On the non-separable theory of k-borel and k-souslin sets
, 1973 The object of the paper is to extend the classical concepts of a Borel and Souslin set for non-separable metric spaces by allowing σ-discrete families of cardinality ⩽ k (k an infinite cardinal) to replace countable families in the standard definitions ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The North Qiangtang Block occupies a pivotal position within the eastern Tethyan realm, and its paleogeographic reconstruction is critical for constraining Tethyan geometry and evolution. However, its Late Paleozoic paleogeography and Paleo‐Tethyan Ocean–continent configuration remain controversial due to limited reliable age‐constrained ...

On the Meaning of Localization in Non‐Local Quantum Field Theory
Annalen der Physik, Volume 538, Issue 6, June 2026.In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

Convex functions with non-Borel set of Gâteaux differentiability points [PDF]
, 1998 summary:We show that on every nonseparable Banach space which has a fundamental system (e.g\. on every nonseparable weakly compactly generated space, in particular on every nonseparable Hilbert space) there is a convex continuous function $f$ such that ...

HPV‐Adjusted Feature Screening With FDR Control in Head and Neck Cancer
Biometrical Journal, Volume 68, Issue 3, June 2026.ABSTRACT Human papillomavirus (HPV) is a well‐established prognostic factor in head and neck (HN) cancer, with HPV‐positive patients exhibiting markedly better survival outcomes compared to their HPV‐negative counterparts. While advances in (cancer) genomics have been pivotal to precision medicine, existing gene screening methods for identifying ...

An Example of a Measurable Set that is not Borel
, 2016 This thesis gives a more detailed version of a proof from Daniel Mauldin that the set of continuous functions defined on the interval $[0,1]$ that are nowhere differentiable is not Borel.

Non‐negative Gaussian estimation of variance components in random effects models
Canadian Journal of Statistics, Volume 54, Issue 2, June 2026.Abstract When used to estimate variance components (VCs), confidence intervals (CIs) can be truncated at zero, have a point estimate not in the quoted CI, be empty with positive probability, or be all‐inclusive. This is because they have conflicting dual roles, since they are considered to cover the parameter with a specified probability while also ...

Topologies on the group of Borel automorphisms of a standard Borel space
, 2006 The paper is devoted to the study of topologies on the group $\text{\rm Aut}(X,{\Cal B})$ of all Borel automorphisms of a standard Borel space $(X, {\mathcal B})$. Several topologies are introduced and all possible relations between them are found.

International Journal of Robust and Nonlinear Control, Volume 36, Issue 9, Page 4957-4970, June 2026.ABSTRACT Data‐based learning of system dynamics allows model‐based control approaches to be applied to systems with partially unknown dynamics. Gaussian process regression is a preferred approach that outputs not only the learned system model but also the variance of the model, which can be seen as a measure of uncertainty.
