In microsurgical procedures, surgeons need to perform complex operations on extremely small anatomy. Vitreoretinal surgery is one such complex surgery, where several new promising techniques are being developed, which require extraordinary control at sub-mm scales. For these reasons, micron (robotic aid) was developed to help surgeons gain better positioning accuracy, with active tremor cancell...

in this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (anfis) for canceling maternal electrocardiogram (mecg) in fetal electrocardiogram extraction (fecg).this technique is used to estimate the mecg present in the abdominal signal of a pregnant woman. the fecg is then extracted by subtracting the estimated mecg from the abdominal signal. p...

BACKGROUND The ideal timing of surgical management for hip fractures remains controversial. Currently, individual surgeon preference and departmental resources guide decision making regarding the use of emergency or planned operating lists for hip fracture surgery. We evaluated patient preference for emergency or planned surgery. METHODS 102 patients awaiting surgery for a hip fracture at a t...

OBJECTIVE This study compared two methods of booking elective surgery - booking from wait lists and pre-booking surgery dates at the time of decision to operate - in terms of cancellations of elective procedures and time to surgery. METHODS The authors conducted simulation experiments with group randomized design, in which the unit of allocation was the hospital and the units of analysis were...

BACKGROUND Case cancellation (CC) has significant impact on the efficiency of operating room (OR) management, which can be mitigated by taking preventive measures. In this study, using the data of the West China Hospital (WCH), we identified the effect of contributing factors and recommended hospital interventions to facilitate CC prevention. METHOD We conducted a retrospective review of 11,3...

in this work we consider conjugacy of elements and parabolic subgroups‎ ‎in details‎, ‎in a new class of artin groups‎, ‎introduced in an earlier work‎, ‎which may contain arbitrary parabolic subgroups‎. ‎in particular‎, ‎we find‎ ‎algorithmically minimal representatives of elements in a conjugacy class‎ ‎and also an algorithm to pass from one minimal representative to the others‎.

In this letter we comment on partial parallel interference cancellation as discussed in the above paper by Divsalar et al. The aforementioned work showed that by multiplying symbol estimates by a factor less than unity in early stages of cancellation, the performance of parallel cancellation can be improved relative to full (“brute force”) cancellation. In this letter we analyze the improvement...
