Advanced Photonics Research, Volume 7, Issue 4, April 2026.We identify ruthenium as a refractory plasmonic material exhibiting dual ENZ optical topological transitions and dual plasmonic resonances spanning from visible to infrared region with high imaginary permittivity. We establish a nanoparticle‐on‐cavity (NPoC) resonance mode and realize a NPoC selective solar absorber using cost‐effective additive ...

The Case of Fleeting Orders and Flickering Quotes
Journal of Futures Markets, Volume 46, Issue 4, Page 629-652, April 2026.ABSTRACT The literature controversially discusses the ambiguous motives and driving forces behind quickly cancelled limit orders (fleeting orders), which are characteristic of high‐frequency markets. In particular, manipulative and dysfunctional characteristics are feared. We analyze top‐of‐book fleeting orders—so‐called flickering quotes—and show with
