Extreme sensitivity displayed by single-crystal diamond deep ultra-violet photoconductive devices
(2009)Deep UV detection using a single crystal diamond (SCD) substrate without a homoepitaxial layer has been demonstrated using a defect passivation treatment. Despite evidence of surface damage on the SCD, the treatments lead ... -
Extreme star formation in the Milky Way: luminosity distributions of young stellar objects in W49A and W51
(2018-07-01)We have compared the star-formation properties of the W49A and W51 regions by using far-infrared data from the Herschel infrared Galactic Plane Survey (Hi-GAL) and 850-μm observations from the James Clerk Maxwell Telescope ... -
An Extreme Starburst in the Core of a Rich Galaxy Cluster at z = 1.7
(2015-08-21)We have discovered an optically rich galaxy cluster at z = 1.7089 with star formation occurring in close proximity to the central galaxy. The system, SpARCS104922.6+564032.5, was detected within the Spitzer Adaptation of ... -
Extremely faint blue-tail stars in ω Centauri

Extremely inefficient star formation in the outer disks of nearby galaxies
(2010)We combine data from The H I Nearby Galaxy Survey and the GALEX Nearby Galaxy Survey to study the relationship between atomic hydrogen (H I) and far-ultraviolet (FUV) emission outside the optical radius (r 25) in 17 spiral ... -
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
(2011)Variable x-ray and gamma-ray emission is characteristic of the most extreme physical processes in the universe. We present multiwavelength observations of a unique gamma-ray-selected transient detected by the Swift satellite, ... -
Extremely massive disc galaxies in the nearby Universe form through gas-rich minor mergers
(2022-01-14)In our hierarchical structure-formation paradigm, the observed morphological evolution of massive galaxies -- from rotationally-supported discs to dispersion-dominated spheroids -- is largely explained via galaxy merging. ... -
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
(2015-11-26)The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars with tiny amounts of elements heavier than ... -
The extremely red L dwarf ULAS J222711-004547-dominated by dust
(2014-03)We report the discovery of a peculiar L dwarf from the United Kingdom Infrared Deep Sky Survey Large Area Survey, ULAS J222711-004547. The very red infrared photometry (MKO J-K = 2.79 +/- 0.06, WISEW1-W2 = 0.65 +/- 0.05) ... -
Extremely red stellar objects revealed by IPHAS
(2008)We present photometric analysis and follow-up spectroscopy for a population of extremely red stellar objects extracted from the point-source catalogue of the INT Photometric H Survey (IPHAS) of the northern galactic plane. ... -
An Extremely Simple Multi-Wing Chaotic System: Dynamics Analysis, Encryption Application and Hardware Implementation
(2020-12-31)Polynomial functions have been the main barrierrestricting the circuit realization and engineering applicationof multi-wing chaotic systems (MWCSs). To eliminate thisbottleneck, we construct a simple MWCS without ... -
Extrinsic factors governing the spore encumbrance of an indigenous population of Pasteuria hyperparasitizing root-knot nematodes, Meloidogyne species.
(2016-08-28)Isolates of indigenous populations of gram-positive endospore-forming bacterial hyperparasite Pasteuria spp. infecting root-knot nematodes were made from arid, semi-arid, humid and sub humid ecosystems of India. A semi-arid ... -

Eye and Voice-Controlled Human Machine Interface System for Wheelchairs Using Image Gradient Approach
(2020-09-26)Rehabilitative mobility aids are being used extensively for physically impaired people. Efforts are being made to develop human machine interfaces (HMIs), manipulating the biosignals to better control the electromechanical ...
