The computer program is prepared for applying Montecarlo simulation and modeling for single-electron nanocrystal memories. The nanocrystal memory device of (5×5) quantum dots is used for studying the relationship between, geometrical dimensions, electrical characteristics and charging effects for single electron static programming characteristics. The nanocrystal inter-dot effects are included. All parameters got in the memory simulation programming are studied and discussed.

Objectives: Superficial swellings in the head and neck region pose great difficulties in deciding about their nature. Fine needle aspiration cytology (FNAC) is of great help in the initial assessment of these lesions. The aim of the article is to help the surgeons in diagnosis of pleomorphic adenoma in line with clinical information. Study Design: Retrospective analysis. Setting: Histopathology lab of PMC. Period: 2016 to 2018. Materials and Methods: 60 aspirates of pleomorphic adenoma recruited. All cases were reviewed independently by two pathologists for cytomorphological findings. Results: Spindle shaped myoepithelial cells were more frequently observed in 78% followed by epithelioid 20% and plasmacytoid 1.7% variants. Duct formation was seen in 81.6% and myxoid background in 88.3% aspirates. Out of total 60 cytological smears 56.6% were cellular and 13.3% were hypocellular. In 30% cases the smears showed predominant matrix. Conclusion: Our study concludes that cytomorphological features on FNAC in the light of clinical findings can greatly help the surgeons in management of the patients with salivary gland tumors.
