Supremica – An integrated environment for verification, synthesis and simulation of discrete event systems [PDF]

open access: yes, 2006
An integrated environment, Supremica, for verification, synthesis and simulation of discrete event systems is presented. The basic model in Supremica is finite automata where the transitions have an associated event together with a guard condition and an

Asymmetric Whisker‐Inspired Sensor Pairs for Enhanced Airflow Sensing on Drones

open access: yesAdvanced Intelligent Systems, EarlyView.
This work incorporates asymmetric cross‐sections into a whisker‐inspired sensor pair to enhance airflow sensing. By comparing signals between two offset asymmetric whiskers, the system improves flow heading estimation and identifies the presence of fan‐generated wind during quadrotor flight.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Place‐based risk: Examining relationships between adolescent perceptions of community risk factors and adolescent substance use across geographic contexts

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Mixed evidence for the influence of structural and social factors on adolescent substance use behaviors exists across the rural–urban continuum. Therefore, this study explores how adolescent perceptions of structural and social community risk factors are associated with lifetime and past 30‐day use of alcohol, marijuana, cigarettes, and ...

Mollification along the Coarse Scale Flow

open access: yes, 2017
This chapter shows how to construct the appropriate mollification of the Reynolds stress along the coarse scale flow. Unlike the velocity field, which was only mollified in the spatial variables and which earned its time-regularity through the Euler ...

Discrete Exterior Calculus [PDF]

open access: yes, 2003
This thesis presents the beginnings of a theory of discrete exterior calculus (DEC). Our approach is to develop DEC using only discrete combinatorial and geometric operations on a simplicial complex and its geometric dual.

Intensified Manufactured Non‐Belonging: Working Holiday Makers in Australia During the COVID‐19 Pandemic

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Nations manufacture non‐belonging of temporary migrants through policy frameworks that produce exclusion. This precarity maximises the economic benefit of temporary migrant labour by minimising their political, social and legal rights. In this paper, we examine how non‐belonging targeting Working Holiday Makers (WHMs) is manufactured in ...

Discrete Tracy--Widom operators. [PDF]

open access: yes, 2009
Integrable operators arise in random matrix theory, where they describe the asymptotic eigenvalue distribution of large self-adjoint random matrices from the generalized unitary ensembles.

A Comparison of Frailty Indices in Predicting Postoperative Outcomes After Endoscopic Sinus Surgery

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective To compare the discriminatory performance of the Risk Analysis Index (RAI) and modified Frailty Index‐5 (mFI‐5) in predicting postoperative outcomes following endoscopic sinus surgery (ESS). Study Design Retrospective cohort study. Methods Adult ESS patients were identified from the ACS‐NSQIP database (2005–2020).
