OBJECTIVE It is believed that shock-induced intramural virtual electrodes (IVE) play a critical role in defibrillation. IVE were recently demonstrated in the porcine left ventricle (LV), but their origin remains unknown. Macroscopic optical mapping showed that strong shocks induce IVE of only one polarity, which contradicts theoretical predictions. It is hypothesized that IVE have a microscopic...
Iterative eigenvalue solvers for large, sparse matrices may miss some of the required eigenvalues that are of high algebraic multiplicity or tightly clustered. Block methods, locking, a-posteriori validation, or simply increasing the required accuracy are often used to avoid missing or to detect a missed eigenvalue, but each has its own shortcomings in robustness or performance. To resolve thes...
The article addresses creation of a mathematical model for real problem regarding time coordination periodic train connections operated on single-track lines. individual are dispatched with predefined tact, and their arrivals at departures to railway stations (transfer nodes) need be coordinated one another. In addition, because the lines, trains that pass each other in must also coordinated. T...
We conducted a multicentre test-negative case-control study in 27 hospitals of 11 European countries to measure 2015/16 influenza vaccine effectiveness (IVE) against hospitalised influenza A(H1N1)pdm09 and B among people aged ≥ 65 years. Patients swabbed within 7 days after onset of symptoms compatible with severe acute respiratory infection were included. Information on demographics, vaccinati...
This paper presents a procedure to generate judgment determiners, e.g., many, few. Although such determiners carry very little objective information, they are extensively used in everyday language. The paper presents a precise characterization of a class of such determiners using three semantic tests. A conceptual representation for sets is then derived from this characterization which can serv...
MicroRNAs (miRNAs) are noncoding RNAs that can regulate gene expression. Several hundred genes encoding miRNAs have been experimentally identified in animals, and many more are predicted by computational methods. How can new miRNAs be discovered and distinguished from other types of small RNA? Here we summarize current methods for identifying and validating miRNAs and discuss criteria used to d...
