MODELING OF THE AUTOMATED COMPLEX COMPONENTS FOR SEGREGATED RESIDUES GATHERING OF OPERATIONAL PRINTING

Abstract. An overview of the printing industry primary measures regarding the balanced implementation of the sustainable development goals at the regional level was carried out. Based on the latest works analysis in the direction of the enlargement of branch waste management systems, the solutions insufficiency for the limited financial situations of small businesses is revealed, and the relevance of finding optimal means of gathering segregated waste and their temporary storage at the enterprise is shown. The criteria have been established and the stratification of typical categories of orders the operational printing has been carried out according to print run and rest volume. The requirements for the collection and storage of waste raw materials and consumables have been clarified and expanded, in particular regarding the provision of microclimatic conditions. In order to model effective business processes of pro­duction residues management, the construction of a universal complex for target cumulative of pre-segregated substrate scraps in the form of a smart container with a weighing terminal is substantiated. For flexible allocation of corporate flows, the hardware part is implemented from measuring, supervisory and communication blocks depending on their purpose in the automated microprocessor platform. The researched printing waste types the built algorithm of the life cycle of their cumulating made it possible to draw up an architectural diagram of segregator system and determine the main components hierarchy of printing waste receptacle when order manufacturing. As a result, analytical models were built and the modeling of automated complex of segregated residues gathering in operational printing was carried out based on created microcontroller system for monitoring of mass and climate control of cumulated surpluses to maintenance proper conditions their subsequent recycling.

Comparison of urinary 3-hydroxybenzo(a)Pyrene (3-OHBaP) and trans-anti-7,8,9,10-tetrahydroxy-7,8,9,10-tetrahydrobenzo(a)Pyrene (TetraolBaP) as biomarkers of exposure to carcinogenic BaP

IntroductionBiomonitoring of exposure to carcinogenic Benzo(a)Pyrene is generally based on measurement of urinary 3-hydroxybenzo(a)pyrene (3-OHBaP), but its analysis is complex and only reflects the BaP detoxification pathway. TetraolBaP, another BaP metabolite resulting from the metabolic activation pathway, is now available but has not yet been studied in occupational settings or compared with 3-OHBaP. MethodsBiomonitoring was carried out on 118 subjects working in the aluminium smelting industry. 3 urine samples were collected from each subject at the beginning and end of the working week. Pyrene metabolite (1-hydroxypyrene) and the two BaP biomarkers (3-OHBaP and TetraolBaP) were analysed using LC-Fluorescence and GC-NCI-MS-MS. ResultsThe workers studied were found to be highly exposed, with 1-OHP and 3-OHBaP frequently exceeding maximum recommended values in occupational settings. Maximum concentrations were measured at end of shift+16h for all biomarkers, highlighting dermal exposure and/or temporary storage. Correlations were strong between 1-OHP and 3-OHBaP (r = 0.68–0.75) as well as between 3-OHBaP and TetraolBaP (r = 0.67–0.78), and moderate between 1-OHP and TetraolBaP (r = 0.59–0.76). While TetraolBaP levels were higher at low PAH exposures, TetraolBaP increased much more slowly at high exposures, indicating progressive saturation of the bioactivation pathway. The [3-OHBaP]/[TetraolBaP] ratio was found to be significantly lower in chronically exposed workers. Urinary TetraolBaP levels corresponding to 1-OHP (2.5 μg/L or 1 μmol/mol creatinine) or 3-OHBaP (0.4 nmol/mol creatinine) guidance values were found to range between 0.84 and 0.95 nmol/mol creatinine. ConclusionsTetraolBaP, resulting from carcinogenic BaP's metabolic activation pathway, was shown to be a diagnostically specific and sensitive biomarker for determining subjects' toxic internal exposure to PAHs in different contexts (occupational settings, environment) and assessing health risks.

