Functional connectivity and temporal dynamics of EEG in novice meditators: Association of psychomotor vigilance test performance changes and mean phase coherence
Authors: Guerriero Ren , Dundon Stephen , Joshi Shreyas , Stromberg Arnold , Sunderam Sridhar , O'Hara Bruce
Published: October 2023

Background Coherence analysis examines the functional connectivity of
cortical regions, which are important for cognitive functioning and may
be related to the benefits of meditation. Meditation analysis to date
has analyzed coherence by comparing EEG wave power using Fast Fourier
Transform (FFT), and then calculating the coherence spectra with
disregard to wave phase. This method can show spurious coherence between
regions that are unlikely to be synchronized. Our methods used a phase
synchronization measure of coherence, mean phase coherence (MPC) - novel
to meditation. Methods Attentional performance before and after
20-minute eye-closed focused attention meditation was measured in 25
healthy, meditation naïve subjects. MPC was calculated in wave specific
bins and for every 30 seconds during meditation. To determine if these
EEG hallmarks showed relation with performance changes, MPC and power
was then correlated to PVT results. Results MPC showed high alpha
coherence between front-temporal and frontal-occipital electrodes.
Meditation also underwent temporal changes with high prefrontal gamma
coherence correlated with better performance at meditation onset, with
frontal alpha and beta power later in the meditation. Alpha coherence
throughout the meditation was correlated with better attentional
performance changes. Conclusions Our data suggest that MPC may have
identified regions of high coherence during meditation that are
correlated with improved PVT performance. The results also suggest that
meditation is a dynamic neural process that requires more careful
analysis into temporal changes. Finally, results suggest that
“control” conditions need to be more systematically studied, as many
conditions may show similar neural dynamics to meditation

Authors: Shen Yuqian , Xiao Yi , Meng Chen , Ouyang Zhiyun
Published: October 2023

We aimed to evaluate the supply capacity and use status of the ecosystem
in Miyun County. The potential and actual gross ecosystem products
(GEPs), describing the background condition of an ecosystem and human
demand for ecosystem products, respectively, were estimated. In 2020,
the actual GEP of Miyun County accounted for 21% of the potential GEP.
Water retention and climate regulation services were the highest in the
potential and actual GEPs, respectively. The contributions of wetlands
and forests were the highest in the potential and actual GEPs. Natural
ecosystem area and vegetation coverage were the main factors affecting
the potential GEP, whereas the actual GEP was mainly affected by gross
domestic product (GDP) and population. Using Miyun County data, we
quantitatively analysed the supply capacity and actual use of ecosystem
products to clarify the interdependence between the ecosystem and human
society to support decisions for regional eco-sustainability.

Passivating contact solar cells have gradually become the mainstream
cell technology due to their excellent performance, and further
improving the conversion efficiency has become a focus of subsequent
research. Typically, achieving excellent field-effect passivation and
low contact resistivity in doped polycrystalline silicon (poly-Si) solar
cells requires heavy phosphorus doping. However, this approach can lead
to a predicament where excessive phosphorus diffuses into the Si
substrate during annealing, causing recombination losses. To address
this challenge, a tandem passivation contact structure incorporating an
intrinsic amorphous silicon (a-Si ( i)) film within the
passivation layers is introduced to retard the diffusion of phosphorus
into the Si substrate. Comprehensive characterizations of the tandem
structure were carried out to delve into the underlying mechanisms of
films with the integrated a-Si ( i) layer, including simulations,
surface microscopy, active dopants profiling, crystallographic
structure, chemical bonding, elemental distribution, and electrical
properties. Simulations revealed that the inserted intrinsic layer
effectively counteracts the clustering of phosphorus atoms, leading to a
more even distribution during crystal growth. Furthermore, active dopant
profiles indicate the potential of the introduced a-Si ( i) layer
to tailor the in-diffused dopant profile. Microscopy investigations
revealed the occurrence of blistering when the a-Si ( i)
thickness exceeds 30 nm. Passivation and contact performances of TOPCon
solar cells were assessed as the a-Si ( i) thickness was varied.
Notably, optimal electrical properties were achieved with 20 nm a-Si (
i) thickness. At this thickness, the implied open-circuit voltage
( iV) of the hydrogenated lifetime sample was
promoted to more than 736.6 mV on the polished wafer, corresponding to
the lowest single-side saturation current density ( J) of 4.3 fA/cm . In addition, a low
contact resistivity of 1.4 mΩ·cm was achieved. Based
on this tandem passivation contact structure, industrial-sized TOPCon
solar cells were fabricated, giving an average efficiency of 23.83%,
0.25% higher than that of the baseline counterparts on the production
line. The above results demonstrate the role of the a-Si ( i)
film as a buffer layer, retarding the diffusion of phosphorus into the
Si substrate and obtaining a better passivation effect. This enables us
to further tailor the doping profile for high-efficiency solar cells.
Our work thus highlights a promising strategy to improve the performance
of TOPCon solar cells and showcases its potential for implementation in
industrial manufacturing.

