Published: September 2024

This research aims to determine the effect of the problem based learning (PBL) model with metacognitive approach to problem solving ability on quadrilateral at seventh grade of junior high school students. The research method used is quantitative method with an experimental design, namely a posttest control design only. This research consisted of an experimental class with treatment using PBL model with metacognitive approach and control class with treatment using PBL model without metacognitive approach. The instrument in this research uses a mathematical problem solving ability test in the form of a description test. The results of research and information processing show that learning using PBL model with metacognitive approach has an influence on students' mathematical problem solving abilities. From the results of the inferential analysis of hypothesis testing using the two-sample t test, it can be seen that Ho is rejected and H1 is accepted because it meets the test criteria for tcount > ttable, 1.882 > 1.68195. So, it can be concluded that the mathematical problem solving ability of students who are taught using PBL model with metacognitive approach are higher compared to classes without metacognitive approach.
Charakter prawny polecenia doprowadzenia skazanego w celu odbycia kary

Published: September 2024

Niniejszy artykuł przedstawia poglądy autora na charakter prawny instytucji doprowadzenia skazanego do odbycia kary pozbawienia wolności w związku z nowelizacją Kodeksu karnego wykonawczego, która weszła w życie 1 stycznia 2023 roku. Wprowadzona zmiana odmiennie uregulowała czynności doprowadzenia skazanego do odbycia orzeczonej kary. Wcześniejsze regulacje w tym zakresie nie budziły większych wątpliwości, a samo polecenie doprowadzenia skazanego do aresztu śledczego nie miało charakteru decyzji procesowych. Były to czynności techniczno-administracyjne wykonywane przez prezesa sądu (przewodniczącego wydziału, upoważnionego sędziego, a w wielu sądach przez kierownika sekcji wykonawczej albo sekcji wykonywania orzeczeń). Dokonana zmiana przepisów może prowadzić do rozbieżności w ocenie charakteru prawnego tej instytucji, który wymaga nowej interpretacji. W ocenie autora polecenie doprowadzenia ma również charakter merytoryczny i procesowy, a nie tylko administracyjny. Za taką koncepcją przemawia fakt, że z tym poleceniem wiąże się faktyczne zatrzymanie, a następnie osadzenie skazanego w areszcie śledczym czy zakładzie karnym, co związane jest z rzeczywistym pozbawieniem wolności. Występują zatem tutaj elementy czynności procesowej znacznie wykraczające poza sferę administracyjno-techniczną. Skoro występują faktyczne zatrzymanie i osadzenie, to należy umożliwić skazanemu zaskarżenie takiej decyzji, a zatem będzie to kolejna gwarancja procesowa w postępowaniu wykonawczym, jak również działanie urzeczywistniające konstytucyjne prawa jednostki, w tym skazanego. Te nowe zapatrywania co do charakteru prawnego instytucji polecenia doprowadzenia, w związku z dokonanymi w tym zakresie zmianami, prowadziłyby do ewolucji prawa karnego wykonawczego i jego unowocześnienia, ale niekoniecznie do racjonalności jego stosowania.

19. yüzyılda askerî, idarî, iktisadî alanlar yanında eğitim alanında da önemli yenilikler yapıldı. II. Mahmud döneminden itibaren başlayan eğitimde modernleşme süreci Tanzimat döneminde hızlandı. İlki 1847 yılında İstanbul’da açılan erkek rüşdiye mektepleri 1850’li yıllardan itibaren taşrada yaygınlık kazanmaya başladı. 1859 yılında İstanbul’da ilk kız rüşdiye mektebi hizmete girdi. Sıbyan mekteplerini ıslah etmeye yönelik çabalar görülmekle birlikte beklenen sonuçlar alınamadı. Maarif merkez teşkilatında da kurumsal düzenlemeler yapıldı. 1857 yılında modern mekteplerin idaresi için Maarif Nezareti kuruldu. Diğer taraftan geleneksel eğitim kurumlarını oluşturan medreseler varlığını korudu. Süreç içinde gayrimüslimler ile yabancılar da mektepler açtılar. 1 Eylül 1869 tarihinde Maarif-i Umumiye Nizamnamesi yayınlanarak modern eğitim kurumları kapsamlı şekilde düzenlendi. Kazalarda ibtidai ve rüşdiye mektepleri II. Abdülhamid döneminde yaygınlık kazandı.

