Hybrid Monitors for Concurrent Noninterference
(2015)Controlling confidential information in concurrent systems is difficult, due to covert channels resulting from interaction between threads. This problem is exacerbated if threads share resources at fine granularity. In ... -
Hybrid PET-optical imaging using targeted probes
(National Academy of Sciences, 2010)Fusion imaging of radionuclide-based molecular (PET) and structural data [x-ray computed tomography (CT)] has been firmly established. Here we show that optical measurements [fluorescence-mediated tomography (FMT)] show ... -
A Hybrid Photoreceptor Expressing Both Rod and Cone Genes in a Mouse Model of Enhanced S-Cone Syndrome
(Public Library of Science, 2005)Rod and cone photoreceptors subserve vision under dim and bright light conditions, respectively. The differences in their function are thought to stem from their different gene expression patterns, morphologies, and synaptic ... -
Hybrid Quantum Devices and Quantum Engineering
(IOP Science, 2009)We discuss prospects of building hybrid quantum devices involving elements of atomic and molecular physics, quantum optics and solid-state elements with the attempt to combine advantages of the respective systems in ... -
Hybrid Quantum Processors: Molecular Ensembles as Quantum Memory for Solid State Circuits
(American Physical Society (APS), 2006)We investigate a hybrid quantum circuit where ensembles of cold polar molecules serve as long-lived quantum memories and optical interfaces for solid state quantum processors. The quantum memory realized by collective spin ... -
Hybrid Quantum Systems With Nitrogen Vacancy Centers and Mechanical Resonators
(2020-05-06)Hybrid quantum systems involving coupled mechanical and spin degrees of freedom are promising candidates for applications in quantum metrology and quantum information processing. Specific examples range from sensitive ... -
Hybrid Single-Nanowire Photonic Crystal and Microresonator Structures
(American Chemical Society, 2006)We report a hybrid approach for photonic systems that combines chemically synthesized single nanowire emitters with lithographically defined photonic crystal and racetrack microresonator structures. Finite-difference ... -
Hybrid Soluble and Insoluble 3D Printed Formwork
(2021-05-18)This thesis investigates the potentials of hybrid 3D printed concrete formwork. Water-soluble Polyvinyl Alcohol (PVA) formwork allows for the creation of intricate forms that would be difficult, if not impossible, to create ... -
Hybrid stretchable circuits on silicone substrate
(American Institute of Physics, 2014)When rigid and stretchable components are integrated onto a single elastic carrier substrate, large strain heterogeneities appear in the vicinity of the deformable-non-deformable interfaces. In this paper, we report on a ... -
Hybrid Thermal‐Nonthermal Synchrotron Emission from Hot Accretion Flows
(American Astronomical Society, 2000)We investigate the effect of a hybrid electron population, consisting of both thermal and nonthermal particles, on the synchrotron spectrum, image size, and image shape of a hot accretion flow onto a supermassive black ... -
Hybrid Transitive Trust Mechanisms
(International Foundation for Autonomous Agents and Multiagent Systems, 2010)Establishing trust amongst agents is of central importance to the development of well-functioning multi-agent systems. For example, the anonymity of transactions on the Internet can lead to inefficiencies; e.g., a seller ... -
Hybrid zones and the speciation continuum in Heliconius butterflies
(Wiley-Blackwell, 2012)Tropical butterflies in the genus Heliconius have long been models in the study of the stages of speciation. Heliconius are unpalatable to predators, and many species are notable for multiple geographic populations with ... -
Hybridization in Plants: Old Ideas, New Techniques
(American Society of Plant Biologists (ASPB), 2016-11-28)Hybridization has played an important role in the evolution of many lineages. With the growing availability of genomic tools and advancements in genomic analyses, it is becoming increasingly clear that gene flow between ... -
Hybridization promotes color polymorphism in the aposematic harlequin poison frog, Oophaga histrionica
(Blackwell Publishing Ltd, 2013)Whether hybridization can be a mechanism that drives phenotypic diversity is a widely debated topic in evolutionary biology. In poison frogs (Dendrobatidae), assortative mating has been invoked to explain how new color ... -

Hydrated sulphuric acid in dense molecular clouds
(Oxford University Press (OUP), 2003)We consider sulphur depletion in dense molecular clouds, and suggest hydrated sulphuric acid, H2SO4 · nH2O, as a component of interstellar dust in icy mantles. We discuss the formation of hydrated sulphuric acid in collapsing ... -
Hydration of Single Crystals of Dipalmitoylphosphatidylcholine
(National Academy of Sciences, 1981)Optical birefringence and x-ray measurements are reported for single crystals \((0.5 mm \times 2 mm \times 5 \mu m)\) of dipalmitoylphosphatidylcholine as a function of temperature and relative humidity. Large single ... -
Hydraulic Control of Mammalian Embryo Size and Cell Fate
(Springer Science and Business Media LLC, 2019-06-12)Size control is fundamental in tissue development and homeostasis1,2. While the role of cell proliferation in these processes has been widely studied, the mechanisms of embryo size control and how it impacts cell fates ... -

Hydrocarbon-Stapled Peptides: Principles, Practice, and Progress: Miniperspective
(American Chemical Society, 2014)Protein structure underlies essential biological processes and provides a blueprint for molecular mimicry that drives drug discovery. Although small molecules represent the lion’s share of agents that target proteins for ...