Streambed grain sizes and hydro-biogeochemistry (HBGC) control river
functions. However, measuring their quantities, distributions, and
uncertainties is challenging due to the diversity and heterogeneity of
natural streams. This work presents a photo-driven, artificial
intelligence (AI)-enabled, and theory-based workflow for extracting the
quantities, distributions, and uncertainties of streambed grain sizes
and HBGC parameters from photos. Specifically, we first trained You Only
Look Once (YOLO), an object detection AI, using 11,977 grain labels from
36 photos collected from 9 different stream environments. We
demonstrated its accuracy with a coefficient of determination of 0.98, a
Nash–Sutcliffe efficiency of 0.98, and a mean absolute relative error
of 6.65% in predicting the median grain size of 20 testing photos. The
AI is then used to extract the grain size distributions and determine
their characteristic grain sizes, including the 5th, 50th, and 84th
percentiles, for 1,999 photos taken at 66 sites. With these percentiles,
the quantities, distributions, and uncertainties of HBGC parameters are
further derived using existing empirical formulas and our new
uncertainty equations. From the data, the median grain size and HBGC
parameters, including Manning’s coefficient, Darcy-Weisbach friction
factor, interstitial velocity magnitude, and nitrate uptake velocity,
are found to follow log-normal, normal, positively skewed, near
log-normal, and negatively skewed distributions, respectively. Their
most likely values are 6.63 cm, 0.0339 s·m-1/3, 0.18, 0.07 m/day, and
1.2 m/day, respectively. While their average uncertainty is 7.33%,
1.85%, 15.65%, 24.06%, and 13.88%, respectively. Major uncertainty
sources in grain sizes and their subsequent impact on HBGC are further
studied.
Impact of surface turbulent fluxes on the formation of convective rolls in a Mediterranean windstorm
Authors: Lfarh Wahiba , Pantillon Florian , Chaboureau Jean-Pierre
Published: October 2023

Convective rolls contribute largely to the exchange of momentum,
sensible heat and moisture in the boundary layer. They have been shown
to reinforce air-sea interaction under strong wind conditions. This
raises the question of how surface turbulent fluxes can, in turn, affect
the rolls. Representing the air-sea exchanges during extreme wind
conditions is a major challenge in weather prediction and can lead to
large uncertainties in surface wind speed. The sensitivity of rolls to
different representations of surface fluxes is investigated using Large
Eddy Simulations. The study focuses on the Mediterranean windstorm
Adrian, where convective rolls resulting from thermal and dynamical
instabilities are responsible for the transport of strong winds to the
surface. Considering sea spray in the parameterization of surface fluxes
significantly influences roll morphology. Sea spray increases heat
fluxes and favors convection. With this more pronounced thermal
instability, the rolls are 30\% narrower and extend over
a greater height, and the downward transport of momentum is intensified
by 40\%, resulting in higher wind speeds at the surface.
Convective rolls vanish within a few minutes in the absence of momentum
fluxes, which maintain the wind shear necessary for their organization.
They also quickly weaken without sensible heat fluxes, which feed the
thermal instability required for their development, while latent heat
fluxes play minor role. These findings emphasize the necessity of
precisely representing the processes occurring at the air-sea interface,
as they not only affect the thermodynamic surface conditions but also
the vertical transport of momentum within the windstorm.