Navigating the complex policy landscape for carbon farming in The Netherlands and the EU

Background The EU carbon removal and carbon farming (CRCF) framework sets the quality requirements for voluntary greenhouse gas certification schemes for i) permanent removal, ii) temporary carbon storage in long-lasting products, iii) temporary carbon storage from carbon farming, and iv) soil emission reduction. The next step is to develop “tailored certification methodologies for different types of carbon removal activities.” Via CRCF compliant certification schemes, certificates can be issued and sold to generate extra funding for carbon farming via voluntary carbon markets or other (future) performance-based incentive schemes (e.g., Agri sector Emissions Trading Scheme). Method We provide a qualitative assessment of the complex landscape of carbon farming incentive schemes and their associated monitoring, reporting, verification, and certification (MRV-C) frameworks. To illustrate these complexities, we take the farmers’ perspective of a Dutch dairy farmer that wants to implement different carbon farming activities (i.e., a portfolio), while aiming to secure a decent farm-level income. We discuss the farmers’ challenge by analyzing different options and routes for the financial valorization for several carbon farming activities. Results We find that the incremental MRV-C and incentive schemes, like the EU CRCF and potential agri-ETS are likely to add to the existing administrative burden for (carbon) farmers in the EU. Proper alignment, integration and standardization of the EU CRCF with existing MRV-C infrastructure(s) is needed to limit the administrative burden and transaction costs. Also, there is a need to provide better ex-ante clarity to (carbon) farmers and investors on the complementarity of incentive schemes from different policy domains (e.g., agriculture, climate, energy, bioeconomy). Conclusion We argue that the complexity of the MRV-C and incentives landscape ads to the administrative burden and flag this a potential source of inertia for investments in carbon farming. We conclude with recommendations to simplify and streamline the policy mix and MRV-C processes.

Traffic Intensity as a Factor Influencing Microplastic and Tire Wear Particle Pollution in Snow Accumulated on Urban Roads

Traffic-related roads are an underestimated source of synthetic particles in the environment. This study investigated the impact of traffic volume on microplastic (MP) and tire wear particle (TWP) pollution in road snow. An examination was conducted in a medium-sized city situated in northeastern Poland, known for being one of the cleanest regions in the country. MPs and TWPs were found at all 54 sites, regardless of the intensity of traffic. The average concentration for all samples was 354.72 pcs/L. Statistically significant differences were found between the average values of the particle concentration on low, medium, and heavy traffic roads, amounting to 62.32 pcs/L, 335.97 pcs/L, and 792.76 pcs/L, respectively. Within all three studied groups of roads, MPs and TWPs with the smallest size, ranging from 50 to 200 μm, were prevalent. In all of the studied groups of roads, four analyzed shapes of particles were found, with irregular fragments being the most abundant form (89.23%). The most frequently recorded color among the collected samples was black (99.85%), and the least frequently recorded color was blue, constituting only 0.01%. This study suggests that snow cover on the roads may act like a temporary storage of pollutants during winter particularly in the temperate climate zone and, after thawing can significantly increase the concentration of MPs and TWPs in surface waters. Possible measures to decrease the release of MPs and TWPs into the environment in the city may include reducing the traffic volume and speed, implementing street sweeping, utilizing filtration chambers, and installing stormwater bioretention systems or settling ponds.

High‐performance polybenzimidazole blend membranes based on a commercially available anion‐exchange polymer and F6PBI for vanadium redox flow batteries

