Radio Frequency Interference Observations at IAR La Plata

The Wettzell RFI-Monitoring system was developed to monitor radio frequency interference at existing and potential VLBI sites. It is a transportable system which can be operated in a semiautomated manner. It was used at the Instituto Argentino de Radioastronomía in La Plata to investigate a future site for the Transportable Integrated Geodetic Observatory (TIGO). With the help of an automated pedestal for the RFI-monitoring antenna a 24h/7d survey was conducted during September and October 2012. This data set is one of the most dense RFI-monitoring samples known within the IVS. The results of this survey showed, that most of the present RFI signals occure sporadically and take away less than 5% of the observation time. Hence IAR is a suitable site for TIGO.Fil: Haze, Hayo.

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

What can we make of theories of embodiment and the role of the human mirror neuron system?

In recent years, work surrounding theories of embodiment and the role of the putative mirror neuron system (MNS) in humans has gained considerable attention. If humans have developed a net-work of neurons that fire in response to other beings’ actions, as has been shown in macaques, this system could have vast implications for all kinds of cognitive processes unique to humans, such as language, learning, empathy and communication in general. The goal of tapping into and understanding such a system is a fascinating yet challenging one. One form of embodiment - embodied linguistics - suggests that the way we process linguistic information is linked to our physical experience of the concept conveyed by each word. The interaction between these cognitive systems (i.e., language and motor processing) may occur thanks to the firing of neurons making up the MNS. The possible interdependence between different cognitive systems has implications for healthy as well as pathological profiles, and in fact, work in recent years has also explored the role of ‘embodiment’ and/or the MNS in clinical populations such as stroke, Parkinson’s Disease, Alzheimer’s Disease, and Autism, among others. Research on embodiment and/or the MNS has been approached with a number of different methodologies, but the results obtained with these different methodologies have not been entirely consistent, generating doubts regarding the theories. The question has been raised as to what this line of inquiry can gain from the types of evidence contributed by functional neuroimaging methods carried out with healthy volunteers versus behavioral or lesion-symptom mapping methods employed with neurologically-compromised individuals. Of particular interest are the clinical applications of this line of research. If indeed a system exists which reflects a tight link between, for example, the human language and motor systems, then the obvious challenge is to tap into this system to create useful therapies that can provide rehabilitation where damage has occurred. This Research Topic brought together work conducted with healthy and patient populations using several behavioral and imaging techniques, as well as insightful commentaries and opinion pieces. We believe the combined work of the participating authors is an important contribution to this intriguing line of research and an excellent point of reference for future work

CETA: open, affordable and portable mixed-reality environment for low-cost tablets

Comunicació presentada a: MobileHCI ’17, celebrat a Viena, Àustria, del 4 al 7 de setembre de 2017.Mixed-reality environments allow to combine tangible interaction with digital feedback, empowering interaction designers to take benefits from both real and virtual worlds. This interaction paradigm is also being applied in classrooms for learning purposes. However, most of the times the devices supporting mixed-reality interaction are neither portable nor affordable, which could be a limitation in the learning context. In this paper we propose CETA, a mixed-reality environment using low-cost Android tablets which tackles portability and costs issues. In addition, CETA is open-source, reproducible and extensible.This project is funded by the National Agency for Research and Innovation of Uruguay through its Digital Inclusion Grant (Fondo Sectorial "Inclusión Digital: Educación con Nuevos Horizontes" - 2015:FSED_2_2015_1_120888)
