From this point of view, we compare constraints on cosmological parameters, Omega m and Omega Lambda, using the Yonetoku and the Amati relation calibrated by low-redshift GRBs with z < 1.8. We found that they are different in 1-sigma level, although they are still consistent in 2-sigma ...

Heisenberg’s uncertainty relation (HUR)1is one of the pillars of quantum mechanics and it sets the limit of how precisely one can predict the outcome of the measurements of two non-commuting observables. While the relation itself is a simple consequence of Born’s rule and the operator chara...
The connection between generalized Einstein’s relation and weak ergodicity breaking can be established. A few conditions were already established that guaranteed the ergodic hypothesis33,34 but none were sufficient for aging systems. From Eq. (3), we find that \({\lim }_{| {t}_{1}-{t}_...

and employs a convolutional neural network to capture global relationships and transitional characteristics between entities and relations in the knowledge graph. However, it only utilizes the triple information, and ignores the rich information contained in relation paths. In fact, a path of one relati...
