Ultrasound Ultrafast Power Doppler Imaging with High Signal-to-Noise Ratio by Temporal Multiply-and-Sum (TMAS) Autocorrelation
Authors: Shen Che-Chou , Guo Feng-Ting
Published: November 2022

Coherent plane wave compounding (CPWC) reconstructs transmit focusing by coherently summing several low-resolution plane-wave (PW) images from different transmit angles to improve its image resolution and quality. The high frame rate of CPWC imaging enables a much larger number of Doppler ensembles such that the Doppler estimation of blood flow becomes more reliable. Due to the unfocused PW transmission, however, one major limitation of the Doppler estimation in CPWC imaging is the relatively low signal-to-noise ratio (SNR). Conventionally, the Doppler power is estimated by a zero-lag autocorrelation which reduces the noise variance, but not the noise level. A higher-lag autocorrelation method such as the first-lag (R(1)) power Doppler image has been developed to take advantage of the signal coherence in the temporal direction for suppressing uncorrelated random noises. In this paper, we propose a novel Temporal Multiply-and-Sum (TMAS) power Doppler detection method to further improve the noise suppression of the higher-lag method by modulating the signal coherence among the temporal correlation pairs in the higher-lag autocorrelation with a tunable pt value. Unlike the adaptive beamforming methods which demand for either receive–channel–domain or transmit–domain processing to exploit the spatial coherence of the blood flow signal, the proposed TMAS power Doppler can share the routine beamforming architecture with CPWC imaging. The simulated results show that when it is compared to the original R(1) counterpart, the TMAS power Doppler image with the pt value of 2.5 significantly improves the SNR by 8 dB for the cross-view flow velocity within the Nyquist rate. The TMAS power Doppler, however, suffers from the signal decorrelation of the blood flow, and thus, it relies on not only the pt value and the flow velocity, but also the flow direction relative to the geometry of acoustic beam. The experimental results in the flow phantom and in vivo dataset also agree with the simulations.

Rotating-coil measurement systems are widely used to measure the multipolar fields of particle accelerator magnets. This paper presents a rotating-coil measurement system that aims at providing a complete data set for the characterization of quadrupole magnets with small bore diameters (26 mm). The PCB magnetometer design represents a challenging goal for this type of transducer. It is characterized by an aspect ratio 30% higher than the state of the art, imposed by the reduced dimension of the external radius of the rotating shaft and the necessity of covering the entire magnet effective length (500 mm or higher). The system design required a novel design for the mechanical asset, also considering the innovation represented by the commercial carbon fiber tube, housing the PCB magnetometer. Moreover, the measurement system is based primarily on standard and commercially available components, with simplified control and post-processing software applications. The system and its components are cross-calibrated using a stretched-wire system and another rotating-coil system. The measurement precision is established in a measurement campaign performed on a quadrupole magnet characterized by an inner bore diameter of 45 mm.

The rapid growth of the world population has increased the food demand as well as the need for assurance of food quality, safety, and sustainability. However, food security can easily be compromised by not only natural hazards but also changes in food preferences, political conflicts, and food frauds. In order to contribute to building a more sustainable food system—digitally visible and processes measurable—within this review, we summarized currently available evidence for various information and communication technologies (ICTs) that can be utilized to support collaborative actions, prevent fraudulent activities, and remotely perform real-time monitoring, which has become essential, especially during the COVID-19 pandemic. The Internet of Everything, 6G, blockchain, artificial intelligence, and digital twin are gaining significant attention in recent years in anticipation of leveraging the creativity of human experts in collaboration with efficient, intelligent, and accurate machines, but with limited consideration in the food supply chain. Therefore, this paper provided a thorough review of the food system by showing how various ICT tools can help sense and quantify the food system and highlighting the key enhancements that Industry 5.0 technologies can bring. The vulnerability of the food system can be effectively mitigated with the utilization of various ICTs depending on not only the nature and severity of crisis but also the specificity of the food supply chain. There are numerous ways of implementing these technologies, and they are continuously evolving.
Energy Internet Opportunities in Distributed Peer-to-Peer Energy Trading Reveal by Blockchain for Future Smart Grid 2.0
Authors: Zafar Bassam , Ben Slama Sami
Published: November 2022

