Petrification in Contemporary Set Theory: The Multiverse and the Later Wittgenstein
Authors: Pérez-Escobar José Antonio , Rittberg Colin Jakob , Sarikaya Deniz 
Published: November 2024

Abstract
This paper has two aims. First, we argue that Wittgenstein’s notion of petrification can be used to explain phenomena in advanced mathematics, sometimes better than more popular views on mathematics, such as formalism, even though petrification usually suffers from a diet of examples of a very basic nature (in particular a focus on addition of small numbers). Second, we analyse current disagreements on the absolute undecidability of CH under the notion of petrification and hinge epistemology. We argue that in contemporary set theory the usage of construction techniques for set-theoretic models in which the Continuum Hypothesis holds and those in which it fails have petrified into the normative demand that CH remain undecidable. That is, the continuous and successful practices involving the construction of various set-theoretic models now act as a normative hinge shared among practitioners, i.e., have normative force in the discipline. However, not all hinges are universal, which is why we find disagreements in set theory. We will show that this is a refinement of, and partially conflicts with, the arguments presented by set theorist Joel David Hamkins.
Die Verbreitung antisemitischer Ressentiments unter Jugendlichen und Heranwachsenden in Deutschland: Zusammenhänge mit Migration und Religion
Authors: Fischer Jannik M. K. , Wetzels Peter 
Published: November 2024

Zusammenfassung
Es werden Ergebnisse einer von März bis Mai 2022 durchgeführten Online-Befragung einer bundesweit repräsentativen Einwohnermeldeamtsstichprobe von N = 3.270 jungen Menschen im Alter von 16 bis 21 Jahren zur Verbreitung und sozialen Verteilung klassischer Formen antisemitischer Einstellungen unter Jugendlichen und Heranwachsenden in Deutschland vorgestellt. 2.1 % der jungen Personen sind danach offen für antisemitische Ressentiments und weitere 2.0 % lassen eindeutig antisemitische Einstellungen erkennen. Damit sind die Prävalenzraten antisemitischer Einstellungen in Bezug auf die Gesamtpopulation der jungen Menschen nur etwa halb so hoch wie dies bei Erwachsenen in demselben Jahr mit den gleichen Messinstrumenten festgestellt werden konnte. Es sind allerdings erhebliche Differenzen für nach Migrationshintergrund und Religionszugehörigkeit bestimmte Teilgruppen zu erkennen. Personen mit Migrationshintergrund weisen signifikant erhöhte Raten antisemitischer Einstellungen auf. Besonders stark ausgeprägt ist das bei jungen Muslim:innen. Multivariate Analysen zeigen weiter, dass die hohe Verbreitung antisemitischer Ressentiments bei jungen Muslim:innen nicht auf deren ebenfalls nachweisbar erhöhten Belastungen durch individuelle Diskriminierungserfahrungen oder die Wahrnehmung einer kollektiven Marginalisierung ihrer Eigengruppe zurückzuführen ist. Wichtige Einflussfaktoren sind, neben geringer Bildung, vor allem eine Neigung zum Verschwörungsglauben sowie eine rigide, fundamentalistische Religionsauffassung. Eine hohe individuelle Religiosität und Gläubigkeit sind hingegen multivariat nicht bedeutsam. Auffallend ist die ganz erhebliche Überrepräsentation von Muslim:innen der ersten Migrantengeneration unter den antisemitisch eingestellten jungen Menschen. Die vorgelegten Befunde haben politische wie auch praktische Implikationen für die Antisemitismusprävention. Sie zeigen, dass die zu erreichende Zielgruppe für Antisemitismusprävention unter jungen Menschen zu erheblichen Teilen aus neu zugewanderten muslimischen Migrant:innen besteht.

Abstract

Objectives
The 13-item pain catastrophizing scale (PCS) is the most commonly used measure of pain catastrophizing. A validated Finnish version of the PCS has previously been unavailable. The objectives were to translate the original English version of the PCS into Finnish (PCS-FI), then to evaluate (i) structural validity of the PCS-FI with a confirmatory factor analysis (CFA), (ii) internal reliability with Cronbach’s alpha, Omega, and Omega hierarchical, (iii) convergent validity with measures of well-being, quality of life, sleep quality, symptoms of central sensitization, and anxiety, and (iv) known-groups validity between participants with chronic low back pain (CLBP) and pain-free controls.

Methods
The translation process was performed with established guidelines. The PCS-FI was psychometrically validated using 92 participants with CLBP and 53 pain-free controls.

Results
Structural validity with CFA supported a bifactor solution. However, low reliability was found for the three specific factors (ω
h ranging from 0.14 to 0.18) compared to the general factor (ω
h = 0.88) suggesting that only the total score should be used. Convergent validity analysis showed satisfactory correlations and medium effect sizes with the other patient-reported outcome measures. Participants with CLBP had significantly higher total PCS-FI scores than pain-free controls.

Conclusions
The PCS-FI appears to be a valid and reliable instrument for assessing pain-related catastrophizing in Finnish-speaking populations. Ethical approval for this study was obtained from the Research Ethics Committee of the Northern Savo Hospital District, identification number 2131/2022, on the 31st of January 2022.

