Published: December 2023

Background: Glioblastoma remains a challenging brain tumor to treat due to its infiltrative nature. Accurately identifying tumor boundaries during surgery is crucial for successful tumor resection. This study introduces an innovative intraoperative visualization method utilizing a surgical fluorescence microscope to precisely locate tumor cells. The focus of the study is on IR-Glint, a novel preparation comprising Cy7.5-labeled aptamers Gli-233nt and Gli-55_3L specific to human glioblastoma. Methods: The aptamers were modified using molecular modeling and quantum chemical techniques. The effectiveness of the preparation was assessed using flow cytometry and microscopy on primary cultures of human glioblastoma. In vivo studies were conducted on mouse and rabbit models, employing orthotopic xenotransplantation of human brain glioblastoma with various imaging techniques, including PET/CT, in vivo fluorescence visualization, confocal laser scanning, and surgical microscopy. Results: The experiments validated the potential of IR-Glint for intraoperative visualization of glioblastoma using infrared imaging. Surface application of the aptamer-based formulation on the brain allowed clear visualization of the tumor, aiding surgeons in tumor resection. This approach also reduces the dosage required and mitigates potential toxic effects on the patient. Conclusions: This study demonstrates the promising potential of using in-frared dye-labeled aptamers for intraoperative visualization of glioblastoma. By improving surgical treatment outcomes in neurosurgery, this novel approach may pave the way for future advancements in the field.

Published: December 2023

The present study aimed to examine the stereoselective pharmacokinetics of racemic ketamine in dogs at low dose. Secondary aims were to identify associated behavioural side effects and propose a ketamine infusion rate. The study was conducted on nine intact male beagles, with each dog undergoing two treatments (BOL and INF). For treatment BOL, a single intravenous bolus of 1 mg/kg racemic ketamine was administered over 2 minutes. The treatment INF involved an initial bolus of 0.5 mg/kg given over 1 minute, followed by an infusion at 0.01 mg/kg/min for 1 hour. Blood samples were collected from the left cephalic vein for pharmacokinetic analysis. The median R/S enantiomer ratio of ketamine remained close to 1 throughout the study. However, levels of S-norketamine were significantly higher than those of R-norketamine across all time points. Based on the collected data, the infusion rate predicted to achieve a steady state racemic ketamine plasma concentration of 150 ng/mL was 1.7 mg/kg/h. Furthermore, employing ROC curve analysis, a racemic ketamine plasma concentration of 102 ng/mL was defined as the cut-off value, correlating with the occurrence of undesirable behavioural patterns.

A Kinetic Study of a Photo-Oxidation Reaction between α-Terpinene and Singlet Oxygen in a Novel Oscillatory Baffled Photo Reactor
Authors: Chen Jianhan , Prinsloo Rohen , Ni Xiongwei
Published: December 2023

By planting LEDs on the surfaces of orifice baffles, a novel batch oscillatory baffled photoreactor (OBPR) together with polymer-supported Rose Bengal (Ps-RB) beads are used to investigate reaction kinetics of a photo-oxidation reaction between α-terpinene and singlet oxygen (1O2). In the widely used NMR data analysis for this reaction, α-terpinene and ascaridole are treated as a reaction pair, assuming kinetically singlet oxygen is in excess or constant. We have, for the first time, examined the validity of the method, discovered that increasing α-terpinene initially leads to an increase of ascaridole, indicating that the supply of singlet oxygen is in excess. Applying kinetic analysis, a pseudo first order reaction kinetics is confirmed, supporting this assumption. We have subsequently initiated a methodology of estimating the 1O2 concentrations based on the proportionality of ascaridole concentrations with respect to its maximum under these conditions. With the help of the estimated singlet oxygen data, the efficiency of 1O2 utilization and the photo efficiency of converting molecular oxygen to 1O2 are further proposed and evaluated. We have also identified conditions where further increase of α-terpinene has caused decreases in ascaridole, implying kinetically that 1O2 has now become a limiting reagent, the method of treating α-terpinene and ascaridole as a reaction pair in the data analysis would no longer be valid under those conditions.
Dynamic Correlations in Disordered Systems: Implications on High-Temperature Superconductivity
Authors: Egami Takeshi
Published: December 2023

