This study aimed to progress the understanding of idiopathic hypersomnia (IH) by assessing the moderating influence of individual characteristics, such as age, sex, and body mass index (BMI) on sleep architecture. In this retrospective study, 76 IH participants (38.1 ± 11.3 years; 40 women) underwent a clinical interview, an in-laboratory polysomnography with a maximal 9-h time in bed and a multiple sleep latency test (MSLT). They were compared to 106 healthy controls (38.1 ± 14.1 years; 60 women). Multiple regressions were used to assess moderating influence of age, sex, and BMI on sleep variables. We used correlations to assess whether sleep variables were associated with Epworth Sleepiness Scale scores and mean sleep onset latency on the MSLT in IH participants. Compared to controls, IH participants had shorter sleep latency (p = 0.002), longer total sleep time (p < 0.001), more time spent in N2 sleep (p = 0.008), and showed trends for a higher sleep efficiency (p = 0.023) and more time spent in rapid eye movement (REM) sleep (p = 0.022). No significant moderating influence of age, sex, or BMI was found. More severe self-reported sleepiness in IH patients was correlated with shorter REM sleep latency and less N1 sleep in terms of proportion and duration (ps < 0.01). This study shows that, when compared to healthy controls, patients with IH had no anomalies in their sleep architecture that can explain their excessive daytime sleepiness. Moreover, there is no moderating influence of age, sex, and BMI, suggesting that the absence of major group differences is relatively robust.

Published: July 2024

Resource optimization, timely data capture, and efficient unmanned aerial vehicle (UAV) operations are of utmost importance for mission success. Latency, bandwidth constraints, and scalability problems are the problems that conventional centralized processing architectures encounter. In addition, optimizing for robust communication between ground stations and UAVs while protecting data privacy and security is a daunting task in and of itself. Employing edge computing infrastructure, artificial intelligence-driven decision-making, and dynamic task offloading mechanisms, this research proposes the dynamic task offloading edge-aware optimization framework (DTOE-AOF) for UAV operations optimization. Edge computing and artificial intelligence (AI) algorithms integrate to decrease latency, increase mission efficiency, and conserve onboard resources. This system dynamically assigns computing duties to edge nodes and UAVs according to proximity, available resources, and the urgency of the tasks. Reduced latency, increased mission efficiency, and onboard resource conservation result from dynamic task offloading edge-aware implementation framework (DTOE-AIF)'s integration of AI algorithms with edge computing. DTOE-AOF is useful in many fields, such as precision agriculture, emergency management, infrastructure inspection, and monitoring. UAVs powered by AI and outfitted with DTOE-AOF can swiftly survey the damage, find survivors, and launch rescue missions. By comparing DTOE-AOF to conventional centralized methods, thorough simulation research confirms that it improves mission efficiency, response time, and resource utilization.
Selective recovery of pyrolyzates of biodegradable (PLA, PHBH) and common plastics (HDPE, PP, PS) during co-pyrolysis under slow heating

Published: July 2024

Pyrolytic synergistic interactions, in which the production of pyrolyzates is enhanced or inhibited, commonly occur during the co-pyrolysis of different polymeric materials, such as plastics and biomass. Although these interactions can increase the yield of desired pyrolysis products under controlled degradation conditions, the desired compounds must be separated from complex pyrolyzates and further purified. To balance these dual effects, this study was aimed at examining pyrolytic synergistic interactions during slow heating co-pyrolysis of biodegradable plastics including polylactic acid (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyhexaoate) (PHBH) and petroleum-based plastics including high-density polyethylene (HDPE), polypropylene (PP), and polystyrene (PS). Comprehensive investigations based on thermogravimetric analysis, pyrolysis–gas chromatography/mass spectrometry, and evolved gas analysis-mass spectrometry revealed that PLA and PHBH decompose at lower temperatures (273–378 °C) than HDPE, PP, and PS (386–499 °C), with each polymer undergoing independent decomposition without any pyrolytic interactions. Thus, the independent pyrolysis of biodegradable plastics, such as PLA and PHBH, with common plastics, such as HDPE, PP, and PS, can theoretically be realized through temperature control, enabling the selective recovery of their pyrolyzates in different temperature ranges. Thus, pyrolytic approaches can facilitate the treatment of mixed biodegradable and common plastics.

