We give a detailed account of Hugo Volger's early, but rarely mentioned, construction of free algebras for a Lawvere-Linton theory of 1967 and analyze how it differs from subsequent work of the 1970s.

For a morphism f in a category C with sufficiently many finite limits and colimits, we discuss an elementary construction of a decomposition of f through objects P and N which, if C happens to have a zero object, amounts to the standard decomposition

Context. Characterizing mission-accessible asteroids using telescopic observations is fundamental for target-selection and planning for spacecraft missions. Near-Earth asteroids on Earth-like orbits are of particular importance for applications such

We have conducted extremely ultra-deep pencil beam observations for new satellites around both Uranus and Neptune. Tens of images on several different nights in 2021, 2022 and 2023 were obtained and shifted and added together to reach as faint as 26.

Saturn has long been the only giant planet in our solar system without any known Trojan members. In this paper, with serendipitous archival observations and refined orbit determination, we report that 2019 UO$_{14}$ is a Trojan of the gas giant. Howe

In this article, the effect a moving target has on the signal-to-interference-plus-noise-ratio (SINR) for high time-bandwidth noise radars is investigated. To compensate for cell migration we apply a computationally efficient stretch processing algor

Building on the notion of normed category as suggested by Lawvere, we introduce notions of Cauchy convergence and cocompleteness which differ from proposals in previous works. Key to our approach is to treat them consequentially as categories enriche

Bedload transport occurs when a bed composed of sedimentary grains becomes mobile in response to the shearing by a flow of liquid. It shapes the landscapes of Earth and other planetary bodies by promoting the formation and growth of various multiscal

Following the Pluto fly-by of the New Horizons spacecraft, the mission provided a unique opportunity to explore the Kuiper Belt in-situ. The possibility existed to fly-by a Kuiper Belt object (KBO) as well as to observe additional objects at distance

Pursuing a new approach to the study of infinite games in combinatorics, we introduce the categories $\mathbf{Game}_{{A}}$ and $\mathbf{Game}_{{B}}$ and provide novel proofs of some classical results concerning topological games related to the dualit
