In this paper, first free parameters are constrained in the description of rational cubic function  to preserve the shape of data that lies above the straight line. Then, rational cubic function is extended to rational bicubic partially blended function (Coons patches). A local positivity preserving scheme is developed for positive data by making… (More)
In this review, we aim to provide clinical insights into the relationship between surgery, general anesthesia (GA), and dementia, particularly Alzheimer's disease (AD). The pathogenesis of AD is complex, involving specific disease-linked proteins (amyloid-beta [Aβ] and tau), inflammation, and neurotransmitter dysregulation. Many points in this complex… (More)
Let G 1 , G 2 , ..., G n be a family of disjoint stars. The tree obtained by joining a new vertex a to one pendant vertex of each star G i is called a banana tree. In this paper we determine the super edge-magic total labelings of the banana trees that have not been covered by the previous results .
OBJECTIVE Psychiatric disorders are common among medical inpatient settings and management of psychiatric disorders can be challenging in this setting. Integrated models of care (IMCs) combining psychiatric and medical specialties within a single service may improve psychiatric and medical outcomes, although evidence for IMCs in medical inpatient settings… (More)
A rational cubic spline  is extended to rational bicu-bic spline. Simple constraints are made on the free parameters in the description of rational bicubic spline to preserve the shape of positive surafac data and to preserve the shape of the data that lie above a plane.
A smooth surface interpolation scheme for positive and convex data has been developed. This scheme has been extended from the rational quadratic spline function of Sarfraz  to a rational bi-quadratic spline function. Simple data dependent constraints are derived on the free parameters in the description of rational bi-quadratic spline function to… (More)
A C1 piecewise rational trigonometric cubic function with four shape parameters has been constructed to address the problem of visualizing positive data. Simple data-dependent constraints on shape parameters are derived to preserve positivity and assure smoothness. The method is then extended to positive surface data by rational trigonometric bicubic… (More)