AbstractRenewable energy is essential for the transition to a carbon‐neutral society. Due to their intermittent nature, temporary storage is required. The all‐vanadium redox flow battery (VRFB) is a promising technology for this purpose. Commercially available membranes, such as the FAPQ330 from Fumatech BWT, already show reasonable performance but still have room for improvement in selectivity and conductivity. In this study, we developed new ductile porous blend membranes based on the polybenzimidazole F6PBI by mixing it with poly(diallyldimethylammonium bis(trifluoromethane)sulfonimide), which was prepared from the commercially available poly(dimethylammonium chloride) (PDADMAC). Three types of membranes with different amounts of PDADMA*TFSI in the blend solution were prepared and characterized. Ex‐situ conductivity measurements showed conductivities between 8.3 and 30.5 mS cm−1. Ex‐situ permeability tests revealed significantly lower permeabilities compared to the reference membrane FAPQ330. No change in ex‐situ conductivity was measured after the ex‐situ stability test. F6PBI‐PDAD37 reached the highest energy efficiency at 50, 100, and 200 mA cm−2 among all tested membranes. For example, a VRFB single‐cell equipped with F6PBI‐PDAD37 showed an improved EE of 76.5% at 200 mA cm−2, which is higher than the EE of FAPQ330 (74.3%).

Compilation of Shape Operators on Sparse Arrays

We show how to build a compiler for a sparse array language that supports shape operators such as reshaping or concatenating arrays, in addition to compute operators. Existing sparse array programming systems implement generic shape operators for only some sparse data structures, reduce shape operators on other data structures to those, and do not support fusion. Our system compiles sparse array expressions to code that efficiently iterates over reshaped views of irregular sparse data structures, without needing to materialize temporary storage for intermediates. Our evaluation shows that our approach generates sparse array code competitive with popular sparse array libraries: our generated shape operators achieve geometric mean speed-ups of 1.66×–15.3× when compared to hand-written kernels in scipy.sparse and 1.67×–651× when compared to generic implementations in pydata/sparse. For operators that require data structure conversions in these libraries, our generated code achieves geometric mean speed-ups of 7.29×–13.0× when compared to scipy.sparse and 21.3×–511× when compared to pydata/sparse. Finally, our evaluation demonstrates that fusing shape and compute operators improves the performance of several expressions by geometric mean speed-ups of 1.22×–2.23×.

It's about (taking up) space: Discreteness of individuals and the strength of spatial coexistence mechanisms.

One strand of modern coexistence theory (MCT) partitions invader growth rates (IGR) to quantify how different mechanisms contribute to species coexistence, highlighting fluctuation-dependent mechanisms. A general conclusion from the classical analytic MCT theory is that coexistence mechanisms relying on temporal variation (such as the temporal storage effect) are generally less effective at promoting coexistence than mechanisms relying on spatial or spatiotemporal variation (primarily growth-density covariance). However, the analytic theory assumes continuous population density, and IGRs are calculated for infinitesimally rare invaders that have infinite time to find their preferred habitat and regrow, without ever experiencing intraspecific competition. Here we ask if the disparity between spatial and temporal mechanisms persists when individuals are, instead, discrete and occupy finite amounts of space. We present a simulation-based approach to quantifying IGRs in this situation, building on our previous approach for spatially non-varying habitats. As expected, we found that spatial mechanisms are weakened; unexpectedly, the contribution to IGR from growth-density covariance could even become negative, opposing coexistence. We also found shifts in which demographic parameters had the largest effect on the strength of spatial coexistence mechanisms. Our substantive conclusions are statements about one model, across parameter ranges that we subjectively considered realistic. Using the methods developed here, effects of individual discreteness should be explored theoretically across a broader range of conditions, and in models parameterized from empirical data on real communities.

Cultural Therapy and Concern for the Archive. The Case of Documentary Video Archives by Tomáš Rafa

In this paper, the author explores current perspectives on contemporary art projects through the concept of the archive. By applying a theoretical framework termed “concern for the archive”, the author aims to elucidate complex relationships between the archive as a medium and the situated practices of contemporary art. The paper examines contemporary art as a form of temporary memory storage, particularly through the analysis of Tomáš Rafa’s documentary films. It addresses two key questions: What specific aspects of concern for the archive can be identified in political or activist contemporary art? How does concern for the archive differ from archival care, and why is this distinction important? In the first section, the author discusses the “zones of contact” in political activist art, highlighting the formation of dialogical structures and distinguishing them from scientific research and purely documentary creation. The second section traces the layers of artistic training in Grzegorz Kowalski's renowned studio at the Academy of Fine Arts in Warsaw, where the author gained experience in organizing and documenting collective workshops. This part reveals the specifics of documentary video creation with its activist and archival overlaps. In the final sections, the author outlines a theoretical framework for interpreting documentary video pieces in relation to the concepts of archive, cultural trauma, and cultural therapy.

