Authors: Ekimov E. V. , Skripkina G. I. , Garifullina A. Zh. , Chumichkin N. V.
Published: October 2023

Relevance.  To date, painless, comfortable dental treatment of adults and children remains a priority for modern dentistry. It is of note that children specifically need adequate pain relief more than others since negative emotions received in childhood can determine the relationship between the dentist and the patient for the rest of their lives. Local anaesthetics, the preferred method of anaesthesia in pediatric dentistry, come to the aid of doctors. However, the question arises about the correct selection of a local anaesthetic and its concentration. There is a lot of research on this topic; however, not all local anaesthetics used in adult patients are safe enough and justified for use in pediatric dentistry. In addition, on the market today, there are a lot of anaesthetic drugs, various forms of presentation, types, concentrations and combinations. All of the above sets high demands on the dentist.

Purpose. To analyze and systematize scientific research on local anaesthetics in pediatric dental practice.

Material and methods. The main research method was the analysis of literature on the topic. Based on established PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria, publications were searched in the Medline PubMed and E-library databases by the keywords: "pediatric dentistry", "local anaesthetics", "pain relief", and "anaesthesia".

Results. The analysis of the presented studies demonstrated a variety of used means and methods of local anaesthesia in children.

Conclusion. Pediatric dental practice dictates special rules for the treatment of patients; in each case, the doctor must take into account the data of the medical history and the level of anxiety of the child for a reasonable choice of ways and method of local anaesthesia.

Methodological problems of historical interpretation through the prism of intellectual history in the work of R. Watmore “What is Intellectual History?”
Authors:   Far Eastern Federal University, Gorbunov A. V.
Published: October 2023

This article presents some key aspects of a special humanitarian genre of intellectual history, illuminated through the prism of actual methodological problems of historical interpretation of the texts of past epochs. The subject is the original ideas of the British intellectual historian Richard Watmore, formulated in detail in his monograph «What is Intellectual History?». It is believed that the position of the author in question not only demonstrates the appearance of the most complex humanitarian field, but also gives his own unique view of current problems due to its comprehensive coverage and a single conceptual view of historical interpretation and ways of its implementation. It is made an attempt to present Watmore's approach of intellectual history systematically which is characterized by the expansion of the interdisciplinarity of contextualism, the intensification of historical analytics and cultural sensitivity.

Um aspecto característico de indivíduos autistas é o desenvolvimento de hábitos restritivos, aversivos, ritualísticos e seletivos em relação à alimentação, dificultando a ingestão de alimentos com diversidade, quantidade e qualidade, podendo desencadear o desenvolvimento de   sintomas e transtornos gastrointestinais. O objetivo desse estudo foi reunir informações disponíveis na literatura científica sobre o Transtorno do Espectro Autista (TEA) e a alimentação, destacando principalmente, as dificuldades e as alterações no hábito alimentar, as consequências geradas e as possíveis ações a serem desenvolvidas para a melhoria da segurança alimentar e nutricional dos indivíduos. Foram realizadas buscas através das bases de dados Google Acadêmico, SciELO, Periódico Capes, PubMed e Biblioteca Digital Brasileira de Teses e Dissertações (BDTD), durante o período de março a junho de 2023. Para as estratégias de buscas foram utilizados os seguintes descritores: “TEA” ou “autismo” combinados à “glúten”, “caseína”, “alimentação”, “trato gastrointestinal”, “mastigação e deglutição”, “comportamento alimentar”, “vitamina D” e “ômega-3”. Como critérios de inclusão foram utilizadas publicações entre 2013 e 2023 e nos idiomas espanhol, inglês e português. Os resultados apontaram que são muitas as dificuldades, sintomas e alterações encontradas por indivíduos com TEA em relação à alimentação, as quais limitam o consumo de alimentos de forma variada, com quantidade e qualidade e, muitas vezes, de maneira prazerosa. O estudo e a abordagem de estratégias e condutas que possam ajudar na melhoria destas condições é bastante importante dentro do espectro autista, visto a necessidade de práticas que ajudem a melhorar a qualidade de vida dos indivíduos portadores.
Trombose Mesentérica - uma revisão abrangente sobre a etiologia, fisiopatologia, epidemiologia, diagnóstico e tratamento
Authors: Guimarães Natália Silveira Franco , Amorim Bruna Mendes , Correa Fernanda Cardoso Visentin , Sousa Giovanna Vasconcelos , Zamboni Sofia Barbosa
Published: October 2023

