Wireless sensor systems often fail to provide measurements with uniform time spacing.Measurements can be delayed or even miss completely.Resampling to uniform intervals is necessary to satisfy the requirements of subsequent signal processing.Common resampling algorithms, based on symmetric finite impulse response (FIR) filters, entail a group delay
Abstract The physics of complex systems stands to greatly benefit from the qualitative changes Planter in data availability and advances in data-driven computational methods.Many of these systems can be represented by interacting degrees of freedom on inhomogeneous graphs.However, the lack of translational invariance presents a fundamental challeng
Abstract Background The decision on whether to operate on a sick Fixed Blade Hunting elderly person with an intra-abdominal emergency is one of the most difficult in general surgery.A predictive risk-score would be of great value in this situation.Methods A Medline search was performed to identify those predictive risk-scores relevant to sick elder
BACKGROUND: Few data are available on the prevalence of erosive and severe esophagitis in Western countries.OBJECTIVE: Wall stickers To retrospectively determine the prevalence and the factors predicting erosive esophagitis and severe esophagitis in a large series of endoscopies in Spain.DESIGN: Retrospective observational study.A multivariate anal
Non-repudiation protocols are aimed at exchanging digital messages and irrefutable receipts between two mistrusting parties over the Internet, which form the cornerstones of modern secure network transactions.Timeliness is a key security property of non-repudiation protocols, which ensures that protocol agents can terminate their execution within a
