Digital technology has become crucial for the protection of cultural relics, enabling their acquisition, preservation, exhibition, and dissemination in a non-contact manner.At present, the three-dimensional(3D) visualization technology of cultural relics focuses on the research of non-true 3D visualization, which cannot provide continuous viewing angle and takes a long time to render. This paper focuses on the acquisition and reproduction of digital information related to cultural relics, and proposes to achieve the true 3D display of cultural relics from a continuous perspective based on integrated imaging(InIm). Building up on traditional InIm, an Element image array (EIA) generation algorithm based on local depth template matching is designed by using spatial geometry relation. Experimental results show that the algorithm not only enables naked-eye 3D visualization of cultural relics, but also the generation speed is more than twice that of the compared 3D display data source generation algorithm.

Paper-based cultural relics inevitably face a variety of diseases such as acidification, yellowing, and strength loss during long-term preservation, where weakly alkaline inorganic materials play an important role in their deacidification treatments. In this work, by simply adjusting the supersaturation of crystal growing solution without the use of any organic additives, one-dimensional (1D) and two-dimensional (2D) weakly alkaline materials—magnesium carbonate hydrates (MCHs)—were controllably synthesized. It is worth noting that the coatings of 1D/2D MCHs not only cause little change in chromatic aberration and water wettability, but also ensure their safety for alkali-sensitive pigments. Meanwhile, the deacidification, anti-aging, strength-enhancing, and flame-retardant effects of these materials have been tested on ancient book papers, all of which achieved good protective effects. In contrast, 1D MCH materials brought about significant enhancement in both mechanical strengths and flame-retardant effects, and the related effects were investigated. Based on this facile micromorphology control strategy, more low-dimensional nanomaterials are expected to be synthesized by design for the protection of paper-based relics, which will expand our knowledge on functional deacidification and protection mechanisms.

Three-dimensional digital modeling at actual scales is essential for digitally preserving cultural relics. While 3D reconstruction using a monocular camera offers a cost-effective solution, the lack of scale information in the resulting models limits their suitability for geometric measurements. Objects with monotonous textures, such as batteries, pose additional challenges due to insufficient feature points, increasing positional uncertainty. This article proposes a method incorporating point and line features to address the scale ambiguity in multi-view 3D reconstruction using monocular cameras. By pre-measuring the lengths of multiple sets of real line segments, building a lookup table, and associating the line features in different images, the table was input into the improved reconstruction algorithm to further optimize the scale information. Experimental results on real datasets showed that the proposed method outperformed the COLMAP method by 70.82% in reconstruction accuracy, with a scale recovery reaching millimeter-level accuracy. This method is highly generalizable, cost-effective, and supports lightweight computation, making it suitable for real-time operation on a CPU. [ABSTRACT FROM AUTHOR]

Transition economies, on the one hand, grapple with a communist legacy; on the other hand, they seek the optimal institutionalization for knowledge generation, dissemination, and commercialization to compete globally. However, the incumbent knowledge of certain aspects of their innovation systems remains very limited. In particular, intra-organizational cultural relics of the past and their inter-organizational and, consequently, systemic implications require research. This study examines how interaction barriers among universities, industry, and government, stemming from intra-organizational cultures, impact structural change in the innovation system of Azerbaijan. Utilizing the TH model, interviews with 59 participants revealed that a "Statist" TH model in Azerbaijan hinders organic cultural development within organizations, leading to interaction issues among TH actors. Moreover, problems in inter-organizational communication pave the way for a systemic failure that necessitates government intervention, strengthening the "Statist" TH model. The findings increase the context sensitivity of the TH framework by exploring an understudied context and provide valuable insights relevant to other transition economies facing similar institutional legacies.

Identifying pigments from colored relics is essential for their color restoration and for facsimile creation. A workflow for identifying pigment information is constructed based on visible spectral imaging technology, aligned with the drawing process of colored relics. This workflow includes three steps: boundary extraction, material identification and prediction of mixture proportions. The methods for segmenting visible spectral images, identifying chemical compositions, and predicting mixture proportions of pigments are extensively reviewed. Future research trends of these methods are also analyzed. The influence of the pigment particle size is currently underexplored but can be accomplished by multidisciplinary research.

The Daitokuji Old Collection's 500 Luohans Paintings 五百羅漢圖, painted by Southern Song Mingzhou 明州 artists Lin Tinggui 林庭珪 and Zhou Jichang 周季常, have become a focal point in recent studies on the Chinese Buddhist material culture of the Song Dynasty. Among the 500 Luohans series, five paintings are related to the ancient Indian legend of Emperor Aśoka's creation of 84,000 stupas. These paintings include "Building a Stupa" (No.78), "King Aśoka Stupa Emitting Light" (No.79), "Precious Stupa on the Rock" (No.80), and "Miracle of Light-Emitting Relics" (No.81), which are currently housed in the Daitokuji 大德寺 in Kyoto, Japan, and "Luohans Watching the Relics' Light" (B5), which is housed in the Museum of Fine Arts in Boston, the US. However, the way in which the "King Aśoka Stupa" 阿育王塔 and "Relics' Light" 舍利光 series were integrated into the overall visual narrative of the 500 Luohans in the Daitokuji and Boston collections, as well as the profound meanings and social-cultural contexts embedded in these images, have been rarely studied in depth. The introduction of the miraculous relics theme into the Daitokuji Old Collection's 500 Luohans Paintings originates from an earlier version by the monk Fa Neng. However, Fa Neng's version recorded by the Northern Song literati Qin Guan 秦觀 does not mention the King Aśoka Stupa. The artists had considerable freedom in depicting miraculous relic phenomena and King Aśoka Stupa. The specific details of King Aśoka Stupa's background in Tiantai Mountain 天台山, such as rock bridges, waterfalls, and rock caves, as well as the craftsmanship of King Aśoka Stupa, reflect particular contemporary ideas. The vivid depictions of the "King Aśoka Stupa" and "Relics' Light" in the Daitokuji Present Collection and the Boston Collection of the 500 Luohans may indicate a close connection between the creation of these images and the fervent Relics Worship at King Aśoka Temple 阿育王寺 in Mingzhou during Southern Song. This paper synthesizes these images, ancient Chinese and Japanese manuscripts, and fieldwork insights to interpret the sources and significance of these images. [ABSTRACT FROM AUTHOR]

