High-resolution optical coherence tomography in vivo using a nano-optic endoscope
(2018)This work establishes a new class of endoscopic optical imaging catheters, termed nano-optic endoscopes, that uses metalenses with the ability to modify the phase of incident light at sub-wavelength level. We utilize the ... -
High-resolution protein folding with a transferable potential
(National Academy of Sciences, 2005)A generalized computational method for folding proteins with a fully transferable potential and geometrically realistic all-atom model is presented and tested on seven helix bundle proteins. The protocol, which includes ... -
High-Resolution Spectroscopy of the Transiting Planet Host Star TrES-1
(American Astronomical Society, 2004)We report on a spectroscopic determination of the stellar parameters and chemical abundances for the parent star of the transiting planet TrES-1. Based on a detailed analysis of iron lines in our Keck and Hobby-Eberly ... -
High-Resolution, High-Aspect Ratio Conductive Wires Embedded in Plastic Substrates
(American Chemical Society (ACS), 2015)A novel method is presented to fabricate high-resolution, high-aspect ratio metal wires embedded in a plastic substrate for flexible electronics applications. In a sequential process, high-resolution channels connected to ... -
High-Responsivity Mid-Infrared Graphene Detectors with Antenna-Enhanced Photocarrier Generation and Collection
(American Chemical Society, 2014)Graphene is an attractive photoconductive material for optical detection due to its broad absorption spectrum and ultrashort response time. However, it remains a great challenge to achieve high responsivity in graphene ... -
High-Sensitivity Measurement of Density by Magnetic Levitation
(American Chemical Society (ACS), 2016)This paper presents methods that use Magnetic Levitation (MagLev) to measure very small differences in density of solid diamagnetic objects suspended in a paramagnetic medium. Previous work in this field has shown that, ... -
High-speed Developments in Avian Genomics
(American Institute of Biological Sciences, 2008)Until recently, definitions of avian genome structure and function were based solely on our knowledge of the chicken genome. The expansion of genomic studies to include nonmodel avian species allows us not only to refine ... -
High-speed surface reconstruction of a flying bird using structured light
(The Company of Biologists, 2017)Birds fly effectively and maneuver nimbly by dynamically changing the shape of their wings during each wingbeat. These shape changes have yet to be quantified automatically at high temporal and spatial resolution. Therefore, ... -
High-Speed, Compact, Adaptive Lenses Using In-Line Transparent Dielectric Elastomer Actuator Membranes
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2013)Electrically tunable adaptive lenses provide several advantages over traditional lens assemblies in terms of compactness, speed, efficiency, and flexibility. We present an elastomer-liquid lens system which makes use of ... -
High-Temperature Operation of Terahertz Quantum Cascade Laser Sources
(Institute of Electrical and Electronics Engineers, 2009)Terahertz (THz) quantum cascade lasers (QCLs) are currently the most advanced electrically pumped semiconductor lasers in the spectral range 1-5 THz. However, their operation at room temperature is still an unresolved ... -
High-Temperature Quantum Anomalous Hall Effect in n − p Codoped Topological Insulators

High-Temperature Superfluidity of Fermionic Atoms in Optical Lattices
(American Physical Society (APS), 2002)Fermionic atoms confined in a potential created by standing wave light can undergo a phase transition to a superfluid state at a dramatically increased transition temperature. Depending upon carefully controlled parameters, ... -
High-temperature tensile behavior of freestanding Au thin films
(Elsevier BV, 2014)The mechanical behavior of freestanding thin sputter-deposited films of Au is studied at temperatures up to 340 °C, using tensile testing. Films tested at elevated temperatures exhibit a significant decrease in flow stress ... -
