ESTUDO PRELIMINAR DE PARADIGMA DE ESTRESSE PREDATÓRIO PARA INDUÇÃO DE ANSIEDADE EM CAMUNDONGOS SWISS
Multi-Science Journal, 2018 In this study we modified the predatory stress paradigms to determine if a simple and new predatory stress paradigm could produce anxiety-like behaviour in female Swiss mice, exposed to male Wistar rat.

Can We Automate the Analysis of Online Child Sexual Exploitation Discourse? [PDF]
arXiv, 2022 Social media's growing popularity raises concerns around children's online safety. Interactions between minors and adults with predatory intentions is a particularly grave concern. Research into online sexual grooming has often relied on domain experts to manually annotate conversations, limiting both scale and scope.

Awareness of Predatory Journals in Library and Information Science Faculties in India [PDF]
arXiv, 2022 Predatory journals that pretended to resemble refereed journals but are used for money-making purposes. Predatory publishers produce less quality scientific and research papers; it is a severe academic threat in scientific publications. Researchers are ensuring the quality of the journal and peer-reviewing process before submitting the manuscript. This

Comment on "Open is not forever: a study of vanished open access journals" [PDF]
J.Assoc.Info.Sci.Tech. 72 (2021) 1113-1114, 2020 We comment on a recent article by Laakso et al. (arXiv:2008.11933 [cs.DL]), in which the disappearance of 176 open access journals from the Internet is noted. We argue that one reason these journals may have vanished is that they were predatory journals. The de-listing of predators from the Directory of Open Access Journals in 2014 and the abundance of

Tropical House Gecko (Hemidactylus mabouia) predation on brown spiders (Loxosceles intermedia)
Journal of Venomous Animals and Toxins including Tropical Diseases, 2004 Brown spiders (Loxosceles spp.) are venomous arachnids, successfully adapted to urban habitats in Brazil. Loxoscelism became a serious public health problem in Paraná State, especially at the capital Curitiba, where the most abundant species is ...

The predatory behavior of the Neotropical social wasp Polybia rejecta [PDF]
Behavioural Processes, 2017 We experimentally studied the predatory behavior of Polybia rejecta (Vespidae, Polistinae, Epiponini) towards 2-88 mm-long insects attracted to a UV light trap. Foragers, which began to hunt at 6:30, selected 4-14 mm-long prey insects. Prey detection by sight by hovering wasps was confirmed using decoys.

Algorithms, Incentives, and Democracy [PDF]
arXiv, 2023 Classification algorithms are increasingly used in areas such as housing, credit, and law enforcement in order to make decisions affecting peoples' lives. These algorithms can change individual behavior deliberately (a fraud prediction algorithm deterring fraud) or inadvertently (content sorting algorithms spreading misinformation), and they are ...

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

Chemotactic predator-prey dynamics [PDF]
, 2010 A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady hunting is unstable.

Optimising low-Reynolds-number predation via optimal control and reinforcement learning [PDF]
, 2022 We seek the best stroke sequences of a finite-size swimming predator chasing a non-motile point or finite--size prey at low Reynolds number. We use optimal control to seek the globally-optimal solutions for the former and RL for general situations. The predator is represented by a squirmer model that can translate forward and laterally, rotate and ...
