Extinction time distributions of populations and genotypes
David Kessler, Nadav M. Shnerb
In the long run, the eventual extinction of any biological population is an inevitable outcome. While extensive research has focused on the average time it takes for a population t…
Neutral dynamics with environmental noise: age-size statistics and species lifetimes
David Kessler, Samir Suweis, Marco Formentin +1
Neutral dynamics, where taxa are assumed to be demographically equivalent and their abundance is governed solely by the stochasticity of the underlying birth-death process, has pro…
Uncertainty relation between detection probability and energy fluctuations
Felix Thiel, Itay Mualem, David Kessler +1
A classical random walker starting on a node of a finite graph will always reach any other node since the search is ergodic, namely it is fully exploring space, hence the arrival p…
Distributions of Triplets in Genetic Sequences
Yu Shi, Ido Kanter, David Kessler
Distributions of triplets in some genetic sequences are examined and found to be well described by a 2-parameter Markov process with a sparse transition matrix. The variances of al…
Two State Behavior in a Solvable Model of -hairpin folding
Chinlin Guo, Herbert Levine, David Kessler
Understanding the mechanism of protein secondary structure formation is an essential part of protein-folding puzzle. Here we describe a simple model for the formation of the -h…
AcuityBench: Evaluating Clinical Acuity Identification and Uncertainty Alignment
Robin Linzmayer, Georgianna Lin, Di Coneybeare +22
We introduce AcuityBench, a benchmark for evaluating whether language models identify the appropriate urgency of care from user medical presentations. Existing health benchmarks em…
