Bayesian Estimation of Transition Rates in Two‐State Nonhomogeneous Markov Jump Processes With Intermittent Observations: An Honest‐Time Data‐Augmentation Approach

open access: yesScandinavian Journal of Statistics, Volume 53, Issue 3, Page 1343-1357, September 2026.
ABSTRACT A possibly time‐dependent transition intensity matrix or generator (Q(t))$$ \left(Q(t)\right) $$ characterizes the law of a Markov jump process (MP). For a time‐homogeneous MP, the transition probability matrix (TPM) can be expressed as a matrix exponential of Q$$ Q $$.

Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Isotope Effects on H2O, OH, and H Adsorption on Pd(111): Insights From Combined Plane Wave and Localized Basis Set Calculations

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 15, August 5, 2026.
Elucidating hydrogen/deuterium isotope effects on metal surfaces is important for catalyst design and isotope labelling. We study H2O, OH, and H adsorption on Pd(111) using a combined plane wave and localized basis set scheme that incorporates nuclear quantum effects within density functional theory.

The Role of Charge Transfer and Linker States in the Magnetoluminescence of a Diradical With Two Spatially Proximate Triarylmethyl Units

open access: yesAdvanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...
