Online top N topics spread and competition

Abstract

This paper investigates the factors influencing the spread of popular topic competition from the perspective of propagation dynamics. The popularity of a topic is directly influenced by the level of people’s interest in it. The rarity, deviation and type can influence the level of interest in such topics. In addition, the topic publisher also has an impact on the competitive dissemination of the topic. The higher the rank of the original publisher is, the easier it spreads. Compared with small bloggers without fans, it is easier to attract people’s attention, and the heat of the topic will rise faster. The results show that the rarer the topic, the greater the deviation from reality, and the more followers the originator has, the more competitive it is.

Carbon Dots as Ligand Operons to Expand Cluster Size Distribution for High Load‐bearing Liquid Superlubricity

“…FTIR spectra of ILA 1:8 show that it integrates the characteristic peaks of Gly (i.e., C─OH at 1120‐1000 cm −1 ) and ChCl (i.e., C─OH at 1092 cm −1 and 865 cm −1 ); [ 42–44 ] moreover, the ─OH peak of ILA 1:8 at 3330 cm −1 is red‐shifted by 25 cm −1 with respect to the ‐OH peak (3355 cm −1 ) in Gly ( Figure a), suggesting that ILA 1:8 is formed due to the H‐bond interactions between Gly and ChCl. [ 45,46 ] For the optimized sample CDs 0.9 /ILA 1:8 (i.e., with the addition of CDs), the ─OH peak is further red‐shifted by 18 cm −1 from 3330 to 3312 cm −1 , [ 47 ] demonstrating that there is also strong H‐bond interactions between CDs and the components in ILA 1:8 . The chemical shift of the corresponding ‐OH is also shifted toward lower field strengths by 0.14 ppm relative to the ‐OH signal in Gly (Figure 2b); when the amount of CDs addition is decreased (i.e., CDs 0.6 /ILA 1:8 ) or annealed CDs containing fewer oxygen‐containing functional groups (e.g., ─OH/─COOH) are used as additives (i.e., annealed CDs 0.6 /ILA 1:8 ), the shift of the chemical shifts toward the low‐field direction gradually decreases (i.e., 0.12 and 0.08 ppm, respectively), demonstrating that the changes in the H‐bond interactions caused by CDs mainly exist between them and Gly in ILA 1:8 .…”