Published: July 2024

The 3.5 mm diameter or thicker Steinmann pins were commonly used in skeletal traction, which are so highly invasive that may result in severe complications such as pin tract infection and iatrogenic calcaneus fractures. Accordingly, Xirui Wu designed a new type of tension traction bow that can be assembled with 2.0 mm diameter Kirschner wires, but its effectiveness is unclear. We aim to evaluate the effectiveness of 2.0 mm diameter Kirschner wires assembled with Wu’s Tension Traction Bows in calcaneal skeletal traction. Data of 65 patients who were admitted to our department with tibia fractures from January 2021 to June 2022 and underwent preoperative calcaneal skeletal traction were collected retrospectively. 36 patients treated with 2.0 mm diameter Kirschner wires assembled with Wu’s Tension Traction Bows were assigned into Group 1, and 29 patients treated with 3.5 mm diameter Steinmann pins assembled with Bohler’s traction bows were assigned into Group 2. Pins loosening, breakage, and calcaneus fractures occurred in neither group. No statistical differences were observed in traction weight, swelling reduction efficacy, and traction duration (P > 0.05). Statistically significant differences were found between the two groups in term of post-traction bleeding incidence, average bleeding duration, and mean size and healing time of traction wounds (P < 0.05). Though VAS pain score before traction and on the first two days after traction in Group 1 didn't differ from Group 2 (P > 0.05), it was significantly lower in Group 1 compared to Group 2 on the third day after traction (P = 0.030). This study demonstrates that 2.0 mm diameter Kirschner wires assembled with Wu’s Tension Traction Bows produce satisfied traction outcomes with less invasion and are recommended in calcaneal skeletal traction.

Indigenous goats are important to many livelihoods. Despite this, they are subjected to indiscriminate crossbreeding. This affects their genetic variability which is needed to survive in current regime of climate change. The study assessed population structure and genetic diversity of Galla and Small East African goats (SEA) using pedigree information. A total of 7384 animals, 5222 of the Galla and 2162 of the SEA breeds, born between the years 1983 and 2022, were utilized. Individuals with known parents were defined as reference population. From the results, the maximum generation traced for Galla and SEA populations was 14.6 and 14.5, respectively. However, only 6 and 5 generations for Galla and SEA were complete. Pedigree completeness increased with the increasing number of generations. The average generation interval (GI) for Galla and SEA was 3.84 ± 0.04 and 4.4 ± 0.13 years. The average increase in the rate of inbreeding per generation for Galla and SEA was 0.04 and 0.05, with the effective ancestors and founders (fa/fe) ratio being same (1.00) for both breeds. Fifty percent (50%) of the genetic variability in the populations was contributed by 3 and 1 ancestor for Galla SEA, respectively. The effective population size (Ne) was 5.19 and 4.77 for Galla and SEA. Therefore, the current breeding programs should be changed to avoid future genetic bottlenecks in this population. These findings offer an opportunity to enhance the current genetic status and management of Kenyan native goats and other regions with similar production systems.

Published: July 2024

The study of the fluid inclusions of W–Mo deposits in the mineralization area of Ningshan–Zhen’an , Shaanxi Province, China shows that the gas–liquid two-phase inclusions are mainly present in W–Mo deposits, and the ore-forming fluid can be divided into four types: high-temperature type, middle–high-temperature type, middle-temperature type and low-temperature type. The formation depths of the W–Mo mineralization range from 4.2 to 8.4 km. The boiling and mixing of fluid may have been important mechanisms for the formation of W–Mo mineralization. The skarn-type mineralization is dominated by magmatic water, the quartz-vein-type mineralization includes both magmatic water and meteoric water, and the meteoric water is more involved in the quartz-fluorite-vein-type, beryl-quartz-vein-type and pegmatite-type mineralization. Magma is the main source of sulfur; that is, magma is the main source of mineralization. Combined with the metallogenic setting and geological characteristics of typical ore deposits, in the process of structural system transformation in South Qinling, the ore-forming magma fluid in the Late Indosinian–Yanshanian period was uplifted and emplaced along the NW–WNW direction and NE–NNE direction, and eventually, NW–WNW fault-controlled skarn-type W–Mo mineralization and quartz-vein-type W–Mo deposits accompanied by greisenization, albitization and potash feldspathization formed.