Domestic Support of Livestock Production in Ukraine
Authors: Dibrova Anatolii , Dibrova Larysa , Krylov Yaroslav
Published: October 2023

Livestock plays an important role in food supplying. However, this industry is today in Ukraine in a difficult situation. A gradual reduction of livestock numbers affected both the output and the changes in the structure and range of livestock production. In recent years, there has been a tendency to a reduction of meat and milk consumption in the Ukraine’s domestic market due to the low purchasing power of individuals, which therefore causes difficulties for the country’s food security. In the structure of livestock production in Ukraine, the dominant place belongs to farms. However, small-scale production is not able to provide high quality products and volumes necessary to meet domestic demand. With significant available resources of Ukraine, the country instead of exporting the livestock products has become an importer. The Ukrainian allocations to supporting the livestock production are quite significant, due to budgetary payments and subsidies or rebates in the value added tax (VAT). However, this does not significantly influence either the output or the performance indicators of improvement in the livestock production. All this testifies to the imperfection of mechanism of state support for the livestock production in Ukraine. The global financial crisis has reduced the financial capacity of the state support for the livestock industry. Therefore, under these conditions, there is an urgent need of an efficient use of budgetary resources and of an improvement of the mechanism of support for the livestock production in Ukraine.

The evolution of the agricultural protectionism and its measures
Authors: Pawlak Karolina
Published: October 2023

The aim of the article was to present the premises and evolution of protectionism in agricultural trade and to show the changes in significance of tariff and non-tariff barriers of intervention for the trade in agricultural products. The abolition of customs duties entails an increase in the number and the role of non-tariff barriers in trade policy applied by individual countries. The factors determining the degree of intensity in the use of protective instruments include the level of GDP per capita. In the agri-food sector, an intensified protectionism can be observed along with an increased degree of economic development. In spite of the fact that richer countries declare their support for free trade, they take intense actions to protect their domestic production from the competitive imports and are unwilling to abandon this policy, which can be observed e.g. in prolonged negotiations on further liberalisation of world agricultural trade in the WTO forum.

Properties of operator constitutive relations in mechanics of deformable solid
Authors: Georgievskii Dimitri
Published: October 2023

The constitutive relations between stresses and strains in the mechanics of a deformable solid, including their operator connection, are considered. Some important and frequently occurring properties of tangent modulus and tangent pliability as rank four tensors are described. Depending on this, a possible classification of continuous media is proposed. Scleronomous and rheonomic media, homogeneous and inhomogeneous media (in particular, composites), media with memory, spatially nonlocal media, materials with hard or soft characteristics are distinguished. For non-linearly elastic isotropic media, the apparatus of tensor nonlinear isotropic functions of one argument is developed. Particular attention is paid to the three-term representation of power tensor series in three-dimensional space, reversibility of tensor functions, Taylor tensor series, tensor linearity (quasilinearity) and nonlinearity.

Employment Advocate vs Employment Lawyer: A comparative analysis between New Zealand, Australia, and the United Kingdom
Authors: Dimitrov Dara
Published: October 2023

