(Aus-)Handlungen des Transnationalen
Authors: Keßler Catharina I. , Szakács-Behling Simona
Published: October 2023

Der Beitrag rückt Schulwebsites und diskursive Praktiken im Horizont von Transnationalisierung in den Fokus und untersucht, wie sich Transnationalisierung in den Onlinedarstellungen von Schul- und Schüler*innenaustauschen, (extra-)curricularen Angeboten und Projekten, aber auch Bezugnahmen auf die eigene Schüler*innenschaft zeigt bzw. wechselseitig hergestellt wird. Die Autorinnen verstehen Schulen in diesem Kontext als organisationale Akteurinnen und fragen nach ihrer Rolle bei Transnationalisierung als einem zunehmend bildungspolitisch wie wissenschaftlich relevanten Phänomen sowie nach Ambivalenzen und Ambiguitäten schulischer Transnationalisierung, wie sie in diskursiven (Aus-)Handlungen auf Schulwebsites hinsichtlich ungleicher Vorstellungen von Vielfalt und Teilhabe gezeigt werden können.

Leucine-rich glioma inactivated 1 (LGI1) is a glycoprotein secreted by neurons, the deletion of which leads to autosomal dominant lateral temporal lobe epilepsy. We previously showed that LGI1 deficiency in a mouse model (i.e., knock-out for LGI1 or KO-Lgi1) decreased Kv1.1 channel density at the axon initial segment (AIS) and at presynaptic terminals, thus enhancing both intrinsic excitability and glutamate release. However, it is not known whether normal excitability can be restored in epileptic neurons. Here, we show that the selective expression of LGI1 in KO-Lgi1 neurons from mice of both sexes, using single-cell electroporation, reduces intrinsic excitability and restores both the Kv1.1-mediated D-type current and Kv1.1 channels at the AIS. In addition, we show that the homeostatic-like shortening of the AIS length observed in KO-Lgi1 neurons is prevented in neurons electroporated with the Lgi1 gene. Furthermore, we reveal a spatial gradient of intrinsic excitability that is centered on the electroporated neuron. We conclude that expression of LGI1 restores normal excitability through functional Kv1 channels at the AIS.

SIGNIFICANCE STATEMENTThe lack of leucine-rich glioma inactivated 1 (LGI1) protein induces severe epileptic seizures that leads to death. Enhanced intrinsic and synaptic excitation in KO-Lgi1 mice is because of the decrease in Kv1.1 channels in CA3 neurons. However, the conditions to restore normal excitability profile in epileptic neurons remain to be defined. We show here that the expression of LGI1 in KO-Lgi1 neurons in single neurons reduces intrinsic excitability, and restores both the Kv1.1-mediated D-type current and Kv1.1 channels at the axon initial segment (AIS). Furthermore, the homeostatic shortening of the AIS length observed in KO-Lgi1 neurons is prevented in neurons in which the Lgi1 gene has been rescued. We conclude that LGI1 constitutes a critical factor to restore normal excitability in epileptic neurons.
Predicting Atrophy of the Cochlear Stria Vascularis from the Shape of the Threshold Audiogram

Published: October 2023

Several lines of evidence have suggested that steeply sloping audiometric losses are caused by hair cell degeneration, while flat audiometric losses are caused by strial atrophy, but this concept has never been rigorously tested in human specimens. Here, we systematically compare audiograms and cochlear histopathology in 160 human cases from the archival collection of celloidin-embedded temporal bones at the Massachusetts Eye and Ear. The dataset included 106 cases from a prior study of normal-aging ears, and an additional 54 cases selected by combing the database for flat audiograms. Audiogram shapes were classified algorithmically into five groups according to the relation between flatness (i.e., SD of hearing levels across all frequencies) and low-frequency pure-tone average (i.e., mean at 0.25, 0.5, and 1.0 kHz). Outer and inner hair cell losses, neural degeneration, and strial atrophy were all quantified as a function of cochlear location in each case. Results showed that strial atrophy was worse in the apical than the basal half of the cochlea and was worse in females than in males. The degree of strial atrophy was uncorrelated with audiogram flatness. Apical atrophy was correlated with low-frequency thresholds and basal atrophy with high-frequency thresholds, and the former correlation was higher. However, a multivariable regression with all histopathological measures as predictors and audiometric thresholds as the outcome showed that strial atrophy was a significant predictor of threshold shift only in the low-frequency region, and, even there, the contribution of outer hair cell damage was larger.

