Predicting Scattering From Complex Nano-Structures via Deep Learning by Yongzhong Li, Yinpeng Wang, Shutong Qi, Qiang Ren, Lei Kang, Sawyer D. Campbell, Pingjuan L. Werner, Douglas H. Werner

“…In this paper, we propose a DL framework for real-time predictions of the scattering from an isolated nano-structure in the near-field regime. We find that, to achieve precise approximation of the optical response obtained from numerical simulations, the proposed DL framework only requires a small training data set. …”

Sonographic Verification and Clinical Significance of the Features of Surrounding Structures in Knee Osteoarthritis by E. A. Skripnichenko, V. V. Lyalina, S. G. Pripisnova, V. G. Gоlubev

“…First of all, this is a variety of pain syndromes, among which is the pathology of periarticular structures (AS). To date, the contribution of this type to the clinical picture of OA has been sufficiently studied, primarily due to the fact that the list and frequency of these lesions have not yet been described.Aim: to describe the basis of the main periarticular structures in patients with different radiographic stages of knee OA according to ultrasound data.Materials and methods: The observational study has currently included 88 patients who had an outpatient appointment with a rheumatologist for knee osteoarthritis between 2021 and 2023. …”