Long-acting passive immunization strategies are needed to protect immunosuppressed vulnerable groups from infectious diseases. To further explore this concept for COVID-19, we constructed Adeno-associated viral (AAV) vectors encoding the human variable regions of the SARS-CoV-2 neutralizing antibody, TRES6, fused to murine constant regions. An optimized vector construct was packaged in hepatotropic (AAV8) or myotropic (AAVMYO) AAV capsids and injected intravenously into syngeneic TRIANNI-mice. The highest TRES6 serum concentrations (511 µg/ml) were detected 24 weeks after injection of the myotropic vector particles and mean TRES6 serum concentrations remained above 100 µg/ml for at least one year. Anti-drug antibodies or TRES6-specific T cells were not detectable. After injection of the AAV8 particles, vector mRNA was detected in the liver, while the AAVMYO particles led to high vector mRNA levels in the heart and skeletal muscle. The analysis of the Fc-glycosylation pattern of the TRES6 serum antibodies revealed critical differences between the capsids that coincided with different binding activities to murine Fc-γ-receptors. Concomitantly, the vector-based immune prophylaxis led to protection against SARS-CoV-2 infection in K18-hACE2 mice. High and long-lasting expression levels, absence of anti-drug antibodies and favourable Fc-γ-receptor binding activities warrant further exploration of myotropic AAV vector-based delivery of antibodies and other biologicals.

Mucosa-associated lymphoid tissue lymphoma-translocation protein 1 (MALT1) is an attractive target for the development of modulatory compounds in the treatment of lymphoma and other cancers. While the three-dimensional structure of MALT1 has been previously determined through X-ray analysis, its dynamic behaviour in solution has remained unexplored. We present here dynamic analyses of the apo MALT1 form along with the E549A mutation. This investigation used NMR 15N relaxation and NOE measurements between side-chain methyl groups. Our findings confirm that MALT1 exists as a monomer in solution, and demonstrate that the domains display semi-independent movements in relation to each other. Our dynamic study, covering multiple time scales, along with the assessment of conformational populations by Molecular Dynamic simulations, Alpha Fold modelling and PCA analysis, put the side chain of residue W580 in an inward position, shedding light at potential mechanisms underlying the allosteric regulation of this enzyme.

Mycobacteria adapt to infection stresses by entering a reversible non-replicating persistence (NRP) with slow or no cell growth and broad antimicrobial tolerance. Hypoxia and nutrient deprivation are two well-studied stresses commonly used to model the NRP, yet little is known about the molecular differences in mycobacterial adaptation to these distinct stresses that lead to a comparable NRP phenotype. Here we performed a multisystem interrogation of the Mycobacterium bovis BCG (BCG) starvation response, which revealed a coordinated metabolic shift away from the glycolysis of nutrient-replete growth to depletion of lipid stores, lipolysis, and fatty acid ß-oxidation in NRP. This contrasts with BCG’s NRP hypoxia response involving a shift to cholesterol metabolism and triglyceride storage. Our analysis reveals cryptic metabolic vulnerabilities of the starvation-induced NRP state, such as their newfound hypersensitivity to H2O2. These observations pave the way for developing precision therapeutics against these otherwise drug refractory pathogens.

Seagrasses are marine flowering plants that form extensive meadows from the inter-tidal zone up to ~50 m depth. As biological and ecological Essential Biodiversity Variables, seagrass cover and composition provide a wide range of ecosystem services. Inter-tidal seagrass meadows provide services to many ecosystems, so monitoring their occurrence, extent, condition and diversity can be used to indicate the biodiversity and health of local ecosystems. Current global estimates of seagrass extent and recent reviews either do not mention inter-tidal seagrasses and their seasonal variation, or combine them with sub-tidal seagrasses. Here, using high-spatial and high-temporal resolution satellite data (Sentinel-2), we demonstrate a method for consistently mapping inter-tidal seagrass meadows and their phenology at a continental scale. We were able to highlight varying seasonal patterns that are observable across a 23° latitudinal range. Timings of peaks in seagrass extent varied by up to 5 months, rather than the previously assumed marginal to non-existent variation in peak timing. These results will aid management by providing high-resolution spatio-temporal monitoring data to better inform seagrass conservation and restoration. They also highlight the high level of seasonal variability in inter-tidal seagrass, meaning combination with sub-tidal seagrass for global assessments will likely produce misleading or incorrect estimates.
Aridity threshold of ecological restoration mitigated atmospheric drought via land‒atmosphere coupling in drylands

Published: July 2024

Land‒atmosphere coupling intensifies the vulnerability of ecosystems in drylands. However, whether and how ecological restoration would modify the land‒atmosphere coupling across drylands remains unclear. To address these gaps, here we use structural equation model to separate two pathways of land‒atmosphere coupling: vegetation and soil moisture pathways, and investigate the effect of ecological restoration in China’s drylands on land‒atmosphere coupling. Analysis reveals that, land‒atmosphere coupling regulates approximately 30% of atmospheric drought, among which soil moisture pathway contributes twice as much as vegetation pathway. Vegetation greening mitigates atmospheric drought in areas where the aridity index ranges from 0.3 to 0.5, while soil drying exacerbates atmospheric drought in areas where the aridity index ranges from 0.5 to 0.65. The findings identify the optimal regions where ecological restoration helps alleviate the vulnerability of ecosystems under anthropogenic warming. Additionally, the proposed method enhances the understanding of how restored ecosystems contribute to mitigating atmospheric drought.

