Intermuscular Coherence in Normal Adults: Variability and Changes with Age
<p><strong>Dataset underlying the paper "Intermuscular Coherence in Normal Adults: Variability and Changes with Age", published in PLOS ONE.</strong></p> <p><strong>Abstract: </strong>We investigated beta-band intermuscular coherence (IMC) in 92 healthy adults stratified by decade of age, and analysed variability between and within subjects. In the dominant upper limb, IMC was estimated between extensor digitorum communis and first dorsal interosseous as well as between flexor digitorum superficialis and first dorsal interosseous. In the ipsilateral lower limb, IMC was measured between medial gastrocnemius and extensor digitorum brevis as well as between tibialis anterior and extensor digitorum brevis. Age-related changes in IMC were analysed with age as a continuous variable or binned by decade. Intrasession variance of IMC was examined by dividing sessions into pairs of epochs and comparing coherence estimates between these pairs. Eight volunteers returned for a further session after one year, allowing us to compare intrasession and intersession variance. We found no age-related changes in IMC amplitude across almost six decades of age, allowing us to collate data from all ages into an aggregate normative dataset. Interindividual variability ranged over two orders of magnitude. Intrasession variance was significantly greater than expected from statistical variability alone, and intersession variance was even larger. Potential contributors include fluctuations in task performance, differences in electrode montage and short-term random variation in central coupling. These factors require further exploration and, where possible, minimisation. This study provides evidence that coherence is remarkably robust to senescent changes in the nervous system and provides a large normative dataset for future applications of IMC as a biomarker in disease states.</p>
Urban area age and coefficient of variation of spatial area extent
<p>The dataset contains an proxy for the age of urban area and the coefficient of variation of its spatial extent as proxy for spatial dynamics. Both variables are studied as key to conceptualize the process of urbanization by means of clusters of local spatial autocorrelation. The analysis is based on the HYDE 3.1 database, cf. Klein Goldewijk et al. (2010), Klein Goldewijk et al. (2011).</p>

Education- and age-specific fertility rates for 50 African and Latin American countries between 1970 and 2020

In this paper, we propose a Bayesian framework to reconstruct age-specific fertility rates by level of education using prior information from the birth history module of the Demographic and Health Surveys (DHS) and the UN World Population Prospects. In our case study regions, we reconstruct age- and education-specific fertility rates which are consistent with the UN age specific fertility rates by four levels of education for 50 African and Latin American countries from 1970 to 2020 in five-year steps. Our results show that the Bayesian approach allows for estimating reliable education- and age-specific fertility rates using multiple rounds of the DHS surveys. The time series obtained confirm the main findings of the literature on fertility trends, and age and education specific differentials.</p> <p><strong>Funding:</strong></p> <p>These data sets are part of the <a href="https://www.oeaw.ac.at/vid/research/research-projects/bayesedu">BayesEdu Project </a>at Wittgenstein Centre for Demography and Global Human Capital (IIASA, OeAW, University of Vienna) funded from the “Innovation Fund Research, Science and Society” by the Austrian Academy of Sciences (ÖAW).</p> <p><strong>Variables:</strong></p> <p>Country: Country names</p> <p>Education: Four education levels, No Education, Primary Education, Secondary Education and Higher Education.</p> <p>Age group: Five-year age groups between 15-19 and 45-49. </p> <p>Year: Five-year periods between 1970 and 2020.