Human craniosynostosis syndromes, resulting from activating or neomorphic mutations in fibroblast growth factor receptor 2 (FGFR2), underscore an essential role for FGFR2 signaling skeletal development. Embryos harboring homozygous null die prior to skeletogenesis. To address the of normal bone development, a conditional gene deletion approach was adopted.

The origin of anomalous Hall effect (AHE) in magnetic materials is one the most intriguing aspect condensed matter physics and has been controversial for a long time. Recent studies indicate that intrinsic AHE closely related to Berry curvature occupied electronic states. In Weyl semimetal with broken time-reversal symmetry, there are significant contributions on around nodes, which would lead large AHE. Here, we report half-metallic ferromagnet Co3Sn2S2 single crystal. By systematically...
Variation of electrical resistance in single-crystalline Ni50Mn50−xInx alloys (x=14–16) upon martensitic transformation was investigated. In Ni50Mn35In15 with Tm∼295K, a negative magnetoresistance (MR) over 60% is attainable at moderate field strengths; Ni50Mn34In16 Tm∼190K, the MR can exceed 70% temperature approximately 100K. The significant change electric originates primarily from altered electronic structure, while large effect magnetic follows its ability to manipulate materials low Tm...

Layered kagome-lattice 3d transition metals are emerging as an exciting platform to explore the frustrated lattice geometry and quantum topology. However, typical kagome electronic bands, characterized by sets of Dirac-like band capped a phase-destructive flat band, have not been clearly observed, their orbital physics even less well investigated.
