Uniqueness of radiomic features in non‐small cell lung cancer
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose The uniqueness of radiomic features, combined with their reproducibility, determines the reliability of radiomic studies. This study is to test the hypothesis that radiomic features extracted from a defined region of interest (ROI) are unique to the underlying structure (e.g., tumor). Approach Two cohorts of non‐small cell lung cancer (

Colloquium : Fractional electromagnetism in quantum matter and high-energy physics [PDF]
Reviews of Modern Physics, 2019 We present here a theory of fractional electro-magnetism which is capable of describing phenomenon as disparate as the non-locality of the Pippard kernel in superconductivity and anomalous dimensions for conserved currents in holographic dilatonic models.

New physics from high energy tops [PDF]
Journal of High Energy Physics, 2018 A bstractPrecision measurements of high energy top quarks at the LHC constitute a powerful probe of new physics. We study the effect of four fermion operators involving two tops and two light quarks on the high energy tail of the tt¯$$ t\overline{t ...

New Physics and the Landau Pole [PDF]
, 2000 In scalar field theories the Landau pole is an ultraviolet singularity in the running coupling constant that indicates a mass scale at which the theory breaks down and new physics must intervene.

Systematic Analysis of the Non-Extensive Statistical Approach in High Energy Particle Collisions - Experiment vs. Theory [PDF]
Entropy, 2017 The analysis of high-energy particle collisions is an excellent testbed for the non-extensive statistical approach. In these reactions we are far from the thermodynamical limit. In small colliding systems, such as electron-positron or nuclear collisions,

Fundamental constants and their variability in theories of high energy physics [PDF]
The European Physical Journal Special Topics, 2008 The Standard Model of particle physics and the theory of General Relativity (GR) currently provide a good description of almost all phenomena of particle physics and gravitation that have received controlled experimental tests. However, the Standard Model contains many a priori variable parameters whose values, and whose apparent (near-)constancy, have

Self-similar interpolation in high-energy physics [PDF]
, 2015 A method is suggested for interpolating between small-variable and large-variable asymptotic expansions. The method is based on self-similar approximation theory resulting in self-similar root approximants.

High energy physics signatures from inflation and conformal symmetry of de Sitter [PDF]
, 2015 During inflation, the geometry of spacetime is described by a (quasi‐)de Sitter phase. Inflationary observables are determined by the underlying (softly broken) de Sitter isometry group SO(1,4) which acts like a conformal group on R3 : when the ...