</p> <p>Median: Median education and age-specific fertility rate estimate </p> <p>Upper_CI: 95% Upper Credible Interval</p> <p>Lower_CI: 95% Lower Credible Interval</p> <p> </p> <p><strong>List of countries:</strong></p> <table> <tbody> <tr> <td> <p>Angola</p> </td> </tr> <tr> <td> <p>Benin</p> </td> </tr> <tr> <td> <p>Brazil</p> </td> </tr> <tr> <td> <p>Burkina Faso</p> </td> </tr> <tr> <td> <p>Burundi</p> </td> </tr> <tr> <td> <p>Cameroon</p> </td> </tr> <tr> <td> <p>Central African Republic</p> </td> </tr> <tr> <td> <p>Chad</p> </td> </tr> <tr> <td> <p>Colombia</p> </td> </tr> <tr> <td> <p>Comoros</p> </td> </tr> <tr> <td> <p>Congo</p> </td> </tr> <tr> <td> <p>Côte D'Ivoire</p> </td> </tr> <tr> <td> <p>DR Congo</p> </td> </tr> <tr> <td> <p>Ecuador</p> </td> </tr> <tr> <td> <p>Egypt</p> </td> </tr> <tr> <td> <p>Eswatini</p> </td> </tr> <tr> <td> <p>Ethiopia</p> </td> </tr> <tr> <td> <p>Gabon</p> </td> </tr> <tr> <td> <p>Gambia</p> </td> </tr> <tr> <td> <p>Ghana</p> </td> </tr> <tr> <td> <p>Guatemala</p> </td> </tr> <tr> <td> <p>Guinea</p> </td> </tr> <tr> <td> <p>Honduras</p> </td> </tr> <tr> <td> <p>Kenya</p> </td> </tr> <tr> <td> <p>Lesotho</p> </td> </tr> <tr> <td> <p>Liberia</p> </td> </tr> <tr> <td> <p>Madagascar</p> </td> </tr> <tr> <td> <p>Malawi</p> </td> </tr> <tr> <td> <p>Mali</p> </td> </tr> <tr> <td> <p>Mexico</p> </td> </tr> <tr> <td> <p>Morocco</p> </td> </tr> <tr> <td> <p>Mozambique</p> </td> </tr> <tr> <td> <p>Namibia</p> </td> </tr> <tr> <td> <p>Nicaragua</p> </td> </tr> <tr> <td> <p>Niger</p> </td> </tr> <tr> <td> <p>Nigeria</p> </td> </tr> <tr> <td> <p>Paraguay</p> </td> </tr> <tr> <td> <p>Peru</p> </td> </tr> <tr> <td> <p>Rwanda</p> </td> </tr> <tr> <td> <p>Sao Tome and Principe</p> </td> </tr> <tr> <td> <p>Senegal</p> </td> </tr> <tr> <td> <p>Sierra Leone</p> </td> </tr> <tr> <td> <p>South Africa</p> </td> </tr> <tr> <td> <p>Sudan</p> </td> </tr> <tr> <td> <p>Tanzania</p> </td> </tr> <tr> <td> <p>Togo</p> </td> </tr> <tr> <td> <p>Tunisia</p> </td> </tr> <tr> <td> <p>Uganda</p> </td> </tr> <tr> <td> <p>Zambia</p> </td> </tr> <tr> <td> <p>Zimbabwe</p> </td> </tr> </tbody> </table>
Data from: Social networks reveal sex- and age-patterned social structure in Butler's Gartersnakes
<p>Sex- and age-based social structures have been well-documented in animals with visible aggregations. However, very little is known about the social structures of snakes. This is most likely because snakes are often considered non-social animals and are particularly difficult to observe in the wild. Here, we show that wild Butler's Gartersnakes have an age and sex assorted social structure similar to more commonly studied social animals. To demonstrate this, we use data from a 12-year capture-mark-recapture study to identify social interactions using social network analyses. We find that the social structures of Butler's Gartersnakes comprise sex- and age-assorted intra-species communities with older females often central and age segregation partially due to patterns of study site use. In addition, we find that females tended to increase in sociability as they aged while the opposite occurred in males. We also present evidence that social interaction may provide fitness benefits, where snakes that were part of a social network were more likely to have improved body condition. We demonstrate that conventional capture data can reveal valuable information on social structures in cryptic species. This is particularly valuable as research has consistently demonstrated that understanding social structure is important for conservation efforts. Additionally, research on the social patterns of animals without obvious social groups provides valuable insight into the evolution of group living.</p>
Gender and age-related differences of ccular biometric parameters in patients undergoing cataract surgery in Bosnia and Herzegovina
