A method to identify the difference in kinematic behavior of human model lower extremities with respect to muscle activation during crash impact
(Springer Netherlands, 2019-05-17)The main objective of this study is to develop a computational human musculoskeletal model, used to investigate the change in the kinematic behavior of the model’s lower extremities under the influence of activated (active) ... -
In situ fixation and subsequent collection of cultured endothelial cells in a shear flow
(Elsevier B.V., 2019-05-03)In situ fixation of adherent cells is a necessary process for downstream assays. Current methods to dissociate adherent endothelial cells require the use of a cell scraper that may introduce variability in nuclear morphology. ... -
Biomedical imaging application of open-circuit resonators
(Wichita State University, 2019-04-26)INTRODUCTION: While modern medical imaging technology like computed tomography (CT) and magnetic resonance imaging (MRI) can now reproduce the anatomy of the human body with astounding detail, there remains a need for new ... -
Design and development of a smart wheelchair-mounted robotic exoskeleton for people with reduced upper limb movements
(Wichita State University, 2019-04-26)INTRODUCTION: Cerebral Palsy, Duchenne Muscular Dystrophy, and stroke not only often impair lower extremities, leading to reliance on wheelchairs, but also upper extremity mobility for such patients, severely limiting their ... -
Shoulder joint clearance detection for astronaut space suits using wearable electromagnetic resonant spiral proximity
(Wichita State University, 2019-04-26)INTRODUCTION: Shoulder joint injury is a common musculoskeletal injury that occurs during astronaut training while they are wearing the space suit. There is restricted mobility around the shoulder joint due to the rigid ... -
Nuclear morphology changes in response to variations in fluid shear stress
(Wichita State University, 2019-04-26)INTRODUCTION: Recent studies in mechanogenomics have identified the nucleus as a mechanosensitive organelle that may be responsible for the regulation of cellular phenotype. The emerging field of mechanogenomics seeks to ... -
Radiation tolerance of nanopore sequencing technology for life detection on Mars and Europa
(NATURE PUBLISHING GROUP, 2019-03-29)The search for life beyond Earth is a key motivator in space exploration. Informational polymers, like DNA and RNA, are key biosignatures for life as we know it. The MinION is a miniature DNA sequencer based on versatile ... -
Extracting motor imagery features to control two robotic hands
(IEEE, 2019-02-14)Brain-Machine Interface (BMI) technology has the potential to restore physical movement of the arm or leg by acquiring electroencephalogram (EEG) signals from the human brain, detecting changes associated with a human arm ... -
Evolution of stability/flexibility relationships in beta-lactamase
(Cell Press, 2019-02-15)We have curated over 100 structures of class A beta-lactamase proteins, a family of enzymes that is responsible for a considerable percentage of multidrug antibiotic resistance in bacteria. Our dataset includes three ... -
Characterizing dynamical differences between TEM-1 and TEM-52 beta-lactamases
(Cell Press, 2019-02-15)Beta-lactamase, produced in bacteria, defends against beta-lactam antibiotics such as penicillin and cephalosporins by hydrolyzing the beta-lactam ring. This is a primary cause of antibiotic resistance to beta-lactam ... -
Material characterization and bioanalysis of hybrid scaffolds of carbon nanomaterial and polymer nanofibers
(ACS, 2019-03-08)The interconnected porous structures that mimic the extracellular matrix support cell growth in tissue engineering. Nanofibers generated by electrospinning can act as a vehicle for therapeutic cell delivery to a neural ... -
Ultrahigh conductivity and superior interfacial adhesion of a nanostructured, photonic-sintered copper membrane for printed flexible hybrid electronics
(American Chemical Society, 2018-11-19)Inkjet-printed electronics using metal particles typically lack electrical conductivity and interfacial adhesion with an underlying substrate. To address the inherent issues of printed materials, this Research Article ... -
Migration through a small pore disrupts inactive chromatin organization in neutrophil-like cells
(BioMed Central Ltd., 2018-11-26)Background. Mammalian cells are flexible and can rapidly change shape when they contract, adhere, or migrate. The nucleus must be stiff enough to withstand cytoskeletal forces, but flexible enough to remodel as the cell ... -
Passive self resonant skin patch sensor to monitor cardiac intraventricular stroke volume using electromagnetic properties of blood
(IEEE, 2018-09-26)This paper focuses on the development of a passive, lightweight skin patch sensor that can measure fluid volume changes in the heart in a non-invasive, point-of-care setting. The wearable sensor is an electromagnetic, ... -
The effects of a fatiguing lifting task on postural sway among males and females
(Elsevier, 2018-06)Lifting and falls comprise a large proportion of work related injuries. Repetitive lifting to the point of fatigue can affect postural sway, which is associated with fall risk. To investigate the effects of lifting and ... -
Non-invasive electromagnetic skin patch sensor to measure intracranial fluid–volume shifts
