With the development of electrification and intelligent technology, including electric vehicles, intelligent robots, grid energy storages, etc., increasingly high requirements have been put forward for energy storage technology [1], [2], [3], [4]. Among various energy storage devices, lithium-ion batteries have gradually taken a dominant position due to their advantages such as high energy density, multiple cycles and fast charge–discharge process [5], [6], [7].

AbstractAlthough biological studies increasingly rely on embeddings of single cell profiles, the quality of these embeddings can be challenging to assess. Such evaluations are especially important for avoiding mis- leading biological interpretations, assessing the accuracy of integration methods, and establishing the zero-shot capabilities of foundational models. Here, we posit that current evaluation metrics can be highly misleading.

Abstract We report the experimental observation of the spin-wave moiré edge and cavity modes using Brillouin light scattering spectromicroscopy in a nanostructured magnetic moiré lattice consisting of two twisted triangle antidot lattices based on an yttrium iron garnet thin film. Spin-wave moiré edge modes are detected at an optimal twist angle and with a selective excitation frequency.
