The object of the present article is to collect and analyse passages from narrative sources concerning monasticism in the Byzantine prefecture of Africa in the sixth to seventh centuries, in an attempt to determine the nature and extent of the monastic movement in the area. Due to the fragmentary nature of the surviving source base and its concentration around events of a political nature and relating to Christological controversies, the narrative texts (including the works of Procopius of Caesarea, the chronicle of Victor of Tonnona, and hagiographic literature) were also confronted with epistolographic and normative material, allowing for a more complete picture of the subject under study. The analysis has shown that there is no apparent continuity in the existence of monastic foundations between the Late Roman period, Vandal rule and Byzantine times; moreover, the information appearing in the sixth and seventh centuries basically concerns only monasteries and monks active in the area of Africa Proconsularis. The largest amount of data is provided by the Greek sources, which refer mainly to the situation in the first half of the seventh century and the Monothelite controversy, showing Africa as a place of settlement for numerous Eastern monks, but without mentioning the Latin-speaking monastic structures that had existed there before. The picture obtainable from the narrative of Byzantine monasticism in the area is therefore fragmentary and in many places hypothetical.

The fame of St Menas, the Egyptian martyr, spread far beyond Egypt, extending into historical Ethiopia. This widespread reverence stems from the longstanding unity between the Churches of Alexandria and Ethiopia, alongside the significant translation of Copto-Arabic texts into the classical Ethiopic language. By the fourteenth century, The Life and Martyrdom of St Menas was translated into Ge‘ez and became part of the Gadla Samāʽetāt collection of accounts on other prominent saints and martyrs. A concise version of St Menas’s acts appears in the hagiographical compilation for liturgical use, the Synaxarium. Ethiopia commemorates St Menas on Ḫedār 15 and the construction of his shrine at Maryut on Sanē 15. The latter occasion entails reading aloud a comprehensive collection of nineteen miracles, also translated from Arabic. The image of a saint who defends devout pilgrims like a knight, protects his sanctuary, heals the sick, liberates the possessed, punishes sins, repairs damage, and bestows blessings upon worshippers, evoked awe, reverence, and piety, especially in the Horn of Africa. Additional texts, including hymns and antiphons, further underscore the cult’s vitality. St Menas’s canonical depiction on horseback aligns with the broader tradition of equestrian saints, a frequent motif in Ethiopian iconography.

Most conference papers present new results, but this paper will focus more on opportunities for the audience to make their own contributions. This paper is intended to challenge the community to think more broadly about what we can do with comparable corpora. We will start with a review of the history, and then suggest new directions for future research. This was a keynote at BUCC-2025, a workshop associated with Coling-2025.

We review the conservation laws of magnetohydrodynamics (MHD) in an expanding homogeneous and isotropic Universe that can be applied to the study of early Universe physics during the epoch of radiation domination. The conservation laws for a conducting perfect fluid with relativistic bulk velocities in an expanding background are presented (for the first time in their non-conservation form, i.e., as dynamical equations for the velocity and energy density fluid variables), and extending previous results that apply in the limit of subrelativistic bulk motion. Furthermore, it is shown that the subrelativistic limit presents new corrections that have not been considered in previous work. We discuss the conformal invariance of the MHD equations for a radiation-dominated fluid and different types of scaling of the fluid variables that are relevant for other equations of state when the bulk velocity is subrelativistic. In particular, we review the super-comoving coordinates that have been proposed for matter-dominated fluids and present this choice of coordinates for any equation of state. First-order fluid dynamics to include imperfect relativistic fluids and the scaling of the transport coefficients with temperature in the early Universe are presented. We review the propagation of sound waves, Alfvén waves, and magnetosonic waves in the early Universe plasma. The Boris correction for relativistic Alfvén speeds is presented and adapted for early Universe applications. This review is an extension, including new results, of part of the lectures presented at the minicourse "Simulations of Early Universe Magnetohydrodynamics" lectured by A. Roper Pol and J. Schober at EPFL, as part of the six-week program "Generation, evolution, and observations of cosmological magnetic fields" at the Bernoulli Center in May 2024.

Literature reviews play a crucial role in scientific research for understanding the current state of research, identifying gaps, and guiding future studies on specific topics. However, the process of conducting a comprehensive literature review is yet time-consuming. This paper proposes a novel framework, collaborative knowledge minigraph agents (CKMAs), to automate scholarly literature reviews. A novel prompt-based algorithm, the knowledge minigraph construction agent (KMCA), is designed to identify relations between concepts from academic literature and automatically constructs knowledge minigraphs. By leveraging the capabilities of large language models on constructed knowledge minigraphs, the multiple path summarization agent (MPSA) efficiently organizes concepts and relations from different viewpoints to generate literature review paragraphs. We evaluate CKMAs on three benchmark datasets. Experimental results show the effectiveness of the proposed method, further revealing promising applications of LLMs in scientific research.

