Electrically Conductive Nanomaterials Reinforced Cardiac Microtissues
Technology: Progenitor cells provide strong regenerative ability, but are limited by their immature phenotype and inability to generate functional tissues equivalent to adult cardiomyocytes. This technology provides a novel approach to successfully regenerate functional cardiomyocytes from progenitor cells. The strategy involves providing a physiologically-relevant...

Low-power SAR ADC design
Background A successive approximation analog-to-digital converter (ADC) is used to digitize the physical analog signals to logic digital signals. It often requires low noise to achieve high accuracy. Traditionally the low noise is realized by utilizing a large comparator or averaging. Those methods are not desirable, since a large comparator is power-hungry...

Floating inverter pre-amplifier based dynamic comparator
Background Two technologies are touched upon. First is an energy-efficient comparator, followed by a time domain two-step capacitance-to-digital converter. Comparators bridge the analog and digital world. A low-power, low-noise comparator is critical for analog-to-digital converters. A comparator consists of a pre-amp followed by a latch. Dynamic comparators,...

Chance-Constrained Optimization for Treatment of Prostate and Other Cancers in Intensity-Modulated Proton Therapy
The quality of IMPT treatment plans may be drastically diminished by uncertainties such as proton range and patient setup errors. If these uncertainties are not figured into treatment planning, the dose distribution that the patient receives may not be the same as the planned dose distribution. New treatment plans, which include optimized software/programming,...

Improved Differentiation of Stem Cells into Cardiac Muscle Cells for Cardiac Tissue Repair
This approach advances the maturation of stem cells or progenitor cells, cells that differentiate like stem cells, to produce functional, biocompatible cardiomyocytes for the repair of damaged cardiac tissue. Cardiomyocytes are specialized cardiac muscle cells essential for cardiac muscle health. Cardiovascular disease, the leading cause of death worldwide,...
