On integrable structures on non–compact boundaries in three–dimensional gravity

We study three-dimensional Einstein gravity with negative cosmological constant on non-compact spatial boundaries within the Chern-Simons formulation. Using an exact fluid/gravity correspondence, we derive a closed radial flow equation for the quasi-local stress tensor and show t...

Rod photoreceptors have a dual dependency on both aerobic glycolysis and OXPHOS and diverge metabolically from other retinal neurons

The retina metabolizes glucose into lactate, a hallmark of aerobic glycolysis known as the Warburg effect. Although evidence points to rod photoreceptors as the primary source of aerobic glycolysis, a comparison of the energy metabolism in different retinal neurons has yet to be...

Maxwell kinematical algebras and 3D gravities

Abstract In this paper, we present a Maxwell extension of kinematical Lie algebras by promoting the contraction method underlying the Bacry and Lévy-Leblond cube to a semigroup expansion framework. Within this approach, we show that both non- and ultra-relativistic Maxwell algebr...

Effect of Freeze Concentration on the Process Parameters, Physicochemical Properties, Total Bioactive Compounds and Antioxidant Capacity of Almond Milk

The objective of this study was to evaluate the application of centrifugal block freeze concentration (CBFC) in fresh almond milk to obtain a concentrated liquid sample with enhanced chemical composition, total bioactive compounds (TBC), antioxidant activity, and process paramete...

Rare Diseases as Epistemic Objects: Exploring the Moral Role of Health Systems

ABSTRACT This article explores how rare diseases reveal the moral and epistemic foundations of healthcare systems. Based on narrative interviews with 11 Chilean patients and 10 professionals, this study shows how the absence of standardised protocols—such as clinical guidelines,...
