Abstract: Weiss (1) points on our article (2). He observes that the Delingha tree-ring δ 18 O record matches KM-A speleothem δ 18 O record from the Mawmluh Cave in India, that de fi nes the… read more here.

DOI: 10.1126/sciadv.adr4161
Abstract: Here, we use 7437 stable oxygen (δ18O) isotope ratios extracted from 192 living and relict Alpine trees to reconstruct trends and extremes in European summer hydroclimate from 8980 before the present to 2014 Common Era.… read more here.

DOI: 10.11650/tjm/221104
Abstract: Let $R$ be the Ehrhart ring of the stable set polytope of a cycle graph which is not Gorenstein. We describe the non-Gorenstein locus of $\mathrm{Spec} R$. Further, we show that $R$ is almost Gorenstein.… read more here.
