An application specific inflexible FPGA (ASIF) is an FPGA with reduced flexibility that can implement a set of application circuits which will operate at mutually exclusive times. These circuits are efficiently placed and routed on an FPGA to minimize the total routing switches required by the architecture. Later all the unused routing switches are removed from the FPGA to generate an ASIF. An ASIF for a set of 17 MCNC benchmark circuits is found to be between 16 and 5 times smaller than a mesh-based unidirectional FPGA required to map any of these circuits. © 2010 IEEE. Source

In the context of microarray data analysis, biclustering aims to identify simultaneously a group of genes that are highly correlated across a group of experimental conditions. This paper presents a Biclustering Iterative Local Search (BILS) algorithm to the problem of biclustering of microarray data. The proposed algorithm is highlighted by the use of some original features including a new evaluation function, a dedicated neighborhood relation and a tailored perturbation strategy. The BILS algorithm is assessed on the well-known yeast cell-cycle dataset and compared with two most popular algorithms. © 2010 Springer-Verlag. Source

Anemia has been reported in 15-30% of patients with acute coronary syndrome. This percentage is even higher during the in-hospital phase, when hemoglobin tends to reach a "nadir" value, and usually a larger number of anemic patients compared to admission are discharged from the hospital. Both retrospective evaluation of randomized clinical trials and data coming from prospective or retrospective observational studies have prompted out a direct relationship between anemia and adverse outcomes in acute coronary syndrome patients. Although anemia has the potential to worsen the myocardial ischemic insult in acute coronary syndromes, it is not yet clear whether it is responsible per se for a higher incidence of death and myocardial infarction or it behaves just like an additional risk factor. Blood transfusions may correct anemia but also accentuate rather than attenuate both short-term and long-term rates of major adverse cardiac events, suggesting the opportunity of a restrictive use of this therapy in patients with low levels of hemoglobin who are hemodynamically stable. © 2011 Il Pensiero Scientifico Editore.

The AIS is one among the standards of radio communication system to be approved in the whole of the maritime environment. The adoption of AIS technology as a radio data maritime network that hopes for the rise of added values to the services of maritime industry allowing not only the safety of the ships and the environmental protection, but also improving the organization of the ports and the operations. The goal of this work consists on implementing the protocol layers of mobile AIS station on a DSP by using an embedded operating system: Visual DSP kernel. The solution comprises embedded software for both class A and class B AIS mobile equipment that can use CSTDMA or SOTDMA. © 2015 IEEE. Source

Since the early 1970s, intensive cardiac care is applied in coronary care units (CCUs), initially developed to treat lethal arrhythmias in patients with acute myocardial infarction. In the last decades, treatments offered within the CCUs have greatly expanded. Thus, these units have been called intensive cardiac care units (ICCUs) to reflect such evolution of care and the different epidemiology of patients admitted (subjects with acute coronary syndromes, acute and advanced heart failure, rhythm disturbances or severe valve dysfunction). At the same time, new drugs have become available but also different diagnostic, interventional and therapeutic procedures have been developed, resulting in better patient treatment and improved outcomes. These new devices require a high degree of specialization and specific skills that not every cardiologist is always used to. Consequently, specific training programs on intensive cardiac care for cardiologists working in ICCUs are clearly warranted. The present paper describes the advanced training programs on intensive cardiac care endorsed by the European Society of Cardiology and the Italian Association of Hospital Cardiologists (ANMCO). Both projects aim at improving current knowledge and skills of intensive cardiologists on specific pharmacologic and technical procedures, extending the competence of trained cardiologists to the management of critically ill cardiac patients, and uniforming the quality of care in any ICCU. © 2010 AIM Publishing Srl.
