A Sensors System for Indoor Localisation of a Moving Target Based on Infrared Pattern Recognition
(INTECH Open Access Publisher, 2007)A novel method for the indoor localisation of a target was presented in this chapter. This method is based on measuring the number of the digital infrared patterns received by the target in a specific time interval (success ... -
A severe red tide causes an anomalous decrease in biological sound
(2015)Although harmful algal blooms (HABs) are known to cause morbidity and mortality in marine organisms, their sublethal effects are poorly understood. The purpose of this study was to compare ambient noise levels during a ... -
Sex and hibernaculum temperature predict survivorship inwhite-nose syndrome affected little brownmyotis
(The Royal Society, 2015)White-nose syndrome (WNS), an emerging infectious disease caused by the novel fungus Pseudogymnoascus destructans,has devastated North American bat populations since its discovery in 2006. The little brown myotis,Myotis ... -
Sex differences in risk-taking and associative learning in rats
(2015)In many species, males tend to have lower parental investment than females and greater variance in their reproductive success. Males might therefore be expected to adopt more high-risk, high-return behaviours than females. ... -
Sex ratio effects on reproductive strategies in humans
(2015)Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex ... -
Sexual reproduction with variablemating systems can resist asexuality in a rock–paper–scissors dynamics
(The Royal Society, 2015)While sex can be advantageous for a lineage in the long term, we still lack an explanation for its maintenance with the twofold cost per generation. Here we model an infinite diploid population where two autosomal loci ... -
Sexual selection of male parental care in giant water bugs
(2016)Paternal care can be maintained under sexual selection, if it helps in attracting more mates. We tested the hypothesis in two giant water bug species,Appasus majorandAppasus japonicus, that male parental care is sexually ... -
Sexually selected lip colour indicates male group holding status in themating season in a multi-level primate society
(2015)Sexual selection typically produces ornaments in response to mate choice, and armaments in response to male–male competition. Unusually among mammals, many primates exhibit colour signals that may be related to one or both ... -
Shared Escovopsis parasites between leaf cutting and non leaf cutting ants in the higher attine fungus growing ant symbiosis
(2015)Fungus-gardening (attine) ants grow fungus for food in protected gardens, which contain beneficial, auxiliary microbes, but also microbes harmful to gardens. Among these potentially pathogenic microorganisms, the most ... -
Sharpening coarse-to-fine stereo vision by perceptual learning
(2016)Neurons in the early visual cortex are finely tuned to different low-level visual features, forming a multi-channel system analysing the visual image formed on the retina in a parallel manner. However, little is known about ... -
She more than he: gender bias supports the empathic nature of yawn contagion in Homo sapiens
(2016)Psychological clinical and neurobiological findings endorse that empathic abilities are more developed in women than in men. Because there is growing evidence that yawn contagion is an empathy-based phenomenon, we expect ... -
Short and long term consequences of developmental saline stress
(2016)Secondary salinization has been identified as a major stressor to amphibians. Exposure to elevated salinity necessitates physiological adjustments and biochemical changes that may be energetically demanding. As such, ... -
Shrinking fish: comparisons of prehistoric and contemporary salmonids indicate decreasing size at age across millennia
(The Royal Society, 2014)A comparison of Upper Palaeolithic and contemporary salmonid vertebrae from the Iberian Peninsula indicates that there has been a significant decrease in the mean body size for a given age among Atlantic salmon and brown ... -
Signalling with a cryptic trait
(2016)Sexual signals often compromise camouflage because of their conspicuousness. Pigmentation patterns, on the contrary, aid in camouflage. It was hypothesized that a particular type of pattern—barred plumage in birds, whereby ... -
Silver spoon effects on plumage quality in a passerine bird
(2015)A silver spoon effect means that individuals who develop under favourable circumstances enjoy a fitness or performance advantage later in life. While there is large empirical support for silver spoon effects acting on ... -
Simple graphmodels of information spread in finite populations
(The Royal Society, 2015)We consider several classes of simple graphs as potential models for information diffusion in a structured population. These include biases cycles, dual circular flows, partial bipartite graphs and what we call ‘single-link’ ... -
Simulated annealing approach to vascular structure with application to the coronary arteries
(2016)Department of Physical Sciences, The Open University, Milton Keynes MK7 6AA, UK 2 Department of Cardiovascular Sciences, University of Leicester, Leicester LE1 5WW, UK Do the complex processes of angiogenesis during organism ... -
Simulating droplet motion on virtual leaf surfaces
(The Royal Society, 2015)A curvilinear thin film model is used to simulate the motion of droplets on a virtual leaf surface, with a view to better understand the retention of agricultural sprays on plants. The governing model, adapted from Royet ... -
Simultaneous DNA-based diet analysis of breeding, non-breeding and chick Adélie penguins
(2016)As central place foragers, breeding penguins are restricted in foraging range by the need to return to the colony to feed chicks. Furthermore, breeding birds must balance energetic gain from self-feeding with the costs of ... -
