Proposal for three Greek papyrological charactersÂ
This is a proposal to add three Greek characters to the international character encoding standard Unicode, needed to represent text on papyri. The characters were published in Unicode Standard version 7.0 in June 2014
Ion-Abrasion Scanning Electron Microscopy Reveals Surface-Connected Tubular Conduits in HIV-Infected Macrophages
HIV-1-containing internal compartments are readily detected in images of thin sections from infected cells using conventional transmission electron microscopy, but the origin, connectivity, and 3D distribution of these compartments has remained controversial. Here, we report the 3D distribution of viruses in HIV-1-infected primary human macrophages using cryo-electron tomography and ion-abrasion scanning electron microscopy (IA-SEM), a recently developed approach for nanoscale 3D imaging of whole cells. Using IA-SEM, we show the presence of an extensive network of HIV-1-containing tubular compartments in infected macrophages, with diameters of ∼150–200 nm, and lengths of up to ∼5 µm that extend to the cell surface from vesicular compartments that contain assembling HIV-1 virions. These types of surface-connected tubular compartments are not observed in T cells infected with the 29/31 KE Gag-matrix mutant where the virus is targeted to multi-vesicular bodies and released into the extracellular medium. IA-SEM imaging also allows visualization of large sheet-like structures that extend outward from the surfaces of macrophages, which may bend and fold back to allow continual creation of viral compartments and virion-lined channels. This potential mechanism for efficient virus trafficking between the cell surface and interior may represent a subversion of pre-existing vesicular machinery for antigen capture, processing, sequestration, and presentation
Actors on High: The Skene Roof, the Crane, and the Gods in Attic Drama
Postprint of article "Actors on High: The Skene Roof, the Crane, and the Gods in Attic Drama" published in Classical Antiquity, volume 9, October 1990, pages 247-94, copyright 1990 by the Regents of the University of California.Discussion of the probable form of the roof as acting space in the fifth-century Theater of Dionysos in Athens, arguing for flat roof with no regular second story or superstructure above the one-story skene building; means of access to the roof by ladder or trapdoor or the theater crane; use of roof as acting space for human characters, gods, and ghosts; significance of spatial separation of human characters and divine characters and of the distinctiveness of divine locomotion. Appendix 1 lists uses of roof and crane and testimonia about the crane. Appendix 2 argues that crane had the form of a pivoted counterweighted beam (or shadouf) and offers speculation about its dimensions and operations

Digitized Images of the Lost Servius Manuscript Metz 292 (revised)
This document explains the set of images of a manuscript destroyed in WW II that have been placed in open access on Shared Shelf Comments. A group of 175 images was made available in early 2016. In May 2018, 106 additional images were made available, and this revised version of the document takes account of the additions and provides other updates to the documentation

August W. Schlegel, Comparaison entre la Phèdre de Racine et celle d'Euripide: a digital edition
August W. Schlegel published his essay "Comparaison entre la Phèdre de Racine et celle d'Euripide" in Paris in 1807 and included a very slightly revised version in his Essais littéraires et historiques in 1842, but these publications are not widely available and are not included in German editions of Schlegel's works. The "Comparaison" makes detailed comments on Jean Racine's Phèdre of 1677 and Euripides' Hippolytus of 428 BCE (Racine's major source, although he also drew on Seneca's Phaedra and other classical sources), and is an interesting document in the reception of Euripides and of Racine as well as useful evidence of the development of tragic theory in the German neoclassical and romantic traditions.This digital edition presents the text of the 1842 edition (with critical notes recording the variants of the 1807 version) with introduction, glossary of proper names, and annotations (many identifying quotations and allusions made by Schlegel without bibliographic reference), as well as some paragraphs from the preface to the 1842 book that comment on the circumstances of original publication.A subsequent version or versions of this digital edition will contain a more extensive introduction and an English translation of Schlegel's essay
