Universal gap growth for Lyapunov exponents of perturbed matrix products

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract We study the quantitative simplicity of the Lyapunov spectrum of d$d$‐dimensional bounded matrix cocycles subjected to additive random perturbations. In dimensions 2 and 3, we establish explicit lower bounds on the gaps between consecutive Lyapunov exponents of the perturbed cocycle, depending only on the scale of the perturbation.

Do auditory deviants evoke cortical state changes under anaesthesia? A proof‐of‐concept study

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 2148-2162, 1 April 2026.
Abstract Context‐dependent sensory processing within the predictive coding framework relies on detecting mismatches between incoming stimuli and internal predictive models. Sensory deviants elicit prediction errors, seen as enhanced neural responses, that update these models and influence attention and behaviour.

6‐Methylsulfinylhexyl isothiocyanate activates carbonic anhydrase‐dependent HCO3−/H+/Na+/Ca2+ transport via SLC4As–NHE–NCX–PMCA axis in odontoblasts

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 2816-2844, 1 April 2026.
Abstract figure legend 6‐Methylsulfinylhexyl isothiocyanate (6‐MSITC, hexaraphane), a wasabi sulfinyl compound, activates intracellular carbonic anhydrase (CA)‐mediated sequential HCO3−, Na+, H+ and Ca2+ transport through an activation axis involving HCO3−‐transporting solute carrier family 4 (SLC4As), the Na+–H+ exchanger (NHE), the Na+–Ca2+ exchanger

Intermittent Fasting Enhances Genome Integrity and Cytoprotective Pathways via (BHB) β‐Hydroxybutyrate Signaling and Chromatin Remodeling

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Repeated intermittent fasting elevates hippocampal β‐hydroxybutyrate (BHB), remodels HDAC activity and histone acetylation, and drives a metabolic–epigenetic transition from transient chromatin priming after a single fast to a sustained cytoprotective program associated with reduced DNA damage and enhanced genome maintenance.

Lack of GPNMB Is Associated With Altered Lipid and Glucose Metabolism and Disrupted Diurnal Hepatic Glycogen Regulation

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Loss of GPNMB function in mice fed a high‐fat/high‐fructose diet aggravated adiposity and dyslipidemia while preserving systemic glucose tolerance. This phenotype was associated with impaired hepatic AKT–FOXO1 signaling, increased NF‐κB activation, altered glycogen metabolism, and rhythmic disturbances in energy expenditure and clock gene expression ...
