In the following work we delve into the scientific, technical and also political context of the last excavation directed by Alberto Rex González at the Pucará de Andalgalá, prior to the coup d’état of March 24, 1976. The trigger for this analysis results from the discovery of materials from that campaign stored in the Archaeolo-gy División of La Plata Museum. Through historical reconstruction based on the review of documents and bibliographic references, interviews and analysis of the material recovered from the archeology division this article aims to explain how Alberto Rex González designed the field work, the context in which the campaign took place, what previous ideas led him to undertake the project and what could have been the reasons for abandoning it

This paper presents a thoroughly automated method for identifying and interpreting cuneiform characters via advanced deep-learning algorithms. Five distinct deep-learning models were trained on a comprehensive dataset of cuneiform characters and evaluated according to critical performance metrics, including accuracy and precision. Two models demonstrated outstanding performance and were subsequently assessed using cuneiform symbols from the Hammurabi law acquisition, notably Hammurabi Law 1. Each model effectively recognized the relevant Akkadian meanings of the symbols and delivered precise English translations. Future work will investigate ensemble and stacking approaches to optimize performance, utilizing hybrid architectures to improve detection accuracy and reliability. This research explores the linguistic relationships between Akkadian, an ancient Mesopotamian language, and Arabic, emphasizing their historical and cultural linkages. This study demonstrates the capability of deep learning to decipher ancient scripts by merging computational linguistics with archaeology, therefore providing significant insights for the comprehension and conservation of human history.

Chemical clocks, based on age-sensitive stellar abundance ratios, offer a powerful and scalable approach to reconstruct the formation history of the Milky Way. This white paper outlines how wide-field, high-resolution spectroscopy can transform chemical clocks into precise and broadly applicable stellar age estimators when combined with astrometry and asteroseismology. We summarize the current limitations, including calibration across Galactic environments and the impact of internal stellar evolution, and define the observational requirements needed to overcome them. The Wide-field Spectroscopic Telescope (WST), with its large field of view, high multiplex, and broad wavelength coverage at high spectral resolution, is uniquely suited to deliver the homogeneous datasets required to map the age structure of the Galaxy at unprecedented scale. Such a capability will enable decisive progress in Galactic archaeology and stellar evolution studies.

Cosmic chronometers offer a model-independent way to trace the expansion history of the Universe via the dating of passively evolving objects. This enables testing the validity of cosmological models without concrete assumptions of their energy content. The main goal of this work is to derive model-independent constraints on the Hubble parameter up to $z \sim 0.4$ using stellar ages from the fitting of Lick index absorption lines in passively evolving galaxies. Contrary to recent related works that rely on finite differences to obtain a discrete measurement of the expansion of the Universe at an average redshift, our goal is to perform a cosmographic fit of $H(z)$ in terms of the Hubble constant ($H_0$) and the deceleration ($q_0$) and jerk ($j_0$) parameters. We carefully select spectra of massive and passively evolving galaxies from the SDSS Legacy Survey. After applying a stacking procedure to ensure a high signal-to-noise ratio, the strength of Lick indices is fit using two stellar population models (TMJ and Knowles) to derive stellar population parameters. A cosmographic fit to the stellar ages is performed, which in turn enables the sampling of the Hubble parameter within the considered redshift range. The baseline result comes from using the TMJ-modelled ages, and it yields a value of $H_0 = 70.0^{+4.1}_{-7.6} \text{ km s}^{-1} \text{ Mpc}^{-1}$ for the Hubble constant, where uncertainties refer only to the statistical treatment of the data. The sampling of the Hubble parameter at $0.05 < z < 0.35$ is competitive with discreet model-independent measurements from the literature. We finally draw attention to an unexpected oscillating pattern in a number of critical indices with respect to redshift, which translates into a similar behaviour in the $t-z$ relations. These features have never been discussed before, although they are present in previous measurements.

