Bell’s Theorem Versus Local Realism in a Quaternionic Model of Physical Space

open access: yesIEEE Access, 2019
In the context of EPR-Bohm type experiments and spin detections confined to spacelike hypersurfaces, a local, deterministic and realistic model within a Friedmann-Robertson-Walker spacetime with a constant spatial curvature (S3) is presented that ...

Identifying interactions in the time and frequency domains in local and global networks : a Granger causality approach [PDF]

open access: yes, 2010
Background Reverse-engineering approaches such as Bayesian network inference, ordinary differential equations (ODEs) and information theory are widely applied to deriving causal relationships among different elements such as genes, proteins, metabolites,

Closing the Door on Quantum Nonlocality

open access: yesEntropy, 2018
Bell-type inequalities are proven using oversimplified probabilistic models and/or counterfactual definiteness (CFD). If setting-dependent variables describing measuring instruments are correctly introduced, none of these inequalities may be proven.

Employment impact of national, provincial and local government capital in South Africa: An aggregate and sectoral perspective

open access: yesCogent Economics & Finance, 2022
This study examines the impact of general/national, provincial and local government capital on employment in South Africa. The study spans from 1993 to 2017 for a panel of 269 South African municipalities. The study employs the Granger causality test and

Causal relationship between sea surface temperature and precipitation revealed by information flow

open access: yesFrontiers in Climate, 2022
The atmosphere and the ocean are coupled with each other through various processes. Therefore, it is of great importance to understand the causality relationship between the atmosphere and the ocean for predicting their states.

Modeling the Arrows of Time with Causal Multibaker Maps

open access: yesEntropy
Why do we remember the past, and plan the future? We introduce a toy model in which to investigate emergent time asymmetries: the causal multibaker maps. These are reversible discrete-time dynamical systems with configurable causal interactions. Imposing

Quantitative Approaches for Causality Assessment of Adverse Events Following Immunisation for COVID-19 Vaccines

open access: yesVaccine Research, 2021
Vaccine safety surveillance is important to identify and manage adverse events following immunisation (AEFI) and avoid vaccine hesitancy. Currently, COVID-19 vaccines are administered to large numbers of people to try and curb the pandemic. In this paper,

Stochastic Einstein Locality Revisited [PDF]

open access: yes, 2007
I discuss various formulations of stochastic Einstein locality (SEL), which is a version of the idea of relativistic causality, i.e. the idea that influences propagate at most as fast as light.

Causality between challenges, availability, and extent of use of local building materials

open access: yesSouth African Journal of Science, 2022
The promotion of sustainable practice in construction has resulted in a renewed focus on local building materials (LBMs). However, existing studies have not provided an extensive understanding of the challenges in the use and awareness of the ...
