In this paper, the model of radial motion of dusty matter for the spherically symmetric case in General Relativity (GR) was developed. The model can be used, in particular, to describe galactic halos of dark matter. The ...

ABSTRACT Tensism is the view that tense is not merely a property of language and the mind (narrowly individuated), but of the world itself. Perspectivalism extends this idea to all perspectival properties be they person ...

We propose an extended General Relativistic formalism with boundary terms included, that describes the dynamics of quantum spinor fields, which can take intermediate values, named (3 + 1) -anyons. In the approach here wo...

We calculate the algebra of constraints for deparametrized general relativity with a space-time filling unstable D-brane for an arbitrary value of tachyon field T. We also propose observables that have vanishing Poisson ...

Relativity theory severely restricts the ability to perform nonlocal measurements in quantum mechanics. Studying such nonlocal schemes may thus reveal insights regarding the relations between these two fundamental theori...

Abstract Physiological interpretations of Systems Biology have made many advances since the Principles of Systems Biology were first published in this journal in 2008. Those advances show that the main principle, Biologi...

We introduce a new scheme based on the marked correlation function to probe gravity using the large-scale structure of the Universe. We illustrate our approach by applying it to simulations of the metric-variation f(R) m...

We present a study of the so called relaxed field equations of general relativity in terms of a decomposition of the metric; which is designed to deal with the notion of particles. Several known results are generalized t...

Foram avaliados os principais índices diastólicos, inclusive a velocidade de propagação mitral (Vp), em 36 cães sadios da raça Boxer, 18 de cada sexo, de idade entre um ano e meio e seis anos. A relação raiz aór...

Understanding the nature of the interaction between the lead(II) ion, Pb2+, and water molecules is crucial to describe the stability and chemical behaviour of structures formed during solvation, as well as theconditions ...

Abstract We investigate the cosmological implications of an extended gravitational framework based on biconnection gravity, constructed from the Schr $$\ddot{\textrm{o}}$$ o ¨ dinger connection and its dual. In this app...

The present paper aims at testing a model to predict personal involvement with a social object which was inspired by the social psychological triangle proposed by Moscovici. The triangle bridges three essential aspects o...

A física, como prática filosófica, designa a escolha de ângulo de abordagem sob o qual é possível perceber características fundamentais da física. Assumimos que os papéis do físico e do filósofo não são tão...

We report the formation of a soliton—termed “event soliton”—in nonlinear photonic spacetime crystals (STCs). In these media, simultaneous spatiotemporal periodic modulation of the dielectric constant generates mi...
