Thermostimulated Luminescence and Tunnel Luminescence, luminescence results from TL and TSL. The contribution of TL in the delayed luminescence of synthetic diamonds is 90% (Vins 1988; Yelisseyev and Sobolev 1979b; Yelisseyev 1977; Vins and Yelisseyev 1989; Yelisseyev et al. 1988). Most natural diamonds are capable of storing light-sums during external

Contrastive learning can learn general features of datasets from unlabeled data and autonomously discover latent structures in the data. Furthermore, dense retrieval methods based on

Alexander M. Zaitsev methods, while effective in some scenarios, encounter difficulties when attempting to handle the complexities of trust networks and the sparsity of trust relationships. Current techniques attempt to use user attributes such as ratings and reviews to fill these data gaps, although this approach can
