OBJECTIVES The purpose of this study was to evaluate predictors of change in household size and institutionalization in late life. METHODS The Duke Established Populations for Epidemiologic Studies of the Elderly cohort (n = 3730) was assessed annually (1986-1996). Independent variables included home ownership, income, cognitive and functional ability, chronic illness, mood, household size, s...

An expansion of the energy functional in terms of the total number of electrons and the normal coordinates within the canonical ensemble is presented. A comparison of this expansion with the expansion of the energy in terms of the total number of electrons and the external potential leads to new relations among common density functional reactivity descriptors. The formulas obtained provide expl...

The incomplete gamma function expansion for the perturbed Epstein zeta function is known as Ewald expansion. In this paper we state a special case of the main formula in Kanemitsu and Tsukada (Contributions to the theory of zeta-functions: the modular relation supremacy. World Scientific, Singapore, 2014) whose specifications will give Ewald expansions in the H-function hierarchy. An Ewald expa...

The spin glass behavior near zero temperature is a complicated matter. To get an easier access to the spin glass order parameter Q(x) and, at the same time, keep track of Qab, its matrix aspect, and hence of the Hessian controlling stability, we investigate an expansion of the free energy functional around its “spherical” approximation. This expansion is obtained by introducing a constraint fie...

Damage or deprivation of a localized region of the skin surface has been shown to induce a selective expansion of adjacent skin surface representations in the adult somatosensory cortex. Here, we use repeated optical imaging in conjunction with single unit recordings to assess the plasticity of a single whisker's functional representation in the adult rat. We observed a large-scale expansion of...

In this paper, functional neuron structure will be expanded and deformed in the functional networks, then the expansion type functional neuron network model is obtained, and the pinv Moore-Penrose of matrix is employed, the optimal value of the functional parameters in the functional networks can be rapidly and accurately determined directly. Finally simulation experiments show that the propose...

We study the 3d Ising universality class using the functional renormalisation group. With the help of background fields and a derivative expansion up to fourth order we compute the leading index, the subleading symmetric and anti-symmetric corrections to scaling, the anomalous dimension, the scaling solution, and the eigenperturbations at criticality. We also study the cross-correlations of sca...

articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...

Functional epistemology is about ways to access functional objects by using varieties of methods and procedures. Not all such means are equally capable reproducing these functions in the desired consistency resolution. Dyson’s argument against perturbative expansion quantum field theoretic terms, a radical form (never pursued Dyson), an example taken as ontology.
