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$\nu$.

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

Clinical Pharmacology &Therapeutics, EarlyView.Despite the immunomodulatory mechanism of immune checkpoint inhibitors (ICIs), systemic glucocorticoids are commonly used in advanced non–small cell lung cancer (NSCLC). Evidence regarding their effects on ICI outcomes is inconsistent, in part due to confounding by indication and immortal time bias.

Cohesive Motion Control Algorithm for Formation of Multiple Autonomous Agents
Journal of Robotics, 2010 This paper presents a motion control strategy for a rigid and constraint consistent formation that can be modeled by a directed graph whose each vertex represents individual agent kinematics and each of directed edges represents distance constraints ...

Clinical Pharmacology &Therapeutics, EarlyView.Pain and fever are common in pregnancy. Dipyrone is widely used in Europe, Latin America, and parts of Asia, but is banned in other countries due to concerns about agranulocytosis. Evidence on its safety in pregnancy remains limited and inconsistent. This study aimed to evaluate whether maternal dipyrone use during the first‐ and third‐trimesters is ...

Dynamic Economic Relationships Among U.S. Soy Product Markets: Using a Cointegrated Vector Autoregression Approach with Directed Acyclic Graphs [PDF]
This paper applies a combined methodology of a recently developed directed acyclic graph (DAG) analysis with Johansen and Juselius' methods of the cointegrated vector autoregression (VAR) model to a monthly U.S.