SIGNIFICANCE STATEMENTCochlear pathology can only be assessed postmortem; thus, human cochlear histopathology is critical to our understanding of the mechanisms of hearing loss. Dogma holds that relative damage to sensory cells, which transduce mechanical vibration into electrical signals, versus the stria vascularis, the cellular battery that powers transduction, can be inferred by the shape of the audiogram, that is, down-sloping (hair cell damage) versus flat (strial atrophy). Here we quantified hair cell and strial atrophy in 160 human specimens to show that it is the degree of low-frequency hearing loss, rather than the audiogram slope, that predicts strial atrophy. Results are critical to the design of clinical trials for hearing-loss therapeutics, as current drugs target only hair cell, not strial, regeneration.
IMPLICATIONS OF STABILIZERS USED IN BRINE OF SOFT WHITE CHEESE ON THE AROMA PROFILE OF CHEESES
Authors: ÖZBEK Çağla , GÜZELER Nuray
Published: October 2023

This paper describes the compositional characterization of cheese brine and aroma profile of Soft White cheese which contains different stabilizers such as sodium caseinate, carrageenan and guar gum in the brine solutions. During the 60-day storage period, pH, titration acidity, dry matter, fat, salt and protein amounts of cheese brines were analyzed. The aroma profile of the cheese samples was examined by gas chromatography–mass spectrometry using a solid-phase microextraction technique and the proportional distribution of volatile compounds was revealed. The stabilizers in the brine increased the dry matter content in the cheese mass by binding the water and reduced salt penetration into the cheese mass. A total of 23 aromatic compounds were identified including 4 aldehydes, 5 alcohols, 4 esters, 1 ether, 5 hydrocarbons, 2 ketones and 2 organic acids in cheeses. Carrageenan and guar gum were found more effective than sodium caseinate in terms of flavor retention.

The mechanisms utilized by different flaviviruses to evade antiviral functions of interferons are varied and incompletely understood. Using virological approaches, biochemical assays, and mass spectrometry analyses, we report here that the NS5 protein of tick‐borne encephalitis virus (TBEV) and Louping Ill virus (LIV), two related tick‐borne flaviviruses, antagonize JAK–STAT signaling through interactions with the tyrosine kinase 2 (TYK2). Co‐immunoprecipitation (co‐IP) experiments, yeast gap‐repair assays, computational protein–protein docking and functional studies identify a stretch of 10 residues of the RNA dependent RNA polymerase domain of tick‐borne flavivirus NS5, but not mosquito‐borne NS5, that is critical for interactions with the TYK2 kinase domain. Additional co‐IP assays performed with several TYK2 orthologs reveal that the interaction is conserved across mammalian species. In vitro kinase assays show that TBEV and LIV NS5 reduce the catalytic activity of TYK2. Our results thus illustrate a novel mechanism by which viruses suppress the interferon response.

Local self-government is an important component of the democratic system in Ukraine, and Odesa and the Odesa region are no exception. This article examines the peculiarities of local self-government in Odesa and the Odesa region. One of the peculiarities of local self-government in Odesa and the Odesa region is the presence of many local initiatives and community organizations that actively participate in their territories’ development. This allows for more resources and ideas to be mobilized to address the problems faced by the city and region. If local self-government is successfully implemented in Odesa and the Odesa region, it could serve as an example for other regions in Ukraine. However, in order to achieve success, it is necessary to ensure the effective functioning of local government bodies, to increase the level of citizens’ participation in the decentralization process, reform local self-government, define the powers of local authorities, establish the local self-government budget, and conduct local elections.

We show that this problem is equivalent to one when you want to find out the symmetric random walk with bounded length of steps which maximizes the probability to visit an interval [x;∞]. The function x \mapsto Dn(x) allows a simple description and is closely related to the binomial tail probabilities. We can interpret the result as a final and optimal upper bound ℙ{Mn ≥ x} ≤ Dn(x), x ∈ ℝ, for the tail probability ℙ {Mn ≥ x}.

