Multiscale, structure-based modeling for the elastic mechanical behavior of arterial walls
(2007)
Passive elastic behavior of arterial wall remains difficult to model. Although phenomenological and structural models exist, the question of how the three-dimensional network structure of the collagen in the artery determines ...
Microstructural and morphological effects on the tribological properties of electron enhanced magnetron sputtered hard coatings
(1995)
X-ray diffraction measurements and scanning electron microscopy studies on close to stoichiometric titanium carbonitride [TiCxN(1 _x)] and carbon containing tungsten coatings produced in an electron enhanced unbalanced ...
Effect of inhomogeneities on the fluctuation-induced cusp in the specific heat of high temperature superconductors
(1989)
We consider the effect of inhomogeneities on the electronic specific heat in high temperature superconductors. We find that a modest spread in the transition temperature of the sample can significantly alter the detailed ...
Layered atomic structures of double oxides for low shear strength at high temperatures
(2010)
Double oxide phases combining a transition metal and a noble metal have recently become a subject of investigation as solid lubricant materials for high-temperature tribological applications. Here, we study the changes in ...
Effect of gold and silver nanoislands on the electrochemical properties of carbon nanofoam
(2013)
•Metallic nanoislands coated on the exterior surface of carbon nanofoam.•Their properties are dependent on the type of the metallic nanoisland.•The gold-associated redox reactions enhance their electrochemical performance.
Techniques for Perfusion Imaging with Microbubble Contrast Agents
(2001)
Deals with a study which introduced a common methodology, based directly upon the measured or modeled properties of agent and tissue, whereby Doppler and radio frequency (RF) filters for perfusion imaging can be optimized. ...
Physical system modeling
(2010)
Combining two strategies to improve perfusion and drug delivery in solid tumors
(2013)
Blood perfusion in tumors can be significantly lower than that in the surrounding normal tissue owing to the leakiness and/or compression of tumor blood vessels. Impaired perfusion reduces oxygen supply and results in a ...
Design considerations for nanotherapeutics in oncology
(2015)
Nanotherapeutics have improved the quality of life of cancer patients, primarily by reducing the adverse effects of chemotherapeutic agents, but improvements in overall survival are modest. This is in large part due to the ...
Intelligent drug delivery systems for the treatment of solid tumors
(2016)
The rationale for the use of nanoparticle formulations to treat cancer is based on the ability of these particles to facilitate selective delivery of drugs to the tumor site, reducing adverse effects and improving therapeutic ...
