Diversity and distribution of gall-forming aphids of the genus Pemphigus (Sternorrhyncha: Aphididae, Pemphigini) in Eastern Siberia

open access: yesJournal of Asia-Pacific Biodiversity, 2020
We reviewed the diversity and distribution of the gall-forming aphids of the genus Pemphigus developing on poplars in Eastern Siberia. As a result, the checklist of this group was compiled comprising 13 species distributed in this macroregion that ...

Single and multi-objective real-time optimisation of an industrial injection moulding process via a Bayesian adaptive design of experiment approach

open access: yesScientific Reports
Minimising cycle time without inducing quality defects is a major challenge in injection moulding (IM). Design of Experiment methods (DoE) have been widely studied for optimisation of injection moulding, however existing methods have limitations ...
