Progress in cardiac rehabilitation demands that rehabilitation efforts for the patient after myocardial infarction or aortocoronary bypass surgery be integrated into a comprehensive program of acute and ambulatory cardiac care. To permit a more rapid return of coronary patients to a normal or near-normal lifestyle and role in society, further delineation of the scientific bases for all componen...

A comprehensive effort in photodynamical ab initio simulations of the ultrafast deactivation pathways for all five nucleobases adenine, guanine, cytosine, thymine, and uracil is reported. These simulations are based on a complete nonadiabatic surface-hopping approach using extended multiconfigurational wave functions. Even though all five nucleobases share the basic internal conversion mechanis...

A comprehensive treatment of the theory of Gröbner bases is far beyond the scope of this tutorial. The reader is reffered to [1], [2], [3] for a more detailed discussion. Gröbner bases offers a powerful algorithmic criterion for the existence of solutions to a system of algebraic equations over algebraically closed fields. While the theory is rich and builds on the theory of Ideals and Varietie...

Preservation Planning, which deals with selecting the most appropriate preservation action to be applied to digital objects, is an important step in any digital preservation activity. Comprehensive Preservation Planning depends on the availability of identified alternatives of preservation actions, which are for example file format migrations to migrate data in an outdated format to one that ha...

g-frames in hilbert spaces are a redundant set of operators which yield a repre-sentation for each vector in the space. in this paper we investigate the connection betweeng-frames, g-orthonormal bases and g-riesz bases. we show that a family of bounded opera-tors is a g-bessel sequences if and only if the gram matrix associated to its denes a boundedoperator.
