Doubly resonant metal-free electro-optic microwave receiver in aluminum nitride
Authors: Lipkowitz Steven T. , Berk Warren P. , Grutter Karen E. , Murphy Thomas E. 
Published: April 2024

This paper demonstrates a passive, integrated electro-optic receiver for detection of free-space microwave radiation. Unlike a traditional microwave receiver, which relies on conductive antennas and electrical amplifiers, this receiver uses only passive, optically probed elements with no electrodes or electronic components. The receiver employs two co-resonant structures: a dielectric resonator antenna (DRA) to concentrate incoming microwave radiation and an integrated aluminum nitride (AlN) racetrack resonator to resonantly enhance the optical carrier. The microwave field of the DRA modulates the built-up optical carrier in the resonator via the electro-optic response of AlN. We successfully detected 15 GHz microwave radiation through co-resonant electro-optic up-conversion, without the need for any conducting electrodes, amplifiers, or electronic components.

Published: April 2024

A presente pesquisa teve por objetivo identificar e analisar as possibilidades e formas de mediação pedagógica nas práticas de professores/as de crianças da pré-escola da Rede Municipal de Educação de Catalão (GO). Fundamentadas pelos pressupostos da teoria Histórico-Cultural, parte-se da defesa da educação como condição universal do desenvolvimento humano e da mediação pedagógica como condição maior para o trabalho docente. Realizou-se uma pesquisa de campo em duas instituições municipais de Educação Infantil de Catalão (GO), utilizando-se dos procedimentos metodológicos: observações e entrevistas semiestruturadas. A análise dos dados foi realizada a partir do método marxista, com ênfase nas categorias: trabalho docente, práxis e mediação pedagógica. Os resultados apontam para a centralidade da categoria mediação pedagógica nas práticas docentes na pré-escola, ainda que sinalize uma ênfase nas práticas pedagógicas com vistas à formação da competência leitora e da preparação das crianças para o 1º ano do Ensino Fundamental. Observa-se, ainda, uma dicotomização entre as mediações pedagógicas oportunizadas na creche e na pré-escola, reforçando alguns dos binômios que historicamente assombram/instigam pesquisadores e professores da Educação Infantil. Defendemos a importância de superar a fragmentação dessa etapa e de garantir condições objetivas para a efetivação de mediação pedagógica qualificada e da tríade ensino/aprendizagem/desenvolvimento infantil.

O ensino-aprendizagem da escrita e da leitura exige o conhecimento e a prática de vertentes teóricas e metodológicas que apresentem ao professor de língua portuguesa caminhos possíveis para o trabalho com a língua/linguagem em sala de aula. Nesse cerne, o presente artigo parte de reflexões acerca do ensino da escrita e da leitura à luz de autores como Antunes (2003), Oliveira (2010), entre outros, que subsidiaram também a realização de uma experiência exitosa desenvolvida na disciplina de língua portuguesa, com alunos dos anos finais do ensino fundamental em consonância com os postulados da Base Nacional Comum Curricular – BNCC – (BRASIL, 2017) no contexto de ensino remoto, adotado pelas escolas em decorrência da pandemia ocasionada pela COVID-19. Desse modo, percebemos a necessidade de intensificação das metodologias do ensino da escrita e da leitura, principalmente no contexto de aulas não presenciais. Portanto, esperamos que a presente discussão e a experiência compartilhada neste trabalho agucem os estudos acerca do ensino de língua portuguesa na educação básica e proporcionem reflexões em torno de possíveis metodologias para a abordagem da escrita e da leitura por serem relevantes práticas de linguagem nos contextos de ensino presencial e remoto.
Europe in Literature
Authors: Franco Bernard 
Published: April 2024

