A procedure to filter the ICARUS digitized data is presented. The final multi-kiloton detector will provide raw data at a rate of the order of 100
Gbytes/s and therefore a crucial element of the ...acquisition chain will be the on-line data reduction system. A filter has been developed to process the signals and to tag the meaningful data. The hit detection efficiency has been evaluated on a sample of signals obtained from cosmic rays events in the 3
t ICARUS prototype. Its robustness has been tested also on simulated events with different signal to noise ratio. The hit finder hardware implementation is also presented.
Italy is the European country where firms with fewer than 10 employees account for the largest share of value added and employment. On the basis of data from the company balance sheets and the ...Central Credit Register during the period 2003-2010, this work contributes to the analysis of these companies describing their economic and financial conditions and their relations with banks based on a sample of about 500,000 companies, of which more than 400,000 are classified as micro-enterprises. On average, they have lower profitability and higher debt, largely bank debt, than the other size classes. The proportion of loans made by the partners and shareholders is significant, a feature that can mitigate some of the risks associated with their weaker financial conditions. Econometric estimates indicate that micro-enterprises must provide more guarantees and pay higher rates of interest. In all aspects investigated in our work, the heterogeneity of micro-enterprises is much higher than for the other size classes, which suggests broad scope for future research.
The clinical effects of intra‐articular betamethasone together with hyaluronan (βM/HA) and treatment with a defocalized carbon dioxide laser on acute traumatic arthritis of the fetlock joint were ...assessed. The horses in these studies were selected using a thorough lameness examination, including intra‐articular anaesthesia abolishing the lameness. This investigation comprised an observer‐blind study, including 10 sport horses (10 joints), and a prospective study, including 180 sport horses (333 joints). In both studies, the material was divided into two groups treated with either βM/HA or a carbon dioxide laser. The treatment doses were 12 mg of βM, 20 mg of HA or 60 J/cm2 of treated area. Convalescence before training was 21 days for both groups in the observer‐blind study. In the prospective study, convalescence in the βM/HA group was 21 days but was only 7 days for the laser‐treated group. In the observer‐blind study, three of five treated joints recovered in both cohorts. In the prospective study, the groups had significantly different recovery rates – 68% of the βM/HA‐treated joints and 80% of the carbon dioxide laser‐treated joints. These results indicate that the defocalized carbon dioxide laser should be an applicable mode of treatment of acute traumatic synovitis in horses. However, the biochemical functions related to carbon dioxide laser treatment require further elucidation.
The purpose of the work here presented consists in the evaluation of the performance of CAD (Computer Aided Detection) systems for automated lung nodule identification on multislice CT examinations ...based on different analysis approaches and on their combination. Three different CADe systems, the CAM CAD (Channeler Ant Model), the RGVP CAD (Region Growing Volume Plateau) and the VBNA CAD (Voxel Based Neural Approach) were tested on public research datasets and evaluated in terms of FROC (Free-response Receiver Operating Characteristics) curves both individually and combined.

Accurate information relating to the impact of fire on the environment and the way it is distributed throughout the burned area is critical for short-term mitigation and rehabilitation treatments. ...The aim of this chapter is to review the role of Remote Sensing (RS) in estimating burn severity. Initially, the terminology was clarified since two different terms are usually used in the literature: fire and burn severity. Methods and techniques that have been employed to estimate burn severity on the ground and by RS were reviewed. Special attention was paid to the different type of sensors that are used in previously conducted studies. Finally, the future trends in researches related to remote sensing of burn severity were identified.
Objetivo: analisar 54 transfusões intravasculares intra-uterinas (TIVs), ressaltando complicações do procedimento e morbimortalidade perinatal. Material e Métodos: fetos submetidos a TIVs na Clínica ...Materno-Fetal e Maternidade Carmela Dutra (Florianópolis, SC), entre janeiro de 1992 e agosto de 1997, foram incluídos no estudo. As características das gestantes, dados relativos ao procedimento e ao recém-nascido foram tabulados para análise e apresentados de forma descritiva, utilizando-se percentagem, média, desvio padrão, mediana, variação e risco relativo (RR) com intervalo de confiança de 95% (IC) conforme apropriado. Resultados: foram realizadas 50 TIVs e quatro ex-sangüíneo transfusões em 21 fetos. Houve quatro óbitos (20%), três dos quais (75%) ocorridos em fetos hidrópicos. A idade gestacional média quando da primeira transfusão foi de 29,1 semanas. A concentração média de hemoglobina foi de 5,69 mg/dl. A taxa de mortalidade decorrente do procedimento foi de 7,4%. A idade gestacional média ao nascimento foi 33,9 semanas e o peso médio foi 2.437 gramas. Sessenta e cinco por cento dos recém-nascidos receberam ex-sangüíneo transfusão complementar. Conclusão: a taxa de mortalidade por procedimento (7,4%) foi semelhante à relatada na literatura mundial. A taxa de mortalidade perinatal (20%) foi mais elevada do que a relatada na literatura estrangeira, mas inferior à relatada em estudo conduzido no Brasil, no qual a prevalência de fetos hidrópicos foi semelhante.Objective: to report 54 intrauterine intravascular transfusions (IITs), describing procedure related complications and associated perinatal morbidity and mortality. Methods: fetuses undergoing IITs at Clínica Materno-Fetal and Maternidade Carmela Dutra, Florianópolis, SC, between January 1992 and August 1997 were included in the study. Patients demographics, procedure and newborn related data were tabulated for analysis and presented in descriptive form, using percentage, mean, standard deviation, median, range and relative risk (RR) with 95% confidence interval as appropriate. Results: fifty IITs and four exchange transfusions were performed in twenty-one fetuses. There were four deaths (20%), three of which occurred (75%) in hydropic fetuses. Mean gestational age at the time of the first IIT was 29.1 weeks, the mean hemoglobin concentration was 7.1 mg/dl and the mean rise in hemoglobin level per procedure was 5.69 mg/dl. Procedure related mortality rate was 7.4%. Mean gestational age at birth was 33.9 weeks and mean birth weight was 2,437 grams. Sixty-five percent of the newborns received complementary exchange transfusions. Conclusion: the procedure related mortality rate was 7.4%, similar to the mortality rate reported in the world literature. The perinatal mortality rate (20%) was higher than that reported in other countries but lower than the perinatal mortality rate reported in a study conducted in Brazil, with a similar prevalence of hydropic fetuses.
