Colourings of Uniform Group Divisible Designs and Maximum Packings

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A weak c $c$‐colouring of a design is an assignment of colours to its points from a set of c $c$ available colours, such that there are no monochromatic blocks. A colouring of a design is block‐equitable, if for each block, the number of points coloured with any available pair of colours differ by at most one.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Reaction Rate Coefficients and Adduct Formation in the Cl Atom + (E)‐CF3CF2CH=CHCF2CF3 Reaction

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT In this work, rate coefficients for the Cl‐atom + (E)‐CF3CF2CH═CHCF2CF3 (HFO‐153‐10mczz, F22E) gas‐phase reaction were measured as a function of temperature and pressure, k(243–323 K, 50–300 Torr), using a pulsed laser photolysis‐resonance fluorescence (PLP‐RF) technique.

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations
