Authors: Ghelichkhan Siavash , Gibson Angus , Davies D. Rhodri , Kramer Stephan C. , Ham David A.
Published: November 2023

Abstract. Reconstructing the thermo-chemical evolution of Earth's mantle and its diverse surface manifestations is a widely-recognised grand challenge for the geosciences. It requires the creation of a digital twin: a digital representation of Earth's mantle across space and time that is compatible with available observational constraints on the mantle's structure, dynamics and evolution. This has led geodynamicists to explore adjoint-based approaches that reformulate mantle convection modelling as an inverse problem, in which unknown model parameters can be optimised to fit available observational data. Whilst recent years have seen a notable increase in the use of adjoint-based methods in geodynamics, the theoretical and practical challenges of deriving, implementing and validating adjoint systems for large-scale, non-linear, time-dependent problems, such as global mantle flow, has hindered their broader use. Here, we present the Geoscientific Adjoint Optimisation Platform (G-ADOPT), an advanced computational modelling framework that overcomes these challenges for coupled, non-linear, time-dependent systems. By integrating three main components: (i) Firedrake, an automated system for the solution of partial differential equations using the finite element method; (ii) Dolfin-Adjoint, which automatically generates discrete adjoint models in a form compatible with Firedrake; and (iii) the Rapid Optimisation Library, ROL, an efficient large-scale optimisation toolkit; G-ADOPT enables the application of adjoint methods across geophysical continua, showcased herein for geodynamics. Through two sets of synthetic experiments, we demonstrate application of this framework to the initial condition problem of mantle convection, in both square and annular geometries, for both isoviscous and non-linear rheologies. We confirm the validity of the gradient computations underpinning the adjoint approach, for all cases, through second-order Taylor remainder convergence tests, and subsequently demonstrate excellent recovery of the unknown initial conditions. Moreover, we show that the framework achieves theoretical computational efficiency. Taken together, this confirms the suitability of G-ADOPT for reconstructing the evolution of Earth's mantle in space and time. The framework overcomes the significant theoretical and practical challenges of generating adjoint models, and will allow the community to move from idealised forward models to data-driven simulations that rigorously account for observational constraints and their uncertainties using an inverse approach.

Authors: Schielicke Lisa , Li Yidan , Schyns Jerome , Sperschneider Aaron , Solano Marchini Jose Pablo , Gatzen Christoph Peter
Published: November 2023

Abstract. We introduce an innovative two-week educational block course held at the University of Bonn during the 2023 winter semester, focusing on Cloud Model 1 (CM1) and its convection-permitting capabilities. During the course, students gained essential skills in setting up and customizing CM1 simulations on high-performance computing clusters, while delving into deep moist convection dynamics. An additional introduction to three-dimensional visualization software allowed the participants to transform numerical data into compelling visualizations, deepening their insights into cloud dynamics. Students applied their gained knowledge in research projects of their own choice that will be presented here and in the supplementary material.

