Strong Law of Large Numbers of Pettis-Integrable Multifunctions

Journal of Mathematics, 2019
Using reversed martingale techniques, we prove the strong law of large numbres for independent Pettis-integrable multifunctions with convex weakly compact values in a Banach space.

Multicomponent incompressible fluids—An asymptotic study

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 103, Issue 7, July 2023., 2023
Abstract This paper investigates the asymptotic behavior of the Helmholtz free energy of mixtures at small compressibility. We start from a general representation for the local free energy that is valid in stable subregions of the phase diagram. On the basis of this representation we classify the admissible data to construct a thermodynamically ...

The role of cell size in shaping responses to oxygen and temperature in fruit flies

Functional Ecology, Volume 37, Issue 5, Page 1269-1279, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract The body size of an animal is strongly coupled to key ecological traits such as fecundity, mortality and growth. Ectothermic animals mature at smaller body sizes in warmer conditions and under low oxygen availability (hypoxia).

Warming undermines emergence success in a threatened alpine stonefly: A multi‐trait perspective on vulnerability to climate change

Functional Ecology, Volume 37, Issue 4, Page 1033-1043, April 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Vulnerability to warming is often assessed using short‐term metrics such as the critical thermal maximum (CTMAX), which represents an organism's ability to survive extreme heat. However, the long‐term effects of sub‐lethal warming are an essential link to fitness in the

On the cross‐validation bias due to unsupervised preprocessing

Journal of the Royal Statistical Society: Series B (Statistical Methodology), Volume 84, Issue 4, Page 1474-1502, September 2022., 2022
Abstract Cross‐validation is the de facto standard for predictive model evaluation and selection. In proper use, it provides an unbiased estimate of a model's predictive performance. However, data sets often undergo various forms of data‐dependent preprocessing, such as mean‐centring, rescaling, dimensionality reduction and outlier removal. It is often

Functional traits and foraging behaviour: Avian vampire fly larvae change the beak and fitness of their Darwin's finch hosts

Functional Ecology, Volume 36, Issue 7, Page 1806-1817, July 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The avian beak is a key morphological trait used for foraging. If parasites alter beak shape, we may expect changes in host foraging behaviour. Larvae of the avian vampire fly Philornis downsi cause naris enlargement in Darwin's finch nestlings when first and second ...

Human‐mediated eco‐evolutionary processes of the herbivorous insect Hyalopterus arundiniformis during the Holocene

Diversity and Distributions, Volume 28, Issue 6, Page 1313-1326, June 2022., 2022
Abstract Aim Pleistocene climatic fluctuations have been identified as a dominant factor in evolutionary and ecological processes underlying contemporary species distribution. In contrast, anthropogenic activity during the Holocene has been largely neglected in phylogeographic inference.

Uniform Convexity and Convergence of a Sequence of Sets in a Complete Geodesic Space

Abstract and Applied Analysis, Volume 2022, Issue 1, 2022., 2022
In this paper, we first introduce two new notions of uniform convexity on a geodesic space, and we prove their properties. Moreover, we reintroduce a concept of the set‐convergence in complete geodesic spaces, and we prove a relation between the metric projections and the convergence of a sequence of sets.

Graph‐like spaces approximated by discrete graphs and applications

Mathematische Nachrichten, Volume 294, Issue 11, Page 2237-2278, November 2021., 2021
Abstract We define a distance between energy forms on a graph‐like metric measure space and on a suitable discrete weighted graph using the concept of quasi‐unitary equivalence. We apply this result to metric graphs, graph‐like manifolds (e.g. a small neighbourhood of an embedded metric graph) or pcf self‐similar fractals as metric measure spaces with ...

On Mosco convergence of convex sets [PDF]

Bulletin of the Australian Mathematical Society, 1988
We present a natural topology compatible with the Mosco convergence of sequences of closed convex sets in a reflexive space, and characterise the topology in terms of the continuity of the distance between convex sets and fixed weakly compact ones. When the space is separable, the topology is Polish.
