objective: children with attention deficit hyperactivity disorder (adhd) do not process most information due to inattention and loss of the opportunity to save and retrieve information. therefore, these children experience memory impairment. although visual memory has been previously studied in children with adhd, iconic memory in these children has been less evaluated. we aimed to study the po...

Courtship in Drosophila is used already to screen genes linked to memory-deficiency and neurodegeneration in humans. However the research community does not understand the mechanism which gives rise to courtship patterns. When a male fly encounters a female fly, he starts to follow her, licks her genitalia, sings a courtship song and eventually bends his abdomen to reach her genitalia [1]. Male...

A hierarchical clustering algorithm based on Gaussian mixture model is presented. The key difference to regular hierarchical mixture models is the ability to store objects in both terminal and nonterminal nodes. Upper levels of the hierarchy contain sparsely distributed objects, while lower levels contain densely represented ones. As it was shown by experiments, this ability helps in noise dete...

We present the LexGram system as a lean and lexicalist grammar formalism, which ooers a small but powerful set of linguistic tools. Such a lean formalism is easier and faster to implement, since a smaller number of operations have to be modelled. In addition, we argue that grammar writing itself is alleviated. LexGram supports a very concise encoding of grammars as an inheritance hierarchy of s...
