Charles L. A. Clarke Gordon V. Cormack Forbes J. Burkowski Dept. of Computer Science University of Waterloo, Waterloo, Canada, N2L 3G1 Technical Report CS-94-40 November 23, 1994 Abstract We describe data structures and an update strategy for the practical implementation of inverted indexes. The context of our discussion is the construction of a dedicated index engine for a distributed full-tex...

Involvement of cervical spine in ankylosing spondylitis limits neck movement resulting in difficult intubation. We report a case of 45-yr-old lady of ankylosing spondylitis with restricted neck movement planned for emergency laparotomy. Grade 3 Cormack and Lehane laryngoscopic view was observed with Macintosh laryngoscope and gum elastic bougie could not be negotiated. At second attempt with Mc...

Estimation of demographic parameters is central to research questions in wildlife management, conservation, and evolutionary ecology. I review the 7 major classes of mark–recapture models that investigators can use to estimate apparent survival and other parameters from live-encounter data. Return rates are the product of 4 probabilities: true survival (S), site fidelity (F), site propensity (d...

BACKGROUND Airway management is critical in patients with cervical spondylosis, a population with a high incidence of difficult airway. Intubation with Shikani Optical Stylet (SOS) has become increasingly popular in difficult airway. We compared the effects of intubation with SOS versus Macintosh laryngoscope (MLS) in patients undergoing surgery for cervical spondylosis. METHODS A total of 27...

AIM To determine the accuracy of the modified Mallampati test for predicting difficult tracheal intubation. DESIGN A cross-sectional, clinical, observational, non-blinded study. A quality analysis of anesthetic care. SETTING Operating theatres and department of anesthesiology in a university hospital. MATERIAL AND METHODS Following the local ethics committee approval and patients' informe...

Background: This study assesses the effectiveness of the GlideScope Videolaryngoscope (GS) in comparison with the Macintosh laryngoscope in a simulated difficult airway with blood in the airway and restricted range of motion of the neck. 39 participants experienced with the GS and the Macintosh laryngoscope were used. Methods: This analysis is a prospective, randomized, crossover study. Our stu...

This article introduces Rcapture, an R package for capture-recapture experiments. The data for analysis consists of the frequencies of the observable capture histories over the t capture occasions of the experiment. A capture history is a vector of zeros and ones where one stands for a capture and zero for a miss. Rcapture can fit three types of models. With a closed population model, the goal ...

Abstract Contemporary digital in ear hearing aids are of significant importance for social participation users with impairments. Through the advancement technology, extreme miniaturisation these devices has been achieved. However, by no means all people who could benefit from a aid actually use one. Cormack and Fortnum state that majority (80%) adults aged 55–74 years would aid, do not them. Th...

Background: Glidescope® video laryngoscope (GVL) is widely used in tracheal intubation. However, no studies have been conducted to compare the GVL and Macintosh direct laryngoscope (MDL) for intubation in patients with laryngeal neoplasm. Here, we aim to compare GVL and MDL for the intubation of laryngeal neoplasm patients. Methods: One hundred ninety-six American Society of Anesthesiology (ASA...
