Aqueous and Surfactant-Free Synthesis of Nanoscale Covalent Organic Frameworks. [PDF]
Angew Chem Int Ed EnglWe report an aqueous, surfactant‐free, and versatile synthesis method for imine‐linked nanoCOFs incorporating porphyrin units, with tunable size and morphology. The resulting nanoCOFs exhibit excellent aqueous dispersibility, strong light absorption, and significantly enhanced photocatalytic activity.

Climate Change Challenges Grey Wolf Resilience: Insights From Dental Microwear. [PDF]
Ecol LettWe investigate dietary plasticity in European grey wolves across interglacial periods using dental microwear texture analysis. Enhanced durophagy is associated with warm climates in both modern Polish and British Pleistocene wolves, indicating deep‐time behavioural flexibility.

Implications of diet for the extinction of saber-toothed cats and American lions. [PDF]
PLoS ONE, 2012 The saber-toothed cat, Smilodon fatalis, and American lion, Panthera atrox, were among the largest terrestrial carnivores that lived during the Pleistocene, going extinct along with other megafauna ∼12,000 years ago.

Quantitative model checking of continuous-time Markov chains against timed automata specifications [PDF]
, 2009 We study the following problem: given a continuous-time Markov chain (CTMC) C, and a linear real-time property provided as a deterministic timed automaton (DTA) A, what is the probability of the set of paths of C that are\ud accepted by A (C satisfies A)?

Dynamic characteristics and processing of fillers in polyurethane elastomers for vibration damping applications [PDF]
, 2011 Polyurethane elastomers have the potential of being used to reduce vibrational noise in many engineering applications. The performance of the elastomer is directly related to matching the nature of the mechanical loss characteristics to the frequency and