Improving working memory by electrical stimulation and cross-frequency coupling

Working memory (WM) is essential for the temporary storage and processing of information required for complex cognitive tasks and relies on neuronal theta and gamma oscillations. Given the limited capacity of WM, researchers have investigated various methods to improve it, including transcranial alternating current stimulation (tACS), which modulates brain activity at specific frequencies. One particularly promising approach is theta-gamma peak-coupled-tACS (TGCp-tACS), which simulates the natural interaction between theta and gamma oscillations that occurs during cognitive control in the brain. The aim of this study was to improve WM in healthy young adults with TGCp-tACS, focusing on both behavioral and neurophysiological outcomes. Thirty-one participants completed five WM tasks under both sham and verum stimulation conditions. Electroencephalography (EEG) recordings before and after stimulation showed that TGCp-tACS increased power spectral density (PSD) in the high-gamma region at the stimulation site, while PSD decreased in the theta and delta regions throughout the cortex. From a behavioral perspective, although no significant changes were observed in most tasks, there was a significant improvement in accuracy in the 14-item Sternberg task, indicating an improvement in phonological WM. In conclusion, TGCp-tACS has the potential to promote and improve the phonological component of WM. To fully realize the cognitive benefits, further research is needed to refine the stimulation parameters and account for individual differences, such as baseline cognitive status and hormonal factors.

An Analysis Management by Mike 21 Modelling at Rolak 70 Retention Pool in Jombang Regency, East Java Province, Indonesia

Some areas in Indonesia have high level of sedimentation problems that able to cause flooding, and one apparent solution is to build a retention pool. Sedimentation is deposition of material into the reservoir or dam due to environmental damage or erosion occurs in the river basin area. Sedimentation becomes the main factor in constructing the Rolak 70 Retention Pool, as an important component in controlling floods on the Konto River when the water discharge exceeds the maximum limit. From geography perspective, the modelling location is in waters located between 112° 11′ 22.85″ South Latitude and 7° 38′ 42.23″ East Longitude. The model area has northern boundary at the tip of Rolak 70 pool, while western boundary at the outlet of Rolak 70 pool. The lowest water depth value is located in upstream area of Konto River at coordinates of 112°11’27.81″ South Latitude and 7°38’49.27″ East longitude. Weight of soil sample taken from the research site was ± 1000 grams at each point, and the result of sediment sample test performed at the Soil Mechanics Laboratory of Civil Engineering Department, Sultan Agung University, Semarang showed that the research area is dominated by sand, followed by mud and gravel. There were several tests conducted include grain size analysis, hydrometer analysis, and specific gravity analysis to determine the D50 of the sediment. In the study area, several sampling points were taken, started from upstream area of the river in front of Rolak 70 building to the Rolak 70 Retention Pool. For this purpose, a MIKE 21 software modelling was used to determine distribution and lines of sedimentation in the study area. As visible from changes found in bed level morphology that occurred in Rolak 70 Retention Pool by cross section extraction, it can be seen that the largest change occurred in analysis for line 1 and the smallest bed level changes occurred in the analysis for line 6. Then, the result revealed that sedimentation tends to occur at large locations in upstream area of Rolak 70 Retention Pool, while the smallest sedimentation potential will happen at the downstream area of Rolak 70 Retention Pool. These results can be caused by changes of speed from the river flow which tends to decrease towards the end of Rolak 70 Retention Pool. So, the river flow has no more energy to carry heavy amount of sediments originating from the upstream area of the Konto River. By the existence of this retention pool, the need for rice field irrigation will not be disturbed by sediment deposits. In addition, the Rolak 70 Retention Pool can be used as temporary storage for material from Mount Kelud eruption where these materials can be utilized as building material or other useful purposes.

