Rhagovelia utria sp. nov. is part of the hirtipes group of species, based on the pronotum of the apterous form completely covering the mesonotum, the pronotum of the macropterous female without a posterior elevated projection, the abdomen of the apterous female with a median carina dorsally on mediotergites I–V, and the posterolateral margins of male abdominal segment VII surrounding the genital cavity lacking black denticles (Polhemus 1997). So far, 12 species are included in the hirtipes group, which has a disjunct distribution from Mexico to Colombia, and also in southeastern Brazil. The only species of the group heretofore recorded from Colombia is R. femoralis Champion, 1898, which can be distinguished from R. utria sp. nov. by the male hind tibia slightly arcuate on the basal two-thirds, with a large preapical spine; the male abdomen without a median carina dorsally; the female abdominal laterotergites lacking a mesally bowed and glabrous area adjacent to mediotergites III–V; and the male abdominal segment VIII with a low median carina ventrally (Bacon 1956, Polhemus 1997). In R. utria sp. nov., the male hind tibia is cylindrical and lacks a large preapical spine; the male abdomen has a median carina on mediotergites I–VI; the female laterotergites III–IV are mesally bowed; and the ventral carina of the male abdominal segment VIII is stronger than on anterior segments. Two other species of the group occur close to Colombia: R. chiriqui Polhemus, 1997, in Panama, and R. reclusa Polhemus, 1997, in Costa Rica. Rhagovelia chiriqui can be distinguished from R. utria sp. nov. by the goldenbrown bowed portion of the female laterotergites adjacent to mediotergites III–V and by the shape of the paramere (Polhemus 1997: fig. 93). Rhagovelia reclusa differs from the new species by the margins of female abdominal laterotergites adjoining the mediotergites V–VII flat and covered by numerous black setae, and the male hind trochanter with seven black pegs (Polhemus 1997). In R. utria sp. nov., the male hind trochanter has about 10 black pegs and two longer spines, the lateral portion of the female laterotergites are concolorous brown throughout the abdomen, the female abdominal laterotergites adjoining the mediotergites V–VII are expanded, and the paramere is shaped as in Fig. 3D.

Results of the Heart Protection Study: Can we still assume a class effect?
No full textStatins share several common features including the mechanism of action, i.e. inhibition of HMG-CoA reductase, as well as LDL-cholesterol (LDL-C) and triglyceride lowering properties. However, statins show minor differences in chemical structure, lipophilicity that could translate into a different pharmacological properties. For example, simvastatin exerted a more favorable effect on HDL-C levels than did atorvastatin when higher doses of the two drugs were compared. Finally, the major considerations to chose between statins for CVD patient therapy include clinical benefits and safety (i.e. evidence-based medicine). Primary prevention trials with pravastatins and lovastatin and secondary prevention trials with pravastatin, fluvastatin and simvastatin have established the clinical benefits of statins. In addition, HPS study was designed to investigate the benefits of simvastatin 40 mg in a broad range of patients at high risk for heart disease including women, the elderly and those with a history of hearth attacks, diabetes, hypertension or vascular disease. The results show the ability of simvastatin to reduce all causes of mortality, vascular death and cardiovascular morbidity. The trial also confirms the safety of simvastatin 40 mg although 60% of patients were receiving additional pharmacological treatment. In summary, it appears that statins are not the same and the choice of the more appropriate statin in high-risk patients should be driven by the evidence-based medicine both in terms of safety and efficacy
A Relational Unsupervised Approach to Author Identification
No full textIn the last decades speaking and writing habits have changed.
Many works faced the author identification task by exploiting frequencybased
approaches, numeric techniques or writing style analysis. Following
the last approach we propose a technique for author identification
based on First-Order Logic. Specifically, we translate the complex data
represented by natural language text to complex (relational) patterns
that represent the writing style of an author. Then, we model an author
as the result of clustering the relational descriptions associated to the
sentences. The underlying idea is that such a model can express the typical
way in which an author composes the sentences in his writings. So,
if we can map such writing habits from the unknown-author model to
the known-author model, we can conclude that the author is the same.
Preliminary results are promising and the approach seems viable in real
contexts since it does not need a training phase and performs well also
with short texts
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
Detection of weak stochastic forces in a parametrically stabilized micro-optomechanical system
Get PDFMeasuring a weak force is an important task for micromechanical systems, both when using devices as sensitive detectors and, particularly, in experiments of quantum mechanics. The optimal strategy for resolving a weak stochastic signal force on a huge background (typically given by thermal noise) is a crucial and debated topic, and the stability of the mechanical resonance is a further, related critical issue. We introduce and analyze the parametric control of the optical spring, which allows us to stabilize the resonance and provides a phase reference for the oscillator motion, yet conserving a free evolution in one quadrature of the phase space. We also study quantitatively the characteristics of our micro-optomechanical system as detector of stochastic force for short measurement times (for quick, high-resolution monitoring) as well as for the longer-term observations that optimize the sensitivity. We compare a simple strategy based on the evaluation of the variance of the displacement which is a widely used technique) with an optimal Wiener-Kolmogorov data analysis. We show that, due to the parametric stabilization of the effective susceptibility, we can more efficiently implement Wiener filtering, and we investigate how this strategy improves the performance of our system. We finally demonstrate the possibility to resolve stochastic force variations well below 1% of the thermal noise.MicroelectronicsElectrical Engineering, Mathematics and Computer Scienc
