Edwardsiella piscicida is the causative agent of edwardsiellosis, which has caused enormous economic losses worldwide. In our previous research, an attenuated live vaccine known as WED and based on the virulent strain E. piscicida EIB202 can effectively protect turbots against edwardsiellosis via intraperitoneal injection, while vaccination by immersion exhibits a weaker effect. During the development of the immersion vaccine, we surprisingly found the counts of ΔpEIB202/ EIB202 colonized on zebrafish were 100 times lower than those of EIB202. However, pEIB202 carries 53 predicted ORFs and has several copies in E. piscicida EIB202, impeding the study of its function. Thus, the replication region is located at a 1,980 bp fragment (from 18,837 to 20,816 bp), containing a transcriptional repressor and a replication protein. Moreover, the minimal replication plasmid, named pRep-q77, has low copies in both E. coli and E. piscicida, but is more stable in E. piscicida than in E. coli. This work lays a foundation for further examination of the function of the virulence plasmid pEIB202.

Purpose- Despite the ongoing digital transformation, it is not clear whether emerging market firms follow their manufacturing FDI path in the emerging digital industries. This paper examines how digital orientation affects the location strategies in internationalization and how the existing innovation capacities moderate the link between digital orientation and the location strategies. Design/methodology/approach- This study chooses the Chinese setting for research design because digital transformation is already prevalent in the society and the cases of outward expansion are salient among the emerging markets. It uses the panel dataset of 976 Chinese listed firms that consists of 6,648 observations spanning from 2007 to 2017. Ordinary least square regression is used for the statistical approach with a one-year lag in the model. Findings- Digital orientation increases a likelihood of emerging multinationals’ entries in developed countries, and a high level of innovative capacities strengthens the link. Two groups seem to prefer entries in developed countries: firms with a high level of digital orientation with a high level of innovative capacities and firms with a low level of digital orientation, if with a low level of innovative capacities. The former reflects the context of digital transformation and the latter hints at the tax avoidance or interests in real estate. Research implications or originality -While emerging multinationals are known to prefer entries in developing countries for capacity arbitrage, our results forecast that their FDI strategies may have a drastic change as digital transformation deepens.

In this paper, the parameter estimation of bilinear state-space systems with missing outputs is studied. The bilinear model is transformed into a linear time-varying state-space model, and Kalman smoother with a timevarying gain is adopted to estimate missing outputs and unmeasurable states. Under the expectation-maximization (EM) algorithm scheme, an iterative estimation algorithm based on Kalman smoother is derived, in which the unknown parameters, missing outputs, and unmeasurable states can be estimated simultaneously. Two simulation examples, including a numerical example and a three-tank system experiment, are adopted to verify the effectiveness of the proposed algorithm.

Due to the complexity of the contaminations in wastewater, a universal adsorbent that takes many sorts of pollutant is desired. A multi-functioning magnetic Fe3O4-cored magnesium-aluminum layered double oxide (Fe3O4@LDO) composite was prepared and employed as an adsorbent for removing F-, Sb(III) and MO from water, respectively, which are three typical contaminants with different molecule sizes as water contamination. The effect of pH contact time and initial concentrations of pollutants on the removal rates of each contaminant were investigated. Fe3O4@LDO composite showed excellent adsorption performance for all of the three molecules F-, Sb(III) and MO, and their maximum adsorption capacities are as high as 258, 391, and 506mg/g, respectively. The adsorption process of F-, Sb(III) and MO on Fe3O4@LDO fitted well to Langmuir model and pseudo-second-order kinetic model. The adsorption mechanisms of F-, Sb(III) and MO on Fe3O4@LDO were investigated. We discovered that iron ions diffused from Fe3O4 nanospheres contributed to the good performance of the absorbent.

To improve the efficiency of the liquid metal magnetohydrodynamic (LMMHD) generator, a new type of magnet structure of LMMHD system is designed in paper. The internal magnetic gathering capability is enhanced by imitating the arrangement of the Halbach array magnet. The magnetic induction intensity of conventional magnetic channel, Halbach magnet channel, and the new type of magnet channel, which is derived from basic Halbach are compared via ANSYS Maxwell 2D model. Simulation results show that Halbach magnets have better capacity of magnetism gathering and are more efficient at gathering electricity than conventional methods. The new type of magnetic has advantages of small size, low cost, high induction intensity, high output voltage and high power.

The study, using A-share listed companies as samples, examines the influence of major Chinese religions (Confucianism, Buddhism, Taoism) on corporate ESG ratings. The research reveals a significant positive correlation between Confucian and Taoist philosophies and corporate ESG, suggesting that religious culture might serve as an alternative mechanism to encourage ESG participation in emerging markets. Additionally, the impact of Buddhism and Taoism on ESG ratings is slightly stronger than that of Confucianism, providing an opportunity for further exploration of cultural influences. The study broadens the scope of corporate social responsibility and offers new insights for global companies practicing ESG. Through comparative analysis of the impact of different religions on corporate ESG, it provides empirical evidence for cross-cultural research and practical guidance for businesses and policymakers. Recognizing the positive influence of religious culture on ESG can aid policymakers in formulating policies for sustainable social progress. Despite limitations, this study offers a novel perspective on how traditional Chinese culture influences corporate ESG ratings, providing valuable insights for businesses and policymakers.

OBJECTIVES Job strain is positively associated with incident hypertension, while increasing leisure-time physical activity (LTPA) can reduce incident hypertension. However, the joint associations of job strain and LTPA with incident hypertension among United States workers have yet to be investigated. This study examined the independent and joint associations of job strain and LTPA with incident hypertension. METHODS This prospective cohort study (n=1,160) utilized data from the population-based Midlife in the United States study. The associations of job strain and LTPA at baseline with incident hypertension during follow-up were examined using Cox proportional hazards models. High job strain was derived from a combination of high job demands and low job control, and high LTPA was defined as engagement in moderate or vigorous LTPA at least once per week. RESULTS During 9,218 person-years of follow-up, the hypertension incidence rate was 30.6 (95% confidence interval [CI], 27.3 to 34.3) per 1,000 person-years. High job strain was associated with a higher risk for hypertension than low job strain (adjusted hazard ratio [aHR], 1.29; 95% CI, 1.00 to 1.67). High LTPA was associated with lower hypertension risk than low LTPA (aHR, 0.77; 95% CI, 0.60 to 0.98). Hypertension risk was higher among workers with high job strain and low LTPA than among those with low job strain and high LTPA (aHR, 1.70; 95% CI, 1.18 to 2.43). CONCLUSIONS Job strain and LTPA showed positive and inverse associations, respectively, with incident hypertension. The combination of high job strain and low LTPA was associated with the highest risk for hypertension.