Çalışmada II. Abdülhamid döneminde Aydın sancağının önemli bir kazası olan Söke’de ibtidai ve rüşdiye mekteplerinin açılış süreçleri ve kurumsal yapıları ayrıntılı olarak ele alınmıştır. Arşiv belgeleri, salnameler, gazeteler ve literatür temelinde kazadaki geleneksel ve modern eğitim kurumları birlikte ele alınmış, eğitimin kurumsal yapısı ortaya çıkarılmaya çalışılmıştır.

Modern ethno-cultural differentiation of the territory of the Altai Republic
Authors: Dirin D.A. , Shiyan P.A. , Gudkovskikh M.V.
Published: September 2024

The paper concerns the analysis of the patterns and peculiarities of the settlement of ethnic groups in the territory of the Altai Republic and identification of cultural landscapes formed by these groups. The main source of information was represented by the results of the 2021 Russian Census. The use of interviewing and literature analysis allowed the verification of some data of the Census related to the ethnic identity of the residents in the region. In particular, some inaccuracies and discrepancies in the assignment of the population to specific sub-ethnic groups of the Altaians were identified and, accordingly, improved indicators of the population count for these groups have been proposed. From the results of the study, a map of ethno-cultural differentiation of the territory of the Altai Republic has been compiled, which shows areas of settlement of main ethnic groups, as well as ethno-contacting zones. The area of settlement of the Russian population spans the low- and mid-mountain regions in the north of the Republic. Also, in Central Altai, old-believers resettling there in the 18th–19th cc. formed yet another isolated areal of Russian population. The Northern Altaians (Chelkans, Tubalars, Kumandins) live in taiga low-mountain regions of North-Eastern Altai (Turochaksky, Choysky and Mayminsky Districts). In doing so, they have mixed to a large extent with the Russian population. The Southern Altaians (Altai-Kizhi and Telengits) have the largest territory of population, living mainly in Ust’-Kansky, Ongudaysky, Ust’-Koksinsky, Shebalinsky, Chemalsky (Altai-Kizhi), Ulagansky, and Kosh-Agachsky (Telengits) Districts. Kazakhs live com-pactly in the territory of Kosh-Agachsky District, as well as have a smaller enclave in Ust’-Kansky District (the village of Turata).
Dynamics of the educational level of Udmurt women in the 1920s–1980s: main trends and results
Authors: Uvarov S.N. , Chernysheva N.V.
Published: September 2024

The paper presents the study of the educational level of Udmurt women in the 1920s–1980s. The methodol-ogy of the study is based on the theory of modernisation. The transition from the traditional society to modern is considered through the prism of the cultural changes that took place in the Soviet society, the most important component of which was the increase of the level of education within the population. The authors used general scientific methods (analysis, generalisation, description, systematisation), special-historical methods (historical-chronological, historical-genetic and historical-systematic), as well as statistical methods used in demography. As the main sources, the study employed population census materials, including those unpublished (Russian Census of 1920 and Soviet Censuses of 1926, 1939, 1959, 1970, 1979, and 1989). Some of the documents containing information about the population are introduced into scientific discourse for the first time. The authors distinguish and characterise 3 stages. In the 1920s, the most important objective was to combat illiteracy and create national schools. It is concluded that the level of education of the Udmurt population, especially Udmurt village women, was significantly lower than that in the region and in the Russian Republic in general. This tendency would mani-fest itself throughout the entire study period. In the 1930s–1950s, there was a gradual change of the objectives of educating people of particular nationalities, among other, under the influence of the wartime factors. In the 1950s–1980s, there was a gradual increase in the level of education of Udmurt women, including professional education, and dilution of ethnic and gender differences, whilst the age differences in the level of education remained.

