Where to Start: Creating a Roadmap for Collection Storage Planning Through a Collaborative Values-Based Approach: A National Endowment for the Humanities Sustaining Cultural Heritage Collections project at The New York Public Library

Collection storage is one of the most complex collaborations a museum, library, or archive can undertake. A high-level initial assessment can help overcome the inertia and complexity that overwhelms larger organizations due to the number of stakeholders, spaces, and collections. Large institutions need to rise above room-level preservation issues and focus on global, values-based thinking. With support from the Sustaining Cultural Heritage Collections (SCHC) program of the National Endowment for the Humanities (NEH), The Research Libraries of the New York Public Library (NYPL) designed a collaborative pre-planning exercise to inform long-range collection storage planning for over fifty storage areas within its Manhattan research centers. Pulling together experts in architecture, preservation environment, and sustainability to review NYPL’s storage needs in collaboration with an internal team of stakeholders, the project established foundations for ongoing values-based collaborative planning. Project design and considerations on synthesizing observations into recommendations are discussed in this article.

Challenges and prospects for teaching ocean literacy in Brazilian schools

This study took as a case study the perspective of teachers working in the State of Rio de Janeiro by 53 interviews to investigate the challenges and prospects of including content about the ocean in Brazilian school classrooms. The data were subjected to content analysis and explored quantitatively using Descending Hierarchical Classification (DHC) and Factor Correspondence Analysis (FCA) of word and terms used by teachers in their discourse. The main difficulties reported in including themes related to the ocean and marine environments in classes were the absence of OL in the school curriculum and university education, as well as the limited time to work on these subjects in classes, which is in line with the challenges faced by teachers from other countries. On the other hand, Brazilian teachers cited particular problems of Brazilian formal education, such as the need for professional development, support for an education with an interdisciplinary emphasis, and provision of financial resources for schools. However, DHC analysis also indicates strong connection of the teachers with the ocean due to sea fascination (24% of the answers in the textual corpus), spiritual and emotional connection (26.7%), leisure (22.7%) and professional interest (26.7%). Furthermore, the textual corpus also identified that teachers recognize the importance of teaching marine topics due to: students live in coastal areas (32.2%), the provision of ecosystem services (19.9%), preservation issues (34.2%), and limited student knowledge on these themes (13.7%). These data can help formulate educational policies to mitigate OL teaching barriers in Brazilian schools.

Special structural Gramian approximation methods for model order reduction of time‐delay systems

AbstractModel order reduction methods via low‐rank approximation of Gramians for time‐delay systems are developed in this paper. The main contribution is to achieve the balancing and truncation of the system by utilizing low‐rank decomposition of the Gramians combined with the low‐rank square root framework. Here, based on Laguerre expansion technique, the low‐rank factorization of the system Gramians is realized via a linear system with special structure, thus enabling an efficient implementation of the reduction process. Furthermore, the issue of stability preservation is briefly described. We employ the dominant subspaces projection model reduction method to mitigate the effects which may accidentally produce unstable reduced models. Finally, numerical results verify the performance of the approximation‐Gramian methods.

Some features of natural spawning and problems of artificial reproduction of the cherry salmon Oncorhynchus masou (Brevoort, 1856)

The article discusses certain aspects of the dispersal and biology of cherry salmon, Oncorhynchus masou (Brevoort, 1856). It is noted that the species is the southernmost within the Pacific Salmon family and is also the only member of the Oncorhynchus genus whose habitat is exclusively in Asia. The decline in the number of cherry salmon across their range has been highlighted, and the main underlying factors have been identified. Some features of cherry salmon spawning run in various parts of their range are examined. A long stay of spawners in fresh water before spawning with preservation of feeding behavior is noted, which makes the species an extremely compelling object of recreational and commercial fishing. Some features of natural reproduction, such as spawning timing and fertility, depending on the habitat and size of the spawners, are indicated. The issue of preserving and restoring the species population is touched upon; the most appropriate method of its implementation is the artificial reproduction of the young with subsequent release into the natural habitat. The paper highlights a number of obstacles to the implementation of such programs, such as the undeveloped technology for growing young masu salmon and the difficulty of optimizing the temperature regime at hatcheries. As one of the limitations to increasing release volumes, it is indicated that masu salmon belongs to a species that have a long freshwater period, with the young spending up to three years in the river. A large number of juvenile masu salmon in the river leads to insufficient food supply and high mortality. In order to overcome this factor, it has been proposed to conduct research aimed at stimulating the smoltification of hatchery salmon fingerlings. This measure will allow significantly increasing the number of smolt and the return rates of spawners, which can be removed without affecting the natural populations.

