Design and Test of the Off-Detector Electronics for the CMS Barrel Muon Trigger

Drift Tubes chambers are used in the CMS barrel for tagging the passage of high Pt muons generated in a LHC event and for triggering the CMS data read out. The Sector Collector (SC) system synchronizes the track segments built by trigger modules on the chambers and deliver them to reconstruction processors (Track Finder, TF) that assemble full muon tracks. Then, the Muon Sorter (MS) has to select the best four candidates in the barrel and to filter fake muons generated by the TF system redundancy. The hardware implementations of the Sector Collector and Muon Sorter systems satisfy radiation, I/O and fast timing constraints using several FPGA technologies. The hardware was tested with custom facilities, integrated with other trigger subsystems, and operated in a beam test. A test beam on a 40 MHz bunched beam validated the local trigger electronics and off-detector prototype cards and the synchronization tools. The CMS Magnet Test and Cosmic challenge in 2006 proved stable and reliable operation of the Drift Tubes trigger and its integration with other trigger systems and with the readout system. Constraints, design, test and operation of the modules are presented

DT Sector Collector electronics design and construction

The CMS detector at LHC is equipped with Drift Tubes (DT) chambers for muon detection and triggering in the barrel region. The Sector Collector (SC) modules collect the track segments reconstructed by on-chamber trigger electronics. Data from different chambers are aligned in time and sent to the subsequent reconstruction processors via optical links. Several FPGA devices performing the processing of the data were designed in VHDL, including spy features to monitor the trigger data flow. A test jig was set up with custom hardware and software in order to fully validate final production boards. Installation and commissioning in CMS provided first experience with the synchronization and monitoring tools

Análise econômica e de risco da primeira safra de canola tropicalizada no Distrito Federal e Bahia.

O objetivo deste estudo foi avaliar o resultado econômico da primeira safra de canola em 06 propriedades agrícolas do Distrito Federal e Bahia. Fez-se levantamento de dados primários de custos de produção e produtividade, a fim de avaliar a renda líquida e o risco econômico devido a variações na produtividade em sistemas de cultivos de sequeiro e irrigado. Utilizou-se o método de Monte Carlo nas simulações de risco. Buscou-se avaliar também a percepção de impacto ambiental, social e econômico dos produtores, por meio de entrevistas, utilizando o método Ambitec-Agro. Os resultados econômicos mostram que a canola é lucrativa, com renda líquida média de R$460,05/ha e R$ 1.425,80/ha, nos cultivos de sequeiro e irrigado, respectivamente. A probabilidade de prejuízo (renda líquida menor ou igual a zero) frente à oscilação na produtividade é muito baixa no cultivo de sequeiro (1,3%) e 0% no irrigado. Conclui-se que a cultura da canola tem grande potencial de integrar o sistema de produção de grãos nessas regiões, pois apresentou desempenho produtivo surpreendente frente às condições climáticas adversas verificadas nessas localidades, em 2021, apresentando resultados econômicos positivos e perspectivas de impactos socioeconômicos e ambientais relevantes na percepção dos produtores.60º Congresso da SOBER

The Importance of Mehran Score to Predict Acute Kidney Injury in Patients with TAVI: A Large Multicenter Cohort Study

Background: Transcatheter aortic valve implantation (TAVI) has developed as an alternative to surgery for symptomatic high-risk patients with aortic stenosis (AS). An important complication of TAVI is acute kidney injury. The purpose of the study was to investigate if the Mehran Score (MS) could be used to predict acute kidney injury (AKI) in TAVI patients. Methods: This is a multicenter, retrospective, observational study including 1180 patients with severe AS. The MS comprised eight clinical and procedural variables: hypotension, congestive heart failure class, glomerular filtration rate, diabetes, age >75 years, anemia, need for intra-aortic balloon pump, and contrast agent volume use. We assessed the sensitivity and specificity of the MS in predicting AKI following TAVI, as well as the predictive value of MS with each AKI-related characteristic. Results: Patients were categorized into four risk groups based on MS: low (≤5), moderate (6–10), high (11–15), and very high (≥16). Post-procedural AKI was observed in 139 patients (11.8%). MS classes had a higher risk of AKI in the multivariate analysis (HR 1.38, 95% CI, 1.43–1.63, p < 0.01). The best cutoff for MS to predict the onset of AKI was 13.0 (AUC, 0.62; 95% CI, 0.57–0.67), whereas the best cutoff for eGFR was 42.0 mL/min/1.73 m2 (AUC, 0.61; 95% CI, 0.56–0.67). Conclusions: MS was shown to be a predictor of AKI development in TAVI patients

Work Plans of the EUROTeV Technical Work Packages for 2005-2007

This report summarises the status of the work in the seven scientific Work Packages of EUROTeV as presented during the ILC-European Regional Meeting at Royal Holloway in June 2005. The purpose of the meeting was to monitor the progress and to contrast the developments inside EUROTeV with the worldwide developments of the GDE.