New Zealand is facing a burgeoning number of employment advocates in its legal system, especially since the Covid-19 pandemic. As part of the enactment of the Employment Relations Act (ERA) 2000, New Zealand’s parliament intended that employment disputes be resolved in a non-adversarial and efficient manner that required little legal representation. Employment advocates are meant to meet that need; a relatable agent for an employment litigant that resolves disputes faster and cheaper. However, there have been increasing concerns from the employment judges, the New Zealand Law Society, lawyers and the public about the professionalism and competency of employment advocates. Recent case law questions whether employment advocates can continue to operate without restrictions or an oversight body. This paper demonstrates why some employment advocates operate below the standards expected by the courts and the impact it has on their employment litigants or clients. An international comparison to paid agents in Australia and McKenzie friends in the United Kingdom is also included. This paper recommends that the current operations of employment advocates undermine employment litigants’ access to justice and that New Zealand’s parliament needs to reconsider the role of employment advocates in employment disputes.
Structural Changes in the Royal Navy and the Rotation of the British Naval Elite during the First World War
Authors:   Bryansk State University named after academician I.G. Petrovsky, Shendygaev Dmitriy I.
Published: October 2023

Great Britain, due to geographical location and the need to maintain dominance on the seas, emphasized the actions of its Royal Navy during military conflicts. The realities of World War I forced Great Britain’s military and political leadership to reconsider the country's traditional role in international military conflicts. A pressing issue facing the military and political elite was the development of military plans aimed at harnessing Great Britain’s Naval Forces. Proposed drafts by British Admiralty representatives such as J. Fisher, W. Churchill, and J. Jellico often met with obstruction from the state's political leaders and the Army elite. On the eve of the war and during the hostilities, representatives of the elite proposed various plans for the use of the country’s Royal Navy, the implementation of which led both to the fleet's structural changes and to the rotation of the military elite.
Status and Features of Dialogue in Art
Authors:   Astrakhan State University named after V.N. Tatishchev, Kucheruk Irina V.
Published: October 2023

The article focuses on the types and features of dialogue in art, based on the exteriorized and interiorized inter-action of its subjects. Based on the research of dialogists, the author of the article hinges primarily on a broad interpretation of dialog as a form of being in culture, a form of communication between cultures, taking into account the form of understanding culture. The essence of this joint existence or co-existence is the interaction of its participants, expressed in replicas, including “reciprocal equal word”. Particular attention is paid to interior-ized (“unarticulated”, “monologic”) dialogue, which is more difficult to instrumentalize. It is subdivided by the author into the dialog of the creator-creator, creator-customer, creator-viewer. Under the influence of this “multi-place” and diverse dialogue, as emphasized in the article, there is not only a transformation of the inner world of its subjects, but also the formation of a cultural tradition.
Fear and Anxiety: Philosophical Problems of Human Existence
Authors:   Kuban State Technological University, Kuzemina Elena F. , Kosivchenko Ekaterina V. ,   Kuban State Technological University
Published: October 2023

The article examines the representations of fear in the history of philosophy, along with their anthropological and ontological basis. The essential component of philosophical theories, according to the authors, is the anal-ysis of social aspects of fear and anxiety as elements of social behavior. The subject of research in this article is the phenomenon of fear as a problem of human existence. Despite numerous works devoted to the historical and philosophical analysis of ideas about fear, the understanding of this phenomenon remains relevant in the modern world. The era of permocrisis, characterized by instability and insecurity, generates new forms of fear and encourages people to rethink the foundations of their existence, to reflect on the meaning of life and search for answers to worldview questions. The aim of the article is a philosophical analysis that allows to comprehend this phenomenon and its modus operandi, such as horror, anxiety, panic in the modern world. Using elements of historical and philo-sophical analysis of representations about fear, the authors point to the formed theoretical and methodological basis of modern research in this field. According to the authors, the socio-philosophical analysis reveals new opportunities for understanding the phenomenon of fear, revealing its positive potential. Salvation from fear in its positive comprehension - as part of the existential-philosophical picture of the world. Awareness of one’s own fear is able to provide a person with a central motivational force, to induce a search for the meaning of life and belief in the limitlessness of one's own power.

