With the development of network information technology and the popularization of mobile terminal equipment, people's network practice activities are deepening day by day, and people's understanding has also undergone profound changes. The combination of ideological discourse power and cyberspace expands the source of discourse power, promotes the transformation of discourse subject, and also changes the mode of discourse transmission and the pattern of discourse power. In addition to using the state power to constrain people's behavior, the ruling class also needs to use the discourse system. Ideology can only express the will of the ruler if it is combined with the right to speak. The ideology of today's Chinese society should also reflect the characteristics of the times, reflect the mainstream value of society, and explore how to construct the ideology of contemporary China. As a response to the background of world multi-polarization, economic globalization, cultural diversity, and social information. The construction of discourse power in mainstream ideology has a real need to be strengthened in China. 展开更多

Physicists experimentalists use many observations of a phenomenon, which are the unknown equations that describe it, in order to understand the dynamics and obtain information on their future behavior. In this article we study the possibility of reproducing the dynamics of the phenomenon using only a measurement scale. The Whitney immersion theorem ideas are presented and generalization of Sauer for fractal sets to rebuild the asymptotic behavior of the phenomena and to investigate evidence of nonlinear dynamics in the reproduced dynamics using the Brock, Dechert, Scheinkman test (BDS). The applications are made in the financial market which are only known stock prices. 展开更多

In this Letter, a 116-actuator deformable mirror (DM) was used to correct the wavefront distortion in a 10.7 J, 10 Hz neodymium-doped yttrium aluminum gamet (Nd:YAG) slab amplifier. By applying a pump-light homogenizer to transform the 3x1 near-field beam array into an integrated beam, the beam quality was greatly improved from 5.54 times diffraction limit (TDL) to 1.57 TDL after being corrected by the DM. To the best of our knowledge, this is the first investigation on beam quality control of an arrayed near-field beam in high-energy diode-pumped solid-state lasers. 展开更多

Background: Athletes, coaches, sport psychology practitioners, and researchers suggest that mental toughness represents an important construct that is associated with athletic performance. Unfortunately, the absence of real-world performance as a dependent variable has limited our ability to substantiate this claim. The concern of a lack of ecologically valid measures of sports performance might be addressed by examining the relationship between mental toughness and sports performance using a standardized measure of personal best(PB) triathlon time and a validated unidimensional measure of mental toughness.Methods: Three hundred and sixteen triathletes completed the 8-item mental toughness index(MTI), reported their age, and provided a PB Olympic distance triathlon time and the total number of triathlons they had completed to date. Given that males are typically quicker than females, a standardized time was calculated by dividing the PB by the current Olympic record for gender;we also hypothesized that more experienced triathletes would report quicker PB times because of greater frequency and duration of training. Once we had controlled for gender and experience,we predicted that mental toughness would be negatively associated with triathlon time and the size of the relationship would be of a moderate magnitude.Results: Results revealed small-to moderate-sized negative relationships between both completed number of triathlons and mental toughness with standardized PB time.Conclusion: The hierarchical regression analysis showed that mental toughness provided a unique contribution to the variability in standardized Olympic triathlon PB after controlling for the total number of triathlons completed. 展开更多

Enhancing light–matter interaction in cavity quantum electrodynamics has aroused widespread interests in on-chip quantum information processing. Here, we propose a hybrid nanotoroid–nanowire system to enhance photon–exciton interaction. A nanoscale gap is formed by placing a dielectric nanowire close to a dielectric nanotoroid, where the coupling coefficient between photon and emitter can achieve 5.55 times of that without nanogap. Meanwhile, the cavity loss and spontaneous emission of the emitter will remain at a small value to guarantee the realization of strong coupling. The method might hold promise for the research of nanophotonics,quantum optics, and novel optical devices. 展开更多

The “Zhejiang spirit” refers to a theoretical summary of the group consciousness, mental state, value orientation and ideological realm, which is, as a motivating power, owned and recognized by all Zhejiang people, and carries Zhejiang peculiarities. President Xi Jinping, during his term of office in Zhejiang, launched a number of seminars and activities to seek “a Zhejiang spirit that moves with the times.” Forty years of reform and opening-up, the “Zhejiang spirit” has experienced an evolution that can be summarized as three improvements: from spontaneous formation to deliberate cultivation, from something limited to eastern Zhejiang to an integrating force that spans the entire Zhejiang Province, and from a mere existence to a role that functions adequately. The “Zhejiang spirit” is extracted from the humanistic spirits shaped in all corners of Zhejiang province. It is “an instrumental ensemble played across the entire province,” and represents a certain judgment and interpretation. The “Zhejiang spirit” not only describes and summarizes the past and present, but will also guide and motivate the future, and support people in their enterprising and industrious practices to move with the times. 展开更多

The maximum mating times were 3 for female and 4 for male. Average mating times were 1.06 for female and 0.91 for male. L-isoleucine methyl ester (LIME), a major comp onent of pherom one, in creased gradually from 14:00 and peaked at 19:00, then dropped sharply at 20:00 and remained low at 24:00.(R)-(-)-linalool (referred as linalool below) maintained similar levels throughout the study period. Calling and mating activity significantly decreased LIME titer, but not linalool. Analyses of 11 samples collected during calling days (20 d-70 d) revealed that LIME production was affected by female age. LIME titers in creased from 20 d to 45 d, and decreased from 45 d to 70 d. While lin alool titers remained at similar levels at all sampling dates. The highest ratio between LIME and lin alool was 12 and the lowest was 4. Field tests con firmed that the most attractive ratios of LIME: lin alool in early seas on (Ju ne 1 to 20) and late season (August 1 to 20) were 6:1, while in the most serious injury stage (June 20 to August 1) was 12:1. This is the first report about circadian rhythmicity of sex pheromone in Holotrichia parallela, which provides a basis for con trolling it in field. 展开更多

Objective: To study the pharmacokinetics of puerarin(PUE) in Gegen Qinlian Decoction(葛根芩连汤, GQD), and the effects of PUE dosage variations on the pharmacokinetics of baicalin(BAL) in mice. Methods: GQD is composed of the concentrated granules of four Chinese herbs. Three dosages with different levels of PUE, including GQD, GQD co-administered with PUE, and GQD co-administration with two times the amount of PUE, were used to research the pharmacokinetics of PUE and BAL in mice. The indirect competitive enzyme-linked immunosorbent assay(ic ELISA) methods based on an anti PUE-monoclonal antibody(MAb) and BAL-MAb were employed to determine the concentration of PUE and BAL in mice blood. Results: After the co-administration of GQD with PUE, the area under the curves(AUC0-14 h) of PUE increased 2.8 times compared with GQD. At the dose of GQD co-administration at two times that of PUE, the AUC0-14 h of PUE was almost equal to that of GQD co-administration of PUE, showing non-linear pharmacokinetics. The AUC0-48 h of BAL showed a good dose-related increase of PUE(r=0.993) in the range from 100 to 300 mg/kg, indicating that PUE dramatically affects the absorption of BAL in mice. There was no significant difference in the other pharmacokinetic parameters, such as the first time of maximum concentration(Tmax), the second Tmax, or the mean residence time. Conclusions: The ic ELISA methods were successfully applied to pharmacokinetic studies of PUE and BAL in GQD in mice. The dosage variability of PUE of the main ingredient in GQD affects its own pharmacokinetic characteristics and the absorption characteristics of BAL. 展开更多
