Abstract Aim Preoperative OGD in patients undergoing bariatric surgery, has been a subject for debate decades. The aim of this study is to evaluate the pathology pick up rate routine preoperative endoscopy Gastric Bypass surgery (LRYGB) our unit. Method Retrospective review patients’ records who underwent LRYBG unit from February 2009 March 2020. Patients were divided into two groups according ...

In this work, a linear DS-CDMA receiver utilizing soft feedback interference cancellation, is analyzed. To be able to meet diverse QoS requirements, we introduce a power control scheme that takes into account multi-QoS objectives, as well as the impact of imperfect interference cancellation. Our results are general and provide a framework for capacity comparison for many proposed linear success...

The performance of Time Warp parallel discrete event simulators can be a ected by the cancellation strategy used to send anti-messages. Under aggressive cancellation, anti-message generation occurs immediately after a straggler message is detected. This results in quick termination of potentially incorrect computations (event processing) when out-of-order event processing occurs. In contrast, l...

Successive interference cancellation (SIC) is a promising practical scheme for increasing the capacity of CDMA systems. The interference cancellation is never perfect, and the residual cancellation errors propagate because of the successive nature of the decoding. In fact, these residual errors are the principle capacity-limiting issue in SIC systems. Until now, the statistics of these errors h...

BACKGROUND Intraoperative transoesophageal echocardiography is increasingly used for guiding intraoperative management decisions during non-cardiac surgery. Transthoracic echocardiography (TTE) equipment and training is becoming more available to anaesthetists, and its point-of-care application may facilitate real-time haemodynamic management and preoperative screening. METHODS We conducted a...

Interference cancellation is widely used in a number of application such as acoustic and speech signal processing, data communication, biological signal acquisition etc. Many papers with different approaches have been reported to cancel interferences in biosignals. This paper provides a survey of existing methods for interference cancellation in ECG signal, FECG signal, EEG signal, and EMG sign...
