Ligand‐Level Chemical Activation: Coordination with Benefits

European Journal of Inorganic Chemistry, EarlyView.
While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups

Modelling of the Marine Traffic Situation Complexity [PDF]

MATEC Web of Conferences, 2016
With the growth of traffic density, traditional collision risk models cannot thoroughly describe the complex traffic any more. Therefore, in this paper, a marine traffic situation complexity model, which is based on the relationship between ships, is introduced to metric the complexity of vessel traffic.

Nowcasting World Trade With Machine Learning: A Three‐Step Approach

Journal of Forecasting, EarlyView.
ABSTRACT We nowcast world trade using machine learning, distinguishing between tree‐based methods (random forest and gradient boosting) and their linear‐regression‐based counterparts (macroeconomic random forest and gradient boosting—linear). While much less used in the literature, the latter are found to outperform not only the tree‐based techniques ...

Off-peak truck deliveries at container terminals: the 'Good Night' program in Israel [PDF]

, 2016
Purpose – Avoiding truck congestion and peaks in landside activity is one of the challenges to container terminal managers. The spreading of truck arrivals at terminals can be facilitated by widening the opening hours of terminals at the landside. Israel’

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...
