Address correspondence to [email protected] ABSTRACT The output of an ultrasonic wave-driven nanogenerator (NG) has been found to depend on the excitation conditions and geometry. Incidence angle tests indicate that the effective area of an NG determines the amount of power that can be generated. The output power of an NG is also directly related to its distance from the ultrasonic source. A si...

Posttraumatic stress disorder is characterized by the failure of the acute fear response to diminish after exposure to a lifethreatening traumatic event. Risk factors for PTSD include sex (female), education (less), and familial and genetic factors, as well as factors pertaining to the type and severity of trauma(s) experienced by the individual over time (including childhood maltreatment). The...

A parallel version of a nite diierence discretization of PDEs on sparse grids is proposed. Sparse grids or hyperbolic crosspoints can be used for the eecient representation of solutions of a boundary value problem, especially in high dimensions , because the number of grid points depends only weakly on the dimension. So far only thècombination' technique for regular sparse grids was available o...

Toxoplasma gondii is one of the most prevalent parasitic infections in world. Rh, NED and Me49 are of the most prevalent clonal types of the parasite isolated till now. Differences in pathogenicity and virulence of different types have been investigated in different studies. No controlled study was performed to compare the ability of different types to initiate humoral immune response. We inves...

In a fuzzy metric space (X;M; *), where * is a continuous t-norm,a locally fuzzy contraction mapping is de ned. It is proved that any locally fuzzy contraction mapping is a global fuzzy contractive. Also, if f satis es the locally fuzzy contractivity condition then it satis es the global fuzzy contrac-tivity condition.