A trombose mesentérica é uma condição clínica rara, porém grave, que envolve a obstrução das artérias ou veias que irrigam o intestino delgado e grosso. Em relação à etiologia, pode ser causada por diversos fatores, sendo a hipercoagulabilidade uma das principais. Outras causas incluem aterosclerose, cirurgia prévia, trauma abdominal, uso de contraceptivos orais e algumas condições médicas subjacentes, como doenças inflamatórias do intestino. No que se refere a fisiopatologia, a obstrução das artérias ou veias mesentéricas leva à interrupção do suprimento sanguíneo para o intestino, resultando em isquemia intestinal. Isso pode levar à necrose tecidual e, se não tratada rapidamente, à perfuração intestinal e sepse. Quanto à epidemiologia, a trombose mesentérica é uma condição relativamente rara, com uma incidência variável em diferentes populações. Ela afeta principalmente adultos, com um ligeiro predomínio em mulheres. A idade avançada e a presença de fatores de risco, como doenças cardiovasculares e trombofilias, aumentam o risco. O diagnóstico precoce é crucial para o sucesso do tratamento. Os sintomas podem variar, mas frequentemente incluem dor abdominal intensa e súbita, acompanhada de náuseas, vômitos e diarreia sanguinolenta. Exames de imagem, como a tomografia computadorizada e a angiografia, são fundamentais para confirmar o diagnóstico. Além disso, a avaliação de fatores de risco e exames laboratoriais auxiliam na identificação da causa subjacente. O tratamento da trombose mesentérica visa restaurar o fluxo sanguíneo intestinal o mais rápido possível. Isso pode ser alcançado por meio de procedimentos endovasculares, como a trombólise e a angioplastia, ou cirurgia de ressecção do tecido necrótico. A anticoagulação é frequentemente necessária para prevenir a recorrência da trombose. Além disso, a gestão dos fatores de risco subjacentes desempenha um papel importante na prevenção da trombose mesentérica.

A menopausa representa o encerramento da fase reprodutiva feminina, caracterizada pela cessação do ciclo menstrual e uma acentuada redução nos níveis de estrogênio. Nesse período, sintomas como fogachos, sudorese noturna e atrofia vaginal são comuns. Atualmente, a Terapia de Reposição Hormonal (TRH) é considerada como abordagem terapêutica de primeira escolha para o alívio dos sintomas, porém, estudos suscitaram uma possível associação da TRH com um maior risco de doenças cardíacas coronarianas e neoplasias mamárias. Contudo, análises e investigações mais recentes identificaram benefícios substanciais da terapia hormonal em mulheres que atendem a critérios específicos. Analisar e contrabalancear as vantagens e as adversidades da TRH, bem como comparar diferentes tipos e formulações, visando aprimorar sua prescrição. Revisão integrativa de literatura nas bases de dados PubMed, LILACS e SciELO, a partir do uso dos descritores: “hormone replacement therapy”, “hormone replacement therapy risks” e “hormone replacement benefits”. Foram aplicados critérios de inclusão e exclusão, resultando em 11 artigos selecionados. Os estudos apontam que a idade de início do uso de TRH influencia os benefícios e riscos, com taxas de risco mais altas em mulheres com mais de 60 anos. Além disso, aponta-se que a TRH alivia sintomas vasomotores, melhora a qualidade de sono e a saúde mental, além de ter efeitos positivos na composição corporal e na resistência à insulina, reduzindo o risco de Diabetes Mellitus. Destaca-se que o tempo de duração e o momento de início do tratamento são pontos cruciais para avaliar os possíveis riscos. A Terapia de Reposição Hormonal proporciona benefícios no alívio dos sintomas da menopausa, mas demanda uma avaliação individualizada, devido aos potenciais riscos e contra indicações. A prescrição de TRH deve ser adaptada a cada paciente e acompanhada de monitoramento médico regular.

