Intrinsic Ferromagnetism and Surface Oxidation in Nb2FeC: Revealed by Synchrotron‐Based X‐Ray Spectro‐ and Microscopy

open access: yesAdvanced Electronic Materials, Volume 12, Issue 17, 7 September 2026.
A‐site substitution in Nb2AlC with Fe yields Nb2FeC, a near room‐temperature ferromagnetic MAX phase. Synchrotron‐based spectroscopy and scanning transmission X‐ray microscopy (STXM) with X‐ray magnetic circular dichroism reveal intrinsic bulk ferromagnetism confined to Fe layers, with weak interlayer coupling across Nb2C layer.

Charge and Spin Distribution in the Triplet State of a Porphyrin Cofacial Heterodimer via Hyperfine Spectroscopy

open access: yesChemPhotoChem, Volume 10, Issue 9, September 2026.
The delocalization and charge transfer contributions to the lowest photoexcited triplet state of an Al(III) porphyrin‐P(V) porphyrin cofacial heterodimer (AlPor‐O‐PPor·PF6) have been estimated by means of pulse electron nuclear double resonance spectroscopy in three glass‐forming solvents of different polarity and Lewis basicity.

Bayesian Inference for the Automultinomial Model With an Application to Landcover Data

open access: yesEnvironmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT Multicategory lattice data arise in a wide variety of disciplines such as image analysis, biology, and forestry. We consider modeling such data with the automultinomial model, which can be viewed as a natural extension of the autologistic model to multicategory responses, or equivalently as an extension of the Potts model that incorporates ...

Approximate Reachability for Feedback Linearizable Systems

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 5, Page 1062-1082, September/October 2026.
The backwards reachable set for a dynamical system is the set of states for which there exists a constraint admissible trajectory that reaches a given terminal set. Conventional grid‐based approaches for computing these sets are intractable for many applications.

Compile‐Once Block Encodings for Masked Similarity‐Transformed Effective Hamiltonians

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Composer transforms structured electronic‐structure operators into a reusable quantum‐circuit fabric. Once compiled, the same block‐encoding architecture is re‐dialed through coefficients, rotation angles, and masks to generate similarity‐transformed effective Hamiltonians across related problem instances, avoiding repeated structural recompilation ...
