Exact Dynamics of the SU(K) Haldane-Shastry Model

open access: yes, 1999
The dynamical structure factor $S(q,\omega)$ of the SU(K) (K=2,3,4) Haldane-Shastry model is derived exactly at zero temperature for arbitrary size of the system.

Cave Palaeolithic of the Ural Mountains – a review

open access: yesBoreas, Volume 55, Issue 1, Page 4-28, January 2026.
The Ural Mountains are of fundamental importance for studying early human migrations along the geographical limits between Europe and Asia. Geological processes and past climates gave rise to numerous caves, mostly in Palaeozoic carbonate formations.

Food web reconstruction of Barmaky, the oldest post‐LGM hunter‐gatherer site in north‐western Ukraine

open access: yesBoreas, Volume 55, Issue 1, Page 182-197, January 2026.
The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.

Simultaneous Superconducting and Antiferroquadrupolar Transitions in PrRh$_{2}$Zn$_{20}$

open access: yes, 2012
Superconducting and antiferroquadrupolar (AFQ) transitions in a Pr-based compound PrRh2Zn20 have been found to occur simultaneously at Tc=TQ=0.06 K. The superconducting transition manifests itself by zero resistance and large diamagnetic susceptibility ...

Monoaminergic modulation of photoreception in ascidian:evidence for a proto-hypothalamo-retinal territory [PDF]

open access: yes, 2012
Background : The retina of craniates/vertebrates has been proposed to derive from a photoreceptor prosencephalic territory in ancestral chordates, but the evolutionary origin of the different cell types making the retina is disputed.

From Floral By‐Product to Bioactive Resource: Phytochemical Profiling and Antioxidant Potential of Crocus sativus Stamens

open access: yesFood Science &Nutrition, Volume 13, Issue 12, December 2025.
This study highlights the phytochemical richness and nutritional value of Crocus sativus stamens, characterized through UHPLC–MS/MS and GC–MS analyses. The extracts and fractions showed significant antioxidant potential, supported by multiple in vitro assays.
