Network analysis of tail-biting in pigs – the impact of missed biting events on centrality parameters

Journal of Agricultural Sciences, 2022
With social network analysis, group structures of animals can be studied. However, underlying behavioural observations face problems of missing events or deviations between observers.

On the Minimum Distance of Generalized Spatially Coupled LDPC Codes [PDF]

, 2013
Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes.

Activity and synchrony patterns obtained by a tracking-by-detection algorithm as potential predictors of tail biting at pen and individual level in pigs

Animal
Tail biting is a major welfare concern in pigs. Timely interventions may help to reduce its spread in an outbreak. However, tail biting is usually detected only at an injury stage. Therefore, early indicators are needed to predict outbreaks.

Changes in tail posture detected by a 3D machine vision system are associated with injury from damaging behaviours and ill health on commercial pig farms.

PLoS ONE, 2021
To establish whether pig tail posture is affected by injuries and ill health, a machine vision system using 3D cameras to measure tail angle was used. Camera data from 1692 pigs in 41 production batches of 42.4 (±16.6) days in length over 17 months at ...

AGGRESSIVE BEHAVIORS AND THEIR EFFECT ON RESOURCE USE BY MALE LITTLE BROWN SKINKS, SCINCELLA LATERALIS [PDF]

, 2017
The aggressive behaviors of adult male Little Brown Skinks, Scincella lateralis, and their effects on access to an important resource (a single retreat) were the subject of a study consisting of 10 laboratory trials in which the behavioral interactions ...

Local Irreducibility of Tail-Biting Trellises [PDF]

IEEE Transactions on Information Theory, 2013
This paper investigates tail-biting trellis realizations for linear block codes. Intrinsic trellis properties are used to characterize irreducibility on given intervals of the time axis. It proves beneficial to always consider the trellis and its dual simultaneously.

Characteristic Generators and Dualization for Tail-Biting Trellises

, 2011
This paper focuses on dualizing tail-biting trellises, particularly KV-trellises. These trellises are based on characteristic generators, as introduced by Koetter/Vardy (2003), and may be regarded as a natural generalization of minimal conventional ...
