Selection-mutation balance models with epistatic selection [PDF]

, 2008
We present an application of birth-and-death processes on configuration spaces to a generalized mutation4 selection balance model. The model describes the aging of population as a process of accumulation of mu5 tations in a genotype. A rigorous treatment

Thrombectomy for Stroke at 6 to 16 Hours with Selection by Perfusion Imaging

New England Journal of Medicine, 2018
Background Thrombectomy is currently recommended for eligible patients with stroke who are treated within 6 hours after the onset of symptoms. Methods We conducted a multicenter, randomized, open‐label trial, with blinded outcome assessment, of ...

Selecting the Selection

, 2016
Modern saturation-based Automated Theorem Provers typically implement the superposition calculus for reasoning about first-order logic with or without equality. Practical implementations of this calculus use a variety of literal selections and term orderings to tame the growth of the search space and help steer proof search.

Postcopulatory sexual selection [PDF]

, 2002
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to ...

Darwinian Data Structure Selection [PDF]

, 2018
Data structure selection and tuning is laborious but can vastly improve an application's performance and memory footprint. Some data structures share a common interface and enjoy multiple implementations.

Unobservable Selection and Coefficient Stability: Theory and Evidence

, 2019
A common approach to evaluating robustness to omitted variable bias is to observe coefficient movements after inclusion of controls. This is informative only if selection on observables is informative about selection on unobservables.
