Determination of Maximum Calculated Total Values of Wind Loads on the Elements of Anti-Theft Device from Eccentric and Wedge Mechanism
Authors: Selivonchik S. M. , Nesterenko N. L. 
Published: February 2024

To carry out a power calculation of the anti-driveaway device (from now on referred to as – AD) of lifting cranes operating in the open air, it is necessary to know the maximum calculated value of the wind force on the elements of the AD rails connected by side bars. The various types of anti-theft crane devices recommended for use have a number of disadvantages, which have been written about in previous papers. Anti-theft crane devices are also known, in which the stop of lifting cranes on the rail track is carried out by a locking eccentric interacting with the surface of the rail head. The reliabi-lity of such devices is insufficient, since due to the constant force of the spring, the adhesion force of the eccentric to the rail does not depend on the changing wind force. To carry out a power calculation of the anti-theft device for cranes operating in the open air, it is necessary to know the maximum calculated value of the wind force acting on its elements that hold the cranes on the rails when the cranes are inoperative. When a crane moves along rails under the influence of wind force Pw, the eccentric, turning, transmits the pressure force from the rail to the double-arm lever connecting the eccentric mechanism to the wedge mechanism. The eccentric mechanism is essentially a drive for the vertical movement of the wedge, as a result of which the pincer clamp closes on the rail head and the crane stops. Thus, the energy developed by the crane, driven by the force Pw, is used to stop it. For this purpose, the paper deals with the issues of determining the maximum design values of the wind force acting on the total lateral surfaces of various types of cranes under different climatic, aerodynamic, probabilistic and other wind loads. A methodology is given for determining the maximum calculated total values of wind loads on the elements of the developed anti-theft device for lifting cranes moving along crane rail tracks. The calculated total lateral areas and wind loads on bridge support single- and double-girder cranes, gantry and tower cranes for various designs, spans, load capacities and other parameters have been determined. Based on the calculations performed, it is possible to create a model range of anti-theft devices for various designs of load-lifting cranes moving on crane rails under various operating conditions.

Abstract

The COVID-19 pandemic had a significant impact on virtually every human activity. Millions of workers around the globe from eligible professions stayed at home working as part of the measures taken to contain the virus’ spread. The change in transportation demand associated to this phenomenon poses a challenge for cities, especially regarding public transportation, where the decrease in demand arose critical questions on how to assess decreased ridership and potential rebound effects. With this in mind, we ask: can we obtain real-time demand change estimates using social media data? Hence, the aim of this work is to take social media unstructured information and transform it into structured insights that can offer almost real-time estimates on demand trends associated with telecommuting. To achieve this, we obtained around 50,000 geo-tagged tweets relevant to telecommuting in the US. With that, we leveraged transformers Machine Learning methods to fine-tune a language model capable of automatically assigning a sentiment to tweets on this topic. We used the time evolution of the obtained sentiments as covariates in time series forecasting models to estimate telecommuting rates at both the national and state levels, observing a drastic improvement over the estimates without such covariates. Our major finding indicates that it is possible to structure social media data in order to use it to obtain demand change estimates, and that the accuracy of such estimates is going to depend heavily on how much people discuss the topic in question in a determined geography. This finding is in line with others that have found alternative ways of obtaining insights on transportation data, and hence, is a relevant contribution towards real-time data-driven approaches for transportation demand assessment.
Mult-omics Approach-Based Autophagy Pathway Analysis in Alzheimer’s Disease
Authors: Xia Dong 
Published: February 2024

Abstract
Autophagy, as an important cellular protective mechanism, is closely associated with the occurrence and progression of neurode- generative diseases such as Alzheimer’s disease. However, the specific mechanisms underlying autophagy in neurodegenerative diseases remain unclear, and there are still many unknowns regarding its detailed regulation and involvement mechanisms. In this study, we aimed to use a multi-omics bioinformatics approach to integrate large-scale transcriptomic data and identify a series of autophagy key genes, namely CDKN2A, CXCR4, and IFNG, whose expression levels significantly differ between disease pa- tients and normal controls. Additionally, single-cell omics data will be supplemented to further investigate these findings. Our goal is to provide important clues for unraveling the pathogenesis of Alzheimer’s disease and potentially identify novel targets for future therapeutics and diagnostics. Furthermore, by incorporating Mendelian randomization analysis, we will explore the causal relationships between vascular inflammation, depression, and mood fluctuations with Alzheimer’s disease to provide insights into the associations among these related diseases and offer a theoretical basis and clinical application value for their treatment and prevention.

