Transforming gender relations through applied mathematics? Befunde aus einem mathematischen Exzellenzcluster

open access: yesGender
Die Gleichstellung der Geschlechter in der Mathematik ist nicht annähernd erreicht. Weiterhin bestehende Disparitäten werden unter anderem durch fachkulturelle Spezifika begründet.

Localizable Fluorescent Metal Ion Indicators With Tunable Colors

open access: yesAdvanced Science, EarlyView.
A modular platform enables the generation of fluorescent metal ion indicators with tunable emission colors and precise subcellular localization. Conjugation to self‐labeling proteins yields bright, color‐tunable potassium probes that permit wash‐free live‐cell imaging, revealing dynamic potassium efflux in stimulated neurons.

Data‐Driven Modeling of Composition–Processing–Microstructure Relations for Recycled Aluminum Cast Alloys

open access: yesAdvanced Science, EarlyView.
Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

A runoff system restores the principle of minimum differentiation [PDF]

open access: yes, 1999
We show that the principle of minimum differentiation holds in two-round elections, for any number of candidates, regardless of the presence of entrants, or the distribution of voters’ preferences.