In recent years, with the development of 3D digitization of cultural relics, most cultural sites contain a large number of fine 3D data of cultural relics, especially complex geometric objects such as painted cultural relics. At present, how to automatically extract surface damage information from the fine 3D color model of painted cultural relics and avoid the loss of accuracy caused by reducing the dimension using conventional methods is an urgentproblem. In view of the above issues, this paper proposes an automatic and high-precision extraction method for cultural relics surface shedding diseases based on 3D fine data. First, this paper designs a 2D and 3D integrated data conversion model based on OpenSceneGraph, a 3D engine, which performs mutual conversion between 3D color model textures and 2D images. Second, this paper proposes a simple linear iterative clustering segmentation algorithm with an adaptive k value, which solves the problem of setting the superpixel k value and improves the accuracy of image segmentation. Finally, through the 2D and 3D integrated models, the disease is statistically analyzed and labeled on the 3D model. Experiments show that for painted plastic objects with complex surfaces, the disease extraction method based on the 3D fine model proposed in this paper has improved geometric accuracy compared with the current popular orthophoto extraction method, and the disease investigation is more comprehensive. Compared with the current 3D manual extraction method in commercial software, this method greatly improves the efficiency of disease extraction while ensuring extraction accuracy. The research method of this paper activates many existing 3D fine data of cultural protection units and converts conventional 2D data mining and analysis into 3D, which is more in line with the scientific utilization of data in terms of accuracy and efficiency and has certain scientific research value, leading value and practical significance.

In 1606 Henry Garnet, provincial of the English Jesuits and purported co-conspirator in the Gunpowder Plot against James I, was executed at St. Paul's Cathedral in London. Following his death, accounts of miracles occurring at his execution began to spread throughout England, including an account of a relic bearing his miraculous image. While Catholic writers promoted these accounts as evidence of Garnet's innocence, Protestant contemporaries argued that Garnet was an illegitimate martyr and that his commemoration was evidence of Catholic support for regicide. This article demonstrates how London Protestant writers and publishers utilized anti-hagiographical arguments to intervene in attempts to promote Garnet's sainthood, counter claims about the veracity of his relic, and shape his legacy in the decades following his execution.

Bronze artifacts often suffer from "bronze disease" due to the presence of chloride ions, which result from copper chlorides forming on their surfaces during storage. Therefore, reinforced protection is essential for these unearthed cultural artifacts, and new materials for the reinforced protection of fragile bronzes are urgently needed. In this study, cuprammonium solvent and nanocellulose (CNC) were utilized as reinforcement materials to protect fragile bronzes. The chemical and aesthetic properties before and after reinforcement were analyzed using ultra-depth field microscopes, SEM-EDX, XRD, and Raman spectroscopy. The results indicated that at a nano-cuprammonium reinforcer concentration of 2.5 mol/L, the optimal reinforcement effect on simulated bronze powdery rust samples was achieved.Mechanical strength increased by an average of 77.59%. The mass growth rate reached 84.8%, while the color difference Δ E remained below 4.0. Additionally, aging resistance significantly improved, aligning with cultural artifact protection standards.Meanwhile, a compact and stable protective membrane formed on the surface of the bronzes, isolating the bronze matrix from direct contact with the external environment, which delayed bronze corrosion and contributed to long-term stable preservation.

The museum system is exposed to a high risk of seismic hazards. However, it is difficult to carry out seismic hazard prevention to protect cultural relics in collections due to the lack of real data and diverse types of seismic hazards. To address this problem, we developed a deep-learning-based multi-source feature-fusion method to assess the data on seismic damage caused by collected cultural relics. Firstly, a multi-source data-processing strategy was developed according to the needs of seismic impact analysis of the cultural relics in the collection, and a seismic event-ontology model of cultural relics was constructed. Additionally, a seismic damage data-classification acquisition method and empirical calculation model were designed. Secondly, we proposed a deep learning-based multi-source feature-fusion matching method for cultural relics. By constructing a damage state assessment model of cultural relics using superpixel map convolutional fusion and an automatic data-matching model, the quality and processing efficiency of seismic damage data of the cultural relics in the collection were improved. Finally, we formed a dataset oriented to the seismic damage risk analysis of the cultural relics in the collection. The experimental results show that the accuracy of this method reaches 93.6%, and the accuracy of cultural relics label matching is as high as 82.6% compared with many kinds of earthquake damage state assessment models. This method can provide more accurate and efficient data support, along with a scientific basis for subsequent research on the impact analysis of seismic damage to cultural relics in collections.

We present the serendipitous discovery of (1) a large double radio relic associated with the galaxy cluster PSZ2 G277.93 + 12.34 and (2) a new odd radio circle, ORC J1027–4422, both found in the same deep MeerKAT 1.3 GHz wide-band radio continuum image. The angular separation of the two arc-shaped cluster relics is ∼16 arcmin or ∼2.6 Mpc for a cluster redshift of z ≈ 0.158. The thin southern relic, which shows several ridges/shocks including one possibly moving inwards, has a linear extent of ∼1.64 Mpc. In contrast, the northern relic is about twice as wide, twice as bright, but only has a largest linear size of ∼0.66 Mpc. Complementary SRG/eROSITA X-ray images reveal extended emission from hot intracluster gas between the two relics and around the narrow-angle tail (NAT) radio galaxy PMN J1033–4335 (z ≈ 0.153) located just east of the northern relic. The radio morphologies of the NAT galaxy and the northern relic, which are also detected with the Australian Square Kilometer Array Pathfinder (ASKAP) at 888 MHz, suggest both are moving in the same outward direction. The discovery of ORC J1027–4422 in a different part of the same MeerKAT image makes it the fourth known single ORC. It has a diameter of ∼90 arcsec corresponding to 400 kpc at a tentative redshift of z ≈ 0.3 and remains undetected in X-ray emission. Supported by simulations, we discuss similarities between outward moving galaxy and cluster merger shocks as the formation mechanisms for ORCs and radio relics, respectively. [ABSTRACT FROM AUTHOR]

In recent years, the demand for the protection and restoration of cultural heritage has become increasingly urgent. Particularly for paper-based cultural relics such as ancient books and paintings, their restoration is especially important due to their unique nature and susceptibility to environmental damage. Among various restoration materials, calcium hydroxide (Ca(OH)2) has been widely studied and applied in the protection of paper-based cultural relics. However, commercial Ca(OH)2 materials have issues such as a large particle size and slow carbonation. In order to address these issues, this study employed carboxymethyl cellulose (CMC) as a support, on which nano-sized Ca(OH)2 crystals were grown in situ on its surface, followed by loading with TiO2 nanoparticles, successfully preparing a multifunctional paper-based cultural relic restoration material with reinforcement, deacidification, anti-aging, and antimicrobial properties. It is worth noting that by in situ growing Ca(OH)2 on the surface of CMC, particle size control, uniform dispersion, and the fixation of Ca(OH)2 can be achieved. CMC is used to enhance the mechanical strength of the paper, Ca(OH)2 is used for deacidification, and TiO2 is used for anti-aging and antimicrobial purposes. This study provides a new approach and method for the restoration of paper-based cultural relics, simplifying traditional multi-step processes and avoiding potential impacts on the cultural relics from multiple repairs.

