In his April 1994 interview with Ron Chepesiuk, Bill Ayers detailed his part in the 60s Radical Movement. Ayers described his motivations for joining the Students for a Democratic Society community, the Weather Underground, and...
New fossils help pinpoint when some birds started relying on a seed-based diet and reveal that disparate bill shapes evolved repeatedly throughout bird evolutionary history.
In 1818, a spectre haunted Maryland—Unitarianism. That year, Unitarians dedicated a new church for their young movement, the “First Independent Church of Baltimore.” American Unitarianism was still emerging from the liberal wing...
In this paper we deal with diffusive relaxation limits of nonlinear systems of Euler type modeling chemotactic movement of cells toward Keller-Segel type systems. The approximating systems are either hyperbolicparabolic or...

In this paper we study a fully parabolic version of the Keller-Segel system in the presence of a volume filling effect which prevents blow-up of the L norm. This effect is sometimes referred to as prevention of overcrowding. As...

This article shows how Poland’s ruling party, Law and Justice (PiS), is attempting to apply its general strategy of “elite replacement” in a modified way to civil society. Since independent civil society organizations...
A population-level model of bacterial chemotaxis is derived from a simple bacterial-level model of behavior. This model, to be contrasted with the Keller–Segel equations, exhibits behavior we refer to as the “volcano effect”...
Using methods from classical absolute stability theory, combined with recent results on input-to-state stability (ISS) of Lur’e systems, we derive necessary and sufficient conditions for a class of Lur’e systems to have the...
As it stands at the time of writing, Clause 145 of the Legal Aid, Sentencing and Punishment of Offenders Bill will make trespassing in a residential building a criminal offence. The Bill – as at 25 April 2012 – is at the “ping...

The 2019 novel coronavirus outbreak is unprecedented. Yet some look to ready-made models to addressit. This creates confusion about more adaptive responses that reflect an uncertain and ambiguous context.Those assessing...
This paper argues that EU security policy suffers from an intrinsic, gnawing weakness. This weakness, the hollowness in the flag, is the absence of the public.
In contrast to endless bureaucracies, meetings between...

Neurodegenerative diseases (NDs) including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, and Huntington’s disease are incurable and affect millions of people worldwide. The development of treatments...

Background One of the objectives of the Faculty of Medicine, Memorial University, is to train medical practitioners to serve the population of Newfoundland and Labrador with an emphasis on rural practice. Since the first...
We present a novel management methodology for restocking a declining population. The strategy uses integral control, a concept ubiquitous in control theory which has not been applied to population dynamics. Integral control is...
