Background: Esophagus cancer, the third most common gastrointestinal cancer overall, demonstrates high incidence in parts of Iran. The counties Iran vary size, shape and population size. aim this study was to account for spatial support with Area-to-Area (ATA) Poisson Kriging increase precision parameter estimates yield correct variance create maps disease rates. Materials Methods: This involved application/ecology methodology, illustrated using esophagus data recorded by Ministry Health...

Analysis of gait dynamics is a noninvasive and totally painless test, it can be an ideal method for the diagnosis neurodegenerative diseases. In this study, based on strength synchronization between strides, we have suggested rating scale Parkinson’s disease (PD). Methods. The sample included 15 persons with PD (age: <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mn>66.8</mn> <mo>±</mo> <mn>10.9</mn> </math> years) 16 healthy id="M2"> <mn>39.3</mn> <mn>18.5</mn> <mtext> </mtext>...

Abstract The aim of the present work is to generalize contraction theory for analysis convergence fractional order systems both continuous-time and discrete-time systems. Contraction a methodology assessing stability trajectories dynamical system with respect one another. result this study generalization Lyapunov matrix equation linear eigenvalue analysis. proposed approach gives necessary sufficient condition exponential global nonlinear examples elucidate that very straightforward exact.

Contraction theory regards the convergence between two arbitrary system trajectories. In this article we have introduced partial contraction as an extension of to analyze coupled identical fractional order systems. It can, also, be applied study synchronization phenomenon in networks various structures and with number We used derive exact global results on antisynchronization
