New transformation of Wigner operator in phase space quantum mechanics for the two-mode entangled case

As a natural extension of Fan's paper (arXiv: 0903.1769vl [quant-ph]) by employing the formula of operators' Weyl ordering expansion and the bipartite entangled state representation we find new two-fold complex integration transformation about the Wigner operator (in its entangled form) in phase space quantum mechanics and its inverse transformation. In this way, some operator ordering problems can be solved and the contents of phase space quantum mechanics can be enriched.Comment: 8 pages, 0 figure

Is Web3 Better Than Web2 for Investors? Evidence from Domain Name Auctions

Blockchain-based assets are commonly believed to attract new investors. To investigate this claim, we compared investor preferences for Web2 and Web3 domain name auctions by analyzing daily auction patterns in Namecheap and OpenSea. Our results indicate that Web3 platforms may attract extreme investors with low or high values as a niche market. We found a significantly higher number of bids per auction, higher average bid prices, and greater price spreads on OpenSea, but a significantly lower number of unique bidders per auction. Our findings highlight the importance of considering the auction platform\u27s characteristics and asset context when evaluating bid patterns and predicting bid prices. This study serves as a starting point for future research in this emerging market and offers directions for further investigation

Efficacy of combined glucocorticoid and hyperbaric oxygen therapy against delayed encephalopathy after carbon monoxide poisoning, and its effect on expression of immune-associated cytokines

Purpose: To study the efficacy of glucocorticoid combined with hyperbaric oxygen therapy for the treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP), and its effect on the expression of immune-associated cytokines.Methods: A total of 102 DEACMP patients in PLA General Hospital, Haidian, China were divided into two groups of 51 patients each, namely, observation group (glucocorticoid + hyperbaric oxygen therapy), and control group (hyperbaric oxygen only). The clinical data for each group was retrospectively analyzed. Clinical efficacy, improvement time, hospitalization time, cognitive function, activities associated with daily living, changes in immunity-associated cytokines, and incidence of adverse reactions were compared for the two groups.Results: Following treatment, the time taken for improvement, duration of hospitalization, cognitive function, daily living activity and total effectiveness in the observation group were significantly higher than those for the control group (p < 0.05). In addition, the levels of transforming growth factor beta 1 (TGF- β1), interleukin 4 (IL-4) and interferon-gamma (IFN-γ) in the observation group were significantly greater than for the corresponding control group levels (p <0.05). There was no significant difference in incidence of adverse reactions between the two groups (p > 0.05).Conclusion: These results suggest that a combination therapy of glucocorticoid and hyperbaric oxygen therapy for the treatment of DEACMP is more eutherapeutic in the improvement of cognitive function and activities of daily living in DEACMP patients than hyperbaric oxygen therapy. The mechanism of this combination therapy may be related to the improvement in immunity-related cytokine levels.Keywords: Glucocorticoid, Hyperbaric oxygen, Delayed encephalopathy after carbon monoxide poisoning, Efficacy, Immunit
