A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

Time Series Decomposition Using Wavelet and Fourier Transforms for Enhanced Solar Flare Forecasting
Time series decomposition enables the extraction of meaningful components by filtering out irrelevant or noisy frequencies. This study investigates the use of four transformation techniques—three wavelet-based (Haar, Symlets, Daubechies) and one Fourier-

Reduction of speckle in digital holography by discrete Fourier filtering [PDF]
We present a digital signal processing technique that reduces the speckle content in reconstructed digital holograms. The method is based on sequential sampling of the discrete Fourier transform of the reconstructed image field.

Controlled Growth of Boron Nitride in Various Phases
Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...

Pricing Early-Exercise and Discrete Barrier Options by Fourier-Cosine Series Expansions [PDF]
We present a pricing method based on Fourier-cosine expansions for early-exercise and discretely-monitored barrier options. The method works well for exponential Levy asset price models. The error convergence is exponential for processes characterized by

core
A dyed nylon fiber is implemented inside the scattering phantom and skin tissue. The deep‐tissue light generation via whispering gallery mode lasing is demonstrated, achieving a depth of >50 times transport mean free path in scattering phantom and 3 mm beneath skin.
