International Conference of the IEEE Engineerin... 2014:1394 (2014) PMID 25570228An element design for receive array coils that decouples from the transmit coil without external active detuning is presented for magnetic resonance imaging (MRI) of mice. The array element uses a crisscrossed geometry on the return paths to reduce the current induced by the transmit coil. Witho...
International Conference of the IEEE Engineerin... 2014:1517 (2014) PMID 25570258Schizophrenia, schizoaffective and bipolar disorders share some common symptoms. However, the biomarkers underlying those disorders remain unclear. In fact, there is still controversy about the schizoaffective disorder with respect to its validity of independent category and its relationship wit...
International Conference of the IEEE Engineerin... 2014:1599 (2014) PMID 25570278Adapting limb mechanics in a task and environment dependent manner is one component of human motor control. Joint mechanics have been extensively studied under static postural conditions, but less so under time-varying movement conditions. The limited studies that have investigated joint mechani...
International Conference of the IEEE Engineerin... 2014:4932 (2014) PMID 25571098Analysis of the dynamics (non-stationarity) of functional connectivity patterns has recently received a lot of attention in the neuroimaging community. Most analysis has been using functional magnetic resonance imaging (fMRI), partly due to the inherent technical complexity of the electro- or ma...
International Conference of the IEEE Engineerin... 2014:5011 (2014) PMID 25571118We developed a prototype very-large-scale integration chip of a multichannel current stimulator for stimulating neural tissues by utilizing 0.25 μm high-voltage complementary metal-oxide-semiconductor technology. Our designed chip has 20 output channels that are driven by five current buffers ar...
International Conference of the IEEE Engineerin... 2014:5052 (2014) PMID 25571128A persistent question in multivariate neural signal processing is how best to characterize the statistical association between brain regions known as functional connectivity. Of the many metrics available for determining such association, the standard Pearson correlation coefficient (i.e., the z...
International Conference of the IEEE Engineerin... 2014:469 (2014) PMID 25569998Neuronal networks cultured on microelectrode arrays (MEAs) have been utilized as biosensors that can detect all or nothing extracellular action potentials, or spikes. Coating the microelectrodes with carbon nanotubes (CNTs), either pristine or conjugated with a conductive polymer, has been previ...
International Conference of the IEEE Engineerin... 2014:510 (2014) PMID 25570008Using Monte Carlo simulations we optimized the wavelength and source-detector distance (SDD) of a reflectance-based spectroscopic device used for measuring subcutaneous fat thickness. As the optical properties of muscle, fat and dermis are wavelength dependent, it is necessary to choose a wavele...
International Conference of the IEEE Engineerin... 2014:550 (2014) PMID 25570018Based on the Fresnel half-wave band interference, a micromachined self-focusing piezoelectric composite ultrasound transducer was proposed in this paper. The theoretical analysis was deduced based on the concept of constructive interference of acoustic waves and electromechanical response of pie...
International Conference of the IEEE Engineerin... 2014:754 (2014) PMID 25570068Down syndrome is the most common chromosomal condition that presents characteristic facial morphology and texture patterns. The early detection of Down syndrome through an automatic, non-invasive and simple way is desirable and critical to provide the best health management to newborns. In this ...
