PREVALENCE OF ESCHERICHIA COLI O157:H7 AND THE PRESENCE OF TOXIN GENES IN BUFFALO FECES AND MILK
Authors: Aslan Savaş , Kara Recep , Arslan Alparslan
Published: February 2025

Escherichia coli (E. coli) strains that produce Shiga toxin (stx) are among the most important causative agents of foodborne diseases. Cattle are the main reservoir of bacteria that can be transmitted to humans through the contaminated food chain. While Novobiocin-supplemented Tryptone Soy Broth (TSB) was used for bacterial pre-enrichment, the homogenate was first inoculated onto Cefixime Tellurite Sorbitol-MacConkey (CT-SMAC) agar and then onto 4-methylumbelliferyl-β-D-glucuronide (MUG)–Violet Red Bile Agar (VRBA) medium, respectively. Conventional and latex agglutination test methods identified colonies that did not ferment the sorbitol that grew here. Sorbitol-negative E. coli was detected in 32 (29.62%) of the buffalo feces samples and 23 (21.29%) of the raw milk samples. While the O157 antigen was detected in 9 (8.33%) of stool samples and 3 (2.77%) of raw milk samples, the H7 antigen was not found. With real-time Polymerase Chain Reaction, stx toxin was observed in 21 (18.44%) stool samples and 12 (11.11%) raw milk samples. Despite the absence of the H7 antigen in all of the samples studied, the presence of the O157 antigen and Shiga toxin-producing E. coli (STEC) toxin was detected at a high rate. To ensure the raw milk quality, the personnel working effectively and continuously in the milk production line should be trained on food safety/health and hygiene practices. In addition, stricter regulations and strategies should be determined to protect public health.

This study evaluated the effects of sodium butyrate (SB) supplementation on small intestine development in broiler chickens. Periodic acid-Schiff (PAS) and immunohistochemistry were used to undertake histological examinations of the duodenum, jejunum, and ileum. Duodenum, jejunum, and ileum histomorphometric data (villus length, crypt depth, goblet cell count), and interleukin-22 (IL-22) and toll-like receptor 8 (TLR8) immuno-stained area tissue coverage were quantified in control and SB supplemented groups. The histological changes in the SB supplemented group compared to the control group were as follows: There were increased villi lengths, widths, and crypt depths in the small intestine (duodenum, jejunum, and ileum). Increased numbers of goblet cells were observed, especially in the ileum. In addition, the lymphoid tissue within the small intestine was significantly larger (cross-section area=SB 34.8±0.5m2 vs control 13.2±0.5m2) and presented with more lymphoid nodules and more diffuse lymphoid tissue in the tunica submucosa, in the SB supplemented group compared to controls. Chickens do not have lymph nodes, therefore the mucosal-associated lymphoid tissue plays a major immunological role. Significant immunohistochemistry expression of IL-22 and TLR8 proteins were observed in the intestinal epithelial layer of the small intestine, which may play a role in protecting against many pathogens and gastrointestinal cancers

This research is part of a broader project that aims to make the didactic transposition of the knowledge produced by science about biodiversity for secondary education. To this end, the objectives of this specific article are to understand what students in the state of São Paulo know about the problems related to biodiversity in their area and their solutions, how this subject is addressed in textbooks and workbooks, and what their teachers say about the topic when talking about teaching biodiversity. The research is qualitative, with data collected through interviews with students and teachers and analyzed through immersion in the transcripts, coding, and establishment of categories and counting rules. The analysis of the teaching materials involved immersion, categorization and recording in a data matrix. In general, young people express a limited repertoire, pointing out one or another problem, with the most cited being the mistreatment of domestic animals and deforestation. They point to education and monitoring as solutions, lacking evidence of critical awareness of the responsibility of public and private authorities in mitigating the problems. Teaching materials can explore the topic further, for example, discussing the impact of species extinction on biodiversity, gas emissions and global warming, dam construction, and mining. Teachers have highlighted preservation and conservation as among the most critical topics to be worked on regarding biodiversity.