The Energy Internet (EI) and Smart Grid 2.0 (SG 2.0) concepts are potential challenges in industry and research. The purpose of SG 2.0 and EI is to automate innovative power grid operations. To move from Distribution Network Operators (DSO) to consumer-centric distributed power grid management, the blockchain and smart contracts are applicable. Blockchain technology and integrated SGs will present challenges, limiting the deployment of Distributed Energy Resources (DERs). This review looks at the decentralization of the Smart Grid 2.0 using blockchain technology. Energy trading has increased due to access to distributed energy sources and electricity producers who can financially export surplus fuels. The energy trading system successfully combines energy from multiple sources to ensure consistent and optimal use of available resources and better facilities for energy users. Peer-to-peer (P2P) energy trading is a common field of study that presents some administrative and technical difficulties. This article provides a general overview of P2P energy exchange. It discusses how blockchain can improve transparency and overall performance, including the degree of decentralization, scalability, and device reliability. The research is extended to examine unresolved issues and potential directions for P2P blockchain-based energy sharing in the future. In fact, this paper also demonstrates the importance of blockchain in future smart grid activities and its blockchain-based applications. The study also briefly examines the issues associated with blockchain integration, ensuring the decentralized, secure and scalable operation of autonomous electric grids in the future.
A Diagnostic Method Based on Active Thermography for the Degradation Assessment of Power Plant Boiler Tubes
Authors: Zator Sławomir , Tomaszewski Michał , Lasar Mirosław
Published: November 2022

Proper maintenance management of power infrastructure requires inspections, in order to gather knowledge about the facility’s current condition. For this purpose, periodic diagnostic tests are carried out, not only to determine the current state, but to also predict future conditions, and subsequently plan for the scope of necessary repair work. Currently, in the case of heat screens of power boilers, the diagnostic process takes many days, is very expensive, and usually does not cover the entire screen area. Therefore, it is necessary to develop new, noninvasive diagnostic methods. This study presents the concept and research for an alternative method of locating places with excessive energy boiler screen degradation that require replacement. It was assumed that the new method should be fast, require no scaffolding assembly, and permit checking of the entire screen surface; this is unlike the methods used currently, which require manual checking of selected screen tubes. The proposed method is based on active thermography, in which heat flux is forced by the liquid flowing inside the screen. Tests were carried out based on a model of an axial-symmetric system in the form of a tube, with controlled reductions in the wall thickness. An experiment was carried out many times by recording the pipe surface temperature in many characteristic places (different thicknesses of the tube walls) with a thermal imaging camera. A temperature change was forced by a controlled flow of hot or cold water. The methods of analysis were proposed and verified, allowing firstly, detection of places with a reduced wall thickness, and secondly, estimations of the wall thickness (i.e., excessive degradation). For the best-proposed model (one of the four analyzed), all of the thickness changes were detected, and the limit error of thickness obtained was 0.3 mm.

Authors: Zhang Kai , Li Shengqing , Su Yuanda , Tan Baohai , Zhang Bo
Published: November 2022

Well logging is performed in oil and gas exploration wells to obtain the physical characteristics of underground formations. Thereafter, these wells are cased. Through-casing logging is important in mature fields and for wells that are cased without logging due to borehole stability issues. Acoustic through-casing logging is a challenging issue due to the strong interference of casing waves in formation waves, especially when the casing and formation are poorly bonded. An acoustic tool with dual-source transmitters is developed, in which an additional transducer is added to suppress casing waves. First, the operation principle and the overall design of the tool are carried out, including the span distance between the two transmitting transducers and the spacing distance between the transmitting transducer and the receiving transducers. Thereafter, a dual-source transmitting circuit is designed to send out two excitation signals of opposite polarities. These signals possess good consistency, high emission power, and precise signal adjustment. Lastly, the tool is tested in cased exploration wells in China. The experiment endings show that about 90% of the casing waves are canceled. By suppressing the casing wave amplitude, the cased-hole acoustic logging can be used commercially to obtain trustworthy formation information.
An Improved RAPID Imaging Method of Defects in Composite Plate Based on Feature Identification by Machine Learning
Authors: Deng Fei , Zhang Xiran , Yu Ning , Zhao Lin
Published: November 2022

