We consider the problem of creating plane orthogonal drawings of 4-planar graphs (planar graphs with maximum degree 4) with constraints on the number of bends per edge. More precisely, we have a flexibility function assigning to each edge e a natural number flex(e), its flexibility. The problem FLEXDRAW asks whether there exists an orthogonal drawing such that each edge e has at most flex(e) be...

FLEX is a user interface to relational databases that is tolerant of incorrect input. FLEX never rejects a query; instead, it adjusts to the level of technical expertise its users seem to possess (as judged from their input). In particular, FLEX understands formal queries; salvages incorrect queries if they include enough clues on their intended meaning; suggests educated guesees if it recogniz...

FLEX is a new scalable “locality aware” solution for achieving both load balancing and efficient memory usage on a cluster of machines hosting several web sites. FLEX allocates the sites to different machines in the cluster based on their traffic characteristics. This aims to avoid the unnecessary document replication to improve the overall performance of the system. The desirable routing can b...

This prospective randomized study compares the long term results between total knee arthroplasty with a mobile bearing high flex and a fixed bearing posterior stabilized knee (LPS) in 39 patients. The Hospital for Special Surgery score (HSS) was calculated and radiographs in AP and lateral view were analyzed after a minimum follow-up of 10 years. No significant differences between the two group...

PURPOSE To characterize the clinical profile of femtosecond lenticule extraction (FLEx) correlated with ultrastructural analysis of the corneal interface and in vivo real-time intraocular pressure (IOP). METHODS Prospective clinical case series with experimental studies; consecutive patients underwent FLEx at a single tertiary center over 10 months with postsurgical follow-up of 3 months. The...

PURPOSE The purpose of this study was to compare postoperative range of motion and functional outcomes among patients who received high-flexion total knee arthroplasty using cruciate-retaining (CR-Flex) and posterior-stabilized (PS-Flex) type prostheses. MATERIALS AND METHODS Among 127 patients (186 knees) who underwent high-flexion total knee arthroplasty between 2005 and 2007, 92 knees were...

STUDY OBJECTIVES To compare adherence and clinical outcomes between flexible positive airway pressure (PAP) [C-Flex; Respironics; Murraysville, PA] and standard PAP therapy (ie, continuous positive airway pressure [CPAP]). DESIGN AND SETTING A controlled clinical trial of CPAP therapy vs therapy using the C-Flex device in participants with moderate-to-severe obstructive sleep apnea. Participa...

INTRODUCTION Accelerometers are commonly used to assess physical activity. Consumer activity trackers have become increasingly popular today, such as the Fitbit. This study aimed to compare the average number of steps per day using the wrist-worn Fitbit Flex and waist-worn ActiGraph (wGT3X-BT) in free-living conditions. METHODS 104 adult participants (n = 35 males; n = 69 females) were asked ...
