Current tools for interactive knowledge capture have little or no learning aptitude. They are mostly oblivious to the process or strategy that the user may be following in entering new knowledge, unaware of their progress during a session, and ignorant of typical skills expected from a good student. We present an approach to make acquisition interfaces more proactive by extending them with: 1) ...

We consider the following sample selection problem. We observe in an online fashion a sequence of samples, each endowed by a quality. Our goal is to either select or reject each sample, so as to maximize the aggregate quality of the subsample selected so far. There is a natural trade-off here between the rate of selection and the aggregate quality of the subsample. We show that for a number of ...

In translation, choosing appropriate equivalent is essential to convey the right message from source-text to target-text, and one of the issues that may have a determinative role in appropriate equivalent choice is the semantic prosody (SP) behavior of words and the relation existing between the SP of a word and semantic senses (i.e. negativity, positivity or neutrality) of its collocations in ...

Methods We compared functional respiratory testing in 72 asthmatic children (mean age 11.4±2.6 years) and in 70 healthy subjects (mean age 12.5±2.5 years). Each group was divided in 2 subgroups using a physical activity level cut-off (< 2 or > 3 hours spent for week), that way generating 4 study groups: asthmatic trained children, non asthmatic trained children, trained controls, non trained co...

A 12-year-old boy suffered injuries to his left forearm and elbow in a fall from a bicycle. Radiographs of the left elbow and forearm revealed a type IV Monteggia lesion (Fig. 1). During close manipulation, the greenstick radial fracture became partially displaced. However, length of the ulna and its alignment together with reduction of the radial head were satisfactorily obtained. Thereafter, ...
