2023/05/03 VAMPIRES Zero Point Data
<p>VAMPIRES reduced data from 2023/05/03 Behind the NIR PyWFS tests on Subaru/SCExAO. These data have been reduced with the <a href="http://github.com/scexao-org/vampires_dpp">VAMPIRES DPP</a> and also serve as a zero point reference for "old" VAMPIRES. Note: most of this data is taken without the SCExAO Vis PyWFS, so the wavefront error is not as good as standard VAMPIRES observations.</p>

X-ray spectra of eFEDS point sources
<p>The X-ray spectra of point sources in the eFEDS catalog used in the paper "The eROSITA Final Equatorial-Depth Survey (eFEDS). The AGN catalog and its X-ray spectral properties" (Liu et al. 2022)</p><p>Webpage of the eFEDS AGN catalog: https://erosita.mpe.mpg.de/edr/eROSITAObservations/Catalogues/liuT/eFEDS_AGN_spec_V10.html</p><p>There are 27910 folders. Each one is named by the source ID and contains the spectra files of this source. Note that the files are large and will need 44G (part1) + 44G (part2) + 40G (part3) space.</p>
Machine learning based methods to generate conformational ensembles of disordered proteins (len18, point mutation)
<p>data is organized by bin number (0-9) and mutation location (4, 8, 12). (Note: in the manuscript, we used the nomenclature bins 1-10 and mutation locations 5,8,13. We simply used a 0-index convention when naming our folders). All data is in rep_1, which contains the trajectory (xtc) file, Rg information (in the file Rg.out), pairwise distance information (in the file traj_analysis_data/pairwise_distance_matrix.csv) and the bspline coefficients (in the file bspline_info/xyz_coeff.npy). However, for bin_num=9/mutation_loc=12, the data used is in rep_2, not rep_1. </p>
XFP-054-32-4 Sanak Point, Sanak Island, Alaska.
Sanak Point, Sanak Island, Alaska. CAT# XFP-054-32-4 (#6?) XFP-054 is an early village in a dune area on the south side of Sanak Island, Alaska. The dune is deflating, leaving behind dozens of well-preserved houses and site features. It clearly demonstrates the village organization of this time period between 2200 and 1600 BCE. This is the time of the early occupation of Hot Springs Village on the Alaska Peninsula. These artifacts were scanned with either a Faro Edge Arm or a Minolta Vivid 9i. Processed in Geomagic or Polyworks. 2-8 photos were used for texture in Geomagic Wrap. The Sanak Island artifacts are presented as a result of research conducted under grants NSF 0326584, NSF 0508101, NSF 1139266, NSF 1321411. H. Maschner, Principal Investigator. Original digitizing work done at the IVL at Id. St. Univ. Subsequent processing completed at Global Digital Heritage.

Possible LeCroy Projectile Point
A quartz LeCroy (possible) projectile point (7600-7350 B.C.) recovered during the archaeological investigation of several precontact period sites along the Patapsco River in Anne Arundel County, Maryland by Richard Stearns and the Natural History Society of Maryland in 1949. LeCroy points are small, thin, and often serrated, with a deeply bifurcated base.

Izembek Point XCB-003-481
Izembek Point XCB-003-481 XCB-003, or IZM-003, is a site tested by A.P. McCartney in 1971. It is the type-site for the Izembek Phase. A small village with a unique whalebone house and many artifacts similar to those in the Bristol Bay region. It dates approximately 1200-1350 CE. The Alaska Peninsula artifacts are presented as a result of the research conducted under grants NSF 9630072, NSF 9814086, NSF 9996372, NSF 9996415, NSF 1139266, NSF 1321411. H.
