The Impact of Trap-Assisted Tunneling and Poole–Frenkel Emission on Synaptic Potentiation in an α-Fe2O3/p-Si Memristive Device
Authors: Mainali Punya , Wagle Phadindra , McPherson Chasen , McIlroy David. N.
Published: January 2023

A signature of synaptic potentiation conductance has been observed in an α-Fe2O3/p-Si device fabricated using spin coating. The conductance of the device in dark conditions and illumination with a white light source was characterized as a function of the application of a periodic bias (voltage) with a triangular profile. The conductance of the device increases with the number of voltage cycles applied and plateaus to its maximum value of 0.70 μS under dark conditions and 12.00 μS under illumination, and this mimics the analog synaptic weight change with the action potential of a neuron. In the range of applied voltage from 0 V to 0.7 V, the conduction mechanism corresponds to trap-assisted tunneling (TAT) and in the range of 0.7–5 V it corresponds to the Poole–Frenkel emission (PFE). The conductance as a function of electrical pulses was fitted with a Hill function, which is a measure of cooperation in biological systems. In this case, it allows one to determine the turn-on threshold (K) of the device in terms of the number of voltage pulses, which are found to be 3 and 166 under dark and illumination conditions, respectively. The gradual conductance change and activation after a certain number of pulses perfectly mimics the synaptic potentiation of neurons. In addition, the threshold parameter extracted from the Hill equation fit, acting as the number of pulses for synaptic activation, is found to have programmability with the intensity of the light illumination.

Published: January 2023

Achillea millefolium L. is the most representative plant of the genus Achillea due to its long-standing use. Previous investigations have allowed for the identification of many chemical compounds including phenols, flavonoids, monoterpenes, sesquiterpenes, and their derivatives. However, only a few reports have considered flower color in relation to A. millefolium composition. In this work, the phytochemical analysis on the volatile content of fresh samples of three morphotypes—white, pink and deep pink—collected in different points of the Italian Alpine area, was performed by the SPME-GC-MS technique. The obtained data highlighted a high content of terpenic compounds in all of the investigated morphotypes with a general predominance of monoterpenes over sesquiterpenes with the exception of the white morphotype at collection point A (Saint Marcel, Valle d’Aosta). An in-depth statistical investigation was also carried out to better interpret the distribution of the various components both in relation to the morphotype and collection point.

Published: January 2023

In this work, a simulation framework for virtual testing of autonomous driving functions under the influence of a fault occurring in a component is presented. The models consist of trajectory planning, motion control, models of actuator management, actuators and vehicle dynamics. Fault-handling tests in a right-turn maneuver are described, subject to an injected fault in the steering system. Different scenarios are discussed without and with a fault and without and with counteractions against the fault. The results of five scenarios for different criticality metrics are discussed. In the case of a fault without a counteraction, a pronounced lateral position deviation of the ego vehicle from the reference curve is observed. Furthermore, the minimal and hence most critical time-to-collision (TTC) and post-encroachment time (PET) values are calculated for each scenario together with a parameter variation of the initial position of a traffic agent. The minimum TTC values are lowest in the case of a fault without counteraction. For the lateral position deviation and the TTC, the counteractions cause reduced criticality that can become even lower than in the case without a fault, corresponding to a decrease in the dynamic behavior of the vehicle. For the PET, only in the case of a fault without counteraction, a non-zero value can be calculated. With the implemented testing toolchain, the automated vehicle and the reaction of the HAD function in non-standard conditions with reduced performance can be investigated. This can be used to test the influence of component faults on automated driving functions and help increase acceptance of implemented counteractions as part of the HAD function. The assessment of the situation using a combination of metrics is shown to be useful, as the different metrics can become critical in different situations.

Most hemoparasites hosted by wild birds appear to be harmless, but most of the blood parasite studies in avian wildlife are mainly focused on passerines or migratory species. This study aimed to assess the occurrence of blood parasites in nocturnal raptors (Strigiformes order) and their effect on hematological parameters. A total of 134 blood samples were collected during a four-year period for hematological analysis and hemoparasite detection and quantification by microscopical examination of the samples. Overall, the occurrence of hemoparasites was 35.1%, with Leucocytozoon being the most frequently detected (32.1%), followed by Haemoproteus (11.2%), Trypanosoma and Plasmodium (2.2% each). Among the different bird species, the Eurasian eagle-owl (Bubo bubo) showed the highest blood parasite positivity (94.7%). In barn owls, the positive birds displayed a lower hematocrit measurement and body condition score than the non-parasitized ones (p = 0.007 and p = 0.005, respectively), especially those parasitized by Leucocytozoon. Moreover, the analysis of the magnitude of this association revealed that the presence of hemoparasites is five times more frequent in barn owls with a 2/5 body condition score. Despite the host–parasite coevolution in Strigiformes, our results show a correlation between the presence of hemoparasites and some health parameters, including blood parameters.