Liquid and gas are distinct in their extent of dynamic atomic correlations; in gas atoms are almost uncorrelated whereas they are strongly correlated in liquid. This distinction applies also to electronic systems. Fermi liquids are actually gas-like, whereas strongly correlated electrons are liquid-like. Doped Mott insulators share characteristics with supercooled liquids. Such distinctions have important implications on superconductivity. We discuss the evolution of dynamic atomic correlations in liquid with temperature, and a possible effect of dynamic correlations on the high-temperature superconductivity in the cuprates.
Demystifying the Factors Contributing to Alienation and Fostering Social Justice in Higher Education: A Case of First-Year University Students
Authors: Zitha Innocent , Mokganya Georgina Mokgaetji , Tshililo Takalani Yolanda
Published: December 2023

On entering higher education, students from disadvantaged schools seem unable to cope with new academic demands and all too often the need for adjustment is attributed to under-preparedness. The purpose of this paper is to identify the factors contributing to and mitigating the alienation of students in institutions of higher learning. The narrative inquiry with a qualitative method was employed to obtain the perceptions of 51 selected first-level science university students on their experiences. This is a case of the University of Venda first-year level students registered in the 2023 academic year. The findings of this paper build on and contribute to the literature on understanding alienation in higher education. In particular, the key findings of this paper reveal that the students failed to quickly adapt to a different culture of teaching and learning; the academic workload was overwhelming, and lecturers were unapproachable Students from previously disadvantaged backgrounds especially struggled to assimilate into the new university culture of teaching and learning. This paper concludes by recommending that there is a serious need to take cognisance of the influx of previously disadvantaged students into institutions that were not created with them in mind. Universities and their teaching staff should recognise the culturally diverse nature of the student body and thereby restructure teaching and assessment to foster social justice to promote student success.
A Dynamic Prediction Framework for Vitality of Urban Public Space - From hypothesis to algorithm and verification
Authors: Liu Yue , Guo Xiangmin
Published: December 2023

Predicting and evaluating the vitality level of public spaces of urban design is crucial before new construction and renewal, especially for developing countries, to avoid failures like "ghost neighborhood" and reduce resource waste. However, existing assessment methods for the urban vitality are either static and ignore changes in the time dimension, or rely on historical big data and are unable to predict unbuilt projects. This study combines previous methods and crowds’ characteristics observation in public space, puts forward the crowd-frequency hypothesis and constructs an algorithm, and establishes a time-dimensional urban vitality dynamic prediction model. Taking the Rundle Mall neighborhood in Adelaide, Australia, as an example, the effec-tiveness of the prediction model was proved through on-site observation sampling comparative verification method. In addition, the decision tree model was used to conduct machine learning on the case data, and a set of algorithm programs were obtained that can directly input some basic information to obtain the urban vitality level (high-medium-low) in a certain period. It can be used as a tool to support the design and decision-making processes of urban planners and government officials, providing a low-cost way to achieve sustainable urban vitality construction of late-developing cities directly.

With the continuous update of gene editing technology, great progress has been made in livestock breeding, researchers have produced gene edited pigs, cattle, sheep and other improved livestock. Gene editing technology is a genetic means to knock in, knock out, delete, inhibit, activate or replace specific bases of DNA or RNA sequences at the genome level to achieve accurate modification, and can edit genes at a fixed point without the need for DNA templates. In recent years, although regular clusters of interspaced short palindromic repeats (CRISPR)/Cas9 system mediated gene editing technology has been widely used in animal genetic breeding research, but so far, the system's precise insertion efficiency of foreign genes is not high enough, and there are certain off-target effects, and it is not enough to be used in genome editing of large livestock such as cashmere goats. In this paper, the development status, challenges, application prospects and look into the distance of CRISPR/ Cas9-mediated precisiongene editing technology in livestock breeding were reviewed, in order to provide theoretical reference for livestock gene function analysis, genetic improvement and livestock breeding with local economic characteristics.
Evidências sobre o prêmio salarial masculino do casamento e da coabitação no Brasil
Authors: Guiginski Janaína , Wajnman Simone , Chein Flávia
Published: December 2023