The INSPIRE project has built the largest sample of ultra-compact massive galaxies (UCMGs) at 0.1 < z < 0.4 and obtained their star formation histories (SFHs). Due to their preserved very old stellar populations, relics are the perfect systems to constrain the earliest epochs of mass assembly in the Universe and the formation of massive early-type galaxies. The goal of this work is to investigate whether a correlation exists between the degree of relicness (DoR), quantifying the fraction of stellar mass formed at z > 2, and the other stellar population parameters. We use the Full-Index-Fitting method to fit the INSPIRE spectra to single stellar population (SSP) models. This allows us to measure, for the first time, the slope of the IMF, as well as stellar metallicity [M/H], [Mg/Fe], [Ti/Fe], and [Na/Fe] ratios, and study correlations between them and the DoR. Similarly to normal-sized galaxies, UCMGs with larger stellar masses have overall higher metallicities. We found a correlation between the IMF slope and the DoR, that, however, breaks down for systems with a more extended SFH. An even stronger dependency is found between the IMF and the fraction of mass formed at high- z. At equal velocity dispersion and metallicity, galaxies with a higher DoR have a larger dwarf-to-giant ratio, i.e. a bottom heavy IMF, than that of low-DoR counterparts. This might indicate that the cosmic epoch and therefore different formation scenarios influence the fragmentation of the star formation cloud and hence might be the explanation for IMF variations detected in massive ETGs.

Gypsification is a common problem in weathered calcareous relics. In previous studies, the solutions of barium hydroxide in water and methanol were used as protectants for gypsification calcareous relics and showed significant differences in permeability. In this study, the underlying reasons for permeability differences between these two solutions were investigated using optical microscopy, ultraviolet–visible spectrophotometry, X-ray diffractometry, Fourier transform infrared spectroscopy, the phenolphthalein test and physical property characterizations. The results indicated that the permeability differences were primarily caused by the solutions' reactivity. Specifically, owing to the high reactivity of barium hydroxide in water, it reacted rapidly with atmospheric CO2 and gypsum (the weathering product) to generate barium carbonate, barium sulfate and calcium hydroxide precipitates. These precipitates hindered the penetration of solution into weathered relics. In contrast, barium hydroxide in methanol did not react with atmospheric CO2 or weathered relics, which also kept the solution in a liquid state during the infiltration process. Therefore, the solution of barium hydroxide in methanol exhibited high permeability. Based on the above findings, this study is meaningful for applying barium protectants in the conservation of gypsification calcareous relics. [ABSTRACT FROM AUTHOR]

Liturgy was the perfect and unparalleled medium for public relations in the Middle Ages, and when it came to relics, it could transform any stone, bone, or a piece of wood into an object worthy of devotion. This article revolves around the activating force of the relics of Mary Magdalene in medieval France. It examines two liturgies—from Vézelay and from Saint-Maximin in Provence—honouring the saint, representing two distinct responses whose character reflects the priorities of the communities that produced them and the agendas that set them in motion. Liturgy was accorded a special role in bolstering the claims of Provence over the corporeal presence of Mary Magdalene in its midst, with liturgists adopting a more audacious and unreserved vocabulary to validate these claims over those of Vézelay.

Most Udmurt living in the Bashkortostan Republic and in the Perm' region of the Russian Federation are followers of a traditional ethnic religion. In their spiritual life, a huge place is occupied by sanctuaries and other places in which their ritual practices take place, such as the worship of deities, spirits and ancestors. We can identify different types of such places in this Udmurt regional group: the sanctuary dedicated to the cult of the clan protector deities, groves dedicated to the god Lud, places dedicated to personal and family cults, sacred places of agrarian sacrifices, territories where funerary and commemorative rituals take place, places dedicated to the propitiation of evil spirits. Depending on their social status, the sanctuaries are regional or general and can be related to a family, clan, village, or multiple villages. In this article, which relies on the authors' ethnographic fieldwork and published sources, we analyse the present state of the sacred places. We show that the transformation of cultural patterns has led some types of sanctuary to cease functioning, while others have remained as relics and the places of agrarian sacrifices have undergone an active revitalisation.

Abstract The rise in sea levels, driven by global climate change, poses a significant threat to cultural heritage in coastal regions. Traditional risk assessment methods, focusing on direct inundation, often fail to consider the crucial impact of socio-economic factors, which are significantly vulnerable to sea level rise. To bridge this gap, this study introduces an innovative Sea Level Rise Cultural Heritage Impact Assessment Model (SLR-CHIA Model), a novel approach that integrates both land inundation and socio-economic aspects. This comprehensive model evaluates potential risks to various types of cultural heritage in coastal China, including intangible cultural heritage, relics, and traditional villages. The study’s findings are striking: (1) About 7.79% of coastal villages, 53.94% of relics, and 2.53% of intangible cultural heritage are potentially at high risk in a 100-year sea level rise event; (2) Relics in the Eastern coast and villages in the Southern coast are most vulnerable; (3) Different types of cultural heritage rely on diverse principal factors for protection, resulting in varied risk levels under sea level rise conditions. The SLR-CHIA Model provides a vital methodological framework for evaluating cultural heritage risks in other global regions.

