This paper explores two classes of model adaptation methods for Web search ranking: Model Interpolation and error-driven learning approaches based on a boosting algorithm. The results show that model interpolation, though simple, achieves the best results on all the open test sets where the test data is very different from the training data. The tree-based(More)
Background: Chronic kidney disease (CKD) has been linked to serious arrhythmias. We studied the impact of CKD upon implantable cardioverter-defibrillator (ICD) recipients. Methods and Results: Baseline estimated glomerular filtration rate (eGFR) was calculated from variables at the time of ICD implantation in 95 patients. Patients with eGFR below 60 ml/min(More)
Among the factors that control the survival of microorganisms on human stratum corneum are skin lipids, including sphingosines. Because the antibacterial spectrum of sphinganine resembles that of cell wall antibiotics, electron microscopy of sphinganine-treated and untreated S. aureus was performed; the lipid induced multiple lesions of cell wall, membrane(More)
PURPOSE The purpose of this study was to investigate the cumulative survival rates of dental implants placed in a private periodontal practice and the effects of periodontal disease and immediate placement on implant survival. MATERIALS AND METHODS A retrospective chart review was conducted on 149 consecutive patients. Each patient had a single implant(More)
Type III collagen (Col3), a fibril-forming collagen, is a major extracellular matrix component in a variety of internal organs and skin. It is also expressed at high levels during embryonic skeletal development and is expressed by osteoblasts in mature bone. Loss of function mutations in the gene encoding Col3 (Col3a1) are associated with vascular(More)
Tumor necrosis factor alpha (TNF alpha) antagonists are biologic agents used in the management of inflammatory conditions such as rheumatoid arthritis, seronegative spondyloarthropathies and inflammatory bowel disease. These agents have been recently shown to cause a syndrome called anti-TNF induced lupus (ATIL), a rare condition which has similar clinical(More)
Despite advances in our understanding of the human speech system, the neurophysiological basis of stuttering remains largely unknown. Here, it is hypothesized that the speech of adults who stutter (AWS) is susceptible to disruptions in sensorimotor integration caused by neural miscommunication within the speech motor system. Human speech unfolds over rapid(More)
The term Big Data is usually used to describe huge amount of data that is generated by humans from digital media such as cameras, internet, phones, sensors etc. By building advanced analytics on the top of big data, one can predict many things about the user such as behavior, interest etc. However before one can use the data, one has to address many issues(More)
INTRODUCTION Late revision nerve surgery for incomplete motor recovery due to partial reinnervation would improve muscle function if all muscle fibers were protected from developing denervation atrophy. METHODS Sixty immature Sprague-Dawley rats underwent the following tibial nerve manipulations (n = 15/group): group A, partial denervation (two thirds of(More)
PURPOSE To evaluate the efficacy and safety of the accelerated partial breast irradiation brachytherapy with a combination of applicators at a community hospital cancer center. METHODS AND MATERIALS Between 2005 and 2009, 120 patients with early-stage breast cancer were being followed after treatment with accelerated partial breast irradiation(More)