O objetivo principal é analisar a associação entre o casamento e a coabitação e o rendimento do trabalho masculino no Brasil. O artigo discute o fenômeno do “prêmio salarial masculino do casamento” - geralmente, homens casados apresentam rendimentos mais elevados do que os solteiros no mercado de trabalho. Tendo em vista que no Brasil a união informal é uma modalidade conjugal bastante comum, o prêmio para a coabitação também é investigado nessa situação. A associação entre o estado conjugal e o trabalho remunerado dos homens brasileiros é analisada por meio de regressões lineares, quantílicas e decomposições de Oaxaca-Blinder para os diferenciais de rendimentos entre os homens solteiros, casados e coabitantes. O Censo Demográfico de 2010 é a fonte de dados utilizada. Os resultados confirmam a existência de prêmios do casamento e da coabitação para os homens brasileiros. Os prêmios observados tendem a ser menores para a coabitação do que para o casamento. As decomposições dos diferenciais de rendimentos mostram que os prêmios devem-se à estrutura salarial e não a efeitos de composição.

Published: December 2023

The paper describes an integrated approach to the design and technological support of enhanced performance of turbo-expander power plants. An analysis of the current state of development of turboexpander power plants has made it possible to establish that traditional approaches have largely exhausted the possibilities of improving their technical characteristics. Moreover, a situation is emerging where, in order to ensure the improvement of such characteristics, it is necessary to involve not isolated design or technological measures, but joint design and technological measures. To implement this approach, the method of generalized parametric modeling is used. At the same time, by combining design and technological parameters, the parametric space in which to search for rational technical solutions for turbo-expander power plants is expanded. This expansion of the parametric space makes it possible to increase the efficiency of the final solution. Such a solution cannot be achieved through design or technological measures alone. The developed approach is implemented in the form of a sequence of solved stages. First, it is a study of the working processes of gas dynamics, heat and mass transfer, and power generation in turboexpander power plants. Secondly, it is the optimization of technological operations for strengthening the elements of these plants. Thirdly, it is the development of real samples of turbo-expander power plants with improved technical characteristics. In general, these stages, which are carried out in a coordinated manner on the basis of the developed generalized parametric approach, made it possible to increase the durability of turboexpander elements by 25-40 % and ensure the efficiency of the detander at the level of 86 %.

A Novel Method to Predict the Permeability of Heterogeneous Sandstones Using Multiple Echo Spacing NMR Measurements
Authors: Xiao Yufeng , Wang Hongyan , Jiang Zhenxue , Ge Xinmin , Zhang Renxia , Song Fangle , Liu Jianyu
Published: December 2023

We propose a novel method for estimating the permeability of heterogeneous sandstones based on the nuclear magnetic resonance (NMR) data with multiple echo spacings. The decaying curves and their corresponding spectra are obtained for different echo spacings to investigate the relaxation property, the diffusion term, and the signal loss contributed by higher echo spacing. Moreover, an empirical model is developed to correlate permeability with the differential decay rate. The result shows that the geometric transversal relaxation time is positively related to echo spacing, which disobeys the traditional cognition. Moreover, the absolute value of the differential decay rate is positively correlated with the echo spacing and exhibits a power law behavior. More interestingly, it is observed that the permeability diminishes in a power law behavior with respect to fitting parameters. This marks the first attempt to establish a relationship between the permeability and NMR data with different echo spacings, which is hopeful to be extended to other complex reservoirs with the availability of multiple echo spacing data.

Objetivo. Analizar la representación de los migrantes en documentos de políticas públicas (PP) en México en el marco de la pandemia de Covid-19. Material y métodos. Se utilizó el marco analítico “¿Cuál es el problema representado?” para el análisis discursivo de documentos de PP (migración y Covid-19) emitidos entre marzo de 2020 y febrero de 2022. Resultados. Los migrantes se representan como personas en tránsito, movilizándose en “caravanas” y concentrados en albergues y estaciones migratorias. Se enfatiza su “vulnerabilidad”, no se reconocen sus capacidades de agencia y se propone a los albergues como el sitio principal de la respuesta. Conclusiones. El análisis discursivo sirve como herramienta para identificar la forma en que se representa un problema y sus consecuencias. En el caso de la migración es necesario reconocer la complejidad del fenómeno en las PP (salud y migración) sin invisibilizar los diferentes grupos móviles.

