Possible Simple Structures of the Universe to Include General Relativity Effects [PDF]

open access: yesINCAS Bulletin, 2017
The general relativity describes the universe properties, the gravity playing a fundamental role. One uses a metric tensor in a Riemann space, g  , which should be in agreement with a mass (or energy) tensor in order to satisfy the Einstein equation of

The impact of radiotherapy on the hypothalamo-pituitary axis: old vs new radiotherapy techniques

open access: yesEndocrine Connections, 2023
Multimodality cancer therapy has led to remarkable improvements in survival of childhood and young adult cancer, with survival rates exceeding 85%. Such remission rates come with their own adverse sequelea or ‘late effects’.

Power-effective integral thermoelectric solar radiation converter

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2020
Aim. This article is devoted to the conversion of solar radiation into electricity using the joint effect of several methods, which complement each other by transforming the disadvantages of one method into the advantages of another method. Methods. Heat

THE INERTIA OF LIGHT. VERIFICATION OF NEWTON’S SECOND LAW BY ACONFINED FLOW OF RADIATION IN A REFLECTIVE CAVITY

open access: yesAnales (Asociación Física Argentina), 2023
In 1904, the Austrian physicist Fritz Hasenöhrl examined by means of mental experiments the black body radiation in a reflecting cavity. By calculating the work required to keep the cavity moving at constant velocity in opposition to the radiation ...

Photon number conservation and photon interference [PDF]

open access: yes, 2001
The group theoretical aspect of the description of passive lossless optical four-ports (beam splitters) is revisited. It is shown through an example, that this approach can be useful in understanding interferometric schemes where a low number of photons ...

HIGH ENERGY PHOTON-PHOTON AND ELECTRON-PHOTON COLLISIONS [PDF]

open access: yesInternational Journal of Modern Physics A, 1998
The advent of a next linear e±e- collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ*γ*→X in the region dominated by BFKL hard Pomeron exchange and report the ...

On the Remarkable Features of the Lower Limits of Charge and the Radiated Energy of Antennas as Predicted by Classical Electrodynamics

open access: yesAtmosphere, 2016
Electromagnetic energy radiated by antennas working in both the frequency domain and time domain is studied as a function of the charge associated with the current in the antenna.

Kerr-Nonlinearity-Triggered Nonclassicality of Magnons in a Photon-Magnon Coupling System

open access: yesPhotonics, 2022
Hybrid quantum systems have attracted much attention due to the fact that they combine the advantages of different physical subsystems. Cavity QED (cavity quantum electrodynamics) with magnons is a hybrid quantum systems that combines a YIG (Yttrium Iron
