    Abstract:

    The heart wall tissue, or the myocardium, is one of the main targets in cardiovascular disease prevention and treatment. Animal models have not been sufficient in mimicking the human myocardium as evident by the very low clinical translation rates of cardiovascular drugs. Additionally, current in vitro models of the human myocardium possess several shortcomings such as lack of physiologically relevant co-culture of myocardial cells, lack of a 3D biomimetic environment, and the use of non-huma…

    Abstract:

    In this work, the droplet size in a water-in-oil emulsion obtained by supersaturation is studied. The emulsion is obtained by cooling down a saturated water/oil solution by a certain temperature difference. The effects of the cooling rate and temperature difference on the produced droplet size are experimentally investigated. The average size of water droplets in the emulsion is found to be proportional to the square root of the cooling rate. By analyzing the time scales of three different st…

    Abstract:

    Super-resolution fluorescence microscopy is an important tool in biomedical research for its ability to discern features smaller than the diffraction limit. However, due to its difficult implementation and high cost, the super-resolution microscopy is not feasible in many applications. In this paper, we propose and demonstrate a saturation-based super-resolution fluorescence microscopy technique that can be easily implemented and requires neither additional hardware nor complex post-processin…

    Abstract:

    Mechanical forces are critical but poorly understood inputs for organogenesis and wound healing. Calcium ions (Ca2+) are critical second messengers in cells for integrating environmental and mechanical cues, but the regulation of Ca2+ signaling is poorly understood in developing epithelial tissues. Here we report a chip-based regulated environment for microorgans that enables systematic investigations of the crosstalk between an organ’s mechanical stress environment and biochemical signaling …

    Abstract:

    Thanks to improvements in biomedical research, biomechanics now combines physiotherapy with models and simulations using motion capture systems. Among possible movements, the lunge motion is often studied as it is a common exercise for muscular training and rehabilitation in which the hip extensors are the dominant muscles. Long and deep lunges are of particular interest because they require greater hip motion in both front and rear legs. In this thesis, markerless motion capture data from 12…

    Eric Matlis, Thomas C. Corke, Sivaram Gogineni
    Patent Number:
    US 7275013 B2
    Description:

    Methods and systems are described for a system for obtaining information regarding a flow. These methods and systems comprise a signal generator configured to generate an alternating current signal at a carrier frequency and a transformer arranged to receive the generated signal, wherein the transformer and carrier frequency are selected so that the generated signal resonates at the carrier frequency. The alternating signal is then used to cause plasma to form across a gap between two electro…

    Patent Number:
    US 7908115 B2
    Description:

    Plasma sensors, systems and related methods are described. An example method for predicting an event includes providing a carrier signal across two electrodes and forming a plasma between the two electrodes. The example method also includes measuring a modulated signal from the plasma, manipulating the modulated signal to produce a value and comparing the value to a threshold. Finally, the example method includes determining the likelihood of the event based on the comparison.

    Patent Number:
    US 6428754 B2
    Description:

    An exhaust gas treatment system and method for treating the exhaust gas of an internal combustion engine includes a catalytic converter and a catalytic preheater or igniter upstream of the catalytic converter. A bypass passage extends around the igniter such that during the ignition period about two-thirds of the exhaust gas is bypassed around the igniter and one-third passes through the igniter. The igniter raises the temperature of the exhaust gases passing therethrough to an adiabatic temp…
