Information geometry in quantum field theory: lessons from simple examples

open access: yesSciPost Physics, 2020
Motivated by the increasing connections between information theory and high-energy physics, particularly in the context of the AdS/CFT correspondence, we explore the information geometry associated to a variety of simple systems. By studying their Fisher

Fisher Fixed Point Results in Generalized Metric Spaces with a Graph

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2020
We discuss Fisher’s fixed point theorem for mappings defined on a generalized metric space endowed with a graph. This work should be seen as a generalization of the classical Fisher fixed point theorem.

The Fisher–Rao Distance between Multivariate Normal Distributions: Special Cases, Bounds and Applications

open access: yesEntropy, 2020
The Fisher–Rao distance is a measure of dissimilarity between probability distributions, which, under certain regularity conditions of the statistical model, is up to a scaling factor the unique Riemannian metric invariant under Markov morphisms.

Perceptual Scales Predicted by Fisher Information Metrics

open access: yes, 2023
Perception is often viewed as a process that transforms physical variables, external to an observer, into internal psychological variables. Such a process can be modeled by a function coined perceptual scale. The perceptual scale can be deduced from psychophysical measurements that consist in comparing the relative differences between stimuli (i.e ...

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Hybrid Fixed Point Theorem with Applications to Forced Damped Oscillations and Infinite Systems of Fractional Order Differential Equations

open access: yesJournal of Function Spaces, 2020
In this manuscript, hybrid common fixed point results in the setting of a b-metric space are established. Our results generalized the results of Fisher, Khan, and Piri et al. for set-valued mapping in b-metric spaces.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Holographic entanglement entropy, subregion complexity and Fisher information metric of ‘black’ non-susy D3 brane

open access: yesPhysics Letters B, 2020
The BPS D3 brane has a non-supersymmetric cousin, called the non-susy D3 brane, which is also a solution of type IIB string theory. The corresponding counterpart of black D3 brane is the ‘black’ non-susy D3 brane and like the BPS D3 brane, it also has a ...

Fisher-like Metrics Associated with ϕ-Deformed (Naudts) Entropies

open access: yesMathematics, 2022
The paper defines and studies new semi-Riemannian generalized Fisher metrics and Fisher-like metrics, associated with entropies and divergences. Examples of seven such families are provided, based on exponential PDFs.
