Wavelength-Spacing Adjustable Dual-Wavelength Dissipative Soliton Resonance Thulium-Doped Fiber Laser by Simin Liu, Zuxing Zhang, Jianping Shen, Kehan Yu

“…A dual-wavelength dissipative soliton resonance thulium-doped fiber laser based on nonlinear optical loop mirror (NOLM) has been demonstrated. In this laser, mode-locking is achieved based on equivalent saturation absorption of the NOLM, while the dual-wavelength operation is attributed to the online birefringent fiber filter composed of a polarizer and a section of polarization-maintaining fiber (PMF). …”

Optimizing active suspension systems with robust h∞ control and adaptive techniques under uncertainties by Kumlachew Yeneneh, Menelik Walle, Tatek Mamo, Yared Yalew

“…The novel architecture overcomes fundamental limitations in conventional systems by simultaneously addressing (i) parametric uncertainties through structured robustness margins (μ < 1 for ±25 % variations in mass/stiffness), (ii) unstructured road disturbances via adaptive gain scheduling, and (iii) resonant vibrations using closed-loop FFT analysis with 50 ms spectral updates. The controller's dual-degree-of-freedom design introduces a breakthrough solution where the H∞ core guarantees stability while the adaptive module dynamically adjusts damping ratios and stiffness coefficients through Lyapunov-based parameter estimation, achieving 40 % faster convergence than fixed-gain alternatives. …”

Lipid metabolites affected by deficient autophagy antagonize the occurrence of autophagy through AMPK signaling in insects by Ling Tian, Qien Zhong, Yubei Yang, Wenmei Wu, Yang Xiao, Sheng Li, Kang Li

“…Conversely, the metabolites accumulated due to dysfunctional autophagy inhibit autophagy occurrence by downregulation of AMPK signaling, thereby forming a regulatory loop in insects. Collectively, our results provide valuable insights into applications for beneficial insects and pest management, while also present potential chemicals applied on human diseases related to autophagy or lipid metabolism.…”
