The collection of faunal remains considered in this study was obtained from excavations at Qara Tepe, Sagzabad, in 2013, 2014, and 2015, with a particular focus on the Iron Age II and III. A large part of the faunal assemblages was successfully identified. The collection is formed by a range of species, among them being small ruminants (Capra aegagrus, Ovis Aries, Gazella subgutturosa), large ruminants (Bos Taurus, Cervidae, Equidae (Equus caballus, Equus africanus asinus), Carnivora (Canis lupus familiaris, Sus scrofa), Rodentia, Muridae, Lagomorpha, Aves, and Camelidae (Camelus dromedarius). The total of 1200 identifiable pieces belongs to 16 discrete species. The most frequent category is small ruminants, i.e., goats and sheep, a fact indicating that a climate favorable for the breeding of these species characterized the region during the Iron II‒III. The observation also highlights the significant role these animals played in the local subsistence economy during the relevant period. Related remains are profusely associated with human skeletal remains and cemetery burials at Sagzabad. Some are pretty complete, lacking any indications of cutting or butchery. Potential reasons for the abundance of these species were their adaptation to the landscape and their ease of breeding.

The purpose of this research is to investigate the architectural index elements in local and Jame Mosques. “Mosque” is an allusion to a place of worship, which should be able to induce a sense of worship in its audience. The forms and roles in the building are the shapes that are influenced by the content and affect the human sensory perception and are directly related to people's beliefs and religion. Therefore, the main issue in its design is the suitability of the architecture of the mosques with their dignity and functional content. When Islam emerged, there was no idea of the principles of building a mosque and the only pattern was the Prophet's house. Iranian architectural styles have changed and evolved during different periods of history, in accordance with governments, religions and beliefs, and with the arrival of Islam, the Iranian architectural style underwent many changes. In general, several prominent elements are used in the architecture of the mosque: the courtyard, the porch, the shrine, the mihrab, the dome and the minaret. However, some mosques lack elements or some have several elements of the same element. So, in this research, by examining the historical (local and Jame) mosques of Zanjan, their architectural index elements which are unknown aspects of this research, as well as to determine the factors influencing the design of these mosques that take the ambiguous dimension of the research, it was revealed through library studies and the descriptive/analytical method of existing documents and research.

The preservation of invaluable cultural heritage assets, including ancient artifacts and historical sites, remains a critical global concern. Existing perimeter protection methods, such as CCTV systems, infrared sensors, and conventional surveillance technologies, often exhibit significant limitations in terms of spatial coverage, sensitivity to subtle intrusions, and adaptability to varying environmental conditions. This paper presents an innovative and highly effective solution utilizing fiber optic sensor (FOS) technology, which offers numerous advantages, including lightweight construction, immunity to electromagnetic interference, ease of installation, high sensitivity, and reliable performance across a broad range of applications. Specifically, the study introduces novel designs for distributed acoustic FOS systems based on Michelson, Mach-Zehnder, and Sagnac interferometric configurations. Through comprehensive theoretical analysis, simulation modeling, and experimental validation, the research explores their practical utility in protecting cultural heritage. Two detailed case studies—focused on the Louvre Museum in France and the ancient archaeological site of Persepolis in Iran—demonstrate the implementation, functionality, and real-world efficacy of the proposed systems. The findings highlight how these FOS networks, particularly when combined with advanced artificial intelligence and machine learning algorithms, can effectively detect, classify, and localize human-induced acoustic disturbances such as walking or digging, while minimizing false alarms caused by environmental noise. This enhanced discrimination capability not only improves overall security but also significantly reduces the need for extensive human surveillance. Moreover, these systems enable precise, continuous, and real-time 24-hour monitoring over vast indoor and outdoor areas. In conclusion, the integration of FOS technology offers a scalable, intelligent, and transformative approach to addressing the complex and evolving challenges associated with the long-term preservation and protection of cultural heritage sites around the world.

Timurid coins serve as a mirror reflecting the significant economic and political events of the era, and their study can provide deeper insights into the economic and social dynamics of the Timurid period. This research examines the Timurid coins housed in the Museum of Bu-Ali Sina Mausoleum using X-ray fluorescence spectroscopy. A specialized review of the initial results obtained from XRF spectroscopy, particularly in numismatic studies, holds significant importance and can be a fundamental step toward reducing errors and enhancing precision in interdisciplinary analyses. XRF technology, as a non-destructive method, enables precise examination of the chemical composition and identification of elements present in coins. However, without meticulous monitoring and comprehensive reevaluation of the obtained results, misinterpretations and uncertainty in historical analyses may arise. The research questions focus on the value of reinterpreting and analyzing XRF spectroscopy data and their role in identifying counterfeit coins and understanding economic and cultural characteristics in numismatic studies. The central hypothesis of the study posits that raw XRF spectroscopy data do not provide accurate results, and in-depth analysis by experts is required for a precise examination of coins. This research also highlights the importance of detailed spectrum analysis, technical challenges in data interpretation, and the use of interdisciplinary approaches to enhance the accuracy of results. The findings reveal that a more profound reinterpretation of XRF spectroscopy data significantly contributes to better understanding the chemical composition of coins and preserving cultural heritage treasures. It also provides deeper insights into the economic policies and activities of the Timurid period.
