Food Safety and Health, Volume 4, Issue 4, Page 783-804, October 2026.Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

A Dislocated Quasi-Normed Space and Its Completeness for A Fixed Point Theorem
مجلة بغداد للعلومA concept of a dislocated quasi-normed space is introduced in this paper which is a spatial case of the concept of a quasi-normed space and related to the notion of a dislocated quasi-metric space.

The Banach-Saks Properties in Orlicz-Lorentz Spaces
Abstract and Applied Analysis, 2014 The Banach-Saks index of an Orlicz-Lorentz space Λφ,w(I) for both function and sequence case, is computed with respect to its Matuszewska-Orlicz indices of φ. It is also shown that an Orlicz-Lorentz function space has weak Banach-Saks (resp., Banach-Saks)

Curved RUM spectra of periodic frameworks
Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract The rigid unit mode (RUM) spectrum records the phases at which a periodic (or crystal) framework admits a phase‐periodic infinitesimal motion. This plays a central role in the geometric rigidity of crystal frameworks, with applications in crystallography and materials science.

Lipschitz‐free spaces over uniformly discrete metric spaces are 3‐Schur
Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract We prove that the Lipschitz‐free space over any uniformly discrete metric space has the 3‐Schur property.

Antiproximinal Norms in Banach Spaces
Journal of Approximation Theory, 2002 A closed convex subset \(C\) of a Banach space \((X,\| \;\| )\) is called antiproximinal if no point outside \(C\) has a nearest point in \(C\). This is equivalent to the property supp \(C \cap NA_{ \| \;\| }= \{0\}\), where supp \(C\) denotes the set of all support functionals of the set \(C\) and \(NA_{ \| \;\| }=\, \)supp \(B_ {\| \;\| }\) are the ...

Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract We characterize the extreme and exposed points of the unit ball (with respect to the L1$L^1$‐norm) in the shift‐invariant space generated by the Gaussian function, as well as in the quasi‐shift‐invariant space generated by the hyperbolic secant.