Ein Instrument zur Bewertung der Mobilität: Der Mobilitätsindex
Authors: Rammert Alexander
Published: October 2023

Dieser Beitrag stellt ein neu entwickeltes Instrument zur Bewertung der Mobilität vor: den Mobilitätsindex. Ausgehend von der Annahme, dass Mobilität im Sinne der Bewegungsmöglichkeiten die Ursache für Verkehr ist, untersucht er, wie die tatsächlichen Möglichkeiten der Menschen – unabhängig vom entstandenen Verkehr – ausgestaltet sind. Hierfür wird zunächst ein theoretisches Modell von Mobilität entworfen, bevor im Anschluss Indikatoren aus der Wissenschaft definiert werden, welche die menschliche Mobilität messbar machen. Diese Indikatoren werden in einem Indexmodell zusammengeführt und können am Ende die Mobilität in Untersuchungsräumen anhand eines Indexwerts nachvollziehbar machen. Gezeigt wird dieses Vorgehen am Beispiel des Berliner Bezirks Pankow. Hier wird deutlich, welche neuen Perspektiven ein Mobilitätsindex für Politik und Planung bietet, indem er die Möglichkeiten der Menschen unabhängig vom Verkehr darstellen kann. Dies ist eine zentrale Voraussetzung für eine evidenzbasierte Mobilitätsplanung, deren Ziel es ist, die Ursachen für den Verkehr zielorientiert zu verändern.
Li2HfBr6 scintillator for neutron and gamma-ray dual detection
Authors: Fujiwara Chihaya , Kurosawa Shunsuke , Yamaji Akihiro , Yoshikawa Akira
Published: October 2023

Li2HfBr6 with host emission was grown as a gamma-ray- and neutron-sensitive scintillator. Decay time of Li2HfBr6 was estimated to be less than 5 μs, and single-photon counting is available to evaluate its light output. The emission wavelength under X-ray excitation was approximately 570 nm, which is a longer wavelength than that of commonly used neutron scintillators, e.g. Li-glass. The light output excited by thermal neutrons was estimated to be 52000 photons per thermal neutron, which is approximately eight to nine times higher than that of Li-glass. Additionally, neutrons and gamma rays were discriminated using the pulse-shaped discrimination technique for Li2HfBr6.
Reducing switching current with Gilbert damping constant in nanomagnets with perpendicular anisotropy under Dzyaloshinskii–Moriya interaction
Authors: Yamada Keisuke , Takamatsu Shun-ichi , Asakawa Hiroki , Nakatani Yoshinobu
Published: October 2023

We report current-induced magnetization switching (j
sw) with a nanosecond-duration pulse current (t
p) in a perpendicularly magnetized nanomagnet under the Dzyaloshinskii–Moriya interaction (DMI) and investigate the effect of the Gilbert damping constant (α), t
p, and DMI value (D) on j
sw via micromagnetic simulations. When α is sufficiently small at t
p = 1 ns, j
sw for D = 1.0 erg cm−2 decreases by 42% compared to that for D = 0 erg cm−2. Further, j
sw can be reduced under the DMI when α is small and t
p is short, which is attributed to the twisted magnetization and increased initial magnetization angle.
Observation of low-frequency Raman peak in layered WTe2
Authors: Nema Hirofumi , Fujii Yasuhiro , Oishi Eiichi , Koreeda Akitoshi
Published: October 2023

