    Documenting Cordage Impressions on Archaeological Ceramics: A Methodological Comparison of Casting and Digital Representation

    The analysis of cordage and fabrics from the impressions and markings on pottery has traditionally been conducted by casting the pottery sherds with a plastic or liquid media to make a positive. This positive is then analyzed by measuring attributes under a low-power microscope with calipers. Original Sculpey® is one casting media that has been popular because of its price, accessibility, detail of cast, and permanency of the casts after curing. However, it has been found to impart an organic chemical signature on the sherds, which would bias residue analyses. Further, the plasticizer in Original Sculpey® can soften certain plastics, notably Paraloid B-72, which is often used on pottery as a consolidant. 3D scanning, then, theoretically can be used to create digital representations of the impressions and markings in pottery, while avoiding damage to the sherds and other conservation concerns. The NextEngine 3D laser scanner was tested in the analysis of seven sherds with varying qualities of impressions and markings. Results revealed that the method one uses depends not only on the quality desired and the conservation of the sherd, but also cost, time, and expertise available to the researcher. While the NextEngine itself may not be able to achieve the level of detail needed to match casting methods, the technology can be nonetheless useful for impressed sherd documentation in the near future

    The Human Phenotype Ontology in 2024: phenotypes around the world.

    The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English. Since our last report, a total of 2239 new HPO terms and 49235 new HPO annotations were developed, many in collaboration with external groups in the fields of psychiatry, arthrogryposis, immunology and cardiology. The Medical Action Ontology (MAxO) is a new effort to model treatments and other measures taken for clinical management. Finally, the HPO consortium is contributing to efforts to integrate the HPO and the GA4GH Phenopacket Schema into electronic health records (EHRs) with the goal of more standardized and computable integration of rare disease data in EHRs

    Paroles d’Évangiles

    « C’est du hault Alemant ! » grognaient les sujets du roi François Ier en parlant des textes barbares qui passaient le Rhin sans habit latin. Nous le disons encore aujourd’hui, mais « c’est du chinois »... Les traductions commentées de pamphlets ici présentées veulent initier les Français aux débats d’idées de la Réforme luthérienne, si méconnue hors des terres germaniques. Pour défendre leur cause, les contemporains de Luther ont su en effet inventer en quelques années toutes les techniques médiatiques de notre modernité. Ce choix de pamphlets traduits en témoigne. Les historiens ou les linguistes de notre temps, de plus en plus sensibles aux richesses de la « libellistique » ancienne, trouveront leur pâture dans ces textes savoureux, qui sont replacés dans leur contexte historique et littéraire. Tous ceux qui veulent comprendre l’explosion multiforme de la Réformation, sa puissance intellectuelle et reli­gieuse, sa virulence sociale, doivent aborder cette littérature difficile mais essentielle, mise enfin à la portée de ceux qui ne savent pas les langues
