The biomechanics of the knee do not return to normal after knee replacement. The purpose of this scoping review is to summarize the current use of gait analysis in total knee arthroplasty and to identify the preoperative motion analysis parameters for which a systematic review aimed at determining the reliability and validity may be warranted.This IRB-exempt scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. The 279 articles from the five search engines underwent a title/abstract and full-text screening. Included articles were categorized as either: the role of gait analysis as a research tool for operative decisions, other research applications for motion analysis in total knee arthroplasty, gait analysis as a tool in predicting radiologic outcomes, or gait analysis as a tool in predicting clinical outcomes.Eleven articles studied gait analysis as a research tool in studying operative decisions. Five articles studied other research applications for motion analysis in total knee arthroplasty. Other research applications for motion analysis currently include studying the role of the unicompartmental knee arthroplasty and novel physical therapy protocols aimed at optimizing post-operative care. Two articles studied motion analysis as a tool for predicting radiographic outcomes. 15 articles studied motion analysis in conjunction with clinical scores.There is a broad range of research applications for motion analysis in knee reconstruction. Current limitations include vague definitions of 'gait analysis' or 'motion analysis' and a limited number of articles with preoperative and postoperative outcomes. Knee adduction moment, knee adduction impulse, total knee range of motion, varus angle, cadence, stride length, and velocity have the potential for integration into composite clinical scores. A systematic review to determine the psychometric properties of these variables is warranted.

In subsea applications there are an increasing demand for Remotely Operated Vehicles (ROV’s). This study examines a BlueROV2 inspection ROV prototype for autonomous operation in three-dimensional space. This study describes the ROV modelling, identification, control development and closed-loop simulations and experiments. The main transmitter applied for the navigation is an Underwater Acoustic Positioning System (UAPS) which acts as an underwater GPS unit. The transmitter introduces a dominant output time delay which is handled by a smith predictor. The results show that the smith predictor does not handle the time delay well, probably because the time delay is time-variant. Online identification of the time delay is proposed as a potential solution for minimizing the impact of the time delay variations over time.

OBJECTIVES Anemia is the most frequent extra-intestinal finding in inflammatory bowel disease (IBD). The aim of this study is to determine the prevalence and types of anemia in pediatric patients with IBD at diagnosis and at approximately 1 year follow-up. METHODS This is a retrospective chart review of patients diagnosed with IBD from 2005 to 2012, ages 1 to 18 years. Patients who had hemoglobin, hematocrit, mean corpuscular volume, and iron indices obtained at the time of diagnosis and at approximately 1 year follow-up were included in the study. The prevalence of anemia at the beginning and the end of the study was recorded. Using the soluble transferrin receptor index the type of anemia was determined. RESULTS At diagnosis, 67.31% of patients were anemic. Overall, 28.85% of patients had either iron deficiency anemia (IDA) or a combination of IDA and anemia of chronic disease (ACD), whereas 38.46% had ACD alone. At follow-up, 20.51% were anemic. 15.38% had either IDA or a combination of IDA and ACD; 5.13% had ACD alone. The pattern of anemia and response to therapy differed among the IBD phenotypes CONCLUSIONS:: Anemia is frequent in inflammatory bowel disease. The prevalence was higher in Crohn disease (CD). At 1 year, the prevalence of anemia decreased significantly, but persisted. Anemia of chronic disease predominated in CD. Iron deficiency anemia continued to be present in CD and ulcerative colitis.

Failures in pitch systems may cause fatal damage to industrial wind turbines. One of the main reasons for failures in pitch systems is gas leakages of hydraulic accumulators. Due to the limited accessibility of offshore turbines, automated fault detection algorithms potentially increase turbine availability. The gas leakage is detected without downtime by using a model-based approach together with a bank and extended Kalman filters (EKF’s). The residual is analyzed using multi-model adaptive estimation (MMAE). The applied accumulator model relies on a thermal time constant describing the heat flux from the gas to the surroundings. The thermal time constant has been empirically derived from a prepressure of 50 to 172 bar. The fault detection algorithm is tested experimentally in a laboratory on a 25 liters piston accumulator using a load scenario obtained from real turbine data and a prepressure range of 50–140 bar. The Bank of EKF’s can classify the prepressure within a range and thereby detect if a gas leakage has occurred before it results in failure.

Peer review of manuscripts for potential publication has become an intrinsic component of the scientific process, and is aimed at improving the manuscript's quality through unbiased, independent, and critical assessment by experts who are not on the journal's staff (International Committee of Medical Journal Editors, 2003).

Data were obtained from the tax records and the Professional Registry maintained by the New York City Department of Health as well as from the Biographical Directory of the American Psychiatric Association to determine which psychiatrists were providing care under the Medicaid Program and how they compare with the pool of psychiatric practitioners in New York City. The data reveal that psychiatrists educated in foreign medical schools provide disproportionately more care to Medicaid recipients than would be anticipated from their numbers, and are a majority of those who received more than $30,000 in payments in 1976. Furthermore, these psychiatrists account for 80 per cent of those delivering care at the two largest "shared health facilities," commonly referred to as "Medicaid mills." These findings indicate that although the Title XIX Program has facilitated the access of the poor to the private psychiatric sector, in New York City their access is biased toward treatment by foreign-educated psyc...