Published: December 2023

Objective. To compare Covid-19 risk factors, self-reported Covid-19 testing and infection, and Covid-19 vaccination among H-2A workers and agricultural workers without H-2A visas. Materials and methods. Farmworkers completed surveys at randomly selected sites in five U.S. states from March – August 2022. Descriptive statistics and bivariate analyses were conducted for key characteristics and outcomes. Results. A total of 532 H-2A workers and 748 non-H-2A workers participated in the surveys. H-2A workers had significantly higher Covid-19 primary vaccine series uptake than non-H-2A workers (94.7 vs. 65.9%). More than one in four H-2A workers (29.6%) continued working while ill or positive with Covid-19. Fewer H-2A than non-H-2A workers reported receiving a Covid-19 test (51.5 vs. 59.2%, respectively) and a positive test result for Covid-19 (24.5 vs. 44.9% among those tested). Conclusions. Although H-2A workers had a lower self-reported prevalence of Covid-19 and higher Covid-19 primary vaccine series uptake than non-H-2A workers, findings such as reporting to work while ill or positive for Covid-19 indicate areas for improvement by binational public health leaders.

Se entrevistó a migrantes en tres ciudades de Colombia-Cúcuta, Barranquilla y Santa Martha–, San José Costa Rica y Santiago de Chile y se analizó (1) si el estado de salud difiere según la ciudad y los cambios en la AS antes y después de migrar, y (2) en qué medida el perfil sociodemográfico, el tipo de empleo y el nivel educativo están asociados con la AS. Se estimaron modelos de regresión ordinal y logística para identificar los factores asociados con la AS y a los cambios en la misma. Resultados. Se observan diferencias significativas por sexo, ocupación y entre ciudades, así como una mayor probabilidad de deterioro entre las mujeres, quienes están fuera de la fuerza de trabajo y quienes reportaron diversas enfermedades preexistentes. Conclusiones. Se enfatizan desventajas en la AS respecto a tipo de empleo de los migrantes, no así con la educación. Las diferencias entre países de acogida pueden estar asociadas con las particularidades en la gestión migratoria, políticas de integración y acceso a la salud.
Deep integration and GVC participation in developing countries: the role of investment provisions in PTAs
Authors: Delera Michele
Published: December 2023

Joining and upgrading in GVCs is a priority for developing and emerging economies. PTAs can serve as a policy tool to promote GVC participation. PTAs can mitigate the contractual frictions which affect trade in GVCs by paving the way for deeper forms of integration. In this paper, I ask whether one specific class of PTA provisions – legally enforceable investment provisions going beyond the TRIMS agreements – increase trade in customized inputs between industrialised and developing economies. Using a structural gravity approach and data on gross trade flows from BACI during the 1995-2018 period, I find that this is indeed the case. Investment provisions in PTAs tend to increase the flow of these goods between the Global North to South by between 15 and 20 percent. These results are driven by the role of investment provisions in PTAs in bridging institutional gaps in lower-income economies.

Authors: Prudente Lucas Rhaun , Leal Elisangela Martins , Santana Claudio Marcio
Published: December 2023

