Uncertainty has attached to a medieval library catalogue entry mentioning Papias cum sermonibus diversis at Stams Abbey. Most recent editors of Papias have suspected that it refers to the medieval lexicographer rather than the second-century Christian author of the same name. This note calls attention to a marginal citation in a Stams manuscript from the lexicographer that helps put to rest the hypothesis of a full Latin manuscript of Papias of Hierapolis.

Beginning with Soliloquy I for solo violin in 1998, the author has been engaged in creating a series of highly virtuosic solo pieces for various instruments. Each piece presents a different character, yet all are framed by a single protagonist who narrates in different languages.

This article focuses particularly on analyses of Soliloquies II, VI, VII, VIII and IX, but also offers a discussion of the genesis of and processes involved in the whole cycle, which now embraces instruments from every section of the orchestra; the most recent, Soliloquy IX, for solo trumpet, was written in 2022. The suitability of the title Soliloquy is also considered; this article in turn could itself be considered a soliloquy.

Archaeologists in North America and elsewhere are increasingly examining long-term Indigenous presence across multiple colonial systems, despite lingering conceptual and methodological challenges. We examine this issue in California, where archaeologists and others have traditionally overlooked Native persistence in the years between the official closing of the region's Franciscan missions in the 1830s and the onset of US settler colonialism in the late 1840s. In particular, we advocate for the judicious use of the documentary record to ask new questions of Indigenous life during this short but critical period, when many Native Californians were freed from the missions and sought new lives in their homelands or in emerging urban areas. We offer examples from our individual and collective research—undertaken in collaboration with the Muwekma Ohlone Tribe—regarding long-term Native persistence in the San Francisco Bay Area to demonstrate how archival evidence can illuminate four interrelated areas of daily life that could be investigated archaeologically, including resistance, freedom, servitude, and personal adornment. By using the written record to regain a sense of subjective time, these topics and others could stimulate new, interdisciplinary, and collaborative research that more firmly accounts for Indigenous people's enduring presence across successive waves of Euro-American colonialism.

In this paper we discuss sudoku-solving strategies and how graph theory can be used to explain some of the advanced techniques. There are many websites that provide tutorials on solving sudoku puzzles. The sites [1] and [2] discuss the xy-chain technique, and the two explanations are quite different. We will define xy-chains as paths in a graph, and properties of the paths show why the technique works.

This article was based on a presentation that was given at the IFLA-Art Libraries Section Satellite Conference. In an effort to push toward a more multidisciplinary and holistic approach to the data generated throughout the National Gallery of Art in Washington, DC, staff have been investigating new ways in which to amass, organize, and use that data. Segueing from a GIS mapping initiative, one such project sought to amalgamate disparate kinds of data centering around pigment analysis. This led to a multidepartment team trialing software solutions, raising questions and identifying challenges about how the institution creates and standardizes its data, and what changes are needed as we look to the future.

This paper is the first part in a series of three papers devoted to the study of enumerative invariants of abelian surfaces through the tropical approach. In this paper, we consider the enumeration of genus g curves of fixed degree passing through g points. We compute the tropical multiplicity provided by a correspondence theorem due to T. Nishinou and show that it is possible to refine this multiplicity in the style of the Block–Göttsche refined multiplicity to get tropical refined invariants.

The United States and United Kingdom have carried out a series of strikes upon Yemeni territory since January 2024. The acting States have justified these on the basis of the right of self-defence in response to the series of attacks that have been perpetrated by the Houthi group in Yemen against various commercial and military vessels in the Red Sea. On the face of it this was a relatively straightforward justification. Yet, when subjected to analysis it becomes evident that not only is the justification itself not clear, but that the law governing the actions—the jus ad bellum—is not sufficiently settled to provide clear parameters by which to assess the legality of the strikes. Furthermore, the strikes themselves, and the purposes for which they were undertaken, may have set a precedent with unforeseeable consequences.

Aiming at the error estimation problem of a radar detection system when the variation law of system error is unknown, an improved Gaussian mean-shift radar dynamic error registration algorithm (IGMSR) is proposed. The algorithm can effectively adapt to the variation of system error when the variation law of system error is unknown. The IGMSR algorithm uses the mean-shift method to contribute different characteristics to the estimation results of different sample points, and constructs weight coefficients according to the deviation of sample points from the mean and sampling time. The simulation results show that more than 90% of the constant system errors can be eliminated; for the systematic error with slow change, more than 80% of the bias can be eliminated in real time, while a previous method of Zhu and Wang (2018) can only eliminate 60% of the systematic error and require the change law to be known. This method overcomes the influence of random error and abnormal point, and the estimation results are more robust.

The International Regulations for the Prevention of Collisions at Sea (IRPCS) provide a comprehensive set of instructions for watchkeeping officers to follow and prevent collisions at sea. This study compares how six newly qualified deck officers and six Master Mariners, who were all trained at the same college, applied the IRPCS. Individual, semi-structured interviews were used to uncover how the 12 participants applied and interpreted the rules for three authentic scenarios. Phenomenography was used to capture the qualitatively different means by which participants interpreted the IRPCS. For basic collision avoidance situations, the results indicated little difference between the cohorts' ability to interpret and apply the IRPCS. However, when the scenarios became more complicated, Master Mariners outperformed newly qualified deck officers. In these cases, Master Mariners displayed a greater capacity to assess the overall situation, whereas newly qualified deck officers tended to simplify by focusing on a single rule. These findings indicate that training needs to focus on developing situational awareness; and training scenarios need to incorporate multiple vessels in authentic scenarios to enhance newly qualified deck officers' capacities to interpret the IRPCS.