JUSTIFICATION OF THE FEASIBILITY OF COOPERATION BETWEEN FREIGHT FORWARDING ENTERPRISES AND CUSTOMS-LOGISTICS INFRASTRUCTURE OBJECTS

The purpose of the paper is to plan the activities of freight forwarding enterprises when organizing cooperation with customs-logistics infrastructure objects to meet customer needs. The efficiency indicators of cargo customs complexes, customs warehouses, and temporary storage warehouses were analyzed. The process of selecting customs-logistics infrastructure objects with varying levels of organizational, technical, and technological support was investigated. The proposed development will enable specialists of freight forwarding enterprises to form recommendations for cooperation with customs-logistics infrastructure objects in accordance with individual customer needs. Methodology. The determination of technical and operational performance indicators of customs-logistics infrastructure objects was implemented based on a simulation model developed in the GPSS software environment. This approach allows for the identification of deviations of generalized performance indicators of infrastructure objects from benchmark levels, which are formed taking into account customer requirements. Findings. To ensure a high level of competitiveness of the freight forwarding enterprise, it is necessary to use modern software systems capable of implementing management decisions regarding the formation of partnerships with customs-logistics infrastructure objects. Based on the assessment of technical and operational performance indicators of cargo customs complexes, customs warehouses, and temporary storage warehouses, and considering the main requirements of service customers, it becomes possible to select the most efficient business entity for cooperation. A significant advantage of the proposed development is the ability to perform a comparative analysis of the efficiency indicators of all studied enterprises in relation to the benchmark infrastructure object. Originality. The proposed simulation model for selecting customs-logistics infrastructure objects will allow specialists of freight forwarding enterprises to make a choice of intermediary organizations based on a comparative analysis of the technical and operational performance of the studied objects. Practical value. The practical significance of this work lies in the fact that the proposed model enables the selection of the customs-logistics infrastructure object that most effectively meets the individual needs of the customer. This will make it possible to plan the work of the freight forwarding enterprise based on the implementation of organizational and management measures that will positively impact the internal processes of the organization and contribute to forming its competitive advantages in the market of freight forwarding services. This implementation will reduce the duration of freight forwarding and customs-logistics services and minimize commercial risks at all stages of foreign trade operations by establishing cooperation with the most efficient intermediary organizations.

Effect of temporary storage of cryopreserved cellular therapy products at −80⁰ celsius on cell recovery and viability

Cellular therapy (CT) involving the transplantation of hematopoietic progenitor cells (HPC) is a treatment modality for both benign and malignant disorders. All autologous products require cryopreservation while allogeneic product cryopreservation became more common during the Coronavirus disease 2019 pandemic. Cells are stored in liquid nitrogen (LN2) freezers which can malfunction and products may have to be temporarily stored in a mechanical −80 °C freezer if additional LN2 freezer space is not available. The practice of temporary short-term −80 °C storage is present but there is no study to show that the product is unaffected by the temporary storage at a significantly warmer temperature. In this study, we identified previously collected CT products that were cryopreserved for now-deceased recipients that had remaining cryovials with aliquots of products for quality control purposes. Vials from 20 collections were split into 4 groups of 5 in with one vial placed in temporary storage at −80 °C for 2–5 weeks before returning to LN2 storage while another vial remained in LN2 storage for the entire duration of the study. The vials were then simultaneously thawed, processed, and evaluated for total nucleated cell (TNC) and CD34 + cell count and TNC and CD34 + cell viability to determine if there were any differences induced by temporary −80 °C storage. No statistically significant differences were seen after 4 weeks of −80 °C storage; however, after 5 weeks, a statistically significant decrease in TNC viability and viable TNC count, but not CD34 + cell viability and viable CD34 + cell count was observed. These results provide some reassurance to CT processing labs that if there is a failure in their LN2 storage for cryopreserved products, these products may be safely stored at −80 °C for up to 4 weeks and returned to LN2 storage without compromising CD34 + cell viability.