This essay explores a techno-artistic experiment that reanimates a 1980s East German typewriter using a contemporary AI language model. Situated at the intersection of media archaeology and speculative design, the project questions dominant narratives of progress by embedding generative AI in an obsolete, tactile interface. Through public exhibitions and aesthetic intervention, we demonstrate how slowness, friction, and material render artificial intelligence not only visible but open to critical inquiry. Drawing on concepts such as zombie media, technostalgia, and speculative design, we argue that reappropriating outdated technologies enables new forms of critical engagement. Erika - the AI-enabled typewriter - functions as both interface and interruption, making space for reflection, irony, and cultural memory. In a moment of accelerated digital abstraction, projects like this foreground the value of deliberate slowness, experiential materiality, and historical depth. We conclude by advocating for a historicist design sensibility that challenges presentism and reorients human-machine interaction toward alternative, perceived futures.

Los estudios sobre el Neolítico en el País Vasco se han desarrollado de manera importante en las últimas décadas. En el estado actual de conocimientos se puede describir una etapa cultural no retardataria y que presenta grandes similitudes con el desarrollo en zonas limítrofes. Sí es importante señalar que al sur del País se localiza uno de los pocos conjuntos que han sido definidos como «pioneros» en la Península Ibérica. La aplicación de novedosas técnicas analíticas hacen que el conocimiento del Neolítico esté ofreciendo aspectos desconocidos hasta ahora en esta etapa.

3D surface reconstruction from point clouds is a key step in areas such as content creation, archaeology, digital cultural heritage, and engineering. Current approaches either try to optimize a non-data-driven surface representation to fit the points, or learn a data-driven prior over the distribution of commonly occurring surfaces and how they correlate with potentially noisy point clouds. Data-driven methods enable robust handling of noise and typically either focus on a global or a local prior, which trade-off between robustness to noise on the global end and surface detail preservation on the local end. We propose PPSurf as a method that combines a global prior based on point convolutions and a local prior based on processing local point cloud patches. We show that this approach is robust to noise while recovering surface details more accurately than the current state-of-the-art.

Galactic archaeology largely relies on precise ages of distant evolved stars in the Milky Way. Nowadays, asteroseismology can deliver ages for many red giants observed with high-cadence, high-precision photometric space missions. Our aim is to quantify age uncertainties of slowly-rotating red giants due to the cumulative effect of their fast rotation during core-hydrogen burning. Their rotation in earlier evolutionary phases caused mixing resulting in heavier helium cores and the prolongation of their main sequence. These rotational effects are usually ignored when age-dating red giants, despite our knowledge of fast rotation for stars with $M\ge1.3\,$M$_\odot$. We use a sample of 490 $γ$ Doradus pulsators with precise asteroseismic estimates of their internal rotation rate and with luminosity estimates from Gaia. For this sample, which includes stars rotating from nearly 0 to about 60% of the critical rate, we compute the cumulative effect on the age in their post-main sequence evolution caused by rotational mixing on the main sequence. We use stellar model grids with different physical prescriptions mimicking rotational mixing to assess systematic uncertainties on the age. With respect to non-rotating models, the sample of 490 stars, as red giant progenitors, reveals age differences up to 5% by the time they start hydrogen-shell burning when relying on the theory of rotationally induced diffusive mixing as included in the MIST isochrones. Using rotational mixing based on an advective-diffusive approach including meridional circulation leads to an age shift of 20% by the time of the TRGB. Age-dating of red giants is affected by the cumulative effect of rotational mixing during the main sequence. Such rotationally-induced age shifts should be taken into account in addition to other effects if the aim is to perform Galactic archaeological studies at the highest precision. (abridged)

