    • Enhancing russian handwriting recognition VIA transfer learning and data augmentation with VGG-BiLSTM-CTC 

      Liu, J.; Dang, Z.; Xiong, S. (БНТУ, 2025)
      The VGG-BiLSTM-CTC model has succeeded in many languages, yet Russian handwriting recognition is understudied despite its demand. This research adapts the model to Russian through transfer learning to address this gap.

    • Thermal Lensing and Multiwatt Microchip Laser Operation of Yb:YCOB Crystals 

      Loiko, P.; Serres, J. M.; Mateos, X.; Yu, H.; Zhang, H.; Liu, J.; Yumashev, K.; Griebner, U.; Petrov, V.; Aguilo, M.; Diaz, F. (2016)
      Thermal lensing is studied in monoclinic Yb:Ca4YO(BO3)(3) (Yb:YCOB) oxoborate crystals cut along the optical indicatrix axes. For all orientations, the thermal lens is positive. In the Z-cut crystal, the sensitivity factors of the thermal lens are MZ-X = 2.4 and MZ-Y = 2.8 m(-1)/W (for E parallel to X), and the astigmatism degree is as low as S/M = 14%. The positive thermal lens ...