WTe2 recently attracted considerable attention as a layered material exhibiting ferroelectricity, giant magnetoresistance, and pressure-induced superconductivity. In this study, we performed Raman spectroscopy on bulk WTe2, including the low-frequency region. An unfamiliar Raman peak (P0) was found at approximately 9 cm−1 in addition to the seven already known peaks (P1–P7). Furthermore, the angular and polarization dependence of the spectra revealed the peak P0 had A
1 symmetry. The symmetry is consistent with the experimental results and first-principles calculations by other groups. Our work paves the way for studying the symmetry of the low-frequency phonons in atomic-layer ferrolectric films using Raman spectroscopy.
The formation of scientific research in the Finland gulf in the XIX–XX-th centuries and their significance for the fishery science of Russia
Authors: Lukina Yu. N. , Lukin A. A.
Published: October 2023

The results include the historical chronicle of expeditions in the eastern part of the Finland Gulf, the periodization of the formation of fisheries research with an emphasis on their role in shaping the scientific worldview in general, and the history of the creation of the scientific school, which laid the traditions of Russian fishery study. The fundamental role of science for the effective operation of the fishery industry is shown. The chronological framework of the study covers the period from 1851 to 1941, the starting point of which is the date of the officially recognized first scientific expedition on fishing issues to Lake Peipus, Pskov and the Baltic Sea. The study is aimed to a historical review of the formation of fishery research in the eastern part of the Finland Gulf and an assessment of their role for ichthyological science in general. The work is based on an analytical approach to the history of the formation of ichthyological science, including prerequisites, goals, methodology in the context of a close relationship with fisheries, and a retrospective analysis that made it possible to identify the main patterns in the development of fishery study that determined specific features in a particular historical period. The analysis of the development of Russian fishery science and its relationship with fishery in a particular region in a broad scientific, social and economic context determines the novelty of the study. The practical and theoretical significances are determined by the identification of the fundamental importance of applied research in different historical periods, which played a key role for ichthyological science in general and the economic development of the Finland Gulf in particular.
Joint Detection and Decoding over Multipath Channels
Authors: Mirbadin Anoush , Zaraki Abolfazl
Published: October 2023

We use the sum-product algorithm (SPA) on factor graphs to enable joint detection and decoding over multipath channels in single-carrier modulation formats. We simulate the multipath channels as accurately as possible at the receiver side by discretizing channel parameters, such as channel paths and attenuation coefficients, to compute means of Gaussian observations. We assign these parameters Bernoulli random variables and consider priors of 0.5 for them. We propose a novel implementation strategy to reduce the complexity of the receiver considerably.

Authors: Lu Jian-yu
Published: October 2023

A four-dimensional (4D) super-resolution imaging method (called PSF modulation method) was developed via modulation of an arbitrary point-spread-function (PSF) of an imaging system. The highest image resolution achievable will only be limited by the noises in the images. Theory, computer simulations, and experiments were presented. 

A pulse-echo image of a super-resolution (0.65 mm versus a two-way diffraction-limited resolution of 2.65 mm) and 31-dB signal-to-noise ratio (SNR) was obtained with an ultrasound experiment using a 0.5-mm diameter modulator and 1.483-mm wavelength. Another ultrasound experiment shows that a wave source was imaged at a super-resolution (0.5 mm versus a one-way diffraction limited resolution of 3.63 mm) at about 30-dB SNR, using the same modulator size and wavelength. 

In addition, a PSF-weighted super-resolution imaging method based on the PSF modulation method was developed. This method is easier to implement but may have some limitations. With a proper choice of a modulator and imaging system, nanoscale imaging is possible using the methods developed.