The RAPID (reconstruction algorithm for probabilistic inspection of defect) method based on Lamb wave detection is an effective method to give the position information of a defect in composite plate. In this paper, an improved RAPID imaging method based on machine learning (ML) is proposed to precisely visualize the location and features of defects in composite plate. First, the specific feature information of the defect, such as type, size and direction, can be identified by analyzing the detection signals through multiple machine learning models. Then, according to the obtained defect features, the scaling parameter β of the RAPID method which controls the size of the elliptical area is revised, and weights are set to the important detection paths which are related to defect features to realize precise defect imaging. The simulation results show that the proposed method can intuitively characterize the location and related feature information of the defect, and effectively improve the accuracy of defect imaging.

Authors: Kuchmenko Tatiana , Menzhulina Daria , Shuba Anastasiia
Published: November 2022

Currently, antibiotics are often prescribed to children without reason due to the inability to quickly establish the presence of a bacterial etiology of the disease. One way to obtain additional diagnostic information quickly is to study the volatile metabolome of biosamples using arrays of sensors. The goal of this work was to assess the possibility of using an array of chemical sensors with various sensitive coatings to determine the presence of a bacterial infection in children by analyzing the equilibrium gas phase (EGP) of urine samples. The EGP of 90 urine samples from children with and without a bacterial infection (urinary tract infection, soft tissue infection) was studied on the “MAG-8” device with seven piezoelectric sensors in a hospital. General urine analysis with sediment microscopy was performed using a Uriscan Pro analyzer and using an Olympus CX31 microscope. After surgical removal of the source of inflammation, the microbiological studies of the biomaterial were performed to determine the presence and type of the pathogen. The most informative output data of an array of sensors have been established for diagnosing bacterial pathology. Regression models were built to predict the presence of a bacterial infection in children with an error of no more than 15%. An indicator of infection is proposed to predict the presence of a bacterial infection in children with a high sensitivity of 96%.

Published: November 2022

Clitoria ternatea is a native plant with medicinal and nutritive significance in Asia. The goal of this work was to examine the antiproliferative role of Clitoria ternatea against colorectal (HCT116), breast (MCF-7), and thyroid (TT) cancer cell lines at cellular and molecular levels. A phytochemical analysis, the cytotoxic effect, an apoptotic induction cell cycle analysis, and the expression level of GAX, DIABLO, and NAIP1 genes were assessed. The plant extract exhibited a clear cytotoxic action against the utilized cancer cell lines via a low IC50, foremost by means of cell cycle arrest at the pre-G0, G1, and S phases associated with an apoptotic induction. An apparent raise in the mRNA levels of GAX and DIABLO and a concomitant decrease in the NAIP1 mRNA level were observed in the used cancer cells treated with the IC50 of the plant extract. This study concluded that an ethanolic extract of Clitoria ternatea induced apoptotic cell death, suggesting that it could possibly be utilized as a new source of an apoptosis-inducing anticancer agent for colon, breast, and medullary thyroid cancer cell line treatments with further detailed studies.

Published: November 2022

Protective coatings can prolong the lifespan of engineering components. Electroless Ni-P coating is a very hard coating with high corrosion resistance, but low toughness. The addition of NiTi nanoparticles into the coating has shown the potential to increase the toughness of electroless Ni-P and could expand its usability as a protective coating for more applications. However, the study of the tribological behaviour and wear mechanisms of Ni-P-NiTi composite coating has been minimal. Furthermore, there is no studies on the effect of coating thickness on monolithic and composite electroless Ni-P coating wear behaviour. The wear rates of each coating were found by measuring the volume loss form multi-pass wear tests. The wear tracks were examine using a confocal microscope to observe the wear mechanisms. Each sample was tested using a spherical indenter and sharp indenter. It was found that the NiTi nanoparticle addition displayed toughening mechanisms and did improve the coating’s wear resistance. The 9 μm thick Ni-P-NiTi coating had less cracking and more uniform wear than the 9 μm thick Ni-P coating. For both the monolithic and composite coatings, their thicker version had higher wear resistance than their thinner counterpart. This was explained by the often observed trend in coatings where it has higher tensile stress near the substrate interface, which decreases and becomes compressive as thickness increases. Overall, the 9 μm thick Ni-P-NiTi coating had the highest wear resistance out of all the coatings tested.