Abstract. This study presents the simulated response of regional climate and the oxygen isotopic composition of precipitation (δ18Op) to different along-strike topographic evolution scenarios. These simulations are conducted to determine if the previously hypothesized diachronous surface uplift in the Western and Eastern Alps would produce δ18Op signals in the geologic record that are sufficiently large and distinct to be detected using stable isotope paleoaltimetry. We present a series of topographic sensitivity experiments conducted with the water-isotope-tracking atmospheric general circulation model (GCM) ECHAM5-wiso. The topographic scenarios are created from the variation of two free parameters, (1) the elevation of the Western–Central Alps and (2) the elevation of the Eastern Alps. The results indicate Δδ18Op values (i.e., the difference between δ18Op values at the low- and high-elevation sites) of up to −8 ‰ along the strike of the Alps for the diachronous uplift scenarios, primarily due to changes in orographic precipitation and adiabatic lapse rate driven localized changes in near-surface variables. These simulated magnitudes of Δδ18Op values suggest that the expected isotopic signal would be significant enough to be preserved and measured in geologic archives. Moreover, the simulated slight δ18Op differences of 1 ‰–2 ‰ across the low-elevation sites support the use of the δ–δ paleoaltimetry approach and highlight the importance of sampling far-field low-elevation sites to differentiate between the different surface uplift scenarios. The elevation-dependent rate of change in δ18Op (“isotopic lapse rate”) varies depending on the topographic configuration and the extent of the surface uplift. Most of the changes are significant (e.g., −1.04 ‰ km−1 change with slope error of ±0.09 ‰ km−1), while others were within the range of the statistical uncertainties (e.g., −0.15 ‰ km−1 change with slope error of ±0.13 ‰ km−1). The results also highlight the plausible changes in atmospheric circulation patterns and associated changes in moisture transport pathways in response to changes in the topography of the Alps. These large-scale atmospheric dynamics changes can complicate the underlying assumption of stable isotope paleoaltimetry and therefore require integration with paleoclimate modeling to ensure accurate reconstruction of the paleoelevation of the Alps.
Reeleição virtual de Lula
Authors: Miranda Leão Martins Joyce
Published: November 2023

Este artigo parte de uma hermenêutica da profundidade, proposta por Thompson (1995), para analisar as condições sociais de produção e emergência dos discursos na apresentação da candidatura de Dilma Rousseff, em 2010. Julga-se que observar a constituição da liderança de Dilma colabora tanto na compreensão do seu impeachment quanto na reflexão sobre o papel da imagem das lideranças na atual democracia brasileira. Os resultados da análise indicam que Dilma representou a possibilidade de uma eleição virtual do então presidente Luiz Inácio Lula da Silva. Suas imagens como mãe e como gestora tiveram força porque vieram amparadas no ethos de herdeira de Lula e de corresponsável pelos êxitos dos governos federais petistas.

Published: November 2023

Este artigo traz uma discussão sobre os elementos característicos da produção científica sobre comunicação e gênero no Brasil, a partir de uma análise bibliométrica do que se tem desenvolvido em termos de pesquisa com o objetivo de compreender os avanços, lacunas e possibilidades que esta subárea de estudos possui em sua trajetória. Utiliza-se como unidade de análise a produção acadêmica dos pesquisadores em periódicos, o que representa uma das características estruturantes de um campo científico. Assim, foram analisados 168 artigos publicados em onze revistas pertencentes aos estratos A1 e A2 na área da Comunicação e Informação na CAPES. Para este artigo, foram discutidos os dados relacionados a três eixos, a saber: i) distribuição institucional e de formação dos pesquisadores; ii) temáticas e objetos contemplados; iii) características e vertentes analíticas dos estudos. Percebeu-se concentração de pesquisadores no eixo Sul-Sudeste, sendo a maioria mulheres com titulação de doutorado. Quanto aos temas, Cinema e Jornalismo se sobrepõem ante as demais subáreas de estudo. Tem-se ainda foco nos conteúdos e majoritariamente os trabalhos são empíricos.
Jornalismo esportivo para a cultura de paz
Authors: Ramalho Orlando Matheus , Napolitano Carlo José , Cabral Raquel
Published: November 2023