COGNITIVE FOUNDATIONS OF THE MANIPULATIVE COMMUNICATIVE STYLE MODEL
Authors:   Tver State University, Mkrtytchian S.V. , Dzundza N.V. ,   Tver State University
Published: September 2024

This article is devoted to the manipulative communicative style modeling. The object is a manipulative speech influence; the subject matter is a manipulative communicative style. The hypothesis is based on the assumption that the manipulative communicative style depends on the cognitive parameter IMPULSIVITY/ REFLECTIVITY. In accordance with the cognitive parameter IMPULSIVITY/ REFLECTIVITY were identified two manipulative communicative styles: explicit-dominant and latent. Explicit-dominant style represents highly emotional, evaluative and aggressive influence, whereas the latent style is associated with emotional restraint and rational distortion of facts. The discursive manifestation of the manipulative styles is described with the involvement of E. Shostrom’s typology of Manipulators. The experiment aimed at verifying the hypothesis consisted of two stages. At the first stage, it determined the cognitive style of the subjects. At the second stage, the relationship between cognitive style and manipulative communicative style was established. We defined the style on the basis of the answers in the open and closed type tasks. As a result of the experiment interpretation, the hypothesis was confirmed. It has proven the possibility of developing a holistic approach to the linguistic study of manipulation as a fundamentally continuous entity based on the manipulative communicative style, which is the category of integrative type.
ON CAMEO MANIFESTATION IN AMERICAN SITUATIONAL COMEDIES AND SKETCH COMEDIES
Authors:   Novosibirsk State Technical University, Bochkarev A.I. , Makarova N.E. ,   Novosibirsk State Technical University
Published: September 2024

The article explores the manifestation of cameo in humorous discourse. A comprehensive axiological approach is employed to study this phenomenon. The data analyzed in this paper comprises recordings and scripts of more than 300 episodes of different sitcoms and 100 episodes of sketch comedy. In humorous discourse cameo can function as one of the mechanisms to obtain humor. So, the very appearance of a celebrity in an episode can evoke a humorous effect. As a mechanism to obtain humor, cameo represents an example of referential non-verbal humor. Additionally, cameo’s appearance enhances humorous potential of the situations by facilitating such essential conditions for obtaining humorous effects as suddenness, novelty and joy. The authors have identified three main types of cameos in humorous discourse: celebrities under their real names, celebrities as characters of the comedy and celebrities as their famous characters from other works. It is an allusion that is considered to be the key language humor mechanism when cameos are performing, while it can be supported by antithesis, contrast, litotes, and hyperboles. The analysis shows that cameos receive mostly positive non-verbal emotion tracks and positive verbal reaction from characters of the work.

Published: September 2024

Clathrate hydrate-based technologies have been considered as promising and sustainable alternatives for the effective management of the climate change risks related to emissions of carbon dioxide, produced by human activities. This work presents a combined experimental and computational investigation of the effects of the operational procedures and characteristics of the experimental configuration, on the phase diagrams of CO2-H2O systems and CO2 hydrates formation, growth and dissociation conditions. The operational modes involved (i) the incremental (step-wise) temperature cycling and (ii) the continuous temperature cycling processes, in the framework of an isochoric pressure search method. Also, two different high pressure PVT configurations were used, of which one encompassed a stirred tank reactor and the other incorporated an autoclave of constant volume with magnetic agitation. The experimental results implied a dependence of the subcooling, (P, T) conditions for hydrate formation and dissociation and thermal stability of the hydrate phase on the applied temperature cycling mode, and the technical features of the utilized PVT configuration. The experimental findings were complemented by a thermodynamic simulation model and other calculation approaches, with the aim to resolve the phase diagrams including the CO2 dissolution over the entire range of the applied (P, T) conditions.
Activated Metabolic Transcriptional Program in Tumor Cells from Hepatoblastoma
Authors: Monge Claudia , Francés Raquel , Marchio Agnes , Pineau Pascal , Desterke Christophe , Mata-Garrido Jorge
Published: September 2024

