Perfect fluid Bianchi cosmological model admitting conformal motions in f(Q, T) gravity

open access: yesNuclear Physics B
In 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 ...

Sequelae of child maltreatment: Umbrella synthesis of 148 meta‐analyses on the mental health correlates

open access: yesJCPP Advances, EarlyView.
Our umbrella synthesis found strong, often equivalent, associations between child maltreatment and all examined mental health difficulties. Different types of maltreatment appear to have comparably negative effects on mental health. If replicated, these findings may cause us to reconsider conventional wisdom that suggests some forms of CM are less ...

Redshift Cosmológico en un Modelo Bianchi I Axisimétrico: Análisis Cualitativo

open access: yesRevista 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.

Internationalization, Dynamic Capabilities, and Innovation: Unveiling the Impact on Hotel Chain Performance

open access: yesStrategic Change, EarlyView.
ABSTRACT The indirect effect of dynamic capabilities on performance has recently emerged as a topic of significant interest and debate in management research. In turbulent environments such as the international hotel industry, where companies constantly innovate to improve their performance, it is important to consider the effect of these dynamic ...

Association Between Colorectal Cancer Screening and Survival in Patients Older Than 70 Years: Results of A National Multicenter Retrospective Study

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background Colorectal cancer screening mainly targets a population between 50 and 70 years of age; however, it is inconsistently implemented in people over 70. The aim of this study was to analyze the association between colorectal cancer (CRC) screening, postoperative mortality, and perioperative and oncologic outcomes in a large population ...

On non-BPS effective actions of string theory

open access: yesEuropean 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 ...

Outcomes and Innervation of Gracilis for Pediatric Facial Paralysis: A Systematic Review

open access: yesThe Laryngoscope, EarlyView.
This systematic review compares innervation techniques for gracilis free muscle transfer in pediatric facial paralysis. Masseteric innervation produced the greatest commissure excursion, cross‐facial nerve grafting enabled spontaneous smiles, and dual innervation balanced both with high satisfaction and low complication rates across techniques ...

On Non‐Compact Extended Bach Solitons

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We study the characterization of non‐compact solitons of the extended Bach flow, known as an extended Bach soliton. We prove that a weakly conformally flat extended Bach soliton (Mn,g,V)$(M^n,g,V)$ with harmonic Weyl tensor is Bach‐flat and the potential vector field V$V$ is conformal.