Сharacteristics of demolition waste management in the regions of Ukraine

The volume of waste left from war-related destruction amounts to 10-12 million tons per year. Such volume is comparable to the annual volume of municipal solid waste generated in Ukraine. This situation led to formation of unauthorized landfills and complicated the existing problem of industrial, consumer, construction and demolition waste management. Consequently, the issue of destruction waste management became a pressing environmental and socio-economic problem. The objective of this research is to assess the characteristics of destruction waste management in the regions of Ukraine. Destruction waste is generated during construction of new buildings and public structures, as well as during renovation or demolition of existing buildings and structures; including general-use facilities. It is estimated that, before the war, nearly 7 million tons of construction and demolition waste was generated annually, with more than 50% being transported to municipal solid waste landfills. Specialized landfills for its disposal were virtually non-existent in the regions of Ukraine, so this waste, despite its resource value, was taken to municipal solid waste landfills or unauthorized dumps. Some components of construction and demolition waste are toxic. Destruction waste includes parts (fragments) of damaged (destroyed) objects, as well as materials and items that were inside or next to such objects at the time of damage (destruction) and/or during disassembly activities, including those that fully or partially lost their consumer properties and cannot be reused at the place of their origin or discovery. Destruction waste pollutes the environment, so one of the ways to reduce environmental risks is to develop an effective waste management system to stop chaotic processes during disassembly activities. Destruction waste differs from construction and demolition waste by the presence of accompanying hazardous components, complicating the development of a waste management system. The main components of destruction waste should be used as secondary raw materials for construction, production of building materials and other purposes. Provided that appropriate physical-geographic, engineering-geological, hydrogeological, technical, and socio-economic conditions are available, it is advisable to create temporary waste storage sites, with their subsequent use as secondary raw materials in the post-war period for restoration of civil, industrial, and transport infrastructure in the regions of Ukraine.

Asynchronous Memory Access Unit: Exploiting Massive Parallelism for Far Memory Access

The growing memory demands of modern applications have driven the adoption of far memory technologies in data centers to provide cost-effective, high-capacity memory solutions. However, far memory presents new performance challenges because its access latencies are significantly longer and more variable than local DRAM. For applications to achieve acceptable performance on far memory, a high degree of memory-level parallelism (MLP) is needed to tolerate the long access latency. While modern out-of-order processors are capable of exploiting a certain degree of MLP, they are constrained by resource limitations and hardware complexity. The key obstacle is the synchronous memory access semantics of traditional load/store instructions, which occupy critical hardware resources for a long time. The longer far memory latencies exacerbate this limitation. This article proposes a set of Asynchronous Memory Access Instructions (AMI) and its supporting function unit, Asynchronous Memory Access Unit (AMU), inside contemporary Out-of-Order Core. AMI separates memory request issuing from response handling to reduce resource occupation. Additionally, AMU architecture supports up to several hundreds of asynchronous memory requests through re-purposing a portion of L2 Cache as scratchpad memory (SPM) to provide sufficient temporal storage. Together with a coroutine-based programming framework, this scheme can achieve significantly higher MLP for hiding far memory latencies. Evaluation with a cycle-accurate simulation shows AMI achieves 2.42× speedup on average for memory-bound benchmarks with 1μs additional far memory latency. Over 130 outstanding requests are supported with 26.86× speedup for GUPS (random access) with 5 μs latency. These demonstrate how the techniques tackle far memory performance impacts through explicit MLP expression and latency adaptation.

