Phase shift in skyrmion crystals [PDF]

Nature Communications, 2021
Skyrmions are a type of topological spin texture, which can exist as both an isolated state, and as a skyrmion crystal. Here, Hayami et al present a theoretical study of phase shifts in skyrmion crystals, showing how such phase shifts can lead to other ...

Theory and application of robust linear phase-shift algorithm for phase-shift deflectometry method [PDF]

Scientific Reports
Based on the polynomial theory, the error propagation characteristics of the widely used N-step discrete Fourier transform (N-DFT) phase-shift algorithm were analyzed via theoretical analysis, under the effect of Gamma distortion and phase detuning.

Performance Analysis of Hybrid Phase Shift Keying over Generalized Nakagami Fading Channels

Journal of Telecommunications and Information Technology, 2023
In addition to the benefits of hybrid phase shift keying (HPSK) modulation in reducing the peak to average power ratio of the transmitted signal to reduce the zero cross- ings and the 0◦-degree phase transmissions, HPSK enhances the bit error rate (BER)

Phase-shifted Adversarial Training

CoRR, 2023
Adversarial training has been considered an imperative component for safely deploying neural network-based applications to the real world. To achieve stronger robustness, existing methods primarily focus on how to generate strong attacks by increasing the number of update steps, regularizing the models with the smoothed loss function, and injecting the

Phase transitions in paradigm shift models. [PDF]

PLoS ONE, 2013
Two general models for paradigm shifts, deterministic propagation model (DM) and stochastic propagation model (SM), are proposed to describe paradigm shifts and the adoption of new technological levels.
