Mathematical Modeling for the Pathogenesis of Alzheimer's Disease
Despite extensive research, the pathogenesis of neurodegenerative Alzheimer's disease (AD) still eludes our comprehension. This is largely due to complex and dynamic cross-talks that occur among multiple cell types throughout ...
The Effects of Higher Levels of Immersion on Procedure Memorization Performance and Implications for Educational Virtual Environments
(MIT Press, 2010-12-01)
Researchers have proposed that immersion could have advantages for tasks involving abstract mental activities, such as conceptual learning; however, there are few empirical results that support this idea. We hypothesized ...
Towards the creation of decellularized organ constructs using irreversible electroporation and active mechanical perfusion
(Biomed Central Ltd, 2010-12-10)
Applications and Security of Next-Generation, User-Centric Wireless Systems
Pervasive wireless systems have significantly improved end-users quality of life. As manufacturing costs decrease, communications bandwidth increases, and contextual information is made more readily available, the role of ...
Effect of intensive and extensive loss factors on the dynamic response of magnetoelectric laminates
(AIP Publishing, 2010-11-01)
We report the correlation between intensive and extensive losses in piezoelectric materials with the frequency dependent response of layered magnetoelectric (ME) composites. Three different piezoelectric compositions were ...
Metal-ceramic laminate composite magnetoelectric gradiometer
(AIP Publishing, 2010-03-01)
Gradiometer resembles in functionality a magnetic field sensor where it measures the magnetic field gradient and its sensitivity is determined by the ability to quantify differential voltage change with respect to a reference ...
Fermi level unpinning of GaSb (100) using plasma enhanced atomic layer deposition of Al2O3
(AIP Publishing, 2010-10-01)
N-type and p-type GaSb metal-oxide-semiconductor capacitors (MOSCAPs) with atomic-layer-deposited (ALD) and plasma-enhanced-ALD (PEALD) Al2O3 dielectrics are studied to identify the optimum surface preparation and oxide ...
Resonant manifestation of intrinsic nonlinearity within electroelastic micropower generators
(AIP Publishing, 2010-12-01)
This letter investigates the nonlinear response of a bimorph energy harvester comprised of lead zirconate titanate (PZT-5A) laminates. For near resonant excitations, we demonstrate significant intrinsic nonlinear behavior ...
Spherical cap harmonic analysis of Super Dual Auroral Radar Network (SuperDARN) observations for generating maps of ionospheric convection
(American Geophysical Union, 2010-07-01)
A spherical cap harmonic analysis (SCHA) technique is introduced for mapping the 2-D high-latitude ionospheric convection pattern based on Super Dual Auroral Radar Network (SuperDARN) velocity measurements. The current ...
Dielectric and ferroelectric response of compositionally graded bilayer and trilayer composites of BaTiO3 and 0.975BaTiO(3) 0.025Ba(Cu1/3Nb2/3)O-3
(American Institute of Physics, 2010-12-15)
In this paper, we report the dielectric and ferroelectric response of compositionally graded bilayer and trilayer composites consisting of BaTiO3 (BT) and 0.975BaTiO(3)-0.025Ba(Cu1/3Nb2/3)O-3 (BTBCN). Two types of graded ...
