purpose: to evaluate the nature of obstruction in difficult irrigation after probing for congenital nasolacrimal duct obstruction (cnldo). methods: in a prospective interventional study, the nature of obstruction in 75 eyes of 68 children aged between 12 and 23 months with cnldo who had difficult irrigation after probing was evaluated. all patients underwent monocanalicular silicone intubation....

For the purpose of motor coordination, the nervous system faces a complex control problem, involving redundant degrees of freedom, nonlinear dynamics of limbs and actuators, noise, and perturbations. Models and architectures have been proposed to describe motor coordination in terms of computational processes, and identify possible simplifying strategies that would alleviate the workload of the...

Simple questions require small snippets of text as the answers whereas complex questions require inferencing and synthesizing information from multiple documents to have multiple sentences as the answers. The traditional QA systems can handle simple questions easily but complex questions often need more sophisticated treatment e.g. question decomposition. Therefore, it is necessary to automatic...

In this paper we present a readability assessment system for Basque, ErreXail, which is going to be the preprocessing module of a Text Simplification system. To that end we compile two corpora, one of simple texts and another one of complex texts. To analyse those texts, we implement global, lexical, morphological, morpho-syntactic, syntactic and pragmatic features based on other languages and ...

BACKGROUND Recent publications have indicated that there is a crisis in clinical research. The cost of an industry-led clinical trial is now estimated at some US$100e200 million, within which an average 25% of centres will recruit no patients. The median number of enrolment (entry) criteria in a drug trial is 49, with a median of 158 different trial procedures. The number of data items per pati...

complex culverts have a change of section (transition) at one or more positions along their lengths. the hydraulic performance cannot be estimated using simple culvert methods because the transition may change the control point. by modeling the flow through a transition as free flow, sluice flow, pipe flow and treating a complex culvert, as a series of simple culverts with the appropriate hydra...
