(Springer, 2020)Random fields on the sphere play a fundamental role in the natural sciences. This paper presents a simulation algorithm parenthetical to the spectral turning bands method used in Euclidean spaces, for simulating scalar- ...
-
(Oxford University Press, 2020)Some universal solutions are studied for a new class of elastic bodies, wherein the Hencky strain tensor is assumed to be a function of the Kirchhoff stress tensor, considering in particular the case of assuming the bodies ...

Seawater flocculation of clay-based mining tailings: Impact of calcium and magnesium precipitation (Elsevier, 2020)In areas where access to water of good quality is limited, the use of seawater in mineral processing can be an option. However, the dewatering of waste tailings is adversely affected, particularly when this follows processing ...
-
(Elsevier, 2020)Reinforcement learning (RL) provides an alternative method for designing condition-based decision making in engineering systems. In this study, a simple and flexible RL tabular Q-learning framework is employed to identify ...
-
(Elsevier, 2020)Perfect graphs form a well-known class of graphs introduced by Berge in the 1960s in terms of a min-max type equality involving two famous graph parameters. In this work, we survey certain variants and subclasses of perfect ...
-
(IOP Publishing, 2020)We present evidence for localized deviations from Keplerian rotation, i.e., velocity "kinks," in 8 of the 18 circumstellar disks observed by the DSHARP program: DoAr 25, Elias 2-27, GW Lup, HD 143006, HD 163296, IM Lup, ...
-
(Elsevier, 2020)Micro-reversibility plays a central role in thermodynamics and statistical mechanics. It is used to prove that systems in contact with a thermal bath relax to canonical ensembles. However, a problem arises when trying to ...
-
(Springer, 2020)We provide some necessary and sufficient conditions for a proper lower semicontinuous convex function, defined on a real Banach space, to be locally or globally Lipschitz continuous. Our criteria rely on the existence of ...
-
(Elsevier, 2020)Hartsfield and Ringel in 1990 conjectured that any connected graph with q >= 2 edges has an edge labeling f with labels in the set {1,..., q}, such that for every two distinct vertices u and v, f(u) not equal= f(v), where ...
-
(Copernicus Gesellschaft MBH, 2020)Detecting and understanding historical changes in the frequency of geo-climatic hazards (G-CHs) is crucial for the quantification of current hazards and project them into the future. Here we focus in the eastern subtropical ...
-
(American Institute of Physics, 2020)Homogeneously driven dynamical systems exhibit multistability. Depending on the initial conditions, fronts present a rich dynamical behavior between equilibria. Qualitatively, this phenomenology is persistent under spatially ...
-
(Geological Soc Publ House, 2020)The scarce Eocene geological record in the Andean region of Central Chile (c. 33.6 degrees S) is represented by the Estratos del Cordon de los Ratones unit. This is a c. 450 m thick, mainly volcanic, continental series ...

(American Institute of Physics, 2020)Distributed generation (DG) has experienced extraordinary growth in installed capacity in many countries. DG can have a significant impact on both the investment and operational costs of distribution feeders. However, in ...
-
(Elsevier, 2020)In this study, we analyze 100 crustal Precordilleran earthquakes recorded in 2008 and 2009 by 52 broadband seismic stations from the SIEMBRA and ESP, two temporary experiments deployed in the Pampean flat slab region, ...
-
(Wiley, 2020)Skeletal muscle atrophy is characterized by the degradation of myofibrillar proteins, such as myosin heavy chain or troponin. An increase in the expression of two muscle-specific E3 ligases, atrogin-1 and MuRF-1, and ...
-
(Springer, 2020)The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of ...
-
(Elsevier, 2020)The supply of natural gas is generally based on contracts that are signed prior to the use of this fuel for power generation. Scarcity of natural gas in systems where a share of electricity demand is supplied with gas ...
-
(Oxford University Press, 2020)Real-order generalization of dissipativeness and passivity concepts are presented in this paper. They are characterized as properties of a system; that is, they are independent of the system's internal representation and ...
-
(Elsevier, 2020)The temporal decay pattern of seismicity following rock bursts and large magnitude events is studied for aftershock sequences in several mines in Ontario, Canada. The decay phenomenon is described by the so – called Modified ...
