Newton mechanics, Galilean relativity, and special relativity in $\alpha$-deformed binary operation setting

open access: yesSciPost Physics Proceedings, 2023
We define new velocity and acceleration having dimension of $(Length)^{\alpha}/(Time)$ and $(Length)^{\alpha}/(Time)^2,$ respectively, based on the fractional addition rule.

Theory of Gravity Dependent on Entropy

open access: yesReports in Advances of Physical Sciences, 2023
Gravitational redshift decreases the resolution of measurements, causing entropy by increasing the possible microstates of position and momentum for objects within a gravitational field.

Relativity and the Magnitude of Velocities

open access: yesScience and Technology Indonesia
In modern physics, relativity is primarily understood through the framework of Einstein’s theory. According to the special theory of relativity (STR), Galilean relativity serves as a very accurate approximation at low velocities, where ‘relativistic ...

Space and time in special relativity [PDF]

open access: yesRevista Brasileira de Ensino de Física
In this review of the kinematic part of Einstein’s Theory of Special Relativity, the physical meaning of the Lorentz Transformations is elucidated from basic physical facts that, although implicit in the formulation of the theory, are usually overlooked ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

A logic road from special to general relativity [PDF]

open access: yes, 2010
We present a streamlined axiom system of special relativity in firs-order logic. From this axiom system we ``derive'' an axiom system of general relativity in two natural steps.

Spatial Geometry and Special Relativity: a comparative approach

open access: yesRevista Brasileira de Ensino de Física
In this work, it is shown the interplay of relative and absolute entities, which are present in both spatial geometry and special relativity. In order to strengthen the understanding of special relativity, we discuss firstly an instance of geometry and ...

Discussions on Special and General Relativity Model

open access: yesChaos Theory and Applications, 2021
In this study, the Michelson–Morley experiment and the result of this experiment (the speed of light appears to be the same in all directions) were explored.

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

A logic road from special to general relativity [PDF]

open access: yes, 2012
We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we ``derive'' an axiom system of general relativity in two natural steps.
