In 100 children with persistent hypertension seen over the past 5 1/2 years the commonest causes of hypertension were chronic glomerulonephritis, reflux nephropathy, coarctation of the aorta, and obstructive uropathy, accounting for some 70% of cases. 17 children have died, but in the remainder hypertension has been controlled by surgery, chronic haemodialysis, or by the use of pharmacological ...

Most of the research on sign language recognition concentrates on recognizing only manual signs (hand gestures and shapes), discarding a very important component: the non-manual signs (facial expressions and head/shoulder motion). We address the recognition of signs with both manual and non-manual components using a sequential belief-based fusion technique. The manual components, which carry in...

Many modern wireless networks integrate carrier sense multiple access/collision avoidance (CSMA/CA) with exponential backoff as medium access control (MAC) technique. In order to decrease the MAC overhead and the collision probability, we propose in this paper a new backoff strategy leading to better saturation throughput and access delay performance comparing to the classical protocol. We inve...

The meaning and mathematical consequences of linearity (managing without a presumed ability to copy) are studied for a path-based model of processes which is also a model of affine-linear logic. This connection yields an affine-linear language for processes, automatically respecting open-map bisimulation, in which a range of process operations can be expressed. An operational semantics is provi...

This paper presents a set of experiments aiming to (1) assess the contribution of NLP to the specific issue of the readability of texts for French as a foreign language (FFL) readers and (2) to propose a new readability formula for FFL. This new model relies on 46 textual features representative of the lexical, syntactic, and semantic levels as well as some of the specificities of the FFL conte...

This paper considers the improvment of speaker identification performance in reverberant conditions using additional lip information. Automatic speaker identification (ASI) using speech characteristics alone can be highly successful, however problems occur with mis-matches between training and testing conditions. In particular, we find that ASI performance drops dramatically when given anechoic...

Technical documentation is an important part of complex technical systems. As an information ressource, it is critical importance for the customer as well as for the producer. Consistence in content, interchangebility and reuse is essential. The more extensive and complex the technical documentation the more important is the content structuring. While techniques of structuring (and the separati...

Rodents, as mice and rats are the most common laboratory animals used in research and testing. They are seldom investigated for autochthonous ecto- and endoparasites prior their utilization in the experiments. Helminth parasites can alter the interpretation of final results. Pinworms commonly infecting laboratory rodents include mainly the mice pinworms Syphacia obvelata and Aspiculuris tetrapt...

Methods We retrospectively reviewed the case record of a fourteen year old boy of African origin with arthritis. He had been previously well and presented with a two week history of initially right ankle swelling which progressed to involve his left knee, right ankle, left wrist and distal interphalangeal joint of his index finger of his left hand. All these joints were swollen, warm and had re...