DNA profiling in India: Addressing issues of sample preservation, databasing, marker selection, & statistical approaches

DNA technology is the gold standard with respect to the identification of individuals from biological evidence. The technology offers the convenience of a universally similar approach and methodology for analysis across the globe. However, the technology has not realised its full potential in India due to the lack of a DNA database and lacunae in sample collection and preservation from the scene of crime and victims (especially those of sexual assault). Further, statistical interpretation of DNA results is non-existent in the majority of cases. Though the latest technologies and developments in the field of DNA analysis are being adopted and implemented,very little has been enacted practically to improve optimise sample collection and preservation. This article discusses current casework scenarios that highlight the pitfalls and ambiguous areas in the field of DNA analysis, especially with respect DNA databases, sampling, andstatistical approaches to genetic data analysis. Possible solutions and mitigation measures are suggested.

Enhancing security and privacy in smart agriculture: A novel homomorphic signcryption system

Technology driven Smart Agriculture is transforming modern day farming practices through digital tools and real-time data analysis. It monitors plant health in both soil and soilless cultivation, promoting environmentally responsible practices by utilizing integrated sensors and precision methods. Despite the significant potential benefits, challenges persist in ensuring data security in the smart agriculture frameworks. The existing research has explored various mechanisms to cater these issues, yet these solutions susceptible to known attacks i.e., Confidentiality, Authentication, Privacy preservation. Notably, the available schemes in open literature face performance deficiencies due to an overreliance on Rivest-Shamir-Adleman (RSA), bilinear pairing, and elliptic curve (EC). To comprehensively address these challenges, this study presents a novel approach via employing homomorphic Signcryption based on Hyper-Elliptic Curves (HEC). Our HEC based Signcryption technique enhances security with lower computational cost and communication overhead as compared to the existing techniques. Furthermore, our solution provides the best performance in terms of efficiency, addressing the privacy preservation issues with conformance to the (Confidentiality, Integrity, and Availability) CIA triad. For proof of concept and correctness, we have validated the results in Scyther tool, with the assurance that proposed scheme is correct, verified, and resistant against known set of attacks. The proposed scheme achieves a remarkable reduction in both computational and communication costs around 95.08 % and 89.28 % respectively, enhancing practicality and suitability for real-world implementation. Thus, making it a suitable candidate for employing in smart agriculture environments, encompassing both soil and soilless cultivation scenarios. This research contributes a robust, secure, cost effective, and efficient solution to the challenges posed by the evolving landscape of agriculture, paving the way for enhanced data protection and system resilience in smart agriculture systems.

Standardizing Collections Record Data for Increased Understanding of Glass Collections Across the Smithsonian Institution

ABSTRACT The information contained in museum collections catalog databases is an invaluable resource for understanding and caring for collection items. The identification and grouping of items in a collection based on criteria such as location of manufacture, use, or materials composition allows for items at greater risk for long term preservation issues to be more appropriately monitored and cared for. However, identifying these items can be difficult, particularly when the collections data or terminology included in collections catalogs and databases vary significantly between items or across collections. This paper discusses the process and results of a data consolidation and cleaning campaign that was undertaken by the Smithsonian’s Glass Deterioration Working Group. This work was done in order to develop a consistent database of glass and glass-containing collection items that is able to be effectively queried for items of particular concern or interest from a preservation standpoint.

