Published: November 2022

The distribution characteristics and causes of casing deformation during hydraulic fracturing were investigated. Finite element models of a casing–cement sheath-formation assembly, considering a multi-stage fracturing process, were established. The axial displacement law of formation during multi-stage fracturing was analyzed. Furthermore, considering the existence of faults, the mechanism of casing deformation caused by fault slippage due to axial displacement was analyzed. Finally, the influence of fault parameters, as well as the casing’s geometry and mechanical parameters, on casing deformation were clarified. The results show that the casing deformation point is densely located near landing point A and sparsely located near toe point C. The entry of high-pressure fracturing fluid into the formation would reduce the effective stress of the formation and could even change it from compression to tension, which would mean that the formation in the fractured section would be stretched in the axial direction, squeezing the formation in the non-fractured area and causing axial displacement; the closer the formation is to point A, the greater the displacement. The change in casing deformation can be divided into three stages. In the first, the casing deformation is zero when the fracturing section is far from the fault. In the second, the casing deformation increases significantly when the fracturing section is close to the fault. In the third, the casing deformation increases slowly when the fracturing section deviates from the fault. The closer the fault is to landing point A, the greater the length, the smaller the dip angle, and the larger the casing deformation, and vice versa. In contrast, increasing casing wall thickness and steel grade has little effect on relieving the casing deformation.

Published: November 2022

Carbon and nitrogen are the essential elements constituting living organisms and are closely coupled during biogeochemical cycles. Due to the atmospheric nitrogen deposition and increased agricultural nitrogen fertilizer input, the effect of nitrogen on the sequestration of soil organic carbon (SOC) is controversial. To facilitate a comprehensive understanding of this issue, the progress of recent studies on the different SOC stabilization mechanisms is reviewed. Based on the differences in the stability and fate mechanisms of particulate organic carbon (POC) and mineral-associated organic carbon (MAOC), nitrogen input can increase POC input and inhibit microbial decomposition of POC by increasing terrestrial biomass, changing the quality of litter and promoting the formation of aggregates. N input reduces the chemical stability of MAOC by altering the chemical bonding of mineral–organic complexes. This study has promising implications for understanding the effect of N on SOC transformation by different stabilization mechanisms to promote soil carbon sequestration.

The NK-1 Receptor Signaling: Distribution and Functional Relevance in the Eye
Authors: Demirsoy Ibrahim Halil , Ferrari Giulio
Published: November 2022

Neurokinin-1 receptor (NK1R) signaling pathways play a crucial role in a number of biological processes in the eye. Specifically, in the ocular surface, their activity modulates epithelial integrity, inflammation, and generation of pain, while they have a role in visual processing in the retina. The NK1R is broadly expressed in the eye, in both ocular and non-ocular cells, such as leukocytes and neurons. In this review, we will discuss the roles of neurokinin-1 receptors and substance P (SP) in the physiopathology of eye disorders. Finally, we will review and highlight the therapeutic benefits of NK1R antagonists in the treatment of ocular diseases.
Is Violence Critique?
Authors: Williams Ryan
Published: November 2022

The offence and violence surrounding episodes like the Salman Rushdie Affair and the Danish cartoon controversies have furnished Western critique of Islam. While important work has challenged this criticism of Islam by interrogating the secular foundations of critique, the relationship between violence and critique remains troubling. Through reflecting on an excerpt from an attempted murder trial following an attack in purported retaliation for offending Islam in an English prison, this article considers an expanded notion of violence that recognizes the structural conditions behind violence and the political stakes that prioritize the psychological and ideological drivers that service criticism of Islam. This article builds on scholarship that explored the State and the violent actions of non-State actors and the critical studies of hate crimes, Islamist extremism, and radicalization to reflect on the role of critique in the aftermath of violence and to ask: “Is violence critique?” It argues for an approach to violence-as-critique by recognizing how emotion and violence are not merely resident inside the fanatical body that protrudes outwards but are instead part of the wider, circulating, and unstable affective economies of structural violence where violences can be mutually reinforcing.
Identification of Geodiversity and Geosite Assessment around Geohazard Area of Suoh Aspiring Geopark in West Lampung, Sumatra, Indonesia