Published: November 2022

This paper presents a spatial analysis of the incidence rate of COVID-19 cases in the state of Paraná, Brazil, from June to December 2020, and a study of the incidence rate of COVID-19 cases associated with socioeconomic variables, such as the Gini index, Theil-L index, and municipal human development index (MHDI). The data were provided from the Paraná State Health Department and Paraná Institute for Economic and Social Development. For the study of spatial autocorrelation, the univariate global Moran index (I), local univariate Moran (LISA), global Geary (c), and univariate local Geary (ci) were calculated. For the analysis of the spatial correlation, the global bivariate Moran index (Ixy), the local multivariate Geary indices (CiM), and the bivariate Lee index (Lxy) were calculated. There is significant positive spatial autocorrelation between the incidence rate of COVID-19 cases and correlations between the incidence rate of COVID-19 cases and the Gini index, Theil-L index, and MHDI in the regions under study. The highest risk areas were concentrated in the macro-regions: east and west. Understanding the spatial distribution of COVID-19, combined with economic and social factors, can contribute to greater efficiency in preventive actions and the control of new viral epidemics.
Ritual and Necessity. Practices of Diary Writing in Occupation Diaries from Brussels
Authors: Aerts Janna
Published: November 2022

En tant que genre, le journal intime est souvent associé à la crise : les individus y recourent pour consigner les souffrances et épreuves qu’ils endurent. Cet aspect prend d’autant plus d’importance en temps de guerre et d’occupation. Tenir un journal devient alors un indispensable rituel de réflexion, permettant à l’auteur de donner un sens à la réalité qui l’entoure. Cet article étudie le rôle joué par l’écriture intime dans la vie quotidienne des diaristes durant la crise de la Seconde Guerre mondiale. Les journaux tenus sous l’Occupation par Ernest Claes, August Vermeylen et Jan Walravens, trois écrivains néerlandophones qui résidaient à Bruxelles pendant le conflit mondial, feront l’objet d’un éclairage particulier. En analysant les métaréférences de ces auteurs à leur propre pratique diariste, on voit dans quelle mesure ce rituel d’écriture intime fut marqué par la vie quotidienne sous l’Occupation.
Prédestiné à l’état religieux ? Le lépreux dans la pastorale de l’Église au XIIIe siècle
Authors: Tabuteau Bruno
Published: November 2022

Au siècle de saint François et de saint Louis, la vigoureuse pastorale de l’Église rend pleinement compte, au sujet des lépreux, d’une réalité bien plus complexe et dynamique que le cliché historiographique des parias, victimes de la ségrégation sanitaire d’un Moyen Âge monolithique. Latran iii, en 1179, avait validé l’identité et l’autonomie ecclésiastiques des léproseries. Le concile provincial de Paris, en 1213, a prescrit l’adoption d’une règle, la profession religieuse et le port de l’habit. Les lépreux menant la vie commune sont alors assimilés ou comparés par certains auteurs à des religieux, dans un même idéal de perfection. Mais au fil du siècle, s’opère un «basculement du regard » . On insiste davantage sur leur grande vulnérabilité morale et spirituelle. Leurs liens matrimoniaux, par exemple, et l’impatience ou l’intempérance de leur comportement, contrarient l’idée de leur «prédestination à l’état religieux » . À l’heure, qui plus est, d’une altération de l’esprit communautaire dans les léproseries, au préjudice de la fraternité des malades.

Published: November 2022

Background: The increase in demand for emergency services causes overcrowding in emergency departments. Length of stay in emergency departments also influences overcrowding in emergency departments and is a key factor for monitoring the performance in emergency departments. This study investigated the factors affecting length of stay in patients referred to emergency department in Bandar Abbas, Iran. Methods: This retrospective cross-sectional study was conducted from December 2018 and February 2019 by investigating 234 eligible patients referred to Emergency Department of Shahid Mohammadi. Demographic characteristics were also recorded, which included gender, age, type of disease, triage level, the time for entry to emergency specialist visit, specialist visit to order time, entry to imaging/lab assay, entry to other specialist consultants, and time for entry to final decision. Results: The results did not indicate any significant difference in both genders and all age groups (P>0.05), but entry time to lab/imaging assays was significantly lower in patients under 40 years old (P=0.001). Moreover, specialist visit to order time (P=0.001), entry to lab/imaging assays (P=0.003), and entry to final decision time (P=0.013) were significantly shorter in the patients with cardiac diseases. Furthermore, entry to specialist visit time (P=0.001), entry to lab/imaging assays time (P=0.0212), and entry to final decision time (P=0.004) were significantly lower in the patients with lower levels of triage. Conclusions: Triage levels are contributing factors for lengths of stay in emergency department, and these factors can be used for decreasing emergency department lengths of stay.

