Probing the Electrophysiology of the Developing Heart

open access: yesJournal of Cardiovascular Development and Disease, 2016
Many diseases that result in dysfunction and dysmorphology of the heart originate in the embryo. However, the embryonic heart presents a challenging subject for study: especially challenging is its electrophysiology.

Cross-correlation cosmography with HI intensity mapping [PDF]

open access: yes, 2015
The cross-correlation of a foreground density field with two different background convergence fields can be used to measure cosmographic distance ratios and constrain dark energy parameters.

Stellar Intensity Interferometry: Astrophysical targets for sub-milliarcsecond imaging [PDF]

open access: yes, 2010
Intensity interferometry permits very long optical baselines and the observation of sub-milliarcsecond structures. Using planned kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial ...

Image processing for optical mapping [PDF]

open access: yesGigaScience, 2015
Optical Mapping is an established single-molecule, whole-genome analysis system, which has been used to gain a comprehensive understanding of genomic structure and to study structural variation of complex genomes. A critical component of Optical Mapping system is the image processing module, which extracts single molecule restriction maps from image ...

General Hubbard model for strongly interacting fermions in an optical lattice and its phase detection [PDF]

open access: yes, 2007
Based on consideration of the system symmetry and its Hilbert space, we show that strongly interacting fermions in an optical lattice or superlattice can be generically described by a lattice resonance Hamiltonian.

Canonical Transformation Approach to the Ultrafast Non-linear Optical Dynamics of Semiconductors

open access: yes, 1999
We develop a theory describing the effects of many-particle Coulomb correlations on the coherent ultrafast nonlinear optical response of semiconductors and metals.

Far-field mapping of the longitudinal magnetic and electric optical fields [PDF]

open access: yes, 2013
In this letter, we demonstrate the experimental mapping of the longitudinal magnetic and electric optical fields with a standard scanning microscope that involves a high numerical aperture far-field objective.

Design and analysis of a general data evaluation system based on social networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
A social network is a social structure with a set of social actors and other social interactions between actors. The social network supports a set of methods to explain the structure of whole social entities as well as a variety of theories in these ...

HST Observations of GRO J1655-40 in Outburst [PDF]

open access: yes, 1998
We examine the results of a coordinated HST-RXTE-CGRO campaign to study the microquasar GRO J1655-40 during its 1996-7 outburst, focusing on interpretation of the overall anti-correlation seen between optical and X-ray fluxes during the early months of ...

Ectopic foci do not co‐locate with ventricular epicardial stretch during early acute regional ischemia in isolated pig hearts

open access: yesPhysiological Reports, 2022
Ectopic activation during early acute regional ischemia may initiate fatal reentrant arrhythmias. However, the origin of this ectopy remains poorly understood.
