A TSP Solving Model Based on Immune Ant Colony Hybrid Algorithm

open access: yes工程科学与技术, 2010
:In order to solve the problems caused by the traditional ant colony algorithm, such as searching slowly, cling to prematurity, standstill, and the inefficient and useless redundant iteration caused by feedback underutilized in traditional immune ...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Beta diversity of Arctiinae moths (Lepidoptera: Erebidae) along a recovering tropical forest gradient

open access: yesJournal of Animal Ecology, EarlyView.
Using novel approaches of Hill‐number based and coverage‐standardized dissimilarity metrics and community‐weighted traits, we show that tiger moth communities exhibit various traits prone to land‐use intensity and undergo a complex and non‐linear response to tropical rainforest recovery, corroborating recent findings on biotic differentiation (Keck et ...

The Doctrine of State Necessity

open access: yesThe Modern Law Review, EarlyView.
This article examines the doctrine of state necessity as a distinct but relatively underexplored doctrine of constitutional law. Drawing on case law from a range of jurisdictions, it considers instances in which courts have accepted otherwise unconstitutional measures as lawful in order to preserve the operation of state institutions or protect ...

‘The Tragedy of a Small Nation’: Alexander Devine and British Perspectives on the Montenegrin Question, 1918–24

open access: yesHistory, EarlyView.
Abstract This article examines the pro‐Montenegrin political campaigns of Alexander Devine, a schoolmaster and journalist who became Montenegro's leading British advocate following its incorporation into the Kingdom of Serbs, Croats and Slovenes after the First World War.

Ant-colony-based multiuser detection for multifunctional-antenna-array-assisted MC DS-CDMA systems

open access: yes, 2008
A novel Ant Colony Optimization (ACO) based Multi-User Detector (MUD) is designed for the synchronous Multi-Functional Antenna Array (MFAA) assisted Multi-Carrier Direct-Sequence Code-Division Multiple-Access (MC DS-CDMA) uplink (UL), which supports both

Effects of bleach on carcass postmortem microbiomes and necrophagous beetle carcass attendance and their internal microbiomes

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic entomology, and potentially microbiology in the future, can be used during death investigations to corroborate an estimated time since death. Instances where products are introduced to a cadaver, either in attempt to conceal or by accident, can affect decomposition and succession of associated decomposer taxa (i.e., insects and ...

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‐

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.
