Aminated poly(ethylene glycol) methacrylate resins as stable heterogeneous catalysts for the aldol reaction in water
Habitat loss and fragmentation increase realized predator-prey body size ratios
In the absence of predators, habitat fragmentation favours large body sizes to facilitate gap crossing. The size of primary consumers is, however, also shaped by top-down effects as predators select prey of a certain size. Therefore, higher trophic levels should be taken into consideration when studying the effect of habitat loss and fragmentation ...
Evaluation of the American yam bean (Pachyrhizus spp.) for storage root yield across varying eco-geographic conditions i...
Open Access Article; Published online: 15 June 2019 / The American yam bean (Pachyrhizus spp.) is a legume crop that is exclusively used for its storage roots. The seeds are inedible due to presence of toxic rotenone. It produces high storage root yields comparable of major root crops like cassava or sweetpotato. And flower pruning more than double...
A CO2-tolerant perovskite oxide with high oxide ion and electronic conductivity
...
Mixed ionic–electronic conductors (MIECs) that display high oxide ion conductivity (σo) and electronic conductivity (σe) constitute an important family of electrocatalysts for a variety of applications including fuel cells and oxygen separation membranes. Often MIECs exhibit sufficient σe but inadequate σo. It has been a long‐standing challenge to ...
Dynamic output-feedback control for singular T-S fuzzy systems using fuzzy Lyapunov functions
In light of fuzzy weighting-dependent Lyapunov functions, a dynamic output-feedback control for singular T-S fuzzy systems is introduced. Based on a set-equivalence technique and fuzzy weighting-dependent Lyapunov functions, this paper derives a sufficient condition ensuring the singular T-S fuzzy systems to be admissible (regular, impulse-free and...
Multi-objective predictive control optimization with varying term objectives : a wind farm case study
This paper introduces the incentive of an optimization strategy taking into account short-term and long-term cost objectives. The rationale underlying the methodology presented in this work is that the choice of the cost objectives and their time based interval affect the overall efficiency/cost balance of wide area control systems in general. The ...
Epoxide ring-opening reaction promoted by ionic liquid reactivity: interplay of experimental and theoretical studies
Ionic liquids (ILs) have been widely introduced recently into the epoxide ring-opening reaction as catalysts or solvent without considering the chemical stability of ILs in propylene oxide (PO). Through a combination of electrospray-ionization quadrupole time-of-flight mass spectrometry (ESI-QTOF-MS) investigations and quantum-chemical calculations...

Transonic buffet instability: From two-dimensional airfoils to three-dimensional swept wings
The objective of the present study is to explain the evolution of the transonic buffet phenomenon from two-dimensional airfoils to three-dimensional swept wings by a global stability analysis. With respect to two-dimensional buffet, shock oscillation frequency increases by a factor of 4 to 7 in the case of a swept 30◦ wing and three-dimensional pat...
The Evolutionary Arms Race between Virus and NK Cells: Diversity Enables Population-Level Virus Control.
Published in Viruses
Viruses and natural killer (NK) cells have a long co-evolutionary history, evidenced by patterns of specific NK gene frequencies in those susceptible or resistant to infections. The killer immunoglobulin-like receptors (KIR) and their human leukocyte antigen (HLA) ligands together form the most polymorphic receptor-ligand partnership in the human g...
