1-loop contribution to the dynamical exponents in spin glasses

We evaluate the corrections to the mean field values of the $x$ and the $z$ exponents at the first order in the $\epsilon$-expansion, for $T=T_c$. We find that both $x$ and $z$ are decreasing when the space dimension decreases.Comment: 12 pages 3 Postscript figure

Factors that influence career progression among postdoctoral clinical academics: a scoping review of the literature

Background: The future of academic medicine is uncertain. Concerns regarding the future availability of qualified and willing trainee clinical academics have been raised worldwide. Of significant concern is our failure to retain postdoctoral trainee clinical academics, who are likely to be our next generation of leaders in scientific discovery. / Objectives: To review the literature about factors that may influence postdoctoral career progression in early career clinical academics. / Design: This study employed a scoping review method. Three reviewers separately assessed whether the articles found fit the inclusion criteria. / Data sources: PubMed, Scopus, Web of Science and Google Scholar (1991–2015). / Article selection: The review encompassed a broad search of English language studies published anytime up to November 2015. All articles were eligible for inclusion, including research papers employing either quantitative or qualitative methods, as well as editorials and other summary articles. / Data extraction: Data extracted from included publications were charted according to author(s), sample population, study design, key findings, country of origin and year of publication. / Results: Our review identified 6 key influences: intrinsic motivation, work–life balance, inclusiveness, work environment, mentorship and availability of funding. It also detected significant gaps within the literature about these influences. / Conclusions: Three key steps are proposed to help support postdoctoral trainee clinical academics. These focus on ensuring that researchers feel encouraged in their workplace, involved in collaborative dialogue with key stakeholders and able to access reliable information regarding their chosen career pathway. Finally, we highlight recommendations for future research

Mobile learning for the integration of groups that risk being marginalized

Social inclusion and cohesion are two of the objectives that the European Union has very often proclaimed in its documents, in the past ten years. At the same time, community policies have emphasized the role that ICTs can play to encourage and support participation and integration opportunities of disadvantaged citizens. Within this context, the ENSEMBLE project, presented here, aims at developing a strategy of use of ICTs to promote socio-cultural integration of immigrant citizens by using technologies such as MP3 players and mobile phones, and by experimenting instructional methods and communication models suitable for the adopted instruments. The present paper focuses particularly on the educational communication design of MMS messages

Soil erosion evaluation in a small watershed in Brazil through 137 Cs fallout redistribution analysis and conventional models

An investigation of rates and patterns of soil erosion on agricultural land cultivated with sugarcane was undert a ken using the 137Cs technique, USLE (Universal Soil Loss Equation) and WEPP (Water Erosion Prediction Project) model. The study was carried out on a representative catchment of a small watershed of the Piracicaba river basin, State of São Paulo, Brazil, called Ceveiro watershed, well known for its severe soil degradation caused by erosion. The results from the 137Cs technique indicate that most part of the studied area (94%) are eroded at erosion rates that go up to 59 Mg ha-1 y-1, with a weighted average rate of 23 Mg ha-1 y-1 . The weighted average rate of infield deposition and sediment retrieval that occurs in only 6% of the total area was estimated to be around 12 Mg ha-1 y-1 . These values led to very high net soil loss from the field, with rates of the order of 21 Mg ha-1 y-1 , which represents a sediment delive ry ratio of 97%. A linear correlation between soil erosion rate estimated by the 137Cs technique and the amount of available K in the top soil layer (0-20 cm) was observed. Based on this correlation the estimated amounts of net and gross K loss in the grid area due to soil erosion were of 0.2 and 1.52 kg ha-1 y-1, respectively. The erosion rate estimated by USLE was 39 Mg ha-1 y-1 and by WEPP model 16.5 Mg ha-1 y-1 with a sediment delivery of 12.4 Mg ha-1 y-1 (75%). The results are a confirmation that the soil conservation practices adopted in the area are very poor and can explain the high siltation level of water reservoirs in the watershed

Splenic Flexure Volvulus Presenting with Peritonitis: Case Report and Review of the Literature

Splenic flexure is the rarest site for colonic volvulus. We report a case of an 18 years old woman, admitted to our department for tender and sore abdomen, nausea and vomiting. A barium enema reported a splenic flexure volvulus. Explorative laparotomy revealed peritonitis originating from an extensive gangrene of splenic flexure of the colon, caused by 360° volvulus. The colon was encircled by omentum at its base. A resection with primary anastomosis was performed. Anatomic abnormalities and partial intestinal malrotation are the main pathogenetic cause

A Numerical Study of Ultrametricity in Finite Dimensional Spin Glasses

We use a constrained Monte Carlo technique to analyze ultrametric features of a 4 dimensional Edwards-Anderson spin glass with quenched couplings J=\pm 1. We find that in the large volume limit an ultrametric structure emerges quite clearly in the overlap of typical equilibrium configurations.Comment: 8 one column pages, latex, 4 figures with epsfig.st

Low-cost smartphone-based speed surveying methods in proximity to traffic calming devices

The study is aimed at investigating the effectiveness of two smartphone applications for surveying speeds of moving objects. These applications are used for urban speed measurements. Once the most reliable application was selected among the available ones, its outputs were calibrated by using the speed from the GPS system mounted on the test vehicle as a benchmark. Thereafter, an experimental test was conducted for monitoring the influence of a raised crossing on the vehicle speeds in the urban environment, by using the selected smartphone application
