Generalized modulational instability in multimode fibers: wideband multimode parametric amplification

open access: yes, 2015
In this paper intermodal modulational instability (IM-MI) is analyzed in a multimode fiber where several spatial and polarization modes propagate. The coupled nonlinear Schr\"{o}dinger equations describing the modal evolution in the fiber are linearized ...

Two‐Step Clustering‐Based Equivalent Modeling of Large‐Scale Wind Farms for Enhanced Primary Frequency Regulation

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT The focus on wind power frequency regulation has largely been on individual wind farms, which presents challenges in meeting the coordinated operation needs of multiple stations within large‐scale installations. To address issues of model simplification and accuracy, we propose a large‐scale wind farm equivalent modeling method based on ...

Non-Markovianity in High-Dimensional Open Quantum Systems using Next-generation Multicore Optical Fibers [PDF]

open access: yesQuantum
With the advent of quantum technology, the interest in communication tasks assisted by quantum systems has increased both in academia and industry. Nonetheless, the transmission of a quantum state in real-world scenarios is bounded by environmental noise,

Mathematical Modeling and Experimental Evaluation of Heat and Mass Transfer During Pork Loin Roasting

open access: yesJournal of Food Process Engineering, Volume 49, Issue 2, February 2026.
A mechanistic porous‐medium model of pork loin roasting integrates heat and mass transfer with protein denaturation and anisotropy, predicting temperature, moisture, and swelling pressure. Dripping, rather than evaporation, is identified as the primary cause of weight loss, and the effects of oven humidity and anisotropy on cooking are quantified ...

Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation

open access: yesAdvanced Materials, Volume 38, Issue 3, 13 January 2026.
In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.
