Split-Attention Networks with Self-Calibrated Convolution for Moon Impact Crater Detection from Multi-Source Data

open access: yesRemote Sensing, 2021
Impact craters are the most prominent features on the surface of the Moon, Mars, and Mercury. They play an essential role in constructing lunar bases, the dating of Mars and Mercury, and the surface exploration of other celestial bodies.

Slow conduction and gap junction remodeling in murine ventricle after chronic alcohol ingestion

open access: yesJournal of Biomedical Science, 2011
Background Long-term heavy alcohol drinkers are prone to the development of cardiac arrhythmia. To understand the mechanisms, we evaluated the cardiac structural and electrophysiological changes in mice chronically drinking excessive alcohol.

AmpliconReconstructor integrates NGS and optical mapping to resolve the complex structures of focal amplifications

open access: yesNature Communications, 2020
Oncogene amplification, a major driver of cancer pathogenicity, is often mediated through focal amplification of genomic segments. Recent results implicate extrachromosomal DNA (ecDNA) as the primary driver of focal copy number amplification (fCNA ...

Electromechanical optical mapping

open access: yesProgress 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.

Optical map guided genome assembly [PDF]

open access: yesBMC Bioinformatics, 2020
AbstractBackgroundThe long reads produced by third generation sequencing technologies have significantly boosted the results of genome assembly but still, genome-wide assemblies solely based on read data cannot be produced. Thus, for example, optical mapping data has been used to further improve genome assemblies but it has mostly been applied in a ...

Calcium Overload or Underload? The Effects of Doxorubicin on the Calcium Dynamics in Guinea Pig Hearts

open access: yesBiomedicines, 2022
The severe doxorubicin (DOXO) side effect of cardiomyopathy limits it clinical application as an effective anticancer drug. Although Ca2+ overload was postulated as one of the mechanisms for this toxicity, its role was, however, disputable in terms of ...

CCD-based imaging and 3D space--time mapping of terahertz fields via Kerr frequency conversion [PDF]

open access: yes, 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

Optical genome mapping for detection of chromosomal aberrations in prenatal diagnosis

open access: yesActa Obstetricia et Gynecologica Scandinavica, 2023
Introduction Chromosomal aberrations are the most important etiological factors for birth defects. Optical genome mapping is a novel cytogenetic tool for detecting a broad range of chromosomal aberrations in a single assay, but relevant clinical ...

Refinement of optical map assemblies [PDF]

open access: yesBioinformatics, 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

Effects of pacing site and stimulation history on alternans dynamics and the development of complex spatiotemporal patterns in cardiac tissue

open access: yesFrontiers in Physiology, 2013
Alternans of action potential duration has been associated with T-wave alternans and the development of arrhythmias because it produces large gradients of repolarization. However, little is known about alternans dynamics in large mammalian hearts.
