Background: Lung cancer has long been a leading cause of cancer related death in both women and men worldwide. The focus of this study was to review clinicopathological features of Iranian patients diagnosed with lung cancer. Materials and Methods: Clinicopathological data of 1353 primary lung cancer patients diagnosed during 17 years (1997-2014) in the "National Institute of Tuberculosis and Lung Disease" (NRITLD), Tehran, Iran, were retrospectively reviewed. Results: The median age of patients was 60 (mean: 58.95 years, range: 16-99) and adenocarcinoma was the most prevalent pathology (45.2%). Male/female ratio was 3.22 and 57.2% of patients were smokers (men 70.3%, women 15%). The majority (85.3%) were referred in advanced stages (stage IIIB and IV). Conclusions: Although some of our findings are in concordance with other studies in lung cancer but there are some discrepancies particularly in terms of smoking status and median age of Iranian patients. Further clinical and epidemiological studies are warranted to elucidate etiologic and factors other than smoking contributing to development of lung cancer such as environmental exposures or genetic predisposition.

Advanced logic gates and transistor technologies play a crucial role in the design of high-speed computing systems. In this paper, a novel 3-dimensional fin-shaped reconfigurable transistor is presented, which exhibits identical behavior in both n-enhancement mode and p-enhancement mode operations. The key highlight of this reconfigurable transistor lies in its ability to integrate XNOR, NOT, and AND gates within a single device. Unlike conventional reconfigurable transistors, the proposed device incorporates a dual-doped n+/p+ source and a Schottky drain region. Notably, this device only requires a control gate, while the drain electrode serves the dual purpose of being the output and program gate. The findings demonstrate remarkable performance characteristics for the n-enhancement mode and p-enhancement mode operations. Specifically, the on-state current is measured to be 3.68 µA and 2.85 µA, with corresponding on/off current ratios of 11.25 × 108 and 1.23 × 108, respectively. Moreover, the device achieves a subthreshold swing of 61 mV/dec and 63 mV/dec for the n-enhancement mode and p-enhancement mode, respectively. This innovative design highlights the potential of utilizing a single FinFET recon f igurable transistor to design complex logic gates, demonstrating a significant advancement in integrated circuit technology towards enhanced efficiency and versatility.

Recent years have seen a rapid development in industrialization and urbanization with a huge growth inthe population throughout the world. In this regard, an efficient and robust decision-making frameworkfor the concept of a green city and sustainable development goals to manage municipal plastic wastes isstill needed. This study models a bio-recovery of municipal different plastic wastes management basedon a new integrated Multi-Criterion Decision-Making (MCDM) approach through a case study inMashahd, Iran. The proposed integrated MCDM framework includes the Shannon Entropy (SE),Ordered Weighted Aggregation (OWA), Analytic Hierarchy Process (AHP), Technique for OrderPreference by Similarity to Ideal Solution (TOPSIS) and, ELimination Et Choice Translating REality(ELECTRE) systems in an intelligent way. Through decision-making computations, all criteria areapproved after extraction from the literature review by experts with more than 60% agreement percentage. Different scenarios of economic, energy, and environmental crises are created. One finding of thispaper is to propose a new entrance in economic competition with plastic biodegradation to present anovel, environmental-friendly product with high-quality and low-cost advantages. Another findingdetermines that with an application of plastic wastes bio-recovery, citizens’ satisfaction from urban managementsystem will be increased from 49% to 64%. Whereas, based on the outcomes of this investigation,the rate of municipal waste industries development, smart city goals’ meeting, and rate of hazardousmaterial emission from municipal solid wastes are increased to 58%, 25%, and 70%, respectively. Thedeclared numerical outcomes illustrate the effectiveness of plastic waste bio-recovery on the smart cityconcept.
