Centenários modernistas: Ulysses e a Terra Devastada

The Ulysses perspective

Current sheets from Ulysses observation

Current sheet is a significant source of solar wind MHD turbulence intermittency. It has long been recognized that these structures can arise from non-linear interactions of MHD turbulence. Alternatively, they may also be relic structures in the solar wind that have a solar origin, e.g., magnetic walls of flux tubes that separate solar wind plasma into distinct parcels. Identifying these struct...

Terra Firma - Forme Dermatosis . a Case Report

Terra firma-forme dermatosis is a cutaneous discoloration. ‘Dirty’ brown grey cutaneous patches and plaques that can be rid off by forceful swabbing with alcohol pads characterize it. The pathogenesis has been attributed to abnormal and delayed keratinization. It poses no medical threat. A 40-year-old male patient presented to the Department of Dermatology with a 2-3 month history of persistent...

ULYSSES: A Lattice-Based Multiple Interaction Strategy Retrieval Interface

We present a two-stage system for information exploration and retrieval. The first stage, named GALOIS, organizes the information contained into a database into a particular lattice structure; the second stage, named ULYSSES, is a visual interface to access the structure built in the earlier stage. In this paper we focus on the latter. ULYSSES is based on a tight integration of traditional and ...

TERRA Incognita at chromosome ends.

Telomeres are transcribed in long noncoding RNA named TERRA. Although TERRA functions have been extensively investigated, the role of TERRA in telomerase recruitment and regulation is still elusive. In this issue of EMBO Reports, Moravec et al report in Schizosaccharomyces pombe that telomere shortening induces the expression of TERRA [1]. They show that polyadenylated TERRA molecules specifica...
