Similar patterns of genetic diversity and linkage disequilibrium in Western chimpanzees (Pan troglodytes verus) and humans indicate highly conserved mechanisms of MHC molecular evolution

open access: yesBMC Evolutionary Biology, 2020
Background Many species are threatened with extinction as their population sizes decrease with changing environments or face novel pathogenic threats.

Relational Concurrent Refinement Part III: Traces, partial relations and automata [PDF]

open access: yes, 2014
Data refinement in a state-based language such as Z is defined using a relational model in terms of the behaviour of abstract programs. Downward and upward simulation conditions form a sound and jointly complete methodology to verify relational data ...

Refinement of Intentions [PDF]

open access: yes, 2016
According to Bratman, future-directed intentions are high-level plans. We view such plans as high-level actions that can typically not be executed directly: they have to be progressively refined until executable basic actions are obtained. Higher- and lower-level actions are linked by the means-end relation, alias instrumentality relation.

A Branch-and-Bound Algorithm for Polymatrix Games ϵ-Proper Nash Equilibria Computation

open access: yesAlgorithms, 2021
When several Nash equilibria exist in the game, decision-makers need to refine their choices based on some refinement concepts. To this aim, the notion of a ϵ-proper equilibria set for polymatrix games is used to develop 0–1 mixed linear programs and ...

Grain refinement efficiency of a new oxide-containing master alloy for aluminium casting alloys [PDF]

open access: yes, 2014
In this study, grain refinement efficiency of a new oxide master alloy based on MgAl2O4 was demonstrated on an A357 alloy. The grain size of the reference alloy was reduced by 50-60% with the addition of the master alloy and introduction of ultrasonic ...

Chemical vapor deposition of poly-p-xylylene in narrow tubes

open access: yesAIP Advances, 2017
Depositing a film via chemical vapor deposition results in superior conformity compared with other deposition techniques, primarily due to the unique chemical interactions between the surface and the reactive compounds.

Abstraction Refinement Guided by a Learnt Probabilistic Model [PDF]

open access: yes, 2015
The core challenge in designing an effective static program analysis is to find a good program abstraction -- one that retains only details relevant to a given query. In this paper, we present a new approach for automatically finding such an abstraction.

Decreased levels of discomfort in repeatedly handled mice during experimental procedures, assessed by facial expressions

open access: yesFrontiers in Behavioral Neuroscience, 2023
Mice are the most commonly used laboratory animal, yet there are limited studies which investigate the effects of repeated handling on their welfare and scientific outcomes.
