    A Novel Grouting Diffusion Monitoring System Based on ZigBee Wireless Sensor Network by Xiangpeng Wang, Tingkai Wang, Jinyu Gao, Meng Yang, Fanqiang Lin, Yong Jia

    Published 2025-04-01
    “…It consists of multichannel data acquisition units with electrodes for sensing underground currents and a user control unit for centralized management and data processing. A system acquisition performance test confirmed that the differential input channel’s equivalent input noise of the ADC was only 175 μV and 188 μV, and the average error of the captured sine wave data was 4.51 mV and 4.19 mV, ensuring the voltage measurement accuracy of the data acquisition units. …”

    Neural SHAKE: geometric constraints in neural differential equations by Justin S. Diamond, Markus A. Lill

    Published 2025-08-01
    “…This technique generates lower-energy molecular conformations, enables more efficient subspace exploration, and formally subsumes classifier-guidance-type methods by treating geometric constraints as strict algebraic conditions within the diffusion process. Scientific Contribution Neural SHAKE formulates exact manifold‑projected score‑based diffusion : each reverse-SDEincrement is orthogonally projected, via a Lagrange-multiplier solve, onto the constraint surfaceσₐ(x)=0 for a = 1,…, A, with A the number of independent constraints and thus the manifold’scodimension . …”
