Is the lunar magnetic field correlated with gravity or topography?
<p>Supplementary data to the article</p> <p> Gong, S. and Wieczorek, M. (2020) Is the lunar magnetic field correlated<br> with gravity or topography? Journal of Geophysical Research: Planets.</p> <p>This archive contains the Bouguer gravity model used in the analyses of the<br> above cited manuscript, as well as the data files to reproduce Figures 2-3 and<br> Figures S1-S3. For the correlation results, the bandwidth and angular radius of<br> the window were 26 and 10 degrees, respectively, which yields a concentration<br> factor that is better than 99%.</p> <p><br> FILE DESCRIPTIONS</p> <p>34_12_3220_900_80_misfit.sh</p> <p> This file contains the spherical harmonic coefficients of the Bouguer<br> gravity model up to degree and order 900. The two values in the first<br> row correspond to the reference radius of the model in km and the<br> constant GM in km^3/s^-2. To generate this model, all known gravitational<br> contributions from the crust were removed from the free-air gravity,<br> including surface relief, lateral variations in crustal density, and<br> crustal thickness variations. The crustal thickness model is from<br> Wieczorek et al. (2013), which has an average thickness of 34 km, a<br> constant crustal porosity of 12%, and a mantle density of 3200 kg/m^3.</p> <p><br> mc_total_10_26_1_surface.dat</p> <p> Data used to generate the lower panel of Figure 2. This file contains the<br> 95% confidence limits of the average correlation from the Monte Carlo<br> simulations which were performed every 30 degrees in both longitude and<br> latitude. The first two columns correspond to the latitude and longitude,<br> and the third to fifth columns correspond to the 95% confidence limits by<br> using topography, total free-air gravity, and total Bouger gravity,<br> respectively.</p> <p><br> spec_10_26_1_surface.dat</p> <p> Data used to generate Figure 3. Correlation results between total magnetic<br> field and topography, total free-air gravity, and total Bouguer gravity at<br> the surface. The first two columns correspond to the latitude and longitude,<br> and the third to fifth columns correspond to the ratio between the average<br> correlation and its 95% confidence limits by using topography, total<br> free-air gravity, and total Bouger gravity, respectively. If the value is<br> equal to or greater than 1, this indicates that the total magnetic field is<br> positively correlated with the testing field (topography, total free-air<br> gravity, or total Bouguer gravity); If the value is equal to or less than<br> -1, this indicates that the total magnetic field is negatively correlated<br> with the testing field.</p> <p><br> spec_10_26_1_surface_4lwin.dat</p> <p> Data used to generate Figure S1.

Daily cross-correlation functions for "Time-lapse monitoring of seismic velocity associated with 2011 Shinmoe-dake eruption using seismic interferometry: an extended Kalman filter approach"
<p>The daily cross-correlation functions used in Nishida et al. 2020. We used three-component seismograms recorded at eight stations (six broadband sensors and two short-period sensors with a natural frequency of 1 Hz) from May 1st, 2010 to April 30th, 2018. Five stations were deployed by the Earthquake Research Institute, the University of Tokyo, and the other three were deployed by the National Research Institute for Earth Science and Disaster Prevention (NIED). The data can be found in the HDF5 file. You can also find a python code of an implementation of an extended Kalman filter/smoother for time-lapse monitoring of seismic velocity at GitHub (https://github.com/qnishida/eKlfS). The code estimates the temporal change in seismic velocities using this data set. </p>
Data from: Cognitive correlates of cerebellar resting-state functional connectivity in Parkinson disease.
Objective: The purpose of this cross-sectional study was to investigate the contributions of altered cerebellar resting-state functional connectivity (FC) to cognitive impairment in Parkinson disease (PD). Methods: We conducted morphometric and resting-state functional connectivity MRI (FC-MRI) analyses contrasting 81 PD and 43 age-matched healthy controls using rigorous quality assurance measures. To investigate the relationship of cerebellar FC to cognitive status, we compared PD participants without cognitive impairment (Clinical Dementia Rating scale, CDR=0; n=47) to PD participants with impaired cognition (CDR≥0.5; n=34). Comprehensive measures of cognition across the five cognitive domains were assessed for behavioral correlations. Results: The PD participants had significantly weaker FC between the vermis and peristriate visual association cortex compared to controls, and the strength of this FC correlated with visuospatial function and global cognition. In contrast, weaker FC between vermis and dorsolateral prefrontal cortex was found in the cognitively impaired PD group compared to PD participants without cognitive impairment. This effect correlated with deficits in attention, executive functions and global cognition. No group differences in cerebellar lobular volumes or regional cortical thickness of the significant cortical clusters were observed. Conclusion: These results demonstrate a correlation between cerebellar vermal FC and cognitive impairment in PD. The absence of significant atrophy in cerebellum or relevant cortical areas suggests this could be related to local pathophysiology such as neurotransmitter dysfunction.