Excitons in quantum dots are excellent sources of polarization-entangled photon pairs, but a quantitative understanding of their interaction with the nuclear spin bath is still missing. Here we investigate the role of hyperfine energy shifts using experimentally accessible parameters and derive an upper limit to the achievable entanglement fidelity. Our results are consistent with all available literature, indicate that spin-noise is often the dominant process limiting the entanglement in InGaAs quantum dots, and suggest routes to alleviate its effect.

Complying with the EU AI Act (AIA) guidelines while developing and implementing AI systems will soon be mandatory within the EU. However, practitioners lack actionable instructions to operationalise ethics during AI systems development. A literature review of different ethical guidelines revealed inconsistencies in the principles addressed and the terminology used to describe them. Furthermore, requirements engineering (RE), which is identified to foster trustworthiness in the AI development process from the early stages was observed to be absent in a lot of frameworks that support the development of ethical and trustworthy AI. This incongruous phrasing combined with a lack of concrete development practices makes trustworthy AI development harder. To address this concern, we formulated a comparison table for the terminology used and the coverage of the ethical AI principles in major ethical AI guidelines. We then examined the applicability of ethical AI development frameworks for performing effective RE during the development of trustworthy AI systems. A tertiary review and meta-analysis of literature discussing ethical AI frameworks revealed their limitations when developing trustworthy AI. Based on our findings, we propose recommendations to address such limitations during the development of trustworthy AI.

In the iron--chromium system, Fe$_{x}$Cr$_{1-x}$, a wide dome of spin-glass behavior emerges when the ferromagnetism of iron is suppressed and the antiferromagnetism of chromium emerges as a function of increasing iron content $x$. As both, the high-temperature state and the characteristic cluster size vary as a function of $x$, different regimes of spin-glass behavior may be compared in a single, isostructural material system. Here, we report a study of the spin dynamics across the freezing process into the spin-glass state for different iron concentrations ($x = 0.145$, $0.175$, $0.21$) using Modulation of IntEnsity with Zero Effort (MIEZE) spectroscopy. In the parameter range studied, the relaxation process observed experimentally may be described well in terms of a stretched exponential. In the reentrant cluster-glass regime, $x = 0.145$, this behavior persists up to high temperatures. In comparison, in the superparamagnetic regime, $x = 0.175$ and $x = 0.21$, a single relaxation time at elevated temperatures is observed. For all samples studied, the spin relaxation exhibits a momentum dependence consistent with a power law, providing evidence of a dispersive character of the spin relaxation.

Deep learning models that perform well often have high computational costs. In this paper, we combine two approaches that try to reduce the computational cost while keeping the model performance high: pruning and early exit networks. We evaluate two approaches of pruning early exit networks: (1) pruning the entire network at once, (2) pruning the base network and additional linear classifiers in an ordered fashion. Experimental results show that pruning the entire network at once is a better strategy in general. However, at high accuracy rates, the two approaches have a similar performance, which implies that the processes of pruning and early exit can be separated without loss of optimality.

We present the spectroscopic confirmation of a protocluster at $z=7.88$ behind the galaxy cluster Abell2744 (hereafter A2744-z7p9OD). Using JWST NIRSpec, we find seven galaxies within a projected radius of 60kpc. Although the galaxies reside in an overdensity around $>20\times$ greater than a random volume, they do not show strong Lyman-alpha emission. We place 2-$σ$ upper limits on the rest-frame equivalent width $<16$-$28$AA. Based on the tight upper limits to the Lyman-alpha emission, we constrain the volume-averaged neutral fraction of hydrogen in the intergalactic medium to be $x_{\rm HI} > 0.45$ (68% CI). Using an empirical $M_{\rm UV}$-$M_{\rm halo}$ relation for individual galaxies, we estimate that the total halo mass of the system is $\gtrsim 4\times10^{11}\,M_\odot$. Likewise, the line of sight velocity dispersion is estimated to be $1100 \pm 200$km/s. Using an empirical relation, we estimate the present-day halo mass of A2744-z7p9OD to be $\sim2\times10^{15}\,M_\odot$, comparable to the Coma cluster. A2744-z7p9OD is the highest redshift spectroscopically confirmed protocluster to date, demonstrating the power of JWST to investigate the connection between dark-matter halo assembly and galaxy formation at very early times with medium-deep observations at $<20$hrs total exposure time. Follow-up spectroscopy of the remaining photometric candidates of the overdensity will further refine the features of this system and help characterize the role of such overdensities in cosmic reionization.

We use standard tools of Archaeoastronomy to approach the study of orientations, possibly astronomical, of a group of colonial Christian churches. We present preliminary results of the analysis of the precise spatial orientation of nearly fifty chapels and churches of the Canary Island of Fuerteventura (Spain), most of them built from the period of the Norman conquest in the fifteenth century to the nineteenth century. Although some small chapels belonging to the manorial power of the island and other modern churches do not have a well-defined pattern of orientations, the vast majority of the religious constructions of the island (about 35 of the 48 analyzed) have their axis oriented within the solar range, between the extreme azimuths of the annual movement of the Sun when crossing the local horizon. Unlike what was found in other islands of the archipelago, these results suggest that the religious architecture of Fuerteventura faithfully follows the prescriptions contained in the texts of early Christian writers.