Published: February 2025

Improving quadcopter control systems poses significant challenges in unmanned flight technology development. Key issues include the intricate nature of PID and Kalman filter parameter settings, necessitating profound knowledge of system dynamics and sensor properties. Furthermore, successfully integrating the Kalman Filter with PID control demands meticulous coordination to optimize state estimation precision and system responsiveness. This research emphasizes the incorporation of the Kalman filter into PID-based control for quadcopter pitch angle regulation. The Proportional-Integral-Derivative (PID) approach governs pitch angle, augmented by the Kalman Filter, to enhance estimation accuracy and mitigate sensor uncertainty. Optimal outcomes during system response testing were achieved with parameters of Kp at 2.95, Ki at 0.23, and Kd at 0.02, resulting in superior oscillatory response, including a 9-degree overshoot, a 5-second rise time, a 15-second settling time, and a 0.15-degree steady-state error, showcasing effective regulation of the quadcopter pitch angle. A concurrent observation during testing indicated that including the Kalman filter led to a significantly reduced overshoot compared to tests without it; conversely, the settling time experienced considerable acceleration, while measurement accuracy in the steady-state condition improved by 50%.

Published: February 2025

Precision landing guidance is critical for aircraft safety, yet recurring signal anomalies in the ILS Glide Path on runway 24 at the Jakarta Air Traffic Service Center raise concerns about approach and landing reliability. Despite compliance with standard regulations, persistent signal anomalies affecting glide slope accuracy raise concerns about safe aircraft approach. This study investigates the sources of distortion, quantifies their impact on ILS Glide Path performance, and proposes mitigation strategies. Spectrum analysis, environmental assessments, and signal evaluation through oscilloscopes and navigation analyzers were employs to identify and quantify sources of distortion. Results indicate that while composite audio signals comply with standards, navigation analyzer readings reveal persistent deviations in Difference in Depth of Modulation (DDM) due to harmonic distortions at 30 Hz and its multiples up to 450 Hz. These distortions could interfere with DDM values received by calibration aircraft, making conventional technical adjustments, such as power level settings and antenna reconfigurations, insufficient for complete resolution. Instead, alternative mitigation approaches including reducing environmental reflections, optimizing siting criteria, and refining regulatory compliance measures are recommended. These findings provide valuable insights for enhancing ILS Glide Path reliability, refining signal mitigation strategies, and ensuring regulatory compliance for safer aviation navigation systems.

Published: February 2025

“Attieke”, a partially dehydrated fermented manioc root semolina (Manihot esculenta grantz) cooked in steam and agglomerated in appearance, undergoes a preparation process. This preparation uses hereditary or sometimes mechanised artisanal techniques, which do not sit well with current environmental principles. The aim of this study is to carry out an in-depth analysis of the environmental aspects, index and results associated with the activities, products and services involved in the manufacture of attieke in Abobo-Baoulé. The backbone of the methodology used to achieve this was made up of documentary research, observation of production sites, a field survey based on the ISO 14001 version 2015 standard and the Heineken procedure for assessing the environmental problems identified. This procedure was used to calculate the Environmental Hazard Coefficient (EHC) for each environmental aspect. A threshold of 26.66 was also calculated, at which point the significant aspects were determined. At the end of this process, five significant environmental aspects were selected. These were: the proliferation of cassava skins and storage of waste (CDE=36); the discharge of waste water from washing, humidification of the workplace, stagnation and run-off of waste water (CDE=60); unhygienic conditions and crushed cassava debris (CDE=36); waste water from pressing, etc. (CDE=36).
GEOMETRIC FEATURES: A CRITICAL COMPONENT FOR ACCURATE MALARIA PARASITE STAGE CLASSIFICATION IN THIN SMEAR MICROSCOPY
Authors: Aggarwal Gunjan , Goyal Mayank Kumar
Published: February 2025

Malaria-a global health problem always demands an accurate and timely diagnosis of a disease for its proper treatment. Traditional methods like microscopic examination are time-consuming and require specialized expertise. It thus poses challenges in resource-limited areas. Automated classification of malaria parasite stages helps in improving the diagnostic efficiency. In this paper, the importance of geometric features in malaria parasite stage classification using machine learning techniques has been realized. Geometric features, including area, perimeter, and shape descriptors, offer valuable information regarding the morphological differences between the various stages of the parasite. We compare the performance of the following machine learning models using geometric features: Random Forest, GaussianNB, XGBoost, and MLPClassifier. The results show that the inclusion of geometric features improves the accuracy and robustness of the machine learning models for classification. Among the different models tested in this study, MLP Classifier had 95.90% accuracy thus shows tremendous potential for a geometric feature in a malaria diagnosis program. This current study, therefore, gives way to advancement in automated diagnosis of malaria among others and further pursuit of geometric-based applications in their fields.

