Predicting Products: Substitution vs. Elimination

12.5K
When a nucleophile and an alkyl halide react, nucleophilic substitution and β-elimination reactions compete to generate products.
The following factors can influence the mechanisms competing against each other:

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

117
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

Survival Tree01:19

Survival Tree

178
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

  • To enable generalization of the SuStaIn algorithm to novel modeling scenarios.

Main Methods:

  • Implementation of the Subtype and Stage Inference (SuStaIn) algorithm in a Python package.
  • Utilizing cross-sectional data to infer multiple disease progression patterns (subtypes) and individual severity (stages).
  • Development of a consistent architecture supporting extension and generalization.

Main Results:

  • The pySuStaIn package provides an accessible implementation of the SuStaIn algorithm.
  • The software enables the identification of distinct disease subtypes and stages from complex patient data.
