Journal Article
Alatawi, M., & Zhang, K. (2020). Hausdorff Stability and Error Estimates for Compensated Convexity Based Methods for Approximation and Interpolation for Functions in Rn. Journal of Convex Analysis, 27(4),

We establish error estimates and Hausdorff stability for approximations and interpolations for sampled functions in Rn by using compensated convex transforms introduced previously by K. Zhang [Compensated convexity and its applications, Ann. l’Instit...

Incorporating age and delay into models for biophysical systems (2020)
Journal Article
KhudaBukhsh, W. R., Kang, H.-W., Kenah, E., & Rempała, G. A. (2021). Incorporating age and delay into models for biophysical systems. Physical Biology, 18(1), Article 015002. https://doi.org/10.1088/1478-3975/abc2ab

In many biological systems, chemical reactions or changes in a physical state are assumed to occur instantaneously. For describing the dynamics of those systems, Markov models that require exponentially distributed inter-event times have been used wi...

Predator size affects the intensity of mutual interference in a predatory mirid (2020)
Journal Article
Papanikolaou, N. E., Dervisoglou, S., Fantinou, A., Kypraios, T., Giakoumaki, V., & Perdikis, D. (2020). Predator size affects the intensity of mutual interference in a predatory mirid. Ecology and Evolution, 11(3), 1342-1351. https://doi.org/10.1002/ece3.7137

1. Interference competition occurs when access to an available resource is negatively affected by interactions with other individuals, where mutual interference involves individuals of the same species. The interactive phenomena among individuals may... Read More about Predator size affects the intensity of mutual interference in a predatory mirid.

ISOTROPIC MOTIVES (2020)
Journal Article
Vishik, A. (2020). ISOTROPIC MOTIVES. Journal of the Institute of Mathematics of Jussieu, 21(4), 1271-1330. https://doi.org/10.1017/S1474748020000560

In this article we introduce the local versions of the Voevodsky category of motives with Fp coefficients over a field k, parameterized by finitely-generated extensions of k. We introduce the, so-called, flexible fields, passage to which is conservat... Read More about ISOTROPIC MOTIVES.

Adaptive regularisation for ensemble Kalman inversion (2020)
Journal Article
Iglesias, M. A., & Yang, Y. (2021). Adaptive regularisation for ensemble Kalman inversion. Inverse Problems, 37(2), Article 025008. https://doi.org/10.1088/1361-6420/abd29b

We propose a new regularisation strategy for the classical ensemble Kalman inversion (EKI) framework. The strategy consists of: (i) an adaptive choice for the regularisation parameter in the update formula in EKI, and (ii) criteria for the early stop...

On the monoidal center of Deligne's category Re̲p(St) (2020)
Journal Article

We explicitly compute a monoidal subcategory of the monoidal center of Deligne’s interpolation category Rep(St), for t not necessarily a natural number, and we show that this subcategory is a ribbon category. For t = n, a natural number, there exists... Read More about On the monoidal center of Deligne's category Re̲p(St).

A ray dynamics describing wave transport on curved and smooth thin shells can be obtained from the underlying wave equations via the Eikonal approximation. We analyse mid-frequency effects near the ring frequency for curved plates consisting of a cyl... Read More about Tunnelling around bends—Wave scattering in curved shell structures.
