CCD-based imaging and 3D space--time mapping of terahertz fields via Kerr frequency conversion [PDF]
, 2013 We investigate the spatially and temporally resolved four-wave mixing of terahertz (THz) fields and optical pulses in large-bandgap dielectrics, such as diamond. We show that it is possible to perform beam profiling and space–time resolved mapping of THz

Electromechanical optical mapping
Progress in Biophysics and Molecular Biology, 2017 Optical mapping is a widely used imaging technique for investigating cardiac electrophysiology in intact, Langendorff-perfused hearts. Mechanical contraction of cardiac tissue, however, may result in severe motion artifacts and significant distortion of the fluorescence signals.

Image processing for optical mapping [PDF]
GigaScience, 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 ...

Optogenetic Control of Human Induced Pluripotent Stem Cell‐Derived Cardiac Tissue Models
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022 Background Optogenetics, using light‐sensitive proteins, emerged as a unique experimental paradigm to modulate cardiac excitability. We aimed to develop high‐resolution optogenetic approaches to modulate electrical activity in 2‐ and 3‐dimensional ...

Refinement of optical map assemblies [PDF]
Bioinformatics, 2006 Abstract Motivation: Genomic mutations and variations provide insightful information about the functionality of sequence elements and their association with human diseases. Traditionally, variations are identified through analysis of short DNA sequences, usually shorter than 1000 bp per fragment. Optical maps provide both faster and more

Optical Mapping of Cardiac Electromechanics [PDF]
Biophysical Journal, 2016 Cardiac biophysics rests on three fundamental pillars: energy production, electrical excitation, and mechanical work. Studies of cardiac metabolism, bioelectricity, and biomechanics have been very productive at all levels of reduced complexity, but especially at the levels of tissue, cell, and molecule.

Probing the Electrophysiology of the Developing Heart
Journal 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.
