Neurexins have been proposed to function as major mediators of the coordinated pre- and postsynaptic apposition. However, key evidence for this role in vivo has been lacking, particularly due to gene redundancy. Here, we have obtained null mutations in the single Drosophila neurexin gene (dnrx). dnrx loss of function prevents the normal proliferation of synaptic boutons at glutamatergic neuromu...

In this study the rheological and physicochemical properties of four types of honeys, two poly floral (Mountain, Forest) and two mono floral (Sunflower, Ivy), were investigated. Rheological characteristics of honeys were evaluated at different temperatures (10, 15, 20, 25 and 30ºC). All the honeys exhibited Newtonian behavior for shear rate in the range of 1.045-41.8 s-1. The viscosity of sampl...

We propose a method for building an interpretable recommender system for personalizing online content and promotions. Historical data available for the system consists of customer features, provided content (promotions), and user responses. Unlike in a standard multi-class classification setting, misclassification costs depend on both recommended actions and customers. Our method transforms suc...

Welfare assessment methods have developed greatly over recent decades with regards to both behavioural and physiological indicators. However, whether welfare is being assessed on the basis of biological function, affective state or ‘naturalness’, the emphases have remained heavily on identifying those key indicators of poor welfare or welfare concerns that require more immediate action, often v...

This paper presents a novel impedance-based approach for out-of-step (OOS) protection of a synchronous generator. The most popular and commonly used approaches for detecting OOS conditions are based on the measurement of positive sequence impedance at relay location. However, FACTS devices change the measured impedance value and thus disrupt the performance of impedance-based relay function. In...

Given a query, aggregated search aims at aggregating information nuggets retrieved from differents sources. The aggregated result is a coherent answer that can be seen as an alternative to the traditional ranked list of documents. We focus in this paper on relational aggregated search where information nuggets are mainly classes, instances and attributes. We present a result aggregation approac...

We propose a communication activation robot and evaluate effectiveness of communication activation. As an example of application, we developed the system participating in a quizformed party game called NANDOKU quiz on a multi-modal conversation robot SCHEMA, and we conducted an experiment in a laboratory to evaluate its capability of activation in group communication. We evaluated interaction i...