Emotion recognition, a process of automatic cognition of human emotions, has great potential to improve the degree of social intelligence. Among various recognition methods, Emotion recognition based on touch event's temporal and force information receives global interests. Although previous studies have shown promise in the field of keystroke-based emotion recognition, they are limited by the need for long-term text input and the lack of high-precision force sensing technology, hindering their real-time performance and wider applicability. To address this issue, in this paper, a piezoelectric-based keystroke dynamic technique is presented for quick emotion detection. The nature of piezoelectric materials enables high-resolution force detection. Meanwhile, the data collecting procedure is highly simplified because only the password entry is needed. International Affective Digitized Sounds (IADS) are applied to elicit users’ emotions, and a PAD emotion scale is used to evaluate and label the degree of emotion induction. A Random Forest (RF) based algorithm is used in order to reduce the training dataset and improve algorithm portability. Finally, an average recognition accuracy of 79.37% of 4 emotions (happiness, sadness, fear, disgust) is experimentally achieved. The proposed technique improves the reliability and practicability of emotion recognition in realistic social systems.
A method to enhance the accuracy of RF power measurements in particle accelerator high-frequency systems
Authors: Fanjian Zeng
Published: October 2023

This letter proposes a method for accurately calculating RF power at a standing wave (SW) transmission line system. It uses two directional couplers and a low-level radio frequency(LLRF) control system. The RF power is calculated from the proposed equations using amplitude and phase measurements of the coupling signals from the two directional couplers. The method is demonstrated adopting two directional couplers with directivity 26 dB and 28 dB respectively at 162.5 MHz over a whole wavelength range. The average power errors observed when using a single directional coupler are about 6.6% and 5.8% respectively, and the calculated power error can be reduced to about 1.0% through the proposed method.

Published: October 2023

Clustering plays a pivotal role in exploratory data analysis, especially in scenarios where prior knowledge about a subset of samples is available, prompting a rapid development of Semi-supervised clustering approaches. In this work, we introduce a novel method for seamlessly integrating prior knowledge into the widely recognized Normalized Cut Clustering (NCC) algorithm, thereby offering a natural extension within the realm of semi-supervised clustering. Similarly to NCC, the solution of the proposed method is spectral-based in the form of an inhomogeneous eigenvalue problem. Also, we show that the proposed method can be seen as a generalization of NCC, enhancing its applicability in scenarios where prior information is available. In addition, we design an adequate and comprehensive experimental setup. This setup not only tests the competitiveness of our approach but also showcases its superiority in terms of performance metrics.

Contribution: The study discusses the relationship between interpersonal trust and team performance in an exploratory way. The empirical data is collected from students in Electrical Engineering Practice Training Course classes to evaluate their team performance.

Background: Interpersonal trust within a team plays a critical role in solving problems and enhancing group performance effectiveness.

Research Question: Does interpersonal trust within a team have an impact on team performance? Can interpersonal trust between teammates be improved?

Design/Approach: This research presents a case study of 132 electrical engineering university students in China. The students worked in teams completing six simulation experiments in a semester.

Findings: The teams always with permanent teammates had the highest level of interpersonal trust and performed the best and the teams always with tentative teammates had the lowest level of trust interpersonal trust and performed worse and worse while the teams whose members were fixed by the instructor increased their interpersonal trust quickly and performed better and better over time.

Conclusions: The higher the interpersonal trust within a team, the better the team performance; low initial interpersonal trust within a team can be promoted through intervention.
Band structure-based simulation and analysis of 2D electrostatics in UTB DG MOSFETs from low to room temperature
Authors: Vilochan Mishra Nalin
Published: October 2023

