This paper analyses the metaliterary statements that pervade the oeuvre of Ennodius of Pavia (a.d. 474–521) in order to reconstruct his underlying conception of language: its nature, power, function, limitations, and dangers. This new perspective provides a more nuanced insight into the paradoxical poetics of the author as well as his final renunciation to literature after his appointment as bishop of Pavia.

The Sun’s meridional circulation is a crucial component for understanding the Sun’s dynamo and its interior dynamics. However, the determination of meridional circulation is affected by a systematic center-to-limb (CtoL) effect, which introduces systematic errors 5–10 times stronger than the meridional-flow-induced travel-time shifts in deep-flow measurements. Recently, it was found that the CtoL effect has a significant acoustic-frequency dependence, while flow-induced travel-time shifts show little frequency dependence (Chen & Zhao 2018). This discovery forms the basis for designing a new method to remove the CtoL effect. We therefore propose a frequency-dependent approach to measure the CtoL effect and the flow-induced signals in the Fourier domain. In this work, we present this new method and compare time–distance measurements in different frequency bands with those obtained by previous time-domain methods. The results demonstrate consistency with conventional time-domain fitting methods in the dominant frequency range, promising the potential for conducting meridional flow inversion across a broader frequency spectrum.

Vitruvius’ book is chock full of bodies. It is by means of his oiled body that Dinocrates gains an audience with Alexander (2.praef.1), and by means of his naked one, and the equivalent body of water that it displaces, that Archimedes solves his well-known quandary (9.praef.9f.). The body is a living, vital thing (7.praef.2f.), even as it is a book, a body of work (7.praef.10), arising from a body of education (1.1.12). Most important of all, Vitruvius outlines a ‘body of architecture’ (corpus architecturae, 6.praef.7) to propagate and extend the reach of the deified Augustus, commander-in-chief (1.praef.1), and this idea arguably gives rise to that of the ‘body politic’ (corpus imperii). Vitruvius’ text has been interpreted in terms of these bodies in important studies by Indra Kagis McEwen and John Oksanish; both authors treat the body as replete with meaning, the site of contact between architecture and the political, between text and author. This chapter adds to our understanding of the repertoire of bodies in Vitruvius by looking at those earlier incarnations of circular and square bodies which Vitruvius inherits, and in terms of which he construes the human body as a site of ideal proportions.

Coronal rain is formed in the post-impulsive phase of solar flares due to the thermal instability of coronal plasma in EUV loops. As a result, the sub-terahertz (sub-THz) emission flux in the post-impulsive phase of solar flares can be increased due to the increasing of the optical thickness of the thermal source. This suggests that sub-THz observations can be used as a diagnostic tool for coronal rain.

This work is aimed to analyse the relationship between the sub-THz radiation and variations of the temperature and the emission measure of the EUV coronal plasma during the post-impulsive phase of the SOL2022-05-04T08:45 solar flare.

Based on the two-dimensional temperature and emission measure distributions obtained from the AIA/SDO EUV intensity data, it was found that the temperature decreases whereas the emission measure reaches the maximum near the sub-THz flare peak. This circumstance and peculiarities of the radiation time profiles in different wave ranges show evidence in favor of the significant contribution of the thermal coronal loop plasma to the flare sub-THz radiation at least for some flare events. The sub-THz emission may be associated with a coronal condensation, accompanied by the formation of coronal rain.

This article aims to analyse the finances of the Coimbra city council from 1557 to 1836. Our objective is to examine the causes of long-term changes in municipal revenue and expenditure, particularly during the extended period of decline that occurred between the mid-17th century and the late 18th century. This study will focus on the composition of revenue and expenditure, as well as on revenue collection mechanisms. We aim to present the empirical data on the revenue and expenditure components that allow us to understand the changes that took place. Finally, we hope to be able to explain the causes that led to significant variations in revenue and expenditure in a dialogue with existing literature. The primary sources used correspond to municipal revenue and expenditure books, supplemented by other sources such as legislation, correspondence and auction books.
