This work describes a novel solution to remote R. ferrugineus monitoring. Classical, plastic RPW traps containing aggregation pheromones for RPW are modified to include an optical sensor that senses adult pests falling in the trap. The counts of the pests are accumulated...

Valveless, tubular pumps are widespread in the animal kingdom, but the mechanism by which these pumps generate fluid flow are often in dispute. Where the pumping mechanism of many organs was once described as peristalsis, other mechanisms, such as dynamic suction...

This paper explores a possible underlying tenet of classical information-feed pathways (feedback and feedforward) as seen in metabolism and signaling in biological systems. We intend to determine whether information-feed pathways derive from spatial and temporal...

This work follows as a response to a problem posed in a previous work (Jeff-Eke, 2015b). Here we propose and explore a probable solution to the posed problem of how well a cellular system can tolerate random changes to the frequency of osmolytes infused into an...

This is a companion to A Gauge model for analysis of Biological systems. Here we reconcile the gauge model with a “real” system, which in this case is a unicellular system. We address effects of infusion of free osmolytes into an intracellular space of interest,...

In a number of recent studies we used computer modeling to investigate the evolution of muscle leverage (moment arms) and function in extant and extinct archosaur lineages (crocodilians, dinosaurs including birds and pterosaurs). These studies sought to quantify...
