It takes just 300 ms to our brain to understand whether one person's facial mimic and body language are consistent with her inner feelings and mental states or with a verbal description of her feelings and mentations. And, when they are not, that person's verbal message has a short life in our brain. Indeed, our brain very quickly compares the inputs deriving from areas processing facial expressions, and face and body mimics (including the mirror neurons system) with the visceral feelings of ...

A mild decrease of oxygen supply to the brain can selectively impair the brain's arousal levels and behavioral responses, but not orienting of spatial attention and executive control functions.

These findings were presented at the "2014 Society for Neuroscience" Annual Congress, the largest and most influential Neuroscience ...

Emerging phenomena like UBER, Car2Go, Enjoy, etc. are examples of the increasing trend towards a sharing of mobility resources. What are the effects of this trend on urban traffic? In principle, a better utilization of mobility resources (vehicles, bikes, etc.) hints to a more sustainable urban traffic, but can we provide a quantification of these benefits at the city level? To address this and related questions, jointly with MIT Senseable City Lab, we have introduced a novel, network-based ...

Nowadays, data sharing through Cloud platforms is widespread among the Internet users, think for example to services such as Dropbox and Google Drive, and it is also facilitated by the availability of such sharing tools on mobile devices . However, in some scenarios, in particular when organizations are involved (e.g., companies or public bodies), this data sharing must be regulated by real digital contracts, called Data Sharing Agreements (DSA), which must be paired with data. The researchers ...

Conventional techniques of Terahertz spectroscopy (which use the range of electromagnetic radiation between infrared and microwave) reach a spatial resolution that, depending on the radiation used, cannot go beyond an intrinsic limit, the so-called diffraction limit, which is between 3 and 3000 microns. This limitation thus only allows the investigation of ensembles, in which the relevant physical parameters are estimated as the mean value of the size, orientation, shape, and density of ...

The perfect coherent absorption, observed for the first time 3 years ago in a silicon slab, has attracted a great interest in the scientific community because from a theoretical point of view it is the reverse of the laser: in fact it gives rise to a device that absorbs the light completely, contrary to the laser which generates it. In general the absorption of light by a material depends on its dielectric properties and increases in proportion to its thickness. However, when not one beam but ...

Il processo di integrazione europea passa anche attraverso la creazione di uno "Spazio europeo di giustizia". Viviane Reding, Vicepresidente della Commissione europea e Commissaria per la Giustizia, ha dichiarato: «Nel giro di pochi anni, la politica di giustizia è salita alla ribalta dell'attività dell'Unione europea, un po' come l'impulso dato al mercato unico negli anni '90. Abbiamo fatto molta strada, ma il cammino per sviluppare un vero spazio europeo di giustizia è ancora ...

Spin control of single electrons is of great interest for future applications in electronics and spintronics. However, to observe these phenomena at room temperature it is necessary to confine the electrons to conductive islands with reduced size, almost atomic. Although this type of confinement is feasible today, the technological difficulty is to control independently the different conductive islands separated by a few nanometers. A goal almost prohibitive. Recently a group of researchers from ...