Published: November 2022

Indonesia has been actively promoting the Sustainable Development Goals (SDGs) agreed upon at the United Nations General Assembly in 2015. Pursuing economic expansion through extraction of natural resources is an obsolete paradigm that is becoming increasingly outdated. Therefore, the geopark concept has broken the idea of economic progress that damages the environment. Geoparks seek to safeguard geodiversity, educate the public about geological history, and assist the long-term economic growth of geopark areas, particularly through geotourism. Geotourism is a sort of creative tourism that is fast growing across the world. This paper aims to assess the existing status and geotourism potential in order to identify the best geosites for the West Lampung region’s initial geopark development. The methods of this study are a geology and geopark literature review, fieldwork, data analysis, and synthesis. The procedure includes inventorying and identifying geodiversity. The study looked at rock and outcrops to piece together the geological history of the West Lampung region. This study showed that the West Lampung region offers several remarkable geosites with significant geotourism development potential. Asam Lake, Nirwana Crater, and Point View Suoh Valley in the Suoh part have the greatest final values, followed by Batubrak Fault Depression in the Fault Depression section. The Batubrak Fault Depression and Asam Lake have significant scientific and tourist value, particularly in terms of portrayal, uniqueness, perspectives, scenery, and natural surroundings. In the Suoh section, Nirwana Crater, Kopi Susu Crater, Keramikan Crater, and Point View Suoh Valley have significant scientific importance but poor educational and tourism value, while the other sites have low scientific, tourist, and educational value, thus placing the area at the bottom of the assessment even though overall it is of medium value. It can be concluded that several geosites in West Lampung have poor value due to some factors such as location accessibility, tourism infrastructure, and location management. Looking at the total findings, basic tourism infrastructure, visitor center, and tour guide services, as well as promotional efforts, are important factors in attracting more tourists to the West Lampung geosites.
The Elderly’s Thoughts and Attitudes about Polypharmacy and Deprescribing: A Qualitative Pilot Study in Portugal

Published: November 2022

The high prevalence of polypharmacy and potentially inappropriate medications in the elderly makes them a vulnerable group to adverse drug events. Deprescribing is the medication review plus cessation of potentially inappropriate medications with a health professional’s help. Several barriers and enablers influence it, and its knowledge can help health professionals. The objective of the study is to understand the Portuguese elderly’s attitudes and ideas about polypharmacy and deprescription. We made a qualitative approach through a focus group with elderly patients from an adult daycare center with transcription and codification into themes and subthemes based on previous frameworks. Eleven elderly patients participated in the focus group. The identified elderly’s ideas and attitudes could be clustered into five main barriers: appropriateness, process, influences, fear, and habit, and five main enablers: appropriateness, process, influences, dislike, and cost. Although the elderly’s strong beliefs regarding medication benefits and necessity prevail, contrary opinions regarding lack of benefit/necessity, drug interaction/side effects, and medication complexity/number may influence their willingness to deprescribe positively. The health professional’s influence and the patient’s trust in their doctors were perceived essential for decision-making as either a barrier or an enabler. The medication benefit was a big barrier, and side effects/drug interaction experiences are an important enabler.
Air Pollution, Climate Change and Ecosystem Health in the Niger Delta

