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 ...

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.

Jamming non-local quantum correlations [PDF]

open access: yes, 1995
We present a possible scheme to tamper with non-local quantum correlations in a way that is consistent with relativistic causality, but goes beyond quantum mechanics.

Minimal Assumption Derivation of a weak Clauser-Horne Inequality [PDF]

open access: yes, 2006
According to Bell's theorem a large class of hidden-variable models obeying Bell's notion of local causality conflict with the predictions of quantum mechanics.

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

Re-thinking local causality [PDF]

open access: yesSynthese, 2014
There is widespread belief in a tension between quantum theory and special relativity, motivated by the idea that quantum theory violates J. S. Bell's criterion of local causality, which is meant to implement the causal structure of relativistic space-time.

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.

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,

Under-approximating Cut Sets for Reachability in Large Scale Automata Networks [PDF]

open access: yes, 2013
In the scope of discrete finite-state models of interacting components, we present a novel algorithm for identifying sets of local states of components whose activity is necessary for the reachability of a given local state.