Abstract
This article examines the origin of the idea of Europe and its identity in relation to literature. It attempts to show that, before being a cultural, economic or political reality, Europe was a literary concept, whose origins are closely linked to the literary theories of the Romantics, particularly the German Romantics. The links between the idea of Europe and literature also associate Europe with the birth of comparative literature. But at the same time, the notion of World Literature, even if it has a Eurocentric background in Goethe and his successors, calls for the poet to transcend Europe and become a citizen of the world.
A new look at the geodynamic development of the Ediacaran–early Cambrian forearc basalts of the Tannuola-Khamsara Island Arc (Central Asia, Russia): Conclusions from geological, geochemical, and Nd-isotope data
Authors: Mongush Andrey Alexandrovich , Olschewski Pascal 
Published: April 2024

Abstract
Oceanic igneous rocks throughout the Altai-Sayan Fold Belt (ASFB) in central-southern Siberia are often considered to be late Precambrian–early Paleozoic accreted elements of oceanic crust – often of uncertain paleogeographic or geodynamic origin. We explore the role of suprasubduction zone settings in the formation of different ASFB terranes. Our study offers a non-accretionary perspective on the tectonomagmatic development of basalt-bearing units in the ASFB on the example of the forearc terrane of the Ediacaran–early Cambrian Tannuola-Khamsara island arc (herein termed Sayan-Tuvan forearc zone). We describe the geochemistry, structural geology, and stratigraphic relations of basalts of the Aldynbulak, Uttug-Khaia, and Chingin formations, which are integral parts of the Sayan-Tuvan forearc zone. The Aldynbulak basalt samples mainly fall in the compositional fields of ocean island basalts and enriched mid-ocean ridge basalts (E-MORB) and likely derived from a deep mantle source. The Uttug-Khaia and Chingin basalts are N- and E + T-MORB-like basalts, carrying forearc geochemical signatures. Specifically, the Chingin Formation contains boninite dikes and is associated with a boninite-bearing ophiolite. Boninites are commonly associated with forearc magmatism and thus a forearc formation setting is likely. Tectonic and stratigraphic considerations imply that the Aldynbulak basalts formed first, followed by the Uttug-Khaia and later the Chingin basalts and boninites. A schematic model, involving decompression melting of the mantle, is proposed for the development of the studied forearc basalt suites that are linked with the growth of the Tannuola-Khamsara island arc system 580–540 million years ago.
Simulation of range code tracking loop for multipath mitigation in NavIC receiver
Authors: Rairala Naraiah Pedda , Perumalla NaveenKumar 
Published: April 2024

Abstract
The Operational Navigation with Indian Constellation (NavIC) comprises seven satellites in the orbit, including three in geostationary orbit (GEO) and four in geosynchronous orbit (GSO). NavIC provides both Standard Positioning Service and Restricted Service, using L5 (1176.45 MHz) and S1 (2492.028 MHz) frequencies, with coverage extending 1500 km around the mainland of India. In an urban canyon, multipath interference severely reduces the precision and reliability of NavIC positioning. Many current multipath mitigation techniques often exhibit high computational requirements or reliance on external assistance. In this paper, a ranging code tracking loop is proposed that can sustain either a late or early branch in contrast to the Narrow-Spacing (NS) correlation technique for mitigating multipath for NavIC receiver. The design of proposed code tracking loop is based on steepest descent algorithm. The findings demonstrate that, in terms of calculation time and code multipath mitigation, the suggested technique performs better than both Multipath Estimated Delay Locked Loop (MEDL) and NS correlation. The proposed method produces less than 0.016 chips for the tracking error Standard Deviation (STD). In addition, the recommended method takes 24 % less computation time.
Nonparametric estimation of conditional incremental effects
Authors: McClean Alec , Branson Zach , Kennedy Edward H. 
Published: April 2024

