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.

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

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

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,

Non-locality and causal evolution in QFT [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2006
Non locality appearing in QFT during the free evolution of localized field states and in the Feynman propagator function is analyzed. It is shown to be connected to the initial non local properties present at the level of quantum states and then it does not imply a violation of Einstein's causality.

Causal Discovery Under Local Privacy

open access: yesCoRR, 2023
Differential privacy is a widely adopted framework designed to safeguard the sensitive information of data providers within a data set. It is based on the application of controlled noise at the interface between the server that stores and processes the data, and the data consumers.

Childhood Acute Lymphoblastic Leukemia Survival in Western Kenya: Reduction in Early Deaths and Treatment Abandonment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background An earlier study on children diagnosed with acute lymphoblastic leukemia (ALL) at Moi Teaching and Referral Hospital (MTRH) in Kenya reported a low event‐free survival (EFS), excess treatment abandonment, and high induction mortality.

Causal Structural Learning via Local Graphs

open access: yesSIAM Journal on Mathematics of Data Science, 2023
We consider the problem of learning causal structures in sparse high-dimensional settings that may be subject to the presence of (potentially many) unmeasured confounders, as well as selection bias. Based on the structure found in common families of large random networks and examining the representation of local structures in linear structural equation

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 ...