Published: February 2025

Chronic Kidney Disease (CKD) is an irreversible condition resulting in steady renal function deterioration. This decline impedes the ability of the body to regulate metabolism, fluids, and electrolytes. This paper reports the case of a young adult-aged male domestic cat, named Kuning, who was brought to the clinic with severe symptoms, including hematemesis, anorexia, and dehydration, and received intravenous fluid therapy via a 24G catheter. On the third day of hospitalization, ultrasonography revealed significant kidney abnormalities, including irregular cortical surfaces, indistinct cortico-medullary boundaries, focal hyperechoic areas in the cortex, and medullary ring sign. The urinary bladder appeared intact with an anechoic lumen. Liver ultrasonography revealed blunted edges in the right and left lobes and focal hyperechoic diffuse changes in the parenchyma, suggesting hepatic involvement. Following intensive treatment, Kuning's condition improved. Routine hematological tests on days 9 and 16-23 showed positive trends, with increased platelet counts and elevated leukocyte levels. Liver function improved compared to the initial assessments but remained outside the normal range. Based on anamnesis, clinical examination, and diagnostic findings, Kuning was diagnosed with CKD. After 27 days of intensive hospitalization, Kuning exhibited steady recovery, highlighting the importance of early diagnosis and comprehensive management in CKD cases.

The Impact of Leadership Styles on Effective Education Management
Authors: Yongli Han
Published: February 2025

Leadership styles play a pivotal role in shaping the effectiveness of education management, influencing institutional policies, stakeholder engagement, and academic outcomes. Effective leadership is essential for navigating the complexities of modern educational environments, ensuring institutions can adapt to evolving challenges. This paper examines the impact of transformational, transactional, and distributed leadership approaches on the management of educational institutions. Transformational leadership fosters innovation and collaboration by inspiring stakeholders to achieve a shared vision, encouraging creativity, and cultivating a culture of continuous improvement. Transactional leadership, in contrast, focuses on structure and accountability, utilizing performance-based rewards to drive efficiency and maintain institutional stability. Distributed leadership promotes shared decision-making and resilience by empowering individuals at all levels of the organization, fostering a sense of collective responsibility. By integrating theoretical frameworks, real-world case studies, and evidence-based practices, this paper explores how these leadership styles address critical challenges in education management. These challenges include optimizing resource allocation, enhancing teacher professional development, implementing inclusive policies, and promoting equity among diverse student populations. The analysis underscores the importance of adaptive leadership strategies in improving institutional performance, fostering inclusive environments, and ensuring long-term sustainability. The paper concludes by offering actionable recommendations for education managers to adopt leadership models best suited to their institutional contexts. By aligning leadership approaches with organizational goals, education leaders can cultivate a culture of collaboration, innovation, and resilience, ensuring sustained success in a dynamic and ever-evolving educational landscape. Effective leadership is not just about authority but about meaningful change that benefits all stakeholders in education.

Published: February 2025

Introduction: Meningiomas are rare tumors in children, accounting for around 3% of all pediatric brain tumors. Among them, primary intraventricular meningiomas (PIM) are even more exceptional, with an estimated incidence of between 0.5% and 5% of all meningiomas.

This article presents a case of intraventricular meningioma in a 7-year-old child, with a review of the literature.

Case Report: We report the case of an intraventricular meningioma in a 7-year-old child. He presented with symptoms of intracranial hypertension, and a cerebral MRI revealed an enhanced tumor at the intraventricular level of the right lateral ventricle. After surgical excision, histology showed a WHO grade I transitional meningioma. The postoperative course was favorable, with satisfactory radiological and clinical control.

Conclusion: Intraventricular meningiomas are rare in the pediatric population. These tumors are often large and aggressive when they occur in children. The management of these tumors is a surgical challenge.
Predictive modeling of microbial functionality from 16S rDNA sequences using machine learning
Authors: Abhaykumar Dalsaniya  , Urvisha Beladiya  , Ramesh K. Kothari
Published: February 2025

This study illustrates the possibilities for the use of machine learning algorithms integrating the prediction of microbial functionality regarding functional 16S rDNA sequences and filling the gap in mapping phylogenetic relations of the microbial context to their functionality. Previous 16S rDNA sequencing strategies have proven useful in describing microbial species, but not their functional potential. This study employed several sophisticated forms of supervised and unsupervised machine learning algorithms to interpret 16S rDNA data and predict the functional states of microbes in different contexts. The samples were obtained from public sources of genomic data. After the necessary pre-processing, the data were used to train different classifiers, including Random Forests, Support Vector Machines, and Neural networks. The results suggest that functional prediction enhancement using machine learning is effective because the algorithms reveal patterns and correlations in massive multifaceted genetic data. This improved possibility is closely related to areas such as medicine, environmentalism, and the practical application of bioengineering. This study also highlights data heterogeneity and model generalization issues and provides suggestions for improving predictive models for the future scope of microbial genomics.

