Near‐Infrared Soliton Crystal Generation in Silicon Resonators

Laser &Photonics Reviews, EarlyView.
Near‐infrared Kerr soliton generation in silicon is severely hindered by two‐photon and free‐carrier absorption. By combining transverse‐mode dispersion engineering with active free‐carrier extraction, monolithic silicon resonators support densely spaced, low‐noise soliton‐crystal combs spanning over 100 nm and, in a separate device, broadband ...

Photonic Neuromorphic Processing With Coupled Spiking Silicon Microrings

Laser &Photonics Reviews, EarlyView.
A neuromorphic photonic core composed of three self‐pulsing silicon microring resonators is experimentally demonstrated for analogue and digital processing. Richer computational capabilities emerge under injection conditions where the dynamics are nonlinear and coupled, yet remain reproducible, opening novel strategies for future on‐chip training and ...

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

An Approach for Computationally Efficient Yet Accurate Modeling of Vibrating Machines With Neidhart Springs

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Accurate modeling of vibrating machines equipped with Neidhart springs is challenging due to the strong nonlinearities introduced by the elastomer–metal torsional elements and the constraints imposed by their kinematic arrangement. Multibody modeling methodologies for such vibrating machines are often computationally demanding, thus limiting ...

Islamic Public Administration in Practice: The Taliban's “Gender Apartheid” Governance in Afghanistan

Public Administration and Development, EarlyView.
ABSTRACT This article analyzes the Taliban's post‐2021 governance model through the Islamic Public Administration (IPA) framework, focusing on justice, equality, and women's inclusion. It asks: (1) How does the Taliban's governance align with core IPA principles?

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...