Published: January 2023

The Internet is an important platform for providing sexual health information for emerging adults. However, less is known about what content is accessed, why it is accessed and what practical barriers exist. Emerging adulthood is a developmental period often associated with increased risky sexual behaviour. This study explored practical aspects of accessing online sexual health information including the type of content accessed, reasons for accessing informationand practical barriers to accessing websites. A quantitative, cross-sectional design was applied. Participants were 751 emerging adults aged 18–29 years old (M = 23.3; SD = 3.11), recruited from the Republic of Ireland. Participants completed an online survey including variables about demographics, Internet searches for sex-related information, reasons for conducting searches, important aspects and practical difficulties in accessing sexual health websites. Most participants reported using the Internet for sexual health information. Content accessed related to sexually transmitted infections, contraceptives and relationship advice. Reasons for conducting searches included curiosity, privacy and presence of infection. Important website factors were usefulness, ease of understanding and confidentiality. Practical barriers included difficulty filtering excess information, lack of relevant content and limited awareness of trusted sources. Differences were observed between genders and sexual orientations. The findings have implications for healthcare and/or public health professionals who are responsible for providing online sexual health resources for emerging adults.

Conceitos modernos para o clareamento dental: uma revisão narrativa da literatura
Authors: Paixão Alison Gustavo Pantoja , Lucas Rebeca Aguiar , Souza Gabriel Catunda de
Published: January 2023

Na sociedade atual, a aparência física e a imagem da pessoa ganharam especial importância, muitas vezes acima de outros valores mais clássicos da personalidade. Para muitas situações da vida, a boa imagem tornou-se um aspecto de enorme relevância, desde melhores expectativas na hora de conseguir um emprego até o desenvolvimento de relações interpessoais mais amplas e aceitação ou não por outras pessoas. Assim, explica-se o aumento da procura, com a Odontologia deixando de se concentrar em tratamentos mais clássicos como extrações, próteses, canais radiculares e obturações em busca de recuperar a saúde bucal do paciente para cobrar um desses tratamentos com objetivos mais estéticos como clareamento dental, que é um procedimento que se tornou uma prática comum e rotineira no consultório odontológico. A intenção deste trabalho não é fazer uma revisão narrativa da literatura das diferentes técnicas e materiais utilizados, mas mencionar os benefícios e riscos a que estão expostas as pessoas que se submetem às técnicas de clareamento. Existem diferentes técnicas para realizar o clareamento dental, todas baseadas na utilização de peróxidos de hidrogênio e carbamida em diferentes concentrações. Uma delas é a técnica ambulatorial ou domiciliar, onde os produtos são utilizados em baixas concentrações. Outra técnica é o clareamento de consultório, onde esses produtos são usados em altas concentrações. Todo procedimento deve ser sempre supervisionado pelo dentista, que deve fornecer o material e controlar sua administração, além de observar o estado dos tecidos moles do paciente e alterações de pigmentação ou deterioração de restaurações pré-existentes.
Analysis of the potential of effective microorganisms in plant production
Authors: Piotrowska Anna , Boruszko Dariusz
Published: January 2023

The natural environment is changing under the influence of human activity and the development of new technologies. One of the ways to restore the balance of the natural environment is to limit conventional agriculture in favour of organic farming based on the use of organic and natural fertilisers, excluding the use of chemical inputs. This action will go a long way in improving biodiversity and natural resource wealth. Fertilisation in modern agriculture is one of the most important agrotechnical procedures in deciding on the size and quality of the obtained crops. In organic farming, soil microorganisms play an important role because they influence the mineralisation of organic carbon and the humification of organic matter, thanks to which nutrients are more easily absorbed by plants. Organic fertilisers, which are Effective Microorganisms, are produced with the use of living microorganisms, which not only supply the soil with nutrients but also allow the inactive nutrients to be made available. Thanks to the better absorption of nutrients, plants develop and grow better, ensuring the best crops, the purchase prices of which from organic farming are very often much higher than in the case of traditional crops. The aim of this study was to present the possibility of using Effective Microorganisms as an ecological and economical alternative to conventional crop production systems using artificial fertilisers.