Sexo pensante, sexo cambiante: la educación media y superior de las españolas en los años cincuenta
Authors: Morcillo Gómez Aurora
Published: February 2025

La universidad franquista se regularía por la Ley de Odernación Universitaria de 1943, en vigor hasta 1970. En este artículo la autora sostiene que, lejos de excluir a las mujeres explicitamente de la educación superior, el régimen promueve un ideal de mujer católica o “true Catholic womanhood” intrínsecamente opuesto al sujeto universitario definido en la letra de la ley. La educación media que en los años cincuenta se regula mediante dos reformas legales, se diseña de tal modo que a las jóvenes se las desanimaba a estudiar o si lo hacian a elegir una carrera apropiada a su sexo. El artículo se centra en los años cincuenta, cuando el franquismo entra en la transición de la autarquía al consumismo y las relaciones de género se han de redefinir para amoldarse a las circunstancias.

Culture of scientific thinking as a research problem
Authors: Kovalchuk Larysa
Published: February 2025

The article, based on the conceptual and terminological analysis of scientific literature, clarifies the approaches of scholars to the interpretation of the essence of the system-forming, generic and species concepts of research. Given that the fundamental categories (“science”, “culture” and “thinking”) are system-forming, “scientific culture”, “scientific thinking” and “culture of thinking” are considered generic within the framework of scientific research. Scientific culture is defined as an integral formation of a researcher’s personality that characterizes the degree of his or her excellence in the scientific field, scientific outlook, intellectual potential, and system of competencies. Scientific thinking is defined as a special type of researcher’s thinking, characterized by logic, systematicity, objectivity, validity, conceptuality, depth, predictability, originality, creativity, insight, aimed at understanding pedagogical reality and ensuring the reliability, accuracy and validity of the results obtained in the process of research.
The phenomenon of “culture of scientific thinking” is substantiated as a species concept in relation to generic ones. The culture of scientific thinking of the researcher is interpreted as an integrated formation that determines the style of his/her cognitive activity, the content of scientific knowledge, individual characteristics of the personality, forms an idea of the problem of scientific research, approaches to substantiating theoretical-methodological and methodological-technological foundations, contributes to the modeling of the research program, the choice of diagnostic tools for the study and the interpretation of its results. In the context of studying the research activities of higher education students, the main aspects of the formation of a culture of scientific thinking are identified.

Despite the fact that the green finance market in Russia is actively developing, its growth rates still lag behind foreign countries. In order to create incentives to include ESG agendas in the strategic plans of the industrial sector, as well as to adapt financial market participants to new types of risks associated with sustainable development, it is necessary to identify and solve a number of organizational and economic problems. In particular, it is necessary to determine barriers to the development of sustainable investment in ESG projects from the perspective of the real economy sector, which determines the relevance of the study. The purpose of the study was to identify the reasons for the low spread of ESG projects in the activities of the large industrial sector of the Ural region in order to adapt the implementation of the ESG agenda to the needs of enterprises and the national interests of the Russian Federation. The objectives of the study included identifying the attitude of large industrial enterprises in the Ural region to the ESG agenda in terms of corporate and legal issues and operational activities and attitudes to the climate and environmental agenda, as well as determining the readiness of large businesses to use green finance and to disclose information about non-financial reporting and risks. The methodological basis of the study was the results of a questionnaire survey of management personnel responsible for consolidating ESG policy at large industrial enterprises in the Ural region. The results are as follows. All the companies surveyed expressed concerns that disclosure of information in ESG reporting could be used by unfriendly countries for political purposes or by other entities as an instrument of unfair competition. At the same time, the respondents demonstrated significant attention to the negative environmental impact of production activities. In the matters of the climate agenda, respondents are currently guided by legislative requirements. Insufficient attention is also paid to ESG training of personnel. The findings can be useful for creating incentives to include the ESG agenda in the strategic plans of the industrial sector, as well as for adapting green finance market players to new types of risks associated with sustainable development.

