The older adults have very frequent access to the Emergency Department (ED). aim of this study is explore ability some geriatric screening tools validated for ED predict outcomes (mortality, hospitalization, readmission and institutionalization) at 6 months.Methods. Older consecutively admitted Cagliari University’s between May December 2017 were enrolled. In patients scr...

Inverse synthetic aperture radar (ISAR) imaging of near-field targets is potentially useful in some specific applications, which makes it very important to efficiently produce high-quality image the target. In this paper, simplified target model with uniform linear motion applied imaging, overcomes complexity traditional algorithm. According signal model, method based on coordinate conversion a...

The role of glycoprotein (Gp) IIb/IIIa receptor antagonists remains controversial and these agents are infrequently utilized during non-ST-segment elevation acute coronary syndromes (NSTE-ACS) despite American Heart Association/American College of Cardiology guidelines. Despite recommendations, the NRMI-4 (National Registry of Myocardial Infarction 4) and CRUSADE (Can rapid risk stratification ...

This manuscript first introduces the fundamentals of Synthetic Aperture radar (SAR), there including the principle of the high resolution imaging capability, the processing required to focus the images, with its constraints and the different acquisition modes. Thereafter, it shows the potential ways to increase the imaging capabilities based on the concept of distributed SAR. Specifically both ...

Inverse synthetic aperture radar (ISAR) can achieve high-resolution two-dimensional images of maneuvering targets. However, due to the indeterminate relative motion between radar and target, ISAR imaging does not provide the three-dimensional (3-D) position information of a target and suffers from great difficulty in target recognition. To tackle this issue, a 3-D interferometric ISAR (InISAR) ...

Interactive Theorem Provers have a long tradition, going back to the 1970s when interaction was introduced as a concept in computing. The main provers in use today can be traced back over 20–30 years of development. As common traits there are usually strong logical systems at the bottom, with many layers of add-on tools around the logical core, and big applications of formalized mathematics or ...

Developing compressed sensing (CS) theory reveals that optimal reconstruction of an unknown signal can be achieved from very limited observations by utilizing signal sparsity. For inverse synthetic aperture radar (ISAR), the image of an interesting target is generally constructed by limited strong scattering centers, representing strong spatial sparsity. Such prior sparsity intrinsically paves ...

We describe the key concepts underlying the Isabelle/Isar implementation, including ML references for the most important functions. The aim is to give some insight into the overall system architecture, and provide clues on implementing applications within this framework. Isabelle was not designed; it evolved. Not everyone likes this idea. Specification experts rightly abhor trial-and-error prog...
