Stellar chromospheric activity database of solar-like stars based on the Ca II H and K lines of LAMOST Low-Resolution Spectroscopic Survey: the bolometric and photospheric calibration
<p>This database contains the stellar chromospheric activity parameters of solar-like stars based on the Ca II H and K lines from the spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low-Resolution Spectroscopic Survey (LRS). We extract 1,122,495 LRS spectra of solar-like stars from the LAMOST Data Release 8 v2.0 and provide the chromospheric activity parameters $S_{\rm tri}$, $S_{\rm MWO}$, $R_{\rm HK}$ and $R'_{\rm HK}$, as well as their uncertainties in the database. $R_{\rm HK}$ and $R'_{\rm HK}$ are derived from the method in the classic literature (denoted with classic) and the method based on the PHOENIX model (denoted with PHOENIX). These stellar chromospheric activity indexes and their uncertainties, along with the relevant spectroscopic parameters from the LAMOST catalogs, are saved in a CSV-format file (name: CaIIHK_Activity_Indexes_LAMOST_DR8_LRS.csv).</p> <p> </p> <p>Columns in the catalog of the database:</p> <p>obsid - Unique observation identifier of LAMOST LRS spectrum</p> <p>obsdate-Spectral observation date</p> <p>fitsname - FITS file name of LAMOST LRS spectrum</p> <p>snrg - Signal-to-noise ratio in the $g$ band ($\mathrm{S/N}_g$) of LAMOST LRS spectrum</p> <p>snrr - Signal-to-noise ratio in the $r$ band ($\mathrm{S/N}_r$) of LAMOST LRS spectrum</p> <p>teff - Effective temperature ($T_\mathrm{eff}$) derived from the LASP (unit: K)</p> <p>teff_err - Uncertainty of $T_\mathrm{eff}$ derived from the LASP (unit: K)</p> <p>logg - Surface gravity ($\log\,g$) derived from the LASP (unit: dex)</p> <p>logg_err - Uncertainty of $\log\,g$ derived from the LASP (unit: dex)</p> <p>feh - Metallicity ([Fe/H]) derived from the LASP (unit: dex)</p> <p>feh_err - Uncertainty of [Fe/H] derived from the LASP (unit: dex)</p> <p>rv - Radial velocity ($V_r$) derived from the LASP (unit: km/s)</p> <p>rv_err - Uncertainty of $V_r$ derived from the LASP (unit: km/s)</p> <p>ra_obs - Right ascension (RA) of fiber pointing (unit: degree)</p> <p>dec_obs - Declination (DEC) of fiber pointing (unit: degree) </p> <p>gaia_source_id - Source identifier in Gaia DR3 catalog</p> <p>gaia_g_mean_mag - $G$ magnitude in Gaia DR3 catalog</p> <p>S_tri* - $S_{\rm tri}$ index of LAMOST LRS </p> <p>S_tri_err* - Uncertainty of $S_{\rm tri}$ </p> <p>S_MWO* - $S_{\rm MWO}$ </p> <p>S_MWO_err* - Uncertainty of $S_{\rm MWO}$ </p> <p>log_R_HK_classic* - $\log\,R_{\rm HK,classic}$ </p> <p>log_R_HK_classic_err* - Uncertainty of $\log\,R_{\rm HK,classic}$ </p> <p>log_R_p_HK_classic* - $\log\,R'_{\rm HK,classic}$ </p> <p>log_R_p_HK_classic_err* - Uncertainty of $\log\,R'_{\rm HK,classic}$ </p> <p>log_R_HK_PHOENIX* - $\log\,R_{\rm HK,PHOENIX}$ </p> <p>log_R_HK_PHOENIX_err* - Uncertainty of $\log\,R_{\rm HK,PHOENIX}$ </p> <p>log_R_p_HK_PHOENIX* - $\log\,R'_{\rm HK,PHOENIX}$ </p> <p>log_R_p_HK_PHOENIX_err* - Uncertainty of $\log\,R'_{\rm HK,PHOENIX}$ </p> <p>(Note: The columns denoted by an asterisk represent the parameters provided by this database, and the remaining columns are collected from the data release of LAMOST DR8 V2.0.