Este artigo propõe aproximações teóricas e empíricas entre o jornalismo esportivo e o jornalismo para a cultura de paz, o que resultaria na aplicação, na mídia esportiva, de conceitos e preceitos do jornalismo para a paz. O texto apresenta os conceitos de violência direta, estrutural e cultural e de paz positiva e paz negativa, conforme ensina Johan Galtung, e discute a necessidade da comunicação para a paz e do jornalismo para a paz. Em seguida, defende o estabelecimento do jornalismo esportivo para a cultura de paz, já que o mundo do esporte é acometido por inúmeras manifestações de violência direta, estrutural e cultural. Contudo, a mídia especializada tende a abordar esse tipo de acontecimento de maneira superficial ou apenas no calor dos acontecimentos, sem se aprofundar em causas ou desdobramentos e sem tentar ampliar os olhares e ouvir mais lados envolvidos ou interessados na questão, apontando culpados e atendo-se a fontes oficiais. Assim, um jornalismo esportivo para a paz não apenas é necessário como oferece amplo escopo de investigação acadêmica – o esporte é trespassado por questões como conflitos entre torcedores, violência policial, elitização, racismo, homofobia, xenofobia, machismo e variadas demonstrações de violência. Espera-se que este artigo possa embasar futuras pesquisas, para que o jornalismo esportivo para a cultura de paz ganhe adesão em termos acadêmicos, nas universidades, e profissionais, na mídia esportiva de fato.

Published: November 2023

O presente trabalho pretende refletir sobre a relação entre imagem e texto, que são postas em circulação no jornalismo digital, a partir da análise em cinco perfis noticiosos do Instagram, entre janeiro de 2018 e junho de 2020. A partir de métodos de pesquisa para a internet (FRAGOSO; RECUERO; AMARAL, 2011) e também da pesquisa qualitativa com texto, imagem e som, bem como análise de conteúdo e análise do discurso (BAUER; GASKELL, 2008), foi traçada uma pesquisa sobre a conduta do jornalismo ambiental e científico que se tem produzido a partir de assuntos sobre a Amazônia e Meio Ambiente. Os resultados apontam para imagens fotográficas genéricas, muitas vezes sem identificação de origem e/ou autoria, utilizadas para ilustrar o tema ou causar impacto. Memes, montagens e ilustrações fazem parte desse universo imagético, amplamente utilizadas junto a um jornalismo Opinativo, que alia denúncia e posicionamento de oposição ao governo federal em exercício durante o período analisado, com maior ênfase sobre o de Jair Messias Bolsonaro.

Factor analysis of the MEQ43 suggests non-psychedelic mystical experiences are different from psychedelic mystical experiences
Authors: Formoso Kirsti A.
Published: November 2023

This study aimed to determine whether the 30-item Mystical Experience Questionnaire (MEQ30) is suitable for measuring non-psychedelic mystical experiences or whether a subset of questions from the 43-item Mystical Experience Questionnaire (MEQ43) is more appropriate. Participants (N = 136) completed an online survey about their non-psychedelic mystical experience, which included the MEQ43 and its subset of items that make up the MEQ30. Confirmatory Factor Analysis revealed that the MEQ30 was not a good fit for the present study’s non-psychedelic sample. Exploratory Factor Analysis of the MEQ43 suggested that an alternative set of items and corresponding factors may be more appropriate. In the new four-factor instrument (MEQ25), 25 items account for all MEQ43 factors. The new factors are Sacred Unity, Noetic Quality, Time-Space Transcendence, and Ineffable and Paradoxical. The new scale demonstrated excellent internal reliability (α = .93) and strong convergent validity with the M-Scale. The new scale is unique because it has a separate factor for noetic quality, which is considered a salient and therapeutic aspect of mystical experience. Furthermore, the refined time-space subscale better reflects the theory and subjective experience of non-psychedelic mystical experiences.

Published: November 2023

Introduction: Malignant transformation of epidermoid cysts is rare, it accounts for 1% of all diagnosed cysts. Transformation into squamous cell carcinoma and basal cell carcinoma can occur. Clinical examination, radiological examination, and pathological confirmation are necessary for diagnosis and the treatment of choice is usually surgical excision.

Case Report: A 57-year-old Syrian female patient presented to our hospital with a huge mass on the back. Computed tomography revealed a subcutaneous huge mass 25.0 × 20.0 × 9.0 cm extended from cervical vertebrae level into upper lumbar vertebrae. Surgery with the intent of wide and complete excision was performed but it was difficult to obtain complete excision of tumor because of extension into the deep muscles. The diagnosis was made by histopathologic examination. It was a malignant transformation into squamous cell carcinoma arising from the epidermoid cyst. The patient received radiotherapy after surgery because of incomplete excision of tumor.

