Acoustic Effects Accurately Predict an Extreme Case of Biological Morphology
(American Physical Society, 2009-07-17)
The biosonar system of bats utilizes physical baffle shapes around the sites of ultrasound emission for diffraction-based beam forming. Among these shapes, some extreme cases have evolved that include a long noseleaf ...
Thermal conductivity and interface thermal conductance of amorphous and crystalline Zr47Cu31Al13Ni9 alloys with a Y2O3 coating
(AIP Publishing, 2009-02-01)
We examine the thermal conductivity k and interface thermal conductance G for amorphous and crystalline Zr47Cu31Al13Ni9 alloys in contact with polycrystalline Y2O3. Using time-domain thermoreflectance, we find k=4.5 W m(-1) ...
The kinetics of analyte capture on nanoscale sensors
(CELL PRESS, 2006-03-01)
This article presents a number of kinetic analyses related to binding processes relevant to capture of target analyte species in nanoscale cantilever-type devices designed to detect small concentrations of biomolecules. ...
Basins of attraction of tapping mode atomic force microscopy with capillary force interactions
(AIP Publishing, 2009-06-01)
We perform a large number of simulations over a wide range of system parameters to approximate the basins of attraction of steady oscillating solutions. We find that the basins of attraction vary as a function of system ...
A piezomagnetoelastic structure for broadband vibration energy harvesting
(AIP Publishing, 2009-06-01)
This letter introduces a piezomagnetoelastic device for substantial enhancement of piezoelectric power generation in vibration energy harvesting. Electromechanical equations describing the nonlinear system are given along ...
Power generation and shunt damping performance of a single crystal lead magnesium niobate-lead zirconate titanate unimorph: Analysis and experiment
(AIP Publishing, 2008-12-01)
This letter investigates the power generation and shunt damping performance of the single crystal piezoelectric ceramic lead magnesium niobate-lead zirconate titanate (PMN-PZT) analytically and experimentally. PMN-PZT is ...
Label-free DNA sequence detection using oligonucleotide functionalized optical fiber
(AIP Publishing, 2006-10-01)
The authors present a label-free method for direct detection of deoxyribonucleic acid (DNA) sequences. The capture DNA is immobilized onto the surface of a silica optical fiber tip by means of the layer-by-layer electrostatic ...
Non-linear, adaptive array processing for acoustic interference suppression
(Acoustical Society of America, 2009-06-01)
A method is introduced where blind source separation of acoustical sources is combined with spatial processing to remove non-Gaussian, broadband interferers from space-time displays such as bearing track recorder displays. ...
Stochastic simulation of enzyme-catalyzed reactions with disparate timescales
(CELL PRESS, 2008-10-01)
Many physiological characteristics of living cells are regulated by protein interaction networks. Because the total numbers of these protein species can be small, molecular noise can have significant effects on the dynamical ...
