Engineering Reports, Volume 7, Issue 10, October 2025.Microhardness reached a maximum of 158.5 ± 3.9 HV at 4 wt.% Fe, with tensile strength peaking at 331.9 ± 9.9 MPa, whereas higher Fe addition (6 wt.%) caused microhardness and tensile strength to decline to 142.4 ± 4.8 HV and 294.7 ± 9.2 MPa, respectively, due to particle clustering and thermal softening.

On Endomorphism Universality of Sparse Graph Classes
Journal of Graph Theory, Volume 110, Issue 2, Page 223-244, October 2025.ABSTRACT We show that every commutative idempotent monoid (a.k.a. lattice) is the endomorphism monoid of a subcubic graph. This solves a problem of Babai and Pultr and the degree bound is best‐possible. On the other hand, we show that no class excluding a minor can have all commutative idempotent monoids among its endomorphism monoids. As a by‐product,

A Dichotomy Theorem for Γ‐Switchable H‐Colouring on m‐Edge‐Coloured Graphs
Journal of Graph Theory, Volume 110, Issue 2, Page 200-208, October 2025.ABSTRACT Let G be a graph in which each edge is assigned one of the colours 1 , 2 , … , m, and let Γ be a subgroup of S m. The operation of switching at a vertex x of G with respect to an element π of Γ permutes the colours of the edges incident with x according to π.

Combs, Fast and Slow: Non‐Adiabatic Mean‐Field Theory of Active Cavities
Laser &Photonics Reviews, Volume 19, Issue 19, October 7, 2025.A unified mean‐field theory is developed that describes active cavities with dynamics of any speed, whether they be fast, slow, or anything in between. By creating an operator‐based framework that makes no adiabatic approximation, this approach delivers more efficient simulations and new analytical insights for a wide range of integrated combs, such as