Historic Preservation in Legacy City Comprehensive Plans

This paper focuses on the ways in which recent comprehensive planning efforts in legacy cities address issues of historic preservation. Using 15 comprehensive plans as archival sources, we conduct textual analysis to explore how each of the plans incorporates historic preservation. The findings confirm existing research that suggests historic preservation has grown into an integral component of city planning efforts. The research offers insights into the current relationship between preservation and city planning, particularly within the context of legacy cities, and suggests that, despite recent practice, preservation remains a more palatable strategy than widespread demolition.

Identifying autism spectrum disorder from multi-modal data with privacy-preserving

The application of deep learning models to precision medical diagnosis often requires the aggregation of large amounts of medical data to effectively train high-quality models. However, data privacy protection mechanisms make it difficult to perform medical data collection from different medical institutions. In autism spectrum disorder (ASD) diagnosis, automatic diagnosis using multimodal information from heterogeneous data has not yet achieved satisfactory performance. To address the privacy preservation issue as well as to improve ASD diagnosis, we propose a deep learning framework using multimodal feature fusion and hypergraph neural networks for disease prediction in federated learning (FedHNN). By introducing the federated learning strategy, each local model is trained and computed independently in a distributed manner without data sharing, allowing rapid scaling of medical datasets to achieve robust and scalable deep learning predictive models. To further improve the performance with privacy preservation, we improve the hypergraph model for multimodal fusion to make it suitable for autism spectrum disorder (ASD) diagnosis tasks by capturing the complementarity and correlation between modalities through a hypergraph fusion strategy. The results demonstrate that our proposed federated learning-based prediction model is superior to all local models and outperforms other deep learning models. Overall, our proposed FedHNN has good results in the work of using multi-site data to improve the performance of ASD identification.

Preservation of Intangible Ethnocultural Heritage in the Electronic Environment

The article considers the issues of preserving and updating the ethnocultural heritage of the peoples of the Russian Federation within the framework of the activities of museums, houses of folk art, higher educational institutions, academic research institutes. Institutions for which the preservation of cultural heritage is not the main essential activity, but has recently been actively developing, are characterized. These are federal and national universities and research institutes of the Russian academy of sciences. Universities integrate successfully knowledge related to intangible cultural heritage into educational programs. Research institutes have become reference bases in their regions in the study and preservation of national languages as objects of intangible cultural heritage, national literature and ethnography. The prospects for such activities of libraries are considered, a new role of which is given in the Federal Law N 402-FL “On the intangible ethnocultural property of the Russian Federation”. The possibility of digitizing and forming digital collections of objects of intangible cultural heritage recorded in the form of texts and static images in libraries, as well as information objects existing in the form of temporary representation (recording of musical works, dances, folklore) has been identified. Particular attention in digitization in libraries should be paid to funds on national languages, collections of audio recordings of folk music and ethnographic collections. Examples of the practice of presenting intangible ethnocultural heritage on federal and regional portals/sites are given.

Sustainable adsorbent frameworks based on bio-resourced materials and biodegradable polymers in selective phosphate removal for waste-water remediation.

Phosphorus to an optimum extent is an essential nutrient for all living organisms and its scarcity may cause food security, and environmental preservation issues vis-à-vis agroeconomic hurdles. Undesirably excess phosphorus intensifies the eutrophication problem in non-marine water bodies and disrupts the natural nutrient balance of the ecosystem. To overcome such dichotomy, biodegradable polymer-based adsorbents have emerged as a cost-effective and implementable approach in striking a "desired optimum-undesired excess" balance pertaining to phosphate in a sustainable manner. So far, the reports on adopting such adsorbent-approach for wastewater remediation remained largely scattered, unstructured, and poorly correlated. In this background, the contextual review comprehensively discusses the current state-of-the-art in utilizing biodegradable polymeric frameworks as an adsorbent system for phosphate removal and its efficient recovery from the aquatic ecosystem, while highlighting their characteristics-specific functional efficiency vis-à-vis easiness of synthetic and commercial viability. The overview further delves into the sources and environmental ramifications of excessive phosphorus in water bodies and associated mechanistic pathways of phosphorus removal via adsorption, precipitation, and membrane filtration enabled by biodegradable (natural and synthetic) polymeric substrates. Finally, functionality optimization, degradability tuning, and adsorption selectivity of biodegradable polymers are highlighted, while aiming to strike a balance in "removal-recovery-reuse" dynamics of phosphate. Thus, the current review not only paves the way for future exploration of biodegradable polymers in sustainable cost-effective adsorbents for phosphorus removal but also can serve as a guide for researchers dealing with this critical issue.