The analysis shows that these instruments have existed for decades, but have gained prominence in the XXI century. Their recognition as indispensable tools for mitigating risks to private capital, particularly political risks, has been reflected in more mentions in milestone policy documents, organizational and intellectual efforts to revise statistical reporting rules and larger volumes of private finance mobilized. However, available OECD data show insufficient use of guarantees for development purposes, extreme disproportions in mobilized finance among providers (both bilateral and multilateral), beneficiary countries and sectors and a high portfolio heterogeneity. The prospects of the distribution of guarantees will be influenced by new statistical reporting principles and a number of powerful economic and noneconomic factors, such as: 1) a lack of progress on the Sustainable Development Goals; 2) worsening budgetary constraints in developed countries, hindering the increase in official development assistance; 3) intensifying geopolitical rivalries. A possible increase in the provision of development guarantees can only be welcomed. However, if it is accompanied by a reduction in funding for traditional aid programs affecting the fundamental factors of commercial and non-commercial risks, as well as prioritization of less vulnerable but more strategically important countries, the positive effect will fall short of expectations.
Fractal Holographic Emergent String Theory (FHEST) PART G Mapping of Fractal Cartan Formulas to Traditional Cartan Formulas

Published: February 2025

This paper explores the mapping relationship between the fractal Cartan for?mula and the traditional Cartan formula within the framework of Fractal Holo?graphic Emergent String Theory (FHEST). By introducing fractal dimension cor?rection factors, non-local differential operators, and curvature integral terms, weestablish a rigorous mapping between the fractal Cartan formula and traditionalgeometric frameworks. This mapping not only preserves the mathematical struc?ture of classical theories but also reveals the regulatory role of multi-scale geometryon physical laws through fractal correction terms. We validate the restoration ofthis mapping in the classical limit, the consistency of fractal field equations, andexperimental observability, demonstrating its physical self-consistency.

The Wave Function of the Void: A Hidden Parameter of Reality and the Foundation of Three-Dimensional Manifolds
Authors: Preece Andrei
Published: February 2025

The Silent Architect of RealityThe Wave Function of the Void (Ψ_void) offers a revolutionary perspective on the nature of reality, unifying concepts from physics, mathematics, and philosophy. It demonstrates that the current model of an open, flat Universe corresponds only to a local approximation of the surface of a three-dimensional sphere. However, the Wave Function of a three-dimensional manifold diverges fundamentally from the flat, open, expanding space, providing a complete and consistent framework that aligns with empirical observations.Beneath the illusion of form, beyond the fabric of space-time, lies the Void—not emptiness, but the hidden code of existence itself. The Wave Function of the Void (Ψ_void) is not a mere equation; it is the forgotten language of the cosmos, a cipher unlocking the true topology of reality.This groundbreaking work obliterates the outdated notion of a purely expanding universe, revealing instead a dynamic, self-organizing structure where space itself is a living, breathing entity. Ψ_void describes the fractal resonance of energy densities, where the vacuum is not absence, but a field of infinite potential—the source code of everything.Inside this work, you will discover:The Void as the Engine of Existence – where quantum fluctuations are not noise, but the rhythm of a deeper order.The Light Spheres of Creation – how the universe cycles through expansion and recursion, forming an eternal breathing cosmos.The Hidden Connection Between Dark Energy and Light Pressure – proving that acceleration is not a mystery, but a manifestation of the Void's own harmonic structure.Ψ_void is not a theory. It is the next step in understanding reality itself—a revelation that transcends physics, philosophy, and time. Are you ready to see beyond the veil? Download now. Namaste
Is it Worth the Hustle? A Multi-Country Replication of the Effort Moralization Effect and an Extension to Generational Differences in the Appreciation of Effort
Authors: Roth Leopold Helmut Otto , Tissot Tassilo
Published: February 2025

Inferring moral character of individuals is an adaptive need for social decision-making. The effort moralization effect describes the finding that people who exert more effort in a task are seen as more moral, even if higher effort does not enhance the outcome (e.g., higher performance or better quality). We replicated this effect, based on Celniker et al. (2023, Study 6), in countries not yet investigated (Germany and Mexico). Further, drawing on discussions around workforce participation (see ‘great resignation’ or ‘quiet quitting’) criticizing the lower work ethic of younger individuals (e.g., the so-called Gen Z), we tested whether (ineffective) effort is moralized less in younger individuals. Our findings support the generalizability of effort moralization to Germany and Mexico, yet point to heterogeneity in effect strength. However, our findings do not support the hypothesis that effort moralization increases with age. We discuss further implications and limitations of these findings and suggest avenues for future research on effort moralization.Keywords:
#BloodDonation: How European Blood Banks Use Social Media to Reach Donors and Non-Donors

