Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

open access: yesInsect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Aerodynamic Shape Design and Validation of an Advanced High-Lift Device for a Regional Aircraft with Morphing Droop Nose

open access: yesInternational Journal of Aerospace Engineering, 2019
In the present work, the aerodynamic shape design of an advanced high-lift system for a natural laminar flow (NLF) wing, based on the combination of a morphing droop nose and a single slot trailing edge flap, is presented.

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

open access: yesIntegrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

Morphing of ‘flying’ shapes for autonomous underwater and aerial vehicles

open access: yes, 2009
Autonomous vehicles are energy poor and should be designed to minimise the power required to propel them throughout their mission. The University of Southampton’s School of Engineering Sciences is actively involved in the development of improved designs ...

Design & modelling of a composite rudderless aeroelastic fin structure [PDF]

open access: yes, 2010
This thesis presents the study of a gapless and rudderless aeroelastic fin (GRAF) to enhance the directional stability and controllability of an aircraft. The GRAF concept was proposed and developed in the wake of previous research, targeted to improve

Morphing Wing Aircraft Using Piezoelectric Actuators

open access: yes, 2015
Using macro-fiber composites as aircraft control surfaces, rather than the hinged flaps of current aircraft, decreases energy and fuel consumption, and can increase wing versatility along with the aircraft's range and endurance.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

open access: yesAgricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Democratising Multi‐Projector Displays

open access: yesComputer Graphics Forum, EarlyView.
Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...
