Scalar field cosmologies with inverted potentials [PDF]

Journal of Cosmology and Astroparticle Physics, 2015
Regular bouncing solutions in the framework of a scalar-tensor gravity model were found in a recent work. We reconsider the problem in the Einstein frame (EF) in the present work. Singularities arising at the limit of physical viability of the model in the Jordan frame (JF) are either of the Big Bang or of the Big Crunch type in the EF.

Argumentando sobre a realidade dos potenciais

Revista Brasileira de Ensino de Física
Argumenta-se que, da mesma forma que o efeito Aharonov-Bohm mostrou ser o potencial vetor detetável microscopicamente, os nossos transformadores parecem indicar que ele o é macroscopicamente através de sua derivada temporal.

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Massive scalar counterpart of gravitational waves in scalarized neutron star binaries

European Physical Journal C: Particles and Fields, 2017
In analogy with spontaneous magnetization of ferromagnets below the Curie temperature, a neutron star (NS), with a compactness above a certain critical value, may undergo spontaneous scalarization and exhibit an interior nontrivial scalar configuration ...

Long-Range Scalar Forces in Five-Dimensional General Relativity

Advances in Mathematical Physics, 2020
We present new results regarding the long-range scalar field that emerges from the classical Kaluza unification of general relativity and electromagnetism.

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

Effective potential of scalar Lee-Wick pseudo-electrodynamics

Physics Letters B
The study of effective potential for the scalar Lee-Wick pseudo-electrodynamics in one-loop is presented in this letter. The planar and non-local Lee-Wick pseudo-electrodynamics is so coupled to a complex scalar field sector in 1+2 dimensions, where we ...

ON THE DYNAMICS OF A QUADRATIC SCALAR FIELD POTENTIAL [PDF]

International Journal of Modern Physics D, 2009
We review the attractor properties of the simplest chaotic model of inflation, in which a minimally coupled scalar field is endowed with a quadratic scalar potential. The equations of motion in a flat Friedmann–Robertson–Walker universe are written as an autonomous system of equations, and the solutions of physical interest appear as critical points ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