Conclusion: This case shows an unusual presentation of a huge epidermoid cyst on the back with transformation into malignancy. We aimed to highlight the importance of early diagnosis and treatment of these cysts.

Sabe-se que pessoas com diabetes enfrentam um risco elevado de doenças renais e cardiovasculares, resultando em diminuição da qualidade e expectativa de vida. Assim, é importante ressaltar que a doença renal diabética (DRD) é uma das complicações mais comuns do diabetes. Os inibidores do cotransportador de sódio-glicose-2 (ISGLT2) foram inicialmente desenvolvidos e aprovados como medicamentos redutores de glicose com o mecanismo único de induzir glicosúria em pacientes com diabetes tipo 2. Portanto, os inibidores do SGLT2 foram propostos para fornecer efeitos cardioprotetores e renoprotetores adicionais além dos mecanismos de promoção da glicosúria, visando evitar a progressão para doença renal terminal, intervir nos eventos cardiovasculares e evitar a morte. Dessa forma, com o crescente corpo de literatura sobre o uso dos ISGLT2 na doença renal do diabetes, foi possível a realização de uma revisão integrativa de literatura por meio da plataforma pubmed, com seleção e análise criteriosa dos artigos, a fim avaliar o uso desses medicamentos como uma nova estratégia terapêutica para a doença renal do diabetes, comparando sua eficácia, segurança e prognóstico com as terapias convencionais. Nesta revisão observou-se que a descoberta e o desenvolvimento de inibidores do SGLT-2 proporcionaram uma nova abordagem para o controle dos níveis de glicose no sangue em indivíduos com doença renal. Esse medicamento oferece proteção contra desfechos cardiovasculares e renais em pacientes com DRC, com e sem diabetes. Logo, fica evidente uma vantagem dos ISGLT2 em comparação aos demais medicamentos, como os inibidores do GLP-1RA e do DPP-4 no tratamento da doença renal do diabetes. Entretanto, maiores investigações e esclarecimentos são necessários para compreender completamente os mecanismos interligados e os efeitos protetores renais dos inibidores do SGLT-2.
O que o cirurgião-dentista precisa saber sobre o vírus linfotrópico de células T humana (HTLV)
Authors: De Souza Daniel Nascimento Carvalho , Dantas Rebeca Carolina Moraes
Published: November 2023

O vírus linfotrópico das células T humanas tipo 1 (HTLV-1) está relacionado a diversas manifestações clínicas como a Leucemia/Linfoma de célula T do adulto (ATL) e a Paraparesia espástica tropical (TSP), além de alterações imunológicas. O HTLV-1 tem uma alta prevalência na população brasileira. Sua transmissão ocorre através das vias sexual, parenteral e vertical e o diagnóstico é feito através de exames laboratoriais. O objetivo do presente trabalho foi fazer o levantamento de informações destinadas a cirurgiões dentistas acerca do HTLV-1, seu diagnóstico, e possíveis manifestações orais relacionadas. Realizou-se uma revisão bibliográfica através de pesquisas feitas nas bases de dados PubMed e Google Acadêmico. A infecção pelo HTLV-1 pode estar associada a síndrome de Sjögren, que pode acometer a cavidade bucal e as glândulas lacrimais e salivares. Os medicamentos utilizados no controle das doenças podem apresentar efeitos colaterais sobre a cavidade oral, modificando o processo de salivação. Com a redução do fluxo salivar o indivíduo tem maior risco de cárie, doença periodontal e a predisposição a doenças oportunistas como a candidíase. Nesse sentido, ressaltasse a importância do cirurgião-dentista na equipe multidisciplinar de acompanhamento do paciente HTLV positivo.