Mainland China's 2021 restrictions on under-18s' video game time were imposed when older 2019 restrictions already applied: Omitting the historical regulatory context is misleading
Authors: Xiao Leon Y. 
Published: November 2024

AbstractInvestigating the impacts of addiction policymaking following implementation is important. Effective policies should be considered for emulation elsewhere, whilst ineffective policies should be repealed. Zhou et al. (2024) reported how Mainland Chinese under-18s responded to the 2021 restrictions on their online videogame playtime, which were intended to curb online gaming addiction. However, Zhou et al. failed to mention that Mainland China had previously tried to achieve the same regulatory aim by imposing rules in 2019 that were more lenient than the 2021 rules but nonetheless restricted under-18s' gameplay time. These 2019 restrictions were neither acknowledged as crucial background in the introduction section nor accounted for by Zhou et al. when interpreting their results, thus giving readers the incorrect impression that the 2021 rules were the first ones introduced and that under-18s' gameplay time was not restricted at all prior to 2021. Importantly, Zhou et al.’s entire sample of young people therefore consisted not merely of ‘heavy gamers’ as they euphemistically described them as, but ‘counterplayers’ who actively contravened the 2019 rules. The misleading omission of this context is a major limitation and misrepresentation. The results should be interpreted accordingly and not overgeneralised.

Published: November 2024

The object of research are models of optimal logic circuits based on universal Peirce-Webb functions. The problem solved is the efficiency of the technique for simplifying the Peirce-Webb functions. The extension of the non-standard system to the simplification of Peirce-Webb functions makes it possible to discover new rules of equivalent transformations of Boolean functions, and to complete the simplification procedure in one step. A feature of the simplification of functions in the Peirce-Webb basis by a non-standard system is fixing the digital project at the level of abstraction, followed by the application of the mechanism of logical synthesis to generate the corresponding equivalent at the level of gates of the logic circuit. The result of the transformation of the terms of the binary matrix in the end is some combinatorial system, metadata that can explain other data, for example, determine the minimum function for another logical basis.
The interpretation of the result consists in the use of combinatorial properties of binary structures of functions in the Peirce-Webb basis and binary structures of functions in the basic basis. These properties do not depend on the selected logical basis, which makes it possible to carry out equivalent transformations on binary matrices of Peirce-Webb functions according to the rules of the algebra of the main basis.
It has been experimentally confirmed that a non-standard system enables:
– to reduce the algorithmic complexity of simplifying the Peirce-Webb functions;
– to increase the performance of the simplification of Peirce-Webb functions by 200–300 %;
– to demonstrate the visibility of the process of simplifying functions.
In terms of application, the non-standard system of simplifying the Peirce-Webb functions could ensure the transfer of innovations to material production: from conducting fundamental research, expanding the capabilities of digital component design technology to organizing serial or mass production of novelties.
Construction of a ballistic model of the motion of uncontrolled cargo during its autonomous high-precision drop from a fixed-wing unmanned aerial vehicle

Published: November 2024

The object of this study is the process related to the fall of an uncontrolled cargo from a height of 400–600 meters relative to sea level in an air environment under the influence of gravity, air drag, and wind in the presence of an initial air speed of about 20 m/s. The study solves the task to build a ballistic model of the movement of an unguided cargo during autonomous high-precision dropping from an unmanned aerial vehicle of aircraft type. A system of equations was derived that explicitly describes the dependence of the cargo's travel speed and coordinates on time and takes into account the effect of gravity, air drag, and the influence of wind. The scope of application of the equations corresponds to drop heights of up to 400 m relative to the surface of the earth and the initial horizontal speed of the cargo up to 20 m/s. The resulting equations were analyzed using an example of a spherical load weighing 10 kg and the largest cross-sectional area of 7.1·10-2 m2 when it falls from heights of 200, 300, and 400 m relative to the earth's surface. In the absence of wind, the horizontal component of the load's speed at the moment of falling is ≈(13–15) m/s, and the vertical component is ≈(50–60) m/s. At the same time, the horizontal displacement of the load under the conditions of a weak crosswind can reach ≈(150–220) m. With a vertical wind speed profile, the equivalent constant wind speed can be determined, resulting in the same effect on the load as a variable speed wind. An algorithm for determining the point of unloading the cargo has been proposed. The cargo delivery error has been evaluated. The most important parameters are the flight time of the cargo and the drop height. In order to achieve a hit accuracy of ±5 m, an error in determining the time of the fall of the load is not more than ≈0.16 s, and an error in determining the height of the drop is not more than ±8 m