Ancient glass products have suffered from the baptism of time and experienced changes in the burial environment and weathering, resulting in a change in the proportions of their chemical composition and interfering with their accurate identification by later generations. In this paper, the chemical composition of ancient glass products is predicted and identified. First, the multivariate statistical ANOVA test is applied to explore the relationship between whether the cultural relics samples are weathered or not and the glass type, decoration, and color to derive a law of chemical composition of the cultural relics and to analyze the correlation and difference among the four factors. Second, compared with the relevant data of the existing glass products, the missing values are processed by using the method of filling in the plurality. The weathering condition of the sampling points of the samples whose surfaces are not weathered is judged by the "distance discrimination method." Combined with the characteristics of the lead-barium glass and the high-potassium glass, the law of the chemical composition content on the surface of the samples, weathered or not, is explored. The modeling of the gray prediction method was applied again to predict the chemical composition content before weathering. Finally, the generalized Shapley function of fuzzy measurement was used to analyze the correlation between indicators and the chemical compositions and their differences. The scheme proposed in this paper can solve the difficult problem of category judgment in archeology, which is of great significance in promoting the smooth progress of archaeological work.

Salt efflorescence is one of the critical problems for the preservation of immovable silicate relics. Salt efflorescence mainly comes from continuous cycles of crystallization/dissolution or hydration/dehydration of salts in confined pores in silicate relics. Many protocols have been developed in attempts to alleviate possible salt damages with minor success because of endless water and salt feed from underground. In this study, we propose and design a novel technique for salt damage prevention and protection of immovable relics. Materials with higher water-absorbing ability than matrix are applied to control the water and salt migration direction in simulated sand samples. The distribution of moisture content on the surface of sand is followed by hyperspectral imaging. It appears that water and salt molecules will preferentially transport towards positions containing higher water-absorbing material. Both organic and inorganic high water-absorbing materials show effective in controlling the water and salt migration direction, which provides a new approach for the prevention and protection of salt efflorescence in silicate cultural relics.

Purpose: Paper-based artifacts hold significant cultural and social values. However, paper is intrinsically fragile to microorganisms, such as mold, due to its cellulose composition, which can serve as a microorganisms' nutrient source. Mold not only can damage papers' structural integrity and pose significant challenges to conservation works but also may subject individuals attending the contaminated artifacts to health risks. Current approaches for strain identification usually require extensive training, prolonged time for analysis, expensive operation costs, and higher risks of secondary damage due to sampling. Thus, in current conservation practices with mold-contaminated artifacts, little pre-screening or strain identification was performed before mold removal, and the cleaning techniques are usually broad-spectrum rather than strain-specific. With deep learning showing promising applications across various domains, this study investigated the feasibility of using a convolutional neural network (CNN) for fast in-situ recognition and classification of mold on paper. Methods: Molds were first non-invasively sampled from ancient Xuan Paper-based Chinese books from the Qing and Ming dynasties. Strains were identified using molecular biology methods and the four most prevalent strains were inoculated on Xuan paper to create mockups for image collection. Microscopic images of the molds as well as their stains situated on paper were collected using a compound microscope and commercial microscope lens for cell phone cameras, which were then used for training CNN models with a transfer learning scheme to perform the classification of mold. To enable involvement and contribution from the research community, a web interface that actuates the process while providing interactive features for users to learn about the information of the classified strain was constructed. Moreover, a feedback functionality in the web interface was embedded for catching potential classification errors, adding additional training images, or introducing new strains, all to refine the generalizability and robustness of the model. Results & Conclusion: In the study, we have constructed a suite of high-confidence classification CNN models for the diagnostic process for mold contamination in conservation. At the same time, a web interface was constructed that allows recurrently refining the model with human feedback through engaging the research community. Overall, the proposed framework opens new avenues for effective and timely identification of mold, thus enabling proactive and targeted mold remediation strategies in conservation.

It is very important to reveal the weathering characteristics of stone cultural relics to protect their integrity for a long time. Infrared thermal imaging was employed in this study to analyze the degree of weathering and classification of stone cultural relics for the protection of the cultural relics. To explore the feasibility of evaluating the overall weathering degree of rock surface, the weathering degree of the rock surface was first determined by using various conventional testing methods. Then, the weathering degree of rock surface was quantified by applying infrared thermal imaging. Finally, the weathering degree of the rock surface was analyzed by comparing it with conventional testing results. Results show that, the infrared thermal imaging can distinguish general disease types and degrees of development based on abnormal surface temperature. When the surface weathering of stone cultural relics is more serious, the temperature change at a certain time is greater after water spraying and cooling. The conclusions obtained in this study can provide a reference for evaluating the overall weathering degree of the surface layer of stone cultural relics via infrared thermal imaging.

This article describes the history of a medieval English True Cross relic, known as the Holy Rood of Bromholm, supposedly acquired from Constantinople by an English cleric during the Fourth Crusade. It compares the English monastic accounts of the Holy Rood's translation with accounts of the Fourth Crusade and its aftermath to explore the biography of the English cleric who gave the relic to Bromholm Priory and determine the historicity of his account. However, in exploring the supposed origins of the Bromholm Cross, this article demonstrates that not only can it not be the relic it claims to be, because that relic continued to be used in Constantinople after its supposed departure for England, but points out that the descriptions and artistic depictions of the Bromholm Cross match a very different True Cross relic from Constantinople than the relic it purports to be - thus proving it to be a forgery.

Tetraethoxysilane (TEOS) is the most commonly used silicon-based reinforcement agent for conserving art relics due to its cost-effectiveness and commercial maturity. However, the resulting silica gel phase is prone to developing cracks as the gel shrinks during the sol–gel process, potentially causing severe damage to the objects being treated. In this study, dodecyltrimethoxysilane (DTMS) was introduced into TEOS to minimize this shrinkage by adding elastic long chains to weaken the capillary forces. The gel formed from the DTMS/TEOS hybrid material was transparent and crack-free, featuring a dense microstructure without mesopores or micropores. It exhibited excellent thermal stability, with a glass transition temperature of up to 109.64 °C. Evaluation experiments were conducted on artificially aged, handmade bamboo paper. The TEOS-based hybrid material effectively combined with the paper fibers through the sol–gel process, polymerizing into a network structure that enveloped the paper surface or penetrated between the fibers. The surface of the treated paper displayed excellent hydrophobic properties, with no significant changes in appearance, color, or air permeability. The mechanical properties of the treated bamboo paper improved significantly, with longitudinal and transverse tensile strengths increasing by up to 36.63% and 44.25%, respectively. These research findings demonstrate the promising potential for the application of DTMS/TEOS hybrid materials in reinforcing paper relics. [ABSTRACT FROM AUTHOR]

