Implications of ab initio energetics on the thermodynamics of Fe-Cr alloys
(AIP Publishing, 2006-09-01)
The authors analyze the implications of the recently reported results of ab initio calculations of formation energies of the Fe-Cr alloy. The formation energies show a change in sign from negative to positive as Cr composition ...
Molecular simulation study of structural and dynamic properties of mixed DPPC/DPPE bilayers
(CELL PRESS, 2006-06-01)
Molecular dynamics simulations have been used to study structural and dynamic properties of fully hydrated mixed 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE) ...
A computational study of nucleosomal DNA flexibility
(CELL PRESS, 2006-12-01)
Molecular dynamics simulations of the nucleosome core particle and its isolated DNA free in solution are reported. The simulations are based on the implicit solvent methodology and provide insights into the nature of ...
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. ...
The Effects of Text Drawing Styles, Background Textures, and Natural Lighting on Text Legibility in Outdoor Augmented Reality
(MIT Press, 2006-02-01)
A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in ...
Maximum power of quantum dot laser versus internal loss
(AIP Publishing, 2006-02-01)
Internal loss, which increases with the carrier density outside the active region, causes a rollover of the light-current curve and strongly limits the output power of a diode laser with a single layer of quantum dots. The ...
Surface-Mount Sapphire Interferometric Temperature Sensor
(Optical Society of America, 2006-02-01)
A fiber-optic high-temperature sensor is demonstrated by bonding a 45 degrees-polished single-crystal sapphire fiber on the surface of a sapphire wafer, whose optical thickness is temperature dependent and measured by ...
Micro-Air-Gap Based Intrinsic Fabry-Perot Interferometric Fiber-Optic Sensor
(Optical Society of America, 2006-05-01)
A simple intrinsic Fabry-Perot interferometric (IFPI) sensor is developed. The sensor is fabricated by two micro air gaps as reflective mirrors in a fiber to form a Fabry-Perot cavity. Theoretical and experimental studies ...
Implementation Of A Loss-Compensated Recirculating Delayed Self-Heterodyne Interferometer For Ultranarrow Laser Linewidth Measurement
(Optical Society of America, 2006-12-01)
Ultranarrow laser linewidth measurement using an optimized loss-compensated recirculating delayed self-heterodyne interferometer is described. An experimental setup is constructed to measure subkilohertz laser linewidths. ...
Modification Of Spontaneous Emission in Bragg Onion Resonators
(Optical Society of America, 2006-03-01)
We formulated an analytical model and analyzed the modification of spontaneous emission in Bragg onion resonators. We consider both the case of a single light emitter and a uniformly distributed ensemble of light emitters ...