(1) Background: Hepatoblastoma is the most common primary liver malignancy in children. During its development, metabolic reprogramming becomes particularly relevant due to the liver's intrinsic metabolic functions. Enhanced glycolysis, glutaminolysis, and fatty acid synthesis have been implicated in the proliferation and survival of hepatoblastoma cells. In this study we screened altered over expression of metabolic enzymes in hepatoblastoma tumors at tissue and single cell level. A hepatoblastoma tumor expression metabolic score was established and validated by machine learning; (2) Methods: Starting from Mammalian Metabolic Enzyme Database, bulk RNA-sequencing from GSE104766 dataset was investigated by supervised analyses (tumors versus adjacent liver tissue). Overexpressed enzymes in hepatoblastoma tumors were functionally enriched on KEGG metabolic database to draw a metabolic network with Cytoscape. Activated metabolic markers were used to compute a single-cell metabolic score in human and PDX hepatoblastoma samples from GSE180665 dataset (sc-RNAseq). ROC and area under curve (AUC) were computed on metabolic score. Elasticnet model tuning for metabolic marker expression was performed with r-caret on single cell transcriptome and revealed importance of individual marker to predict tumor cell status; (3) Results: Differential expression analysis on bulk transcriptome identified 287 significantly regulated enzymes between tumor and adjacent liver tissues: 59 of them were found overexpressed in tumors. 45 of the 59 over expressed enzymes were recognized in KEGG database which highlighted a main metabolic network enriched in amino acid metabolism but also carbohydrate, steroid, one carbon, purine, and glucoaminoglycan metabolisms. Based on expression of the 59 over expressed enzymes, the single cell metabolism score computed on GSE180665 dataset allowed to predict tumor cell status with and AUC of 0.98 (sensibility 0.93, specificity: 0.94). Elasticnet model tuned at 0.97 of AUC on individual marker single cell expression ranked top tumor predictive markers by decreasing importance: FKBP10, ATP1A2, NT5DC2, UGT3A2, PYCR1, CKB, GPX7, DNMT3B, GSTP1, and OXCT1; (4) Conclusion: An activated metabolic transcriptional program potentially affecting epigenetic functions was observed by bulk RNAseq in tumors of hepatoblastoma and confirmed at single cell levels in tumor cells.
Bridging the Gap: An Algorithmic Framework for Vehicular Crowdsensing
Authors: Jaimes Luis G , White Craig , Abedin Paniz
Published: September 2024

In this paper, we investigate whether greedy algorithms, traditionally used for pedestrian-based crowdsensing, remain effective in the context of vehicular crowdsensing (VCS). Vehicular crowdsensing leverages vehicles equipped with sensors to gather and transmit data to address several urban challenges. Despite its potential, VCS faces issues with user engagement due to inadequate incentives and privacy concerns. In this paper, we use a dynamic incentive mechanism based on a recurrent reverse auction model, incorporating vehicular mobility patterns and realistic urban scenarios using the Simulation of Urban Mobility (SUMO) traffic simulator and OpenStreetMap (OSM). By selecting a representative subset of vehicles based on their locations within a fixed budget, our mechanism aims to improve coverage and reduce data redundancy. We evaluate the applicability of successful participatory sensing approaches designed for pedestrian data and demonstrate their limitations when applied to VCS. This research provides insights into adapting greedy algorithms for the particular dynamics of vehicular crowdsensing.
Attitudes Towards Climate Change Among Wilderness Seekers
Authors: Próchniak Piotr , Ossowski Adam
Published: September 2024

The aim of the study was to explore attitudes towards climate change among wilderness seekers. The subjects were 273 (M=23.15; SD=7.72) adults. The respondents completed four questionnaires: Wilderness Novelty Seeking Scale, Wilderness Self-Efficacy Sale, Wilderness Courage Scale and Attitude Towards Climate Changes Scale.
There were three distinct profiles of the respondents: Curious, who are interested in the wilderness but lack the skills and courage to explore dangerous wilderness places; Adventurous, who actively seek experiences in dangerous wilderness places and have survival skills; and Indifferent, who have little interest in the wilderness. The participants in these profiles differed in terms of attitude toward climate change. The Curious and Adventurous groups were significantly more concerned about climate change. In addition, they were more likely to believe that climate change is already having a negative impact on the lives of people in the places where they live. Furthermore, the Curious group experienced positive feelings towards climate change less often than the Adventurous group. On the other hand, the Curious group experienced significantly more negative feelings in relation to climate change. Finally, wilderness seekers (Curious and Adventurous) were statistically more likely to engage in pro-environmental behaviors in the context of climate change compared to the Indifferent group.

