The Difference

In this work, the linear correlation between the initial growth rate of COVID-19 contagion and the average Y-DNA haplogroup percentages in different countries is computed. In the case of haplogroup R1b, a positive correlation with high confidence level is found. Utilizing the maximum R1b percentages in place of the average ones, a more significant result is obtained. Considering an extended R1b data set, correlations with even higher confidence level are found (p-values 3.94E-7 and 2.40E-9, respectively). Repeating the same procedure for the initial growth rate of deaths, similar results are obtained (p-values 9.17E-11 and 2.18E-12, respectively). Furthermore, the correlation of haplogroup R1b with cases and deaths per capita is calculated over a five-month period, obtaining comparable results (e.g. p-value 2.45E-17 on April 10th). The difference between the correlation with maximum R1b percentages and the correlation with average ones is decreasing over time. Finally, assuming the possible involvement of R1b carriers, three scenarios are outlined according to their passive or active role in the spread of the virus.

BACKGROUND: It has not yet been tested whether averaged gain values and the presence of pathological saccades are significantly altered by manual data selection or if data selection only done by the incorporated software detection algorithms provides a reliable data set following v-HIT testing. OBJECTIVE: The primary endpoint was to evaluate whether the averaged gain values of all six SCCs are significantly altered by manual data selection with two different v-HIT systems. METHOD: 120 subjects with previously neither vestibular nor neurological disorders underwent four separate tests of all six SCCs with either EyeSeeCam® or ICS Impulse®. All v-HIT test reports underwent manual data selection by an experienced ENT Specialist with deletion of any noise and/or artifacts. Generalized estimating equations were used to compare averaged gain values based on unsorted data with averaged gain values based on the sorted data. RESULTS: EyeSeeCam®: Horizontal SCCs: The estimate and the p-value (shown in parenthesis) for the right lateral SCC and the left lateral SCC were 0.00004 (0.95) and 0.00087 (0.70) respectively. Vertical SCCs: The estimate varied from –0.00858 to 0.00634 with p-values ranging from 0.31 to 0.78. ICS Impulse®: Horizontal SCCs: The estimate and the p-value for the right lateral SCC and the left lateral SCC were 0.00159 (0.18) and 0.00071 (0.38) respectively. Vertical SCCs: The estimate varied from 0.00217 to 0.01357 with p-values ranging from 0.00 to 0.17. Based upon the averaged gain value from the individual SCC being tested, 148 tests before and 127 after manual data selection were considered pathological. CONCLUSION: None of the two v-HIT systems revealed any clinically important effects of manual data selection. However, 21 fewer tests were considered pathological after manual data selection.

The Relationship

In order to identify the country of growth of Sophora flavescens by chemical fingerprinting, extracts of plants grown in China and Japan were analyzed using direct analysis in real time mass spectrometry (DART)-MS. The peaks characteristic of each country of growth were statistically analyzed using a volcano plot to summarize the relationship between the p-values of a statistical test and the magnitude of the difference in the peak intensities of the samples in the groups. Peaks with a p value <0.05 in the t-test and a ≥2 absolute difference were defined as characteristic. Peaks characteristic of Chinese S. flavescens were found at m/z 439 and 440. In contrast, peaks characteristic of Japanese S. flavescens were found at m/z 313, 423, 437 and 441. The intensity of the selected peaks was similar in Japanese samples, whereas the m/z 439 peak had a significantly higher intensity than the other peaks in Chinese samples. Therefore, differences in selected peak patterns may allow identification of the country of growth of S. flavescens.

Longitudinal Method

The semi-longitudinal method was used to trace changes in the mental ages of 906 institutionalized mentally retarded subjects as a function of chronological age, and equations were fitted to the resulting growth curves. Sex differences proved to be relatively slight. The higher levels of retardation had a higher initial growth rate and a more pronounced decline at higher age levels than did the lower levels, but they did not have a longer growing season. In all but the last respect, the findings resembled those obtained by Fisher and Zeaman (1970).