Published: November 2022

There are interactions and feedbacks between air pollution as a driver of environmental change, climate change, and overall ecosystem health. Air pollution is a major environmental problem, particularly in developing countries where regulations may be lax. This paper explores the nexus between air pollution, climate change and overall ecosystem health in the Niger Delta region of Nigeria. It brings novelty by exploring these issues with an environmental justice lens. This is particularly pertinent due to the ecological sensitiveness of the region and the high dependence of the indigenes on the land and water. The region’s ecosystem is becoming more and more threatened as pollution increases and the climate changes further. Nigeria’s position as the largest oil producer in Africa and the sixth largest in the world is due to the oil and gas reserves of its Niger Delta region. The irony becomes that while the region is the mainstay of the Nigerian economy or is a source of national ‘good’, they have received in return only environmental ‘bads’. The many levels of deprivation experienced by the indigenes of the Niger Delta is a classic case of environmental injustice where the region disproportionately bears a much higher burden of air, land, and water pollution in comparison to other parts of the country. Gas flaring, fossil fuel burning, artisanal refining of crude, and transportation are found to be the main sources of air pollution in the locality. Mitigating air pollution and the attendant impacts requires urgent action and concerted effort at the individual, local and national levels. This paper provides recommendations in this regard.
A Hybrid Hesitant Fuzzy Model for Healthcare Systems Ranking of European Countries
Authors: Aktas Ahmet , Ecer Billur , Kabak Mehmet
Published: November 2022

Ranking several countries on a specific area may require the consideration of various factors simultaneously. To obtain a ranking of countries, the development of analytical approaches, which can aggregate opinions of a group of people on various criteria, is essential. The main aim of this study was to propose such a ranking approach for European countries in terms of healthcare services. To this end, a hybrid group decision-making model based on Hesitant Fuzzy Linguistic Terms Set (HFLTS) and Hesitant Fuzzy Technique of Order Preference by Similarity to Ideal Solution (HF-TOPSIS) is presented in this study. Importance degree of indicators were determined by the HFLTS-based group decision-making approach, and then HF-TOPSIS was used to obtain the rank of countries. According to the results obtained by the proposed model, Austria, Sweden and Finland are the best European countries in terms of healthcare services. Moreover, two comparative analyses, one for the utilization of different hesitant fuzzy distance measures in HF-TOPSIS and one for the ranking of countries obtained by utilizing TOPSIS, return some variations in country rankings. While Austria remained the best country for all distance measures in the hesitant fuzzy environment, Luxemburg was found to be the best for the deterministic case of TOPSIS.

Polyhexamethylene guanidine phosphate (PHMG-p), the main ingredient of humidifier disinfectants, circulates systemically through the lungs; however, its toxicological assessment has been primarily limited to pulmonary disease. Herein, we investigated the possible abnormalities in hematopoietic function 20 weeks after intratracheal instillation of PHMG-p in a rat model. Notable abnormalities were found out in the peripheral blood cell count and bone marrow (BM) biopsy, while RNA sequencing of BM tissue revealed markedly altered gene expression. Furthermore, signaling involved in hematopoietic dysfunction was predicted by analyzing candidate genes through Ingenuity Pathway Analysis (IPA) program. Respiratory PHMG-p exposure significantly decreased monocyte and platelet (PLT) counts and total protein, while significantly increasing hemoglobin and hematocrit levels in peripheral blood. Histopathological analysis of the BM revealed a reduced number of megakaryocytes, with no significant differences in spleen and liver weight to body weight. Moreover, PHMG-p exposure significantly activated estrogen receptor signaling and RHOA signaling, and inhibited RHOGDI signaling. In IPA analysis, candidate genes were found to be strongly related to ‘hematological system development and function’ and ‘hematological disease.’ Accordingly, our results suggest that PHMG-p could affect hematopoiesis, which participates in monocyte differentiation and PLT production, and may induce hematologic diseases via the respiratory tract.

O caldeirão da bruxa: a magia e o sincretismo religioso na Wicca
Authors:   , Silva Dartagnan Abdias
Published: November 2022

