(Springer, 2023)In Stackelberg security games, a leader locates security resources to protect a set of targets from strategic adversaries that aim to attack these targets after observing the leader’s strategy. In this setting, the leader ...
-
(2016)Location privacy is a concern in mobile networks monitoring systems. We propose a model using homomorphic encryption, where researchers can compute aggregations, learning nothing more about users' location than the result ...
-
(Nature Research, 2021)As the novel coronavirus (COVID-19) pandemic spread across the world over the past year, many countries imposed lockdowns in the form of stay at home requirements on their citizens to mitigate its spread. We analyze mobility ...
-
(Oxford University Press, 2016)We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 ...
-
(Oxford University Press, 2018-07)Galaxy clusters are expected to form hierarchically in a Lambda cold dark matter (Lambda CDM) universe, growing primarily through mergers with lower mass clusters and the continual accretion of group-mass haloes. Galaxy ...
-
(IOP Publishing, 2015)We present a study of the spatial distribution and kinematics of star-forming galaxies in 30 massive clusters at 0.15 < z < 0.30, combining wide-field Spitzer 24 mu m and GALEX near-ultraviolet imaging with highly complete ...
-
(Springer, 2013)We prove that under n1/3 scaling, the limiting distribution as n → ∞of the free energy of Seppäläinen’s log-Gamma discrete directed polymer is GUE Tracy- Widom. The main technical innovation we provide is a general ...
-
(Elsevier, 2013)The identification of seismic records in seismically active mines is examined by considering logistic regression and neural network classification techniques. An efficient methodology is presented for applying these ...
-
(Universidad de Chile, 2019)El presente documento resume el desarrollo de una investigación conducente al grado de Doctor en Sistemas de Ingeniería, Universidad de Chile. Se presenta un análisis exhaustivo de 178 artículos, incluyendo estudios en ...
-
(Universidad de Chile, 2021)El Ecuador en los últimos años ha llevado a cabo una política de gasto expansiva con un presupuesto anual por sobre los USD 34.000 millones, los cuales se financian principalmente por impuestos - tasas, y financiamiento ...
-
(Universidad de Chile, 2017)El Yacimiento Los Sulfatos (Anglo American), distrito Río Blanco - Los Bronces, es un depósito tipo pórfido cuprífero de clase mundial ubicado a 50 km al noreste de Santiago, Chile central. Presenta mineralización de cobre ...
-
(IOP, 2020)Using the Atacama Large Millimeter/submillimeter Array, we observed the young Herbig star HD 100546, host to a prominent disk with a deep, wide gap in the dust. The high-resolution 1.3 mm continuum observation reveals fine ...

-
(E D P SCIENCES, 7, AVE DU HOGGAR, PARC D ACTIVITES COURTABOEUF, 2004)We present the kinematical data obtained for a sample of active (Seyfert) and non active isolated spiral galaxies, based on long slit spectra along several position angles in the Hα line region and, in some cases, in the ...
-
(Springer, 2017)A fluid queuing network constitutes one of the simplest mod-els in which to study flow dynamics over a network. In this model wehave a single source-sink pair and each link has a per-time-unit capac-ity and a transit time. ...
-
(2016)We study the long-time behavior of variants of the telegraph process with position-dependent jump rates, which result in a monotone gradient-like drift towards the origin. We compute their invariant laws and obtain, via ...
-
(2010)The Doppler wobble induced by the extra-solar planet HD 134987b was first detected by data from the Keck Telescope nearly a decade ago, and was subsequently confirmed by data from the Anglo-Australian Telescope (AAT). ...
-
(Mosby Inc., 2019)Introduction: Laparoscopic Nissen fundoplication is the preferred operative treatment for patients with gastroesophageal reflux disease. The most recent published results only refer to clinical evaluations and few discuss ...
-
(Universidad de Chile, 2015)América Central, América del Sur y el Caribe destacan en el escenario energético mundial por la contribución espectacular de las fuentes renovables en la matriz energética regional. Mantener tal participación en el futuro ...
-
(American Society of Civil Engineers, 2014)Repetitive loading can induce volumetric and shear strain accumulation in soils and affect the long-term performance of engineered and natural geosystems.Ahybrid numerical scheme based on theFEMis implemented to analyze ...
