Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

open access: yesAnimal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

Objective-prism and slit-spectra redshifts in a study of the distribution of galaxies [PDF]

open access: yes, 2014
A thorough and detailed investigation into the accuracy, reliability and consistency of the objective-prism redshift technique with changes in plate material, measuring machine and reduction techniques has been undertaken.

Counter-Rotating Disks in Galaxies

open access: yes, 2023
reservedCounter-rotation is a phenomenon found in some galaxies; it happens when a counter-rotating disk which rotates in an opposite direction to the main disk is found.

Longitudinal and cross‐sectional perspectives on elementary school children's post‐error slowing in reading and arithmetic

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Background This study investigated the development of primary school children's error‐related adjustments in reading and arithmetic, both cross‐sectionally and longitudinally. Aims We aimed to uncover monitoring‐based cognitive control processes and often‐overlooked strategy use in academic tasks requiring a balancing of speed and accuracy ...

Groups, clusters and superclusters of galaxies [PDF]

open access: yes, 1991
Galaxies are observed in a diverse range of associations. Understanding the dynamical, statistical and clustering properties of aggregations of galaxies forms the main body of this thesis.

The nature of early-type galaxies in hierarchical models [PDF]

open access: yes, 2008
In this Thesis we describe the properties of early-type galaxies in the context of hierarchical galaxy formation. We use two variants of the GALFORM model originally introduced by Cole et al.: the Baugh et al. and the Bower et al. models.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

open access: yesComputer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

The clustering and number counts of galaxies [PDF]

open access: yes, 2001
We present a Curtis Schmidt CCD survey of two strips of the sky overlapping with the NGC and SGC 2dFGRS fields. When this survey is used in conjunction with data from the APM Galaxy Survey, DUKST, 2dFGRS and 2MASS, we find that there is a hole in the SGC
