An important question of ongoing interest for linear time-delay systems is to provide conditions on its parameters guaranteeing exponential stability solutions. Recent works have explored spectral techniques show that, some low-order delay-differential equations retarded type, values maximal multiplicity are dominant, and hence determine the asymptotic behavior system, a property known as multi...

Celiac disease (CED) is immune-mediated enteropathy caused by gluten intolerance affecting genetically predisposed individuals. CED may exert a number of various symptoms, including extra intestinal manifestations. Neurological symptoms can be the first sign of gluten intolerance. However, affected autonomic nervous system (ANS) activity may be linked to other symptoms. We evaluated the frequen...

Background The increase of sanitary costs related to poststroke rehabilitation requires new sustainable and cost-effective strategies for promoting autonomous and dehospitalized motor training. In the Riprendo@Home and Future Home for Future Communities research projects, the promising approach of introducing low-cost technologies that promote home rehabilitation is exploited. In order to provi...

The patient was a 62-years-old man that known case of hypertension for 15 years and had history cerebrovascular accident 10 days ago admitted to our hospital due chest pain dyspnea, after evaluation workups, coronary angiography revealed an absence left circumflex artery with right dominancy.

introduction: until now, many models have been presented for optical study of the human eye. in recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. material and methods: in this article, some of these models are considered. they incl...

background: isolated right bundle branch block (rbbb) is a common finding in the general population. the atrioventricular node (avn) artery contributes to the blood supply of the right bundle branch. our hypothesis was that the anatomy of the avn artery and the pattern of dominancy differ between subjects with and without rbbb. methods: w e retrospectively studied the coronary angiography of 92...

A species-specific latitudinal distribution of soybean rhizobia has been reported; Bradyrhizobium japonicum and B. elkanii dominate in nodules northern southern areas, respectively. The aim this study was to elucidate whether temperature-dependent proliferation soil or infection is more reliable for determining the characteristic soybean-nodulating under local climate conditions. Three location...
