BeeNet: Reconstructing Flower Shapes from Electric Fields using Deep Learning Open
Arthropods, including pollinators, respond to environmental electrical fields. Here, we show that electric field information can be decoded to reconstruct environmental features. We develop an algorithm capable of inferring the shapes of p…

Electroreception in treehoppers: How extreme morphologies can increase electrical sensitivity Open
The link between form and function of an organism’s morphology is usually apparent or intuitive. However, some clades of organisms show remarkable diversity in their form, often exhibiting extreme morphologies, but with no obvious function…

A rotating three-dimensional body in coupled fluid motion near a wall: Stabilization and blow up Open
The three-dimensional interaction and evolution of a thin rotating body's motion within a surrounding fluid is presented here. The motion of each is shown to affect the other significantly through a dynamic fluid–body interaction. The cons…

Modelling floral and arthropod electrostatics using a two-domain AAA-least squares algorithm Open
Relationships between plants and insects vitally underpin the health of global ecosystems and food production. Through co-evolution, insects have acquired a variety of senses in response to the emergence of floral cues such as scent, colou…

Sensing electrical environments: mechanical object reconstruction via electrosensors Open
Increasing empirical evidence suggests that many terrestrial arthropods, such as bees, spiders, and caterpillars, sense electric fields in their environments. This relatively newly discovered sense may play a unique role within their broad…

Subjective Causes for Failure to Return to Sport After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis Open
Context: While current literature has explored the outcomes of athletes who return to sport (RTS) after anterior cruciate ligament (ACL) injuries, less is known about the outcomes of those who are unsuccessful in returning to sport. Object…

An analysis of time-varying dynamics in electrically sensitive arthropod hairs to understand real-world electrical sensing Open
With increasing evidence of electroreception in terrestrial arthropods, an understanding of receptor level processes is vital to appreciating the capabilities and limits of this sense. Here, we examine the spatio-temporal sensitivity of me…

On modelling fluid/body interactions, impacts and lift-offs Open
A description is given of recent progress in the understanding of mechanisms in fluid-body interactions where the motion of a body and the motion of the surrounding fluid affect each other substantially. The mathematical modelling of such …

The role of body shape and mass in skimming on water Open
Over many years, there has been great practical interest in how solid bodies interact with and skim on liquid layers. In the present investigation, the focus is on the important role of body mass and shape in such skimming motions. Conside…

Passive electrolocation in terrestrial arthropods: Theoretical modelling of location detection Open
The recent discovery that some terrestrial arthropods can detect, use, and learn from weak electrical fields adds a new dimension to our understanding of how organisms explore and interact with their environments. For bees and spiders, the…

Teaching Teledermatology: A Simulation Pilot for Health Professional Students Open
We developed a teledermatology simulation to give medical and physician assistant students practice with live videoconferencing and store-and-forward workflows. The simulation included (1) pre-session reading; (2) a brief teledermatology d…

Skimming impact of a thin heavy body on a shallow liquid layer Open
This study addresses the question of whether a thin, relatively heavy solid body with a smooth under-surface can skim on a shallow layer of liquid (for example water), i.e. impact on the layer and rebound from it. The body impacts obliquel…

The mechanics and interactions of electrically sensitive mechanoreceptive hair arrays of arthropods Open
Recent investigations highlight the possibility of electroreception within arthropods through charged mechanosensory hairs. This discovery raises questions about the influence of electrostatic interaction between hairs and surrounding elec…

When a small thin two-dimensional body enters a viscous wall layer Open
If a body enters a viscous-inviscid fluid layer near a wall, then significant effects can be felt from the presence of incident vorticity, viscous forces and nonlinear forces. The focus here is on the response in the outer edge of such a w…