The effective management of waste tires poses a critical and urgent challenge in today's environmental landscape. These discarded tires endure an astonishing degradation period of approximately 600 years, emphasizing the need to urgently adopt techniques that expedite this process in an environmentally responsible manner to protect our planet. Tackling this issue involves exploring the conversion of waste tires into diesel fuel, a promising solution to mitigate the problem. Achieving sustainable progress requires a keen focus on the energy and exergy efficiency of systems, crucial aspects in this endeavor. Therefore, this study is dedicated to a comprehensive and sustainable assessment that compares conventional petroleum-derived diesel (diesel oil) with pyrolytic oils derived from rubber waste, inoperable tires, and Eucalyptus urograndis wood. These oils are intended for use in compression ignition internal combustion engines. The methodological framework of this work involves an in-depth exploration encompassing energy, exergy, and environmental analyses in a steady-state context. Using the Diesel RK software, combustion is simulated with fuel specifications sourced from established literature. The investigation is conducted within a Scania diesel stationary engine under varying scenarios. First, blends of tire pyrolysis oil (TPO) and diesel are examined, specifically in proportions of 10% TPO and 90% diesel, followed by 20% TPO and 80% diesel. Second, mixtures of Eucalyptus urograndis pyrolytic bio-oil (EPO) at ratios of 10% EPO and 90% diesel, as well as 20% EPO and 80% diesel, are considered. Lastly, the study examines the performance of conventional commercial diesel fuel. Through meticulous analysis, discernible outcomes emerge, revealing the energy and exergy performance characteristics. Notably, the parameters studied indicate a notable resemblance between diesel and TPO10 across all cases, with TPO10 emerging as the frontrunner in these analyses, closely followed by TPO20. Moreover, the study incorporates a sustainability perspective, highlighting opportunities for improvement, ecological metrics, and the emission profile of pollutants.

Then, by event-triggered scheme and Lyapunov direct method, the formation control algorithm is presented to achieve bounded of the formation error systems. Moreover, according to the event-triggered schemes, the Zeno behaviors are avoided by giving the lower bound. Finally, the validity of the result given is illustrated by a numerical example.
Above- and below-ground responses to grazing in alpine grasslands: insights from carbon allocation and dynamic in plant-soil-microbe system
Authors: Xiang Mingxue , Wu Junxi , Duo Lha , Niu Ben , Pan Ying , Zhang Xianzhou
Published: December 2023

Aims
Grazing is a widely utilization of natural grasslands globally, yet the impacts of grazing intensity on the short-term carbon (C) cycling dynamics between above- and below-ground remain inadequately understood.
Methods
we employed an experiment to identify how these changes under grazing intensities (non-grazing, NG; moderate grazing, MG; and heavy grazing, HG), which combined with an in-situ 13C tracing between plant tissues and soil microbes in alpine grassland.
Results
13C was rapidly detected in shoots, roots, soils, and microbial PLFAs after first day of pulse labeling day. Comparison to NG, the root δ13C values were significantly higher under MG than under HG during the chase period (p < 0.01). PLS-PM revealed that MG significantly enhanced the 13C allocation from shoots to roots (p < 0.05), while leading to a significant decrease in the turnover of root 13C into microbial PLFA 13C amount and 13CCr (p < 0.05), and a significant reduction in soil 13C turnover into microbial 13CCr (p < 0.05). HG significantly enhanced the turnover of soil 13C into PLFA 13C amount (p < 0.05), resulting in a significant improvement in microbial PLFA 13C amount turnover into microbial 13CCr (p < 0.05), and leading a significant decrease in root 13C turnover into microbial 13CCr (p < 0.05).
Conclusions
Grassland under MG maintains high C retention between shoots and roots, forming a strong negative cascading relationship with microorganisms in the rhizosphere, but HG enhances the utilization of rhizodeposits by microbes, establishing a strong positive cascade relationship.
Error Modeling and Accuracy Analysis of Shipborne Radar Measurement Signal Processing
Authors: pan jianghuai
Published: December 2023

Using the method of combining theoretical modeling and digital simulation, the error of each chain involved in the measurement and processing of shipborne radar was analyzed, and the error model of each chain such as radar measurement, coordinate transformation, platform attitude positioning and baseline transformation was established. Based on the first-order Taylor expansion, the approximate analytical expression of error chain linearization is given, and the equivalent error model of shipborne radar measurement is established. Theoretical analysis and computer simulation results show that the errors caused by radar azimuth measurement, platform heading and deck heading deformation can be directly added to the azimuth and combined into the azimuth error; at the same time, when the target elevation angle is less than 10 degrees, the influence of deck deformation and platform attitude error on target azimuth measurement can be almost ignored.
Emotional fit in ratings versus language: A study of the emotional experiences of Dutch-speaking Belgians and Turkish migrants in Belgium
Authors: Şencan Rüya Su , Mesquita Batja , Hoemann Katie
Published: December 2023