Published: November 2024

The object of this study is the technology of bread baking based on liquid sourdough and gluten-free flour mixture. The problem with this technology is that gluten-free raw materials do not contain gluten proteins, which ensure the elasticity and firmness of the dough and increase the porosity of the bread. To improve the structural and mechanical properties of the dough, new types of flour were introduced into the recipe compared to the analog recipe: quinoa, buckwheat, and oat. The positive effect of quinoa on dough quality has been known for a long time but the limitation in its use is the bitter taste caused by the content of saponins. A method of removing saponins using ultrasound (40 kHz, τ=20 min) has been proposed, which made it possible to remove 60 % of saponins and completely remove the bitterness of grains. At the same time, the content of proteins remained unchanged while the content of phenols decreased by only 0.1 mg GAE/g. The addition of 18 % (to the mass of the flour mixture) of quinoa flour and the reduction of the starch content in the recipe had a positive effect on the organoleptic parameters of the bread quality. The acidity of dough (4.4–5.2 °Н) and bread (0.6 °Н) decreased compared to the control sample, but it was sufficient for a normal fermentation process. Bread with quinoa flour had increased moisture (more than 66 %), which can negatively affect its stability during storage. An increase in the proportion of quinoa flour in the recipe by 5 % contributed to an increase in the porosity of the crumb by 2.1 %. The proposed technology for making gluten-free bread with Quartet quinoa flour based on liquid sourdough can be industrially implemented as it makes it possible to obtain a product with desirable consumer properties. The total duration of dough ripening was reduced by 1–1.5 hours, compared to the steam method, which increases the economic efficiency of the proposed technology.

Published: November 2024

The object of this study is models for predicting students’ success, constructed on the basis of machine learning methods. The paper reports results of research into the problem of improving their accuracy by expanding the data set for training the specified models. The most available are data on student actions, which are automatically collected by learning management systems. Entering additional information about students’ work increases time and resources but allows the improvement of the accuracy of the models. In the study, information about students’ work with video materials, particularly the number and duration of views, was entered into the original data set. To automate the collection of this data, the plugin for the Moodle system has been developed, which stores information about user’s actions with the video player and the duration of watching video materials in the database. Model training was carried out using Naive Bayes (NB), logistic regression (LR), random forest (RF), and neural networks (NN) algorithms with and without video data. For the models using video viewing data, accuracy increased by 10 %, balanced accuracy by 15 %, and overall performance, expressed as area under the curve (AUC), increased by 14 %. The highest prediction accuracy, with a difference of 1.8 %, was obtained by models built using RF algorithms – 87.1 % and NN – 85.3 %. At the same time, the accuracy of the models obtained by the NB and LR algorithms was 70.7 % and 76.5 %. The increase in accuracy for them was 2.3 % and 8.1 %, respectively. Analysis of calculations confirms the assumption that students’ work with educational video materials is correlated with their success. The results make it possible to find a reasonable compromise between model development costs and its accuracy at the stage of data preparation for model training.

Published: November 2024

The use of heat pumps makes it possible to reduce energy consumption in drying processes. This study addresses the problem of efficient use of a heat pump for drying, low-temperature processing, and storage of food products. The object of the study is a heat pump unit capable of operating under the drying mode or under the refrigeration processing and storage mode. Studies have been conducted to design an experimental unit, as well as to improve the energy efficiency of the cooling system. The unit includes a single-stage freon compressor, two air condensers, a water-cooled coil heat exchanger-precondenser, an air evaporator, a thermostatic valve, axial fans, and a unit control system. It has been experimentally established that, depending on the temperature level of condensation of the refrigerant (from +20 °C to +50 °C), the increase in specific cooling capacity with the heat exchanger-precondenser turned off is from 82 kJ/kg to 135 kJ/kg, and with it turned on – from 98 kJ/kg to 143 kJ/kg. In this case, the specific work of compression of refrigerant vapors in the compressor with the heat exchanger-precondenser switched off changes from 36 kJ/kg to 18 kJ/kg. And when it is switched on – from 32 kJ/kg to 10 kJ/kg. That is, the reduction in specific energy consumption is from 4 kJ/kg to 8 kJ/kg, which indicates the advisability of including the precondenser in the installation scheme. In the installation, refrigeration treatment and storage of the product can be carried out in the temperature range from –20 °C to +20 °C and drying – from +10 °C to +40 °C. Under such modes, it is possible to obtain high-quality products with long shelf lives. The results could be used to improve the designs and optimize the operation of heat-transfer drying units and their engineering calculations

Published: November 2024

Recently, the use of nanoparticles as photocatalysts has gained great importance. However, nanoparticles exhibit some drawbacks for this application and there is a need for new particle technologies to mitigate these drawbacks. A novel particle technology called MicNo based on ZnO has been designed and manufactured, which exhibits the advantages and properties of both micron and nano size. Although performance of MicNo-ZnO has been tested in various applications, it has not been tested as a photocatalyst in any photocatalytic degradation process. In this study, novel designed ZnO was used as a catalyst for methylene blue (MB) degradation in the presence of UV irradiation. The MicNo-ZnO particles were characterized by structural and morphological properties by XRD, BET and SEM analyses. The effects of catalyst amount, pH, temperature and initial concentration on the degradation process were investigated. In addition, a reusability study was carried out with 4 cycles under optimum conditions. The MicNo-ZnO particles showed excellent photocatalytic activity with a degradation rate of 96% for methylene blue in 180 min. The pseudo-first-order rate constant for the photocatalytic degradation of MB by MicNo-ZnO was as high as 0.0236 min−1, confirming that MicNo-ZnO particles can be effectively utilized as an alternative catalyst material.
