A Magnetic‐Driven Self‐Rotation‐Stabilized Miniature Swimming Robot
Advanced Science, EarlyView.Inspired by the stable rotational descent of seeds in nature, this study designs a magnetic‐driven self‐rotation‐stabilized miniature swimming robot (MSMSR). Based on a resonance‐driven strategy, the robot exhibits high swimming performance, offering enhanced directional swimming and improved resistance to water flow disturbances compared to existing ...

Successive Interference Cancellation for Bandlimited Channels With Direct Detection
IEEE Transactions on CommunicationsThe maximum information rates for bandlimited channels with direct detection are achieved with joint detection and decoding (JDD), but JDD is often too complex to implement. Two receiver structures are studied to reduce complexity: separate detection and decoding (SDD) and successive interference cancellation (SIC).

Osseoperceptive EMG Feedback Improves Grasp Force Control in Myoelectric Prosthetic Hands
Advanced Science, EarlyView.Osseoperception is explored as a non‐invasive pathway for delivering sensory feedback in myoelectric prosthetic control. By encoding the user's electromyographic (EMG) signal through bone‐conducted stimulation, this approach enables predictive grasp force regulation.

Advanced Science, EarlyView.In GdMn2O5, sublattice‐resolved EXAFS and diffraction analysis reveal pronounced spin‐phonon coupling and an unexpected opposing pressure response: the Mn‐driven Néel temperature slightly decreases while the Gd‐sublattice ordering temperature rises under pressures up to 0.86 GPa.

Green's Functions of Non‐Hermitian Systems at Exceptional Deficiency
Advanced Science, EarlyView.We analyze the responses of a non‐Hermitian lattice system under the condition of exceptional deficiency (ED), when all bands in the system are formed by exceptional points. Using the frequency domain, we identify novel steady‐state responses that root in the broadband super‐Lorentzian Green's function (GF).

Antenna subset selection for V-BLAST systems based on permutation and QR decomposition
Tongxin xuebao, 2006 A novel antenna subset selection in V-BLAST systems with ordered successive interference cancellation （OSIC） detection was presented. With an eye to the impacts of ordering and cancellation, by use of permutation and QR decom-position, a terse antenna ...
