an aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation) direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation) direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometr...
The Chemical-mechanical polishing (CMP) process is now widely employed in the ultra-large-scale integrated semiconductor fabrication. Due to the continuous decrease in the sub-micron feature size, characterization of erosion has become an important issue in Cu CMP. In this paper, the erosion in Cu CMP is considered at two levels: wafer and die levels. Erosion models are developed based on the m...
Tracheostomy is used to obtain airway access to allow for mechanical ventilation in experimental animal models. We present a microsurgical atlas of our technique for tracheostomy in the adult rat.
OBJECTIVE To design a probability model for prolonged mechanical ventilation (PMV) using variables obtained during the first 24 hours of the start of MV. DESIGN An observational, prospective, multicenter cohort study. SCOPE Thirteen Spanish medical-surgical intensive care units. PATIENTS Adult patients requiring mechanical ventilation for more than 24 hours. INTERVENTIONS None. STUDY ...
We extend the concept of Named Entities to Named Events – commonly occurring events such as battles and earthquakes. We propose a method for finding specific passages in news articles that contain information about such events and report our preliminary evaluation results. Collecting “Gold Standard” data presents many problems, both practical and conceptual. We present a method for obtaining su...