Survey of biosolar roofs in the world
Authors: Knut Pavol , Kocurkova Maria , Petkanic Stefan
Published: July 2024

In this article, we will continue our study on biosolar roofs. Biosolar roofs have become an inspiring system for us because it creates a sustainable place and reduce carbon emissions. This types roofs are different from classic green roofs in that it uses a renewable source of energy, in this case the Sun, and produce electricity that we can supply the building with. What is interesting is that the vegetation stored under the photovoltaic panels can use evaporation to cool the panels and therefore increase their efficiency. We know from the world that biosolar roofs are not so widespread due to implementation factors such as initial costs and limited experimental data. It is very important that new experimental studies be carried out to evaluate the performance of this system in urban areas. Another important factor that should not be forgotten is location of the system. It is necessary to know all climatic conditions before implementing the system. In this article, we will focus on the benefits of this type of roofs and how the system can improve the energy efficiency of photovoltaic panels and reduce CO2 emissions with long-term benefits.
Information model of the building and its application in selected phases of the life cycle

Published: July 2024

Despite various aspects, be it social or economic, construction is considered one of the decisive industries in many countries. In this industry, it is not possible to automate and streamline processes like for example in the automotive industry, as each construction work is unique every time. However, by implementing modern technologies of the 21st century, it is possible to streamline the processes in the pre-investment, investment and especially in the phase of using the construction work. Since the construction work is supposed to be used and functional for several decades. A suitable tool is the use of the building information model in short - "BIM". This issue has been moving and progressing significantly in recent years. By implementing these digital technologies in construction projects, it is possible to significantly speed up the course of construction, avoid collision situations, save financial resources, and last but not least, when creating a high-quality model, it is possible to create a digital twin of a given construction work, which can significantly optimize and streamline processes right in the use phase. It is in this phase of the life cycle that there is the greatest scope for using the completed building model, which of course must be revised during the first two phases to make it as accurate as possible and usable for management and maintenance. During this phase, it is also appropriate to implement software tools such as Computer Aided Facility Management (CAFM).

In the current turbulent development of prices of building materials as well as banking products and availability of housing, Slovakia is facing significant problems with housing shortage, which is also addressed by foreign countries in the form of rental housing. According to Eurostat data for 2021, the ratio of rental housing in Slovakia to the total number of dwellings is the second lowest in the European Union at 7.1%, while this is mainly rental housing in properties owned by private landlords. The Act on State Support for Rental Housing sets maximum rent levels for individual regions of Slovakia, which directly affect the costs associated with construction. The paper shows that there is great potential of volumetric modular construction to solve increasing demand for rental housing. This article analyses the current state of adoption of modular construction abroad and in Slovakia by the good practice review and literature research resources review.
Deformation characteristics of asphalt mixtures

Published: July 2024

Asphalt pavement is among the most widespread road surfaces. For their design, assessment, and service life, it is necessary to evaluate the deformation characteristics of asphalt mixtures, which include the complex modulus of rigidity. Two-point (2PB-TR) and four-point (4PB-PR) flexural tests are used to determine these. The scientific paper focuses on the evaluation of the complex modulus as a function of varying temperature and frequency. The results of the study indicated that both methods provide significant information on the behaviour of asphalt mixtures under different loading conditions. Four-point bending may be more sensitive to changes in deformation properties than two-point bending. This finding is of fundamental importance when analysing the influence of different factors on the mechanical properties of asphalt mixtures. Measurements were performed at temperatures of 0°C, 10°C and 20°C and frequencies of 1 Hz, 5 Hz, 10 Hz, 15 Hz and 20 Hz. Validation of the different measurement methods was carried out on the comparison asphalt mix AC 11 O PMB 45/80-75.

Authors: Vargova Alena , Vertal Marian
Published: July 2024

"Wetlands are among the most productive ecosystems that retain water, protect against floods, support biodiversity, purify water, retain nutrients, and stabilize local climate conditions. Based on the advantages of natural wetlands, constructed wetlands are created and often used for grey water treatment, called eco-purifiers or root purifiers. Because of the need to use the land space for other purposes, the idea of placing a wetland on the roof has been considered. The paper presents the wetland roof as a special variant of the green roof. It focuses on three wetland roofs that were created as part of the greenIZOLA project in Slovakia over the last two years. Moreover, it summarizes the knowledge gained from the operation of the wetland roof in the climatic zone of Slovakia."