Water samples for bacterial microbiome studies undergo a biomass concentration, DNA extraction and taxonomic identification steps. Through benchmarking, we studied the applicability of Skimmed milk flocculation (SMF) for bacterial enrichment, an adapted in-house DNA extraction protocol, and six 16S rRNA databases (16S-DBs). Surface water samples from two rivers were treated with SMF and Vacuum filtration (VF) and subjected to amplicon or shotgun metagenomics. A mock community standard underwent five DNA extraction protocols, taxonomical identification with six different 16S-DBs and evaluated by the Measurement Integrity Quotient (MIQ) score. In SMF samples, the skimmed milk was metabolized by members of lactic acid bacteria or genera such as Polaromonas, Macrococcus, and Agitococcus, resulting in increased relative abundance (p < 0.5) up to 5.0 log fold change compared to VF, rendering SMF inapplicable for bacterial microbiome studies. The best performing DNA extraction protocols were FastSpin Soil, the in-house method and EurX. All 16S-DBs yielded comparable MIQ scores within each DNA extraction kit, ranging from 61-66 (ZymoBIOMICs) up to 80-82 (FastSpin). DNA extraction kits exert more bias to the composition than the 16S-DBs. This benchmarking study presented valuable insights to inform future water metagenomic study designs.

The effect of initial immunosuppressive therapy on the kinetics of the SARS-CoV-2 vaccine-induced humoral response is unknown. Here, we compared the kinetics of SARS-CoV-2 vaccine-induced humoral response in chronic kidney disease patients undergoing kidney transplantation (KTRs) and compared to patients remaining on dialysis during the Omicron circulation. This prospective, non-randomized, real-world study included 113 KTRs and 108 patients on dialysis. Those with previous COVID-19 or negative IgG at screening were excluded. Blood samples were collected to assess SARS-CoV-2 IgG titers and neutralizing antibodies at months (M) 1, 3, 6, and 12. Seroreversion occurred in 1 KTR and in 3 patients on dialysis. KTRs had lower IgG titers over time (M1: 10,809.3±12,621.7 vs. 15,267.8±16,096.2 IU/mL; M3: 12,215.5±12,885.8 vs. 15,016.2±15,346.1 IU/mL; M6: 12,540.4±13,010.7 vs. 18,503.5±14,581.0 IU/mL; p=0.005), but Neutralizing antibodies were similar (M1: 94.0 vs. 90.3%; M3: 92.9 vs. 90.5%; M6: 99.0 vs. 95.5%; M12: 98.9 vs. 97.5%; p=0.812). During follow-up, KTRs received more vaccine (141 vs. 73; p<0,001) and had more COVID-19 (32.7% vs. 14.8%; p=0.002). Compared to patients on dialysis, KTRs had lower SARS-CoV-2 IgG titers and similar rates of seroreversion and neutralizing antibodies over time. Although KTRs received more boosters, they had a higher incidence of COVID-19.

This article compares the predictive capabilities of six models namely the Linear Discriminant Analysis (LDA), Logistic Regression (LR), Support Vector Machine (SVM), XGBoost, Random Forest (RF) and Deep Neural Network (DNN) to predict the default behaviour of credit card holders in Taiwan using data from the UCI machine learning database. Python programming language was used for data analysis. Statistical methods were compared with machine learning algorithms using the confusion matrix measured in metric terms of prediction accuracy, sensitivity, specificity, precision, G-mean, F1 score, ROC and AUC. The dataset contains 30,000 credit card user’s information with 6636 default observations and 23,364 non-default cases. The study results found that modern machine learning methods outperformed traditional statistical methods in terms of predictive performance measured by F1 score, G-mean and AUC. Traditional methods like logistic regression were marginally better than linear discriminant analysis and support vector machines in terms of predictive performance measured by area under the receiver operating characteristic curve. In the modern machine learning methods, deep neural networks were better in most of the predictive performance metrics than XGBoost and Random Forest methods.

Background/Objectives: Direct oral anticoagulants (DOACs) are first-line medications for stroke prevention in non-valvular atrial fibrillation (AF). However, variability in drug response poses risks of hemorrhagic or thromboembolic events. The role of genetics in determining DOAC safety is gaining attention, but evidence linking specific genetic polymorphisms to bleeding risk is lacking. Therefore, the aim of our study was to conduct an Exome-Wide Association Study with 198 non-valvular AF patients treated with rivaroxaban or apixaban, including 97 with bleeding complications and 99 without. Methods: DOAC plasma concentrations, 6-β-hydroxycortisol and cortisol levels in urine were measured for CYP3A4 phenotyping. Sequencing was performed on the DNBSEQ G-400 platform. Single nucleotide variants (SNV) associations with bleeding risk were assessed using logistic regression with additive, dominant, and recessive genetic models. Results: No SNVs reached Bonferroni-corrected significance in any genetic model. Polygenic risk scores (PRS) showed weak predictive ability for bleeding with apixaban. For rivaroxaban, regression indicated that ln Css min/D + 1 index increased with PRS, age, and 6-β-hydroxycortisol/cortisol ratio, but decreased with higher 6-β-hydroxycortisol and coronary heart disease presence. Conclusions: The findings revealed that the residual equilibrium concentration of anticoagulants, including dose-adjusted, cannot alone predict bleeding risk in non-valvular AF patients. No new genetic variants associated with bleeding risk were identified.

