Invertibility of finite group homomorphic sequential systems

open access: yesInformation and Control, 1975
A class of systems, introduced by Brockett and Willsky, that evolve homomorphically on finite groups is considered. A general result, extending the linear sequential circuit Hankel matrix result of Massey and Sain, is derived. Also, an analog of the Brockett—Mesarovic result is obtained when we restrict our attention to abelian group systems.

Precise Microstructural and Stoichiometric Control Advances Flexible Ag2Te Thin‐Film Thermoelectrics for Wearable Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Flexible Ag2Te thin films achieving a record‐high mobility of 4756 cm2 V−1 s−1 and a peak power factor of 18.5 µW cm−1 K−2 are developed via precise structural control. The assembled flexible devices demonstrate excellent mechanical stability and ultrafast voltage response, enabling precise thermal detection when integrated into a robotic gripper for ...

Phase Diagrams Enable Solid‐State Battery Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but

A sequential coloring algorithm for finite sets

open access: yesDiscrete Mathematics, 1999
Let \(X\) be a finite set and \(P\) a hereditary property associated with the subsets of \(X\). A partition of \(X\) into \(n\) subsets each with property \(P\) is said to be a \(P\)-\(n\)-coloring of \(X\). The minimum \(n\) such that a \(P\)-\(n\)-coloring of \(X\) exists is defined to be the \(P\)-chromatic number of \(X\), denoted by \(\chi _{P}(X)\

LFA: A Lattice Fourier Analyzer for Quantitative In Situ EC‐STM of Adsorbate–Substrate Superstructures

open access: yesAdvanced Materials Interfaces, EarlyView.
Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

open access: yesAdvanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.