Heat stress in cattle results from the combination of several weather variables such as ambient temperature, relative humidity, solar radiation and wind speed. These factors can have a negative impact on both animal welfare and performance.
It is known that the majority of cattle farming sites are located near or outside settlements. It is for this reason that the object of this paper is a concept for the implementation of an IoT-based metrology station, through which real time information on measured atmospheric parameters can be obtained, thereby counteracting the possible occurrence of heat stress in animals.
Negotiating Ecological Relations Amongst Inclusive Heathens
Authors: Davy Barbara Jane
Published: October 2023

An investigation of Winterfinding, a harvest feast, as conducted by Vindisir Kindred, a small group of contemporary Heathens in southwestern Ontario, shows how the development of ecological conscience is involved in ritual practices that negotiate meaning and environmental values. Ritual practices such as this that include animal sacrifice can embody an ecological conscience through physical practices that embed tacit learning of how to relate with others, human and otherwise. Ritual feasting and practices of making offerings in this community of contemporary Heathens is in the process of negotiating ecological relations. Participating in such practices can contribute to the formation a pro-environmental disposition and orientation, although what this means for participants continues to evolve.
‘There’s Divinity in Everything Here’

Published: October 2023

Contemporary Pagan nature sanctuaries across the United States feature practices such as ecosystem restoration, species preservation, and green burial. Pagans ritualize these practices in ways that both express and constitute reverential or intimate relations between humans, soil, plants, rocks, nonhuman animals, and spiritual beings. Their nature sanctuaries also express particular relationships with the more-than-human world through creating various kinds of sacred spaces, including shrines and altars. Because they are separated from most visitors’ daily lives, these sanctuaries work for many visitors as portals to a different state of consciousness in which human and nonhuman nature are experienced in powerful ways. This paper will explore the ritualized ways that environmentally conscious practices are promoted and engaged with at these sanctuaries. I will focus particularly on two sets of tensions: 1) leaving spaces wild and domesticating them and 2) natural burial and ecosystem restoration that brings species back to life. These varied practices reveal different ways of understanding ‘nature’ and ‘the wild’.

IMPROVED MULTI-OBJECTIVE OPTIMIZATION IN BUSINESS PROCESS MANAGEMENT USING R-NSGA-II
Authors: Filatov V. O. , Yerokhin M. A.
Published: October 2023

Context. Business process management is a critical component in contemporary organizations for maintaining efficiency and achieving operational objectives. Optimization of these processes in terms of time and cost can lead to significant improvements in overall business performance. However, traditional optimization techniques often face challenges in handling multi-objective problems with a known time-cost trade-off, necessitating more effective solutions. The integration of a business process model and notation for a stochastic process simulation provides a robust foundation for analyzing these business processes and complies with stateof-the-art business process management. In prior studies, we applied several heuristic algorithms, including the evolutionary NSGAII, to find a Pareto-optimal set of solutions. We defined a solution as a pair of cost and time associated with a specific resource allocation. For one of the selected processes, the performance of NSGA-II was subpar compared to other techniques.

Objective. The goal of this study is to improve upon the NSGA-II’s performance and, in turn, enhance the efficiency of multiobjective business process optimization. Specifically, we aim to incorporate reference points into NSGA-II. Our goal is to identify an optimized set of solutions that represent a trade-off between process execution time and the associated cost. We expect this set to have a higher spread and other quality metrics, compared to the prior outputs.

Method. To accomplish our objective, we adopted a two-step approach. Firstly, we modified the original genetic algorithm by selecting and integrating the reference points that served to guide the search towards the Pareto-optimal front. This integration was designed to enhance the exploration and exploitation capabilities of the algorithm. Secondly, we employed the improved algorithm, namely R-NSGA-II, in the stochastic simulations of the business processes. The BPMN provided the input for these simulations, wherein we altered the resource allocation to observe the impact on process time and cost.

Results. Our experimental results demonstrated that the R-NSGA-II significantly outperformed the original NSGA-II algorithm for the given process model, derived from the event log. The modified algorithm was able to identify a wider and more diverse Pareto-optimal front, thus providing a more comprehensive set of optimal solutions concerning cost and time.

