This work aims to study the influence of religion on the “zero-dose” vaccination status of children aged 12 - 23 months in Benin and Togo. Methods: This was a cross-sectional study which consisted in carrying out secondary analyzes using the databases of the most recent editions of the Demographic and Health Surveys in Benin and the Multiple Indicator Cluster Surveys (MICS) in Togo. We extracted data concerning the vaccination status (“1 = zero-dose”, “0 = vaccinated”) of the children, the religious affiliation of the head of the household or the mother and other variables related to the child, the mother, the household and the environment. By means of a logistic regression, the adjusted effect of the religious affiliation of the head of the household or of the mother on the vaccination status at “zero-dose” was determined. Results: A total of 2430 and 933 children were respectively included in the study on behalf of Benin and Togo. The prevalence of “zero-dose” vaccination status in children aged 12 - 23 months was 33.91% (95% CI = 31.67 - 36.23) in Benin and this prevalence was 26.88% (95% CI = 23.50 - 30.55) in Togo. In Benin, there is no evidence in favour of the influence of the religious affiliation of the mother on the “zero-dose” vaccination status of children. In Togo, children living in households whose head was Muslim (ORa = 3.44;95% CI = 1.29 - 9.13) were more likely to be “zero-dose” than those coming from households run by individuals with no religious beliefs. Conclusion: Further research is needed to understand the basis for the excess risk of “zero-dose” vaccination status in children that appears to be associated with the Muslim religion.展开更多

This letter presents an enhanced low-light enhancer for UAV nighttime tracking based on Zero-DCE++ due to its ad-vantages of low processing cost and quick inference. We developed a light-weight UCBAM capable of integrating channel information and spatial features and offered a fully considered curve projection model in light of the low signal-to-noise ratio of night scenes. This method significantly improved the tracking performance of the UAV tracker in night situations when tested on the public UAVDark135 and compared to other cutting-edge low-light enhancers.

By this method, several same or similar time-varying components are arranged according to certain rules along the time axis. The synthesized command can suppress the arbitrary unwanted vibration harmonic while achieving the desired rigid body motion. The number of the components increases rapidly when the number of harmonic vibration is growing. In this article, the CSVS based on zero-placement technique is used to construct the synthesized command to suppress the multi-harmonics simultaneously in the discrete domain. The nature of zero-placement method is to put enough zeros to cancel system poles at necessary points. The designed synthesized command has equal time intervals between each component and which is much easier to be implemented. Using this method, the number of components increases linearly with the increasing of the number of being suppressed harmonics. For the spacecraft with flexible appendages, CSVS based on zero-placement is used to design the time optimal large angle maneuver control strategy.
