Screening for oral leukoplakia, an oral cavity cancer (OCC) precursor, could lead to earlier detection of OCC. However, the progression rate from leukoplakia to OCC and the benefits of leukoplakia screening for improving OCC outcomes are currently unclear. We conducted a case-cohort study of U.S. adults ages ≥65 years in the Surveillance, Epidemiology, and End Results (SEER)-Medicare linkage. W...

BACKGROUND The most appropriate device for tracheal intubation in patients with potential cervical spine injury remains controversial. We hypothesized that the Lo-Pro GlideScope (LP-G) videolaryngoscope would not cause significantly greater cervical spine movement than fibreoptic bronchoscopy even in the non-immobilized spine. METHODS Twenty-eight healthy adults requiring intubation for radio...

ÐMany recent studies [8], [10] have suggested that the optimistic concurrency control (OCC) protocols outperform the locking-based protocols in real-time database systems (RTDBS). However, the OCC protocols suffer from the problem of unnecessary transaction restarts that is detrimental to transactions meeting their deadlines. The problem is more intensified in mixed transaction environments whe...

This study attempts to investigate sociotechnical gaps in online collaborative consumption (OCC) to improve user experience and provide better design requirements. A new approach is proposed to evaluate usability and sociability of the OCC communities. The formation of social capital within OCC will also be studied to gain insights into design requirements. Due to its features as a community wh...

As technological advances are made in software and hardware, the feasibility of accessing information "any time, anywhere" is becoming a reality. In a mobile computing environment, a potentially large number of mobile and fixed users may simultaneously access shared data; . In this paper, we have addressed the problem and devised an effective OCC protocol with deferred adjustment of serializati...

The Wnt signaling pathway is hyperactivated in most colorectal cancers (CRC). Finding new regulators of this pathway represents the potential for cancer diagnosis or treatment. OCC-1 was initially reported as an up-regulated gene in colon carcinoma, without knowing its mechanism of action. Here, two novel transcript variants and an exonic microRNA that originated from the OCC-1 gene are reporte...

Novelty detection involves modeling the normal patterns for detecting any divergence from this behavior. Our recently proposed algorithm, Glabal&Local One Class Classifier (GLocal OCC), can solve this problem by maximizing the margin between the hyperplane and the origin through embedding the global information into the OCSVM framework. In this paper, we propose Linear Programming (LP) GLocal O...

One-class classification (OCC) algorithms aim to build classification models when the negative class is either absent, poorly sampled or not well defined. This unique situation constrains the learning of efficient classifiers by defining class boundary just with the knowledge of positive class. The OCC problem has been considered and applied under many research themes, such as outlier/ novelty ...
