Advanced Robotics Research, EarlyView.This work presents the MicroRoboScope, a highly integrated, compact, and portable microrobotic experimentation platform combining electromagnetic and acoustic actuation with real‐time visual feedback into a single, end‐to‐end device. The system enables closed‐loop control and tracking algorithm experimentation within an accessible and unified hardware ...

Advanced Science, EarlyView.Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Advanced Science, EarlyView.Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).

A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators
Advanced Science, EarlyView.This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.

On the postage stamp problem with the three stamp denominations.
MATHEMATICA SCANDINAVICA, 1980 In the ``postage stamp problem'', one considers an integral basis \(A_k\) of elements \(1 = a_1 < a_2 < \cdots < a_k\), and studies representations \(\sum x_ia_i\), \(x_i\ge 0\), where the number \(\sum x_i\) of addends does not exceed a certain integer \(h\) (the ``size of the envelope'').