Significant variations in climate exist between the northern and southern regions of China, resulting in varying degrees of decay observed in wooden relics unearthed from different areas. The preservation of wooden cultural artifacts in humid environments is influenced by numerous factors including regional environmental conditions (such as temperature, humidity, and biological mold), and site structural characteristics, among others, making the conservation efforts more specialized and intricate. This study utilizes the example of the unearthed wet outer coffin wooden cultural relics from the Tomb of Marquis Yi of Zeng to demonstrate a method involving the use of polyvinyl acetate (PVAc) composite material for the reinforcement and protection of such artifacts. Through a comprehensive analysis of various analytical techniques including scanning electron microscopy, Fourier transform infrared spectroscopy (FT-IR), density increase rate, wood compression strength along the grain, hydrophobic property, and other micro and macro properties, it was determined that: The combination of PVAc and shellac as a reinforcement agent has been shown to enhance the mechanical properties of wooden cultural relics while also maintaining minimal color variation, increased biocompatibility, and durability. This method is particularly well-suited for fortifying and preserving damp wooden cultural relics that exhibit varying degrees of decay. The findings offer significant insights and potential avenues for further research on the preservation methods for large wooden cultural artifacts discovered in the middle and lower regions of the Yangtze River dating back to the Warring States Period.

In the acquisition process of 3D cultural relics, it is common to encounter noise. To facilitate the generation of high-quality 3D models, we propose an approach based on graph signal processing that combines color and geometric features to denoise the point cloud. We divide the 3D point cloud into patches based on self-similarity theory and create an appropriate underlying graph with a Markov property. The features of the vertices in the graph are represented using 3D coordinates, normal vectors, and color. We formulate the point cloud denoising problem as a maximum a posteriori (MAP) estimation problem and use a graph Laplacian regularization (GLR) prior to identifying the most probable noise-free point cloud. In the denoising process, we moderately simplify the 3D point to reduce the running time of the denoising algorithm. The experimental results demonstrate that our proposed approach outperforms five competing methods in both subjective and objective assessments. It requires fewer iterations and exhibits strong robustness, effectively removing noise from the surface of cultural relic point clouds while preserving fine-scale 3D features such as texture and ornamentation. This results in more realistic 3D representations of cultural relics. [ABSTRACT FROM AUTHOR]

Compact massive relic galaxies are a class of galaxies that exhibit characteristics suggesting they have remained largely unchanged since their initial formation, making them 'relics' of the early Universe. These galaxies represent a distinct class characterized by strongly peaked high-velocity dispersion profiles with large rotational velocities. This study investigates the formation of such galaxies within the framework of Milgromian dynamics (MOND), offering a unique perspective on their origin without invoking the presence of cold or warm dark matter. Our analysis focuses on the collapse dynamics of isolated non-rotating post-big bang gas clouds, revealing kinematic and density profiles comparable to observed compact massive relic galaxies like NGC 1277, Mrk 1216, and PGC 032873. The findings underscore the natural emergence of compact massive relic galaxies within a MOND-based Universe, providing valuable insights into the interplay between gravitational dynamics and galaxy formation.

To develop an environment‐friendly detergent for textile relics adsorbing soil/rust stains, the relationship between surfactant types and concentrations, the nature of additives and the type of textile (e.g., cotton, linen, silk or wool) were systematically investigated. Results showed that the detergent formulations of sodium montmorillonite (5 g/L) as additives were overall the best options for soil stains removal on textile relics. Specifically, the most suitable surfactant for cotton, linen, silk and wool textiles relics adsorbing soil stains was rhamnolipid (8 g/L), tea saponin (6 g/L), tea saponin (8 g/L), alkyl glycosides (10 g/L), respectively. The detergent formulations of ascorbic acid (5 g/L) as additives were more beneficial for rust stains peeling‐off from the surface of the textile relics regardless of the type of surfactant and textile relics. But the optimal surfactants for different textiles relics were different. In detail, the most suitable surfactants for cotton, linen, silk and wool textiles relics adsorbing rust stains were separately rhamnolipid (10 g/L), Tea saponin (8 g/L), Tea saponin (6 g/L), Alkyl glycosides (6 g/L). This indicated that the washing effect of detergent formulation was related to the types of stains and textile relics' fiber. These findings not only demonstrated the necessity for developing detergent formulations for different textile relics, but also illustrated the complexity and diversity of the textile relics' stain‐washing work. Moreover, this work also assists understanding of the washing mechanism of textile relics and help the department of textile relics protection to properly wash textile relics and extend the life of textile relics.

This article offers a pedagogical approach to introducing undergraduate students to hagiology by comparing medieval sanctity to modern celebrity. The bodies of saints and celebrities are important loci for the transmission of sanctity or celebrity from a person to the public and for the continuity of identity. Examples include St. Faith, St. Cuthbert, Kim Kardashian, and Marilyn Monroe. Using a comparative method allows students who are non-religious to better apprehend the unfamiliar practices and beliefs around the cult of saints and relics. [ABSTRACT FROM AUTHOR]

Natural disaster risk monitoring is an important task for disaster prevention and reduction. In the case of immovable cultural relics, however, the feedback mechanism, risk factors, monitoring logic, and monitoring indicators of natural disaster risk monitoring are complex. How to achieve intelligent perception and monitoring of natural disaster risk for immovable cultural relics has always been a focus and a challenge for researchers. Based on the analysis of the concepts and issues related to the natural disaster risk of immovable cultural relics, this paper proposes a framework for natural disaster risk monitoring for immovable cultural relics based on the digital twin. This framework focuses on risk monitoring, including the physical entities of natural disaster risk for immovable cultural relics, monitoring indicators, and virtual entity construction. A platform for monitoring the natural disaster risk of immovable cultural relics is proposed. Using the Puzhou Ancient City Site as a test bed, the proposed concept can be used for monitoring the natural disaster risk of immovable cultural relics at different scales. [ABSTRACT FROM AUTHOR]

