Impulsive functional differential equations with variable times
, 2005 In this paper we investigate the existence of solutions to some classes of impulsive functional and neutral differential equations with variable times and infinite delay, using the nonlinear alternative of Leray-Schauder type.

Journal of Research in Science Teaching, EarlyView.ABSTRACT Queer undergraduates describe a climate in STEM fields and classrooms that is both hostile to and silent on queer identities, leading to experiences of social exclusion, devaluation as a scientist, and discrimination. In the few studies that have specifically focused on trans and non‐binary undergraduates (i.e., students with queer genders ...

Impulsive fractional functional differential equations with a weakly continuous nonlinearity
Electronic Journal of Differential Equations, 2017 A general theorem on the local and global existence of solutions is established for an impulsive fractional delay differential equation with Caputo fractional substantial derivative in a separable Hilbert space under the assumption that the ...

Assessment of sampling variation applets during development
Teaching Statistics, EarlyView.Abstract Concepts relating to sampling variation are known to be difficult for learners in introductory classes. There is some evidence that web‐based visualization tools, or “applets,” may aid the learning of these challenging ideas. Four freely available applets developed at the authors' institution were extensively tested through sessions involving ...

Veterinary Record, EarlyView.Abstract Background Gastrointestinal nematode infections are ubiquitous in grazing livestock worldwide impacting animal health and production. Faecal egg count (FEC) is an accessible diagnostic test that can guide the need for treatment. However, interpretation of FECs can be challenging.

Acta Psychiatrica Scandinavica, EarlyView.ABSTRACT Introduction Major depressive disorder (MDD) and bipolar disorder (BD) are often associated with persistent cognitive deficits that impair psychosocial functioning. While pro‐cognitive interventions show promise, trial findings are inconsistent, potentially due to baseline factors influencing treatment response.

Comparison results for functional differential equations with impulses
Mathematica Slovaca, 2013 Abstract Comparison principles play an important role in the qualitative and quantitative study of differential equations. In this paper, we investigate a first order functional differential equations with impulses and establish new comparison results.

Addiction, EarlyView.Abstract Background and aims Appetitive responses, such as approach biases, are thought to play a crucial role in smoking. This study aimed to compare responses toward smoking‐related stimuli with responses in control conditions (e.g. non‐approach or neutral stimuli) using a multi‐method approach. By examining associations between response measures and
