Generation of Ultrafast Attosecond Magnetic Field from Ne Dimer in Circularly Polarized Laser Pulses

By numerically solving time-dependent Schr?dinger equations,we investigate the generation of electron currents,ultrafast magnetic fields and photoelectron momentum distributions(PMD) when circularly polarized laser pulses interact with a Ne dimer in the charge migration(CM) process.By adjusting the laser wavelength,we consider two cases:(i) coherent resonance excitation(λ=76 nm) and(ii) direct ionization(λ=38 nm).The results show that the current and magnetic field generated by the Ne dimer under resonance excitation are stronger than under direct ionization.This phenomenon is due to the quantum interference between the initial state 2pσ_(g) and the excited state 3sσ_(g) under resonance excitation,so the CM efficiency of the dimer can be improved and the strength of the PMD under different ionization conditions is opposite to the strength of the electron current and induced magnetic field.In addition,we also find that both 2pπ_(g) and 2pπ_(u) have coherent resonance excitation with 3sσ_(g) state and generate periodic oscillating currents for the Ne dimer.The study of the dynamics of the Ne dimer under different ionization conditions lays a foundation for research of ultrafast magnetism in complex molecular systems.

The effect of Jinlong capsule on the immune function for intervened patients with primary liver cancer

Objective: The aim of this study was to evaluate the effect of Jinlong capsule on the immune function for intervened patients with primary liver cancer. Methods: Matched the inclusion criteria, 60 patients were selected and randomly divided into two groups. The treatment group had 30 cases treated with Jinlong capsule combined with the transcatheter arterial chemoembolization(TACE); the control group had 30 cases treated with TACE. Each group was treated 30 days as a cycle, which had completed at least two cycles. Indicators of cellular immune function about the activity of CD3, CD4, CD8, CD4/CD8 and natural killer(NK) cell were detected before and after treatment, then to compare and analysis with each other. Results: Before treatment, the activity of peripheral blood CD3, CD4, CD8, CD4/CD8 and NK cell in the two groups was no significant difference(P > 0.05); after treatment, the activity of CD3, CD4 and NK cell in the treatment group was significantly increased, the ratio of CD4/CD8 increased, and the value of CD8 decreased(P < 0.05), the activity of CD3, CD4 and NK cell in the control group was significantly decreased, the ratio of CD4/CD8 decreased(P < 0.05), and the value of CD8 slightly higher than before treatment(P > 0.05), the difference between the two groups indicated the statistical significance(P < 0.05). Incidence of gastrointestinal reactions, leucopenia, hemoglobin, platelet decline in the treatment group was lower than those in the control group, but without presenting the statistical significance(P > 0.05). Conclusion: Jinlong capsule with hepatic arterial infusion chemotherapy can improve the patients' immune function, and reduce the adverse reactions of interventional chemotherapy. Hence,it deserves to be promoted in clinically.

Omnichannel retail operations with ship-to-store and ship-from-store options under supply disruption

Omnichannel retailing strategies are widely used in practice and have been extensively studied in recent years, but few studies have explored omnichannel retailing operations in response to supply disruption in the post-pandemic era. To fill this gap, this study explores whether the adoption of omnichannel fulfillment options (i.e., ship-from-store and ship-to-store options) can mitigate the risk of supply disruption in a supply chain where a retailer orders products from a reliable supplier and a risky supplier, respectively. Under the omnichannel retailing strategy, the retailer’s order quantity from the risky supplier may increase or decrease while that from the reliable supplier may increase. Interestingly, it is possible to achieve a win–win–win outcome when the supply disruption risk is high and the market share of the channel offered by the risky supplier is low. Moreover, the entire supply chain benefits from the omnichannel retailing strategy even if it faces a high level of disruption risk.
