Green's Functions of Non‐Hermitian Systems at Exceptional Deficiency
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).

Bioinspired Metastable Transient Peeling for Repeatable Rapid Release
Inspired by the explosive seed ejection of the squirting cucumber, this work introduces metastable transient peeling that temporally regulates stored interfacial energy release via a tunable energy barrier. A viscoelastic hemispherical gripper achieves 52 ms ultrafast, residue‐free release with 300 000‐cycle durability, enabling damage‐free handling of

High‐Temperature Magnetic Field Mapping Using a Single‐Crystal Diamond MEMS Resonator Array
A single‐crystal diamond MEMS resonator array enables magnetic‐field reconstruction with millisecond response, nanotesla level magnetic noise, and stable operation up to 573 K. Two‐ and three‐dimensional magnetic field mapping are demonstrated using ΔEeffect sensing, highlighting the potential of diamond MEMS technology for hightemperature magnetic ...

Retrospective Grid Cells in the Medial Entorhinal Cortex Encode Past Paths During Spatial Navigation
Retrospective grid cells are identified in the medial entorhinal cortex, with spatial firing patterns that become most grid‐like when activity is projected onto recently traversed locations. Their coding loses spatial precision in darkness and is disrupted during assisted movement, indicating that entorhinal representations incorporate recent path ...