Wildfire, prescribed burn, and agricultural burn smoke PM2.5 estimates for CA, WA, and OR 2014-2020
<p>Wildfires, prescribed burns, and agricultural burns all impact ambient air quality across the Western U.S.; however, little is known about how communities across the region are differentially exposed to smoke from each of these fire types. To address this gap, we quantify smoke exposure stemming from wildfire, prescribed, and agricultural burns across Washington, Oregon, and California from 2014-2020 using a fire type-specific biomass burning emissions inventory and the GEOS-Chem chemical transport model. We examine fire type-specific PM<sub>2.5</sub> concentration by race/ethnicity, socioeconomic status, and in relation to the Center for Disease Control's Social Vulnerability Index. Overall, population average PM<sub>2.5</sub> concentrations are greater from wildfires than from prescribed and agricultural burns. While we found limited evidence of exposure disparities among sub-groups across the full study area, we did observe disproportionately higher exposures to wildfire-specific PM<sub>2.5</sub> exposures among Native communities in all three states and, in California, higher agricultural burn-specific PM<sub>2.5</sub> exposures among lower socioeconomic groups. We also identified, for all three states, areas of significant spatial clustering of smoke exposures from all fire types and increased social vulnerability. These results provide a first look at the differential contributions of smoke from wildfires, prescribed burns, and agricultural burns to PM<sub>2.5</sub> exposures among demographic subgroups, which can be used to inform more tailored exposure reduction strategies across sources.</p>

Devil's Slide Bunker - Pacifica, CA
And oldie but a goodie. Going through some archives and re-processing unpublished work. **Description** Devil's Slide was the location of a military triangulation station and observation site used during World War II as part of the harbor defense of San Francisco. Prior to the advent of radar, military personnel used binoculars and compasses to search for ships at sea and relay their coordinates to a central post. By combining information from multiple observation posts, a ship's precise location could be determined by triangulation. There were six military structures at the Devil's Slide: three concrete and steel observation pill-boxes, two concrete and earth bunkers, and a reinforced steel observation tower. The pill-boxes were used as hardened observation posts, and one of the bunkers was used as a communications and command post. - https://en.wikipedia.org/wiki/Devil%27s_Slide_(California) **Technical Notes:** For use with Unlit shader in Unity - [import instructions](http://azadux.com/import) Source: Objaverse 1.0 / Sketchfab
Marble grave stele with a family group ca. 360 B
Because the framing niche that once surrounded this relief is missing, there are no inscriptions that might identify the deceased. Both the seated man and the veiled woman behind him stare straight ahead, as if the young woman who gazes down at them were invisible. Do they mourn their dead daughter? Does she mourn her dead father, or is she the sole survivor of the group? Despite its ambiguity and solemn sadness, the relief conveys an intense, though restrained, sense of family unity. Carved by a master, this grave stele is one of the most magnificent examples that have survived from the classical period. From the Metropolitan Museum of Art Source: Objaverse 1.0 / Sketchfab

Contents, Format, and Reader Interactions with Middle English Practical Manuscripts, ca. 1375–1500
<p>These three .csv files contain datasets intended to supplement the book, <em><a href="https://press.uchicago.edu/ucp/books/book/chicago/R/bo222256991.html">Reading Practice: The Pursuit of Natural Knowledge from Manuscript to Print</a> </em>(University of Chicago Press, 2024). They convey information on 182 Middle English "practical" manuscripts created between ca. 1375 and 1500. Practical manuscripts are defined as manuscripts written entirely (or nearly so) in Middle English containing contents entirely (or nearly so) related to medicine and practical science, like agriculture, animal husbandry, and craft manufacture.