Performance-enhancing mechanisms in the World Wide Web primarily exploit repeated requests to Web documents by multiple clients. However, little is known about patterns of shared document access, particularly from diverse client populations. The principal goal of this paper is to examine the sharing of Web documents from an organizational point of view. An(More)
In overloaded task systems, it is by de nition not possible to complete all tasks by their deadlines. However it may still be desirable to maximize the number of in-time task completions. The performance of on-line schedulers with respect to this metric is investigated here. It is shown that in general, an on-line algorithm may perform arbitrarily poorly as(More)
While algorithms for cooperative proxy caching have been widely studied, little is understood about cooperative-caching performance in the large-scale World Wide Web environment. This paper uses both trace-based analysis and analytic modelling to show the potential advantages and drawbacks of inter-proxy cooperation. With our traces, we evaluate(More)
OBJECTIVE To present robotic repair of vesicouterine fistulae (VUF) with and without hysterectomy in 3 cases and to discuss the technique with its outcome. METHODS Three patients were diagnosed with VUF, of whom 2 had a prior history of multiple cesarean sections and 1 had obstructed labor. Preoperative diagnosis of VUF was based on classic history,(More)
AIM To determine the diagnostic reliability of 18F-FDOPA, 13N-Ammonia and 18F-FDG PET/CT in primary brain tumors and comparison with magnetic resonance imaging (MRI). MATERIALS AND METHODS A total of 23 patients, 8 preoperative and 15 postoperative, undergoing evaluation for primary brain tumors were included in this study. Of them, 9/15 were operated for(More)
OBJECTIVES To assess the efficacy of nuclear matrix protein 22 (NMP-22) in the diagnosis of recurrent, superficial bladder cancer and whether it can predict for future recurrence. METHODS Patients with diagnosed and treated superficial transitional cell carcinoma urinary bladder (Stage Ta, T1, Tis, Nx, and M0) presenting for surveillance follow-up were(More)
PURPOSE To evaluate the role of age, Gleason score, prostate-specific antigen (PSA), PSA doubling time (PSADT), and PSA half-time (PSAT(1/2)) as prognostic factors in metastatic prostate cancer to predict long-term outcome. PATIENTS AND METHODS 412 patients with metastatic prostate cancer diagnosed after January 1995, with at least 6 months of follow-up,(More)
Vehicular Ad-hoc Network (VANET) is a collection of communication vehicles, moving in different directions. The vehicles form a communication group to disseminate desired information. Various routing protocols are implemented in a VANET, each having benefits and shortcoming in the domain of implementation. In this paper performance of three routing(More)
Tourniquets are commonly used in limb surgeries, be it orthopedic or plastic surgeries. But the inflation pressures, the duration, and release guidelines are still not clear. According to a survey, majority of orthopedic surgeons inflate the tourniquet to fixed pressures for the upper and the lower limbs without considering the baseline blood pressure of(More)
