Dataset for Global Reference Seismological Data Sets: Multimode Surface Wave Dispersion
<ul> <li><strong>How fast do surface waves travel globally after any earthquake?</strong></li> <li><strong>Do we get the same information from various measurement techniques?</strong></li> <li><strong>Which features in the Earth are robust and can be resolved by a reference model?</strong></li> </ul> <p>Reference data with uncertainties are useful for improving existing measurement techniques, validating models of interior structure, calculating teleseismic data corrections in local or multiscale investigations and developing a 3-D reference Earth model. This study was done in collaboration with 18 scientists from 16 institutions in 7 countries who actively participated in the <a href="http://rem3d.org">REM3D</a> project. The project assimilated, archived, reconciled and modeled big (>200 million measurements) and diverse <a href="https://globalseismology.princeton.edu/data/surface-waves">surface-wave datasets</a> for global subsurface structure.</p> <p>The reference data set summarizes measurements of dispersion of fundamental-mode surface waves and up to six overtone branches from 44,871 earthquakes recorded on 12,222 globally distributed seismographic stations. Dispersion curves are specified at a set of reference periods between 25 and 250 s to determine propagation-phase anomalies with respect to a reference Earth model. Empirically determined observational uncertainties (1 sigma) for each wave type, branch number and period can be found in Table 3. </p> <p><strong>Summary:</strong></p> <p><strong>[I]</strong> <strong>Reconciled large and diverse catalogues</strong> of Love-wave (49.65 million) and Rayleigh-wave dispersion (177.66 million) from eight groups worldwide.<br> <strong>[II]</strong> Retrieved missing station and earthquake <strong>metadata</strong> in several legacy compilations and codified <strong>scalable formats</strong> to facilitate reproducibility, easy storage and fast I/O on HPC systems.<br> <strong>[III]</strong> <strong>Systematic discrepancies </strong>between raw phase anomalies can be attributed to discrepant theoretical approximations, reference Earth models and processing schemes.<br> <strong>[IV]</strong> <strong>Phase-velocity variations</strong> yielded by the inversion of the summary data set are <strong>highly correlated</strong> (R ≥ 0.8) with those from the quality-controlled contributing data sets, especially for long-wavelength variations (up to degree ∼25) in fundamental-mode dispersion (50–100 s).<br> <strong>[IV]</strong> <strong>Only 2ζ azimuthal variations</strong> in phase velocity of <strong>fundamental-mode Rayleigh waves</strong> are <strong>required</strong>; maps of 2ζ azimuthal variations are highly consistent between catalogues ( R = 0.6–0.8).</p> <p><strong>Feedback/Questions?</strong> Please contact Raj Moulik (<a href="https://rajmoulik.com">rajmoulik.com</a>) at <a href="mailto:moulik@caa.columbia.edu?subject=Query%20from%20Zenodo">moulik@caa.columbia.edu</a> </p> <p><strong>Reference:</strong></p> <p><em>Please cite the following work if you use this data or software.</em></p> <ul> <li>Moulik, P. <em>et al., </em>(2022) Global reference seismological data sets: multimode surface wave dispersion. <em>Geophys J Int</em> <strong>228</strong>, 1808–1849, doi: <a href="https://doi.org/10.1093/gji/ggab418">10.1093/gji/ggab418</a>. <em><a href="https://rajmoulik.com/Publications/Moulik_Reference_Surface_Waves_GJI2022.pdf">pdf</a></em></li> </ul> <p><em>You can also cite the dataset and software from this Zenodo page (Optional).</em></p> <ul> <li> <p>Moulik, P.