Serum 25(OH)D level on hospital admission is correlated with COVID-19 mortality
<p>Objective: Vitamin D deficiency was previously correlated with incidence and severity of COVID-19. We investigated the correlation between serum 25(OH)D level on admission and radiological stage and outcome of COVID-19 pneumonia. </p> <p>Methods: Retrospective observational trial on 186 SARS-CoV-2-infected individuals hospitalized from March 1, 2020 to April 7, 2020 with combined chest CT and 25(OH)D measurement on admission. Multivariate analysis was performed to study if vitamin D deficiency (25(OH)D < 20 ng/mL) predicts survival independently of confounding comorbidities. </p> <p>Results: 59% of COVID-19 patients were vitamin D deficient on admission: 47% of females and 67% of males. Particularly male COVID-19 patients showed progressively lower 25(OH)D with advancing radiological stage, with deficiency rates increasing from 55% in stage 1 to 74% in stage 3. Vitamin D deficiency on admission was not confounded by age, chronic lung disease, coronary artery disease/hypertension or diabetes and was correlated with mortality (OR=3.87, 95%CI 1.30-11.55), independently of other predictors including age (OR=1.09, 95%CI 1.03-1.14), chronic lung disease (OR=3.61, 95% CI 1.18-11.09) and extent of lung damage expressed by chest CT severity score (1.12, 95% CI 1.01-1.25). </p> <p>Conclusions: low 25(OH)D levels on admission are associated with COVID-19 disease mortality</p>

Data from: Negative correlation between dispersal investment and canopy openness among populations of the ant-dispersed sedge, Carex lanceolata
<p><span><span><span><span><span><span><span><span><span><span>Flowering plants</span></span></span></span></span></span></span></span></span></span><span><span><span><span><span><span><span><span><span><span><span> exhibit a wide variation in the resources they invest in dispersal structures (dispersal effort), but the environmental correlates remain unclear in many plants. Canopy openness is predicted to be negatively correlated with dispersal effort, because selective pressures on increased dispersal effort, including host-specific natural enemies and the paucity and/or ephemerality of safe sites, will be more prevalent in shady sites. Here, we tested this prediction using an ant-dispersed sedge, <i>Carex lanceolata</i> (Cyperaceae). By comparing seven populations of <i>C</i>.<i> lanceolata</i> in central Japan, we found a negative correlation between dispersal effort and canopy openness, thus supporting the prediction. A subsequent cafeteria experiment showed that a large species of ant (<i>Formica japonica</i>) with relatively long seed-dispersal distances tended to prefer diaspores with greater dispersal efforts, while smaller ant species with shorter dispersal distances preferred diaspores with lower dispersal efforts. These results correspond with the assumption that greater dispersal efforts result in a greater dispersal ability and indicate that among-site variations in dispersal efforts actually reflect differentiation in seed dispersal strategy rather than a neutral variation. There were more signs of rust infection caused by <i>Puccinia</i> spp., one of the main natural enemies of <i>C</i>.<i> lanceolata</i>, on adult plant leaves in more shady sites. A seedling transplant experiment was also performed and revealed that rust severity in sedge offspring was considerably reduced by the typical seed dispersal distance (ca. 4 m) afforded by the large ant species, <i>F</i>.<i> japonica</i>. The increased rust severity at shady sites, combined with the narrow dispersal ranges of rusts, can partially explain the negative correlation of dispersal effort with canopy openness. These results support the importance of canopy openness as a factor underlying the variations in dispersal effort seen among flowering plants.</span></span></span></span></span></span></span></span></span></span></span></p>
Size-dependent male mating tactics and their morphological correlates in Poecilia gillii
<p>Male alternative reproductive strategies are found in some species of most major animal taxa, but are especially widespread in fishes. Mature males of the shortfin molly, <i>Poecilia gillii</i>, display extensive variation in size and morphology. We devised a field test of <i>a priori</i> hypotheses regarding the interrelationships between male size, colouration, morphology, and mating tactics. Males did not occur in discrete size classes, but instead occurred in a size and morphological continuum. Large males exhibited darker and more orange coloured dorsal and caudal fins, while small males exhibited lighter and more inconspicuous fin colouration. Furthermore, larger males had proportionately deeper bodies, larger dorsal and caudal fins, and shorter gonopodia than smaller males. <span>Our field study of male mating behaviour revealed a lack of courtship in this species, and similar levels of mating attempts (gonopodial thrusts) irrespective of male size. Instead, small males were significantly more likely to chase females than were large males. In contrast, large males exhibited higher rates of gonoporal nibbling (</span>a likely means by which males determine, through chemical factors, whether a female is carrying fertilizable ova)<span> and higher likelihood of chasing other</span> males away. In total, we found evidence for the predicted associations between male size, colouration, morphology and mating behaviour – associations that appear likely to maximize mating success for males of a given body size and phenotype.</p>
