Dataset for Quaternary Complex Hadamard Matrices of Order 18
<p>The files contain the quaternary complex Hadamard matrices of order 18 classified in the work "Patric R. J. Östergård and William T. Paavola, Quaternary Complex Hadamard Matrices of Order 18".</p> <p>Each file bh18-t<strong>n</strong>.txt contains the matrices of type <strong>n</strong> up to Hadamard equivalence. Each matrix is expressed as a human-readable 18 by 18 array of <strong>x</strong>∈{0,1,2,3} such that the corresponding elements of each matrix are given by raising the imaginary unit to the power of <strong>x</strong>. Each array is followed by a single row that contains the size of the stabilizer of the matrix.</p>

Fig. 20 in Quaternary Murid Rodents Of Timor Part I: New Material Of Coryphomys Buehleri Schaub, 1937, And Description Of A Second Species Of The Genus
Fig. 20. Hypothesis of phylogenetic relationships among the major lineages of Murinae, based on the findings of recent molecular studies of multiple mitochondrial and nuclear genes (Michaux et al. 2001; Lecompte et al., 2002a, 2008; Jansa and Weksler, 2004; Jansa et al., 2006; Steppan et al., 2004; Rowe et al., 2008). Branch lengths are scaled according to the chronogram presented by Lecompte et al. (2008: fig. 2). The placement of Chiropodomys and Vandeleuria on this topology is based on the multigene phylogeny published by Rowe et al. (2008); branch lengths for these placements are approximate. The taxonomic content of each Tribe is summarized in table 3.

Data from: Ambient noise tomography of upper crustal structures and Quaternary faults in the Seoul metropolitan area and its geological implications
<p class="0"><span><span><span>We investigate the upper-crustal seismic velocity structure in the Seoul metropolitan</span> <span>area, where about 20 million people live. The Chugaryeong fault zone (CFZ) is</span> <span>placed in this area, but the seismic hazard potential remains unclear. We conducted</span> <span>ambient noise tomography to illuminate the high-resolution upper-crustal structure</span> <span>in the Seoul metropolitan area. We analyzed continuous vertical seismic records</span> <span>for ~5 months from a dense seismic array with 77 broadband stations. Group</span> <span>velocity dispersion curves and tomographic maps were extracted between 0.5 and 10</span> <span>s periods. We inverted 3-D group velocity tomography models up to a depth of ~10</span> <span>km from the group velocity maps. The shear-wave velocity model is consistent with</span> <span>the geological features. High-velocity anomalies at shallow depths are correlated</span> <span>with the surface topography and geology. The CFZ is located at a low velocity below the 5 km depth and presented as the simplified model. The large </span><span>V</span><span><sub>S</sub> </span><span>contrast</span> <span>regions are located beneath NS-trending faults. The cross-sections coincide with</span> <span>the near-vertical strike-slip faults in this area. In the southern region of the Seoul</span> <span>metropolitan area, low-velocity anomalies correlate with high heat flow regions. Our</span> <span>results effectively suggest high resolution upper-crustal structures and subsurface</span> <span>hidden faults in the urban area.</span></span></span></p>
