Authors: Bolzan Érica , Côco Valdete , Mello André da Silva 
Published: December 2024

O presente ensaio aborda perspectivas de currículos antirracistas no contexto da Educação Infantil tendo as danças populares como meio para a materialização de suas ações. Em diálogo com autores e autoras que discutem currículos, epistemologias e perspectivas decoloniais, objetiva reunir reflexões sobre arranjos curriculares outros, que contemplem as diversidades e as diferenças culturais por meio das danças populares afro-brasileiras, que historicamente têm sido silenciadas ou tratadas de maneira caricata e superficial nas instituições escolares. Em termos metodológicos, foram selecionadas referências para interlocuções que abarcam a perspectiva de ancoragem (estudos decoloniais), os tópicos articulados (currículo, práticas antirracistas e danças), as bases legais vinculadas (no caso, ao ensino da história e da cultura afro-brasileira) e dados contextuais, no horizonte de combinar descrição, análises e proposições na composição de reflexões situadas no campo da Educação Infantil. Conclui que o investimento na formação de professoras e professores é crucial no apoio ao trabalho pedagógico com as danças populares, na ampliação da visão de currículos e na educação antirracista.

Published: December 2024

O artigo debate acerca da leitura e da produção textual com adolescentes em escola de Ensino Fundamental do município de Serra/ES, em 2022. O campo problemático busca compreender como os agenciamentos produzidos pelo desejo desses praticantespensantes os impulsionam à leitura e à produção de textos. A metodologia de pesquisa-intervenção pauta-se na cartografia (Deleuze; Guattari, 1995) e nas conversas (Bondía Larrosa, 2003). Problematiza os diálogos entre estudantes de 9º ano e uma professora de língua portuguesa, realizando conexões com a noção de texto como produção de desejo (Larrauri, 2009) e agenciamento coletivo de enunciação (Deleuze; Parnet, 1998) no cotidiano escolar. Como resultados, destaca que os estudantes desejam escrever, mas há pouco interesse de expressarem-se com outras linguagens comunicacionais. Aponta os excessivos cuidados e tempos despendidos com a gramática, em detrimento de outras possibilidades de produção textual, outras semióticas menos estruturantes e mais encarnadas na vida dos sujeitos. Propõe investimentos em equipamentos, infraestrutura e qualificação para a produção dos textos em linguagens virtuais, estruturação das bibliotecas escolares e ampliação do número de estudantes leitores/escritores nas escolas.

Published: December 2024

O caráter prescritivo da Base Nacional Comum Curricular – Ensino Médio (BNCC-EM) e as determinações do Programa de Apoio à Implementação da Base Nacional Comum Curricular (ProBNCC) resultaram na construção da Proposta Curricular para o Ensino Médio da Paraíba (PCEM/PB), documento que materializou, em nível estadual, as transformações estabelecidas para os currículos do ensino médio no Brasil pela Lei nº 13.415 de 2017 e pela BNCC-EM de 2018. Impulsionados pelo questionamento sobre os limites do autodeclarado caráter participativo e democrático do seu processo de construção, o artigo ora apresentado tem por objetivo analisar a atuação do ProBNCC, bem como as estratégias utilizadas na Proposta Curricular da Paraíba, e como estas se alinham à BNCC-EM. A pesquisa documental utilizou as seguintes fontes: Portarias MEC nº 331/2018, nº 268/ 2018, nº 757/ 2019, e o Documento Orientador do ProBNCC 2019. A análise está alicerçada nos estudos de Sacristán (2000), Goodson (2007), Soares (2023) e Oliveira (2017). Os resultados levantados apontam que as ações e iniciativas articuladas pelo ProBNCC impuseram condicionamentos ao trabalho da comissão estadual, assim, estabelecendo orientação e/ou prescrição, procedimentos e estratégias de atuação. Nesta perspectiva, conclui-se que o regime de colaboração, instituído pelo ProBNCC, fortaleceu as posições do MEC em detrimento à autonomia dos estados, acentuando assimetria entre os entes federados na produção/formulação de políticas educacionais.
Ground-Motion Modeling Using MyShake Smartphone Peak Acceleration Data