Abstract
Conditional effect estimation has great scientific and policy importance because interventions may impact subjects differently depending on their characteristics. Most research has focused on estimating the conditional average treatment effect (CATE). However, identification of the CATE requires that all subjects have a non-zero probability of receiving treatment, or positivity, which may be unrealistic in practice. Instead, we propose conditional effects based on incremental propensity score interventions, which are stochastic interventions where the odds of treatment are multiplied by some factor. These effects do not require positivity for identification and can be better suited for modeling scenarios in which people cannot be forced into treatment. We develop a projection approach and a flexible nonparametric estimator that can each estimate all the conditional effects we propose and derive model-agnostic error guarantees showing that both estimators satisfy a form of double robustness. Further, we propose a summary of treatment effect heterogeneity and a test for any effect heterogeneity based on the variance of a conditional derivative effect and derive a nonparametric estimator that also satisfies a form of double robustness. Finally, we demonstrate our estimators by analyzing the effect of intensive care unit admission on mortality using a dataset from the (SPOT)light study.
A typological approach to intersubjective uses of the Finnish clitic markers =hAn and =se from the perspectives of engagement and their interrelations with subject person
Authors: Yurayong Chingduang , Kittilä Seppo 
Published: April 2024

Abstract
The present study adopts a typological approach to investigate intersubjective uses of the Finnish clitic markers =hAn and =se, which are derived from third-person pronouns, within the emerging framework of engagement. The methods encompass two data gathering approaches: 1) a qualitative survey involving actual Finnish language users through a questionnaire to identify functions, and 2) a quantitative survey examining co-occurrences between the clitic markers and subject persons using the Suomi24 Sentences Corpus 2001–2020 for usage-based frequencies. The data analysis focuses on the interrelations with a subject person, drawing parallels with other languages which exhibit similar phenomena of pragmatic extension from referential uses towards engagement marking. The results reveal that the two Finnish clitics semantically inherit their referential meanings from their lexical forms and further extend them towards marking interlocutors’ intersubjectivity, enriching the engagement system of Finnish. A distinct difference related to the subject person becomes evident. On the one hand, =hAn as a recognitional marker more frequently co-occurs with first person, signalling the speaker’s involvement in epistemic management as a speech act participant responsible for managing inclusive attention and shared information with the hearer. On the other hand, =se as a contrastive marker co-occurs more frequently with third person in general and with second-person statements which involve the speaker’s observed information and its exclusivity.

Published: April 2024

Abstract
This study discusses the experimental results of the ballistic impact on thick-layered carbon fibre-reinforced polymer (CFRP), glass-based FRP (GFRP), and Kevlar-based FRP (KFRP) composite plates. Ten 10 mm plates of each type were manufactured via the hand lay-up and vacuum bagging techniques to produce plates with a thickness of 2 mm each, which were bonded together using epoxy adhesive and hot pressed at 75°C to obtain thick layered plates with a total thickness of 20 mm each. The specimen plates were tested according to the NIJ 0108.01 standard in a special firing room using a 9 mm G2 Elite handgun with a full metal jacketed round nose 9 mm × 19 mm Mu1-TJ bullets moving at a velocity of approximately 358 m/s. The results indicated that no total penetration occurred on any of the plates. The bullets were destroyed by impact, and the penetration depths of the CFRP, GFRP, and KFRP plates were 11.10, 9.95, and 22.22%, respectively. The layered structures in these plates appear to have changed the penetration behaviour compared with previous studies. In this study, delamination was the primary failure mode.
Single cocaine exposure attenuates the intrinsic excitability of CRH neurons in the ventral BNST via Sigma-1 receptors
Authors: Wu Jintao , Zhao Yue 
Published: April 2024

