(Oxford University Press, 2015)We combine previously published interferometric and single-dish data of relatively nearby massive dense cores that are actively forming stars to test whether their 'fragmentation level' is controlled by turbulent or thermal ...
-
(IOP Publishing, 2015)Wepresent an experimental and theoretical study on the gravity-wave instability developing in a highly turbulent free-surface Taylor–Couette flow, for which only the inner cylinder rotates. Above a critical rotation ...
-
(EDP Sciences, 2017)Since the first discovery of a broad-lined type Ic supernova (SN) with a long-duration gamma-ray burst (GRB) in 1998, fewer than fifty GRB-supernovae (SNe) have been discovered. The intermediate-luminosity Swift GRB 161219B ...
-
(2010)We present the discovery of an absorption-line redshift of z = 2.609 for GRB 090426, establishing the first firm lower limit to a redshift for a gamma-ray burst (GRB) with an observed duration of <2 s.With a rest-frame ...

(IEEE, 2016)A TCAM-based flow table is power-hungry hardware that can provide high-speed lookup operations for packet switching networks. A number of energy-efficient TCAM usage approaches have been proposed in recent literature, but ...

(Springer New York LLC, 2019)© 2018, Springer Science+Business Media, LLC, part of Springer Nature.While the number of things is growing accompanied with an explosive increase in wireless traffic, network providers are facing a set of challenges, ...
-
(Elsevier, 2022)The present work primarily focused on isolation of Chlorella vulgaris from industrial wastewater, and use as an effective feedstock for producing renewable biodiesel. Post isolation, the lipid was extracted from Chlorella ...
-
(Taylor & Francis, 2017)Over the last few years, the green synthesis of nanoparticles (NPs) using plant extracts has emerged as a promising methodology for the fabrication of metallic NPs (especially silver, copper, and gold NPs), as it involves ...
-
(European Mathematical Society, 2020)Let Omega be a smooth bounded domain in R-n, n >= 5. We consider the classical semilinear heat equation at the critical Sobolev exponent. ut =Delta u + un+2/n-2 in Omega x (0, infinity), u = 0 on partial derivative Omega ...
-
(Elsevier, 2015)Hydropeaking operations can severely degrade ecosystems. As variable renewable sources (e.g. wind power) are integrated into a power grid, fluctuations in the generation-demand balance are expected to increase. In this ...
-
(Wiley & Sons, 2015)In this work, we study the existence of positive solutions for a class of fractional differential equation given by D-t(infinity-infinity)alpha D(t)(alpha)u(t) + u(t) = f(t,u(t)), u is an element of H-alpha (R), ...
-
(IOP Publishing, 2015)We consider here solutions of the nonlinear fractional Schr¨odinger equation ε2s(− )su + V (x)u = up. We show that concentration points must be critical points for V . We also prove that if the potential V is coercive ...

Ground-based detection of calcium and possibly scandium and hydrogen in the atmosphere of HD209458b (EDP Sciences, 2013)Context. Since the first exoplanetary atmosphere detection using the Hubble Space Telescope, characterization of exoplanet atmospheres from the ground have been playing an increasingly important role in the analysis of ...
-
(Oxford University Press, 2018-07)We present high cadence detections of two superflares from a bright G8 star (V = 11.56) with the Next Generation Transit Survey (NGTS). We improve upon previous superflare detections by resolving the flare rise and peak, ...
-
(EDP, 2014)Context. GJ 1214 b is one of the few known transiting super-Earth-sized exoplanets with a measured mass and radius. It orbits an M-dwarf, only 14.55 pc away, making it a favorable candidate for follow-up studies. However, ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005)The list of Ground-Level Enhancements (GLEs) occurring during the on-going solar cycle (no. 23) is used to show that they are absent during a time interval of the maximum phase in which a relative reduction in the sunspot ...
-
(Springer, 2016-11)In order to identify the origin of the main processes that affect the composition of groundwater in a karstic aquifer, a hydrogeochemical and isotopic study was carried out of water from numerous observation wells located ...
-
(ASCE-AMER SOC CIVIL ENGINEERS, 2008-04)This work presents a novel approach for solving groundwater management problems with reduced computational effort. We replace a groundwater flow model governed by a partial differential equation with a simple model governed ...