Published: November 2022

Introduction: Regarding the crucial role of geographic factors in different mechanisms underlying bacterial antibiotic resistance worldwide, it is necessary to design and conduct studies to determine the prevalence and specific underlying mechanisms of this phenomenon. Objectives: This study was performed to assess the prevalence of carbapenem-resistant gram-negative bacilli which produce carbapenemase, in Loghman Hakim hospital, Tehran. Patients and Methods: In this cross-sectional study, antibiotic resistance of 300 samples of gram-negative bacilli from different patients was evaluated; 145 of which were identified as carbapenem-resistant. Carbapenemase enzyme production in these samples was assessed by the modified carbapenem inactivation method (mCIM). Results: About 81% of the samples were collected from the intensive care unit. In terms of sample type, most samples were obtained from trachea and urine culture. Acinetobacter baumannii (43%) was the most common carbapenem-resistant strain. Klebsiella pneumoniae (38%) and Pseudomonas aeruginosa (11%) ranked as the second and third most common strains, respectively. Based on mCIM evaluation, 82% of carbapenem resistance was due to the presence of carbapenemase enzyme which showed no significant difference neither between the both genders nor in various sample types. However, among carbapenemase-resistant bacilli, the presence of carbapenemase enzyme was significantly higher in A. baumannii (92%) and Escherichia coli (80%) and also in patients older than 50 years old. Conclusion: The findings of the present study showed that half of the collected gram-negative bacilli were resistant to carbapenem, of which 82% was due to the carbapenemase enzyme. The presence of the carbapenemase enzyme was higher in older patients as well as in Acinetobacter baumannii and Escherichia coli strains.

Authors: Roshan Bijan , Sadighpour Tella
Published: November 2022

The renin–angiotensin–aldosterone system (RAAS) cascade has a significant effect on several systems. Angiotensin II (AngII) has appeared as not only a vasoactive peptide but also as a multifunctional cytokine that displays several non-hemodynamic properties beyond renal hemodynamic properties. The kidney includes total components of the RAAS such as aldosterone and AngII not only adjust renal hemodynamics and reabsorption of sodium but also activating various inflammatory and fibrotic responses. Inhibition of the RAAS is one of the most potent methods to impede the development of renal diseases such as chronic kidney disease (CKD) and its related problems such as high blood pressure and heart disorders. Aliskiren, an octanamide, nonpeptide piperidine, orally, active, first commercially available, and direct renin inhibitor (DRI), impedes RAAS and operates by attaching to the active sites of renin and may be effective for the management of renal disease because of blocking the RAAS at its point of start and most sensitive step. Based on numerous studies, aliskiren is the greatest powerful inhibitor of AngII extents among RAAS inhibitors, even though it is unable to prevent the (pro) renin receptor-mediated extracellular signal-regulated kinase 1 and 2 (ERK1/2) activations. In this review, it is described renoprotective effects of aliskiren against different types of nephropathy such as acute kidney injury, diabetic nephropathy, and hypertensive nephropathy.

Recently, a few different vaccines have been developed to help end the COVID-19 pandemic. These vaccines have made significant progress toward controlling the disease. Multiple factors contribute to the immunity level that these vaccines can stimulate, including sex. The effect of gender on other vaccines’ efficacy has been studied before. The results of these studies are mentioned below. Genetic and hormonal differences between men and women are among the mechanisms suggested for the difference in vaccine efficacy in men and women. Sex hormones play various roles in stimulating or suppressing the immune system. As a result, they are responsible for the intensity and speed at which the vaccine establishes the immune response. In this narrative review study, we discuss the differences in COVID-19 vaccine efficacy and safety between the two genders and the reasons for these differences.