Deep Learning in Automated Short Answer Grading: A Comprehensive Review
Authors: Chaudhari Rupal , Patel Manish
Published: July 2024

Automated Short Answer Grading (ASAG), more generally referred to as ASAG, is a method that evaluates the written short answers provided by students through the use of certain computer algorithms. This particular component of ASAG has been the subject of study for a considerable amount of time [4]. A significant obstacle in ASAG is the low availability of relevant training data inside the domain. This is one of the most significant obstacles. There are a number of different approaches that may be taken to address this problem. These approaches can be broadly classified into two categories: traditional methods that rely on handcrafted characteristics and Deep Learning-based approaches [22]. Over the course of the past five years, there has been a significant increase in the number of researchers in this field that have adopted Deep Learning techniques in order to address the ASAG challenge [6]. The purpose of this research is to determine whether or whether strategies based on Deep Learning are superior to traditional methods across 38 different publications. Additionally, the study intends to provide a full review of the many deep learning methodology that have been investigated by academics in order to address this issue [19]. In addition to this, the study provides an analysis of a number of state-of-the-art datasets that are ideal for ASAG tasks and makes recommendations for evaluation metrics that are suitable for regression and classification situations.

This study, titled “Chronicles of the Midnight Strain: Exploring Graveyard Shift Stress and Its Impact on Employee Burnout in Call Centers,” delves into the intricate relationship between the demanding nature of graveyard shift work in call centers and its potential consequences on employee burnout. The research adopts a comprehensive approach, investigating various factors such as electronic performance monitoring, job demands, physiological indicators, and the role of lifestyle factors in cardiovascular health.

Drawing from a vast array of literature, the study explores the causal links and mechanisms of action, emphasizing the significant role of sleep disruption and circadian rhythm desynchronization in contributing to cardiovascular disease among shift workers. Additionally, it considers the impact of stress, working hours, and dietary patterns on the overall well- being of employees working during the unconventional hours of the night. The study reviews existing theories proposing connections between shiftwork, sleep loss, and cardiovascular diseases. It scrutinizes factors like inflammation, blood coagulation, cardiac autonomic function, and the interplay between stress-related hormones and cardiovascular health. Multiple hypotheses are examined, including the influence of a stressful work environment, disturbed sleep on the immune system, and lifestyle factors such as dietary habits and substance use.

Despite over two decades of continuous research, the findings in this area remain inconclusive regarding the precise role of shiftwork in cardiovascular disease. The study aims to contribute valuable insights into mitigating the potential adverse effects of graveyard shift stress on employee burnout in call centers, providing a foundation for further research and the development of targeted interventions.
Traitement chirurgical d’une entorse grave du grasset
associée à une luxation coxo-fémorale sur le membre controlatéral

Published: July 2024

Les traumatismes à haute énergie sont fréquemment responsables de luxation de la hanche et plus rarement du grasset. Sur un animal accidenté, une réanimation médicale est nécessaire avant de s’intéresser aux lésions orthopédiques.

Cette étude de cas décrit la prise en charge d’une luxation coxo-fémorale associée à une entorse grave du grasset sur le membre controlatéral chez un chien adulte de grand format.

Les luxations coxo-fémorales sont les luxations les plus fréquemment retrouvées dans l’espèce canine. La direction la plus classique est crânio-dorsale. Des radiographies de hanche sont indispensables pour préciser les lésions, le pronostic et le traitement par réduction orthopédique à foyer fermé, ou à foyer ouvert, associée ou non à une stabilisation.
Les luxations du grasset (ou entorse grave) sont peu fréquentes. Il faut objectiver l’étendue des lésions ligamentaires, méniscales et capsulaires. Le traitement est uniquement chirurgical et systématiquement recommandé.

Dans le cas présenté, le choix du traitement chirurgical a été dicté par l’importance des lésions articulaires et par l’atteinte simultanée des deux membres pelviens pour un retour à une fonction précoce. Pour l’articulation coxo-fémorale, une réduction à foyer ouvert associée à une stabilisation par prothèse était primordiale pour assurer une solidité du montage et pour s’adapter au report de poids sur ce membre, en raison des lésions importantes sur le genou controlatéral. Pour le grasset, une reconstruction minutieuse complétée par des ligamentoplasties a donné de très bons résultats lors du suivi au long terme du chien.
