This essay asks what archival sound objects—in this case a vast stockpile of bootleg music recordings—can tell us about cultures of listening and the cultivation of intimacy through sound under state socialism. It combines ethnographic and historical methodologies to analyze a format for popular music that circulated through an alternative economy in the People's Republic of Poland from the 1950s through the 1980s: the “sound postcard” (pocztówka dźwiękowa). These flimsy, often colorful, plastic rectangles contained copies of mainstream western, Polish, and Soviet popular musics on seven-minute records, sold hand-to-hand at markets and kiosks. In the twenty-first century, these polyethylene flexidiscs circulate as socialist ephemera with a nostalgic thrill, cherished for their obsolescence and provocative visual design reconstruct, but dismissed as poor fidelity transfers. I treat this archive as material history that contains aural traces allowing us to access socialities, affective experiences, and labor relations.

We present a new method to measure the rotational height gradient in the solar photosphere. The method is inspired from differential interferometric techniques, we applied it to spectroscopic observations in the FeI 630.15 nm obtained at the solar telescope THEMIS which is equipped with an efficient adaptive optics system. The spectroscopic data was used to obtain images of the granulation at different line cords formed at different heights in the photosphere. Cross-correlation allows us to measure small systematic shifts between similar images. When observations are performed out of the center of the solar disk, the perspective effect gives rise to a radial shift between images formed at different heights. The measurement of this shift provides us with their formation-height difference. At the center of the disk the perspective effect vanishes but we measured a systematic retrograde shift along the east/west direction of the images formed at higher heights. The measured shifts are proportional to the formation height of the images. We interpret these findings as the evidence of a decrease of the rotational velocity with height in the low photosphere of the Sun and we give an estimate of this gradient.

This note on Propertius 4.7 argues that Cynthia, repeatedly cast in the role of the poet's Muse, rejects the burden of inspiration through a learned choice of words (non tamen insector, 4.7.49). The verb insector constitutes a clear reference to the invocation of the Camena in Livius Andronicus and of the Muse in Ennius. Cynthia recalibrates the parlance of poetic inspiration to end her relationship with Propertius, both as his puella and as his Muse.

Before colonialism, Gbe women enjoyed a social status on par with men. However, there has been a shift in the postcolonial social structure of Gbe societies. Modern capitalism, which accompanied colonial structures, privileged men, eroding many woman-empowering practices. This article examines Ogu women’s marginality through an ethnographic study of gangbe (a musical genre exclusive to married Ogu women). I argue that the sources of Ogu women’s marginality are interlocking, involving oppression stemming from colonial structures and the values of contiguous Yorùbá people. I propose a collaborative intervention that upends typical power structures that privilege Western and Yorùbá ideation over Indigenous Ogu knowledge, values, and practices.

Both observations and theoretical studies have convincingly shown that outflows (i.e., wind and jet) are common phenomena from black hole accretion systems with various accretion rates, although the physical driving mechanisms are not exactly same for different accretion modes. Outflows are not only important in the dynamics of black hole accretion, but also play an important role in AGN feedback; therefore it is crucial to investigate their main physical properties including mass flux and velocity. In this paper we summarize recent studies in investigating the properties and driving mechanisms from black hole accretion flows with various accretion rates.

This article proposes a new methodology for engaging with early modern legal metaphor. It argues that a full account of the trope must integrate its legal-historical, cultural, literary, and philosophical dimensions. After discussing what makes early modern legal metaphor unique (and thus uniquely challenging to decipher), I consider various philosophical, legal, cognitive, and literary approaches to the rhetorical figure and demonstrate how each perspective adds additional insight to its untangling in juridical contexts. The article culminates in a reading of a single metaphor taken from lawyer John Exton's treatise “The maritime dicæologie, or, the Sea-jurisdiction of England” (1664): “The ship dieth at sea.” Ultimately, I argue that this metaphor references admiralty actions in rem, which were integral to the functioning of the sixteenth- and seventeenth-century English High Court of Admiralty, an interpretation that emerges only when accounting for the trope in both its textual and intertextual frameworks.

Un texte récemment mis au jour dans les environs de Lepti Minus (Lamta, dans le Sahel tunisien), gravé sur sur la face principale d'une base de statue, apporte un éclairage substantiel concernant l’édification de l'amphithéâtre de la ville: le contexte d‘édification, la nature du financement et l'identité des évergètes qui l‘ont pris en charge. Il s'agit donc d'un hommage public que le populus Leptitanorum a rendu à L. Octauius Felix, un notable local, membre de l'ordre équestre, coopté en qualité de patron de la cité. Le texte présente ainsi des centres d'intérêt multiples: des considérations onomastiques et sociales, le cursus équestre du notable laptitain, L. Octauius Felix, du primipilat, à la préfecture du camp de la Legio VII Gemina, en Espagne, et a prise en charge de la construction de l'amphithéâtre.

The study’s focus on the modulation of geomagnetism by low latitude solar magnetically activity, including coronal mass ejections (CMEs), solar flares, and solar energetic particles (SEPs). It mentions the Babcock–Leighton (B-L) dynamo model used to predict sunspot numbers in Solar Cycle 25 (SC25) and highlights the challenges in understanding aspects such as the regeneration of the poloidal field and the occurrence of magnetic regions, active longitudes, and coronal holes. The abstract introduces the study’s concentration on the activity of polar regions using chromosphere jets activity proxies and other parameters like polar faculae density and cool ejection events. It also mentions the observation of chromospheric prolateness during the minimum solar activity periods.