Published: November 2022

Background and aims: Cervical cancer is one of the most common cancers of the female reproductive system. Despite the importance of cervical cancer screening in early detection, the uptake of screening is poor. The present study aimed to predict the factors that influence the cervical cancer screening behavior of Iranian women visiting health centers. Methods: This cross-sectional study was performed on 661 women of reproductive age referred to health centers in Karaj, Iran, in 2021, who were selected by convenience sampling. Data collection was performed with a multi-sectional questionnaire designed to collect information about demographic characteristics and constructs of Protection Motivation Theory (PMT) and emotional support. Data analysis was performed using SPSS version 24.0, and AMOS version 24. Results: The mean age of the participants was 38.2±13.77. Most of the participants had a high school diploma and a moderate socioeconomic status. The results showed the direct effect of intention on behavior (β=0.54) and the direct effect of fear on intention (β=-0.66). Perceived self-efficacy had the greatest indirect effect on behavior through intention (β=0.34). All protection motivation constructs except response cost (β=0.06) showed a significant effect on cervical cancer screening behavior. Model fit indices showed the good capability of the extended protection motivation model to predict cervical cancer screening behavior. Conclusion: Perceived self-efficacy is the strongest predictor of cervical cancer screening behavior, and emotional support affects this behavior through self-efficacy and intention. Therefore, it is recommended to pay attention to these factors when designing and planning educational interventions for improving cervical cancer screening behavior.

Published: November 2022

La última novela de Valeria Luiselli, Desierto sonoro (2019), se centra en el conflicto migratorio que tuvo lugar en EE.UU. en 2014 y se construye sobre una paradoja: dar testimonio sobre aquello que ya no está y que resulta irrecuperable. Con este objetivo, Luiselli lleva a cabo una indagación del campo operacional del archivo para encontrar una estructura formal que le permita hacer hablar al documento a partir de aquellos espacios que expresan silencios dentro del mismo. En esta dirección, los hijos de la narradora y sus juegos ocupan un lugar central en la novela, ya que estos generan una zona de procesamiento de la imposibilidad de capturar aquello que ya no está. La novela encuentra en dicha situación una forma de resolver la tensión planteada alrededor del archivo, sus ausencias y los niños migrantes desaparecidos en tránsito.

Su origen se vincula a la extensión de un ramal ferroviario de la compañía The Forestal Land, Timber and Railways, a mediados de la década de 1920, cuyo propósito era la explotación de los bosques de quebracho colorado ubicados al norte de la localidad de Olmos y al oeste de la red pública del Ferrocarril Santa Fe. El objetivo de este artículo es establecer la fecha fundacional de la localidad, como así también, reflexionar sobre la participación de la comunidad en la gestión de su patrimonio memorial. El estudio incluye el análisis de documentos históricos primarios relacionados a las compañías forestales que operaron en la región y a la construcción y prolongación de sus ramales particulares vinculados a la red pública. Se incluyen además testimonios de vecinos y una primera aproximación a la disposición espacial del lugar junto con la identificación de inmuebles vinculados a ese pasado. Finalmente, se mencionan las diferentes acciones establecidas por la comunidad de Pozo de los Indios a partir de la investigación.

El casco histórico del pueblo de Payogasta (Cachi, provincia de Salta), ubicado en las proximidades de la margen derecha del río Calchaquí, fue el centro de las actividades sociales y económicas durante los siglos XIX y XX, antes de la construcción de la ruta nacional Nº 40. Se trata de un conjunto de construcciones, con variable grado de conservación, caracterizadas por una típica arquitectura colonial y postcolonial, entre los cuales se encuentra un molino hidráulico y una vieja casona, ubicada enfrente. Nuestras investigaciones en el área, iniciadas en el año 2017, estuvieron centradas originalmente en el molino, atendiendo a sus aspectos cronológicos y funcionales. No obstante, la posibilidad de que esta casona tuviera algún grado de articulación, por su cercanía y similitudes arquitectónicas, hizo que las pesquisas también incluyeran este edificio. En virtud de esto, en este trabajo presentamos los primeros datos procedentes de la excavación de la casona y su correlación con las excavaciones realizadas en el Molino Harinero de Payogasta. Los primeros resultados permiten confirmar que ambos fueron contemporáneos, si bien la casona habría sido propiedad de sectores sociales vinculados a la propiedad de la tierra, en tanto los dueños del molino estaban más bien relacionados al sector comercial del pueblo, que brindaba el servicio de la molienda. Con esto no se descarta que en momentos previos ambos hayan sido parte de la misma Hacienda, a juzgar por los antecedentes que hay para la región.

