Advanced Science, EarlyView.Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

International Journal of Railway, 2012 Many different types of floating slab track have been developed and installed around the world to reduce vibrations and noise originating in the surrounding environment. The main objective of this study is to examine the influence of slab length on behavior of floating slab track based on rail-slab-isolator interaction.

Programmable Topological Magnetic Textures in Above‐Room‐Temperature 2D Ferromagnet Fe3GaTe2
Advanced Science, EarlyView.This work demonstrates the programmable generation and deterministic modulation of magnetic skyrmion bags with high‐order topological numbers in the above‐room‐temperature 2D ferromagnet Fe3GaTe2 (FGaT) via current‐pulse control. Furthermore, highly efficient electrical manipulation and current‐driven parallel motion of these high‐order topological ...

Advanced Science, EarlyView.Inspired by antifreeze glycoproteins (AFGPs), we synthesized a type of oligomeric cellulose (OC‐8) to inhibit ice formation and enlarge the inter‐ice water channel for transportation. Typical confocal fluorescence experiments display the expansion of the ice‐water interface for zinc‐ion transport.

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2
Advanced Science, EarlyView.NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Slab track optimisation considering dynamic train–track interaction [Elektronisk resurs]
, 2021 Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can

Advanced Science, EarlyView.A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.

Measurement of slab track behaviour at different sites
, 2019 Measured train passages and hammer impacts in combination with track-soil calculation have been successfully used for the detection of damaged slab tracks. This approach is now extended to intact slab and ballast tracks.
