Large Spatial Scale of the Phenotype-Environment Color Matching in Two Cryptic Species of African Desert Jerboas (Dipodidae: Jaculus)

2014

We tested the camouflage hypothesis, or the linkage between animal (Saharan rodent) and habitat coloration, on the largest geographical scale yet conducted. We aimed to determine whether phenotypic variation is explained by micro-habitat variation and/or genetic polymorphism to determine 1) the strength of linkage between fur color and local substrate color, and 2) the divergence in fur coloration between two genetic clades, representing cryptic species, throughout the complete range of the African desert jerboas (Jaculus jaculus). We used a combination of museum and field-collected specimens, remote sensing tools, satellite and digital photography and molecular genetic and phylogenetic met…

Portion size selection in children: Effect of sensory imagery for snacks varying in energy density

2020

Food sensory imagery - creating a vivid mental image of the sensory experience of eating - can lead to the selection of smaller portions because it serves as a reminder that eating enjoyment does not necessarily increase with portion size. The evidence is mostly limited to adults and to energy-dense foods for which it is particularly difficult to predict the satiating effects of consumption quantity. The objective was to study how food sensory imagery influences portion size selection of foods varying in energy density (brownie and applesauce) by 7- to 11-year-old children. During after-school time, 171 children were randomized into two conditions. Children in the food sensory imagery condi…

Spinal plasticity with motor imagery practice.

2019

KEY POINTS: While a consensus has now been reached on the effect of motor imagery (MI) – the mental simulation of an action – on motor cortical areas, less is known about its impact on spinal structures. The current study, using H‐reflex conditioning paradigms, examined the effect of a 20 min MI practice on several spinal mechanisms of the plantar flexor muscles. We observed modulations of spinal presynaptic circuitry while imagining, which was even more pronounced following an acute session of MI practice. We suggested that the small cortical output generated during MI may reach specific spinal circuits and that repeating MI may increase the sensitivity of the spinal cord to its effects. T…

Complete locked-in and locked-in patients: Command following assessment and communication with vibro-tactile P300 and motor imagery brain-computer in…

2017

Many patients with locked-in syndrome (LIS) or complete locked-in syndrome (CLIS) also need brain-computer interface (BCI) platforms that do not rely on visual stimuli and are easy to use. We investigate command following and communication functions of mindBEAGLE with 9 LIS, 3 CLIS patients and three healthy controls. This tests were done with vibro-tactile stimulation with 2 or 3 stimulators (VT2 and VT3 mode) and with motor imagery (MI) paradigms. In VT2 the stimulators are fixed on the left and right wrist and the participant has the task to count the stimuli on the target hand in order to elicit a P300 response. In VT3 mode an additional stimulator is placed as a distractor on the shoul…

Athletic abs or big bellies:The impact of imagery, arousal levels, and health consciousness on consumers’ attitudes towards plant-based protein produ…

2021

Abstract Research suggests that health-related imagery influences consumers’ product attitudes, and that both appetitive, positively framed and aversive, negatively framed imagery can be used to boost health-related responses. Arousal has been suggested as a mechanism driving such responses, but few studies in food-related consumer research have examined the link between arousal and consumers’ product attitudes. The present cross-national study, involving almost 1000 consumers (N = 959) from Denmark, Germany, Spain, and the UK, experimentally investigated whether prior exposure to healthy (vs. unhealthy) imagery influences consumers’ attitudes towards a plant-based protein product. Furtherm…

Architectures en vertige et « topographie » du personnage chez Julien Green

2018

L’architettura è senza dubbio uno degli assi fondamentali attorno al quale si dispiega l’immaginario di Julien Green, la cui opera è ricca di dimore, castelli, camere, biblioteche, spazi urbani. Attraverso l’analisi di tre romanzi (Mont-Cinère, Adrienne Mesurat, Minuit), l’articolo si propone di mostrare, per mezzo del riferimento metodologico ai Séminaires e agli Écrits di Lacan, che gli spazi architettonici rappresentati assumono nello scrittore una dimensione trascendente che realizza lo slittamento dagli spazi reali alla topologia soggettiva dei personaggi. Architecture is undeniably one of the fundamental axes around which the imagery of Julien Green unfolds, whose work is full of hous…

Remote sensing image segmentation by active queries

2012

Active learning deals with developing methods that select examples that may express data characteristics in a compact way. For remote sensing image segmentation, the selected samples are the most informative pixels in the image so that classifiers trained with reduced active datasets become faster and more robust. Strategies for intelligent sampling have been proposed with model-based heuristics aiming at the search of the most informative pixels to optimize model's performance. Unlike standard methods that concentrate on model optimization, here we propose a method inspired in the cluster assumption that holds in most of the remote sensing data. Starting from a complete hierarchical descri…
