The drone market’s growth poses a serious threat to the negligent, illicit, or non-cooperative use of drones, especially in airports and their surroundings. Effective protection of an airport against drone intrusions should guarantee mandatory safety levels but should also rely on a resilience-driven operational concept aimed at managing the intrusions without necessarily implying the closure of the airport. The concept faces both safety-related and security-related threats and is based on the definitions of: (i) new roles and responsibilities; (ii) a set of operational phases, accomplished by means of specific technological building blocks; (iii) a new operational procedure blending smoothly with existing aerodrome procedures in place. The paper investigates the evaluation of such a resilience-driven operational concept tailored to drone-intrusion features, airport features, and current operations. The proposed concept was evaluated by applying it to a concrete case study related to Milan Malpensa Airport. The evaluation was carried out by real-time simulations and event tree analysis, exploiting the implementation of specific simulation tools and the assessment of resilience-oriented metrics. The achieved results show the effectiveness of the proposed operational concept and elicit further requirements for future counter-drone systems in airports.
Some cases of successful pregnancy after conservative endometrial cancer management have been reported. This paper presents such a case, an infertile patient with conservatively treated endometrial cancer (stage 1a grade 1) who conceived and carried a successful pregnancy after IVF treatment. The conservative treatment consisted of hysteroscopic biopsies and oral megestrol acetate 600 mg daily for 3 months. At the end of the treatment the endometrial cancer remitted to simple endometrial hyperplasia. IVF was performed immediately and 32 days after embryo transfer an intrauterine single gestational sac with fetal pole and heartbeat was detected by transvaginal ultrasound. The woman received routine obstetric care and a caesarean section was performed at 38 weeks of gestation. The histological evaluation after delivery showed no evidence of recurrent disease. Twenty-six months after the delivery, the woman is healthy and free of the disease. It is concluded that conservative treatment of stage 1a and grade 1 endometrial adenocarcinoma is an available option in young women who wish to preserve their fertility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