When two or more people have the same emotion in relation to a situation, they are making meaning of it in the same way. Previous research has shown that the extent to which immigrant minorities share similar emotions with the receiving majority culture – termed ‘emotional fit’ – may bring better integration outcomes. Emotional fit is typically measured by comparing immigrants’ self-reported emotion intensity ratings to those of the average majority culture, at the expense of other aspects of emotion that might be relevant for meaning-making. To address these shortcomings, we implemented an alternative measure of emotional fit using natural language descriptions of emotional experience. Dutch-speaking Belgians and Turkish migrants in Belgium (Ns = 100) were interviewed about four recent emotional situations, two negative and two positive, for each one rating the intensity of their experience on a set of standardized emotion terms. Patterns of language used in the situation descriptions were more effective than patterns of intensity ratings in distinguishing between cultures, such that people fit better with their own culture than with the other, regardless of whether this was assessed within- or between-persons. Language- and rating-based fit measures were not positively correlated; rather, Turkish migrants’ rating fit with Belgian culture was negatively related to their language fit in negative situations, suggesting that even when they felt the same emotions, they were attending to different aspects of the experience. Future research is needed to further disentangle culture-specific patterns of emotional meaning-making and their implications for relevant outcomes for immigrant minorities.

In this paper we develop the parametrix approach for constructing the heat kernelon a graph G. In particular, we highlight two specific cases. First, we considerthe case when G is embedded in a Eulidean domain or manifold \Omega, andwe use a heat kernel associated to \Omega to obtain a formula for the heat kernelon G. Second, we consider when G is a possibly infinite subgraph of a larger graph \widetilde{G}, and we obtain a formula for the heat kernel on G from the heat kernel on \widetilde{G} restricted to G.

Published: December 2023

The aim of this work is to introduce an adaptable framework for Multi-Objective Optimization (MOO) in Metal Additive Manufacturing (AM). The framework accommodates diverse design variables and objectives, enabling iterative updates via Bayesian optimization for continuous improvement. It employs space-filling design and Gaussian Process regression for high-fidelity surrogate models. A Sensitivity Analysis (SA) measures the input contributions. Multi-Objective Optimization (MOO) was performed using an evolutionary algorithm. Using literature data, the framework optimizes the surface roughness (SR) and porosity of the AM part by controlling the laser parameters. The GP model achieves cross-validation with an R² of 0.79, and with low relative mean errors. SA highlights the dominance of hatch distance in SR prediction and the balanced influence of laser speed and power on the porosity. This framework promises significant potential for the enhancement of AM technology.
Genotype and ginger (Zingibar officinale) rhizome powder dietary supplementation affect egg quality indices of aged layer chickens
Authors: Ogbu Cosmas C.
Published: December 2023

The study evaluated the effect of genotype and dietary ginger supplementation on egg qualities of aged Shaver brown (SB) and Nigerian heavy ecotype native (HEN) hens. Control (basal diet) groups received layer ration while supplemented (ginger diet) groups received 20g ginger/kg basal ration. Hens were fed 125g/bird/day of the experimental rations. Water was given ad libitum. 80 and 40 eggs were collected from SB and HEN basal diet groups, respectively while 80 eggs/genotype were collected from the ginger diet groups for determination of egg qualities. Egg, yolk, albumen and shell weights (EW, YW, AW and SW); egg length (EL), surface area (ESA), volume (EV), specific gravity (ESG) and shape index (ESI); egg, yolk and albumen diameters (ED, YD and AD); yolk and albumen heights (YH and AH); yolk, albumen, and ratios (YR, AR, SR) and indexes (YI, AI and SI); yolk:albumen (Y/A), Haugh unit (HU); and shell thickness (ST), volume (SV), density (SD) and compression fracture force (SCFF) were determined. Within genotypes, eggs were graded by weight and shape index and compared for quality indices. Main and interaction effects were evaluated by Two-way Analysis of Variance (ANOVA). Shape index grades in SB and weight grades in SB and HEN were compared by One-way ANOVA while shape index grades in HEN were compared by the Student’s T-test. Significant differences were accepted at p ≤ 0.05. Eggs from SB had higher EW, EL, ED, ESA, EV, ESI, YW, AW, AH, AD, AR, SW, SV, SCFF, HU, and Ca but lower ESG, YR, Y/A, Zn and P than HEN eggs. Within genotypes, ginger groups had higher EW, EL, ESA, EV, YW, YD, YR, AH, AI, Y/A, and Zn, but lower ESG, YH and YI compared to basal diet groups. Genotype x diet affected AD (SB-ginger group ˃ basal diet groups ˃ HEN-ginger group), Zn (HEN-ginger group ˃ SB-ginger group ˃ basal diet groups), and P (HEN-ginger group ˃ HEN-basal diet group ˃ SB-diet groups). Egg weight grades differed significantly in EW, ESA, ESG, ESI and SCFF in SB and HEN while shape index grades differed significantly in ESI and Y/A in SB but in ESI, YI and HU in HEN. Overall, genotype, diet, genotype x diet, and weight and shape grades influenced some of the egg quality traits.

