Discovery of long‐distance gamete dispersal in a lichen‐forming ascomycete

open access: yesNew Phytologist, 2017
Summary Accurate estimates of gamete and offspring dispersal range are required for the understanding and prediction of spatial population dynamics and species persistence.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

The p-Dispersion Problem with Distance Constraints.

open access: yes, 2023
In the (maxmin) p-dispersion problem we seek to locate a set of facilities in an area so that the minimum distance between any pair of facilities is maximized. We study a variant of this problem where there exist constraints specifying the minimum allowed distances between the facilities.

The constant philopater hypothesis : a new life history invariant for dispersal evolution [PDF]

open access: yes, 2015
This research was supported by Wolfson College Cambridge (A.M.M.R.) and the Natural Environment Research Council (grant no. NE/K009524/1) (A.G.).Surprising invariance relationships have emerged from the study of social interaction, whereby a cancelling ...

Supporting data for "Direct tracking of pollen with quantum dots reveals surprising uniformity in dispersal distance across eleven populations of an annual plant"

open access: yes, 2022
Pollen movement is a crucial component of dispersal in seed plants. We used quantum dot pollen labeling, a new technique that overcomes past limitations, to evaluate the spatial scale of pollen dispersal and its relationship with conspecific density ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Optimality of the distance dispersion fixation identification algorithm [PDF]

open access: yesProceedings of the Ninth Biennial ACM Symposium on Eye Tracking Research & Applications, 2016
Researchers use fixation identification algorithms to parse eye movement trajectories into a series of fixations and saccades, simplifying analyses and providing measures which may relate to cognition. The Distance Dispersion (I-DD) a widely-used elementary fixation identification algorithm.

How Important Is Informed Natal Dispersal for Modelling the Demographic and Genetic Effects of Environmental Variability?

open access: yesEcology and Evolution
Dispersal is a fundamental ecological process that influences population dynamics and genetic diversity and is therefore an important component of the models used to simulate population responses to environmental change.

Life path analysis: scaling indicates priming effects of social and habitat factors on dispersal distances [PDF]

open access: yes, 2001
1. Movements of many animals along a life-path can be separated into repetitive ones within home ranges and transitions between home ranges. We sought relationships of social and environmental factors with initiation and distance of transition movements

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