A Wicca é uma religião criada no seio da modernidade, no século XX. Sua crescente popularização chama atenção na tentativa de compreender suas relações com a modernidade e a estruturação de sua resposta e agenda contracultural. A presente tese visa alçar compreensões, ensaios e reflexões mais profundas da relação da Wicca com as críticas contramodernas da atualidade. Desse modo, a Wicca aqui é entendida como uma instituição intermediária, capaz de desempenhar um papel de mediação entre o religioso e o social, aqui entendido na privatização religiosa, e, portanto, uma mediação entre os sentidos e valores individuais e o coletivo plural da modernidade. Os ensejos de uma afirmação enquanto religião consolidada da Wicca a conduz em importantes revisões de sua prática e adaptabilidade no mundo moderno, fazendo com que, da assertividade de suas respostas, dependa suas relações mais amplas com o cenário e o circuito em que está inserida nos meios pagãos e na Bruxaria Moderna. Através da pesquisa de campo em um coven wiccano em São Paulo/SP e em fóruns virtuais e pautada na observação participante assumida numa postura subjetivada de mediação entre o pesquisador e o interlocutor, conjuntamente com a revisão bibliográfica acadêmica e nativa, a presente tese apresentará articulações de como essa relação se dá, trabalhando a relação entre Wicca e modernidade a partir tanto de sua estrutura religiosa, institucional, do estudo de uma liderança local e da articulação de seus participantes. Desse modo, é possível alçar voos em direção à compreensão tanto das agendas absorvidas pela Wicca, quanto de sua inserção nas lutas contra hegemônicas da modernidade. Permeando essa compreensão, poderemos também entender como a Wicca responde à “crise de sentido da modernidade” apontada por Berger e Luckmann (2012) e como essa resposta pode ser mais bem adequada a partir das críticas internas erigidas à “Religião das Bruxas”.
Contribuição do planejamento do trabalho educativo para o alcance dos objetivos da ação pedagógica na educação física escolar
Authors:   , Oliveira Moacyr dos Santos
Published: November 2022

A presente tese é motivada pela defesa do planejamento do trabalho educativo como atividade essencial para as ações pedagógicas na educação física escolar. O estímulo deste estudo é o problema da necessidade de se conhecer a estrutura geral do planejamento e como o seu conhecimento possibilita aos professores sustentação para o cumprimento dos objetivos da ação pedagógica na educação física. O referido problema advém da constatação de que o planejamento tem sido relegado pelos docentes de educação física, em virtude dos seguintes fatores: sua redução ao cumprimento de demandas burocráticas; visão como sendo tarefa apenas para o início do ano letivo; falta de embasamento teórico para sua elaboração; concepção de que a experiência o substitui, entre outros. Logo, o objetivo geral desta pesquisa é analisar como o planejamento do trabalho educativo contribui para o alcance dos objetivos da ação pedagógica na educação física escolar. Para se chegar a ele, delineiam-se os seguintes objetivos específicos: discutir a necessidade de superar a relação do planejamento educacional com os interesses do capital na formação social brasileira; analisar o que é o conceito de planejamento e sua ligação com as dimensões políticas, sociais e culturais da escola, bem como suas implicações para a educação física; analisar o processo psíquico que envolve a ação de planejar; investigar como o planejamento vem sendo abordado na educação física. Para a consecução desses propósitos, serão realizados uma pesquisa bibliográfica e o estudo do estado da arte da temática do planejamento em seu nexo com a educação física. Parte-se dos pressupostos de que a categoria trabalho é atividade fundante do ser social, do materialismo histórico-dialético como método de análise da realidade concreta, da pedagogia histórico-crítica como concepção pedagógica, da psicologia histórico-cultural em sua relação com a concepção pedagógica e da abordagem crítico-superadora na educação física por defender a transmissão da cultura corporal como conhecimento. Os resultados da pesquisa possibilitaram a defesa da tese ao revelar que o planejamento da atividade pedagógica é um processo de significações captadas pelo indivíduo, a partir da translação dos objetivos refletidos na consciência. Consequentemente, são estabelecidas as ações e as operações voluntárias direcionadas à consecução de finalidades educacionais. Assim, o planejamento, ao condensar o conteúdo, a forma e o destinatário da atividade, contribui para a educação física ao conferir a consciência e a intencionalidade das atividades da cultura corporal orientadas para a formação do pensamento por conceitos e dos comportamentos complexos
Arquitetura híbrida para a previsão de afluências em reservatórios baseada no modelo SMAP e Deep Learning
Authors:   , Maciel Guilherme Marins
Published: November 2022

