The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

open access: yesInsect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Multi-criteria Scheduling in Parallel Environment with Learning Effect

open access: yesFoundations of Computing and Decision Sciences
This paper is devoted to the study of a multi-criteria scheduling problem on unrelated processors with machines’ learning effect, with the goal of minimizing makespan, machine cost and maximal flow-time simultaneously, which is an NP-hard problem.

Hybrid Bio-Optimized Algorithms for Hyperparameter Tuning in Machine Learning Models: A Software Defect Prediction Case Study

open access: yesMathematics
Addressing real-time optimization problems becomes increasingly challenging as their complexity continues to escalate over time. So bio-optimization algorithms (BoAs) come into the picture to solve such problems due to their global search capability ...

Long-range epidemic spreading with immunization

open access: yes, 2008
We study the phase transition between survival and extinction in an epidemic process with long-range interactions and immunization. This model can be viewed as the well-known general epidemic process (GEP) in which nearest-neighbor interactions are ...

Economic Valuation of Renewable Transport Fuels: Evidence From Solar Fuel Willingness to Pay in Quebec, Canada

open access: yesThe American Journal of Economics and Sociology, EarlyView.
ABSTRACT The transport sector is one of the largest contributors to global greenhouse gas emissions, making it a key priority for climate mitigation policies. In this context, renewable fuels represent a promising complementary pathway to transport electrification, particularly due to their compatibility with existing internal combustion engine ...

Fluctuation Dissipation Relation for a Langevin Model with Multiplicative Noise

open access: yes, 2001
A random multiplicative process with additive noise is described by a Langevin equation. We show that the fluctuation-dissipation relation is satisfied in the Langevin model, if the noise strength is not so strong.Comment: 11 pages, 6 figures, other ...
