Perimeter Protection of the Areas of Interest

This article analyses the history and current state in the area of outdoor protection. In the first part of the article, the sensory systems, which have been used for many years are described. Attention is paid to the sensors using conventional principles of the detection of the objects. New modern sensory systems together with their principles used for the protection of the outdoor environment are also described. Other problem is that older sensory systems of spatial protection were focused on the security of properties and buildings without expecting any change position in the time. The article analyzes also new possibilities of protecting of the outdoor perimeter even in the situations when the borders of the areas of interest are only temporary or mobile. And as UAV systems have been used massively and often involve modern multisensory systems, the last part of the article describes current sensors, which have been currently used to detect the UAV systems and to to protect the area of interest.

Using Multisensory Technologies to Stimulate People: a Reflexive Paper on Scenagrams

This paper aims at discussing the interest to use multisensory technologies for humans cognition training. First it introduces multisensory interactions making a focus on advancement in two fields: Human-Computer Interaction and mulsemedia. Second, it presents two different multisensory systems resulting from Robadom and StimSense projects that could be adapted for the community. Then, this paper defines the concept of scenagram and gives its application scopes, boundaries and use cases, offering a first classification of this new concept.

Shorebird’s Longer Migratory Distances are Associated with Larger ADCYAP1 Microsatellites and Greater Morphological Complexity of Hippocampal Astrocytes

Background For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. Methods We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Results Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. Conclusion We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.

Sensation of the tiniest kind: the antennal sensilla of the smallest free-living insect Scydosella musawasensis (Coleoptera: Ptiliidae)

Miniaturization is a major evolutionary trend prominent in insects, which has resulted in the existence of insects comparable in size to some unicellular protists. The adaptation of the complex antennal multisensory systems to extreme miniaturization is a fascinating problem, which remains almost unexplored. We studied the antennal sensilla of Scydosella musawasensis Hall, 1999 (Coleoptera: Ptiliidae), the smallest free-living insect, using scanning electron microscopy. The antenna of S. musawasensis bears 131 sensilla; no intraspecific variation in the number or position of the sensilla has been revealed. Nine different morphological types of sensilla are described according to their external morphological features and distribution: four types of sensilla trichodea, one type of sensilla chaetica, two types of sensilla styloconica, and two types of sensilla basiconica. Morphometric analysis of the sensilla of S. musawasensis, based on measurements of the lengths and diameters of sensilla and their location and number, showed the absence of significant differences between females and males. Comparative allometric analysis of S. musawasensis and larger Coleoptera showed that the number of sensilla and the size of sensilla chaetica decrease with decreasing body size. However, the number of the types of sensilla and the length and diameter of the multiporous sensilla basiconica revealed no correlation with the body size. Comparison of the acquired data with the results of our earlier study of the antennal sensilla of some of the smallest parasitic wasps is used to put forward hypotheses on the common principles of miniaturization of the antennal sensory systems of insects.

Multimodal Sensorimotor System in Unicellular Zoospores of a Fungus

Complex sensory suites often underlie critical behaviors, including avoiding predators or locating prey, mates, and shelter. Multisensory systems that control motor behavior even appear in unicellular eukaryotes, such as Chlamydomonas, which are important laboratory models for sensory biology. However, we know of no unicellular opisthokont models that control motor behavior using a multimodal sensory suite. Therefore, existing single-celled models for multimodal sensorimotor integration are very distantly related to animals. Here, we describe a multisensory system that controls the motor function of unicellular, fungal zoospores. We find zoospores of Allomyces arbusculus exhibit both phototaxis and chemotaxis. While swimming, they move towards light and settle on cellulose membranes exuding combinations of amino acids. Furthermore, we report that closely related Allomyces species do not share this multisensory system. Instead, each possesses only one of the two modalities present in A. arbusculus. This diversity of sensory suites within Allomyces provides a rare example of a comparative framework that can be used to examine the evolution of sensory suites. The tractability of Allomyces and related fungi as laboratory organisms will allow detailed mechanistic investigations into how sensory systems may have functioned in early opisthokonts before multicellularity allowed for the evolution of specialized cell types.Summary StatementZoospores’ ability to detect light or chemical gradients varies within Allomyces. Here, we report a multimodal sensory system controlling behavior in a fungus, and previously unknown variation in zoospore sensory suites.
