ABSTRACTDevelopments in non-invasive analytical techniques advance the preservation of cultural heritage materials by identifying and analyzing substrates and media. Spectral imaging systems have been used as a tool for non-invasive characterization of cultural heritage, allowing the collection of chemical identification information about materials without sampling. The Library of Congress has been developing the application of hyperspectral imaging to the preservation and analysis of cultural heritage materials as a powerful, non-contact technique to allow non-invasive characterization of materials, by identifying and characterizing colorants, inks and substrates through their unique spectral response, monitoring deterioration or changes due to exhibit and other environmental conditions, and capturing lost and deteriorated information. The resulting image cube creates a new “digital cultural object” that is related to, but recognized as a distinct entity from the original. The range of data this object contains encourages multidisciplinary collaboration for the integration of preservation, societal and cultural information.

The Impact

Advances in research in Cultural Heritage see increasing application of a multidisciplinary approach and the combined use of physical and chemical characterization of artefacts that can be used to define their structure and their state of conservation, also providing valuable information in selecting the most suitable microclimatic conditions for the exhibition environment. This approach provides a platform for a synergic collaboration amongst researchers, restorers, conservators, and archaeologists. Existing state-of-the-art technologies for neutron-based methods are currently being applied to the study of objects of historical and cultural interest in several neutron-beam facilities around the world. Such techniques are non-invasive and non-destructive and are, therefore, ideal to provide structural information about artefacts, such as their composition, presence of alterations due to the environmental conditions, inclusions, structure of the bulk, manufacturing techniques, and elemental composition, which provide an overall fingerprint of the object’s characteristics, thanks to the nature of the interaction of neutrons with matter. Here, we present an overview of the main neutron methods for the characterization of materials of interest in Cultural Heritage and we provide a brief introduction to the sensors and detectors that are used in this framework. We conclude with some case studies underlining the impact of these applications in different archaeological and historical contexts.

Circuits Vlsi

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.

Key Questions

This paper documents the formulation of an international, interdisciplinary study, on a concerted European level, to prepare an innovative, reliable, independent and global knowledge base facilitating the use of today’s and future optical measuring techniques for the documentation of cultural heritage. Cultural heritage professionals, color engineers and scientists share similar goals for the documentation, curation, long-term preservation and representation of cultural heritage artifacts. Their focus is on accuracy in the digital capture and remediation of artefacts through a range of temporal, spatial and technical constraints. A shared vocabulary to interrogate these shared concerns will transform mutual understanding and facilitate an agreed movement forward in cultural heritage documentation here proposed in the work of the COST Action Color and Space in Cultural Heritage (COSCH). The goal is a model that captures the shared concerns of professionals for a standards-based solution with an organic Linked Data model. The knowledge representation proposed here invokes a GUI interface for non-expert users of capture technologies, facilitates, and formulates their engagement with key questions for the field.

The study of cultural heritage is a multidisciplinary challenge. Working in this area meets a number of peculiarities, which put emphasis on a full study of the elements of the natural environment, as well as the need for brilliant techniques of construction to be used. The detailed studies of the monuments characteristics in a series of engineering areas over the last decade have led us to the conclusion that the creators of these monuments have achieved an important characteristic of their creations – securing their durability. From an engineering standpoint, the examples are valuable in terms of materials as well as the choice of a structural solution as their most important feature. In several sites with world cultural heritage status-the conservation and impact of the monument in the perspective of eternal longevity have been studied, while analyzing construction and the overall vision of the builders to the specific creation. It is these aspects that are the subject of research and it turns out that their role in preserving the monument is extremely important. This publication examines two monuments with extremely distinctive characteristics, requiring complex engineering research and thorough knowledge of natural and anthropogenic materials and their application in the construction techniques of the past. This is an example, and a basis for adequate solutions with an approach for long-term preservation of the structures.

Long Term Preservation

Many studies concur that most of the world’s heritage resources, including digital records, are highly vulnerable to loss, and some cannot be recovered due to neglect or mismanagement. Strategies are thus needed to ensure long-term preservation and global access to digital records of enduring value. Metadata systems have been regarded as a suitable strategy to support digital preservation processes and prevent digital records loss within cultural heritage institutions. The purpose of this paper was to investigate the adoption of metadata systems in cultural heritage institutions in South Africa. This study utilised literature review to critically examine the use of metadata systems for the preservation of digital records in cultural heritage institutions. Although various preservation systems and strategies are being developed to enable description, discovery and delivery of digital records, the findings revealed that South African cultural heritage institutions’ level of metadata system adoption is low. This is due to lack of awareness about metadata schemas and standards, lack of technical expertise, inadequate funding and lack of technological infrastructure. Several recommendations are made to enhance preservation of digital records, including increasing awareness and the implementation of metadata systems, schemas and policies.

1.ABSTRACTWith its ability to emulate microarchitectures and functional characteristics of native organs in vitro, induced pluripotent stem cell (iPSC) technology has enabled the generation of a plethora of organotypic constructs, including that of the human midbrain. However, reproducibly engineering and differentiating such human midbrain organoids (hMOs) under a biomimetic environment favorable for brain development still remains challenging. This study sets out to address this problem by combining the potential of iPSC technology with the advantages of microfluidics, namely its precise control over fluid flow combined with sensor integration. Here, we present a novel sensor-integrated platform for the long-term cultivation and non-invasive monitoring of hMOs under an interstitial flow regime. Our results show that dynamic cultivation of iPSC-derived hMOs maintains high cellular viabilities and dopaminergic neuron differentiation over prolonged cultivation periods of up to 50 days.

AbstractThe digital lifecycle encompasses definitive processes for data curation and management, long-term preservation, and dissemination, all of which are key building blocks in the development of a digital library. Maintaining a complete digital lifecycle workflow is vital to the preservation of digital cultural heritage and digital scholarship. This paper considers digital lifecycle programs for digital libraries, noting similarities between the digital and print lifecycles and referring to the example of the Digital Dunhuang project. Only through a systematic and sustainable digital lifecycle program can platforms for cross-disciplinary research and repositories for large aggregations of digital content be built. Moreover, advancing digital lifecycle development will ensure that knowledge and scholarship created in the digital age will have the same chances for survival that print-and-paper scholarship has had for centuries. It will also ensure that digital library users will have effective access to aggregated content across different domains and platforms.

Technological developments have changed the concepts of publication, reproduction and distribution. However, legislation, and in particular the Legal Deposit Law has not adjusted to these changes – it is very restrictive in the sense of protecting the rights of authors of electronic publications. National libraries and national archival institutions, being aware of their important role in preserving the written and spoken cultural heritage, try to find different legal ways to live up to these responsibilities. This paper presents some legal aspects of archiving Web pages, examines the harvesting of Web pages, provision of public access to pages, and their long‐term preservation.

Long Term Preservation

Digital preservation systems and practices are rooted in research and development efforts from the late 1990s and early 2000s when the cultural heritage sector started to tackle these challenges in isolation. Since then, the commercial sector has sought to solve similar challenges, using different technical strategies such as software defined storage and function-as-a-service. While commercial sector solutions are not necessarily created with long-term preservation in mind, they are well aligned with the digital preservation use case. The cultural heritage sector can benefit from adapting these modern approaches to increase sustainability and leverage technological advancements widely in use across Fortune 500 companies.