Affective states are reflected in the facial expressions of all mammals. Facial behaviors linked to pain have attracted most of the attention so far in non-human animals, leading to the development of numerous instruments for evaluating pain through facial expressions for various animal species. Nevertheless, manual facial expression analysis is susceptible to subjectivity and bias, is labor-intensive and often necessitates specialized expertise and training. This challenge has spurred a growing body of research into automated pain recognition, which has been explored for multiple species, including cats. In our previous studies, we have presented and studied artificial intelligence (AI) pipelines for automated pain recognition in cats using 48 facial landmarks grounded in cats' facial musculature, as well as an automated detector of these landmarks. However, so far automated recognition of pain in cats used solely static information obtained from hand-picked single images of good quality. This study takes a significant step forward in fully automated pain detection applications by presenting an end-to-end AI pipeline that requires no manual efforts in the selection of suitable images or their landmark annotation. By working with video rather than still images, this new pipeline approach also optimises the temporal dimension of visual information capture in a way that is not practical to preform manually. The presented pipeline reaches over 70% and 66% accuracy respectively in two different cat pain datasets, outperforming previous landmark-based approaches using single frames under similar conditions, indicating that dynamics matter in cat pain recognition. We further define metrics for measuring different dimensions of deficiencies in datasets with animal pain faces, and investigate their impact on the performance of the presented pain recognition AI pipeline.

Authors: Santos Emanuel Alexandrino José , Lima Kleuton Antunes Lopes , Junior Luiz Antonio Ribeiro
Published: December 2023

The category of 2D carbon allotropes has gained considerable interest due to its outstanding optoelectronic and mechanical characteristics, crucial for various device applications, including energy storage. This study uses density functional theory calculations, ab initio molecular dynamics (AIMD), and classical reactive molecular dynamics (MD) simulations (ReaxFF) to introduce TODD-Graphene, an innovative 2D planar carbon allotrope with a distinctive porous arrangement comprising 3-8-10-12 carbon rings. TODD-G exhibits intrinsic metallic properties with a low formation energy and exhibits stability in thermal and mechanical behavior. Calculations indicate a substantial theoretical capacity for adsorbing Li atoms, revealing a low average diffusion barrier of 0.83 eV. The metallic framework boasts excellent conductivity, positioning TODD-G as an active layer for superior lithium-ion battery efficiency. Charge carrier mobility calculations for electrons and holes in TODD-G surpass those of graphene.

Orchideen sind wahre Verführungskünstler: Um gezielt die passenden Insekten oder Vögel anzulocken, die ihren Pollen weitertragen, haben sie ausgefeilte Strategien entwickelt. Manche verströmen einen betörenden Duft, andere locken mit der Aussicht auf Nektar oder Sex. Für die Bestäuber jedoch endet der Blütenbesuch häufig enttäuschend.
Dracula, die "kleinen Monster" unter den Orchideen
Authors: Gerlach Günter
Published: December 2023

Bei Dracula denken die meisten vermutlich zuerst an Graf Dracula aus Siebenbürgen (Transsylvanien), den bekanntesten Vampir der Literaturgeschichte. Die Romanfigur gilt als furchterregendes, blutsaugendes Monster. Wie kommt es, dass manche Orchideen ebenfalls diesen gruseligen Namen tragen?

