Community detection in directed acyclic graphs [PDF]

The European Physical Journal B, 2015
Some temporal networks, most notably citation networks, are naturally represented as directed acyclic graphs (DAGs). To detect communities in DAGs, we propose a modularity for DAGs by defining an appropriate null model (i.e., randomized network) respecting the order of nodes.

The SIR Model in a Moving Population: Propagation of Infection and Herd Immunity

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT In a collection of particles performing independent random walks on Zd$\mathbb {Z}^d$ we study the spread of an infection with SIR dynamics. Susceptible particles become infected when they meet an infected particle. Infected particles heal and are removed at rate ν$\nu$.

A fast and efficient path elimination algorithm for large-scale multiple common longest sequence problems

BMC Bioinformatics, 2022
Background In various fields, searching for the Longest Common Subsequences (LCS) of Multiple (i.e., three or more) sequences (MLCS) is a classic but difficult problem to solve.

Early‐Life Exposures and Risk of Multiple Myeloma: A Population‐Based Case–Control Study in Australia

International Journal of Cancer, EarlyView.
Early‐life exposures may influence immune system development and, in turn, affect cancer susceptibility. In this population‐based case‐control study, the authors examined whether in utero or early childhood exposures were associated with the risk of developing multiple myeloma in adulthood.

Directed Acyclic Graph-Based Datapath Synthesis Using Graph Isomorphism and Gate Reconfiguration

Chips
Datapath synthesis is a crucial step in synthesis flow and aims at globally minimizing an area by identifying shareable logic structures. This paper introduces a novel Directed Acyclic Graph (DAG)-based datapath synthesis method based on graph ...

LCA Queries in Directed Acyclic Graphs [PDF]

, 2005
We present two methods for finding a lowest common ancestor (LCA) for each pair of vertices of a directed acyclic graph (dag) on n vertices and m edges. The first method is surprisingly natural and solves the all-pairs LCA problem for the input dag on n vertices and m edges in time O(nm). As a corollary, we obtain an O(n2)-time algorithm for finding

Association between annual twin delivery volume and severe postpartum hemorrhage in twin pregnancies

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To assess the association between the risk of severe postpartum hemorrhage (PPH) and the annual twin delivery volume of maternity units. Methods JUmeaux MODe d'Accouchement (JUMODA) was a national observational prospective population‐based cohort of twin deliveries in 176 French maternity units performing more than 1500 annual ...

A DAG Scheduling Scheme on Heterogeneous Computing Systems Using Tuple-Based Chemical Reaction Optimization

The Scientific World Journal, 2014
A complex computing problem can be solved efficiently on a system with multiple computing nodes by dividing its implementation code into several parallel processing modules or tasks that can be formulated as directed acyclic graph (DAG) problems. The DAG

Postpartum anemia and maternal wellbeing: A cohort analysis of the WOMAN‐2 trial

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We examined the association between postpartum anemia and maternal wellbeing in women who gave birth with anemia. Methods We conducted a cohort analysis using secondary data from the WOMAN‐2 trial. Between August 2019 and September 2023, women with moderate or severe anemia who were giving birth vaginally were recruited from ...
