Chemistry – A European Journal, EarlyView.Males of the tropical frog Gephyromantis granulatus carry unique ethyl‐branched sesquiterpenoid macrolactones in their scent glands. Their structure elucidation was performed by GC/MS, leading to the proposed structures of the granolides. A flexible enantioselective synthesis confirmed the structures and allowed determination of their absolute ...

Chemistry – A European Journal, EarlyView.DFT calculations on porphyrin, corrin, and corphin complexes of cobalt, rhodium, iron, manganese, or nickel, and QM/MM calculations on enzyme models, explore the factors controlling the availably of super‐reduced metal(I) states. True metal(I) states are seen in corrin only for cobalt, in corphin only for nickel, and not at all in porphyrin.

Asymptotic properties of cross‐classified sampling designs
Canadian Journal of Statistics, EarlyView.Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.

A partial envelope approach for modelling multivariate spatial‐temporal data
Canadian Journal of Statistics, EarlyView.Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.

Detecting communities when order and direction matter in social network analysis
Canadian Journal of Statistics, EarlyView.Abstract A novel algorithm combining both node degree and edge betweenness (node degree+edge betweenness) is developed to highlight gradients in connectivity. It identifies communities within complex directed graphs. These are networks that are composed of actors who have ties that originate and end at themselves (self‐loops).
