(John Wiley, 2017)Semi-conducting polyethylene (PE) nanocomposites with outstanding magnetic properties at room temperature were synthesized. These exceptional properties, for a diamagnetic and insulating matrix as PE, were obtained by ...
-
(ACM, 2017)We prove the existence of an algorithmAfor computing 2D or 3D convex hulls that is optimal forevery pointsetin the following sense: for every sequenceσofnpoints and for every algorithmA′in a certain classA,the running time ...
-
(Elsevier, 2017)tEnzymes active at low temperature are of great interest for industrial bioprocesses due to their highefficiency at a low energy cost. One of the particularities of naturally evolved cold-active enzymes istheir increased ...
-
(Springer, 2017)Discord Discovery is a recent approach for anomaly detection in time series that has attracted much research because of the wide variety of real-world applications in monitoring systems. However, finding anomalies by ...
-
(Institute of Physics Publishing, 2017)In multi-field inflation one or more non-adiabatic modes may become light, potentially inducing large levels of isocurvature perturbations in the cosmic microwave background. If in addition these light modes are coupled ...
-
(Institute of Physics Publishing, 2017)Numerical simulations were used to study the dynamics of a passive conservedscalar quantity entrained by a self-propelling viscous vortex ring. The trans-port and mixing process of the passive scalar variable were studied ...
-
(Elsevier, 2017)The synthesis of unsymmetrical ferrocenyl and cyrhetrenyl azines [(h5-C5H4)-CR¼N-N¼CH-2-C4H2X-5-NO2]M (M¼Re(CO)3, Fe(h5-C5H5); R¼H, CH3,X¼O, S) has led to the development of new derivativesof 5-nitroheterocycles as potential ...
-
(INFORMS Inst.for Operations Res.and the Management Sciences, 2017)Public transit systems in major urban areas usually operate under deficits and therefore require significant subsidies. An important cause of this deficit, particularly in the developing world, is the high fare evasion ...
-
(American Meteorological Society, 2017)The existence of strong easterly winds down the western slope of the south-central Andes in Chile, locallyknown as Puelche winds, has been known by the meteorological community since at least the mid-twentiethcentury. ...
-
(Springer Verlag, 2017)JavaScript systems are becoming increasingly complex and large. To tackle the challenges involved in implementing these systems, the language is evolving to include several constructions for programmingin- the-large. ...
-
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)Reverse engineering problems for conjunctive queries (CQs), such as query by example (QBE) ordefinability, take a set of user examples and convert them into an explanatory CQ. Despite theirimportance, the complexity of ...
-
(Cambridge University, 2017)Waves patterns in the Faraday instability have been studied for decades. Besides therich dynamics that can be observed on the waves at the interface, Faraday waves hidebeneath them an elusive range of flow patterns —or ...
-
(American Society of Civil Engineers (ASCE), 2017)Treatment of drinking water for arsenic (As) removal has been implemented in centralized facilities worldwide, reflecting the increasingly stringent national and international drinking water standards for As, for which a ...
-
(Elsevier, 2017)A numerical method based on artificial neural networks is used to solve the inverse Schrödinger equation for a multi-parameter class of potentials. First, the finite element method was used to solve repeatedly the direct ...
-
(Oxford University, 2017)We have conducted a search for optical circumstellar absorption lines in the spectra of 16 debris disc host stars. None of the stars in our sample showed signs of emission line activity in either Hα, CaII or Na I, confirming ...
-
(Taylor and Francis, 2017)Correlation between theoretical and experimental (infrared and Raman spectroscopies) vibrational spectra of two compounds, both with a silyl group present in their main chain and with an optically active structure (L-valine) ...
-
(Elsevier, 2017)Heritage buildings in Latin American countries possess high architectural value. Studying these constructions under extreme loads, particularly earthquakes, requires representative models for simulating expected response. ...
-
(Oxford University, 2017)Despite their close proximity, the complex interplay between the two Magellanic Clouds, theMilky Way and the resulting tidal features, is still poorly understood. Recent studies haveshown that the Large Magellanic Cloud ...
-
(IEEE, 2017)As part of transmission network expansion planning(TNEP), a technical and economical assessment of several planningalternatives must be performed in order to ensure fulfillment of thenetwork security criteria and to estimate ...
-
(Elsevier, 2017)Natural geothermal systems are limited areas characterized by anomalously high heat flowcaused by recent tectonic ormagmatic activity. The heat source at depth is the result of the emplacement ofmagmabodies, controlled by ...