O presente trabalho tem como objetivo analisar, por meio da Análise do Discurso de vertente francesa, a lei municipal 2.265, criada em 2021 pelo vereador Clébio Ramos de Souza, do partido Republicanos, em Pontes e Lacerda. Trata-se de uma lei que afirma tentar preservar a Língua Portuguesa culta por meio da proibição da chamada Linguagem Neutra (Linguagem Não-Binária) nos institutos educacionais da cidade. Desta forma, a partir da interpretação do significado da linguagem de uma maneira complexa, levando em consideração a formação ideológica, as condições de produção e a subjetividade do sujeito, nos propomos a analisar a lei e a entrevista do vereador Clébio para a TV local, sendo possível observar a vinculação ideológica a religiões de natureza pentecostal na construção desta lei, que não está disposta a resguardar a norma culta, mas sim, evitar o uso da variação linguística por parte das pessoas não-binárias.

Study on the Influence of Cotton Option Launch on The Price Fluctuation of Underlying Futures
Authors: Liu Wenmei
Published: November 2023

This paper takes cotton options as the research object, and empirically tests the impact of cotton options on the price fluctuation of the underlying futures in the short and medium term by establishing the ARMA-GARCH model with the introduction of two dummy variables. The study found that the launch of cotton options increased the volatility of the underlying futures price in the short term, and increased the volatility in the medium and long term. After the launch of cotton options, the supply of national policies against the epidemic played a certain stabilizing role in the volatility of futures prices, but the policy effect has a time lag. Based on this, institutional investors should be encouraged to use cotton options and futures risk management, build a risk prevention and control mechanism for sudden public crisis events, popularize the knowledge of options and futures, and improve the transparency of cotton trading.

Authors: Yuan Xuemei , Jin Shuai , Qiao Na
Published: November 2023

Subject to the realistic dilemma of insufficient supervision ability, the incomplete internal control supervision of scientific research projects will exist widely in colleges and universities in China for a long time and tend to be normal. Furthermore, exploring and designing effective internal control regulation strategies to deal with the violations of the research group have become an urgent practical problem to be solved in the internal control of colleges and universities. Based on the key supervision of the research group in Colleges and universities, this paper deeply discusses the dynamic choice of compliance behavior, the effectiveness of regulation strategy and its optimal design of the research group under the key supervision mechanism by using the method of game analysis. The research shows that under the condition of obvious constraints on the ability of school supervision, the carefully designed key supervision mechanism can become a powerful tool to guide and control the benign behavior of research groups in Colleges and universities.
Research on Financial Risk Factors under the Perspective of Cross-border Mergers and Acquisitions of Chinese Enterprises
Authors: Luo Tianyu
Published: November 2023

Chinese enterprises are increasingly participating in cross-border mergers and acquisitions (M&A). However, due to the complexity of the M&A process, poor decision-making often leads to financial risks after the completion of the M&A. Therefore, this study aims to explore the influencing factors of financial risks in cross-border M&A. The research selected 67 listed companies that engaged in cross-border M&A transactions from 2018 to 2021 as the research sample. The Z-score model was utilized to measure financial risks, and a financial risk influencing factor index system was constructed based on literature research and factor analysis to assess the financial risk status and influencing factors before and after cross-border M&A transactions. The findings of this study reveal that cross-border M&A significantly increases financial risks for enterprises, and the payment and financing stages are key factors influencing the financial risks of cross-border M&A transactions.

