FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Fractional Probability Measure and Its Properties [PDF]
Journal of Sciences, Islamic Republic of Iran, 2010 Based on recent studies by Guy Jumarie [1] which defines probability density of fractional order and fractional moments by using fractional calculus (fractional derivatives and fractional integration), this study expands the concept of probability ...

Visit Probability in Space–Time Prisms Based on Binomial Random Walk
ISPRS International Journal of Geo-Information, 2020 Space–time prisms are used to model the uncertainty of space–time locations of moving objects between (for instance, GPS-measured) sample points. However, not all space–time points in a prism are equally likely and we propose a simple, formal model for ...

Geostationary Orbital Debris Collision Hazard after a Collision
Aerospace, 2022 Many space objects are densely distributed in the geostationary (GEO) band, and the long-term impact of the collision of GEO spacecraft and space debris on the GEO environment has attracted more and more attention.

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Representing Probability Measures using Probabilistic Processes [PDF]
, 2006 In the Type-2 Theory of Effectivity, one considers representations of topological spaces in which infinite words are used as "names" for the elements they represent.

The entropy of a mixture of probability distributions
Entropy, 2005 If a message can have n different values and all values are equally probable, then the entropy of the message is log(n). In the present paper, we investigate the expectation value of the entropy, for arbitrary probability distribution.

Copulas in Classical Probability Sense
مجلة بغداد للعلوم, 2020 Copulas are simply equivalent structures to joint distribution functions. Then, we propose modified structures that depend on classical probability space and concepts with respect to copulas.

Mutual information of population codes and distance measures in probability space. [PDF]
Physical Review Letters, 2001 We studied the mutual information between a stimulus and a system consisting of stochastic, statistically independent elements that respond to a stimulus.