Published: December 2024

ABSTRACT
In the field of ground-motion modeling, the availability of densely sampled ground-motion data is becoming key to mapping repeatable source, path, and site effects to enable ground-motion models (GMMs) to more accurately predict shaking from future earthquakes. This is particularly important because the field is moving toward nonergodic GMMs with spatially variable coefficients. To achieve the level of sampling required, the addition of non-instrumental data collected at very high spatial resolution, like felt intensity data or smartphone data, could prove essential. The predictive power of this nontraditional data for free-field ground motion needs to be tested before these data are used. In this work, we present a new database of over 1600 ground-shaking waveforms collected between 2019 and 2023 by the MyShake smartphone app, which delivers earthquake early warning messages to users on the U.S. West Coast. We develop a GMM, MyShake GMM, for peak smartphone-recorded accelerations in 3≤M≤5.5 earthquakes recorded at short (&lt;50 km) distances. We compare our model with free-field GMMs and show a similar geometric decay and a close match in predicted amplitudes for short-period spectral accelerations (SAs). We use residual correlation analysis to show that MyShake GMM residuals have a positive correlation with free-field residuals, with correlation coefficients of around 0.4 for peak ground acceleration, velocity, and short-period SA, similar to correlations previously reported between felt intensity and free-field data. This illustrates the potential that densely sampled smartphone ground-shaking data has in identifying repeatable free-field ground-motion effects for various ground-motion modeling applications. These could potentially include highly location-specific assessments of site response, ground-motion interpolation schemes like ShakeMap, or validating outputs from nonergodic, spatially variable coefficient GMMs.

Published: December 2024

Introduction: Soft tissue sarcomas (STS) of the distal extremities are a rare heterogeneous group of malignant mesenchymal tissue tumors, and the publications are extremely limited. They require a special approach because of their small size and functional significance of the areas in which they are located.The aim of our research was to analyze the clinical and morphological characteristics of hand and foot soft tissue sarcomas and to evaluate the results of treatment depending on various factors.Materials and methods: We conducted a retrospective analysis of clinical observations of 50 patients with hand and foot soft tissue sarcomas who were examined and treated from 2004 to 2023 at the Moscow Oncology Hospital № 62.Results: 50 patients with soft tissue sarcomas of the hand and foot were included in this study. There were 24 men and 26 women with a mean age of 45 years. Of the 50 sarcomas, 12 were localized on the hands and 36-on the feet. The commonest subtypes were epithelioid sarcoma in the hand and synovial sarcoma in the foot. The 5-year overall survival (OS) was 55.9%. There were no significant differences in OS or progression-free survival (PFS) among patients treated at a general hospital. 5-year OS in the group of the phalanx sarcoma was significantly higher (p = 0.025). Phalanx sarcomas were more often 5 cm or smaller in size (p = 0.007), but larger tumor size (> 5 cm) was not associated with lower survival. OS significantly decreased in proportion to increasing stage.Conclusion: Most hand and foot soft tissue sarcomas were less than 5 cm in size, which is indicating that it should not be used as a diagnostic threshold in the distal extremity region. Five-year OS in patients with soft tissue sarcomas of the phalanges is higher than in patients with sarcomas of more proximal localizations.

