Lacunae rostralis: A new structure on the rostrum of sailfish Istiophorus platypterus [PDF]
Journal of Fish Biology, 2022 AbstractRecent comparative studies of billfishes (Istiophoridae and Xiphiidae) have provided evidence of differences in the form and function of the rostra (bill) among species. Here, we report the discovery of a new structure, lacuna rostralis, on the rostra of sailfish Istiophorus platypterus, which is absent on the rostra of swordfish Xiphias ...

Engineering Science and Technology, an International Journal, 2022 The Sailfish Optimizer (SFO) is a metaheuristic algorithm inspired by a group of hunting sailfish that alternates their attacks on group of prey. The SFO algorithm takes advantage of using a simple method for providing the dynamic balance between ...

Consequences of ocean scale hypoxia constrained habitat for tropical pelagic fishes [PDF]
, 2007 Large areas of cold hypoxic water occur as distinct strata in the eastern tropical Pacific and Atlantic oceans as a result of high productivity initiated by intense nutrient upwelling.

International Aquatic Research, 2016 The reliability of estimations of catches of pelagic longline fisheries is especially worrying in the case of non-target species such as the sailfish (Istiophorus platypterus) and spearfish (Tetrapturus pfluegeri), because they are often recorded ...

Biology Open, 2016 Billfishes are considered to be among the fastest swimmers in the oceans. Previous studies have estimated maximum speed of sailfish and black marlin at around 35 m s−1 but theoretical work on cavitation predicts that such extreme speed is unlikely.

K-means Hybrid Iterative Clustering Based on Memory Transfer Sailfish Optimization
Shanghai Jiaotong Daxue xuebao, 2022 Aimed at the problem that the existing K-means clustering (KMC) algorithm is greatly affected by initialization, and the randomly generated clustering center can easily make the clustering result fall into local optimum and stop iterating, resulting in ...

The Evolution of Lateralization in Group Hunting Sailfish [PDF]
Current Biology, 2017 Lateralization is widespread throughout the animal kingdom [1-7] and can increase task efficiency via shortening reaction times and saving on neural tissue [8-16]. However, lateralization might be costly because it increases predictability [17-21].

Sailfish: Vetting Smart Contract State-Inconsistency Bugs in Seconds
SSRN Electronic Journal, 2022 This paper presents SAILFISH, a scalable system for automatically finding state-inconsistency bugs in smart contracts. To make the analysis tractable, we introduce a hybrid approach that includes (i) a light-weight exploration phase that dramatically reduces the number of instructions to analyze, and (ii) a precise refinement phase based on symbolic ...

Environmental and spatial effects on the size distribution of sailfish in the Atlantic ocean
Ciencias Marinas, 2010 Generalized regression analysis and spatial prediction (GRASP) was applied to size data for sailfish (Istiophorus platypterus) to better describe its preferential habitats in relation to juveniles and adults, based on environmental and spatial factors ...