Cultural relics line graphic serves as a crucial form of traditional artifact information documentation, which is a simple and intuitive product with low cost of displaying compared with 3D models. Dimensionality reduction is undoubtedly necessary for line drawings. However, most existing methods for artifact drawing rely on the principles of orthographic projection that always cannot avoid angle occlusion and data overlapping while the surface of cultural relics is complex. Therefore, conformal mapping was introduced as a dimensionality reduction way to compensate for the limitation of orthographic projection. Based on the given criteria for assessing surface complexity, this paper proposed a three-dimensional feature guideline extraction method for complex cultural relic surfaces. A 2D and 3D combined factor that measured the importance of points on describing surface features, vertex weight, was designed. Then the selection threshold for feature guideline extraction was determined based on the differences between vertex weight and shape index distributions. The feasibility and stability were verified through experiments conducted on real cultural relic surface data. Results demonstrated the ability of the method to address the challenges associated with the automatic generation of line drawings for complex surfaces. The extraction method and the obtained results will be useful for line graphic drawing, displaying and propaganda of cultural relics. [ABSTRACT FROM AUTHOR]

Burial stone relics remain in a humid, semi-enclosed environment for long periods, and temperature and humidity variations can cause deterioration acceleration. Yang Can's tomb was selected as the research object, and field monitoring and simulations were performed to investigate the characteristics of temperature and humidity variations, after which the simulation results were evaluated. The monitoring results showed that solar radiation, rainfall, wind speed, and depth of entry are important factors affecting the variation in the temperature and humidity of burial stone relics. The temperature outside the chamber is greatly affected by seasonal variations, while the humidity inside the chamber is influenced by seasonal variations, so appropriate measures should be implemented inside and outside the chamber during different seasons to alleviate deterioration. On the basis of the above analysis, a temperature and humidity model for the interior chamber of burial stone relics was established in COMSOL software 5.6, combined with a porous medium heat transfer model and computational fluid dynamics (CFD) model. The temperature and humidity inside the chamber can be calculated by the temperature and humidity outside the chamber. This study provides data support for hydrothermal, condensation and other related studies of burial stone relics. [ABSTRACT FROM AUTHOR]

Looking at examples of the suffering of Orthodox Christians starting from the early Christian up to the modern period, the same elements of martyrological causes and circumstances as well as the character of martyr cults and, later, miracle-working of relics can be observed. Based on this, common hagiographic topos were defined: emphasis on physical beauty, perseverance in faith, cruel torture, the way of establishing the cult and the story of miracle-working. The fact that the martyrological context based on theology, defined in the early Christian period, directly refers to the cults of the new martyrs, especially from the area of Kosovo and Metohija, precisely indicates the continuity of martyrdom for the faith. In such a discourse, the examples of the Kosovo-Metohija new martyrs Grigorije Pećki, Vasilije Pekar and Bosiljka Pasjanska represent not only a link but also a confirmation of the New Testament announcement that there will be suffering for Christ until His second coming, which is also proven by the latest examples of the venerable martyrs of Kosovo-Metohija Hariton and Stefan.

Relic galaxies are massive, compact, and quiescent objects observed in the local Universe that have not experienced any significant interaction episodes or merger events since about z  = 2, remaining relatively unaltered since their formation. On the other hand, massive and compact early-type galaxies (cETGs) in the local Universe appear to show similar properties to Relic galaxies, despite having substantial accretion history. Relic galaxies, with frozen history, can provide important clues about the intrinsic processes related to the evolutionary pathways of ETGs and the role that mergers play in their evolution. Using the high-resolution cosmological simulation TNG50-1 from IllustrisTNG project, we investigate the assembly history of a sample of massive, compact, old, and quiescent subhaloes split by satellite accretion fraction. We compare the evolutionary pathways at three cosmic epochs: z  = 2, z  = 1.5, and z  = 0, using the orbital decomposition numerical method to investigate the stellar dynamics of each galactic kinematical component and their environmental correlations. Our results point to a steady pathway across time that is not strongly dependent on the mergers or the environment. Relics and cETGs do not show a clear preference for high- or low-density environments within the volume explored at z  = 0, as they are found in both scenarios. However, the progenitors of Relic galaxies have consistently resided in high-density environments since z  = 2, while cETGs were shifted to such environments at a later stage. The merger history can be recovered from the stellar kinematics imprints in the local Universe. Relics and cETGs show consistently dynamical similarities at z  = 2 and differences at z  = 0 to disc, bulge, and hot inner stellar halo. In the current scenario, the mergers that drive the growth of cETGs do not give rise to a new and distinct evolutionary pathway when compared to Relics. [ABSTRACT FROM AUTHOR]

We report the discovery of a radio relic in the north-eastern periphery of the galaxy cluster Abell 2108 (A2108). A2108 is part of the uGMRT LOw-MAss Galaxy Cluster Survey (GLOMACS), where our main aim is to search for diffuse radio emission signatures in very sparsely explored low-mass galaxy clusters using uGMRT band-3 (central frequency 400 MHz). We used our uGMRT band-3 observations along with the existing archival band-3 uGMRT data to improve image sensitivity. Along with the previously reported south-western relic, the discovery of the new relic makes A2108 one of the few low-mass clusters hosting a double relic. The new relic spans over a region of 610 kpc × 310 kpc and, interestingly, differs considerably in size and morphology from the other relic. Using XMM–Newton science archive data, we also report the tentative detection of a mildly supersonic shock of Mach number |$\mathcal {M}_\mathrm{SB}=1.42$| and |$\mathcal {M}_\mathrm{T} = 1.43$| from the surface brightness and temperature discontinuities, respectively, near this newly found relic. Both the relics in A2108 are found to be significantly under-luminous compared with other double-relic systems in the mass–luminosity plane. Moreover, the north-eastern relic is remarkably under-luminous in the size–luminosity plane. Although mild supersonic shocks resulting from an off-axis merger could have influenced the origin of both relics, we hypothesize that local environments have played a crucial role in shaping their morphologies.

