Variation in multicomponent recognition cues alters egg rejection decisions: A test of the optimal acceptance threshold hypothesis
(The Royal Society, 2019-04)
The optimal acceptance threshold hypothesis provides a general predictive framework for testing behavioural responses to discrimination challenges. Decision-makers should respond to a stimulus when the perceived difference ...
Nestmate recognition in a Neotropical swarm-founding wasp: no effect of seasonality on tolerance of alien conspecifics
(TAYLOR & FRANCIS LTD, 2008)
Previous study revealed that the swarm-founding wasp Polybia paulista is accurately able to distinguish nestmates from non-nestmates in the summer. However, the risk of accepting alien intruders is considered to be low in ...
Brown-and-yellow marshbirds reduce their acceptance threshold of mimetic brood parasite eggs in the presence of non-mimetic eggs
(Springer Tokyo, 2016-01)
The recognition and subsequent rejection of brood parasite eggs is one of the most commonly observed defensive behaviors of the host. The brown-and-yellow marshbird (Pseudoleistes virescens) is a common host of the shiny ...
Clustering binary data by application of combinatorial optimization heuristics
(2019-08-09)
We study clustering methods for binary data, first defining aggregation criteria that measure the compactness of clusters. Five new and original methods are introduced, using neighborhoods and population behavior combinatorial ...
Meta-heuristic approaches for a soft drink industry problem
(2008-11-24)
The present paper evaluates meta-heuristic approaches to solve a soft drink industry problem. This problem is motivated by a real situation found in soft drink companies, where the lot sizing and scheduling of raw materials ...

Acceptance Threshold Hypothesis is Supported by Chemical Similarity of Cuticular Hydrocarbons in a Stingless Bee, Melipona asilvai
(SPRINGERDORDRECHT, 2012)
The ability to discriminate nestmates from non-nestmates in insect societies is essential to protect colonies from conspecific invaders. The acceptance threshold hypothesis predicts that organisms whose recognition systems ...
The Efficiency Path: An Estimation of Cost-Effectiveness Thresholds for 185 Countries Based on Per Capita Health Expenditures and Life Expectancy
(Wiley Blackwell Publishing, Inc, 2015-11)
Objectives: Cost-effectiveness (CE) is increasingly used for resource allocationworldwide. One key hurdle for its widespread use is the lack of a widely acceptedmethodology to derive thresholds at the healthcare system ...
Enhanced Sparse Bayesian Learning via Statistical Thresholding for Signals in Structured Noise
(Institute of Electrical and Electronics Engineers, 2013-11)
In this paper we address the problem of sparse signal reconstruction. We propose a new algorithm that determines the signal support applying statistical thresholding to accept the active components of the model. This ...
