Phase shift in skyrmion crystals [PDF]

open access: yesNature 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]

open access: yesScientific 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.

Sea Urchin Removal as a Tool for Macroalgal Restoration: A Review on Removing “the Spiny Enemies”

open access: yesFrontiers in Marine Science, 2022
Kelp and macroalgal forests provide the ecological foundations of many temperate rocky reef ecosystems, but have regionally declined, often due to sea urchin overgrazing and the formation of urchin barrens.

A Novel Isolated DC–DC Converter for High Step-Down Applications

open access: yesIEEE Access, 2023
This paper proposes a new isolated high step-down DC–DC converter based on the phase-shift full-bridge converter. The proposed converter has some properties very suitable for high step-down applications including a high step-down ratio, low ...

Effects of the Stony Coral Tissue Loss Disease Outbreak on Coral Communities and the Benthic Composition of Cozumel Reefs

open access: yesFrontiers in Marine Science, 2021
In the Caribbean, disease outbreaks have emerged as significant drivers of coral mortality. Stony Coral Tissue Loss Disease (SCTLD) is a novel white plague-type disease that was first reported off the Florida coast in 2014.

Color Digital Holography Based on Generalized Phase-Shifting Algorithm with Monitoring Phase-Shift

open access: yesPhotonics, 2021
Color digital holography (DH) has been researched in various fields such as the holographic camera and holographic microscope because it acquires a realistic color object wave by measuring both amplitude and phase.
