We created a deterministic, frequency-based model of the evolution of resistance by corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), to insecticidal traits expressed in crops planted in the heterogeneous landscapes of the southern United States. The model accounts for four generations of selection by insecticidal traits each year. We used the model results to investigate the inf...

This paper reports results of a study of reference models for representing open system environments (infrastructures). One of the issues considered in this paper is how to compare particular reference models known in the literature. We propose a set of features of reference models on which to base such comparisons. We have found that in some cases, due to the ambiguity of definitions, it is dif...

INTRODUCTION Biocompatibility is a desirable feature for root-end filling materials. In this study we aimed to compare a new material called cold ceramic (CC) with intermediate restorative material (IRM) and mineral trioxide aggregate (MTA) using Methyl-tetrazolium bromide (MTT) assay. MATERIALS AND METHODS The materials were tested in fresh and set states: (n=108). The cytotoxicity was compa...

This paper describes the SCYLLARUS approach to fusing reports from multiple intrusion detection systems (IDSes) to provide an overall approach to intrusion situation awareness. The overall view provided by SCYLLARUS centers around the site’s security goals, aggregating large numbers of individual IDS reports based on their impact The overall view reduces information overload by aggregating mult...

We consider strong Lloc(IR d) precompactness of the sequence of averaged quantities ∫ IRm hn(x, λ)ρ(λ)dλ, where ρ ∈ C0(IR), and hn ∈ L p loc(IR d× IRm), p > 1, are solutions to the transport equations with flux explicitly depending on space: divx(F (x, λ)hn(x, λ)) = d ∑ i=1 ∂xi∂ ki λ G i n(x, λ), x ∈ IR, λ ∈ IR, where F = (F1, ..., Fd), and Fi ∈ Lqloc(IR × IRm), i = 1, ..., d, 1/p + 1/q < 1, an...

Perceived self-efficacy (SE) for eating fruit and vegetables (FV) is a key variable mediating FV change in interventions. This study applies item response modeling (IRM) to a fruit, juice and vegetable self-efficacy questionnaire (FVSEQ) previously validated with classical test theory (CTT) procedures. The 24-item (five-point Likert scale) FVSEQ was administered to 1578 fourth graders from 26 H...

OBJECTIVE The aim of this study was to make a quantitative assessment of the sealing ability of Super-EBA, IRM, and Pro Root MTA root-end fillings subjected to 3 different finishing techniques. STUDY DESIGN Eighty-one ultrasonically prepared root-end cavities in human canines were separated randomly into 3 test groups of 27 roots each. The cavities were filled with Super-EBA, IRM, or Pro Root...

The use of mixtures of transgenic insecticidal seed and nontransgenic seed to provide an in-field refuge for susceptible insects in insect-resistance-management (IRM) plans has been considered for at least two decades. However, the U.S. Environmental Protection Agency has only recently authorized the practice. This commentary explores issues that regulators, industry, and other stakeholders sho...