La presente investigación buscórevisar el ecosistemade aprendizaje para alcanzar la Educación 4.0 a través de la conectividad a internet de los 3035 alumnos de la Licenciatura en Educación Básica en la Universidad Pedagógica Veracruzana durante la pandemia, mediante una encuesta virtual realizada en el segundo semestre del ciclo escolar 2020-2021 a todos los centros regionales para identificar la disponibilidad de ese servicio por región, semestre, sexo y rango de edad. El estudio se justificó por la relevancia de las políticas públicas de la universidad para dar continuidad a las actividades académicas a distancia durante el confinamiento durante su formación inicial docente. Se empleó un enfoque cuantitativo, con un alcance descriptivo, no experimental. Los niveles de análisis de la información recabada enla encuesta a nivel estatal se delimitaron a la conexión a internet que existía en la comunidad donde se encontraban los alumnos; el servicio de internet que tenían en casa; y el equipo de cómputo con el que realizaban sus actividades escolares. Los resultados obtenidos permitieron conocer que la mayoría de los alumnos contaron con una conexión a internet en su comunidad y en su hogar para realizar sus actividades escolares durante el confinamiento enfrentando las tendencias de enseñanza; casi la mitad de todos ellos tuvieron computadora de escritorio o laptop propia, pero un porcentaje similar trabajó con su celular y el resto realizó sus tareas con un dispositivo prestado. Se concluye que, en general, el ecosistema digital de los alumnos de la LEB se caracterizó por poseer elementos básicos para su formación inicial docente a distancia durante la pandemia, aunque se señalaron oportunidades tecnológicas y de apoyo a la enseñanza que les ofrecerían mejoras en dicho entorno durante su trayectoria escolar.

HOW MACHINE LEARNING ALGORITHMS ARE USED IN METEOROLOGICAL DATA CLASSIFICATION: A COMPARATIVE APPROACH BETWEEN DT, LMT, M5-MT, GRADIENT BOOSTING AND GWLM-NARX MODELS
Authors: FAYAZ Sheikh Amir , ZAMAN Majid , BUTT Muheet Ahmed , KAUL Sameer
Published: January 2023

Rainfall prediction is one of the most challenging task faced by researchers over the years. Many machine learning and AI based algorithms have been implemented on different datasets for better prediction purposes, but there is not a single solution which perfectly predicts the rainfall. Accurate prediction still remains a question to researchers. We offer a machine learning-based comparison evaluation of rainfall models for Kashmir province. Both local geographic features and the time horizon has influence on weather forecasting. Decision trees, Logistic Model Trees (LMT), and M5 model trees are examples of predictive models based on algorithms. GWLM-NARX, Gradient Boosting, and other techniques were investigated. Weather predictors measured from three major meteorological stations in the Kashmir area of the UT of J&K, India, were utilized in the models. We compared the proposed models based on their accuracy, kappa, interpretability, and other statistics, as well as the significance of the predictors utilized. On the original dataset, the DT model delivers an accuracy of 80.12 percent, followed by the LMT and Gradient boosting models, which produce accuracy of 87.23 percent and 87.51 percent, respectively. Furthermore, when continuous data was used in the M5-MT and GWLM-NARX models, the NARX model performed better, with mean squared error (MSE) and regression value (R) predictions of 3.12 percent and 0.9899 percent in training, 0.144 percent and 0.9936 percent in validation, and 0.311 percent and 0.9988 percent in testing.

Building Materials and Architectural Details of Natural Stone used in the 13th Century Castle Buildings of King Daniel in the City of Chełm
Authors: Bevz Mykola , Gazda Lucjan , Gołub Stanisław
Published: January 2023

The city of Chełm (Kholm in the past; today located on the territory of Poland) was founded by King of Rus` (Ruthenia) Danylo (Daniel) Romanovych in the middle of the 13th century. Initially, it was a small town with a small castle, but later Daniel rebuilt it and turned it into his capital. Unfortunately, buildings from the 13th century are preserved here only in the form of archaeological remains of the foundations and lower parts of the walls. The great historical significance of this city prompted us to study its building structure. It is important to know from which materials and in which technological solutions a large metropolitan city could have emerged in such a short time in the 13th century. The archaeological reports were the main source base for the study. Reports reflect all results of in-situ fixations of the walls and foundations remains of the castle. These fixations were carried out directly during archaeological research. The analysis shows that Chełm was built using materials from both local deposits and imported ones. Various stone raw materials and bricks were used for construction. It turned out that the main rock for the construction of walls and the manufacture of decorative architectural details was glauconite. The largest quantities of this raw material were used for the castle. Limestone, sandstone, opoka, and fossilized chalk were also used. The nature of the processing of stone materials shows that the builders of the castle had extensive technological knowledge and conducted numerous experiments with materials. The results of the study give an understanding of how castle buildings were erected in the 13th century both in technological and artistic aspects.
Aging-robust amplifier composed of p-type low voltage OTFT and organic semiconductor load
Authors: Kaneiwa Yuto , Kuribara Kazunori , Sato Takashi
Published: January 2023