Authors: Xiang Yushen
Published: November 2023

The development of intelligent manufacturing has significantly impacted the traditional manufacturing industry, so it is urgent to change the traditional business model and production mode. As the world economy is in a downturn, small and micro enterprises in the subordinate position of the supply chain are facing a considerable threat. On the one hand, the substitutability is substantial; there is no bargaining power, which makes the enterprise's anti-risk ability 0. On the other hand, it is subject to significant restrictions, and the core enterprise thunder will protect all of the enterprises in the chain. This paper focuses on the risk identification and transformation mechanism of micro and small enterprises and whether micro and small enterprises have the conditions for transformation and upgrading in the context of the Internet. Based on the Bayesian formula, the AHP method model is the theoretical basis to help enterprises make decisions.
Resistencias caleidoscópicas al capitalismo contemporáneo: género, trabajo y despojo
Authors: Brown Brenda , Cufré Sara , Garcés Santiago
Published: November 2023

Escribir la introducción a este número especial nos llena de alegría. Es el signo de la inminente llegada de ese final que cristaliza, en papel, el trabajo de muchos años. La síntesis colectiva de vínculos interdisciplinarios, de reflexiones transfronterizas, de cuerpos rebeldes con miradas críticas. Quienes editamos este dossier nos conocimos compartiendo espacios dedicados al estudio de la relación entre capital y trabajo, entre tesis de maestrías y de doctorados. Compartimos jornadas académicas y también días de lucha. Dedicamos horas de debate y trabajo colectivo que condujeron a este punto de llegada en el que reivindicamos una mirada caleidoscópica del capitalismo en el siglo XXI. 

Abya Yala (América Latina) atraviesa una crisis multifacética que combina la intensificación del extractivismo con el avance de las “nuevas derechas”, reformas que marcan retrocesos en derechos sociales con la precarización de las vidas, crisis de ingresos y endeudamiento masivo, nuevas formas de desposesión a partir del terror y el avance del crimen organizado. 

Las múltiples formas de precarización de las vidas están ancladas en una matriz extractivista, de explotación y desposesión que se reactualiza y se intensifica cada vez más. Y que se resiste. Esa resistencia a las formas de despojo y a las diversas formas de explotación se puede rastrear a lo largo de todo el continente y del mundo. En este dossier, cada uno de los textos nos ilustra sobre cómo se están llevando a cabo estos procesos en territorios y cuerpos concretos. 

Recuperamos la idea del caleidoscopio porque es un artefacto que permite crear diferentes figuras geométricas a partir del juego de colores, luces y sombras. Arroja imágenes en un momento determinado que luego desaparecen y reaparecen transformadas en la medida en que se utiliza. A partir de esta metáfora, pensamos al capitalismo como una totalidad simultáneamente constituida por relaciones económicas, políticas, sociales, culturales, ambientales, emocionales, subjetivas, que puede arrojar diferentes imágenes a partir de la rotación del “cilindro” teórico y metodológico, en función del momento histórico, de los cuerpos y del territorio.  Cada texto de este dossier puede pensarse en sí mismo como una propuesta para jugar con el caleidoscopio. En su conjunto, constituyen un aporte para los estudios feministas que, desde hace tiempo, hacen mover ese cilindro para ampliar la crítica clásica del marxismo al capitalismo, extender las fronteras para su aprehensión y, en consecuencia, ampliar los horizontes para su transformación.
Las luchas en el seno de la reproducción social
Authors: Varela Paula
Published: November 2023

En este artículo analizo la contradicción capital-vida en términos teóricos, para pensarla también en términos políticos. Para ello, en la primera parte despliego la perspectiva de la teoría de la reproducción social como mirada específica sobre esta contradicción; luego, describo brevemente ciertas características de las luchas por la reproducción de la vida desde abajo, como desafíos a los regímenes de reproducción social que imponen los Estados en el capitalismo; y, finalmente, propongo pensar la posición socio-reproductiva de las y los trabajadores de las instituciones de reproducción social —salud, educación, cuidados—, como fuente de poder de clase que permite poner sobre la mesa el derecho a establecer las condiciones de la reproducción de la vida.
Approaches to solving several definite integrals with special functions
Authors: Zhang Yingying
Published: November 2023

Calculus is the foundation of many natural sciences such as Physics. Calculus excels at calculating the area of irregularly shaped objects and thus it may be used in a vast array of domains. Because calculus is difficult to perform when combined with trigonometric and logarithmic functions, additional formulas are required to assist with calculations. By definition, limit of the sum of a function f(x) across given interval [a,b] is the definite integral. Notice the relationship between definite and indefinite integrals is as follow: result of a definite integral is a precise nice value, whereas an indefinite integral is expressed by a function. Their mathematical relationship is limited to computation regarding the Newton-Leibniz formula. This article describes only one of several methods for calculating definite integrals. Taylor expansion will also be used for auxiliary operations, while the relevant equations of Taylor expansion will also be presented in the text. It will also be learned through this paper that the result of the integral varies with .