Geological relics are one of the important components of geoscience culture, so studies on their distribution characteristics and genesis are helpful to the effective investigation and evaluation of the landscape resources in geological relics. Zhaotong City is located on the southeastern margin of the Tibetan Plateau in the northeastern Yunnan Province of Southwest China. It belongs to the Yangtze plate of South China, which is located at the southwest edge of the Yangtze block-a secondary tectonic unit within the plate. The formation and distribution of landscapes of geological relics in Zhaoyang district are closely related to the formation and evolution of the Zhaotong intermountain basin. On the basis of detailed field investigations of geological relics, this study comprehensively classifies and analyzes the genesis of various geological relics in Zhaoyang district of Zhaotong City in northeastern Yunnan Province. The strata in the Zhaoyang area are fully exposed, ranging from the Cambrian Meishucun Formation (Zhongyicun member of Dengying Formation) to the Quaternary system (Neogene). The Cambrian and Ordovician systems are mainly exposed in Yanshan township and Dazhaizi township by the Jinsha river, and are mainly buried deep underground in other areas. The Meishucun Formation at the bottom of the Cambrian is a phosphate-bearing rock series, with the upper Qiongzhusi Formation and Canglangpu Formation being a combination of terrigenous sandstone and mudstone. The Longwangmiao Formation to the Erdaoshui Formation and the Ordovician Formation at the top of the lower Cambrian are mostly composed of carbonate rocks. Meishucun Formation at the bottom of the Cambrian is composed of the phosphorus-bearing rock series. The upper Qiongzhusi Formation and Canglangpu Formation are the combination of terrigenous sand and mudstone. The top of the lower Cambrian Longwangmiao Formation to the Erdaoshui Formation and the Ordovician are mostly composed of carbonate rocks. The combination of terrigenous sand and mudstone, accompanied by muddy limestone, is developed in Hong'anpo Formation of the Silurian system to the upper part of middle Devonian. Thick carbonate deposits are developed in Qujing Formation at the top of middle Devonian to the Maokou Formation of the lower Permian. From the Xuanwei Formation at the top of Permian to the Cretaceous, there are only sporadic outcrops-mainly terrigenous sand and mudstone-in Zhaoyang district. The Paleogene mainly consists of sand, mudstone and thick lignite. The bottom of the Neogene is mainly composed of conglomerate with a small amount of limestone and sandstone; the clay soil is interbedded with gravel in the middle part; the grey clay soil is interbedded with siltstone at the bottom. The Quaternary system is filled with swampy sediments of clays, silts, etc. and abundant biological fossils, such as ostracods, stonewort, ichthyodont and viviparus. The results show that the geological relics of Zhaoyang district can be divided into western region and eastern region. The western region is a basalt platform like Dashanbao, including volcanic landform, plateau lakes and wetland. The eastern region takes carbonate rock karst landform of Zhaotong mountain basin as the center by paleontological fossil landscape. The abundant lithology, like carbonate rock, shale, sandstone, basalt and so on, contributes to karst development and karst geomorphology difference. The tectonic landforms formed by different degrees of fault-fold are the main factors of the differentiation of geological relics. Under background of stratigraphic lithology and tectonic geomorphology, hydrologic conditions provide external dynamic factors for abundant geological landscapes. Our research is of great scientific value of geological relics resources in Zhaotong, and also provides a basis for studies on mammal fossils in Late Neogene. It is concluded as follows, (1) Geological relics of Zhaoyang district in Zhaotong City include canyon landform, volcanic landform, karst landform, plateau lake, wetland and fossil landscape, etc., with great value of tourism. (2) Abundant stratigraphic lithology is the basis for the development of different geological relics. Two sets of outcrops of carbonate rocks widely shaped the modern geological landscape with karst landform and water landform in the study area. Vertically, the strata of Zhaoyang district are characterized by an interphase pattern of three sets of water-resisting rock series and two sets of water-bearing rock series, being the geological foundation of geological relics. From the bottom to the top of strata are distributed the water-resisting rock series mainly composed of mudstone from the Cambrian Qiongzhusi Formation to the Canglangpu Formation, the water-bearing rock series composed of carbonate rock and diamictite from the Cambrian Longwangmiao Formation to the Ordovician Daqing Formation, the water-resisting rock series mainly composed of sand and mudstone with marine-terrestrial transitional facies from the Silurian Longmaxi Formation to the Devonian Hongyapo Formation, the water-bearing rock series composed of carbonate rock from the Devonian Qujing Formation to the Permian Maokou Formation, and the water-resisting rock series composed of the Permian Emei basalt. (3) The tectonic process forms a structural pattern of east-west differences in Zhaoyang district, controlling the distribution pattern of geological relics in this district. The reasons are as follows: the Indosinian Movement caused the overall uplift of the northeastern Yunnan into land; the Yanshan movement formed open and gentle folds in the west and relatively tight folds and large-scale faults in the east, resulting in east-west differences; the Xishan movement formed the Zhaotong intermountain basin, caused strong downward erosion of rivers, and controlled the direction of groundwater runoff, becoming a direct controlling factor for the formation of geological relics in Zhaoyang district.

This paper presents the third data release of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 52 ultra-compact massive galaxies (UCMGs) observed with the X-Shooter spectrograph. We measure integrated stellar velocity dispersion, [Mg/Fe] abundances, ages, and metallicities for all the INSPIRE objects. We thus infer star formation histories and confirm the existence of a degree of relicness (DoR), defined in terms of the fraction of stellar mass formed by z  = 2, the time at which a galaxy has assembled 75 per cent of its mass, and the final assembly time. Objects with a high DoR assembled their stellar mass at early epochs, while low-DoR objects show a non-negligible fraction of later formed populations and hence a spread in ages and metallicities. A higher DoR correlates with larger [Mg/Fe], supersolar metallicity, and larger velocity dispersion values. The 52 UMCGs span a large range of DoR from 0.83 to 0.06, with 38 of them having formed more than 75  per cent of their mass by z  = 2. Of these, nine are extreme relics (DoR>0.7), since they formed the totality (⁠|$\gt 99~{{\ \rm per\ cent}}$|⁠) of their stellar mass by redshift z  = 2. The remaining 14 UCMGs cannot be considered relics, as they are characterized by more extended star formation histories. With INSPIRE  we built the first sizeable sample of relics outside the local Universe, up to z ∼ 0.4, increasing the number of confirmed relics by a factor of >10, and opening up an important window to explain the mass assembly of massive galaxies in the high- z Universe.

