Drawing on the dual theory of narcissism and the conservation of resources theory, this study aimed to explore the relationship between narcissistic duality traits (narcissistic admiration and narcissistic rivalry) and organizational citizenship behavior of college students, and to further examine the mediating role of impression management motivation (assertive impression management motivation and defensive impression management motivation) and the moderating roles of teamwork, interpersonal relationships, and optimism.Methods: We used the questionnaire method with a sample of undergraduate and graduate students from several universities in Hubei, China. The data sample for analysis consists of 583 college students.Results: (1) Narcissistic admiration had a significant and positive effect on college students’ organizational citizenship behavior, while the effect of narcissistic rivalry was significant and negative; (2) assertive impression management motivation mediated the relationship between narcissistic admiration and college student’s organizational citizenship behavior, and defensive impression management motivation mediated the relationship between narcissistic rivalry and college student’ s organizational citizenship behavior; and (3) teamwork, interpersonal relationships, and optimism positively moderated the relationship between narcissistic admiration and assertive impression management motivation, and these variables positively moderated the indirect effects of assertive narcissism on college student’s organizational citizenship behavior through assertive impression management motivation.Conclusion: We found that college students with narcissistic admiration engaged in more organizational citizenship behaviors than those with narcissistic rivalry. In addition, narcissistic admiration had a positive effect on organizational citizenship behavior through assertive impression management motivation, and narcissistic rivalry had a negative effect on organizational citizenship behavior through defensive impression management motivation. Finally, teamwork, interpersonal relationships, and optimism significantly and positively mediated the relationship between narcissistic admiration and assertive impression management motivation, and the indirect effect of narcissistic admiration on organizational citizenship behavior through assertive impression management motivation. However, the direct effects of teamwork, interpersonal relationships, and optimism on the relationship between narcissistic rivalry and defensive impression management motivation, and the indirect effect of narcissistic rivalry on organizational citizenship behavior through defensive impression management motivation were not significant.Keywords: narcissistic admiration, narcissistic rivalry, impression management motivation, college student, organizational citizenship behavior

Introns, as important vectors of biological functions, can influence many stages of mRNA metabolism. However, in recent research, post-spliced introns are rarely considered. In this study, the optimal matched regions between introns and their mRNAs in nine model organism genomes were investigated with improved Smith–Waterman local alignment software. Our results showed that the distributions of mRNA optimal matched frequencies were highly consistent or universal. There are optimal matched frequency peaks in the UTR regions, which are obvious, especially in the 3′-UTR. The matched frequencies are relatively low in the CDS regions of the mRNA. The distributions of the optimal matched frequencies around the functional sites are also remarkably changed. The centers of the GC content distributions for different sequences are different. The matched rate distributions are highly consistent and are located mainly between 60% and 80%. The most probable value of the optimal matched segments is about 20 bp for lower eukaryotes and 30 bp for higher eukaryotes. These results show that there are abundant functional units in the introns, and these functional units are correlated structurally with all kinds of sequences of mRNA. The interaction between the post-spliced introns and their corresponding mRNAs may play a key role in gene expression.

Objective. To investigate the effectiveness of moxibustion combined with Chinese medicine in the treatment of spleen and stomach deficiency cold-type gastroparesis by meta-analysis and to provide the clinical basis for its treatment. Methods. A computer search of eight databases was performed for published and unpublished randomized controlled trials on moxibustion for spleen and stomach deficiency cold-type stomach pain from domestic and international clinical trial centers. The study was divided into a combination of a moxibustion and Chinese medicine group and a regular Western medicine group, and the outcome indicators were “effective” and “ineffective.” The relative risk (RR) was used as the effect indicator for the dichotomous data, and the meta-analysis was performed using Reviewer Manager 5.4 and Stata17.0 software. Results. A total of 8 randomized controlled studies with 729 patients were included, and all studies were analyzed for comparability of patients’ baseline information, with no statistically significant differences found (P>0.05). The meta-analysis results showed that the pooled effect size RR for the eight studies was 1.24 (95% confidence interval 1.16–1.32), and the statistical significance test was Z = 6.69 (P

