Early on in this afternoon's earnings call, Cook touched on the success of the iPad with a passing prediction, saying that he "still believe[s] it will be larger than the PC market" in the long run.
Algorithm of PASS predictions is described in detail in several publications [21, 22, 23, 24].
In predefined workflows we start with an SDFile, filter the structures by substructure queries, followed by PASS predictions [2].
PASS predictions are based on SAR analysis of the training set consisting of more than 900000 of drugs, drug-candidates and lead compounds.
On the basis of exhaustive literature review and PASS predictions, it has been found that substituted 1,2,3,4 tetrahydropyrimidine derivatives have good potential to exhibit in vitro anti-inflammatory activity.
As the PASS tool interprets the BAS based on the 2D structure of molecules, the hemiacetalic ("cyclic") and dialdehidic ("open") structures of OA and DOA were drawn using ACD/ChemSketch version 12, then saved as MDL Molfiles (*.mol) and directly uploaded into the PASS prediction program to predict the biologically active spectra of the molecules.
Not only do they retain many predictions passing through a filter requiring predictions to be present in 3 or more databases (79 %, 64, 57% respectively) (Figure 1D), they also perform well when evaluating database performance on both precision and recall when compared to publicly available high-throughput microarray data (Figure 2C).
2In the literature [15,26], noncausal predictive methods have been used for the IPE by using multi-passes prediction for multi-layers embedding.
PASS prediction of the compound, Pa represents probability to be active and Pi represents probability to be inactive.
The results of PASS prediction for a compound are demonstrated as a list of activity names and probability activity (P a) values.
During execution of the workflow, the PASS (Prediction of Activity Spectra of Substances) program [3] is used to calculate prediction coefficients for around 3000 biological activities for both the structures with known and unknown' activity.
