Summary: In this paper, a first-order distributed optimization algorithm that is robust to Byzantine failures is proposed. The algorithm models each agent's state as a two-state Markov chain and employs three layers of defense to achieve temporal and spatial robust aggregation, as well as gradient normalization. The method is applicable for convex and smooth non-convex cost functions and provides convergence guarantees.

Summary: This paper presents a sensitive microwave near-field sensor based on utilizing a three-dimensional capacitor within a planar split-ring resonator, which enhances sensitivity in detecting dielectric fluids. Experimental testing shows higher sensitivity in detecting the presence of chloroform and dichloromethane, as well as changes in fluid levels. The proposed sensor offers improved performance compared to planar resonators, with increased electric field enhancement and higher loaded-quality factor achievable.

Summary: Surface phonon polaritons (SPhPs) are coupled photon-phonon excitations that strongly influence the optical and thermal behavior of nanomaterials. By using a scanning transmission electron microscope with a highly monochromated electron beam, varying SPhP signatures from nanoscale MgO cubes can be visualized and used to tomographically reconstruct the phononic surface electromagnetic fields of the object. This 3D information offers insights into nanoscale physical phenomena and is valuable for the design and optimization of nanostructures for new uses.

Summary: This letter presents a novel method, called distributed interferometric ISAR (D-InISAR), for three-dimensional imaging of ship targets. The method combines distributed inverse synthetic aperture radar (ISAR) and interferometry techniques to enhance azimuth resolution and improve coordinate reconstruction accuracy. The paper introduces a novel D-InISAR configuration, a phase correction method, and a 3-D imaging algorithm based on D-InISAR. It also proposes a new evaluation criterion to quantify reconstruction accuracy. Numerical simulations are conducted to verify the effectiveness and robustness of the proposed algorithm.

Summary: This study utilized a generative deep-learning model, variational-autoencoder (VAE), to randomly generate realistic three-dimensional schistous sand particles and confirmed the statistical agreement with natural sand particles, demonstrating the fidelity and validity of the trained VAE model. The effectiveness and controllability of the generation process were verified by adding Gaussian random noise and conducting linear interpolation to the latent variables. The methodology has the potential for generating other geological entities and modeling complicated engineering geological processes, beyond just serving as a clump template for the Discrete Element Method (DEM).
