On the elementary symmetric functions of a sum of matrices
, 2009 Often in mathematics it is useful to summarize a multivariate phenomenon with a single number and in fact, the determinant -- which is represented by det -- is one of the simplest cases.

Advanced Functional Materials, EarlyView.In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications
Advanced Functional Materials, EarlyView.Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Potentials in Udeskole: Inquiry-Based Teaching Outside the Classroom
Frontiers in Education, 2018 Most research on outdoor education, including the Scandinavian concept udeskole (regular curriculum-based teaching outside the classroom), has focused on pupils' outcomes, whereas less has focused on teachers' practices. In this article, we described the

The search for non-symmetric ribbon knots
, 2019 We present the results of Axel Seeliger's tabulation of symmetric union presentations for ribbon knots with crossing numbers 11 and 12 and exhibit possible examples for ribbon knots which are not representable as symmetric unions.

The role of sign in students' modeling of scalar equations
, 2009 We describe students revising the mathematical form of physics equations to match the physical situation they are describing, even though their revision violates physical laws.

Advanced Healthcare Materials, EarlyView.Nonclinical evaluation of biological responses to implanted medical devices and combination products in animals is required to predict possible outcomes and risks in patients. This paper describes globally accepted pathology “best practices” that 1) effectively address ISO standards and current regulatory guidance for medical device development and 2 ...