A Study of the Kharkiv Architectural Avant-Garde

The article addresses the issue of preserving Kharkiv’s architectural heritage from the first third of the 20th century. The main focus is on the preservation of authenticity of the early modernist heritage in the context of a crisis situation associated with the overall state of heritage preservation in Ukraine and during active military operations. The research was conducted in the context of the planning development and spatial structure of the Kharkiv historical center and suburbs, where new workers’ settlements were formed, as well as considering the architectural layers within the structure of historical districts of Kharkiv. The main objective of the study is to determine the value and authenticity of the architectural heritage of early modernism. The study employed the methods of historical, retrospective, and comprehensive analysis. The general plan of the “Socialist Reconstruction of Kharkiv” from 1931-1933 and the historical-architectural reference plan of Kharkiv from 2019 were analysed as additional sources. The research results provide comprehensive information about the architectural and urban heritage of this period and emphasize the attention to the issue of preservation of authenticity. The conclusions of this work will serve as a basis for further development of specific measures for the conservation, restoration, and preservation of historical monuments in Kharkiv from the first third of the 20th century. The research will also contribute to raising public awareness about the value of early modernist architectural heritage and encourage the implementation of restoration programs to preserve these important landmarks.

A 121‐ka record of Western Andean fluvial response to suborbital climate cycles recorded by rhythmic grain size variations of the Lima fluvial fan

AbstractA complete, fluvial stratigraphic record for the last glacial period of the Western Andes in Peru is not available due to preservation issues and spatial variability in sedimentation. Deposits are typically restricted to incomplete records of fluvial terraces or localised occurrences of alluvial fans and landslides. These landforms are thought to have formed under a regime of climate cyclicity controlling increases in precipitation. Because of the fragmented preservation of these deposits, as well as dating uncertainties, it remains unclear if orbital climate cycles, such as the precession cycle, or suborbital cycles, such as the wet Heinrich events, are driving Andean sedimentation. In this paper, we try to answer this question through a sedimentological–stratigraphical analysis of a much more complete sedimentary sequence than usually found in the region. We present the results of a grain size analysis of 5000 clasts and 13 new luminescence ages of a 52‐m‐long, stratigraphic section of the Lima fluvial fan in Peru. Bayesian age–depth modelling resulted in a robust chronostratigraphic framework and derived sedimentation rates. The stratigraphic record registered sedimentation from 121.7 ± 4 to ka. Three major sedimentation periods occurred between 121.7 to , 87 ± 1 to , and to ka. These periods registered various unconformities and coarsening–fining upward sequences which chronologically correlate to suborbital pluvial periods, recognised from speleothems and lake records, that drove fluvial deposition. They also correlate with the timing of other recognised sedimentation events throughout the Western Andes. Marine regression resulted in fan progradation and not in incision. The Lima fan stratigraphy represents therefore the most complete, last glacial fluvial record for the Peruvian Western Andes to date and it highlights the potential of fluvial fans as recorders of suborbital climate variability.

Current Status and Issues of Collaboration Between Physicians and Pharmacists in Fertility Preservation.

