Hydra II: a faint and compact milky way dwarf galaxy found in the survey of the magellanic stellar history
(2015-05-01)We present the discovery of a new dwarf galaxy, Hydra II, found serendipitously within the data from the ongoing Survey of the Magellanic Stellar History conducted with the Dark Energy Camera on the Blanco 4 m Telescope. ... -
Hydraulic characterization of Diesel and water emulsions using momentum flux
(2015-12-15)Diesel and water emulsions have the potential to be used in compression ignition engines to control the emissions of NOx and PM. Very little is known about the influence emulsification will have on the fuel sprays formed ... -
Hydrodynamics and radiation from a relativistic expanding jet with applications to GRB afterglow
(American Institute of Physics (AIP), 2000)We describe fully relativistic three dimensional calculations of the slowing down and spreading of a relativistic jet by an external medium like the ISM. We calculate the synchrotron spectra and light curves using the ... -
Hydrology of the combination irrigation system in the Wadi Faynan, Jordan
(2009)The field system of the Wadi Faynan in southern Jordan was fed by an ancient combination irrigation system that incorporated runoff farming and diversion irrigation techniques. The hydraulic characteristics of this system ... -
Hydrophobic core and surface charges of human beta-2-microglobulin probed by CD measurements
(1992-05)The roles of hydrophobic bonding and charge electrostatics in the stabilization of human beta-2-microglobulin have been probed by variations in solution conditions and monitored by circular dichroism in the near and far ... -

Hydrostatic and explosive nucleosynthesis in massive stars using improved nuclear and stellar physics
(2003-05-05)We have performed the first calculations to follow the evolution of all stable nuclei and their radioactive progenitors in a finely-zoned stellar model computed from the onset of central hydrogen burning through explosion ... -
Hydrothermal performance of inline and staggered arrangements of airfoil shaped pin-fin heat sinks: A comparative study
(2023-01-01)The distinctive airfoil shaped pin-fins offer minimal resistance to fluid flow and enormous effective area due to the delayed fluid separation at the tail. In this article, the hydrothermal performance of inline and staggered ... -
Hygroscopic properties and extinction of aerosol particles at ambient relative humidity in South-Eastern China
(2008-08)During the "Program of Regional Integrated Experiments of Air Quality over Pearl River Delta 2004 (PRIDE-PRD2004)" hygroscopic properties of particles in the diameter range 22 nm to 10 μ m were determined. For that purpose, ... -
The Hyper-MUCHFUSS project : probing the Galactic halo with sdB stars
(2011)Context. High-velocity stars in the Galactic halo, e. g. the so-called hyper-velocity stars (HVS), are important tracers of the properties of the dark matter halo, in particular its mass. Aims. A search for the fastest ... -
Hyperanxiety produced by periaqueductal gray injection of chondroitin sulphate glycosaminoglycan
(2001)We examined the effects of chondroitin sulphate C (CSC) on fear and anxiety parameters following injection of the glycosaminoglycan into the dorsal periaqueductal gray. Rats with chronically implanted cannulae were ... -
The Hyperbolic Superposition of a General Quantum State
(2016-06-28)This dissertation documents an inquiry into the geometric structure of the Spaces used to represent a 2-Dimensional Quantum State Space as it relates to Quantum Computation. In particular we investigate the possible ... -
Hyperchaotic Bilateral Random Low-Rank Approximation Random Sequence Generation Method and Its Application on Compressive Ghost Imaging
(2024-02-15)Hyperchaotic systems have been widely used in the field of communication and information security to generate random numbers due to their super-long sequences, pseudo-randomness, and unpredictability. However, chaotic ... -
Hyperchaotic memristive ring neural network and application in medical image encryption
(2022-06-29)Neural networks are favored by academia and industry because of their diversity of dynamics. However, it is difficult for ring neural networks to generate complex dynamical behaviors due to their special structure. In this ... -
Hyperconnectivity of the ventromedial prefrontal cortex in obsessive-compulsive disorder
(2018-11-30)Neuroimaging research has highlighted maladaptive thalamo-cortico-striatal interactions in obsessive-compulsive disorder as well as a more general deficit in prefrontal functioning linked with compromised executive ... -
Hypergranulation : Exploring possible management options
(2010-01-01)Hypergranulation (or overgranulation) is an excess of granulation tissue beyond the amount required to replace the tissue deficit incurred as a result of skin injury or wounding. An infrequent but not rare consequence of ... -
Hyperhidrosis quality of life index (HidroQoL): further validation by applying classical test theory and item response theory using data from a phase III clinical trial
(2023-06-06)Background: The Hyperhidrosis Quality of Life Index (HidroQoL ©) is a well-developed and validated patient-reported outcome measure assessing the quality-of-life impacts in hyperhidrosis with 18 items. Our aim was to extend ... -
