Active force generation contributes to the complexity of spontaneous activity and to the response to stretch of murine cardiomyocyte cultures. [PDF]
, 2022 Monolayer cultures of cardiac cells exhibit spontaneous electrical and contractile activity, as in a natural cardiac pacemaker. Beating variability in these preparations recapitulates the power-law behavior of heart rate variability in vivo. However, the

GHz Optical Time-Stretch Microscopy by Compressive Sensing
IEEE Photonics Journal, 2017 Optical time-stretch microscopy has recently attracted intensive attention for its capability of acquiring images at an ultrahigh frame rate. Unfortunately, its achievable frame rate is limited by the requirement of having no overlap between consecutive ...

MAPK activation modulates permeability of isolated rat alveolar epithelial cell monolayers following cyclic stretch. [PDF]
PLoS ONE, 2010 We cultured (5 days) rat alveolar epithelial cells to investigate the role of mitogen-activated protein kinase (MAPk) signaling in ventilator induced epithelial barrier dysfunction. Cells were stretched to a magnitude of 12% or 37% change in surface area

Characterization of critical stretch rate using outwardly propagating spherical flames [PDF]
, 2018 Outwardly propagating spherical flames within a constant volume combustion chamber (CVCC) are studied to analyse the non-linear relationship between flame stretch and flame speed, enabling a critical appraisal of a methodology proposed for characterizing

Context-Aware Image Compression. [PDF]
PLoS ONE, 2016 We describe a physics-based data compression method inspired by the photonic time stretch wherein information-rich portions of the data are dilated in a process that emulates the effect of group velocity dispersion on temporal signals.

Video_2_Ischemia Enhances the Acute Stretch-Induced Increase in Calcium Spark Rate in Ventricular Myocytes.MP4 [PDF]
, 2020 Introduction: In ventricular myocytes, spontaneous release of calcium (Ca2+) from the sarcoplasmic reticulum via ryanodine receptors (“Ca2+ sparks”) is acutely increased by stretch, due to a stretch-induced increase of reactive oxygen species (ROS).

Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner
Journal of Thermal Science and Technology, 2018 Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...