Purpose: This study addresses the critical issue of fertility preservation among young patients with cancer in Japan, recognizing the brief decision-making window and the need for comprehensive support. Pharmacists, well-versed in the side effects of anticancer drugs, can play a vital role in this support process. However, the extent of pharmacists' involvement in fertility preservation remains unclear. We aimed to investigate pharmacists' roles in addressing cancer treatment-induced fertility concerns and their collaboration with physicians, offering insights into enhancing pharmacist participation in fertility preservation. Methods: A survey conducted between April and July 2022 targeted doctors and pharmacists at cancer treatment hospitals, along with pharmacists affiliated with the Japanese Society of Pharmaceutical Health Care and Sciences. Results: Our findings indicated that although pharmacists had limited knowledge about gonadotoxicity and fertility, they expressed readiness to conduct research and provide information when consulted. Approximately 10%-20% of the pharmacists participated in explaining the primary disease at diagnosis. Pharmacists played a more prominent role after establishing chemotherapy regimens, with less involvement in its formulation. Notably, treatment decision case conferences emerged as crucial forums for gathering patient data, confirming treatment plans, and identifying those in need for fertility preservation information. Roughly half of the pharmacists attended these conferences, suggesting a need for increased participation. Conclusion: Enhancing physician-pharmacist collaboration could be pivotal for effective fertility preservation. This requires augmenting the knowledge and awareness of both professions and encouraging greater participation in case conferences to create a conducive environment for addressing this critical aspect of cancer care.

Retrospective study evaluating dental side effects of radiotherapy in patients treated for head and neck cancer

IntroductionHead and neck cancer squamous cell carcinoma (HNSCC) is the seventh most common cancer worldwide with around 600,000 new diagnosis each year. Nowadays, in locally advanced disease, radiotherapy (RT) play an important role, this with or without chemotherapy in organ preservation strategies. More specific for early stage localized disease, RT (or surgery) seems to give similar results on locoregional control (LRC) and choice is made according to the organ preservation issue. Despite the fact that technical improvements have been made to optimize the radiation dose delivery and minimize the normal tissue toxicity, RT is associated with potential early and late toxicities. Osteoradionecrosis of the jaw (ORNJ), especially seen after teeth extraction, is one of the associated toxicities and can significantly impair the patient's quality of life. Because of the fear of developing ORNJ, one is very reluctant to extract or place a dental implant post-radiotherapy, especially in high irradiation dose zones (>40 Gy). Hence, it is important to define teeth at risk of future extraction before initiating RT and to handle those in high-risk irradiation zones. In order to optimise extractions, we created a predictive model of the expected irradiation dose, and thus the need for extraction, to the teeth bearing bones. The aim of this study is to validate our model and to define the potential relationship between the radiation dose received by each tooth and the dental complications observed. Material and methodsBetween March 2012 and March 2018, patients with HNSCC treated by intensity modulated RT were retrospectively analysed. The mean irradiation dose for each tooth was generated on the administered treatment plan by contouring each tooth separately on each dosimetric scan section using dedicated software (Eclipse, Varian). In order to validate our predictive model, we compared the actual generated/administered teeth irradiation doses with the irradiation doses predicted by our model. ResultsOur predictive model was accurate in 69.6% of the cases. In 12.5% of cases the predicted dose was higher than the calculated dose and lower in 17,8% of the cases. A correct- or over-estimation (is the latter being clinically less worrying than an underestimated dose) was achieved in 82% of cases. For the 18% of cases underfitting, the mean margin of error was 5.7 Gy. No statistically significant association was found between the development of caries and doses to the teeth, doses to the parotid glands or dental hygiene. However, a significant association between dental irradiation at more than 40 Gy and the occurrence of dental fractures (p = 0.0002) were demonstrated. ConclusionsOur predictive model seems to be 82% accurate for dose prediction, hence might be helpful for optimizing/minimizing prophylactic extractions. Indeed, following our model, professionals could decide not to extract damaged teeth in areas not at risk of ORNJ, lowering morbidity during and after RT. Contrary to the literature, no relationship was found between the occurrence of dental caries and parotid irradiation and the patient's oral hygiene. However, for the first time, a highly significant correlation between the occurrence of dental fracture and dental irradiation at more than 40 Gy was observed.
