(Biomedical Engineering, 2014-03-10)The quantification of any improvements in the use of a paretic arm after children with cerebral palsy (CP) undergo rehabilitation is currently done by occupational therapists who administer a series of manual ability tests ... -
Quantification and identification of neuro-electrophysiological markers and brain network for biomedical applications
(2023-08-23)Electroencephalogram (EEG) can detect and monitor neuro-electrophysiological signals in the human brain, including assessing brain function in newborns at risk of neurological injury and healthy adults undergoing intervention ... -
Quantification and normalization of noise variance with sparsity regularization to enhance diffuse optical tomography
(OSA PublishingDepartment of Bioengineering, The University of Texas at Arlington, 2015-08-01)Conventional reconstruction of diffuse optical tomography (DOT) is based on the Tikhonov regularization and the white Gaussian noise assumption. Consequently, the reconstructed DOT images usually have a low spatial ... -

Quantification of Nocturnal Blood Pressure Oscillations in Obstructive Sleep Apnea Patients
(2020-06-05)An approach to quantifying and analysis of nocturnal blood pressure (BP) variations that are elicited by sleep-disordered breathing (SDB) is presented. A sample-by-sample aggregation of the dynamic BP variations during ... -
Quantitative Variation Of Blood Pressure Dynamics During Sleep Apnea
(Biomedical Engineering, 2010-11-01)Sleep Apnea is one of the major sleep disorders characterized by complete cessation or decline in breathing for about 10s or more during sleep, thereby adversely affecting the quality of sleep. Studies show that about 6 % ... -
RATIONAL DESIGN AND SYNTHESIS OF BIODEGRADABLE POLYURETHANE BASED BIOMATERIALS
(2018-12-04)Biodegradable polyurethanes have been applied in biomedical field since 1960s. In recent years, biodegradable polyurethanes have been widely investigated for tissue repair and regeneration because of their good mechanical ... -
Real-time detection of implant-associated neutrophil responses using a formyl peptide receptor-targeting NIR nanoprobe
(Dove pressDepartment of Bioengineering, The University of Texas at Arlington, 2012-04-19)Neutrophils play an important role in implant-mediated inflammation and infection. Unfortunately, current methods which monitor neutrophil activity, including enzyme measurements and histological evaluation, require many ... -