Semi-exposed relics within an air–soil system often have earthworks partially buried, leading to moisture migration and substantial salt accumulation. Salt accumulation threatens relic preservation, but destructive sampling is hindered by conservation concerns. We conducted a case study on salt enrichment at K9901 Armour Pit of Emperor Qinshihuang 's Mausoleum Site Museum. Environmental factors and soil salt characteristics were assessed through sampling and monitoring. A relic-soil coupling system was established with a soil column device containing burned bricks. Using 5-TE sensors, water and salinity movement was tracked, and X-ray diffraction analyzed relic salt crystals. The soil column experiment effectively simulated water-salt migration in relics. Salts, like Cl−, NO3−, SO42−, Na+, and Mg2+, concentrated on the soil surface during evaporation. Simulation linked specific salt species to relic ailments. Salt solution from soil migrated to bricks, forming CaSO4 crystals. Results highlight coupling's role in salt-related deterioration and the need to protect it for optimal relic preservation. Findings impact semi-exposed relic conservation, revealing salt accumulation processes and their impact on historical artifacts. [ABSTRACT FROM AUTHOR]

The Cathedral of Valencia, Spain, has preserved the so-called Holy Chalice of the Last Supper since 1437. It consists of a foot, a gold stem, and an upper cup carved in agate stone. Based on a pious tradition, this cup is supposed to be the one used by Jesus of Nazareth to institute the Eucharist. According to an archeological study published in 1960, this agate bowl was crafted around the 2nd–1st centuries BC, but people visiting this famous relic often wonder about its authenticity and about the evidence supporting it as a Hellenistic–Roman cup. Attempting to clarify this concern, a photographical characterization of the agate cup is presented and discussed. The main conclusions are the following: (i) The typology of the bowl is common to classical tableware, but the wall thickness, shape of the rim, and foot are typical of gemstone cups from the Hellenistic–Roman period. (ii) This cup would have been extremely valuable, which agrees with the location of the Cenacle in the aristocratic neighborhood of Jerusalem. This case study highlights the importance of further investigating the dating of historical objects as a key issue to support their authenticity. [ABSTRACT FROM AUTHOR]

A joint hadronic model is shown to quantitatively explain the observations of diffuse radio emission from galaxy clusters in the form of minihaloes, giant haloes, relics, and their hybrid, transitional stages. Cosmic-ray diffusion of order D ∼ 1031–32 cm2 s−1, inferred independently from relic energies, the spatial variability of giant-halo spectra, and the spectral evolution of relics, reproduces the observed spatio-spectral distributions, explains the recently discovered mega-haloes as enhanced peripheral magnetization, and quenches electron (re)acceleration by weak shocks or turbulence. For instance, the hard-to-soft evolution along secondary-electron diffusion explains both the soft spectra in most halo peripheries and relic downstreams, and the hard spectra in most halo centres and relic edges, where the photon index can reach α ≃ −0.5 regardless of the Mach number |$\mathcal {M}$| of the coincident shock. Such spatio-spectral modelling, recent γ-ray observations, and additional accumulated evidence are thus shown to support a 2010 claim that the seamless transitions among minihaloes, giant haloes, and relics, their similar energetics, integrated spectra, and delineating discontinuities, the inconsistent |$\mathcal {M}$| inferred from radio versus X-rays in leptonic models, and additional observations, all indicate that these diffuse radio phenomena are manifestations of the same cosmic-ray ion population, with no need to invoke less natural alternatives.

The dynamic relationship that exists between a religious rite and its territory is interpreted and analysed by religious anthropology as a form of protection, offered by the sacred to the place in which it resides. According to this interpretation, passage through the territory of what is reputed to be sacred or even its very presence as a sanctuary, drives evil away and is believed to perform a generally stable protective function. Within such a dynamic, the rite that actually creates this sacred passage, i.e., the procession of relics, lays the foundations for an analysis of the two specific variables that are, in actual fact, intwined: on the one side is the rite, and on the other, the territory. Such a relationship appears all the more problematic due to the progressive rationalisation of the religious dimension, extensively dealt with by Max Weber (Weber 1920) and accepted by contemporary sociology on religion, as it is now a supernatural phenomenon that is only considered to have a representational dimension. The internal secularization at the festival of Saint Rosalia happened in 2023, with the landing of the triumphal cart in New York. The rite moves to another new territory and transforms it. The cart of Saint Rosalia, preserved in the Columbus Citizens Foundation in New York, represents the identity of Sicilian immigrants but also a new form of ritualization on a new territory through an "ancient" ritual. When the sacred is located within the institutional dimension of a salvation religion presided over by an institution, it appears separate from any purely mechanical (and therefore magical) dimension, while the territory becomes a variable in which a multiplicity of factors are contained. These factors not only give importance to the very aspects of the ritual itself, boosting its civil and secular parts, but also to the religious programme, which undergoes unexpected transformations introduced by the presiding institution. The main object of this analysis is, therefore, to establish an interactive path whereby, on the one hand, the territory, through its various cultural components (both secular and religious), shapes the religious rite and how it places restrictions on those protective functions, while on the other, how the rite places its own constraints on the cultural transformations that take place in the fabric of society.

The Main galaxy cluster in the Abell 781 system is undergoing a significant merger and accretion process with peripheral emission to the north and south-eastern flanks of the merging structure. Here we present a full polarimetric study of this field, using radio interferometric data taken at 21 and 92 cm with the Westerbork Synthesis Radio Telescope (WSRT), to a sensitivity better than any 21 cm (L band) observation to date. We detect evidence of extended low-level emission of 1.9 mJy associated with the Main cluster at 21 cm, although this detection necessitates further follow-up by modern instruments due to the limited resolution of the WSRT. Our polarimetric study indicates that, most likely, the peripheral emission associated with this cluster is not a radio relic. [ABSTRACT FROM AUTHOR]

Radio relics are giant sources of diffuse synchrotron radio emission in the outskirts of galaxy clusters that are associated with shocks in the intracluster medium. Still, the origin of relativistic particles that make up relics is not fully understood. For most relics, diffusive shock acceleration (DSA) of thermal electrons is not efficient enough to explain observed radio fluxes. In this paper, we use a magnetohydrodynamic simulation of galaxy clusters in combination with Lagrangian tracers to simulate the formation of radio relics. Using a Fokker–Planck solver to compute the energy spectra of relativistic electrons, we determine the synchrotron emission of the relic. We find that re-acceleration of fossil electrons plays a major role in explaining the synchrotron emission of radio relics. Particles that pass through multiple shocks contribute significantly to the overall luminosity of a radio relic and greatly boost the effective acceleration efficiency. Furthermore, we find that the assumption that the luminosity of a radio relic can be explained with DSA of thermal electrons leads to an overestimate of the acceleration efficiency by a factor of more than 103.