The quantum circuit mapping approach is an indispensable part of the software stack for the noisy intermediatescale quantum (NISQ) device. It has a significant impact on the reliability of computational tasks on NISQ devices. To improve the overall fidelity of physical circuits, we propose a quantum circuit mapping method based on multi-agent cooperation. This approach considers the Spatio-temporal variation of quantum operation quality on the NISQ device when inserting ancillary operation. It consists of two core components: the qubit placement algorithm and the qubit routing method. The qubit placement algorithm exploits the iterated local search framework to find a desirable initial mapping for the reduced symmetric form of the original circuit. The qubit routing method generates the physical circuit through multi-agent communication and collaboration. Each agent inserts the ancillary gates independently according to its environment state. The quality of the physical circuit evolves according to an information-exchanging mechanism between agents, which combines the local search and global search. To experiment on the benchmark circuits (with hundreds of quantum gates) beyond the capacity of current NISQ devices, we build a noisy simulator with gate error 10x lower than that of the latest NISQ device of IBM. The experimental results confirm the performance of our approach in improving circuit fidelity. Compared with the stateof-the-art method, our method can improve the success rate by 25.86% on average and 95.42% at maximum., Comment: 13 pages, 10 figures

The oxidation behavior of 316L stainless steel exposed at 400, 600 and 800 °C air for 100, 500 and 1000 h was investigated using different characterization techniques. Weight gain obeys a parabolic law, but the degree of deviation of n index is increasingly larger with the increase of temperature. A double oxide film, including Cr2O3 and Fe2O3 oxide particles in outer and FeCr2O4 oxides in inner, is observed at 400 °C. As regards to samples at 600 °C, a critical exposure period around 100 h exists in the oxidation process, at which a compact oxide film decorated with oxide particles transforms to a loose oxide layer with a pore-structure. In addition, an oxide film containing Fe-rich outer oxide layer and Cr-rich inner oxide layer is observed at 600 °C for 500 and 1000 h. Spallation of oxide scale is observed for all samples at 800 °C regardless of exposure periods, resulting in different oxidation morphologies, and the degree of spallation behavior is getting worse. A double oxide film with the same chemical composition as 600 °C is observed, and the thickness increases over exposure periods.

Various subgroups of CD8+ T lymphocytes do not only demonstrate cytotoxic effects, but also serve important regulatory roles in the body's immune response. In particular, CD8+ regulatory T cells (CD8+ Tregs), which possess important immunosuppressive functions, are able to effectively block the overreacting immune response and maintain the body's immune homeostasis. In recent years, studies have identified a small set of special CD8+ Tregs that can recognize major histocompatibility complex class Ib molecules, more specifically Qa-1 in mice and HLA-E in humans, and target the self-reactive CD4+ T ce lls. These findings have generated broad implications in the scientific community and attracted general interest to CD8+ Tregs. The present study reviews the recent research progress on CD8+ Tregs, including their origin, functional classification, molecular markers and underlying mechanisms of action.

Four complexes Nd(C2F5COO)3Tfpy, Nd(C3F7COO)3Tfpy, Nd(C2F5COO)2(C6F5COO)Tfpy, and Nd(C2F5COO)3Phen were synthesized to investigate the effects of different ligands on fluorescent properties of Nd3+. Their structures were characterized by UV absorption spectra, FT-IR spectra and 1H NMR spectra. On the basis of testing absorption spectra, photoluminescence spectra and emission decay curves of each solution of the complexes, Judd-Ofelt(JO) analysis was carried out for each fluorescent solution. Structure analysis indicates that all ligands have successfully coordinated with central rare earth ions. Relatively small Ω2 obtained through JO analysis demonstrates that the coordination bonds between Nd3+ and the vicinity ligand are ionic for four complexes. The benzene rings of ligands are favorable for improving the fluorescence quantum efficiency of Nd3+. Compared with Phen, Tfpy is an excellent neutral second ligand because it has more asymmetric chemical structure and less hydrogen atoms. The four Nd(III)complexes all have potential to become liquid laser material because of their large stimulated emission cross sections.

The Ordos Basin is one of the most important oil and gas basins in China. Based on surface outcrop, key exploratory wells and seismic reflection data and by using the technology of “prototype basin recovery”, seismic profile “layer flattening” and “restoration of balanced section”, and other methods, the sedimentary boundary, structure and the evolution history of the Tianhuan depression on the western margin of the Ordos Basin are reestablished. The following results have been obtained. (1) The west boundary of the Late Triassic Ordos Basin was far beyond the scope of the current basin. The basin is connected with the Late Triassic Hexi Corridor Basin, and its western margin did not have tectonic characteristics of a foreland basin. (2) The Tianhuan depression was first formed in the Late Jurassic. At the late stage it was impacted by the late Yanshanian and Himalayan tectonic movement and the depression axis gradually moved eastwards to the present location with a cumulative migration distance of ∼30 km. (3) Eastward migration of the depression axis caused adjustment and even destruction of the originally formed oil and gas reservoirs, so that oil and gas remigrated and aggregated, resulting in secondary structural reservoirs formed at high positions on the western flank of the depression.
