Phyllocephalum keralense (Asteraceae) a new species from southern Western Ghats of Kerala, India

open access: yesNordic Journal of Botany, EarlyView.
A new species of Phyllocephalum is described and illustrated from Palakkad district of Kerala, India. The new species shows similarity to P. rangacharii but differs with respect to key floral traits, viz. ovoid shape of the capitula, involucral bracts in 3 series, inflated receptacle and ovoid 6‐ribbed ovary with 5–6 densely barbellate pappus setae ...

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

open access: yesJournal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.