This paper proposes an amplifier circuit design suitable for low-voltage organic thin-film transistors (OTFTs). To overcome the issues common to low-voltage OTFTs, such as the yield, degradation, and performance differences between p-type and n-type TFTs, we design the circuit based on an inverter comprising only p-type transistors. The optimal bias voltage for the amplifier stage is provided through a bias circuit. The transistor performance degradation is compensated for by sharing the gate bias voltage (i.e. the main cause of degradation) between the bias and amplifier stages. In addition, an organic semiconductor is used as a passive load of the amplifier to reduce the area and failure probability. Test chip measurements demonstrate that the organic material operates as a resistor. The gain and cut-off frequencies of the proposed amplifier circuit can be adjusted by changing the size of the dinaphtho[2,3-b:2’,3’-f]thieno[3,2-b]-thiophene resistor, providing a maximum gain of 27 dB. The proposed circuit can operate continuously for over 100 min without significant characteristic changes. The operation of the bias circuit, when applied to a differential amplifier design, is also verified. The differential amplifier achieves a maximum common-mode rejection ratio of 25 dB.
Aerial intense ultrasonic source integrating the horn and vibrating plate
Authors: Miura Hikaru
Published: January 2023

The components of conventional high-intensity aerial ultrasonic sources, including the horn, longitudinal vibrating resonance bar, and transverse vibrating plates, are usually constructed separately. In this paper, a compact ultrasonic source that integrates all component parts was developed. First, the structure of the ultrasonic source was designed by simulation analysis with the finite element method. Next, an actual ultrasonic wave source was manufactured, and its electrical characteristics, vibration characteristics, and sound pressure distribution characteristics were measured. The ultrasonic source formed a strong standing wave sound field in the air, even though the total length was one wavelength of the longitudinal vibration. For an input electric power of 10 W, a high sound pressure in the standing wave sound field of 3.44 kPa was obtained (sound pressure level of about 165 dB).

Hybrid IRS-Assisted Secure Satellite Downlink Communications: A Fast Deep Reinforcement Learning Approach
Authors: Ngo Quynh , Phan Tran Khoa , Mahmood Abdun , Xiang Wei
Published: January 2023

This paper studies a secure satellite-terrestrial communication system assisted by a hybrid intelligent reflecting surface (IRS). The hybrid IRS, which composes of active and passive reflecting elements, is deployed to enhance the secure communication from the satellite to multiple users against multiple eavesdroppers. A joint design optimization problem for the satellite beamforming and the hybrid IRS interaction is formulated to maximize the system worst-case secrecy rate under time-varying channel conditions. With high system dynamic and complexity, deep reinforcement learning (DRL) is employed to solve the non-convex optimization problem. We propose a fast DRL algorithm, namely deep PDS-DPG, to obtain the robust secure beamforming design for satellite and hybrid IRS. Numerical results show a better learning efficiency of the proposed algorithm as to the state-of-the-art deep deterministic policy gradient (DDPG) algorithm with comparable system secrecy performance. 
MapReduce for Graphs Processing: New Big Data Algorithm for 2-Edge Connected Components and Future Ideas
Authors: Dahiphale Devendra
Published: January 2023

Finding connectivity in graphs has numerous applications, such as social network analysis, data mining, intra-city or inter-cities connectivity, neural network, and many more. The deluge of graph applications makes graph connectivity problems extremely important and worthwhile to explore. Currently, there are many single-node algorithms for graph mining and analysis; however, those algorithms primarily apply to small graphs and are implemented on a single machine node. Finding 2-edge connected components (2-ECCs) in massive graphs (billions of edges and vertices) is impractical and time-consuming, even with the best-known single-node algorithms. Processing a big graph in a parallel and distributed fashion saves considerable time to finish processing. Moreover, it enables stream data processing by allowing quick results for vast and continuous nature data sets. This research proposes a distributed and parallel algorithm for finding 2-ECCs in big undirected graphs (subsequently called ”BiECCA”) and presents its time complexity analysis. The proposed algorithm is implemented on a MapReduce framework and uses an existing algorithm to find connected components (CCs) in a graph as a sub-step. Finally, we suggest a few novel ideas and approaches as extensions to our work.

