Brans-dicke cosmology and the cosmological constant: The spectrum of vacuum solutions
We study the Brans-Dicke vacuum field equations in the presence of a cosmological term A. Considering a Friedmann-Robertson-Walker metric with flat spatial sections (k=0), we provide a qualitative analysis of the...

The equivalence between General Relativity and scalar-tensor theories of gravity
The equivalence between General Relativity and scalar-tensor theories is discussed. Vacuum solutions of the Brans-Dicke theory of gravity are shown to behave ambiguously whenever attempts are made to interpret...

Brans-dicke vacuum solutions and the cosmological constant: A qualitative analysis
We investigate Brans-Dicke vacuum solutions in the presence of a cosmological constant A from the point of view of dynamical system theory. Assuming a Friedmann-Robertson-Walker metric we plot the phase diagra...

Open AccessSeparation of track- and shower-like energy deposits in ProtoDUNE-SP using a convolutional neural network
Liquid argon time projection chamber detector technology provides high spatial and calorimetric resolutions on the charged particles traversing liquid argon. As a result, the technology has been used in a numb...

Open AccessReconstruction of interactions in the ProtoDUNE-SP detector with Pandora
The Pandora Software Development Kit and algorithm libraries provide pattern-recognition logic essential to the reconstruction of particle interactions in liquid argon time projection chamber detectors. Pandor...

A local rigidity theorem for minimal two-spheres in charged time-symmetric initial data set
The purpose of this article is to prove that, under suitable constraints on time-symmetric initial data set for the Einstein–Maxwell equation M, if ...
