InstaMap: instant‐NGP for cryo‐EM density maps

Acta Crystallographica Section D, Volume 81, Issue 4, Page 147-169, April 2025.
Cryo‐EM density‐map inference, with fixed pose and contrast transfer function, using a multi‐resolution hash‐encoding framework called instant‐NGP, is described, together with its extension to heterogeneity inference by bending space with a per‐image vector field.Despite the parallels between problems in computer vision and cryo‐electron microscopy ...

Machine Learning in Polymer Research

Advanced Materials, Volume 37, Issue 11, March 19, 2025.
Artificial intelligence (AI) has permeated every aspect of science, including polymer research. Researchers from both fields need to collaborate to understand the challenges and opportunities of each domain. This review is therefore written by mathematicians and polymer chemists to highlight the key research questions polymer chemists aim to address ...

Additive Manufacturing of Organic Electrochemical Transistors: Methods, Device Architectures, and Emerging Applications

Small, Volume 21, Issue 11, March 19, 2025.
Organic electrochemical transistors (OECTs) are essential for bioelectronics, neuromorphics, and flexible electronics. This review examines additive manufacturing advances for OECTs, covering printing techniques, device architectures, and applications including biochemical sensing, neuromorphic, green bio‐electronics, self‐healable, and 4D electronics.

The rank of sparse symmetric matrices over arbitrary fields

Random Structures &Algorithms, Volume 66, Issue 1, January 2025.
Abstract Let 𝔽 be an arbitrary field and (Gn,d/n)n$$ {\left({\boldsymbol{G}}_{n,d/n}\right)}_n $$ be a sequence of sparse weighted Erdős–Rényi random graphs on n$$ n $$ vertices with edge probability d/n$$ d/n $$, where weights from 𝔽∖{0} are assigned to the edges according to a matrix Jn$$ {J}_n $$.

Chow rings of matroids as permutation representations

Journal of the London Mathematical Society, Volume 111, Issue 1, January 2025.
Abstract Given a matroid with a symmetry group, we study the induced group action on the Chow ring of the matroid with respect to symmetric building sets. This turns out to always be a permutation action. Work of Adiprasito, Huh and Katz showed that the Chow ring satisfies Poincaré duality and the Hard Lefschetz theorem.

Pure Event Semantics

Philosophical Perspectives, Volume 38, Issue 1, Page 54-88, December 2024.
ABSTRACT In a pure event semantics for natural language, the domain of quantification and predication is limited to events and states. I offer pure event semantic analyses of several phenomena, some of which have not been treated before in formal semantics. In the pure event semantics sketched in the second section, nouns are state predicates, and this

Harder–Narasimhan filtrations of persistence modules

Transactions of the London Mathematical Society, Volume 11, Issue 1, December 2024.
Abstract The Harder–Narasimhan (HN) type of a quiver representation is a discrete invariant parameterised by a real‐valued function (called a central charge) defined on the vertices of the quiver. In this paper, we investigate the strength and limitations of HN types for several families of quiver representations which arise in the study of persistence

Isometries of Lipschitz‐free Banach spaces

Journal of the London Mathematical Society, Volume 110, Issue 5, November 2024.
Abstract We describe surjective linear isometries and linear isometry groups of a large class of Lipschitz‐free spaces that includes, for example, Lipschitz‐free spaces over any graph. We define the notion of a Lipschitz‐free rigid metric space whose Lipschitz‐free space only admits surjective linear isometries coming from surjective dilations (i.e ...

Achievement goal theory in STEM education: A systematic review

Journal of Engineering Education, Volume 113, Issue 4, Page 986-1007, October 2024.
Abstract Background Achievement goal theory is a popular motivational theory within education and psychology, with several review papers summarizing the extensive work done in these fields. Although reviews exist in these specific fields, none exists within science, technology, engineering, and mathematics (STEM) education.