Objective: to evaluate the efficacy of first-line systemic therapy administered in real clinical practice to patients >75 years old with prostate cancer (PCa).Material: the retrospective study included data from 315 patients >75 years old (median age — 84 (75-99) years) with hormone-sensitive PCa (HSPCa) who received antitumor therapy. Non-metastatic HSPCa (nmHSPCa) was observed in 223 (70,8%) patients, while metastatic HSPCa (mHSPCa) — in 92 (29,2%) patients. In 8 (3,6%) cases of nmHSPCa, bicalutamide monotherapy was prescribed, while androgen deprivation therapy (ADT) was administered in 215 (96,4%) cases (intermittently — 164 (73,5%)). All 92 patients with mHSPC received ADT, including in combinations corresponding to current clinical recommendations — in 38 (41,3 %) cases (with docetaxel — 17 (18,4 %), abiraterone acetate — 7 (7,6 %), enzalutamide — 10 (10,9 %), apalutamide — 1 (1,1 %)). The median follow-up time for patients with nmHSPC was 64,2 (2,1-275,7) months, for patients with mHSPC — 48,6 (1,0-234,3) months.Results: the median duration of the 1st line of therapy for nmHSPC was 40,6 (1,0-243,8) months. In nmHPRPC, PSA reduction by>90% during the first line of therapy was seen in 67,3 % of patients. Five-year survival of patients with nmHPRPC without PSA progression (PFPS) reached 70,8%, progression-free survival (PFS) — 70,8%, metastasis-free survival (MFS) — 85,0%, specific survival (SS) — 97,3% and overall (OS) — 91,5%. Continuous ADT in lowand intermediate-risk nmHPRPC reduced PFS compared to intermittent therapy (p = 0.014), but did not affect MFS, SS and OS. The median duration of the first line of therapy for mHPRPC was 14,3 (1,1-137,7) months. In mHSPC, the frequency of PSA decrease by>90% during the first line of therapy was 38,0%. In patients with mHSPC, the 4-year PFSSA was 50,1%, DFS — 50,1%, DFS — 83,5% and OS — 77,2%. In mHSPC, ADT compared with combination therapy reduced DFS (p = 0.018), DFS (p = 0.053) and OS (odds ratio 3.675 (95% confidence intervals: 1.001-13.489); p = 0.008). No significant effect of the combination drug on the survival of patients with mHSPC was found.Conclusions: in elderly patients with nmHSPC, intermittent ADT is not inferior to continuous ADT in terms of OS. In patients > 75 years old, combination therapy based on ADT with docetaxel or androgen signal inhibitors provides an increased OS compared to ADT alone.

Introduction: Recent studies of neoadjuvant therapy for colon cancer indicate a significant percentage of patients’ retreatment, more likely due to the low accuracy of radiation diagnostics. The new Node-RADS lymph node assessment system can allow for more accurate selection of patients for neoadjuvant chemotherapy. Currently, the efficiency of adjuvant chemotherapy has been reliably substantiated for N1 within three months, for N2 within 6 months, for NO-only in the presence of negative prognosis factors. This allows us to study the applicability of neoadjuvant chemotherapy with high reliability of lymph node involvement according to computed tomography data in the preoperative period.Study objective: To determine the diagnostic efficiency of the Node-RADS system for predicting the risk of metastatic lymph node involvement in colon cancer patients.Materials and methods: A retrospective comparative analysis of computed tomography and pathomorphological examination data was performed for 75 colon cancer patients operated on at the M. N. A. S. Loginov in the period from 2021 to 2023. The clinical stage was routinely established based on the results of computed tomography of the chest and abdomen with intravenous contrast. Restaging was performed in the same patients according to the Node-RADS system with a lymph node score of 1-5 points. The results of two radiation diagnostic methods were compared with the data of the pathomorphological examination of the surgical material.Results: The accuracy (AUC) of computed tomography in the routine diagnostic method was 0.69. According to Node-RADS assessment, lymph nodes of 4-5 points were considered involved. Statistical analysis showed that the accuracy of this method increased significantly (AUC0.93). To determine the differences between the results of routine assessment, Node-RADS and the pathomorphological examination results, we found statistically significant (p < 0.0001) differences between the routine assessment and the results of pathomorphology, which corresponded to a low diagnostic value. At the same time, when comparing the results of the assessment according to Node-RADS and the conclusion of the pathomorphological study, no statistically significant differences were found (p = 0.109), which corresponded to sufficient diagnostic value of assessing the metastatic regional lymph nodes according to the Node-RADS criteria.Conclusions: The Node-RADS system, presented as a universal system for assessing malignant lymph nodes shows a fairly high diagnostic potential.

Cloud-edge-end based key management for decentralized applications
Authors: Zhang Jie , Zhang Futai 
Published: December 2024