</p> <p>To identify these 182 manuscripts, I first searched the Voigts-Kurtz database of <a href="https://cctr1.umkc.edu/search" target="_blank" rel="noopener"><em>Medical and Scientific Writings in Middle English</em></a>, compiled over several decades by Linda Ehrsam Voigts and Patricia Deery Kurtz and now containing data on more than 1200 manuscripts containing Middle English medical or scientific texts. After identifying promising manuscripts in the Voigts-Kurtz database, I followed this initial search with consultations of manuscript catalogues for the Beinecke Library, Yale University; Bodleian Library, University of Oxford; British Library, London; Cambridge University Library, Cambridge; Henry E. Huntington Library, San Marino, CA; Morgan Library, New York; National Library of Medicine, Bethesda, MD; Trinity College Cambridge Library, Cambridge; University of Glasgow Library, Glasgow; and Wellcome Library, London. In addition to identifying manuscripts not cited in the Voigts-Kurtz database, these catalogue searches enabled me to weed out manuscripts that contained too much Latin for my purposes or those that contained just a small section of medicine and science and were otherwise devoted to literature, law, religion, or other texts. <br><br>From these searches, I identified over 300 fifteenth-century manuscripts that I hoped would <br>reveal how English lay people thought of books as tools for collecting and utilizing knowledge<br>related to day-to-day medical practice, agriculture, or husbandry. However, I couldn't ascertain <br>if the manuscripts I had identified were the sort of book that a non-elite person might own<br>until I made research trips to the libraries and archives that held them. I was fortunate <br>to begin this project at the same time that many libraries in the U.K. were changing their <br>policies in regards to digital photography. As a result, I was able to photograph scores of <br>manuscripts in a single trip, which I then analyzed and catalogued in my database over the <br>following months. These research trips, conducted over summers and academic holidays between <br>2014 and 2021, enabled me to whittle down my initial corpus of over 300 potential "practical manuscripts" <br>to the 182 manuscripts analyzed in <em>Reading Practice</em> and described in these appendices. Part of this<br>process entailed identifying fifteenth-century manuscripts that had been bound into composite volumes<br>by later collectors. These once-separate manuscripts are counted individually in my corpus, and their <br>folio numbers in those composite volumes are noted in the spreadsheet below.</p> <p>The "Manuscript Attributes" .csv file contains the following information on each of these 182 vernacular manuscripts:</p> <ul> <li>Shelfmark</li> <li>Archive/library</li> <li>Approximate date of creation</li> <li>Writing support (paper or parchment)</li> <li>Number of folios (and folio numbers, for composite manuscripts)</li> <li>Size in mm</li> <li>Quality of scribal hand</li> <li>Information on contents</li> <li>Information on reader marks</li> <li>Information on reader cancellations or censorship</li> <li>URL for digital facsimile, if available</li> </ul> <p>The contents field of the "Manuscript Attributes" .csv file indicates whether the manuscript contains texts in the following genres, and which texts those are, if readily identifiable:</p> <ul> <li>Illustrations</li> <li>Medical recipes</li> <li>Herbals</li> <li>Charms</li> <li>Medical treatises</li> <li>Treatises on phlebotomy</li> <li>Reproductive recipes</li> <li>Uroscopy texts</li> <li>Surgical texts or surgical recipes</li> <li>Craft recipes</li> <li>Dietaries or health regimens</li> <li>Plague treatises</li> <li>Prognostications</li> <li>Texts on weights and measures</li> <li>Texts on animal husbandry</li> <li>Texts on planting, grafting, or gardening</li> <li>Texts on hawking, hunting, or fishing</li> <li>Almanacs</li> <li>Treatises on astrology</li> <li>Culinary recipes</li> </ul> <p>The "Reader Marks" .csv file contains transcriptions of every reader mark in a fifteenth-<br>century practical manuscript that I could attribute to a reader or which could be dated <br>definitively. In addition, the spreadsheet contains notes about other reader and scribal additions,<br>like added recipes or indices. I note the location of these marks and indicate<br>whether they were made in the fifteenth (XV), sixteenth (XVI), or seventeenth (XVII)<br>centuries. In total, the spreadsheet contains notes or transcriptions of over 500 separate<br>instances of reader interactions with practical manuscripts.</p> <p>The "Cancellations" .csv file contains information about which manuscripts feature censorship of any kind and what sorts of material was censored or cancelled.</p>
