Journal of Graph Algorithms and Applications
In an upward-planar L-drawing of a directed acyclic graph (DAG) each edge $e=(v,w)$ is represented as a polyline composed of a vertical segment with its lowest endpoint at the tail $v$ of $e$ and of a horizontal segment ending at the head $w$ of $e ...

Pedo‐Climatic Controls on Soil Health Recovery Across Cultivation Chronosequences: Hydraulic Conductivity as a Potential Link Between Soil Structure, Microbial Biomass, and Nutrient Availability

Land Degradation &Development, EarlyView.
ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

Creating Minimal Vertex Series Parallel Graphs from Directed

, 2008
Visualizing information whose underlying graph is directed acyclic is easier if the graph is Minimal Vertex Series Parallel (MVSP). We present method of transforming any directed acyclic graph into one that is MVSP.

Directed Acyclic Graph Convolutional Networks

IEEE Transactions on Signal Processing
Directed acyclic graphs (DAGs) are central to science and engineering applications including causal inference, scheduling, and neural architecture search. In this work, we introduce the DAG Convolutional Network (DCN), a novel graph neural network (GNN) architecture designed specifically for convolutional learning from signals supported on DAGs.

Mind the Gap: Predictors of Osteoporosis Treatment Following Fragility Fracture in Parkinsonism

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Fracture risk is increased in Parkinson's yet this risk is often not addressed. Objectives Our objective was to study the extent to which osteoporosis was treated, and predictors of treatment in a large representative cohort with parkinsonism.

Mapping Causal Biology: Mendelian Randomization in the Era of Big Data

Med Research, EarlyView.
Mendelian randomization (MR) leverages genetic variants to mitigate confounding biases in causal inference. This review systematically maps MR's methodological evolution, highlights its expanding applications in epidemiology and drug target validation, and outlines future directions for overcoming current biases through dynamic, multi‐omics, and cross ...

Inference of k-testable directed acyclic graph languages [PDF]

, 2012
In this paper, we tackle the task of graph language learning. We first extend the well-known classes of k-testability and k-testability in the strict sense languages to directed graph languages.
