The Extreme Spin of the Black Hole in Cygnus X-1
(IOP Publishing, 2011)The compact primary in the X-ray binary Cygnus X-1 was the first black hole to be established via dynamical observations. We have recently determined accurate values for its mass and distance, and for the orbital inclination ... -
Extremely durable biofouling-resistant metallic surfaces based on electrodeposited nanoporous tungstite films on steel
(Nature Pub. Group, 2015)Formation of unwanted deposits on steels during their interaction with liquids is an inherent problem that often leads to corrosion, biofouling and results in reduction in durability and function. Here we report a new route ... -
An extremely energetic supernova from a very massive star in a dense medium

Extremely Stable Anthraquinone Negolytes Synthesized from Common Precursors
(Elsevier BV, 2020-06)Synthetic cost and long-term stability remain two of the most challenging barriers for the utilization of redox-active organic molecules in redox flow batteries for grid scale energy storage. Starting from potentially ... -
An Extremely Stable, Highly Soluble Monosubstituted Anthraquinone for Aqueous Redox Flow Batteries
(Wiley, 2023-01-24)An extremely stable, energy‐dense (53.6 Ah L<jats:sup>−1</jats:sup>, 2 <jats:sc>m</jats:sc> transferrable electrons), low crossover (permeability of <1 × 10<jats:sup>−13</jats:sup> cm<jats:sup>2</jats:sup> s<jats:sup> ... -
Extremely Stretchable and Fast Self-Healing Hydrogels
(Wiley, 2016-04-09)Dynamic crosslinking of extremely stretchable hydrogels with rapid self-healing ability is described. Using this new strategy, the obtained hydrogels are able to elongate 100 times compared to their initial length and to ... -
Extrusion, slide, and rupture of an elastomeric seal
(Elsevier BV, 2017)Elastomeric seals are essential to two great technological advances in oilfields: horizontal drilling and hydraulic fracturing. This paper describes a method to study elastomeric seals by using the pressure-extrusion curve ... -
Eye Movements during Auditory Attention Predict Individual Differences in Dorsal Attention Network Activity
(Frontiers Media S.A., 2016)The neural mechanisms supporting auditory attention are not fully understood. A dorsal frontoparietal network of brain regions is thought to mediate the spatial orienting of attention across all sensory modalities. Key ... -
The eye of the storm: light from the inner plunging region of black hole accretion discs
(Oxford University Press (OUP), 2012)It is generally thought that the light coming from the inner plunging region of black hole accretion discs contributes negligibly to the disc's overall spectrum, i.e. the plunging fluid is swallowed by the black hole before ... -
Eye-specific retinogeniculate segregation proceeds normally following disruption of patterned spontaneous retinal activity
(BioMed Central, 2014)Background: Spontaneous retinal activity (SRA) is important during eye-specific segregation within the dorsal lateral geniculate nucleus (dLGN), but the feature(s) of activity critical for retinogeniculate refinement are ... -
EZH2 inhibition sensitizes BRG1 and EGFR mutant lung tumors to TopoII inhibitors
(2014)SUMMARY Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide1. Chemotherapies such as the topoisomerase II inhibitor (TopoIIi) etoposide effectively reduce disease in a minority of NSCLC ... -
F-theory and N= 1 SCFTs in four dimensions

F-theory and Neutrinos: Kaluza-Klein Dilution of Flavor Hierarchy
(Springer Verlag, 2010)We study minimal implementations of Majorana and Dirac neutrino scenarios in F-theory GUT models. In both cases the mass scale of the neutrinos \(m_{\nu} \sim M_{weak}^2/\land_{UV}\) arises from integrating out Kaluza-Klein ... -
F-theory and the classification of little strings
(American Physical Society, 2016)Little string theories (LSTs) are UV complete nonlocal six-dimensional (6D) theories decoupled from gravity in which there is an intrinsic string scale. In this paper, we present a systematic approach to the construction ... -
F-theory, GUTs, and the Weak Scale
(Springer Verlag, 2009)In this paper we study a deformation of gauge mediated supersymmetry breaking in a class of local F-theory GUT models where the scale of supersymmetry breaking determines the value of the mu term. Geometrically correlating ... -
F-Theory, spinning black holes and multi-string branches
(Springer Verlag, 2016)We study 5d supersymmetric black holes which descend from strings of generic N = (1, 0) supergravity in 6d. These strings have an F-theory realization in 6d as D3 branes wrapping smooth genus g curves in the base of elliptic ... -
Fabrication and Replication of Arrays of Single- or Multicomponent Nanostructures by Replica Molding and Mechanical Sectioning
(American Chemical Society (ACS), 2010)This paper describes the fabrication of arrays of nanostructures (rings, crescents, counterfacing split rings, cylinders, coaxial cylinders, and other structures) by a four-step process: (i) molding an array of epoxy posts ... -
Fabrication and Sub-Band-Gap Absorption of Single-Crystal Si Supersaturated with Se by Pulsed Laser Mixing
(Springer, 2010)Selenium supersaturated silicon layers were fabricated by pulsed excimer laser induced liquid-phase mixing of thin Se films on Si(001) wafers. Sufficiently low Se coverage avoids destabilization of rapid epitaxial ... -
Fabrication methods for a quantum cascade photonic crystal surface emitting laser
(American Vacuum Society, 2003)Conventional quantum cascade (QC) lasers are intrinsically edge-emitting devices with mode confinement achieved via a standard mesa stripe configuration. Surface emission in edge emitting QC lasers has therefore necessitated ... -
