Use of distributed computing in derivative pricing
(2009)
- article
Monte Carlo option pricing algorithms are well suited to distributed computing because simulations can be run on different computational units with no need for communication between these tasks. In this paper we investigate ...
Calculation of the electrostatic potential of lipid bilayers from molecular dynamics simulations: Methodological issues
(2009)
- article
The electrostatic properties of lipid membranes are of profound importance as they are directly associated with membrane potential and, consequently, with numerous membrane-mediated biological phenomena. Here we address a ...
Systematic coarse graining from structure using internal states: Application to phospholipid/cholesterol bilayer
(2009)
- article
We present a two-dimensional coarse-grained (CG) model for a lipid membrane composed of phospholipids and cholesterol. The effective CG interactions are determined using radial distribution functions (RDFs) from atom-scale ...
Strong enhancement of second-harmonic generation in all-dielectric resonant waveguide grating
(2007)
- article
The authors demonstrate that a dielectric resonant waveguide grating can enhance optical second-harmonic generation by a factor of 550 compared to a similar flat surface. Their structure, which consists of purely dielectric ...
Conformational analysis of lipid molecules by self-organizing maps
(2007)
- article
The authors have studied the use of the self-organizing map (SOM) in the analysis of lipid conformations produced by atomic-scale molecular dynamics simulations. First, focusing on the methodological aspects, they have ...
Programmable and scalable architecture for graphics processing units
(2009)
- article
Graphics processing is an application area with high level of parallelism at the data level and at the task level. Therefore, graphics processing units (GPU) are often implemented as multiprocessing systems with high ...
Assessing the nature of lipid raft membranes
(2007)
- article
The paradigm of biological membranes has recently gone through a major update. Instead of being fluid and homogeneous, recent studies suggest that membranes are characterized by transient domains with varying fluidity. In ...
Multiple gate delay tracking structures for GNSS signals and their evaluation with Simulink, SystemC, and VHDL
(2008)
- article
Accurate delay tracking in multipath environments is one of the prerequisites of modern GNSS receivers. Several solutions have been proposed in the literature, both feedback and feedforward. However, this topic is still ...
High-power disk lasers based on dilute nitride heterostructures
(2009)
- review
We report the development of InGaAsN-based gain mirrors for high-power optically pumped semiconductor disk lasers with direct emission at wavelengths around 1180 nm. The gain mirrors were fabricated by molecular beam ...
