Constrained HRT Surfaces and their Entropic Interpretation

open access: yesJournal of High Energy Physics
Consider two boundary subregions A and B that lie in a common boundary Cauchy surface, and consider also the associated HRT surface γ B for B. In that context, the constrained HRT surface γ A:B can be defined as the codimension-2 bulk surface anchored to

Implications of holdfast availability and patchiness on juvenile seahorse (Hippocampus reidi) condition and welfare: Simulations in captivity

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 552-561, December 2022., 2022
Abstract Seahorses (Genus Hippocampus; Family Syngnathidae) are iconic fish characterised by tails with prehensile capabilities, which develop after the transition from planktonic to benthonic lifestyle. As a result, seahorses remain attached to vegetal structures or other elements most of the time, both in the wild and under rearing conditions. In the

Rigid Macroporous Wood Microparticles Impart Universality and Scalability to Lightweight Foam Insulation

open access: yesAdvanced Sustainable Systems, EarlyView.
Rigid, lightweight foams for thermal insulation are produced using a universal and scalable method: results are compared between pilot plant trials, four wood residues, pulp, ocean water, and a biosurfactant. Two guidelines for using this method are suggested: use a distribution of rigid wood microparticle sizes and shapes and match the average ...