Assessing the role of institutional reform in enhancing Balkan sustainable competitiveness: An Entropy-MARCOS perspective
Authors: Štilić Anđelka , Puška Adis , Božanić Darko , Tešić Duško
Published: October 2023

This research paper aims to assess the sustainable competitiveness of Balkan countries. Sustainable competitiveness was measured based on the indicators in The Sustainable Competitiveness Report from 2022, published by Solability. According to this report, sustainable competitiveness is evaluated using six grouped criteria. In this paper, the competitiveness of the Balkan countries was assessed through the application of the multicriteria analysis methods Entropy and MARCOS (Measurement Alternatives and Ranking according to the Compromise Solution). The weight of each criterion was determined using the Entropy method. The results highlighted that the most significant criteria were Natural Capital and Resource Efficiency & Intensity, which carried the highest weight, whereas the Social Cohesion criterion was of lesser importance, represented by the lowest weight. Using the MARCOS method, the Balkan countries were ranked, with Greece securing the top position, closely followed by Albania, while North Macedonia exhibited the weakest performance. Sensitivity analysis further substantiated these findings. The outcomes of this study significantly contribute to the academic understanding of sustainable competitiveness and provide valuable practical insights for policymakers and stakeholders interested in advancing sustainable development efforts in the Balkan region.
Effect of Crude Oil Revenue on the Oil and Non-oil Sectors in Nigeria
Authors: Salaudeen Mohammed Bashir
Published: October 2023

The debate for oil-rich economies to plough their oil windfalls into real economic activities to spur diversification has become intense due to the deficit fiscal crisis and poor socio-economic profile of resource-abundant nations. Therefore, we use secondary data from the period between 1981 and 2020 to assess the impact of crude oil revenue on the oil and non-oil sector output performance in Nigeria. The study adopts the ARDL (i.e. autoregressive distributed lag) and the augmented Granger causality techniques to analyse the data. The ARDL regressions show that crude oil positively impacts oil sector performance, but the impact is only substantial in the short run. Crude oil revenue exerts a positive and insignificant effect on the short-run non-oil sector output, whereas, over the long run, it has a negative but significant effect. To propel growth, the study recommends using the excess crude oil earnings to develop non-oil sectors such as agriculture, services, and manufacturing.
Mathematical analysis of the Royal Game of Ur
Authors: Raposo Diego J. , Lamont Padraig X.
Published: October 2023

Despite many discoveries and proposals for rules for the ancient board game known as the Royal Game of Ur (RGU), no mathematical analysis has yet been performed investigating those rules. In an attempt to fill that gap, this paper presents an initial mathematical analysis of the RGU from an introductory point of view. The paper deduces the overall complexity of the RGU using a state-space and game-tree complexity analysis, allowing the RGU to be compared to the popular games Checkers, Backgammon, Ludo, Chess, and Go. The paper builds upon the fundamental laws of combinatorics and probability to improve the understanding of the game: what patterns should you expect, what moves increase your chance to win, and what moves should you avoid. The paper also presents theorems to predict the probability of future dice rolls and piece movements within the game, allowing basic inferences to be made about strategy in the RGU. The game is further examined by analysing three different influences when determining the best move: advancement and attack (beneficial to the player), and captures (detrimental to the player). These influences are used to deduce explicit equations for the advantage gained by playing each possible move from a position, which allows the formalization of a strategic algorithm to play the RGU.

Background: Dermatophytosis is a superficial fungal infection caused by filamentous fungi that attack the keratinized tissue of the skin, nails, and hair. The clinical manifestations of dermatophytosis, in addition to depending on the source host factors, such as age, sex, and race, are significant epidemiological factors. However, the relationship of infection susceptibility remains unclear. Purposes: This study aimed to determine the relationship between age and sex and dermatophytosis incidence in Gianyar Regency. Methods: This study was observational with a cross-sectional design using 200 samples divided into 100 dermatophytosis patients and 100 non-dermatophytosis patients. Statistical analysis of the data used was a chi-square test with 95%CI. Results: The majority of patients with dermatophyte infections were >19 years old (74%), female (57%), and tinea corporis (36%). The chi-square test showed that there was a significant relationship between age and sex with the incidence of dermatophytosis (p = 0.025; OR = 1.978; 95% CI = 1.087-3.599 and p = 0.003; OR = 2.357; 95% CI = 1.334-4.162). Conclusion: It can be concluded that older age and female tend to suffer dermatophytosis.

