Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

open access: yesAdvanced Intelligent Discovery, EarlyView.
Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

The Many Uses of Predicates of Taste and the Challenge from Disagreement

open access: yesStudies in Logic, Grammar and Rhetoric, 2016
In the debate between contextualism and relativism about predicates of taste, the challenge from disagreement (the objection that contextualism cannot account for disagreement in ordinary exchanges involving such predicates) has played a central role ...

Toulmin's Model of Argument and the Question of Relativism (J. A. Blair Prize, 2005)

open access: yesInformal Logic, 2004
In The Uses of Argument, Toulmin proposed a distinction between fielddependent and field-invariant standards for argument appraisal that gave rise to a relativistic understanding of his theory.

The Highest Oxidation States of the Rare‐Earth Elements and the Challenge of Praseodymium(+5) Compounds

open access: yesAngewandte Chemie International Edition, EarlyView.
Rare Earth Elements are known to form tri‐ and also di‐valent compounds. A few tetra‐valent compounds are also known, and recently the first molecules and crystals with Praseodymium(+5) were synthesized. By defining the atomic Ionization Quotient IQ, Ln(+4) compounds with suitable ligands appear possible for almost all 4f elements, while Pr(+5) may ...

Anomalous Magnetization Dynamics After Dual Optical Excitation

open access: yesAdvanced Physics Research, EarlyView.
We demonstrate that dual‐pump femtosecond excitation in copper leads to a pronounced, non‐additive change in spin and orbital relaxation dynamics compared to single‐pulse excitation. Time‐resolved magneto‐optical Kerr effect measurements reveal a 2.5× increase in angular momentum decay time, highlighting a new route to ultrafast control of electronic ...
