Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes
Advanced Science, Volume 13, Issue 13, 3 March 2026.Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Three‐Dimensional Heterogeneous Bonding for High‐Density and Low‐Noise TMR Sensing Arrays
Advanced Science, Volume 13, Issue 13, 3 March 2026.This study demonstrates a three‐dimensional heterogeneous bonding approach to fabricate compact TMR sensing units with double junction numbers and improved magnetic performance. Optimized Au─Au bonding and angled etching improve device integrity, noise characteristics, and magnetoresistance.

Linguistic Evidence Suggests that Xiōng‐nú and Huns Spoke the Same Paleo‐Siberian Language
Transactions of the Philological Society, Volume 124, Issue 1, Page 29-52, March 2026.Abstract The Xiōng‐nú were a tribal confederation who dominated Inner Asia from the third century BC to the second century AD. Xiōng‐nú descendants later constituted the ethnic core of the European Huns. It has been argued that the Xiōng‐nú spoke an Iranian, Turkic, Mongolic or Yeniseian language, but the linguistic affiliation of the Xiōng‐nú and the ...

Low-Complexity Detection of High-Order QAM Faster-Than-Nyquist Signaling
IEEE Access, 2017 Faster-than-Nyquist (FTN) signaling is a promising non-orthogonal transmission technique to considerably improve the spectral efficiency. This paper presents the first attempt in the literature to estimate the transmit data symbols of any high-order ...