Abstract
Aim: This study aimed to investigate the influence of nutritional support on autophagic activity and inflammatory markers in an experimental sepsis model induced by lipopolysaccharide (LPS) in rats.
Material and Method: Thirty-five male Wistar albino rats were divided into three groups: control, LPS-induced sepsis, and LPS-induced sepsis with nutritional support. Sepsis was induced by intraperitoneal LPS administration, and nutritional support was provided via orogastric tube feeding. Sickness behavior, body weight changes, and molecular markers (NLRP3, Caspase-1, IL-1β, Beclin, LC3) were assessed.
Results: Sepsis induction led to significant weight loss and increased sickness scores, with notable changes in molecular markers. Nutritional support showed a potential influence on NLRP3 and LC3 levels, suggesting a regulatory role in inflammasome activity and autophagy during sepsis.
Discussion and Conclusion: The study sheds light on the complex interplay between sepsis, nutritional support, and molecular markers. Notably, NLRP3 exhibited significant differences, while other markers showed nuanced responses. The findings suggest a potential regulatory effect of nutritional support on the inflammatory response and autophagy during sepsis. Further investigations into temporal dynamics and specific pathways are warranted for a comprehensive understanding of these interactions, offering valuable insights for therapeutic strategies in sepsis.

Abstract

The dysregulation of the epigenetic machinery has been linked to neurodevelopmental defects in humans. One such syndrome is Kleefstra syndrome (KS), which results from heterozygous alterations in the EHMT1 gene, leading to loss of function. EHMT1 and EHMT2 are highly similar histone methyltransferases that play crucial roles in development. Despite their similarity, alterations in EHMT2 have not been previously reported. In this study, we present a pediatric patient exhibiting a phenotype overlapping with KS, harboring a de novo single base substitution in EHMT2. This substitution results in the amino acid change p.Ala1077Ser in the catalytic SET domain, causing a decrease in the affinity of this domain for histone H3 tail and a three- to five-fold reduction in enzyme activity. As part of an advanced diagnostic strategy, we leveraged epigenomics and proteomics data to comprehensively characterize the EHMT2 p.Ala1077Ser variant. Analysis of DNA methylation, histone methylation, and gene expression profiles reveals a substantial overlap between the EHMT2 p.Ala1077Ser variant and KS. Based on these findings, we propose that EHMT2 haploinsufficiency leads to a Kleefstra-like syndrome. While we cannot entirely rule out dominant negative effects caused by the EHMT2 p.Ala1077Ser variant, our data, in conjunction with previously published studies, suggest that the loss of EHMT2 function is more detrimental to cells than the loss of EHMT1. This may explain the rarity of individuals with alterations in EHMT2.
Assessment of mobility of seniors using ‘Timed Up and Go’ test and the risk of falls by means of the Tinetti test in the context of various aspects of life in a population covered by the family doctor care
Authors: Drobnik Jarosław , Roemer-Ślimak Roma , Siekierka Joanna , Grata-Borkowska Urszula 
Published: February 2024

Abstract
Background:
The latest demographic trends show that the number of elderly people will continue to grow dramatically. Mobility is extremely important for seniors because it allows them to remain independent, to participate in the lives of families and communities, and to take part in physical activities. Falls increase the frequency of hospitalization, which negatively affects patients' physical fitness. In the presented study, our goal was to assess the degree of mobility of seniors in the context of various aspects of life. The increasing prevalence of mobility limitations among seniors is a concern because it affects the quality of life of the elderly population.
Methods:
230 patients, who were under the care of a family doctor's clinic, were subject to the test. The tools used in the study were the Tinneti test and Timed UP and GO test. The start of the study was preceded by the consent of the Bioethics Committee of the State Medical Higher Vocational School in Opole No. 10/PI/2019
Results:
The results of our study indicate the existence of relationships, among others: between the status of residence or place of residence and the tendency to falls or functional mobility. The results, which were obtained in our research, cannot be compared with the results from other studies because we have not been able to find analyses on mobility of patients in the contexts we discussed.
Conclusions:
Men constitute a larger group with significant mobility restrictions. People living alone were characterized by greater physical fitness in everyday life. The high level of risk of falls is connected with limited mobility and limited motor functions of the elderly over 75 and seniors living in a village.
Sunlight-powered hovering of an ultra-light micro aerial vehicle
Authors: Qi Mingjing 
Published: February 2024

Abstract

The limited flight duration presents a significant obstacle to the widespread application of micro aerial vehicles (MAVs)1-3, especially for ultra-lightweight ones weighing less than 10 grams, generally having a flight endurance of no more than 10 minutes1,4. Sunlight power5-7 is a potential alternative to improve the endurance of ultra-light micro aerial vehicles, but owing to the restricted payload capacity of the vehicle and low lift-to-power efficiency of traditional propulsion systems, previous studies can not achieve untethered flight or sustaining hovering of MAVs powered by natural sunlight 8,9. To address the challenges, here we present a novel electrostatic-driven propulsion system with ultra-low power consumption (137 mW) and high lift-to-power efficiency (30.7 g·W-1) to realize the first sunlight-powered hovering of a micro aerial vehicle (with a total lift-to-power efficiency of 7.4 g·W-1) under natural sunlight conditions (920 W·m-2). The vehicle mainly consists of an electrostatic-driven propulsion system and an ultra-light kilovolt power system, with a total mass of 4.21 g, which is 1/600 of the existing lightest sunlight-powered aerial vehicle capable of hovering6. The sunlight-powered aerial vehicle we present is the first micro aerial vehicle to achieve untethered flight and sustained hovering under natural sunlight conditions (as opposed to artificial light sources 8,10 and wireless radiofrequency11).