435 Use of plant bioactives to improve the efficiency of rumen function

Abstract Plant bioactives, also known as phytogenics or phytobiotics, are secondary metabolites of plant origin that are deployed as host-defense mechanisms against predators or to enable them to be more competitive in their environment. These metabolites also regulate growth and reproductive functions in the plant. They can be grouped into three major classes: terpenoids, phenolic compounds, and alkaloids. Various studies have shown their worth in improving livestock production and health via insectifugal, organoleptic and enhanced rumen functions. Ruminants are critical to food security because they are able to convert poor-quality feed materials into nutritious products like meat. The rumen provides temporary storage of feed but serves the main function of digesting those complex materials through symbiotic relationships among prokaryotic and eukaryotic organisms within the rumen vat. Antimicrobial resistance and other health or social license challenges have led researchers to find acceptable replacements that will not exacerbate the health and social issues in animals and humans. Plant bioactives appeal to producers because of the ‘natural’ brand and because they are usually certified as generally recognized as safe (GRAS). Anecdotal reports from input companies show an increased demand for mineral supplements infused with phytogenics. The complex chemical compositions of these products appear to make them less prone to developing resistance by microorganisms. Phytogenics research has been further catalyzed by government legislation that has banned the use of medically important antibiotics to prevent the spread of antibiotic resistance. Potential improvements in livestock productivity are associated with mechanisms such as enhanced nutrient utilization, increased digestibility, modified digestive secretions or altered microbial communities. These benefits contribute to the increasing use of these phytogenics by livestock producers to keep their animals healthy and productive while enhancing the profitability of their operations. We will examine the different bioactives and their applications in improving the efficiency of the rumen function. Some commercial products in the Canadian market will be presented. Other research trials showcasing their potential benefits to rumen health and general animal productivity will also be discussed.

EXPRESS: Towards theoretically understanding how long-term memory semantics can support working memory performance.

Working memory is the system that supports the temporary storage and processing of information. It is generally agreed that working memory is a mental workspace, with a combination of resources operating together to maintain information in mind for potential use in thought and action. Theories typically acknowledge contributions of long-term memory to this system. One particular aspect of long-term memory, namely semantic long-term memory, can effectively supplement or 'boost' working memory performance. This may be a relatively automatic process via the semantic properties of the stimuli or more active via strategy development and implementation. However, the precise mechanisms require greater theoretical understanding. In this review of the literature, we critically discuss theoretical models of working memory and their proposed links with long-term memory. We also explore empirical research that contributes to our understanding of the ways in which semantics can support performance on both verbal and visuospatial working memory tasks, with a view to potential intervention development. This includes the possibility of training people with lower performance (e.g., older adults) to use semantics during working memory tasks. We conclude that semantics may offer an opportunity to maximise working memory performance. However, to realise this potential, more research is needed, particularly in the visuospatial domain.

A Collaborative Digitisation and Curatorial Project, Highlighting a Unique Collection and the Latimer Core Data Standard

