Introduction Using Drosophila, the goal of this lab was to study and identify the genetics behind certain traits through to use of dihybrid crosses. With the crosses, the purpose was to find the different dominant and recessive traits in the eyes and wings of the Drosophila. Flies were used to study the genetics as opposed to other insects or animals because they are easy to mass-produce and the traits, when viewed under a microscope, are easily identifiable. The hypothesis was that the traits…

Implementation of Bayesian Method for basic pattern Classification Abstract: This document describes an example of basic pattern classification using the Bayesian method. Based on given two dimensional (2-D) training data for two classes, we created a classifier using discriminant function (which is the logarithmic version of Bayes formula) and used it to classify provided test data. We estimated the necessary statistical parameters, such as mean covariance and prior probabilities, from…

that, for any such plurality P, there is a form of F-ness by virtue of partaking of which each member of P is F, it follows that there is one form over the many members of P” (Stanford Para number). Lets consider the following class of variables; x1, x2, and x3, there exists…

Altman Z-Score The Altman Z-score is the output of a credit-strength test that gauges a publicly traded manufacturing company's likelihood of bankruptcy. The Altman Z-score is based on five financial ratios that can be calculated from data found on a company's annual report. It uses profitability, leverage, liquidity, solvency and activity to predict whether a company has a high degree of probability of being insolvent. Altman Z-Scores and the Financial Crisis In 2007, the credit ratings of…

solving authentic problems using digital tools and resources. The activity was followed by developing students’ conceptual understanding of slope intercept form. With the prices fresh in my students’ minds, we came up with slope’s formula of y2 – y1 over x2 – x1 or the prices of 4 toppings subtracted by the price of 2 toppings over the difference in the number of toppings. They projected the lines until they get the y-intercept. Students checked the validity of their equations using Desmos…

hundred patients were included in this study. The model fit was achieved adequately (P value=0.741). The area under the ROC curve was 0.773 (95%CI: 0.65-0.92) and standardized mortality ratio was 1.08.PIM2 calibrated well using Hosmer Lemeshow analysis (X2=5.58 ,P=0.34). The expected deaths were 34% and the observed deaths were 37%. The expected /observed ratio is 0.91 Conclusion: PIM2 can be used as a good prediction model for pediatric mortality and as a tool for assessing the overall quality…

RESULTS AND DISCUSSION The discussion will cover the obtained results under the following heads: 1. Effect of some different parameters on the behavior of drying rate Fig.1 showed the relation between drying rate and drying time under two drying methods of fruits peels. It was cleared that the drying rate decreased continuously with drying time. There was not any constant-rate drying period and all the drying operations are seen to occur in the falling rate period. The drying rates were higher…

Medical History: A 72--year-old African American male with a history of CKD stage 5 in the setting of longstanding hypertension, possible polycystic kidney disease, BPH, obesity, who presents for evaluation for candidacy for a kidney transplant. The patient has been evaluated recently at Shands Hospital for kidney transplant, but his evaluation was not completed due to obesity and possible cardiac problems. Renal History: The patient has longstanding history of chronic kidney disease in the…

floor, but others require that the doctor remove it. Before removal, the nurse should assess the clotting time for the patient. Generally, vital signs and distal pulses should be taken every fifteen minutes X 4, every thirty minutes X 2, and every hour X2, then routine (every hour). If there is any change in the patient’s neurovascular status the physician should be notified…

Alphonse Allais mentions, “Statistics have shown that mortality increases perceptibly in the military during wartime” (Statistics Quotes, 2). The author, Stephen M. Stigler, written the book title “The History of Statistics: The Measurement of Uncertainty before 1900”, expressing the beginnings of statistics between the years 1700 to 1900. Stigler demonstrated how the roles of statistics play in applied sciences of “astronomy, geodesy, experimental psychology, genetics, and sociology” (Stigler…
