Mouse and rat ultrasonic vocalizations in neuroscience and neuropharmacology: State of the art and future applications
Mice and rats emit ultrasonic vocalizations (USVs), which may express their arousal and emotional states, to communicate with each other. There is continued scientific effort to better understand the functions of USVs as a central element of the rodent behavioral repertoire. However, studying USVs is not only important because of their ethological relevance, but also because they are widely applied as a behavioral readout in various fields of biomedical research. In mice and rats, a large number of experimental models of brain disorders exist and studying the emission of USVs in these models can provide valuable information about the health status of the animals and the effectiveness of possible interventions, both environmental and pharmacological. This review (i) provides an updated overview of the contexts in which ultrasonic calling behaviour of mice and rats has particularly high translational value, and (ii) gives some examples of novel approaches and tools used for the analysis of USVs in mice and rats, combining qualitative and quantitative methods. The relevance of age and sex differences as well as the importance of longitudinal evaluations of calling and non-calling behaviour is also discussed. Finally, the importance of assessing the communicative impact of USVs in the receiver, that is, through playback studies, is highlighted
Análise da recente alta internacional dos preços das commodities alimentares: previsão e mudança estrutural.
Este artigo tem como objetivo analisar a alta observada entre 2007 e 2011 nos preços das commodities de alimentação em âmbito internacional, tendo como motivação os efeitos prejudiciais que a elevação dos preços desse tipo de produto causa à segurança alimentar mundial. Por meio do método de Box e Jenkins (1976), busca-se estudar o comportamento dos preços nos meses que completam o ano de 2011 e, utilizando-se a análise de quebra estrutural, procura-se comprovar a quebra estrutural no período de maior alta. O estudo permite verificar que existe uma tendência de alta nos preços dos alimentos e de mudança estrutural na base de formação deles, evidenciando a necessidade de políticas públicas, em âmbito internacional, que assistam ao problema
Mobile Edge Cloud Network Design Optimization
Major interest is currently given to the integration of clusters of virtualization servers, also referred to as 'cloudlets' or 'edge clouds', into the access network to allow higher performance and reliability in the access to mobile edge computing services. We tackle the edge cloud network design problem for mobile access networks. The model is such that the virtual machines (VMs) are associated with mobile users and are allocated to cloudlets. Designing an edge cloud network implies first determining where to install cloudlet facilities among the available sites, then assigning sets of access points, such as base stations to cloudlets, while supporting VM orchestration and considering partial user mobility information, as well as the satisfaction of service-level agreements. We present link-path formulations supported by heuristics to compute solutions in reasonable time. We qualify the advantage in considering mobility for both users and VMs as up to 20% less users not satisfied in their SLA with a little increase of opened facilities. We compare two VM mobility modes, bulk and live migration, as a function of mobile cloud service requirements, determining that a high preference should be given to live migration, while bulk migrations seem to be a feasible alternative on delay-stringent tiny-disk services, such as augmented reality support, and only with further relaxation on network constraints
