(Elsevier, 2016)We present a microeconomic model for time use and consumption for workers with an improved treatment of the (technical) relations between goods and time. In addition to the traditional time and income constraints, an ...
-
(IEEE-Inst Electrical Electronics Engineers, 2020)Absolute attitude estimation sensors provide high accuracy pointing capabilities to spacecraft, but as developed thus far, they constitute a large fraction of CubeSat mission’s budget. We introduce SPE Lab Open Star ...
-
(Springer Netherlands, 2018)This brief introduction is intended to orientate the reader with respect to the principal environmental and historical features of the Atacama Desert, the oldest and continuously driest non-polar temperate desert on Earth. ...
-
(IOP, 2020)Intermediate-mass black holes (IMBHs) have masses between 10(2) and 10(6) M<sub and are key to our understanding of the formation of massive black holes. The known population of IMBHs remains small, with a few hundred ...
-
(American Institute of Physics, 2020)This Focus Issue on instabilities and nonequilibrium structures includes invited contributions from leading researchers across many different fields. The issue was inspired in part by the “VII Instabilities and Nonequilibrium ...

-
(INFORMS, 2014)This special issue in mining presents surveys and applications. Specifically, in the former category, the issue contains a tutorial on open-pit mine-scheduling models, a literature review on equipment selection, and ...
-
(American Institute of Physics, 2011)Because scaling symmetries of the Euler–Lagrange equations are generally not variational symmetries of the action, they do not lead to conservation laws. Instead, an extension of Noether’s theorem reduces the equations ...
-
(Academic Press Inc., 2018)We give different conditions for the invariance of closed sets with respect to differential inclusions governed by a maximal monotone operator defined on Hilbert spaces, which is subject to a Lipschitz continuous perturbation ...
-
(Elsevier, 2020)In this article we present a new characterization of inverse M-matrices, inverse row diagonally dominant M-matrices and inverse row and column diagonally dominant M-matrices, based on the positivity of certain inner products.
-
(Springer, 2016)Moving average simulation can be summarized as a convolution between a spatial kernel and a white noise random field. The kernel can be calculated once the variogram model is known. An inverse approach to moving average ...
-
(Wiley-Blackwell, 2015)Honeycomb sandwich structures are used in a wide variety of applications. Nevertheless, because of manufacturing defects or impact loads, these structures can experience imperfect bonding or debonding between the skin and ...
-
(Wiley, 2022)Mathematical and computational modeling of the cardiovascular system is increasingly providing non-invasive alternatives to traditional invasive clinical procedures. Moreover, it has the potential for generating additional ...

-
(Association for Computing Machinery, 2017)We introduce a new representation of the inverted index that performs faster ranked unions and intersections while using similar space. Our index is based on the treap data structure, which allows us to intersect/merge the ...
-
Investigating Cepheid l Carinae' s cycle-to-cycle variations via contemporaneous velocimetry and ... (Oxford University Press, 2016)Baade-Wesselink-type (BW) techniques enable geometric distance measurements of Cepheid variable stars in the Galaxy and the Magellanic clouds. The leading uncertainties involved concern projection factors required to ...
-
(Elsevier Inc., 2019)Introduction: Apical periodontitis (AP) and cardiovascular diseases (CVDs) are chronic conditions triggered by an inflammatory process and sharing similar pathogeneses and molecular players. Previous studies have suggested ...
-
(Pergamon-Elsevier, 2020)The purpose of this work is to highlight the impact of input parameters uncertainty in discrete fracture network (DFN) models and their engineering applications. We show how the error of an input parameter, here the ...
-
(EDP, 2020)Context. Young stars interact with their accretion disk through their strong magnetosphere.Aims. We aim to investigate the magnetospheric accretion/ejection process in the young stellar system DoAr 44 (V2062 Oph).Methods. ...
-
(Copernicus Gesellschaft MBH, 2020)The rapid urbanization and industrialization of northern China in recent decades has resulted in poor air quality in major cities like Beijing. Transport of air pollution plays a key role in determining the relative influence ...