Sir Joseph Banks is remembered for being a long-standing president of the Royal Society, the unofficial first director of Kew gardens and the pioneering naturalist on Captain James Cook’s great voyage onboard the Endeavour, to observe the transit of Venus and search for an undiscovered southern continent (British Museum (Natural History) 1906). Much of Bank’s life is well documented but his surviving entomology collection has never been accurately catalogued. The Banks Collection at the Natural History Museum (NHM) London is an historic assemblage of insect specimens (Fig. 1, British Museum (Natural History) 1906). It includes specimens collected by Banks and others acquired through a world-wide network of collectors. During his lifetime, Banks shared specimens with his associates and gave many specimens to Dr. William Hunter and Johan Christian Fabricius. After his death, the remaining collection was donated to the Linnean Society and later passed to the British Museum in 1863. The Banks Collection has both historical and cultural value and continues to be a relevant research tool. This is largely because Fabricius, a student of Carl Linnaeus, described many new species from the collection. Consequently, the collection contains many taxonomically important type specimens. The number of specimens in the collection is unknown but estimated to be approximately 4000. The NHM is digitising the collection with the generous support of the Charles Hayward Foundation. The collection is housed in 55 entomological glass-topped drawers, albeit not the original drawers. When conserving historical material, there is an argument to leave everything in its original state, but after much consideration, the curatorial team decided—for the long-term preservation of the collection—the specimens should be rehoused into plastazote®-lined drawers keeping the original layout of the specimens and replacing the current cork-lined drawers as part of the digitisation process. High-resolution images are taken of every specimen with its associated labels. The information on the labels is recorded for each specimen and a barcode added. As of August 2024, 3,300 specimens have been digitised and 30 of the 55 drawers recurated. More than 5000 high-resolution images have been taken (Fig. 2) and 438 labels have been transcribed for almost 1200 specimens. This project is using a new Biodiversity Information Standards (TDWG) data standard, Latimer Core, designed to support the representation and discovery of natural science collections (Woodburn et al. 2022). Latimer Core is intended to be complimentary to specimen-level standards such as Darwin Core (Darwin Core Task Group 2009), providing a way to structure and share higher-level information about groups of collection objects, from whole-museum collections through thematic and historic collections, to the contents of a single drawer. This is useful for collections with lots of associated data, fragile specimens or when displacement and disassociation of information is a concern. Unlike modern specimens, with data labels containing information on collecting event and associated persons, specimens in the Banks collection have few original labels. It was common practice that labels were temporary data storage and disposed of once the data was published. A replacement label was provided after publication (Fig. 2). The publication provides species description, geographic origin and often the name of the collection containing the specimen. Additional labels were subsequently added by curators and researchers. Many specimens have no data labels (Fig. 3). Unravelling important information about individual specimens, species and groups of specimens in this collection, including taxonomic, type status and origin will be supported by Latimer Core, as it allows a more holistic approach compared to only using specimen-level data. We can better incorporate data derived from various sources such as published data, illustrations and personal correspondence to learn about the individual and groups of specimens, the reverse of the usual workflow. Digitising this collection will improve access through digital records (specimen/drawer images, transcribed labels, publication references) reducing the need for physical examination and risk of damage. Whole-drawer digitisation in addition to specimen-level imaging provides information on the organisation and display of a collection. A collection of this nature demands minimal handling and the best storage and collections management procedures to ensure its survival for future generations. However, its significance commands a continued interest by a wide and varied audience. By digitising this collection, we will improve its physical housing, increase its accessibility without compromising the specimens for the future, and support the publication of a comprehensive catalogue of the collection.

Нейровизуализационный подход для выявления биомаркеров рабочей памяти у больных с хронической ишемией мозга

Verbal working memory (VWM) is a fundamental function responsible for temporary storage and short-term handling of verbal information. The study was aimed to determine the working memory biomarker associated with imaging of the source of infra-slow electrical activity in patients with chronic cerebral ischemia (CCI). A total of 50 patients with CCI took part in the study: 16 males and 34 females aged 50–85 years. VWM was evaluated by the Luria test. The subjects were divided into two groups matched by age with the VWM below and above the average level for the studied sample. The infra-slow, below 0.1 Hz, electrical activity, otherwise known as the DC potentials (DCPs) of the brain, was recorded with five monopolar leads: frontal, central, occipital, right and left temporal. The resting state fMRI was used to analyze brain regions with the activated BOLD (blood-oxygen-level-dependent) signal that were associated with the brain regions responsible for VWM and the DCP generation sources recorded with the non-polarizable electrodes. The differences in BOLD signal activation and infra-slow activity amplitude were found in two VWM groups. These resting-state neural networks, VWM and the neural network responsible for DCP generation, overlapped in frontal regions. There were significant differences in DCP recorded with the frontal lead in two VWM groups (р = 0.00004). In patients with CCI, infra-slow activity, recorded with the frontal lead that is generated by the neural network fragment representing an intersection of the VWM network and the part of the brain responsible for DCP generation in the frontal region, is a VWM biomarker.