Modelos hidrológicos são ferramentas essenciais para prever ou gerar cenários da disponibilidade de recursos hídricos, usados para planejar a operação de sistemas elétricos de curto a longo prazo. No entanto, há um empasse ao escolher um determinado modelo. Modelos complexos, como modelos distribuídos, podem fornecer bons resultados por procedimentos analíticos, otimizações robustas e dados sofisticados. Já modelos mais simples, como os concentrados, oferecem resultados razoáveis com abordagens de ajuste muito mais fáceis. Para melhorar a qualidade de modelos mais simples, este trabalho propõe o acoplamento do modelo hidrológico Soil Moisture Accounting Procedure (SMAP) com uma arquitetura Deep Learning baseada em camadas Conv3D-LSTM. Na metodologia proposta, o SMAP é primeiramente otimizado para obter parâmetros gerais da bacia hidrográfica. Este modelo recebe um ajuste local, baseado no algoritmo Twiddle, usado como entrada para a arquitetura Conv3D-LSTM. Este modelo de estimativa de caixa cinza pode gerar resultados rápidos e precisos. Estudos, visando prever a vazão natural com sete dias de antecedência, foram realizados em duas grandes hidrelétricas brasileiras para validar o método. Os resultados obtidos pela arquitetura híbrida são melhores que os obtidos com as técnicas desacopladas.

A presente tese destina-se a desenvolver a batucada como noção, em uma perspectiva expandida. Nessa direção, a batucada enquanto forma de expressão e percurso investigativo do âmbito dos Estudos Literários. Portanto, a batucada, de maneira ampliada, como campo de vivências e movimentações do âmbito das mestrias, relacionada a mestres e mestras. Enfim, a mesma a ser compreendida como tecnologia e saber atrelado a aspectos históricos, sociais, econômicos e políticos. Interessa-nos, pois, reafirmar traços relativos à dimensão humana que tende a compor suas tramas e fios, a marcar e demarcar seus processos de adequações e readequações tecnológicas, principalmente, a partir do início do século XX. Entre a rigidez e o rigor, interessa compreender a batucada como linguagem cultural, ou seja, prática criativa, investigativa, pedagógica e lugar no qual se produz a escuta, ao mesmo tempo em que é produzida. Assim, a batucada, mais do que como sistema de comunicação de ideias ou sentimentos, mas como espécie de dialeto a disponibilizar sensações e expressividade. Desta forma, esta tese traz como objetivos gerais a possibilidade de contribuir para a democratização, a circulação e a difusão do acesso a bens culturais imateriais como a batucada, bem como intenciona poder interferir, de modo efetivo e equânime, na mediação de cada vez mais presenças de mestres e mestras genuínas de saberes e tecnologias autênticas, nos mais diferentes espaços da sociedade. Em termos específicos, este estudo busca ir ao encontro de articular pontos relativos ao que pode ser importante e necessário à revisão da própria batucada enquanto concepção em si mesma, a se encaminhar por mais possibilidades de apresentações do que propriamente representações ao entendimento de batucar. Dessa maneira, o caminho percorrido se deu no âmbito interdisciplinar, intertextual e a partir de revisão bibliográfica com recortes que se relacionam com textos conceituais e teóricos como filmes, músicas, danças, pinturas, poemas e histórias lidas, ouvidas e vistas, entre outras narrativas que contribuíram teoricamente ao trabalho. Nessa direção, por fim, visualizamos o pensamento na iminência de poder ser tecido como batucada e vice-versa, como meio de expressar e proceder.
Generation and uncertainty quantification of patient-specific purkinje network models
Authors:   , Berg Lucas Arantes
Published: November 2022