<p><strong>Purpose</strong>: To determine the distribution and mutual relationship of ocular biometric parameters, as well as to evaluate gender- and age-related differences in patients undergoing cataract surgery in Bosnia and Herzegovina.</p> <p><strong>Materials and methods</strong>: It was a retrospective cross-sectional study of consecutive patients who underwent cataract surgery between January 2017 and December 2021 in a tertiary care clinic. All biometric measurements were performed using the optical biometer OA-2000 (Tomey, Nagoya, Japan).</p> <p><strong>Results</strong>: The study evaluated 1278 eyes from 1278 consecutive cataract patients. The average age of all included patients was 69.4 ± 9.98 (range 40–96). A total of 672 eyes (52.58%) were from females. The mean axial length (AL), anterior chamber depth (ACD), lens thickness (LT), and mean keratometry were 23.46±1.18mm, 3.17±0.40mm, 4.54±0.48mm, 43.42±1.55D respectively. Corneal astigmatism of ≥1D, >2D and >3D was found in 33.4%, 7.8% and 2.5% patients, respectively. Females were found to have shorter AL (p<0.0001), shallower ACD (p<0.0001) and steeper corneas (p<0.0001). In both genders, AL, ACD and with-the-rule astigmatism showed a decreasing trend (p=0.0001), while keratometry, the average cylinder, and against-the-rule astigmatism showed an increasing trend (p=0.0001) with increasing age. Furthermore, in both genders, there was an increasing trend in ACD (p=0.0001), and a decreasing trend in keratometry (p=0.0001) and LT (p=0.0001) with increasing AL.</p> <p><strong>Conclusions</strong>: This study provides useful reference data on ocular biometry for cataract surgeons in Bosnia and Herzegovina. Female patients tend to have steeper corneas, shorter AL and shallower AC than males, and these differences are independent of age or AL.</p>
HOLOCENE OVERWASH OCCURRENCE AGE IN THE ISUMI RIVER LOWLAND, EASTERN BOSO PENINSULA, JAPAN
<p>Analysis of the chronological data and observation of a lagoonal sediment core reveal sand washover events between around 2.4 to 2.5 cal. ky BP in the Isumi River lowland. We conducted radiocarbon dating with AMS and constructed an age-depth model using the latest calibration curve and appropriate model routine. In the middle to lower part of the core, dark-gray sand layers are repeatedly deposited. Sand layers may exhibit an erosional surface at the base with fining upward grading. The overwash layers are composed of well-rounded sand with occasional gravel, indicative of transportation. overwash sediment characteristics are consistent with proximal marine deposits, suggesting an ocean origin (though riverine sediment is also similar in character). The age-depth model indicates very high sediment accumulation rates associated with overwash deposits. Based on the amount of accumulated sediment, relatively large scale redeposition events occurred during this period but more information is needed to constrain the mechanism(s) causing the events. We also present a local reservoir age correction compatible with the Marine20 calibration curve.</p>

Faunal remains data from Paleolithic to early Iron Age archaeological sites in the Qinghai-Tibet Plateau in China
<p>According to published archaeological sources, zooarchaeological data collection on the Qinghai-Tibet Plateau and its marginal and transitional areas is inadequate, and relevant datasets have not been published. For this reason, we collected and collated relevant information. Our database provides the geographical location, elevation, cultural type and faunal assemblage of each site on the Qinghai-Tibet Plateau and its periphery for which zooarchaeological data have been published from the Paleolithic to the Early Iron Age. The patterns of human faunal resource use, habitat patterns, and animal abundance and spatial distribution on the Qinghai-Tibet Plateau and its surrounding areas during the Prehistoric-Early Iron Age are represented in this dataset. The data provide a reference for further understanding prehistoric-early Iron Age human behavior, subsistence patterns and material and cultural exchanges between East and West on the Qinghai-Tibet Plateau and its environs.</p>