Abstract
The ventral bed nucleus of the stria terminalis (vBNST) plays a key role in cocaine addiction, especially relapse. However, the direct effects of cocaine on corticotropin-releasing hormone (CRH) neurons in the vBNST remain unclear. Here, we identify that cocaine exposure can remarkably attenuate the intrinsic excitability of CRH neurons in the vBNST in vitro. Accumulating studies reveal the crucial role of Sigma-1 receptors (Sig-1Rs) in modulating cocaine addiction. However, to the authors’ best knowledge no investigations have explored the role of Sig-1Rs in the vBNST, let alone CRH neurons. Given that cocaine acts as a type of Sig-1Rs agonist, and the dramatic role of Sig-1Rs played in intrinsic excitability of neurons as well as cocaine addiction, we employ BD1063 a canonical Sig-1Rs antagonist to block the effects of cocaine, and significantly recover the excitability of CRH neurons. Together, we suggest that cocaine exposure leads to the firing rate depression of CRH neurons in the vBNST via binding to Sig-1Rs.
Machine Learning for Predicting Intent of Radical Action in Text Data
Authors: Jurek-Loughrey Anna , Szabelska Anna 
Published: April 2024

Many cases of radicalism, especially violent radicalism, manifest within the context of inter-ethnic conflict and war. Research in this domain has significantly contributed to our overarching comprehension of the issue. This form of radicalism is inherently linked to the dynamics of group affiliation. However, our focus here is directed towards the individual motivation driving radical actions. While radical actions may encompass dynamics of group affiliation (e.g., the most radical pro-life activists being members of the Army of God), they also possess a substantial individual component. For instance, numerous attacks on abortion doctors or clinics are categorized as ’lone-wolf terrorism’.
In this study, we sought to examine whether state-of-the-art Machine Learning tech- nology for text analysis could effectively discern the intent behind radical actions from user-generated content. We analyzed a diverse array of radical texts published online by various activists, including anarchists, Iranian guerrilla members, Indian revolution- aries, activists from the US civil rights movement, and The Army of God. Our analysis reveals that Machine Learning models can successfully identify potential signals indica- tive of the author’s intent behind radical actions.

Published: April 2024

Purpose. Creation a computer model of electric drive of an electric vehicle with the possibility of modeling in slippage modes, as well as the subsequent determination of slippage detection method as early as possible to further reducing or preventing slippage.
Methodology. Mathematical analysis and modeling.
Findings. Mathematical models in the structural form of the control system, power converter and motor are added in a simplified way, as the blocks. For compiling a computer model, the blocks of the control system and the power converter will be assembled using models of elements of power electric circuits. The model allows the ED simulation with a huge number of parameters varying – modeling slipping processes with one or two wheels, a sharp change in engine parameters, failure of one of the components of the power circuit, etc. Using the Simulink and SimPower packages of the Matlab software package, as well as the block diagram of the electric drive, a computer model of the ED was synthesized. Computer simulation of dynamic processes in the electric drive during a collision, as well as pulling away on the road surface with a reduced coefficient of friction, was carried out. The obtained diagrams fully correspond to the real physical processes occurring in the electric vehicle and give reason to believe that the constructed mathematical and computer models are adequate. Proceeding from this, electromechanical transients in the electric drive during acceleration with slipping and one wheel runover a road surface with reduced traction were obtained and analyzed. As a result of this analysis, the most optimal and reliable way to determine the skidding mode for its further elimination was determined.
Originality. Computer model of the asynchronous electric drive of an electric vehicle with a detailed mechanical part, taking into account the mechanical differential gear, was built. The model allows the ED simulation with a huge number of parameters varying – modeling slipping processes with one or two wheels, a sharp change in engine parameters, failure of one of the components of the power circuit, etc.
Practical value. Computer simulation was carried out for two modes: start of electric vehicle movement , when one of the wheels has been of on the road surface with a reduced coefficient of adhesion (0,1) since launch and acceleration with a collision with a surface with a reduced coefficient of adhesion (0,1) with one wheel at the moment of time of 6.3 s.
50 YEARS FIELD ORIENTED CONTROL OF THREE-PHASE AC DRIVES IN THE PRACTICE - THE STATE OF THE ART
Authors: Quang Nguyen Phung 
Published: April 2024

From DC motors (DCM) we know, it is possible to independently control the two currents of the flux and torque generating. Because the two DCM circuits are completely isolated, we obtain simple adjustment algorithms that require little computing time on the microprocessor. For this reason, DCM has been at the forefront of the application of digital controls in drive control systems in the early years, especially in high-performance systems. On the contrary, the three-phase AC motor (ACM) has a complex structure due to the winding system and three-phase power supply, and has caused significant difficulties in the mathematical description of the above decoupling characteristics. The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

On the occasion of the 50th anniversary of FOC, this paper aims to provide an overview of the development status of FOC in industrial practice. The content presented deals mainly with 3-phase induction motors.