Cardiac Purkinje networks are a fundamental part of the conduction system and are known to initiate a variety of cardiac arrhythmias. However, patient-specific modeling of Purkinje networks remains challenging due to the high morphological complexity and the lack of non-invasive imaging techniques to identify these structures. This work aims to present a novel method called Shocker based on optimization principles for the generation and uncertainty quantification of patient-specific Purkinje networks that combine geometric and electrical accuracy in branch size, bifurcation angles, and Purkinje-Ventricular-Junction activation. Several Purkinje network models are generated over four different biventricular meshes with increasing complexity to reach this goal. They are used to evaluate the performance of our model in a range of different scenarios. Additional Purkinje-tissue coupled monodomain simulations are executed to evaluate the generated networks in a more realistic scenario using the most recent Purkinje/ventricular human cellular models, physiological values for the Purkinje-Ventricular-Junction characteristic delay, and a high-performance GPU solver. The results demonstrate that the new method can generate patient-specific Purkinje networks with controlled morphological metrics, local activation times at the Purkinje-Ventricular-Junctions, estimated points given by the patient electro-anatomical map and electrocardiogram. In addition, the generation of multiple Purkinje network models that can reproduce the same patient-specific data is an important tool for quantifying uncertainties associated with the computational modeling of this important conduction system of the human heart
O Vedāntasāra de Sadānanda (séc. XV): uma leitura hermenêutica sobre a doutrina do Advaita Vedānta
Authors:   , Silva Bruno do Carmo
Published: November 2022

A tradição da Escola Vedānta, cuja a matriz filosófica são os Upaniṣads, possui uma vertente hermenêutica radicalmente fundada na noção de não-dualidade, essa vertente não-dualista se expressa por meio da Escola Advaita Vedānta. A tradição da Escola Advaita Vedānta possui uma linhagem de sucessão discipular (guruśiṣyaparamparā) composta por grandes filósofos, dos quais se destacam Śaṅkarācārya e Sureśvarācārya, seu discípulo dileto. Esses dois filósofos se destacaram por suas realizações dentro da tradição Advaita Vedānta, principalmente no que tange à produção textual, tendo ambos produzido comentários (bhāṣyas) sobre os Upaniṣads e alguns trabalhos independentes (prakaraṇas). Nesse sentido, a tradição do Advaita Vedānta é, de tempos em tempos, atualizada com novos trabalhos sobre a sua doutrina. Um dos principais trabalhos já realizados sobre a doutrina do Advaita Vedānta é a obra Vedāntasāra, composta por Sadānanda, um renomado vedantino do século XV. O Vedāntasāra é, fundamentalmente, uma síntese da filosofia vedantina, principalmente no que se refere à sua vertente não-dualista (advaita). Sendo assim, aqui nesta tese, conheceremos a doutrina do Advaita Vedānta, i.e., a sua essência, por meio de uma leitura hermenêutica da obra Vedāntasāra.
Advances in hybrid power line/wireless systems
Authors:   , Filomeno Mateus de Lima
Published: November 2022

This dissertation investigates the hybrid power line/wireless system (HPWS), which consist of using power line and wireless media in parallel, to improve point-to-point data communication performance. In this context, the studied topics are: power allocation and subcarrier permutation in orthogonal frequency-division multiplexing schemes, as well as the application of orthogonal chirp-division multiplexing (OCDM) schemes into the HPWS. Throughout the dissertation, the simultaneous transmission of the same symbols through power line and wireless channels is considered so that maximal-ratio combining can be employed at the receiver. Regarding power allocation, the achievable data rate and average bit error probability are individually optimized under two and distinct transmission power constraints. Regardless of the power constraint, it is demonstrated that at most one medium must be used in the same subchannel index when the objective is to maximize the achievable data rate or to minimize the average bit error probability. Consequently, well-known solutions are adapted to provide power allocation algorithms that demand low computational costs. Numerical analyses validate the proposed algorithms, proving their optimality and superiority in relation to other algorithms of the literature. With respect to subcarrier permutation, its optimality is analyzed to either maximize the achievable data rate or minimize the average bit error probability, assuming the optimal or uniform power allocations. For all cases, it is shown that the subcarriers used in one medium must be sorted in ascending order of normalized signal-to-noise ratios (nSNRs) and then combined with the subcarriers used in the other medium sorted, in its turn, in descending order of nSNRs. Numerical results show that higher gains of this subcarrier permutation are obtained as frequency selectivity increases and that subcarrier permutation can be extremely useful for increasing the achievable data rate or decreasing the average bit error probability. Regarding the application of OCDM schemes into the HPWS, wide-sense stationary random processes in the discrete-Fresnel domain are studied so that the maximal-ratio combining technique can be derived. In addition, the optimal power allocation is analyzed. Numerical analyses then show that the OCDM-based HPWS may be a suitable choice if the aim is to minimize the bit error probability and the transmitter has partial (one bit of information) or no knowledge of the channel state. Finally, a pilot symbol that enables joint channel estimation and synchronization is derived for power line and wireless OCDM schemes. Numerical results based on measurements validate the proposed symbol

