Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

open access: yesOikos, EarlyView.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Numerical Simulation of Three‐Dimensional Unsteady Extrudate Swell Through Annular Dies: Effects of Die Core Opening Position and Sag on Parison Formation

open access: yesPolymer Engineering &Science, EarlyView.
Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.

The Influence of Irradiation Wavelength on the Growth of Polymer Brushes by SI‐PET‐RAFT Polymerization

open access: yesJournal of Polymer Science, EarlyView.
The use of SI‐PET‐RAFT has been gaining momentum for producing thick, homogenous, functional polymer brushes, in an oxygen‐tolerant manner. However, the connection between irradiation wavelength and the brush height has not been clear. Herein, we systematically explore the effect of irradiation wavelength on the resulting brush properties, finding a ...

Hybrid Nanoparticles Separated by Buoyant Density in a Large‐Scale Centrifugal Process

open access: yesJournal of Polymer Science, EarlyView.
Zonal rotors, shaped like hollow bowls, can sort mixtures of macromolecules and polymer nanoparticles based only on their densities, regardless of their actual sizes or shapes. Using these rotors can make a big difference because they do not need to use centrifuge tubes.

Toward Ultrawide Bandgap Engineering: Physical Properties of an α‐(TixGa1−x)2O3 Material Library

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The material system α‐(TixGa1−x)2O3 has potential applications in optoelectronics as it theoretically offers a bandgap tunable over a wide range from 0.14 to 5.6 eV. In the present work, spatially addressable material libraries of (TixGa1−x)yOz are realized using combinatorial material synthesis.

Statistical Complexity of Quantum Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...
