Adaptive evolution of butterfly wing shape: from morphology to behaviour

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2019
Butterflies display extreme variation in wing shape associated with tremendous ecological diversity. Disentangling the role of neutral versus adaptive processes in wing shape diversification remains a challenge for evolutionary biologists.

Influence of van der Waals forces on the adsorption structure of benzene on silicon studied using density functional theory [PDF]

open access: yes, 2008
Two different adsorption configurations of benzene on the Si(001)-(2 x 1) surface, the tight-bridge and butterfly structures, were studied using density functional theory.

The genome sequence of the Gold Spot moth, Plusia festucae (Linnaeus, 1758) [version 1; peer review: 2 approved]

open access: yesWellcome Open Research
We present a genome assembly from an individual male specimen of Plusia festucae (Gold Spot; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence has a total length of 422.50 megabases.

Acoustic characterization of Hofstadter butterfly with resonant scatterers

open access: yes, 2002
We are interested in the experimental characterization of the Hofstadter butterfly by means of acoustical waves. The transmission of an acoustic pulse through an array of 60 variable and resonant scatterers periodically distribued along a waveguide is ...

Butterfly Counting in Bipartite Networks [PDF]

open access: yesKnowledge Discovery and Data Mining, 2017
We consider the problem of counting motifs in bipartite affiliation networks, such as author-paper, user-product, and actor-movie relations. We focus on counting the number of occurrences of a "butterfly", a complete 2x2 biclique, the simplest cohesive ...

Phase Diagram for the Hofstadter butterfly and integer quantum Hall effect in three dimensions

open access: yes, 2001
We give a perspective on the Hofstadter butterfly (fractal energy spectrum in magnetic fields), which we have shown to arise specifically in three-dimensional(3D) systems in our previous work.

Landscape‐scale native woodland habitat restoration using natural tree regeneration provides a biodiversity boost for moths in the uplands

open access: yesEcological Solutions and Evidence
Afforestation of native woodland is a globally important political target with potential to meet biodiversity and climate change targets. Heavily deforested landscapes such as parts of the Scottish Highlands provide an opportunity to expand remaining ...

Block Copolymers: Emerging Building Blocks for Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
This review addresses how block copolymer (BCP) physics and rheology have led to the widespread use of BCPs in advanced additive manufacturing techniques, with particular emphasis on the untapped potential of these nanostructured materials toward achieving multi‐scale architected materials with unique, programmable material properties.

Universal Charge Diffusion and the Butterfly Effect in Holographic Theories. [PDF]

open access: yesPhysical Review Letters, 2016
We study charge diffusion in holographic scaling theories with a particle-hole symmetry. We show that these theories have a universal regime in which the diffusion constant is given by D_{c}=Cv_{B}^{2}/(2πT), where v_{B} is the velocity of the butterfly ...
