There are many potential benefits to ablation of atrial fibrillation (AF), but the impact on functional status has not yet been thoroughly investigated. Activity sensors in implanted cardiac devices provide a novel opportunity for an investigation. In addition, there may be difference between patients with paroxysmal or persistent AF. The purpose this study was examine AF objective behavioral d...

The conservation equation for a monochromatic field with arbitrary polarization propagating in an inhomogeneous transparent medium is expressed in terms of amplitude and phase variables. The expressions obtained for linearly polarized fields are compared with the results obtained in the eikonal approximation. The electric field wave equation is written in terms of intensity and phase variables....

Physical optics, or Fresnel–Kirchhoff theory, is often used for studies of particular problems in terrestrial radio-wave propagation. With efficient techniques of numerical integration, it can also be used effectively for routine predictions and for designing terrestrial wireless systems. A computer program of this type has been in use for several years. It is most useful in situations in which...

Standard and nerve-intact grafts of the extensor digitorum longus (EDL) muscles of rats do not fully recover control values for maximum tetanic tension (Po). We compared the physiologic properties of motor units from standard and nerve-intact EDL grafts of rats with those of control EDL muscles. Standard grafts were completely removed and replaced in their original site. For nerve-intact grafts...

objective(s)cpg oligodeoxynucleotides (cpg odns) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. due to susceptibility of phosphodiester cpg odns (po cpg) to nuclease degradation, nuclease-resistant phosphorothioate cpg odns (ps cpg) were currently utilized in an in vivo model. in this study, according to some recently reported drawbacks with ps ...

in (golchin a. and rezaei p., subpullbacks and flatness properties of s-posets. comm. algebra. 37: 1995-2007 (2009)) study was initiated of flatness properties of right -posets  over a pomonoid  that can be described by surjectivity of  corresponding to certain (sub)pullback diagrams and new properties such as  and  were discovered. in this article first of all we describe po-flatness propertie...

PURPOSE To evaluate the effects of a structured hand cycle training programme on physical capacity in subjects with spinal cord injury (SCI) during clinical rehabilitation. METHOD Twenty subjects with SCI who followed hand cycle training were compared with matched control subjects from a Dutch longitudinal cohort study, who received usual care. Primary outcomes of physical capacity were peak ...

The power of the SLC linac, as a source for both elec-.trons &d po&rons, was demonstrated in the conceptual design report-(CDR) [l] (also see Table 1). A brief overview of the whole injection system is given in ReferenceJZ}. Figure 1 is a schematic of the system. One can divide the injection system into two main parts. The first is the extraction of e-e+ from the linac and their bypass lines le...

The physical mechanism of phenomenon is explained as a result of inequality of forward and reversed processes in optics. The importance of experimental study of its invariance relation is discussed. There is rather usual situation in nonlinear optics when a phenomenon has mathematical description, but clear explanation of its physical mechanism is absent. Clear physical sense appears if we use ...
