acute injuries of the spine and spinal cord are among the most causes of severe disability and death after trauma. data about spine fracture with or without cord damage are different. the aim of this study was to determine epidemiology and demographics of spinal injury in main trauma center, guilan, an iranian province. the present study was a descriptive study of all cases of traumatic spine i...

This work presents a new approach to automatically answer definition questions from the Web. This approach learns n-gram language models from lexicalised dependency paths taken from abstracts provided by Wikipedia and uses context information to identify candidate descriptive sentences containing target answers. Results using a prototype of the model showed the effectiveness of lexicalised depe...

PURPOSE To describe an excimer laser ablation architecture called the pseudoaccommodative cornea (PAC) that uses ocular aberrometry and aspheric ablation profiles to create a multifocal cornea. METHODS A descriptive article outlining the theory of the PAC algorithm. RESULTS The topographic changes induced by PAC produce corneal multifocality. CONCLUSIONS PAC-treated eyes have progressive ...

We close the gap in complexity classification of the subsumption problem in the simple description logic FL0, which allows for conjunctions and universal value restriction only. We prove that subsumption in FL0 is PSPACE-complete when cyclic definitions with descriptive semantics are allowed. Our proof uses automata theory and as a by-product the PSPACE-completeness of a certain decision proble...

As part of research towards the CoSMoS unified infrastructure for modelling and simulating complex systems, we review uses of definitional and descriptive models in natural science and computing, and existing integrated platforms. From these, we identify requirements for engineering models of complex systems, and consider how some of the requirements could be met, using state-of-the-art model m...

Black henbane (BH) or Hyoscyamus niger, has been used as a medicine since last centuries and has been described in all traditional medicines. It applies as a herbal medicine, but may induce intoxication accidentally or intentionally. All part of BH including leaves, seeds and roots contain some alkaloids such as Hyoscyamine, Atropine, Tropane and Scopolamine. BH has pharmacological effects like...
