    Precise and interpretable neural networks reveal epigenetic signatures of aging across youth in health and disease by David Martínez-Enguita, Thomas Hillerton, Julia Åkesson, Daniel Kling, Maria Lerm, Mika Gustafsson

    Published 2025-01-01
    “…While traditional models are effective, their interpretability is limited by their dependence on small and potentially stochastic sets of CpG sites. Here, we propose that the reliability of DNAm age clocks should stem from their capacity to detect comprehensive and targeted aging signatures.MethodsWe compiled publicly available DNAm whole-blood samples (n = 17,726) comprising the entire human lifespan (0–112 years). …”

    Silicon photonic modulators with a 2 × 1 Fabry–Perot cavity by Cao Hengzhen, Xie Jin, Sun Weichao, Zhu Mingyu, Xiang Yuluan, Zhang Gong, Guo Jingshu, Shi Yaocheng, Dai Daoxin

    Published 2025-01-01
    “…In particular, the straight modulation section in the FP cavity is broadened to be far beyond the single-mode regime, alleviating the inherent sensitivity to the variations of waveguide dimensions and thus reducing stochastic resonance-wavelength variations. The Q factor of the FP cavity is manipulated by optimally manipulating the reflection of the AMWGs, and the modulation bandwidth is enhanced to be over 40 GHz by utilizing the optical peaking enhancement effect, which happens when operating at the wavelength slightly detuning to its resonance wavelength. …”
