Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

Two Nonisospectral Integrable Hierarchies and its Integrable Coupling

International Journal of Theoretical Physics, 2020
The authors introduce a complex Lie algebra and construct two nonisospectral integrable hierarchies based on it. Then the Hamiltonian structure and the expanding nonisospectral integrable hierarchies are investigated.

INTEGRABLE HIERARCHIES FROM BRST COHOMOLOGY

Modern Physics Letters A, 2005
We demonstrate that the Hamiltonian structure and the integrability of a system of evolution equations can be formulated in terms of a classical field theory using BRST and anti-BRST symmetries. We derive the field theory action and explicitly generate the integrable hierarchy associated to a bi-Hamiltonian system based on cohomological arguments and ...

NEW INTEGRABLE LATTICE HIERARCHY AND ITS INTEGRABLE COUPLING

International Journal of Modern Physics B, 2009
New hierarchy of Liouville integrable lattice equation and their Hamiltonian structure are generated by use of the Tu model. Then, integrable couplings of the obtained system is worked out by the extending spectral problem.

A NEW EXPANDING INTEGRABLE HIERARCHY OF KAUP–NEWELL HIERARCHY

Modern Physics Letters B, 2006
A higher loop algebra is constructed which is devoted to establish an isospectral Lax pair. Integrable coupling of the well-known Kaup–Newell hierarchy is obtained by using a relation of direct sum between two sub-algebras. As in the reduction case, an integrable coupling of a generalized MKdV equation is presented. The approach presented in the paper
