The Algebra of Directed Acyclic Graphs [PDF]
, 2013 We give an algebraic presentation of directed acyclic graph structure, introducing a symmetric monoidal equational theory whose free PROP we characterise as that of finite abstract dags with input/output interfaces.

Qualitative Approximations to Causality: Non-Randomizable Factors in Clinical Psychology
Clinical Psychology in Europe, 2021 [Background] Causal quests in non-randomized studies are unavoidable just because research questions are beyond doubt causal (e.g., aetiology). Large progress during the last decades has enriched the methodical toolbox. [Aims] Summary papers mainly focus

A directed acyclic graph for interactions [PDF]
International Journal of Epidemiology, 2020 Abstract Background Directed acyclic graphs (DAGs) are of great help when researchers try to understand the nature of causal relationships and the consequences of conditioning on different variables.

Statistical tests for associations between two directed acyclic graphs.
PLoS ONE, 2010 Biological data, and particularly annotation data, are increasingly being represented in directed acyclic graphs (DAGs). However, while relevant biological information is implicit in the links between multiple domains, annotations from these different ...

Decision-theoretic foundations for statistical causality: Response to Pearl
Journal of Causal Inference, 2022 I thank Judea Pearl for his discussion of my paper and respond to the points he raises. In particular, his attachment to unaugmented directed acyclic graphs has led to a misapprehension of my own proposals. I also discuss the possibilities for developing

Broadcasting on Random Directed Acyclic Graphs
, 2020 We study a generalization of the well-known model of broadcasting on trees. Consider a directed acyclic graph (DAG) with a unique source vertex $X$, and suppose all other vertices have indegree $d\geq 2$.

Causal Inference Analysis for Poorly Soluble Low Toxicity Particles, Lung Function, and Malignancy
Frontiers in Public Health, 2022 Poorly soluble low toxicity particles such as carbon black and titanium dioxide have raised concern about possible nonmalignant and malignant pulmonary effects. This paper illustrates application of causal inference analysis to assessing these effects. A

Throughput-Optimal Broadcast on Directed Acyclic Graphs [PDF]
, 2014 We study the problem of broadcasting packets in wireless networks. At each time slot, a network controller activates non-interfering links and forwards packets to all nodes at a common rate; the maximum rate is referred to as the broadcast capacity of ...

Upward Three-Dimensional Grid Drawings of Graphs [PDF]
, 2005 A \emph{three-dimensional grid drawing} of a graph is a placement of the vertices at distinct points with integer coordinates, such that the straight line segments representing the edges do not cross. Our aim is to produce three-dimensional grid drawings
