Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

open access: yesInsect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

MGA trajectory planning with an ACO-inspired algorithm [PDF]

open access: yes, 2009
Given a set of celestial bodies, the problem of finding an optimal sequence of gravity assist manoeuvres, deep space manoeuvres (DSM) and transfer arcs connecting two or more bodies in the set is combinatorial in nature.

Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

open access: yesIntegrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Ant-Colony Based Near-ML Space-Time Multiuser Detection for the STBC Assisted DS-CDMA Uplink

open access: yes, 2010
In this contribution, a novel Ant Colony Optimization (ACO) based Space-Time (ST) Multiuser Detection (MUD) algorithm was proposed in order to improve the Bit Error Ratio (BER) versus Signal-to-Noise Ratio (SNR) performance achieved by the Space-Time ...

Examining the Psychometric Properties of the Ultra‐Short Version of the Oral Health Impact Profile in Australia

open access: yesCommunity Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives The Oral Health Impact Profile (OHIP) is the most widely used instrument to measure the subjective impact of oral conditions. This study reports the shortening and psychometric evaluation of an ultra‐short version (OHIP‐7A) from the OHIP‐14 in a large national Australian population.

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations

open access: yesComputer Graphics Forum, EarlyView.
Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.
