On the dynamics of the general Bianchi IX spacetime near the singularity
European Physical Journal C: Particles and Fields, 2018 We show that the complex dynamics of the general Bianchi IX universe in the vicinity of the spacelike singularity can be approximated by a simplified system of equations. Our analysis is mainly based on numerical simulations.

Averaging generalized scalar field cosmologies IV: locally rotationally symmetric Bianchi V model
European Physical Journal C: Particles and FieldsThis research focuses on scalar field cosmologies with a generalized harmonic potential. Our attention is centred on the anisotropic LRS Bianchi I and III metrics, Bianchi V metrics, and their isotropic limits.

The deceleration parameter in perturbed Bianchi universes with a peculiar-velocity “tilt”
European Physical Journal C: Particles and FieldsBianchi cosmologies are “natural” anisotropic extensions of the Friedmann universes and they have long been used to investigate the cosmological implications of anisotropy.

Perfect fluid Bianchi cosmological model admitting conformal motions in f(Q, T) gravity
Nuclear Physics BIn this paper, we intend to explore Conformal Vector Fields (CVFs) of the Locally Rotationally Symmetric (LRS) Bianchi type-I cosmological model within the setup of f(Q, T) gravity, where Q denotes the non-metricity scalar and T is the trace of stress ...

Redshift Cosmológico en un Modelo Bianchi I Axisimétrico: Análisis Cualitativo
Revista Politécnica, 2017 Resumen: Dado que la evidencia de las anomalías de la Radiación Cósmica de Fondo sugiere que el Universo esligeramente anisótropo, el planteamiento de un Modelo Cosmológico alternativo al modelo que cumple el Principio Cosmológico es necesario.

On non-BPS effective actions of string theory
European Physical Journal C: Particles and Fields, 2018 We discuss some physical prospective of the non-BPS effective actions of type IIA and IIB superstring theories. By dealing with all complete three and four point functions, including a closed Ramond–Ramond string (in terms of both its field strength and ...

Assessment of Tumor Vascularization: Immunohistochemical and Non-Invasive Methods
The International Journal of Biological Markers, 1999 Growth of solid tumors beyond a certain mass is dependent on the vascular bed from pre-existing host vasculature. The process of angiogenesis is essential not only for primary tumor growth but also for metastasis.
