Splicing Systems from Past to Future: Old and New Challenges
, 2014 A splicing system is a formal model of a recombinant behaviour of sets of double stranded DNA molecules when acted on by restriction enzymes and ligase. In this survey we will concentrate on a specific behaviour of a type of splicing systems, introduced ...

Centrifugation Theory Revisited: Understanding and Modeling the Centrifugation of 2D Nanosheets
Advanced Materials Interfaces, EarlyView.Colloidal dispersions of nanomaterials are often size‐selected by centrifugation, for anisotropic particle shapes in trial and error. This paper describes the derivation of an equation of motion for 2D objects. The model is validated using different nanosheets produced from liquid phase exfoliation and can be used to predict the average nanosheet sizes

Toward a Semiotic Framework for Using Technology in Mathematics Education: The Case of Learning 3D Geometry [PDF]
, 2004 This paper proposes and examines a semiotic framework to inform the use of technology in mathematics education. Semiotics asserts that all cognition is irreducibly triadic, of the nature of a sign, fallible, and thoroughly immersed in a continuing ...

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel
Advanced Materials Technologies, EarlyView.The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Inverse Design in Nanophotonics via Representation Learning
Advanced Optical Materials, EarlyView.This review frames machine learning (ML) in nanophotonics through a classification based on where ML is applied. We categorize methods as either output‐side, which create differentiable surrogates for solving Maxwell's partial differential equations (PDEs), or input‐side, which learn compact representations of device geometry.

Metalens Array for Complex‐Valued Optical Discrete Fourier Transform
Advanced Optical Materials, EarlyView.A single‐layer metalens‐array device performs complex‐to‐complex discrete Fourier transforms (DFTs) optically with O(N) digital time complexity. Integrated interferometric phase retrieval and error mitigation scheme enables accurate, compact, and low‐power optical computing. The approach provides a versatile framework for implementing arbitrary complex‐

Boosting the Performance of Epitaxial Perovskite Microstructures by Surface Passivation
Advanced Optical Materials, EarlyView.Surface passivation is applied to epitaxial perovskite structures. Improvements are obtained in respect to luminescence intensity and decay time, as well in respect to photodetection and lasing. Highlight results include photoluminescence transients that are limited only by carrier diffusion and a record low laser threshold for microcrystal‐based ...