The archaeozoological study of the Indus Valley Civilisation, particularly in the last few decades, has resulted in a better understanding of human-animal interactions, providing information about species that have been commonly found at Indus Valley sites, both wild and domestic. This is also indicative of the nature of animal-based subsistence at these settlements and the interplay between humans, animals, and the environment. However, these studies have largely been conducted at the level of individual sites, and despite extensive analysis of excavated faunal materials, synthesis of faunal data across different developmental phases of this civilisation and its regions, has rarely taken place. As a result, there exists little understanding of broader animal utilisation patterns within the Indus Valley Civilisation and their relation to climate and landscape. This article produces a comparative analysis of domestic animal utilisation by combining and reanalysing faunal data from different regions of the Indus Valley Civilisation. Our analysis reveals extreme disparity in the spatial and temporal distribution of domesticated animals within this Civilisation. Of the different regions, the amount of data required for interpretation is only available from Haryana and Gujarat, and this largely pertains to the Mature Harappan period, with the Early and Late Harappan phases being grossly underrepresented. Although cattle, buffalo, goats, sheep, and pigs were the primary domesticates across regions, their distribution and economic importance varied and changed over time. This variation may indicate differentiated regional and temporal cultures and adaptations to climatic change.

The original promise of the internet was that it could have served as a tool whereby the general public could access, a single mouse-click away, unlimited amounts of reliable open access archaeological information supplied by academia or the museum world. This vision is in practice frustrated by the current form of that resource. Since changes that started taking place from 2015, the internet has increasingly been developing primarily as a commercial tool of modern capitalist trade. The casual searcher for information on a large range of archaeological phenomena will therefore primarily be faced with page after page of adverts offering examples of archaeological artefacts for sale and texts about their private collection.

Historical emphasis on writing mastery has shifted with advances in generative AI, especially in scientific writing. This study analysed six AI chatbots for scholarly writing in humanities and archaeology. Using methods that assessed factual correctness and scientific contribution, ChatGPT-4 showed the highest quantitative accuracy, closely followed by ChatGPT-3.5, Bing, and Bard. However, Claude 2 and Aria scored considerably lower. Qualitatively, all AIs exhibited proficiency in merging existing knowledge, but none produced original scientific content. Inter-estingly, our findings suggest ChatGPT-4 might represent a plateau in large language model size. This research emphasizes the unique, intricate nature of human research, suggesting that AI's emulation of human originality in scientific writing is challenging. As of 2023, while AI has transformed content generation, it struggles with original contributions in humanities. This may change as AI chatbots continue to evolve into LLM-powered software.

We demonstrate the utility and reproducibility of the saltmarsh foraminifera-based ‘geological tide gauge’ (GTG) approach by developing two independent records of relative sea-level (RSL) change for Dublin, Ireland. Our records, recovered from two different saltmarshes, indicate that RSL rose at a century-scale rate of 1.5 ± 0.9 mm yr–1 over the last 200 years. This compares favourably with the shorter, but more precise, mean sea level (MSL) record from the Dublin Port tide gauge, which indicates long-term (1953–2016 CE) rise at a rate of 1.1 ± 0.5 mm yr–1. When corrected for the influence of glacio-isostatic adjustment our saltmarsh-based reconstruction suggests sea levels in Dublin rose at a rate of 1.6 ± 0.9 mm yr–1 since the start of the 19th century, which is in excellent agreement with the regional value of MSL rise over the same period (1.5 ± 0.2 mm yr–1) calculated from a compilation of tide gauge records around Britain. Whilst our record has decadal-scale temporal resolution (1 sample every 8 years), we are currently unable to resolve multidecadal-scale variations in the rate of sea-level rise which are masked by the size of the vertical uncertainties (± 20 cm) associated with our reconstruction of palaeomarsh-surface elevation. We discuss the challenges of applying the GTG approach in the typically minerogenic saltmarshes of the NE Atlantic margin and outline potential solutions that would facilitate the production of Common Era RSL reconstructions in the region.

