Modelling Mobile IP with Mobile Petri Nets [PDF]

, 2009
Mobile systems explore the interplay between locality and connectivity. A subsystem may have a connection to a remote subsystem and use this for communication. It may be necessary or desirable to move the subsystem close to the other in order to communicate. Alternatively, the method of communication may vary depending on proximity.

Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides

Advanced Materials, EarlyView.
This work introduces an approach to defect‐mediated symmetry breaking and built‐in polarization in nominally centrosymmetric defective oxides, Gd‐doped CeO2‐δ films, by controlling macroscopic charge asymmetry. Electric field‐driven asymmetric redistribution of oxygen vacancies induces a switchable, stable polarization, leading to a notable, persistent

Revealing the Altermagnetism in Hematite via XMCD Imaging and Anomalous Hall Electrical Transport

Advanced Materials, EarlyView.
This study combines X‐ray magnetic imaging and electrical transport to uncover the anomalous Hall effect in hematite, an insulating oxide exhibiting unconventional altermagnetic properties. Imaging reveals distinct magnetic domains linked to crystal symmetry, and angular‐dependent transport measurements highlight unusual symmetry‐driven conductivity ...
