A Theory of Protocol Composition [article]

Laura Bocchi, Dominic Orchard, Laura Voinea
2022 arXiv   pre-print
The resulting approach gives a theoretical basis for protocol (re-)engineering based on a process calculus with constraint annotations.  ...  Composition is considered for implementations of a protocol, but not for the protocols themselves as engineering components.  ...  A {Si} Ai A {+{li : Si}i∈I } i∈I Ai [bra] A ∪ {n} {S} AA {assert(n).S} A ′ [assert] A ∪ {n} {S} AA ∪ {n} {require(n).S} A ′ [require] A \ {n} {S} A ′ n ∈ A A {consume(n).S} A ′ [consume] A {S} A  ...

Seasonal patterns of habitat use by insectivorous bats in a subtropical African agro-ecosystem dominated by macadamia orchards

Peter John Taylor, Ara Monadjem, Jacobus Nicolaas Steyn
2013 African Journal of Ecology  
We report on acoustic surveys of insectivorous bats conducted during seven months of the year using ANABAT recordings in two habitats (macadamia orchards and adjacent riparian bush) in a subtropical agroecosystem  ...  We postulate that the significant pattern of seasonality of commuting and/or foraging activity of bats in macadamia orchards (which is more marked in open-air foragers) may be driven by the seasonal abundance  ...  Acknowledgements The study was funded by a Niche-Area Grant of the University of Venda as well as a National Research Foundation (NRF) Grant for Incentive Funding of Rated Researchers.  ...

A Notation for Comonads [chapter]

Dominic Orchard, Alan Mycroft
2013 Lecture Notes in Computer Science  
The category-theoretic concept of a monad occurs widely as a design pattern for functional programming with effects.  ...  Via our notation, we also provide a tutorial on programming with comonads.  ...  For example, a comonad of labelled binary trees can be defined: data BTree a = Leaf a | Node a (BTree a) (BTree a) instance Comonad BTree where extract (Leaf a) = a extract (Node a l r ) = a extend f (  ...

Discrimination Contours for Moving Sounds Reveal Duration and Distance Cues Dominate Auditory Speed Perception

Tom C. A. Freeman, Johahn Leung, Ella Wufong, Emily Orchard-Mills, Simon Carlile, David Alais, Christian Friedrich Altmann
2014 PLoS ONE  
The orientation of the contour (typically elliptical in shape) reveals which cue or combination of cues dominates.  ...  The technique produces a set of motion discrimination thresholds that define a contour in the distance-duration plane for different combination of the three cues, based on a 3-interval oddity task.  ...  We found good evidence that duration and to a lesser extent distance dominated the speed cue at threshold.  ...

The frequency of pathogenic variants was less than reported among the younger UK Biobank population, suggesting these variants confer a survival disadvantage during the middle years of life.  ...  We compared the prevalence of pathogenic variants in medically actionable autosomal dominant disease genes with that from the UK Biobank population, and assessed their clinical impact using personal medical  ...  Adult-onset conditions, by contrast, tend to be autosomal dominant, with only a single 157 pathogenic variant required to infer risk or predisposition to disease.  ...

How to Take the Inverse of a Type

In this pearl, we show that regular types in a linear setting permit a useful notion of multiplicative inverse, allowing us to "divide" one type by another.  ...  In functional programming, regular types are a subset of algebraic data types formed from products and sums with their respective units.  ...  Orchard 5:11 where − 1 and − 2 correspond to the two successive components of the 2-hole.  ...