These files store the data in the RSDF HDF5 container format. These can be read using standard HDF5 modules (e.g. h5py) or using <a href="http://avni.globalseismology.org/">AVNI</a>. For example, to read the reference data for fundamental mode R1 waves at 100s into a Pandas Dataframe containing data (df['data']) and a dictionary with the metadata (df['metadata']), and thereafter write contents to an ASCII text file, enter the following in Python:</p> <ul> <li><em>from avni.data.SW import readSWhdf5,writeSWascii</em></li> <li><em>df=readSWhdf5(query='0/100.0/R1/REM3D',hdffile='Summary.SW.Rayl.data.h5',datatype='summary')</em></li> <li><em>writeSWascii(df,'test.txt')</em></li> </ul> <p><strong>ASCII (text) Format</strong></p> <p>These files contain the same reference data as the HDF5 files above but in gzipped ASCII files.

Universal potentials and corresponding data sets for metal clusters
<p>These potentials (*.pb) have been constructed using the data sets including the boxes, structural coordinates, energies and atomic forces of metal clusters, where the data sets have been generated using the concurrent learning workflow. For each metal cluster system, including pure metal clusters and alloys, the sample ensemble is maintained under NVT conditions with a temperature range spanning from approximately 50.0K to 1500 K. The system sizes encompass a range from small clusters to surfaces and bulk structures, which are subjected to periodic boundary conditions. In the case of alloys, the explorations are conducted throughout the entire concentration space, with each species varying in composition from 0 to 1.</p> <p>This dataset is maintained in AI2DB, you can access it via https://ai2db.ikkem.com/dynacat</p>

SNP data set of the Peruvian Creole cattle from southern Peru
<p>The Peruvian creole cattle (PCC) was originated after the introduction of cattle into the American continent about five centuries ago, and is an important source of power for agriculture, meat, and milk in the Peruvian highlands, as well as part of cultural traditions. However, little is known about the genetics of the PCC. In order to determine the genetic diversity and structure of the PCC, 69 DNA samples from four southern regions of Peru (Apurimac, Ayacucho, Cusco and Puno) were genotyped using a 100K SNP bead chip. After quality control and LD pruning, 24,200 SNPs were retained for further analysis. Animals were grouped into two clusters (C1: Apurimac, Ayacucho and Cusco, C2: Puno) using principal component analysis and UPGMA dendrogram. STRUCTURE analysis showed that individuals from Puno grouped in one cluster. Expected heterozygosity ranged from 0.399 (Apurimac) to 0.418 (Ayacucho). Negative inbreeding coefficient (F<sub>IS</sub>) values for PCC from Puno and Ayacucho were also found, possibly due to admixture. The lowest F<sub>ST</sub> (0.005) was estimated for Ayacucho and Cusco cattle populations, and the highest F<sub>ST</sub> (0.028) was reported for Puno and Apurimac cattle population. Small genetic variation among populations (3.65%) but higher variation within populations was found using AMOVA. To the best of our knowledge, this is the first study employing SNP markers in PCC, and as such it is hoped that this helps to pave the way towards its genetic improvement and the urgent sustainable management of creole animals in Peru.</p>
MarTREC Data Set for Report: Developing and Applying an Analysis Methodology to Identify Flow Generation Influences between Vessel and Truck Shipments
<p>Truck activity is logically connected to vessel activity at a port. In turn, vessel activity is also influenced by truck shipments. Although one might expect a direct and straightforward relation between these two types of shipments, that is rarely the case. For instance, many maritime containers carry consolidated cargos that have multiple and different final destinations. Also, different truck capacities, customs clearance and regulations play a critical role in determining the actual relation between these two types of shipments. This project aims at shedding light on the nuances of maritime and roadway flow relations by quantitatively analyzing the linkages between these two types of shipments.</p> <p>The study performed a statistical analysis to determine the probability distributions of vessel and truck activity, and then explore the correlation of each activity with the other. The analysis yielded coefficients that function as explanatory values for specific truck flows.</p> <p>The ultimate purpose of this study is to provide a clearer and quantitative understanding of the relationship between maritime and truck shipments, and by doing so, to provide tools to develop a system for managing trucks that maximizes efficiency for industry, while minimizing industry’s negative impacts on a region.</p> <p>For this purpose, the study selected the Port Freeport as a case study.</p>
