Lack of effect of a parent‐delivered early language intervention: Evidence from a randomised controlled trial completed during COVID‐19 (2024)
Journal Article
Burgoyne, K., Hargreaves, S., Akhter, N., Cramman, H., Eerola, P., Einbeck, J., & Menzies, V. (online). Lack of effect of a parent‐delivered early language intervention: Evidence from a randomised controlled trial completed during COVID‐19. JCPP Advances, Article e12279. https://doi.org/10.1002/jcv2.12279

Background: Parents play a key role in their child's early development but evidence that parental engagement strategies are effective is unclear. The current study evaluated a parent‐delivered early language teaching programme that aimed to support c...

Undulatory swimming in suspensions and networks of flexible filaments (2024)
Journal Article
Townsend, A., & Keaveny, E. (2024). Undulatory swimming in suspensions and networks of flexible filaments. Journal of Fluid Mechanics, 993, Article A10. https://doi.org/10.1017/jfm.2024.603

Many biological fluids are composed of suspended polymers immersed in a viscous fluid. A prime example is mucus, where the polymers are also known to form a network. While the presence of this microstructure is linked with an overall non-Newtonian re... Read More about Undulatory swimming in suspensions and networks of flexible filaments.

Ethical considerations of use of hold-out sets in clinical prediction model management (2024)
Journal Article
Chislett, L., Aslett, L. J. M., Davies, A. R., Vallejos, C. A., & Liley, J. (online). Ethical considerations of use of hold-out sets in clinical prediction model management. AI and Ethics, https://doi.org/10.1007/s43681-024-00561-z

Clinical prediction models are statistical or machine learning models used to quantify the risk of a certain health outcome using patient data. These can then inform potential interventions on patients, causing an effect called performative predictio...

Photospheric signatures of CME onset (2024)
Journal Article
Aslam, O. P. M., MacTaggart, D., Williams, T., Fletcher, L., & Romano, P. (2024). Photospheric signatures of CME onset. Monthly Notices of the Royal Astronomical Society, 534(1), 444-454. https://doi.org/10.1093/mnras/stae2110

Coronal mass ejections (CMEs) are solar eruptions that involve large-scale changes to the magnetic topology of an active region. There exists a range of models for CME onset which are based on twisted or sheared magnetic field above a polarity invers... Read More about Photospheric signatures of CME onset.

Nitrogen isotope variability of macroalgae from a small fishing village, Staithes Harbour, Yorkshire, UK. (2024)
Journal Article
Alldred, F. C., Gröcke, D. R., & Jackson, S. E. (2024). Nitrogen isotope variability of macroalgae from a small fishing village, Staithes Harbour, Yorkshire, UK. Marine Pollution Bulletin, 207, Article 116828. https://doi.org/10.1016/j.marpolbul.2024.116828

Macroalgal nitrogen isotope analysis (δ N) is a reliable method for the identification of nitrogen pollutant sources. Understanding δ N geospatial variation within small bays and/or harbour environments can help identify point sources of nitrogen pol...

Positive Reinforced Generalized Time-Dependent Pólya Urns via Stochastic Approximation (2024)
Journal Article
Ruszel, W. M., & Thacker, D. (2024). Positive Reinforced Generalized Time-Dependent Pólya Urns via Stochastic Approximation. Journal of Theoretical Probability, 37(4), 2859-2885. https://doi.org/10.1007/s10959-024-01366-w

Consider a generalized time-dependent Pólya urn process defined as follows. Let d ∈ N be the number of urns/colors. At each time n, we distribute σn balls randomly to the d urns, proportionally to f , where f is a valid reinforcement function. We con...

Metric geometry of spaces of persistence diagrams (2024)
Journal Article
Che, M., Galaz Garcia, F., Guijarro, L., & Membrillo Solis, I. (2024). Metric geometry of spaces of persistence diagrams. Journal of Applied and Computational Topology, 8(8), 2197-2246. https://doi.org/10.1007/s41468-024-00189-2

Persistence diagrams are objects that play a central role in topological data analysis. In the present article, we investigate the local and global geometric properties of spaces of persistence diagrams. In order to do this, we construct a family of...

Wasserstein geometry and Ricci curvature bounds for Poisson spaces (2024)
Journal Article
Dello Schiavo, L., Herry, R., & Suzuki, K. (2024). Wasserstein geometry and Ricci curvature bounds for Poisson spaces. Journal de l’École polytechnique — Mathématiques, 11, 957-1010. https://doi.org/10.5802/jep.270

We study the geometry of Poisson point processes from the point of view of optimal transport and Ricci lower bounds. We construct a Riemannian structure on the space of point processes and the associated distance W that corresponds to the Benamou–Bre...

Rationality of twist representation zeta functions of compact p-adic analytic groups (2024)
Journal Article
Stasinski, A., & Zordan, M. (2024). Rationality of twist representation zeta functions of compact p-adic analytic groups. Transactions of the American Mathematical Society, 377, 7601-7631

We prove that for any twist rigid compact p-adic analytic group G, its twist representation zeta function is a finite sum of terms n −s i f i (p −s), where n i are natural numbers and f i (t) ∈ Q(t) are rational functions. Mero-morphic continuation a... Read More about Rationality of twist representation zeta functions of compact p-adic analytic groups.
