Numerical Simulation of Helical Jets at Active Region Peripheries (2019)
Journal Article
Wyper, P. F., DeVore, C. R., & Antiochos, S. K. (2019). Numerical Simulation of Helical Jets at Active Region Peripheries. Monthly Notices of the Royal Astronomical Society, 490(3), 3679-3690. https://doi.org/10.1093/mnras/stz2674

Coronal jets are observed above minority polarity intrusions throughout the solar corona. Some of the most energetic occur on the periphery of active regions where the magnetic field is strongly inclined. These jets exhibit a non-radial propagation i...

An sl(n) stable homotopy type for matched diagrams (2019)
Journal Article
Jones, D., Lobb, A., & Schuetz, D. (2019). An sl(n) stable homotopy type for matched diagrams. Advances in Mathematics, 356, Article 106816. https://doi.org/10.1016/j.aim.2019.106816

There exists a simplified Bar-Natan Khovanov complex for open 2-braids. The Khovanov cohomology of a knot diagram made by gluing tangles of this type is therefore often amenable to calculation. We lift this idea to the level of the Lipshitz-Sarkar sta... Read More about An sl(n) stable homotopy type for matched diagrams.

Statistical Characterisation of Fluvial Sand Bodies: Implications for Complex Reservoir Models (2019)
Presentation / Conference Contribution
Franzel, M., Jones, S., Jermyn, I., Allen, M., & McCaffrey, K. (2019, December). Statistical Characterisation of Fluvial Sand Bodies: Implications for Complex Reservoir Models. Presented at Petroleum Geostatistics 2019

The three-dimensional geometry of fluvial channel sand bodies has received considerably less attention than their internal sedimentology, despite the importance of sandstone body geometry for subsurface reservoir modelling. The aspect ratio (width/th... Read More about Statistical Characterisation of Fluvial Sand Bodies: Implications for Complex Reservoir Models.

Colliding Pomerons (2019)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2019). Colliding Pomerons. Journal of Physics G: Nuclear and Particle Physics, 46(11), Article 11LT01. https://doi.org/10.1088/1361-6471/ab3a88

We recall the main properties of inclusive particle distributions expected for Pomeron-proton and Pomeron–Pomeron interactions. Due to the small size of the Pomeron we expect larger transverse momenta of secondaries and a smaller probability of multi... Read More about Colliding Pomerons.

Convergence of Brownian motions on metric measure spaces under Riemannian Curvature–Dimension conditions (2019)
Journal Article
Suzuki, K. (2019). Convergence of Brownian motions on metric measure spaces under Riemannian Curvature–Dimension conditions. Electronic Journal of Probability, 24, Article 102. https://doi.org/10.1214/19-ejp346

We show that the pointed measured Gromov convergence of the underlying spaces implies (or under some condition, is equivalent to) the weak convergence of Brownian motions under Riemannian Curvature-Dimension conditions.

Quantile-Based Estimation of the Finite Cauchy Mixture Model (2019)
Journal Article
Kalantan, Z. I., & Einbeck, J. (2019). Quantile-Based Estimation of the Finite Cauchy Mixture Model. Symmetry, 11(9), Article 1186. https://doi.org/10.3390/sym11091186

Heterogeneity and outliers are two aspects which add considerable complexity to the analysis of data. The Cauchy mixture model is an attractive device to deal with both issues simultaneously. This paper develops an Expectation-Maximization-type algor... Read More about Quantile-Based Estimation of the Finite Cauchy Mixture Model.

A family of freely slice good boundary links (2019)
Journal Article
Cha, J. C., Kim, M. H., & Powell, M. (2020). A family of freely slice good boundary links. Mathematische Annalen, 376(3-4), 1009-1030. https://doi.org/10.1007/s00208-019-01907-3

We show that every good boundary link with a pair of derivative links on a Seifert surface satisfying a homotopically trivial plus assumption is freely slice. This subsumes all previously known methods for freely slicing good boundary links with two... Read More about A family of freely slice good boundary links.

Complexity and typical microstates (2019)
Journal Article
Ross, S. F. (2019). Complexity and typical microstates. Physical Review D, 100(6), Article 066014. https://doi.org/10.1103/physrevd.100.066014

Typical black hole microstates in AdS=CFT were recently conjectured to have a geometrical dual with a smooth horizon and a portion of a second asymptotic region. I consider the application of the holographic complexity conjectures to this geometry. T... Read More about Complexity and typical microstates.

Variations of power-expected-posterior priors in normal regression models (2019)
Journal Article
Fouskakis, D., Ntzoufras, I., & Perrakis, K. (2020). Variations of power-expected-posterior priors in normal regression models. Computational Statistics & Data Analysis, 143, Article 106836. https://doi.org/10.1016/j.csda.2019.106836

The power-expected-posterior (PEP) prior is an objective prior for Gaussian linear models, which leads to consistent model selection inference, under the M-closed scenario, and tends to favour parsimonious models. Recently, two new forms of the PEP p... Read More about Variations of power-expected-posterior priors in normal regression models.