This article discusses the chaîne opératoire concept in prehistoric archaeology, traditionally employed for the study of lithic industries and ceramic production, and focuses on personal ornament manufacture. This category of non-functional objects has been analysed with the operational sequence approach in the framework of a research project aimed at the techno-functional study of prehistoric marble artefacts. Throughout an experimental approach, the study presents the actions and choices made by the artisans to produce marble beads and tries to understand the role and social-cultural meaning that these items had for the Copper Age communities in Tuscany. Finally, our study proved that the beginning of the use of the Apuan marble can be traced back to the sixth millennium BC, and it was connected with the production of personal ornaments, reaching its peak during the Copper Age.

Recovering the birth radii of observed stars in the Milky Way is one of the ultimate goals of Galactic Archaeology. One method to infer the birth radius and the evolution of the ISM metallicity assumes a linear relation between the ISM metallicity with radius at any given look-back time. Here we test the reliability of this assumption by using 4 zoom-in cosmological hydrodynamic simulations from the NIHAO-UHD project. We find that one can infer precise birth radii only when the stellar disk starts to form, which for our modeled galaxies happens ~ 10 Gyr ago, in agreement with recent estimates for the Milky Way. At later times the linear correlation between the ISM metallicity and radius increases, as stellar motions become more ordered and the azimuthal variations of the ISM metallicity start to drop. The formation of a central bar and perturbations from mergers can increase this uncertainty in the inner and outer disk, respectively.

Este artículo, de marcado carácter metodológico, ofrece una aproximación detallada al sistema de información histórico- arqueológico diseñado desde el proyecto de investigación Muntanya Viva para el estudio del poblamiento medieval en la zona del Pallars Jussà entre los siglos IV y XII. Se trata de un modelo de datos relacional que permite la integración de toda la información disponible, ya provenga de fuentes escritas o arqueológicas, y su posterior representación en una cartografía digital a través de un Sistema de Información Geográ_ca (SIG). Todo esto con el objetivo de poder analizar sincrónicamente la relación entre los distintos elementos que configuraban el paisaje en un momento concreto, así como diacrónicamente su evolución a lo largo del tiempo.

In the last decades the rapid development of technologies and methodologies in the field of digitization and 3D modelling has led to an increasing proliferation of 3D technologies in the Cultural Heritage domain. Despite the great potential of 3D digital heritage, the "special effects" of 3D may often overwhelm its importance in research. Projects and consortia of scholars have tried to put order in the different fields of application of these technologies, providing guidelines and proposing workflows. The use of computer graphics as an effective methodology for CH research and communication highlighted the need of transparent provenance data to properly document digital assets and understand the degree of scientific quality and reliability of their outcomes. The building and release of provenance knowledge, consisting in the complete formal documentation of each phase of the process, is therefore of fundamental importance to ensure its repeatability and to guarantee the integration and interoperability of the generated metadata on the Semantic Web. This paper proposes a methodology for documenting the planning and creation of 3D models used in archaeology and Cultural Heritage, by means of an application profile based on the CIDOC CRM ecosystem and other international standards.

Non-invasive volumetric imaging can now capture the internal structure and detailed evidence of ink-based writing from within the confines of damaged and deteriorated manuscripts that cannot be physically opened. As demonstrated recently on the En-Gedi scroll, our "virtual unwrapping" software pipeline enables the recovery of substantial ink-based text from damaged artifacts at a quality high enough for serious critical textual analysis. However, the quality of the resulting images is defined by the subjective evaluation of scholars, and a choice of specific algorithms and parameters must be available at each stage in the pipeline in order to maximize the output quality.

ABSTRACT People have harnessed beneficial microbes to preserve, protect, and improve food for thousands of years. However, the significance and techniques of food fermentation are poorly understood in prehistoric archaeology. This paper explains what food fermentation is and discusses its relevance in an early farming context. It sets out the beginnings of a theoretical and material framework that can be drawn upon for further study of this crucial but overlooked aspect of prehistoric food cultures. Focus is on the British Neolithic, but the central concepts are applicable in other periods and places.
