EXERCISE-INDUCED ACUTE CHANGES IN SYSTOLIC BLOOD PRESSURE DO NOT ALTER CHOROIDAL THICKNESS AS MEASURED BY A PORTABLE SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY DEVICE
(Ovid Technologies (Wolters Kluwer) - Lippincott Williams & Wilkins, 2013-01)Purpose: To measure choroidal thickness in patients manifesting an acute change in systemic arterial blood pressure using a portable spectral-domain optical coherence tomography device (iVue). Methods: Fifteen patients ... -
Exergy analysis of a high-temperature-steam-driven, varied-pressure, humidification–dehumidification system coupled with reverse osmosis
(Elsevier, 2012-11)In this study, exergy analysis of a novel desalination system is presented and discussed. The water desalination is carried out using combined humidification–dehumidification and reverse osmosis technologies. Six system ... -
Exergy analysis of incremental sheet forming
(Springer Science + Business Media B.V., 2012-03)Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical ... -
Exhaled aerosol increases with COVID-19 infection, age, and obesity
(Proceedings of the National Academy of Sciences, 2021-02)COVID-19 transmits by droplets generated from surfaces of airway mucus during processes of respiration within hosts infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. We studied respiratory ... -
Exhumation of the UHP Tso Morari eclogite as a diapir rising through the mantle wedge
(Springer Berlin Heidelberg, 2015-01)Ultrahigh-pressure (UHP) rocks such as the coesite-bearing eclogites, occurring as boudins within felsic gneisses of the Tso Morari dome in northwestern Himalayas, originated through subduction of the northern continental ... -
Existence and classification of overtwisted contact structures in all dimensions
(Springer Netherlands, 2016-02)We establish a parametric extension h-principle for overtwisted contact structures on manifolds of all dimensions, which is the direct generalization of the 3-dimensional result from. It implies, in particular, that any ... -
Existence and hardness of conveyor belts
(The Electronic Journal of Combinatorics, 2020-10)An open problem of Manuel Abellanas asks whether every set of disjoint closed unit disks in the plane can be connected by a conveyor belt, which means a tight simple closed curve that touches the boundary of each disk, ... -
Existence h-principle for Engel structures
(Springer Berlin Heidelberg, 2017-05)In this article we prove that the inclusion of the space of Engel structures of a smooth 4-manifold into the space of full flags of its tangent bundle induces surjections in all homotopy groups. In particular, we construct ... -

Existence of minimal hypersurfaces in complete manifolds of finite volume
(Springer Berlin Heidelberg, 2020-08)We prove that every complete non-compact manifold of finite volume contains a (possibly non-compact) minimal hypersurface of finite volume. The main tool is the following result of independent interest: if a region U can ... -
Existence of Minimal Models for Varieties of Log General Type
(American Mathematical Society, 2010-01)We prove that the canonical ring of a smooth projective variety is finitely generated. -
Existence of Minimal Models for Varieties of Log General Type II.
(American Mathematical Society, 2010-01)Assuming finite generation in dimension $ n-1$, we prove that pl-flips exist in dimension $ n$. -
Existence of minimal surfaces of arbitrarily large Morse index
(Springer Berlin Heidelberg, 2016-05)We show that in a closed 3-manifold with a generic metric of positive Ricci curvature, there are minimal surfaces of arbitrary large Morse index, which partially confirms a conjecture by Marques and Neves. We prove this ... -
Exo-C: a probe-scale space mission to directly image and spectroscopically characterize exoplanetary systems using an internal coronagraph
(SPIE, 2014-06)"Exo-C" is NASA's first community study of a modest aperture space telescope designed for high contrast observations of exoplanetary systems. The mission will be capable of taking optical spectra of nearby exoplanets in ... -
Exo-C: a probe-scale space observatory for direct imaging and spectroscopy of extrasolar planetary systems
(SPIE, 2015-08)"Exo-C" is NASAs first community study of a modest aperture space telescope mission that is optimized for high contrast observations of exoplanetary systems. The mission will be capable of taking optical spectra of nearby ... -
The Exo-S probe class starshade mission
(SPIE, 2015-08)Exo-S is a direct imaging space-based mission to discover and characterize exoplanets. With its modest size, Exo-S bridges the gap between census missions like Kepler and a future space-based flagship direct imaging exoplanet ... -
Exocompilation for Productive Programming of Hardware Accelerators

Exocyclic Carbons Adjacent to the N[superscript 6] of Adenine are Targets for Oxidation by the Escherichia coli Adaptive Response Protein AlkB
(American Chemical Society (ACS), 2012-04)The DNA and RNA repair protein AlkB removes alkyl groups from nucleic acids by a unique iron- and α-ketoglutarate-dependent oxidation strategy. When alkylated adenines are used as AlkB targets, earlier work suggests that ... -