Published: February 2024

Abstract

Introduction: Parents can struggle with communication with their children. This can cause stress for parents and disturb family functioning. Digital innovations could give parents a tool to relate to and strengthen interactions with their children.
Aims and objectives: This review aims to summarize previous attempts to improve communication and interactions between child and parent/guardian using digital tools and techniques.
Methods: a scoping review approach was used, applying systematic searches and screening methods in Rayyan software. The included studies were then analysed using a narrative review, mapping results onto intervention functions from the behaviour change wheel.
Results: 322 articles were screened, and seven were found to be relevant. Education, coercion, training, and enablement functions were used throughout, with mostly positive results.
Discussion: Although more research is needed, the initial results are positive. Digital innovations can prove useful in promoting communication and improving the interactions between parents and children. Future research is needed with a more varied set of techniques and functions inherent to the innovations.
Implications: Digital innovations may provide a useful, cheap and easy-to-use complement to support parents during child rearing if developed and evaluated systematically and the contents are sufficiently complex and user-friendly.
Sediment load assessments under climate change scenarios - lack of integration between climatologists and environmental modelers

Published: February 2024

Abstract

Increasing precipitation accelerates soil erosion and boosts sediment loads, especially in mountain catchments. Therefore, there is significant pressure to deliver plausible assessments of these phenomena on a local scale under future climate change scenarios. Such assessments are primarily drawn from a combination of climate change projections and environmental model simulations, usually performed by climatologists and environmental modelers independently. Our example shows that without communication from both groups the final results are ambiguous. Here, we estimate sediment loads delivered from a Carpathian catchment to a reservoir to illustrate how the choice of meteorological data, reference period, and model ensemble can affect final results. Differences in future loads could reach up to even 6,000 tons of sediment per year. We postulate there has to be better integration between climatologists and environmental modelers, focusing on introducing multi-model ensembles targeting specific impacts to facilitate an informed choice on climate information.
Perspectives of General Dental Practitioners on Restoring Endodontically Treated Molars: A UK-Based Vignette Study.
Authors: Butt Sadia , Patel Shenil , Kasperek Dariusz , Mowad Emad , Jarad Fadi 
Published: February 2024

Abstract
Aims: To assess and compare how UK general dental practitioners restore endodontically treated molars and what tooth-related factors they consider relevant to their management.
Method: An online cross-sectional vignette survey was sent out to UK dentists via email and the use of social media platforms. Three clinical cases were designed.
Results: 394 participants completed the survey. GDPs showed a preference towards restoring the endodontically treated molars with indirect restorations such as crowns and onlays. Material election varied, with a notable inclination towards gold and lithium disilicate. This was influenced by factors such as the number of remaining tooth walls, thickness of walls, and the presence of parafunction.
Conclusion: Clinicians generally agreed on whether to place a direct or indirect restoration but there was greater disagreement when deciding on the type of restoration and material. Further evidence and education are required to help UK dentists decide more objectively whether to place an onlay or a crown, what material to select, and what prognostic factors are most pertinent to the case.

Published: February 2024

Abstract
Due to growing interest in the investigation of exercise induced sweat biomarkers to assess an individual’s health and the increasing prevalence of tattoos in the world’s population, investigators sought to determine whether local sweat concentrations and excretion rates of epidermal growth factor (EGF), interleukin (IL)-10, IL-1α, IL-1β, IL-6, IL-8, tumor necrosis factor alpha (TNF-α), cortisol, glucose, blood urea nitrogen (BUN), and lactate differ between tattooed and contralateral non-tattooed skin during exercise. Sixteen recreational exercisers [female (50%)] (age = 25-48yrs) with ≥ 1 unilateral permanent tattoo [median age = 6yrs, IQR = 5] on the arm/torso completed an outdoor group fitness session. There were no significant differences between tattooed and non-tattooed skin for sweat EGF, IL-10, IL-1α, IL-1β, IL-8, TNF-α, cortisol, glucose, BUN, or lactate concentrations. There were no significant differences between tattooed and non-tattooed skin for sweat EGF, IL-10, IL-1α, IL-1β, IL-8, TNF-α, cortisol, glucose, BUN, or lactate excretion rate. Findings suggest that permanent tattoos older than 1 year may not impact local sweat EGF, IL-10, IL-1α, IL-1β, IL-8, TNF-α, cortisol, glucose, BUN, and lactate concentrations or excretion rates during exercise.

Abstract
Microplastic release from semicrystalline plastics threaten the environment and human health. We investigated polypropylene and polyethylene plastics, which together account for 54% of the global market. Mimicking common levels of residual stress found in plastics via cantilever beam experiments, we demonstrated that compressive stress drives nano and microscale segregation of amorphous polymer droplets onto the plastic’s surface. Simulations reveal this stress-driven volumetric flow is consistent with that of a Bingham plastic material, with a temperature-dependent threshold yield stress. Flow is thermally activated and stress dependent, with a reduced energy barrier at higher compressive stresses. Transfer of surface segregated amorphous droplets into the surroundings generates microplastics. Studies with water-containing plastic bottles showed that the highly compressed neck and mouth regions were predominantly responsible for the release of microplastics.
