This paper introduces an electrical drives control architecture combining a fractional-order controller and a setpoint pre-filter. The former is based on a fractional-order proportional-integral(PI) unit, with a non-integer order integral action, while the latter can be of integer or non-integer type. To satisfy robustness and dynamic performance specifications, the feedback controller is designed by a loop-shaping technique in the frequency domain. In particular, optimality of the feedback system is pursued to achieve input-output tracking. The setpoint pre-filter is designed by a dynamic inversion technique minimizing the difference between the ideal synthesized command signal(i.e., a smooth monotonic response) and the prefilter step response. Experimental tests validate the methodology and compare the performance of the proposed architecture with well-established control schemes that employ the classical PIbased symmetrical optimum method with a smoothing pre-filter.

The Italian team from Verona,questions the place of total pancreatectomy(TP)as an alternative to pancreaticoduodenectomy(PD)in patients at high risk of pancreatic fistula in a monocentric retrospective study running from July 2017 to December 2019(1).A total of 702 patients were included,566 PD of which 101 were at high risk of pancreatic fistula(HR-PD),136 TP of which 86 were PD converted to TP(C-TP)for positive margin of pancreatic section for malignancy(49%),extensive vascular resection(14%)or technical reasons(27%)such as residual non-reconstructible pancreas/friable pancreas/microscopic Wirsung’s duct,10% for other reasons(bleeding......)Patients in the HR-PD group received externalized stent of the Wirsung duct.

In this paper, we are interested in answering the following research question: "Is it possible to form effective groups in virtual communities by exploiting trust information without significant overhead, similarly to real user communities?"In order to answer this question, instead of adopting the largely used approach of exploiting the opinions provided by all the users of the community(called global reputation), we propose to use a particular form of reputation, called local reputation. We also propose an algorithm for group formation able to implement the proposed procedure to form effective groups in virtual communities. Another interesting question is how to measure the effectiveness of groups in virtual communities. To this aim we introduce the index in a measure of the effectiveness of the group formation. We tested our algorithm by realizing some experimental trials on real data from the real world EPINIONS and CIAO communities, showing the significant advantages of our procedure w.r.t. another prominent approach based on traditional global reputation.

Diabetes affects approximately 30 million persons in the United States. Diabetes ketoacidosis is one of the most serious and acute complications of diabetes. At the time of presentation and during treatment of diabetic ketoacidosis(DKA), several metabolic and electrolyte derangements can ultimately result in respiratory compromise. Most commonly, hypokalemia, hypomagnesemia and hypophosphatemia can eventually lead to respiratory muscles ***, tachypnea, hyperpnea and more severely, Kussmaul breathing pattern can develop. Also, hydrostatic and non-hydrostatic pulmonary edema can occur secondary to volume shifts into the extracellular space and secondary to increased permeability of the pulmonary capillaries. The presence of respiratory failure in patients with DKA is associated with higher morbidity and mortality. Being familiar with the causes of respiratory compromise in DKA, and how to treat them, may represent better outcomes for patients with DKA.

Thank you for inviting us to comment the review article entitled"Use of robotics in liver donor right hepatectomy"by Chen PD et al.(1),published on HBSN *** their interesting paper,the authors stated that despite the fact that minimally invasive surgery(MIS)has been documented with safety and feasibility in complex liver surgery the progress has been slow in regard to the application of MIS in donor graft *** surgeons have devoted themselves to develop pure MIS approach for donor hepatectomy,but the steep learning curve remains barrier for its wide *** authors suggest that the introduction or robotic assisted surgery may contribute to a wider acceptance of MIS as the technique of choice for live donor *** a great attention to donor selection and continuous improvement in donor care the risks of donor hepatectomy remain real and the complication rate not insignificant(2).Traditional open liver resection results in post-operative pain and in at least 30%of the cases these pains were attributed to abdominal wall trauma(1,2).For these reasons and with the aim of facilitating donor recovery,transplant surgeons have been exploring the possibility of routinely applying MIS to live donor *** bridge the gap between open and pure MIS donor procurement,hand-assisted laparoscopic surgery was initially introduced in the 90'.It was not until 2002 that Soubrane O presented the first two cases of pure laparoscopic left lateral living donor hepatectomy,followed in the years to come by several successful attempts to extend the procedure to the procurements of full left and right hepatic lobes(1-6).

Wind power is one of the fastest-growing renewable energy sectors instrumental in the ongoing decarbonizationprocess. However, wind turbines are subjected to a wide range of dynamic loads which can cause more frequentfailures and downtime periods, leading to ever-increasing attention to effective Condition Monitoring *** this paper, we propose a novel unsupervised deep anomaly detection framework to detect anomalies in windturbines based on SCADA data. We introduce a promising neural architecture, namely a Graph ConvolutionalAutoencoder for Multivariate Time series, to model the sensor network as a dynamical functional graph. Thisstructure improves the unsupervised learning capabilities of Autoencoders by considering individual sensormeasurements together with the nonlinear correlations existing among signals. On this basis, we developeda deep anomaly detection framework that was validated on 12 failure events occurred during 20 months ofoperation of four wind turbines. The results show that the proposed framework successfully detects anomaliesand anticipates SCADA alarms by outperforming other two recent neural approaches.