Accurate determination of key device electrostatics parameters such as threshold voltage, Sub-Threshold Swing in Ultra-Thin Body (UTB) MOS transistors is made possible through accurate treatment of Quantum Confinement Effects (QCEs), along the channel thickness direction and Short-Channel Effects (SCEs), along the direction of the channel length. In this work, we propose a methodology to simulate the 2-D channel electrostatics of a UTB Double Gate (DG) MOS transistor structure, at room temperature, by solving the 2-D Poisson’s equation self-consistently with the 1-D band structure, thus enabling this approach to accurately take Quantum Confinement and short channel effects (SCEs) into account. By solving the 1-D band structure only once at the source-channel junction and updating the eigen energy (in the lateral direction) in the self-consistent loop, we show that this approach is able to obtain the 2-D channel electrostatics in a computationally efficient and accurate manner. By also extending this band structure-based approach to lower device temperatures, where carrier freeze-out effects manifest, we show the versatility of this approach in calculating the channel electrostatics over a wide range of device temperatures, while considering QCEs and SCEs.

 Automated vehicles use light detection and ranging (LiDAR) sensors for environmental scanning. However, the relative motion between the scanning LiDAR sensor and objects leads to a distortion of the point cloud. This phenomenon is known as the motion distortion effect, significantly degrading the sensor’s object detection capabilities and generating false negative or false positive errors. In this work, we have introduced ray tracing-based deterministic and analytical approaches to model the motion distortion effect on the scanning LiDAR sensor’s performance for simulation-based testing. In addition, we have performed dynamic test drives at a proving ground to compare real LiDAR data with the motion distortion effect simulation data. The real-world scenarios, the environmental conditions, the digital twin of the scenery, and the object of interest (OOI) are replicated in the virtual environment of commercial software to obtain the synthetic LiDAR data. The real and the virtual test drives are compared frame by frame to validate the motion distortion effect modeling. The mean absolute percentage error (MAPE), the occupied cell ratio (OCR), and the Barons cross-correlation coefficient (BCC) are used to quantify the correlation between the virtual and the real LiDAR point cloud data. The results show that the deterministic approach matches the real measurements better than the analytical approach for the scenarios in which the yaw rate of the ego vehicle changes rapidly.

Physical Layer Secret Key Generation with Kalman Filter Detrending
Authors: Mitev Miroslav , Chorti Arsenia , Fettweis Gerhard
Published: October 2023

The massive deployment of low-end wireless Internet of things (IoT) devices opens the challenge of finding de-centralized and lightweight alternatives for secret key distribution. A possible solution, coming from the physical layer, is the secret key generation (SKG) from channel state information (CSI) during the channel’s coherence time. This work acknowledges the fact that the CSI consists of  deterministic (predictable) and stochastic (unpredictable) components, loosely captured through the terms large-scale and small-scale fading, espectively. Hence, keys must be generated using only the random and unpredictable part. To detrend CSI measurements from deterministic components, a simple and lightweight approach based on Kalman filters is proposed and is evaluated using an implementation of the complete SKG protocol (including privacy amplification that is typically missing in many published works). In our study we use a massive multiple input multiple output (mMIMO) orthogonal frequency division multiplexing outdoor measured CSI dataset. The threat model assumes a passive eavesdropper in the vicinity (at 1 meter distance or less) from one of the legitimate nodes and the Kalman filter is parameterized to maximize the achievable key rate.
Machine Learning-based Robust Physical Layer Authentication Using Angle of Arrival Estimation

Published: October 2023

In this paper, we study the use of the angle of arrival (AoA) as a feature for performing robust, machine learning (ML)-based physical layer authentication (PLA). In fact, whereas most previous research on PLA relies on physical properties such as channel frequency/impulse response or received signal strength, the use of the AoA in this context has not yet been studied in depth as a means of providing resistance to impersonation (spoofing) attacks. In this study, we first prove that an effective impersonation attack on AoA-based PLA can only succeed under very stringent conditions on the attacker in terms of location and hardware capabilities, and thus, the AoA can in many scenarios be used as a robust feature for PLA. In addition, we exploit machine learning in our study to perform lightweight, model-free, intelligent PLA. We show the effectiveness of the  proposed AoA-based PLA solutions by testing them on experimental outdoor massive multiple input multiple output data.