Published: February 2025

In recent years, social media has become increasingly central to the communication strategies of non-profit organizations. While the body of research on social media use in philanthropy is extensive and growing, it predominantly focuses on monetary donations. Studies examining the role of social media in facilitating non-monetary contributions, such as blood product donations, remain fragmented and lack a comprehensive perspective. This study addresses this gap by exploring how European blood banks use social media to engage with donors and non-donors. Drawing on 22 interviews with communication specialists from 13 countries, we examine communication objectives, strategies, content types, performance measurement and emerging trends and practices. We are contextualizing our findings within the broader intersections of non-profit communication, medical communication, and donor behavior, and provide actionable insights for practitioners and a foundation to bridge academic research and practice. These findings are not only useful for blood banks but are broadly generalizable to other non-profit contexts.
Language Models for standardising clinical notes and information extraction in addiction psychiatry – an empirical study
Authors: Shukla Lekhansh
Published: February 2025

Introduction: Electronic Health Records (EHR) contain both structured and unstructured data, with unstructured clinical notes (CNs) widely used in addiction psychiatry. CNs have numerous errors and require proofreading before downstream applications. This study evaluates NLP methods and adapts a Language Model (LM) for proofreading CNs and extracting substance-related information.Methods: We analysed CNs from a five-year addiction medicine EHR dataset (2018-2023), selecting 6,500 notes. The proofreading task involved correcting spelling, expanding abbreviations, while information extraction (IE) identified substance use presence and quantified the time since last use. Annotations by a team of doctors and nurses provided the gold standard. Against this, we compared performance of existing solutions including LMs and adapted an LM for these tasks. The final model is also compared against state-of-the-art commercial model (Gpt-4-o) and an acceptability-distinguishability experiment is done with masked raters.Results: Proofreading improved readability and decreased out-of-vocabulary words. LM-based solutions outperformed simpler approaches. The final model performed better than Gpt-4-o on both tasks. Human evaluators found model-corrected CNs indistinguishable from human-proofread versions, correctly guessing the identity in only 27.9% instances and preferring model outputs in 55.7%. On the IE task, while the overall performance is satisfactory (Mean F1 0.99), it is poor on rarer substance classes like hallucinogens.Discussion and Conclusions: Fine-tuned LMs effectively standardized CNs and extracted structured information from addiction psychiatry records. It is possible to adapt open-source LMs for bespoke tasks in addiction psychiatry with limited computational resources. This standardisation can enable large-scale dataset collations for deep learning based predictive modelling.
F0 and voice quality of coarticulated Mandarin tones
Authors: Huang Yaqian
Published: February 2025

The final published version can be found here: https://doi.org/10.1177/00238309251315081Tonal coarticulation occurs when adjacent tones affect the production of each other, and this often induces changes in both F0 and voice quality of the tones. In Mandarin, F0 height of the target tone is affected by adjacent tones through both carryover assimilation and anticipatory dissimilation (Xu, 1997). Additionally, voice quality is found to be largely dependent on F0, such that lower F0 induces creakier quality, regardless of tone (Kuang, 2017). Given this dependency of voice quality on F0, it is unclear how this interaction manifests in the context of coarticulated tones. The present study investigates the relationship between F0 and voice quality changes in coarticulated tones in three-tone sequences. Voice quality is assessed both acoustically and articulatorily using electroglottography (EGG). Our study confirms both carryover and anticipatory effects on F0. Changes in voice quality are largely expected from the direction of F0 changes. However, some tone-specific exceptions are present, which we interpret as support for the (potential) independence of voice quality from F0.

本文以数的结构理论为基础，尝试从本质上探索角谷猜想的答案，并对角谷猜想中的一些现象，如冰雹现象中波峰、波谷的出现，绕不开的5，为什么直接回到1，无大数循环等，进行解释，并将这一猜想扩展为3x+t的形式。并且基于数的结构理论，推导出一个通用的D平衡公式。Based on the theory of number structure, this article attempts to fundamentally explore the answer to the corner valley conjecture, and explains some phenomena in the the corner valley conjecture, such as the appearance of peaks and troughs in the hail phenomenon, the inescapable 5, why it directly returns to 1, and the absence of large number cycles. It also extends this conjecture to the form of 3x+t.And based on the structural theory of numbers, derive a universal D balance formula.