Organization of the rural electrification process in Ukraine during the Post-war period (second half of the 1940s – first half of the 1960s)
Authors: Korol Vitaliy
Published: December 2023

The article is devoted to the analysis of the characteristic features and peculiarities of the organization and implementation of rural electrification in Ukraine during the first post-war twenty years (1945-1965).
The author considered the post-war Soviet government regulations on the development of rural electrification. The authorities envisioned the use of electricity primarily in production processes, betting on the use of renewable energy sources and/or local, cheap fuels. This process took place under the conditions of the administrative-command system, it was authorized and directed centrally, in a directive way at the highest state level.
Three periods of implementation of this process are defined:
- the second half of the 1940s – the beginning of post-war electrification in combination with the reconstruction of the most necessary production and infrastructure facilities;
- the 1950s – active construction of autonomous power plants and creation of local power grids in rural areas;
- the first half of the 1960s – complete electrification of villages with centralized connection to a single state power grid.
The supply of equipment, installation, repair, supervision, and maintenance of rural power plants was carried out by the regional offices of the Republican Test (later the Main Directorate) of Rural Electrification ("Ukrsilelektro"/"Ukrgolovsilelektro"). However, its effectiveness remained quite low, and the quality of the work performed caused numerous complaints.
Electrification cost considerable money, took place unevenly, and depended on many local conditions (the presence of nearby rivers, fuel deposits, industrial facilities, transport connections, etc.).
The research is based on materials from the funds of the Central State Archives of Supreme Bodies of Power and Government of Ukraine and the Central State Archives of Public Associations and Ukrainians.

Cement Polymer Mixtures are made of Cement, sand, or bulk polymers are made using polymers added to improve their compressive strength, fatigue resistance, impact, and durability. Hydraulic cement polymer composites, created with modern polymer technology, are well-known for enhancing the development of composite materials and new products. This technology aims to improve both polymer cement for new construction and its use in repairing old cement. The adhesive properties of polymer cement allow for correction and bonding of both polymer-based and conventional cement. Cement-based composite materials, such as hardened cement paste, are formed by the combination of cement, water hydration, various minerals, metals, and polymeric materials. Different combinations of these materials can result in cement binders that are used for construction. Cement, a chemical substance used as a binder, sets and hardens to bind things together. It is rarely used alone and is typically combined with sand and gravel. Polymer cement is a type of cement-polymer composite where conventional cement hydrates are replaced by polymer binders or liquid resins. It is prepared by completely replacing the hydrate binders of cement with the polymer binders or liquid resins. This mixture forms a cement-polymer composite. Cement-polymer composites are durable materials that exhibit long service life and can withstand harsh environmental conditions. They are not affected by extreme temperatures, whether hot or cold, as dry concrete has a low coefficient of expansion and can accommodate moderate movements in the design. Evaluation parameters for cement include calcium oxide, magnesium oxide, silicon dioxide, aluminum oxide, sodium oxide, potassium oxide, and sulfur trioxide.

The paper examines the Qatari institution of BeIN sports sportscasting under the guise of sports entertainment with a focus on football as the most popular sport broadcasted. In fact, the institutions exposure insidiously influences its sportscasters fans and viewers across North Africa and the Middle East in particular. This impact has manifested in the course of the World Cup Qatar 2022 tournaments. To this end, the study instrumentalizes discourse analysis and critical discourse analysis to sift the language of Arab popular sportscasters of the televised channels broadcasting international football matches including Morocco as a participative and competing team. Remarkably, the countless repetitions of Arab and Arabic-related issues cause an uproar and theft of sport enjoyment among viewers. Sport enjoyment is relegated to government politics. Accordingly, the Qatari-based media control and filters reveal that pan-Arabism and Islamism are commercialised to manufacture consensus of BeIN sports visibility and transparency. Therefore, the study concludes that these Qatari media filters strangle their channel audiences in North Africa through pan-Arabist sports commentators in particular and other continents diaspora in the main.
