Evaluation of Withaferin A Content in Withania somnifera Using NMR and HPLC: A Comparative Assessment of Traditional and PCSL Extraction Methods

open access: yesChemistry &Biodiversity, Volume 23, Issue 6, June 2026.
A comparative evaluation of traditional aqueous extractions and innovative pressurised cyclic solid–liquid extraction is presented for Withania somnifera leaves. Quantitative NMR, validated by HPLC, reveals a markedly enhanced preservation and recovery of withaferin A using PCSL.

Untangling Colour Diversity: Ecogeographic Patterns in Two Scolopendra Species Revealed by Citizen Science

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using citizen‐science records, we analysed ecogeographic patterns of colour polymorphism in two closely related centipede species across Japan. While two colour morphs in Scolopendra mutilans are broadly sympatric, they are geographically restricted in S. japonica despite overlapping climatic niches and biotic interactions.

Measurement of digital photographic image quality : survey of psychophysics just noticeable threshold difference method

open access: yes, 2016
: The modeling and quantification of digital photographic image quality has, from a psychophysics perspective, traditionally followed two paths, one of which is the discriminable small or just noticeable difference (local psychophysics) as detected in an

Severity of Onion Tearing and Chemosensory Sensitivity: A Preliminary Investigation

open access: yesLaryngoscope Investigative Otolaryngology, Volume 11, Issue 3, June 2026.
ABSTRACT Objectives Involuntary tearing is an annoyingly common consequence of cutting onions. Little is known about who experiences so‐called “onion tears” and to what extent they experience them. Our aim with this study was to explore whether the degree of onion tearing is a phenotypic predictor of olfactory function and trigeminal sensitivity ...

Mathematical Models in Theoretical Psychophysics: A Historical Perspective

open access: yes
According to Robert Cummins, the primary explananda of psychology are mental capacities. One fundamental capacity—studied in psychophysics—is the ability to perceive aspects of the physical world.

Estimating Interoceptive Sensitivity from Physiological Breathing Parameters

open access: yesJournal of the Royal Society of New Zealand, Volume 56, Issue 3, June 2026.
Impairments in interoception (the process of sensing, perceiving, and interpreting internal stimuli from the body) are considered characteristic of many mental health conditions. Although there is a growing body of interoceptive research, accounting for the inherent physiological variability associated with interoceptive stimuli is a key challenge ...