How to securely manage and use private keys of digital signature schemes is a pivotal problem for blockchain-based decentralized applications (DApps), as they determine the ownership of data contents and digital assets. A well-recognized approach for key management is threshold cryptography which distributes private keys to different nodes such that the whole system can tolerate a certain number of failures or corruptions. Motivated by the key management need of DApps, threshold signature has attracted widespread attention, with a number of new constructions being proposed in recent years. However, a practical one for DApps' end users is still lacking, as existing schemes are hard to deploy due to the high cost of communication and distributed features.
In this paper, we combine $$ (2, 3) $$ -threshold signature with the widely deployed cloud-edge-end (CEE) paradigm. We first propose the CEE key management framework which involves an end node, an edge node and a cloud node maintaining $$ (2, 3) $$ shares of end users' private keys. Then, following the framework, we construct a $$ (2, 3) $$ -threshold elliptic curve digital signature algorithm (ECDSA) scheme with provable security based on the ECDSA assumption. Compared with representative constructions of generalized threshold ECDSA, the new scheme is easy to deploy in applications developed following the CEE framework. Additionally, it addresses share tampering and requires only three messages for distributively issuing a signature, which is lower than the best practice of $$ (2, 2) $$ -threshold ECDSA (four messages) that cannot tolerate tampering.

Published: December 2024

This paper examines the role of digital economy tools, including big data, mobile applications, e-commerce, and sharing economy platforms, in the sustainable development of tourism sector. The focus is on studying how the digital economy tools can contribute to more efficient and sustainable tourism services, to the service quality improvement, to reducing the negative environmental impact, and thus increase the availability of tourism resources in local destinations. On the example of successful use of digital technologies in Russian regions, the paper discusses the introduction of online platforms for booking services, the use of mobile applications for navigation and obtaining information about tourist sites, as well as the use of digital tools for predicting consumer preferences. Systematic approach to the analysis of tourism services digitalization, based on a set of technical and functional-digital indicators, allowed us to evaluate the impact of the digitalization level on the local destination sustainable development in the transition economy conditions. The proposed methodology for assessing and applying tourism services digitalization tools in Russian regions takes in account the transition economy specifics, and aims to promote more sustainable practices. The study will add to the existing literature by defining both technical and functional criteria for the implementation of digital technologies as tools for new business models creation in tourism, and development of tourism services digitalization model, based on assessment of regional digitalization level, to ensure the movement towards achieving sustainable development goals in local destinations.

Abstract

Topological materials, such as topological insulators or semimetals, usually not only reveal the
nontrivial properties of their electronic wavefunctions through the appearance of stable boundary
modes, but also through very specific electromagnetic responses. The anisotropic longitudinal magnetoresistance of Weyl semimetals, for instance, carries the signature of the chiral anomaly of Weyl fermions. However for topological nodal line (TNL) semimetals – materials where the valence and conduction bands cross each other on one-dimensional curves in the three-dimensional Brillouin zone – such a characteristic has been lacking. Here we report the discovery of a peculiar charge transport effect generated by TNLs: a dissipationless transverse signal in the presence of coplanar electric and magnetic fields, which originates from a Zeeman induced conversion of TNLs into Weyl nodes under infinitesimally small magnetic fields. We evidence this dissipationless topological response in trigonal PtBi2 persisting up to room temperature, and unveil the extensive TNLs in the band structure of this non-magnetic material. These findings provide a new pathway to engineer Weyl
nodes by arbitrary small magnetic fields and reveal that bulk topological nodal lines can exhibit
non-dissipative transport properties.
A Fully Coupled Viscoelastic Continuum Damage Model for Asphalt Concrete
Authors: Navjot Valappol , Narayan Srinivasa Parthasarathy Atul 
Published: December 2024

Abstract

Capturing the fatigue-induced evolution of viscoelastic properties of the material is crucial for predicting the fatigue life of asphalt concrete pavements. Current prediction models are often regression-based and lack accuracy, necessitating the adoption of mechanistic models like the Viscoelastic-Continuum Damage (VECD) models. The VECD models often rely on Schapery's work potential theory and elastic-viscoelastic correspondence principles, using pseudo-strain to separate viscoelasticity from damage mechanics. However, this decoupling imposes constraints on how viscoelastic properties can evolve. This study presents a new VECD model that fully couples the viscoelasticity of the material with its damage characteristics. It was developed within a Helmholtz-potential-based thermodynamic framework, ensuring consistency with the laws of thermodynamics. The model could describe the evolution of both the apparent storage modulus and loss modulus during fatigue tests over a wide range of strain levels. It captures the three-stage fatigue behavior of asphalt concrete, allows for unconstrained variations in the apparent phase angle, and provides a clear point of failure. Moreover, it can capture the variation of fatigue life with the applied strain level in a manner similar to the Asphalt Institute fatigue life model.