Aim. To study serum biomarker profile in patients with coronary artery disease (CAD) and psoriasis and the impact on the incidence of hospitalization for cardiovascular reasons and psoriasis.Material and methods. The study included 90 patients divided into following 3 groups: with psoriasis (n=30), coronary artery disease (CAD) (n=30) and CAD+psoriasis (n=30) in whom serum biomarkers were determined at the beginning of the study (growth stimulation expressed gene 2, N-terminal pro-brain natriuretic peptide (NT-proBNP), interleukin-17 and tumor necrosis factor alpha) and hospitalization rates were monitored over 4 years.Results. There was a significant difference in the concentrations of all biomarkers between the groups (p<0,05), with the maximum values being in the CAD+psoriasis group, except for NT-proBNP. In regression analysis, risk factors for cardiovascular hospitalizations were psoriasis (p=0,049) and increased NT-proBNP concentrations (p<0,001).Conclusion. Comorbidity leads to an increase in the serum concentration of biomarkers, while the risk factors for cardiovascular hospitalization were psoriasis and serum NT-proBNP level.

Este artigo teve como objetivo investigar a produção de sentidos e (in)tensões do Currículo da Educação Infantil, construindo um panorama histórico acerca das políticas educacionais para esta etapa de ensino no Brasil, no período da década de 1990 até os anos 2023. Adotando a abordagem qualitativa, fundamentada em Moreira (2009), que descreve que o percurso da pesquisa é flexível e se articula aos interesses e na interpretação de situações de investigação. Para a coleta de dados utilizamos a entrevista semiestruturada, realizada em agosto de 2023. O campo empírico da coleta de dados foram, três escolas municipais, sendo duas de Nazaré da Mata e uma de Carpina, ambas de Pernambuco. Para a análise dos dados utilizamos a abordagem Transversal de Escuta Sensível de René Barbie e a análise do conteúdo temático categorial de Bardin (2011). Como resultados apontamos conhecer o currículo da educação infantil é fundamental para a compreensão de educação, criança, infância, brincar e as (in)tensões que se reverberam no currículo, sobretudo porque o/a professor/a é quem está na sala de aula realizando intervenções e trabalhando diretamente com a criança dando significado as aprendizagens.
Cambios de espacios educativos: nexos o rupturas del estudiante universitario
Authors: Cadavid Marín Angela María , Calderón González Marco Felipe 
Published: April 2024

Se presentan los resultados de una investigación cualitativa, cuyo objetivo fue comprender los nexos o rupturas que experimentan algunos estudiantes universitarios en relación con los cambios de espacios educativos, a partir de su visión de realidad con el fin de visibilizar su realidad contextual. Para ello, el método elegido fue el biográfico narrativo, donde a partir de relatos de vida se pudo evidenciar que los nexos o rupturas que experimentan los estudiantes a partir de su visión de realidad, se dan en la dinámica cotidiana en relación con dichos espacios educativos, lo que lleva al rompimiento, a la acomodación y a la construcción de una nueva visión de la cotidianidad, a medida que los estudiantes hacen el cambio rural-local-urbano. De lo cual se desprende que no hay una real ruptura con lo que arraiga al estudiante, por tanto, es necesario enfocar la educación en el campo, desde los cambios de vida y no de ubicación, donde se atienda a lo específico de cada uno de ellos, lo que incluye fundamentalmente el acompañamiento y entendimiento de la vida en el hogar, el pueblo y la ciudad (y la visión de esta vida) desde el estudiante mismo.
