Background: Katz Index is a well-known index for assessing basic activities of daily living. The aim was to determine validity and reliability of the Katz Index in Iranian patients with acute stroke. Methods: Eighty-seven patients (56 male, 31 female) with acute stroke (1-30 days post-stroke) participated in this psychometric properties study. Interval time for retest was 14 days. All partic...

b a ckground:  nutrition status is an important constituent of health in an elderly and  evaluation  of  these  groups  are  necessary  for  development  of  treatment protocols. the study aimed to estimate the prevalence of malnutrition with mini nutritional assessment (mna)  tool  in  the  elderly living in  nursing homes.  in addition, the association of mna results and functional status was...

We study the causal impact of network centrality on educational outcomes using field experiments in primary schools in Bangladesh. After obtaining information on friendship networks, we randomly allocate students into groups and give them individual and group assignments. We find that groups that perform best are those whose members have high Katz-Bonacich and key-player centralities. Leaders a...

Three-dimensional icosahedral random tilings are studied in the semi-entropic model. We introduce a global energy measure defined by the variance of the quasi-lattice points in orthogonal space. The specific heat shows a pronounced Schottky type anomaly, but it does not diverge with sample size. The flip susceptibility as defined by Dotera and Steinhardt [Phys. Rev. Lett. 72, 1670 (1994)] diver...

We consider shock probes in a one-dimensional driven diffusive medium with nearest-neighbor Ising interaction (KLS model). Earlier studies based on an approximate mapping of the present system to an effective zero-range process concluded that the exponents characterizing the decays of several static and dynamical correlation functions of the probes depend continuously on the strength of the Isi...

Motivated by definitions in mixed Hodge theory, we define the weight filtration and monodromy on combinatorial intersection cohomology of a fan. These filtrations give natural definition multivariable invariants subdivisions polytopes, lattice polytopes fans, namely h-polynomial, refined limit h⁎-polynomial, cd-index, defined Katz–Stapledon Dornian–Katz–Tsang. Previously, only h⁎-polynomial had...

WHY: Normal aging changes and health problems frequently show themselves as declines in the functional status of older adults. Decline may place the older adult on a spiral of iatrogenesis leading to further health problems. One of the best ways to evaluate the health status of older adults is through functional assessment which provides objective data that may indicate future decline or improv...