La Arqueología Histórica contiene tensiones inherentes a su esfuerzo por estudiar vestigios de sociedades que se ubican en un tiempo considerado arbitrariamente como “histórico”. Considero que el campo disciplinar –si se lo puede aceptar como autónomo- enfrenta algunos dilemas sobre los que se puede reflexionar dada su etapa de desarrollo y expansión actual. Uno de ellos es el vínculo entre arqueología e historiografía; el otro es reconocer la agencia del Estado en la serialidad histórica expresada en la materialidad arqueológica.
FROM CRITICAL THINKING – TO CREATIVITY: STEPS TO UNDERSTANDING

The paper contributes to the study of correlation between critical and creative thinking as the twenty-first century skills vital to succeed and stay competitive in the modern Information Age. The aim of the research is to ground a possibility of facilitating creativity with the help of critical thinking. The concepts of creative thinking and critical thinking are analysed. A synergetic correlation of creativity and critical thinking, with mutual reinforcement of both, is argued. Critical thinking is getting more innovative character, while creativity is raising to a higher level with more realistic results. To investigate the mechanism of reaching a creative result through critical thinking, original Bloom’s taxonomy of educational objectives and learning behaviours was compared with its revised version of 2001. It was highlighted that both versions of the taxonomy presuppose that critical thinking skills complement and reliably enable the creation of innovative ideas and new realities. The revised version recognizes and emphasises the creativeness of the critical thinking and, vice versa, the necessity of critical judgments in creating new products. The relevance of critical thinking skills for the development of creativity was considered with the help of an integrative model of critical and creative thinking proposed by L. Combs, K. Cennamo, and P. Newbill. It illustrates that critical and creative thinking overlap when it goes about the generation and refinement of ideas – at the level of high-order thinking processes, according to B. Bloom’s taxonomy. The article argues that collaboration of critical and creative thinking starts even earlier – namely, at the stage of setting a target for innovation, collecting information, interpreting and applying it – and continues throughout the entire path of constructing an innovative idea, its reflective evaluation and practical implementation. That is, critical thinking ensures self-regulation of creative thinking at all stages of creative activity and serves as a methodological tool of the creative process. It is concluded that application of critical thinking to creativity leads to better-grounded decisions, unbiased attitudes, more innovative solutions and higher quality deliverables.

* tight-binding model and the non-equilibrium Green’s function method. With respect to indirect band-gap systems, doping produces the impurity state in the band gap, and such a state produces resonance with conduction-band states of n-type layers under the electric field. We show that this resonance state works to decrease the tunneling length between valence-band states of p-type layers and conduction-band states of n-type layers and promotes the marked enhancement of tunneling current. As for direct band-gap systems, on the other hand, the N-atom doping not only produces the localized N-atom state in the conduction bands but also reduces the band-gap energy by lowering the conduction-band. We show that the localized N-atom state does not contribute to the tunneling current, while the band-gap reduction shortens the tunneling length a little and slightly increases the tunneling current.
Partial dislocation structures at expansion terminating areas of bar-shaped single Shockley-type stacking faults and basal plane dislocations at the origin in 4H-SiC
Authors: Nishio Johji , Ota Chiharu , Iijima Ryosuke
Published: November 2022

Partial dislocation (PD) combinations near the substrate/epilayer interface and the epilayer surface of 4H-SiC are analyzed for bar-shaped single Shockley-type stacking faults (1SSFs) by plan-view transmission electron microscopy (TEM) with the aid of photoluminescence imaging. Although the PDs are found to have a zigzag structure similar to that found in triangular 1SSF by TEM observation, the combination is thought to be different, consisting of a 30° Si-core + 90° Si-core for the triangular 1SSF and 30° Si-core + 30° C-core for the bar-shaped 1SSF. The features of the basal plane dislocation at the origin are speculated by also identifying the converted threading edge dislocation by additional Burgers vector determination of the PD loop by TEM.
