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

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 ...

Scientific Reports, 2020 The most prevalent microdeletion in humans occurs at 22q11.2, a region rich in chromosome-specific low copy repeats (LCR22s). The structure of this region has defied elucidation due to its size, regional complexity, and haplotype diversity, and is not ...

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.

Co-Registration of Optically Sensed Images and Correlation (COSI-Corr): an Operational Methodology for Ground Deformation Measurements [PDF]
, 2008 Recent methodological progress, Co-Registration of Optically Sensed Images and Correlation, outlined here, makes it possible to measure horizontal ground deformation from optical images on an operational basis, using the COSI-Corr software package ...
