Acoustic resonators with integrated microfluidic channels for ultra-high Q-factor: a new paradigm for in-liquid gravimetric detection
(2023)Biosensing is a critical area of research that involves detecting and measuring biological molecules. Among the various types of biosensors, acoustic biosensors are attractive for their simplicity, robustness, and low cost, ... -
Characterizing the Switching Thresholds of Magnetophoretic Transistors.
(Adv Mater, 2015-10-28)The switching thresholds of magnetophoretic transistors for sorting cells in microfluidic environments are characterized. The transistor operating conditions require short 20-30 mA pulses of electrical current. By demonstrating ... -
Enhancing imaging systems using transformation optics.
(Opt Express, 2010-09-27)We apply the transformation optical technique to modify or improve conventional refractive and gradient index optical imaging devices. In particular, when it is known that a detector will terminate the paths of rays over ... -
Evaluation of high-perimeter electrode designs for deep brain stimulation.
(Journal of neural engineering, 2014-08)<h4>Objective</h4>Deep brain stimulation (DBS) is an effective treatment for movement disorders and a promising therapy for treating epilepsy and psychiatric disorders. Despite its clinical success, complications including ... -
Evaluation of intradural stimulation efficiency and selectivity in a computational model of spinal cord stimulation.
(PloS one, 2014-01)Spinal cord stimulation (SCS) is an alternative or adjunct therapy to treat chronic pain, a prevalent and clinically challenging condition. Although SCS has substantial clinical success, the therapy is still prone to failures, ... -
Influences of interpolation error, electrode geometry, and the electrode-tissue interface on models of electric fields produced by deep brain stimulation.
(IEEE transactions on bio-medical engineering, 2014-02)Deep brain stimulation (DBS) is an established therapy for movement disorders, but the fundamental mechanisms by which DBS has its effects remain unknown. Computational models can provide insights into the mechanisms of ... -
Springback Analysis for Rod Bending in Spinal Fusion Surgery Applications
(2010)Spinal fusion is quickly becoming a common surgical operation in today's medical field. A major component of spinal fusion surgery is the use of metal rods. These rods, which are made of titanium or stainless steel, must ... -
The Ductile to Brittle Transition in Polycarbonate
(2011)An advanced bulk constitutive model is used with a new cohesive zone model that is stress state and rate-dependent in order to simulate the ductile to brittle failure transition in polycarbonate. The cohesive zone model ... -
The effect of posterior polyester tethers on the biomechanics of proximal junctional kyphosis: a finite element analysis.
(Journal of neurosurgery. Spine, 2017-01)OBJECTIVE Proximal junctional kyphosis (PJK) remains problematic following multilevel instrumented spine surgery. Previous biomechanical studies indicate that providing less rigid fixation at the cranial aspect of a long ...
