Euclid preparation. XLIV. Modelling spectroscopic clustering on mildly nonlinear scales in beyond-LCDM models [PDF]

open access: yesAstronomy & Astrophysics, 2023
The space satellite mission will measure the large-scale clustering of galaxies at an unprecedented precision, providing a unique probe of modifications to the Lambda CDM model.

Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS [PDF]

open access: yesAstronomy & Astrophysics, 2023
DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend from 74 to 84 AU from the central star. The high photometric precision of

A general form of the weak maximum principle and some applications [PDF]

open access: yes, 2013
The aim of this paper is to introduce new forms of the weak and Omori-Yau maximum principles for linear operators, notably for trace type operators, and show their usefulness, for instance, in the context of PDE's and in the theory of hypersurfaces.

“TNOs are Cool”: A survey of the trans-Neptunian region - X. Analysis of classical Kuiper belt objects from Herschel and Spitzer observations [PDF]

open access: yes, 2014
Context. The Kuiper belt is formed of planetesimals which failed to grow to planets and its dynamical structure has been affected by Neptune. The classical Kuiper belt contains objects both from a low-inclination, presumably primordial, distribution and ...

A Conflict-Resilient Lock-Free Calendar Queue for Scalable Share-Everything PDES Platforms [PDF]

open access: yes, 2017

A fine-grain time-sharing Time Warp system [PDF]

open access: yes, 2017
Although Parallel Discrete Event Simulation (PDES) platforms relying on the Time Warp (optimistic) synchronization protocol already allow for exploiting parallelism, several techniques have been proposed to further favor performance.

Sparse recovery in bounded Riesz systems with applications to numerical methods for PDEs [PDF]

open access: yes, 2020
We study sparse recovery with structured random measurement matrices having independent, identically distributed, and uniformly bounded rows and with a nontrivial covariance structure.

Maximum principle for state-constrained optimal control problems governed by quasilinear elliptic

open access: yesDifferential and Integral Equations, 1995
In this paper, the authors study an optimal control problem for quasilinear elliptic PDEs with pointwise state constraints. Weak and strong optimality conditions of Pontryagin maximum principle type are derived. In proving these results, we penalized the

A load-sharing architecture for high performance optimistic simulations on multi-core machines [PDF]

open access: yes, 2012
In Parallel Discrete Event Simulation (PDES), the simulation model is partitioned into a set of distinct Logical Processes (LPs) which are allowed to concurrently execute simulation events.

Programming agent-based demographic models with cross-state and message-exchange dependencies: A study with speculative PDES and automatic load-sharing [PDF]

open access: yes, 2016
Agent-based modeling and simulation is a versatile and promising methodology to capture complex interactions among entities and their surrounding environment.