Conclusions. The study confirmed and underscored the potential of integrating the reference points into NSGA-II for optimizing business processes. The improved performance of R-NSGA-II, evident from the better Pareto-optimal front it identified, highlights its efficacy in multi-objective optimization problems, as well as the simplicity of the reference-based approaches in the scope of BPM. Our research poses the direction for the further exploration of the heuristics to improve the outcomes of the optimization techniques or their execution performance.
GENERALIZED FRACTIONAL GAUSSIAN NOISE PREDICTION BASED ON THE WALSH FUNCTIONS
Authors: Gorev V. N. , Gusev A. Yu. , Korniienko V. I. , Shedlovska Y. I.
Published: October 2023

Context. Some of the authors’ recent papers were devoted to the Kolmogorov-Wiener filter for telecommunication traffic prediction in some stationary models, such as the fractional Gaussian noise model, the power-law structure function model, and the GFSD (Gaussian fractional sum-difference) model. Recently, the so-called generalized fractional Gaussian noise model was proposed for stationary telecommunication traffic description in some cases. So, in this paper the theoretical fundamentals of the continuous Kolmogorov-Wiener filter used for the prediction of the generalized fractional Gaussian noise are investigated.

 Objective. The aim of the work is to obtain the filter weight function as an approximate solution of the corresponding Wiener– Hopf integral equation with the kernel equal to the generalized fractional Gaussian noise correlation function.

Method. A truncated Walsh function expansion is proposed in order to obtain the corresponding solution. This expansion is a special case of the Galerkin method, in the framework of which the unknown function is sought as a truncated series in orthogonal functions. The integral brackets and the results for the mean absolute percentage errors, which are a measure of discrepancy between the left-hand side and the right-hand side of the Wiener-Hopf integral equation, are calculated numerically on the basis of the Wolfram Mathematica package.

Results. The investigation is made for approximations up to sixty four Walsh functions. Different model parameters are investigated. It is shown that for different model parameters the proposed method is convergent and leads to small mean absolute percentage errors for approximations of rather large numbers of Walsh functions.

Conclusions. The paper is devoted to a theoretical construction of the continuous Kolmogorov-Wiener filter weight function for the prediction of a stationary random process described by the generalized fractional Gaussian noise model. As is known, this model may give a good description of some actual telecommunication traffic data in systems with packet data transfer. The corresponding weight function is sought on the basis of the truncated Walsh function expansion method. The corresponding discrepancy errors are small and the method is convergent.
K-NN’S NEAREST NEIGHBORS METHOD FOR CLASSIFYING TEXT DOCUMENTS BY THEIR TOPICS
Authors: Boyko N. I. , Mykhailyshyn V. Yu.
Published: October 2023

Context. Optimization of the method of nearest neighbors k-NN for the classification of text documents by their topics and experimentally solving the problem based on the method.

Objective. The study aims to study the method of nearest neighbors k-NN for classifying text documents by their topics. The task of the study is to classify text documents by their topics based on a dataset for the optimal time and with high accuracy.

Method. The k-nearest neighbors (k-NN) method is a metric algorithm for automatic object classification or regression. The k-NN algorithm stores all existing data and categorizes the new point based on the distance between the new point and all points in the training set. For this, a certain distance metric, such as Euclidean distance, is used. In the learning process, k-NN stores all the data from the training set, so it belongs to the “lazy” algorithms since learning takes place at the time of classification. The algorithm makes no assumptions about the distribution of data and it is nonparametric. The task of the k-NN algorithm is to assign a certain category to the test document x based on the categories k of the nearest neighbors from the training dataset. The similarity between the test document x and each of the closest neighbors is scored by the category to which the neighbor belongs. If several of k’s closest neighbors belong to the same category, then the similarity score of that category for the test document x is calculated as the sum of the category scores for each of these closest neighbors. After that, the categories are ranked by score, and the test document is assigned to the category with the highest score.

Results. The k-NN method for classifying text documents has been successfully implemented. Experiments have been conducted with various methods that affect the efficiency of k-NN, such as the choice of algorithm and metrics. The results of the experiments showed that the use of certain methods can improve the accuracy of classification and the efficiency of the model.

Conclusions. Displaying the results on different metrics and algorithms showed that choosing a particular algorithm and metric can have a significant impact on the accuracy of predictions. The application of the ball tree algorithm, as well as the use of different metrics, such as Manhattan or Euclidean distance, can lead to improved results. Using clustering before applying k-NN has been shown to have a positive effect on results and allows for better grouping of data and reduces the impact of noise or misclassified points, which leads to improved accuracy and class distribution.
