There is a general concern that the increasing penetration of electric vehicles(EVs)will result in higher aging failure probability of equipment and reduced network *** electricity costs may also increase,due to the exacerbation of peak load led by uncontrolled EV *** paper proposes a linear optimization model for the assessment of the benefits of EV smart charging on both network reliability improvement and electricity cost *** objective of the proposed model is the cost minimization,including the loss of load,repair costs due to aging failures,and EV charging *** proposed model incorporates a piecewise linear model representation for the failure probability distributions and utilizes a machine learning approach to represent the EV charging *** two different test systems(a 5-bus network and the IEEE 33-bus network),this paper compares aging failure probabilities,service unavailability,expected energy not supplied,and total costs in various scenarios with and without the implementation of EV smart charging.

To the Editor: As we all know, even with the current advancements regarding novel chemotherapy regimens, patients affected by pancreatic cancer(PC) have an extremely dismal prognosis(5-year survival rate 12% for all stages in the National Cancer Institute SEER database). Among the patients undergoing surgical treatment, the prognosis is mostly affected by recurrence. PC after surgery has mainly four patterns of recurrence, isolated or variously associated with each other: local, lymph nodal, peritoneal or distant(liver, lung, other sites).
