For two list of dependent data X and Y, we want to test X < Y.
The pairwised t-test is inappropriate because it violates independence assumption.
Bootstrap or permutation can only be used when there the list of observations are long.
For our H2O2-LOH dataset, we have only 10 time points (H2O2 doses), so bootstrap and permutation is inappropriate as well.
W Wu suggests that Fisher's exact test can be applied for each time point, and then apply Bonferroni correction. We think 3/4 LOH suggest a positive dependence between 1/2 and 1/4 LOH.

fisher exact test in R, test with proportion input data (not working)
#Q: Does R's default fisher's exact test function handle proportion input data?
mat = matrix(nrow=2,ncol=2)
mat[1,1]=30
mat[2,2]=45
mat[1,2]=5
mat[2,1]=6
mat;
fisher.test(mat)
mat = mat/sum(mat)
mat;
fisher.test(mat)
#conclusion: NO. R's defaulty fisher.test() does not handle proportion input.

Measurement and Modeling of Drugs in Tissues (Organized in Cooperation with International Society of Anti-Infective Pharmacology (ISAP))

SESSION 044-C - Measurement and Modeling of Drugs in Tissues (Organized in Cooperation with International Society of Anti-Infective Pharmacology (ISAP))
| June 17, 2016, 12:45 - 4:15 PM | Westin, Grand Ballroom A |
Anti-infective pharmacokinetics and pharmacodynamic (PK/PD) modeling traditionally relies on serum or plasma concentration-time data to define exposure-response relationships. Data derived from the blood compartment may or may not accurately reflect target tissue data. This course aims to review current and novel approaches to better quantify target tissue PK/PD. An improved understanding of tissue PK/PD measurement and modeling can help to optimize dosage regimen selection for infections in accessible and restricted compartments.

019-WS - Genome-scale Metabolic Modeling of Environmental Isolates and Communities using the DOE Systems Biology Knowledgebase (KBase)
Itinerary
| June 16, 2016, 8:15 - 4:15 PM | BCEC, Meeting Room 252A |
The Department of Energy Systems Biology Knowledgebase (KBase, http://kbase.us ) is a software and data platform designed to meet the grand challenge of systems biology: predicting and designing biological function. KBase integrates data, tools, and their associated interfaces into one unified, scalable environment, so users do not need to access them from numerous sources or learn multiple systems in order to perform sophisticated systems biology analyses. Users can perform large-scale analyses and combine multiple lines of evidence to model plant and microbial physiology and community dynamics. KBase is the first large-scale bioinformatics system that enables users to upload their own data, analyze it (along with collaborator and public data), build increasingly realistic models, and share and publish their workflows and conclusions. KBase aims to provide a knowledgebase: an integrated environment where knowledge and insights are created and multiplied.

bioscreen C test run
=> Try to use USB adapter for the COM interface using the original installation. It did not work, because the EasyBioscreen software was configured to the old COM port.
=> Heat transfer tube were mixed with many bubbles. I left the lid screw open, and run the instrument for 25C incubation. After about 30 minutes, large bubbles disappeared. At the same time, I kept adding transfer liquid to fill the volume left by airs.

mixed -80 glycerol stocks at Spelman
Samples in two boxes were mixed. One box is yellow #101. The other is Microbiology lab.
Box 101 is my bacterials stocks. Microbiology stocks is probably also bacterials stocks.

Findings show cell cycle slowed down (cycle time increases dramatically) near the end of survival curve. The author did not quantify the mode of these increase. (The model of increase may be hard due to small number of observations).
