Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
Advanced Functional Materials, EarlyView.ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Advanced Functional Materials, EarlyView.A fully transparent, all‐metal‐oxide neuromorphic transistor using a sodium‐embedded alumina (SEA) electrolyte is demonstrated. By precisely tuning the thermal annealing process, the chemical composition of the SEA layer is controlled, allowing for the deterministic realization of both short‐term and long‐term synaptic plasticity within the same device

Sigma-delta modulation neural networks
, 1993 Sigma-delta modulation can be used to model the waveforrn coding process of biological neurons. The discrete-time model can greatly simplify the analysis that are nontrivial with traditional continuous time models formulated with differential equations ...

Efficient Trellis Sigma-Delta Modulation
, 2011 In chapter eight, an efficient derivative of the Trellis sigma-delta modulator, called the Efficient Trellis sigma-delta modulator, is introduced. Instead of exploring 2 N solutions in parallel, only M solutions out of the possible 2 N are tracked.

Hexagonal Sigma-Delta Modulation
, 2003 A novel application and generalization of sigma--delta (61) modulation has emerged in three-phase power-electronic converters. A conventional modulator with scalar signals and binary quantizer is generalized to a modulator with vector signals and a
