>C, is one of the most frequent alterations owing to a founder effect. METHODS This study was conducted to evaluate morbidity, specific clinical risk profile, and mortality among a series of VHL c.505 T/C mutation carriers. A total of 125 eligible...

Many virus infections give rise to surprisingly limited T-cell responses directed to very few immunodominant determinants. We have been examining the cytotoxic T-lymphocyte (CTL) response to herpes simplex virus type 1 (HSV-1) infection. Previous studies have identified the glycoprotein B-derived peptide from residues 498 to 505 (gB(498-505)) as one of at least three determinants recognized by ...
