Forecasting Count Data With Varying Dispersion: A Latent‐Variable Approach

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Count data, such as product sales and disease case counts, are common in business forecasting and many areas of science. Although the Poisson distribution is the best known model for such data, its use is severely limited by its assumption that the dispersion is a fixed function of the mean, which rarely holds in real‐world scenarios.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Spatiotemporal dynamics of brain function network during proprioception rehabilitation after anterior cruciate ligament reconstruction: A randomized trial

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
The improvement of proprioceptive function after ACLR is related to the optimization of spatiotemporal dynamics of SM, CC, DM, CB and VI functional networks. Rehabilitation optimization can incorporate visual–cognitive dual‐task exercises. Abstract Purpose In this study, we aimed to examine the dynamic functional network connectivity (dFNC) patterns ...

Effect of Re or W Addition on the Oxidation Behaviour of a Compositionally Complex Ta–Mo–Cr–Ti–Al Alloy in Air at 1000°C

open access: yesMaterials and Corrosion, EarlyView.
The effect of addition of 3 at.% of either Re or W on the oxidation performance of equimolar Ta–Mo–Cr–Ti–Al is investigated and found to be beneficial, at least temporarily. Additionally, the oxide (Ti,Ta)O2 has been identified and characterised as a main part of the oxide scale. ABSTRACT Presuming that doping of protective (Cr,Ta,Ti)O2 with cations of

Effect of iron addition on the structure and tribological performance of CrAlN coatings Einfluss von Eisen‐Zugabe auf die Struktur und das tribologische Verhalten von CrAlN‐Beschichtungen

open access: yesMaterialwissenschaft und Werkstofftechnik, EarlyView.
Hard coatings mitigate friction and wear of engineering components, while tribochemical interactions between lubricant and coating strongly influence performance. Masking ferrous surfaces with a coating reduces the effectiveness of additives optimized for steel.
