Multiclass semantic segmentation and quantification of traumatic brain injury lesions on head CT using deep learning: an algorithm development and multicentre validation study
(Elsevier, 2020-05)
Background. CT is the most common imaging modality in traumatic brain injury (TBI). However, its conventional use requires expert clinical interpretation and does not provide detailed quantitative outputs, which may have ...
The segmentation of the argentine education system: evidence from PISA 2009
(Euro-American Association of Economic Development, 2011-07)
For decades, one of the main goals for policy makers throughout the world has been to provide equal educational opportunities. Nevertheless, many countries still face great challenges in this respect, especially considering ...
Steric and electronic effects on mesophase stability of segmented liquid crystalline polymers with arylazomethine pendant groups
(Springer, 2000-09)
The synthesis and thermotropic behavior are reported for a series of polyesters, 1, and its model compounds, 2, which bear a N-arylazomethine pendant group with para-substituents in order to evaluate electronic and steric ...
Water content effect on the chromatic attributes of dehydrated strawberries during storage, as evaluated by image analysis
(Elsevier Science, 2013-07)
The changes of chromatic attributes due to different hydration degree, anthocyanins degradation and browning development were studied in dehydrated strawberries. Strawberry slices were freeze-dried, equilibrated at different ...
Signal density of left ventricular myocardial segments and impact of beam hardening artifact: Implications for myocardial perfusion assessment by multidetector CT coronary angiography
(Springer, 2010-03)
We sought to explore the normal myocardial signal density (SD) levels during multidetector computed tomography coronary angiography (MDCT-CA) acquisitions and evaluated the impact of beam hardening artifacts. Background: ...
A compact high-resolution spectrometer based on a segmented conical crystal analyzer
(American Institute of Physics, 2020-04)
In this work, the design, fabrication, and evaluation of a compact, one-shot spectrometer based on a segmented conically bent crystal analyzer are described. The system is a “one-shot” wavelength dispersive spectrometer, ...
Automatic quantification of the LV function and mass: A deep learning approach for cardiovascular MRI
(Elsevier, 2019-02)
Objective: This paper proposes a novel approach for automatic left ventricle (LV) quantification using convolutional neural networks (CNN). Methods: The general framework consists of one CNN for detecting the LV, and another ...
Semi-automatized segmentation method using image-based flow cytometry to study sperm physiology: The case of capacitation-induced tyrosine phosphorylation
(Oxford University Press, 2018-02)
Is image-based flow cytometry a useful tool to study intracellular events in human sperm such as protein tyrosine phosphorylation or signaling processes? Image-based flow cytometry is a powerful tool to study intracellular ...
Fluorescent amorphous distyrylnaphthalene-based polymers: Synthesis, characterization and thin-film nanomolar sensing of nitroaromatics in water
(Multidisciplinary Digital Publishing Institute, 2018-12)
Two new fluorescent segmented conjugated polymers with either 1,4- or 2,6-distyrylnaphthalene chromophores and their model compounds were synthesized and the chemosensing abilities of the polymeric thin films to detect ...
Photoactive thin films of terphenylene-based amorphous polymers: Synthesis, electrooptical properties, and role of photoquenching and inner filter effects in the chemosensing of nitroaromatics
(Elsevier Science Sa, 2019-11)
New photoactive segmented conjugated polymers with terphenylene chromophores were synthesized, and the chemosensing abilities to detect nitroaromatics compounds (NACs) of the polymeric thin films were evaluated in aqueous ...