Authors: Xu Anjie
Published: November 2023

Nowadays, the planning on manned mission to Mars from NASA and other institutions have brought interest to Mars again. People wonder if Mars can be the first colony of humanity. To provide an insight to this question, this essay focus on various prospective to discuss whether it is possible for humans to colonize Mars now, or perhaps in the near future. The essay first identifies essential technology needed for a success Mars colonization. Then, examine the past researches to check whether current technology can meet the requirements for Mars colonization. The research finds that the transportation between Earth and Mars is not hard to do, but the efficiency is extremely low by now. Building space stations as intermediates and developing recyclable rocket may help on this problem. When building a settlement on Mars, the life support system will not be a big issue because there are already functional technologies to produce oxygen and plant food on Mars, while water can be extracted from ice sheets on Mars. Meanwhile, requirement for energy can be easily solved by relying on solar energy, wind energy, geothermal energy and nuclear energy. Reconstructing Martian environment is not hard when it comes to altering the atmosphere, but is constructing an artificial magnetosphere is currently unpractical. Mars colonization is still not feasible now, but might be possible within one or two decades.

Black holes merger and the state-of-art detections
Authors: Chen Xingyu , Liu Yucheng , Zhang Ruining
Published: November 2023

Black hole mergers are fascinating astronomical phenomena that occur when two black holes gradually merge as they rotate and approach each other. This phenomenon is caused by explosive gravitational waves that propagate through space until they are detected. Black hole mergers are an extremely powerful origination as well as signature for GWs that can help us better understand the nature of the universe. Using the technology of VLBI, humans can construct the EHT and get access to the image of black holes. The EHT can resolve objects about 4000 times better than the Hubble Space Telescope thanks to this degree of precision, which enables people to perform more precise research on the exploration of the universe. At present, many research institutions around the world are involved, and a huge observation network has been established. Looking ahead, this paper finds that although humans have taken the first-ever photos of the apparent boundaries of black holes, there are still limitations to black hole detection. In future research, researchers will delve into black holes formation and evolution to reveal more about their mysteries. In addition, scientists should explore the interaction of black holes with other celestial bodies, which will help us to better understand galaxy creation and development and provide novel perspectives for the development of cosmology.
Analysis of application of FFT in quantum field
Authors: Xu Zhaoyang
Published: November 2023

The algorithm concept of fast Fourier transform, Heisenberg uncertainty, and the combination of the two are expounded. Fast Fourier Transform (FFT) is not a new discrete Fourier Transform, but a fast algorithm for Discrete Fourier Transform (DFT). For a long time, the DFT was not really used because of the large amount of computation, even if it was used by computers, it was difficult to deal with problems in real time. It was not until when Cooley and Key first proposed a fast algorithm for DFT operations, and later, when fast algorithms by G. Sullivan and. Key appeared in succession, that fundamental changes took place. People began to realize some inherent laws of DFT operation, and thus quickly developed and improved a set of high-speed and effective operation methods, which is now commonly known as the fast Fourier transform FF11 algorithm. Specifically, the position of a particle and its momentum cannot be determined simultaneously in a quantum mechanical system. It focuses on the proof and application of the Heisenberg inequality by TTF. Due to the different ways and methods of practical application, the practical significance and practical value of the application are for readers' reference. Besides, the space is limited and my knowledge is limited. Finally, the development direction of FFT in quantum physics is summarized.