Published: January 2023

Hereby, we present a new design for an integrated wavelength meter. The device works by coupling an unknown monochromatic light source to four microring resonators of different free spectral range containing a phase modulator. The output of each ring is coupled to a separate photodiode (PD). The setup relies on modulating the spectral position of ring resonances while monitoring transmitted power with PDs. Thanks to data acquired during calibration, is possible to relate such output powers to a unique wavelength. While state-of the art designs allow for either high precision or broad range, our system does not require any tradeoff between those two characteristic, achieving up to 8 pm precision (for a ring Q factor equal to 2*10^5) and 100 nm of wavelength range. We will discuss how losses influence the measurement speed and the resolution of the device. The structure, although platform independent, will be realized in InP.
Effects of Soil Amendments on Arsenic Uptake by Earthworms(Eisenia fetida) in Arsenic-Polluted Soil

Published: January 2023

This study was conducted to evaluate the effects of soil amendments on arsenic (As) bioavailability in As-polluted soils. We determined the subsequent changes in As toxicity toward earthworms (Eisenia fetida) and As uptake by earthworms. We also investigated whether As bioaccumulation could be used as an index to evaluate changes in quality of As-polluted soils. No significant changes in acute toxicity to earthworms were observed, and the observed increases (70-93 mg kg-1) or decreases (27-38 mg kg-1) in bioavailable As in soils at the end of test were not related to the As concentrations in earthworms. The As concentration in earthworms 14 days after exposure was significantly lower in calcium superphosphate (CSP)- and S-treated soils (101.4-112.8 mg kg-1) than in control soil (138.9 mg kg-1), probably owing to reduced earthworm growth due to lower pH in CSP- and S-treated soils (6.3-7.3) relative to control and steel slag-treated soils (7.5-8.4). Comparisons of As toxicity and the effects of soil properties on this toxicity toward various species of earthworms could facilitate the use of earthworms to produce biological indices for evaluating changes in quality of As-polluted soils following amendment treatments.

Published: January 2023

Objective: This study aimed to assess the performance of the CURB-65, the quick COVID-19 severity index (qCSI), and the Brescia-COVID respiratory severity scale (BCRSS) scores in predicting ICU (intensive care unit) hospitalization and in-hospital mortality in emergently hospitalized patients with COVID-19 pneumonia.

Materials and Methods: We retrospectively reviewed the emergently hospitalized 258 patients with COVID-19 pneumonia consecutively. The required sample size was calculated to compare the areas under the two ROC (receiver operating characteristic) curves (AUC) using the MedCalc 20.0 program (MedCalc Software Ltd., Ostend, Belgium). In addition, we actualized ROC analyses of the CURB-65, the qCSI, and the BCRSS scores and compared the ROC curves of these three scores.

Results: The median age of the patients was 73, and 63.6% (n=164) were male. Of 258 patients, 29.5% (n=76) were hospitalized in the intensive care unit (ICU), and 15.9% (n=41) died. The CURB-65 and the qCSI scores predicted ICU admission at a moderate level (p≤0.001; AUC values were 0.743 and 0.723, respectively). However, the predictive effect of the BCRSS score for ICU admission was lower (p≤0.001; AUC value was 0.667). The CURB-65 predicted in-hospital mortality at a moderate level (p≤0.001; AUC value was 0.762). However, the predictive effect of the qCSI and the BCRSS scores for in-hospital mortality were lower (p≤0.001 and p=0.012, respectively; AUC values were 0.655 and 0.612, respectively).

Conclusion: The CURB-65 score predicted ICU hospitalization and in-hospital mortality better than the qCSI and the BCRSS scores. Also, the qCSI score predicted ICU admission better than the BCRSS score.The predictive effect of the BCRSS score was the lowest. We recommend future studies to evaluate the value and utility of COVID-19 risk classification models.

Using a neural network for predicting of wear resistance of the cutting tool
Authors:   Dyakov I.F. Moiseev YU.V.
Published: January 2023

The possibilities of using a neural network to predict the wear resistance of a cutting tool in the processing of parts with typical elements are outlined. The types of neural networks used in mechanical engineering are shown. The work of the neural network is to transform input vectors into output vectors, taking into account the weight coefficients of their relationships. The measure of the consistency of the weight values was checked by determining the correlation coefficient of each parameter affecting the wear of the tool separately, and then they were summed up. The results of using a neural network are given.