How to Build the “Optical Inverse” of a Multimode Fibre
Authors: Būtaitė Unė G. , Kupianskyi Hlib , Čižmár Tomáš , Phillips David B.
Published: November 2022

When light propagates through multimode optical fibres (MMFs), the spatial information it carries is scrambled. Wavefront shaping reverses this scrambling, typically one spatial mode at a time—enabling deployment of MMFs as ultrathin microendoscopes. Here, we go beyond sequential wavefront shaping by showing how to simultaneously unscramble all spatial modes emerging from an MMF in parallel. We introduce a passive multiple-scattering element—crafted through the process of inverse design—that is complementary to an MMF and undoes its optical effects. This “optical inverter” makes possible single-shot widefield imaging and super-resolution imaging through MMFs. Our design consists of a cascade of diffractive elements, and can be understood from the perspective of both multi-plane light conversion, and as a physically inspired diffractive neural network. This physical architecture outperforms state-of-the-art electronic neural networks tasked with unscrambling light, as it preserves the phase and coherence information of optical signals flowing through it. We show, in numerical simulations, how to efficiently sort and tune the relative phase of up to

~

400 step-index fibre modes, reforming incoherent images of scenes at arbitrary distances from the fibre facet. Our optical inverter can dynamically adapt to see through experimentally realistic flexible fibres—made possible by moulding optical memory effects into its design. The scheme is based on current fabrication technology so could be realised in the near future. Beyond imaging, these concepts open up a range of new avenues for optical multiplexing, communications, and computation in the realms of classical and quantum photonics.

Authors: Тимофеев Г.О. , Рощин А.Б.
Published: November 2022

Рассмотрены возможности алгоритмов машинного обучения для оценки устойчивости тестов CAPTCHA к автоматизированному распознаванию, а также различные усовершенствования этих тестов, которые снижают вероятность корректного распознавания изображений автоматизированными системами. С помощью сверточной нейросети ResNet-18 выполнены оценки эффективности распознавания и возможности применения предобученных моделей для распознавания новых объектов. После проведения анализа изображений были выявлены основные уязвимости, позволяющие автоматизи- рованным системам легко проходить тесты CAPTCHA. Для повышения устойчивости лексикографических тестов предложено использовать случайное и независимое изменение цветов в изначальном RGB-изображении для некоторых пикселей, которые входят в значащие символы. Эффективность таких изменений составила 11,8%.

Capabilities of machine learning algorithms for estimation of CAPTCHA tests resistance against automated recognition are considered. Various improvements of these tests, which reduce the probability of correct recognition by automated systems are also discussed. Using the ResNet-18 convolutional neural network, the recognition efficiency and the possibility of using pre-learned models for recognizing new objects are evaluated. After analyzing the images, the main vulnerabilities were identified that allow automated systems to easily manage CAPTCHA tests. To increase the stability of lexicographic tests, it is proposed to use a random and independent color variation in the original RGB image for some pixels that are included in meaningful characters. The effectiveness of these actions was 11.8%.
