Design of Gas Turbine Cooling System Based on Improved Jumping Spider Optimization Algorithm

open access: yesMachines, 2022
The gas turbine cooling system is a complex MIMO system with a strong coupling, nonlinear, time-varying and large disturbance amplitude. In order to automatically control the target flow, target temperature and pipeline pressure, in this paper, the ...

Regal Jumping Spider, Phidippus regius C. L. Koch (Arachnida: Salticidae)

open access: yesEDIS, 2003
Except for two pantropical species (Edwards 1979), the jumping spider most frequently encountered in Florida is Phidippus regius C.L. Koch. This species is aptly named in terms of its size, as it is the largest jumping spider in eastern North America ...

Jumping spider invades an orb web to prey on a resident male

open access: yesEcosphere, 2023
While surveying operational sex ratios of the giant golden orb weaver Nephila pilipes (Fabricius, 1793) in Singapore, we documented a stunning case of predatory behavior of a jumping spider Viciria pavesii Thorell, 1877. A female V.

AN ENHANCED JUMPING SPIDER OPTIMIZATION ALGORITHM [PDF]

open access: yesCarpathian Journal of Electrical Engineering, 2022
Jumping Spider Optimization (JSO) algorithm is a more recent meta-heuristic algorithm shown to outperform recent algorithms in the literature. This paper presents a JSO variant that modifies standard JSO in its global search and jumping on prey phases to

Predator mimicry: metalmark moths mimic their jumping spider predators. [PDF]

open access: yesPLoS ONE, 2006
Cases of mimicry provide many of the nature's most convincing examples of natural selection. Here we report evidence for a case of predator mimicry in which metalmark moths in the genus Brenthia mimic jumping spiders, one of their predators.

Phylogenetic, ecological and morphological characteristics reveal two new spider-associated genera in Clavicipitaceae [PDF]

open access: yesMycoKeys, 2022
Clavicipitaceous fungi are pathogenic to scale insects, white flies and other insect orders. However, a few species are spider-associated. Two new genera from China, Neoaraneomyces and Pseudometarhizium, are described based on phylogenetic, ecological ...

Rapid mid-jump production of high-performance silk by jumping spiders [PDF]

open access: yesCurrent Biology, 2021
Jumping spiders (Salticidae) do not rely on webs to capture their prey, but they do spin a silk dragline behind them as they move through their habitat. They also spin this dragline during jumps, continuously connecting them with the surface they leapt from.

Perception of biological motion by jumping spiders

open access: yesPLOS Biology, 2021
The body of most creatures is composed of interconnected joints. During motion, the spatial location of these joints changes, but they must maintain their distances to one another, effectively moving semirigidly. This pattern, termed “biological motion” in the literature, can be used as a visual cue, enabling many animals (including humans) to ...