The study shows that there is a full parallel between Mary in the Annunciation and the baptism of believers. In the Oriental interpretation, the two-stage approach observed in the Annunciation scene: the Holy Spirit who cleanses and the Son who incarnates have their counterpart in the birth of a new man – a Christian who receives the Holy Spirit through the anointing with oil, and becomes a member of Christ in the waters of baptism. So we have a Mariology which is soteriologically oriented and inseparably connected with the person of Christ. This approach, biblical and in line with tradition, seems to be particularly interesting because it allows us to see the not always empha sized dimension of our Marian devotion.

Mowa Przeciwko Żydom, którzy mówią, że na nowo zostaną zgromadzeni jest dziewiętnastym wykładem w całej kolekcji Afrahata. Mędrzec perski kontynuuje i rozwija polemikę z nauczaniem judaizmu i rabinów babilońskiej diaspory. Pers podważa przekonanie Żydów oparte na prorockich obietnicach o ponownym zgromadzeniu Izraela i dowodzi fałszu ich interpretacji. Bóg odrzucił swój Naród Wybrany. Prorockie zapowiedzi odbudowy Izraela wypełnione zostały ostatecznie w powrocie z niewoli babilońskiej. Uprzywilejowaną postacią w antyżydowskiej argumentacji Persa jest prorok Daniel. Jego wizje wypełniły się w Jezusie Chrystusie i w zniszczeniu Jeruzalem, które nigdy już nie zostanie odbudowane.

Literature analysis facilitates researchers to acquire a good understanding of the development of science and technology. The traditional literature analysis focuses largely on the literature metadata such as topics, authors, abstracts, keywords, references, etc., and little attention was paid to the main content of papers. In many scientific domains such as science, computing, engineering, etc., the methods and datasets involved in the scientific papers published in those domains carry important information and are quite useful for domain analysis as well as algorithm and dataset recommendation. In this paper, we propose a novel entity recognition model, called MDER, which is able to effectively extract the method and dataset entities from the main textual content of scientific papers. The model utilizes rule embedding and adopts a parallel structure of CNN and Bi-LSTM with the self-attention mechanism. We evaluate the proposed model on datasets which are constructed from the published papers of four research areas in computer science, i.e., NLP, CV, Data Mining and AI. The experimental results demonstrate that our model performs well in all the four areas and it features a good learning capacity for cross-area learning and recognition. We also conduct experiments to evaluate the effectiveness of different building modules within our model which indicate that the importance of different building modules in collectively contributing to the good entity recognition performance as a whole. The data augmentation experiments on our model demonstrated that data augmentation positively contributes to model training, making our model much more robust in dealing with the scenarios where only small number of training samples are available. We finally apply our model on PAKDD papers published from 2009-2019 to mine insightful results from scientific papers published in a longer time span.

Efficient automated scheduling of trains remains a major challenge for modern railway systems. The underlying vehicle rescheduling problem (VRSP) has been a major focus of Operations Research (OR) since decades. Traditional approaches use complex simulators to study VRSP, where experimenting with a broad range of novel ideas is time consuming and has a huge computational overhead. In this paper, we introduce a two-dimensional simplified grid environment called "Flatland" that allows for faster experimentation. Flatland does not only reduce the complexity of the full physical simulation, but also provides an easy-to-use interface to test novel approaches for the VRSP, such as Reinforcement Learning (RL) and Imitation Learning (IL). In order to probe the potential of Machine Learning (ML) research on Flatland, we (1) ran a first series of RL and IL experiments and (2) design and executed a public Benchmark at NeurIPS 2020 to engage a large community of researchers to work on this problem. Our own experimental results, on the one hand, demonstrate that ML has potential in solving the VRSP on Flatland. On the other hand, we identify key topics that need further research. Overall, the Flatland environment has proven to be a robust and valuable framework to investigate the VRSP for railway networks. Our experiments provide a good starting point for further research and for the participants of the NeurIPS 2020 Flatland Benchmark. All of these efforts together have the potential to have a substantial impact on shaping the mobility of the future.

Blockchain technology has gained tremendous popularity both in practice and academia. The goal of this article is to develop a coherent overview of the state of the art in blockchain technology, using a systematic(i.e.,protocol-based, replicable), multivocal (i.e., featuring both white and grey literature alike) literature review, to (1) define blockchain technology (2) elaborate on its architecture options and (3) trade-offs, as well as understanding (4) the current applications and challenges, as evident from the state of the art. We derive a systematic definition of blockchain technology, based on a formal concept analysis. Further on, we flesh out an overview of blockchain technology elaborated by means of Grounded-Theory.
