Quillen's Theorem A and the Whitehead theorem for bicategories [PDF]
Chapter 7 of "2-Dimensional Categories" (Oxford University Press,
2021), 2019 We prove a bicategorical analogue of Quillen's Theorem A. As an application, we deduce the well-known result that a pseudofunctor is a biequivalence if and only if it is essentially surjective on objects, essentially full on 1-cells, and fully faithful on 2-cells.

Preference index supported by motivation tests in Nile tilapia
PLOS ONE, 2017 The identification of animal preferences is assumed to provide better rearing environments for the animals in question. Preference tests focus on the frequency of approaches or the time an animal spends in proximity to each item of the investigated resource during a multiple-choice trial.

On the Nile Problem by Sir Ronald Fisher [PDF]
arXiv, 2013 The Nile problem by Ronald Fisher may be interpreted as the problem of making statistical inference for a special curved exponential family when the minimal sufficient statistic is incomplete. The problem itself and its versions for general curved exponential families pose a mathematical-statistical challenge: studying the subalgebras of ancillary ...

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.ABSTRACT Inland recirculating aquaculture is a thriving food industry providing sustainable and locally sourced high‐quality protein. However, its expansion is accompanied by emerging challenges regarding the spread of pathogens and diseases. Detection and management of pathogens in aquaculture remain underdeveloped compared to other animal farming ...
