Independent and Hitting Sets of Rectangles Intersecting a Diagonal Line: Algorithms and Complexity (Springer, 2015)Given a set of n axis-parallel rectangles in the plane, finding a maximum independent set (MIS), amaximumweighted independent set (WMIS), and aminimum hitting set (MHS), are basic problems in computational geometry and ...
-
(Springer, 2017)In the setting of symbolic dynamics on discrete finitely generated infinite groups, we define a model of finite automata with multiple independent heads that walk on Cayley graphs, called group-walking automata, and use ...
-
(The American Astronomical Society, 2013-08)In 2006, Prochter et al. reported a statistically significant enhancement of very strong Mgii absorption systems intervening the sight lines to gamma-ray bursts (GRBs) relative to the incidence of such absorption along ...
-
(Rocky MT Math Consortiumariz State Univ, Dept Math, 2020)Let X, Y be asymmetric normed spaces and Lc(X, Y ) the convex cone of all linear continuous operators from X to Y . It is known that in general, Lc(X, Y ) is not a vector space. The aim of this note is to give, using ...
-
(Springer Verlag, 2018)There are efficient dynamic programming solutions to the computation of the Edit Distance from S ∈in [1..σ]n to T ∈in [1..σ]m, for many natural subsets of edit operations, typically in time within O(nm) in the worst-case ...
-
(MDPI AG, 2017)Geostatistics offers a set of methods for modeling, predicting, or simulating geological domains in space. In addition of being an input of some of these methods, indicator direct and cross-variograms convey valuable ...
-
(Elsevier, 2016)The local critical coalescence concentration l-CCC presents a relationship between frother concentration and the gas flow rate Q(g)' at which coalescence starts to occur at a capillary tube. Such a relationship is used in ...
-
(Blackwell Publishing Ltd, 2019)© 2018 John Wiley & Sons Ltd/CNRS Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population ...
-
(John Wiley and Sons Ltd, 2018)This paper presents the induced heavy ordered weighted moving average (IHOWMA) operator. It is an aggregation operator that uses the main characteristics of three well-known techniques: the moving average, induced operator, ...
-
(IEEE, 2017)The presence of both electronic-converter-based and rotating-machine-based energy sources in microgrids poses a challenge for its stable operation. Most of the stability studies in microgrids have been focused on the ...
-
(John Wiley, 2012-01)In this paper two new schemes for induction motor control are proposed and compared. Both approaches are based on the concept of adaptive passivity. First, a technique using the scheme of field oriented control (FOC) is ...
-
(Emerald Group Publishing Ltd., 2019)© 2018, Emerald Publishing Limited. Purpose: The purpose of this paper is to determine the most influential countries and universities that have contributed to science in the field of industrial marketing research during ...
-
(Elsevier B.V., 2019)Long-standing literature argues that social capital is closely implicated in labour market outcomes. However, this hypothesis has yet to be tested in Latin America, the most unequal region in the world. We focus on Chile, ...
-
(The American Physical Society, 2010)Thin fluid films can have surprising behavior depending on the boundary conditions enforced, the energy input and the specific Reynolds number of the fluid motion. Here we study the equations of motion for a thin fluid ...

Infall signatures in a prestellar core embedded in the high-mass 70 mu m Dark IRDC G331.372-00.116 (IOP Publishing, 2018-07)Using Galactic Plane surveys, we have selected a massive (1200M circle dot), cold (14 K) 3.6-70 mu m dark IRDC, G331.372-00.116. This infrared dark cloud (IRDC) has the potential to form high-mass stars, and given the ...

(Royal Astronomical Society, 2015)We present molecular line imaging observations of three massive molecular outflow sources, G333.6–0.2, G333.1–0.4, and G332.8–0.5, all of which also show evidence for infall, within the G333 giant molecular cloud (GMC). ...
-
(MDPI, 2021)This article discusses the results of an experimental study of a spill of mineral particles in gravel-bed rivers due to mining accidents. The purpose of this research is to characterize the dynamics of the fine mining ...
-
(Springer, 2018-09)We consider a general minimal time problem with a convex constant dynamics and a lower semicontinuous extended real-valued target function defined on a Banach space. If the target function is the indicator function of a ...
-
(Springer, 2017)This paper is the continuation of our study of a general minimal time problem with a convex constant dynamics and a lower semicontinuous extended real-valued target function defined on a Banach space. We study several ...
-
(Siam Publications, 2018)We continue the investigation of a general minimal time problem with a convex constant dynamics and a lower semicontinuous extended real-valued target function defined on a Banach space. In this paper we obtain an explicit ...
