Osteonecrosis of the Femoral Head: Core Decompression Systems.

Osteonecrosis of the femoral head (ONFH) is a chronic progressive debilitating disease that often affects young and active patients. It results from vascular interruption to the femoral head and can be caused by trauma, chronic corticosteroid use, chronic alcoholism, and coagulopathies. Treatment includes core decompression, a surgical procedure that may help delay or forestall disease progression if performed at the early stages of the disease.

Relativistic bound state solutions and quantum information theory in D dimensions under exponential-type plus Yukawa potentials.

The bound-state solution of the radial Klein-Gordon equation has been obtained under the interaction of an exponential-type and Yukawa potential functions. The Greene-Aldrich approximation has been used to overcome the centrifugal barrier and enable the analytical solutions of the energy and wave functions in closed form. The momentum space wave function in D dimensions has been constructed using the Fourier transform.

Non-relativistic energy equations for diatomic molecules constrained in a deformed hyperbolic potential function.

Context: In this paper, the approximate analytical energy equations for the deformed hyperbolic potential have been obtained for arbitrary parameters of the potential. The potential function was transformed to a molecular potential by subjecting it to the Varshni conditions which allows for the determination of the energy levels of diatomic molecules. The molecular vibrational energy spectra for [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] diatomic molecules were obtained and found to match with the results obtained with another analytical approach, potential functions, and experimental data.