Objective: To conduct tests on the B4T-5.5 hp spark-ignition engines (Otto cycle) with conventional fuels (types of gasoline) and, after modification, to test with renewable fuels (Ethanol) on the dynamometer in the engineering laboratory of Branco Motores Ltda., following SAE J1995 and SAE J1940 standards. Analyze the power and torque curves for each tested fuel.
 
Theoretical framework: Utilizing the literature through research in books, dissertations, articles, and standards.
 
Method: This study involves the performance of a gasoline engine converted to ethanol (renewable fuel) through quantitative research and the evaluation of test results on the 5.5 hp single-cylinder 4-stroke spark-ignition engine (B4T model) with each proposed fuel in the research.
 
Results and Conclusion: During the analysis, the necessary values were measured to create the power and torque curves using different types of national fuels. The spark-ignition engine was connected to a dynamometer and tested with regular gasoline (Type C with 27.5% ethanol content), premium gasoline, podium® gasoline, and anhydrous ethanol 95% (the gasoline engine was modified to operate with ethanol). In the case of the renewable fuel, ethanol, the results for the spark-ignition engine (Otto cycle) showed an increase of 0.48 hp in power and 0.11 kgf.m in torque compared to gasoline. The ethanol-powered engine is a viable alternative and is considered a clean energy source when compared to traditional fuels (such as gasoline).
 
Research Implications: Issues such as sustainability, renewable energies, environmentally friendly fuels, greenhouse gas emissions, and concerns about the environment have become increasingly common and evident in the global market. This reflects a global concern for environmental preservation and the future of the planet. For academia, the constant search for new or alternative sources will always be a challenge.
 
Originality/Value: The proposal of an ethanol engine contributes to the reduction of pollutant gas emissions and environmental damage because ethanol, derived from sugarcane, absorbs carbon monoxide and carbon dioxide during the plant's development. This attenuates emissions since, during the ethanol burning process, the gases are only returned to the atmosphere (carbon and derivatives), unlike the burning of fossil fuels, which adds more gases to the atmosphere. Another point is that it provides an additional option for end consumers.

Published: October 2023

This study aims to examine the carbon substitution effect in Korea's major carbon-intensive industry, the construction industry. To accomplish this, we estimate the factor demand functions for the building construction and maintenance industry as well as the civil construction industry using the SUR model. Subsequently, we conduct a simulation analysis to assess the carbon substitution effect resulting from the replacement of wood with other factor inputs in each industry. The data utilized in this study are gathered from the Bank of Korea's Input-Output table and the Bank of Korea's producer price index. The estimated results of the factor demand functions reveal a substitutive relationship between wood and wood products with processed metal products within the construction industry. The simulation analysis indicates that an 8.75% increase in demand for wood and wood products within the construction industry can lead to the most significant reduction in total greenhouse gas (GHG) emissions for the industry, amounting to 277.52 thousand tons. This study is the first to quantify carbon substitution effects from an economic perspective, thereby contributing to providing insights for governments in formulating policies related to carbon neutrality.

¡Santa, oh Santa Evita! La mujer y el mito a través del audiovisual del siglo XXI
Authors:   Universidad de La Laguna (España), Marcos Arteaga Irene C.
Published: October 2023

Over seventy years ago, Eva Duarte was defeated by cancer, being mourned by her beloved Argentina and leaving behind her a myth that is still more alive than ever. Far from being forgotten, Evita returns repeatedly as a true contemporary icon. This paper has two objectives: first is to point out the importance of cinema and theatre as a way of spreading and creation of ideas and identities; in this case, of political hagiographies that transform their characters into icons of undoubted strength, sublimating their miseries and heroizing their triumphs. Secondly, we will unravel the key elements that were used to create the hagiography of Eva Perón, a manipulated image who ruled a country protected by her union with General Perón.
