Assessing the Meshing for Windage Power Loss Simulations of an Orthogonal Face Gear
MachinesIn the current energy landscape, efficiency is a critical topic. Therefore, even in the case of geared transmissions, it is essential to predict and calculate power losses as accurately as possible from the design phase. There are mainly three categories

Why Do Voters Demand Universal Government Benefits? [PDF]
Universal social benefits seem to contradict important notions in economics. They are poorly targeted and must be paid for by what seem to be high taxes.

Advanced Functional Materials, EarlyView.A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Outdoor test stand performance of a convertible engine with variable inlet guide vanes for advanced rotorcraft propulsion [PDF]
A variable inlet guide van (VIGV) type convertible engine that could be used to power future high-speed rotorcraft was tested on an outdoor stand. The engine ran stably and smoothly in the turbofan, turboshaft, and dual (combined fan and shaft) power ...

Advanced Functional Materials, EarlyView.A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Advanced Functional Materials, EarlyView.A modular biosynthetic PVA–gelatin hydrogel crosslinked via visible‐light thiol‐ene chemistry is engineered as a coating for neural electrodes. Optimizing matrix composition and mechanical properties enables the hydrogel to support astrocytic populations that guide neural differentiation and functional maturation.

Churning of R&D personnel and innovation [PDF]
This paper explores the role of R&D worker mobility on innovation performance. As one main novelty, we employ churning as a measure for worker mobility. Churning depicts the number of workers which are replaced by new ones.

Advanced Functional Materials, EarlyView.Inspired by the skin‐toughening mechanism of marine sponges, an ion‐orchestrated structural engineering strategy is proposed to regulate the surface microstructure of hydrogel coatings, enabling the in situ formation of a robust armor layer that enhances mechanical integrity and provides multifunctional protection by suppressing fouling attachment and ...