Background/Objectives: Traditional neurosurgical training involves a steep learning curve. The introduction of advanced simulation technologies, such as virtual reality (VR), provides an alternative method for skill acquisition, allowing for repeated practice and objective assessment. This study focuses on evaluating the learning curve associated with lumbar pedicle Kirschner wire insertion using a virtual fluoroscopic simulator among neurosurgical residents. Methods: Eighteen neurosurgery residents and two interns participated in this study. Participants’ initial skill levels were assessed through a questionnaire. Performance metrics, including insertion accuracy, time, and the number of virtual X-ray scans, were recorded across multiple attempts until a “practical learning plateau” was reached. Statistical analyses were conducted to model learning curves, assess the correlation between pre-training experience and performance. Results: The average number of attempts required to stabilize performance was 5.61. Learning rates varied, with some residents showing rapid improvement while others progressed more slowly. Higher accuracy in wire placement correlated with reduced usage on X-rays over time. However, experienced residents did not necessarily learn faster, indicating potential challenges in adapting to new simulation-based methods. Post-training feedback highlighted the simulator’s utility in increasing confidence and skill levels, although some limitations in anatomical accuracy were noted. Conclusions: This study demonstrates the potential of virtual simulation to enhance neurosurgical training by providing a controlled environment for repeated practice and objective feedback. Simulation-based training can effectively complement traditional methods, though individualized approaches may be necessary to accommodate varying learning rates among residents. Further refinement of simulation tools and their integration into standard training curricula are recommended.

Colorectal cancer (CRC) is characterized by a pro-inflammatory microenvironment and features high energy supply molecules that assure tumor growth. A still underestimated macromolecule is the Inorganic Polyphosphate (iPolyP), a high-energy linear polymer that is ubiquitous in all forms of life. Made up of hundreds of repeated orthophosphate units, iPolyP is essential for a wide variety of functions in mammalian cells, including the regulation of proliferative signaling pathways. Some evidence has suggested its involvement in carcinogenesis, although more studies need to be pursued. In this study, we tested the role of iPolyP on CRC proliferation, using in-vitro and ex-vivo approaches, in order to evaluate its effect on tumor growth. We found that iPolyP is significantly increased in tumor tissues compared to the corresponding peritumoral counterparts. In addition, iPolyP signaling occurs through the TRPM8 receptor, promoting CRC cell proliferation. Pharmacological inhibition of TRPM8 or RNA interference experiments showed that the involvement of TRPM8 is essential, greater than that of the other two known iPolyP receptors, P2Y1 and RAGE. The presence of iPolyP drives cancer cells towards the mitotic phase of the cell cycle by enhancing the expression of ccnb1, which encodes for the Cyclin B protein. In-vitro 2D and 3D data reflected the ex-vivo results, obtained by the generation of CRC-derived organoids, which increased in size. These results indicate that iPolyP may be considered a novel and unexpected early biomarker supporting colorectal cancer cell proliferation.

Information dissemination and preservation are crucial for societal progress, especially in the technological age. While technology fosters knowledge sharing, it also risks spreading misinformation. Audio deep fakes, convincingly fabricated audio using Artificial intelligence (AI), exacerbate this issue. We present Sonic Sleuth, an AI model for detecting audio deepfakes. Our approach leverages Deep Learning (DL) for a robust detection model. Meticulous data preprocessing and rigorous experimentation with various models led to the implementation of the most effective solution with a custom CNN model. Our comprehensive testing resulted in a highly accurate model (98.27% accuracy, 0.016 EER) trained on a substantial dataset of real and synthetic audio. In addition to an 84.92% accuracy and 0.085 EER on an external dataset, these results demonstrate Sonic Sleuth’s potential as a powerful tool against audio misinformation.
