Competitive Drivers of Atrial Fibrillation: The Interplay Between Focal Drivers and Multiwavelet Reentry
Authors: Carrick Richard T. , Benson Bryce E. , Bates Oliver R. J. , Spector Peter S. 
Published: March 2021

BackgroundThere is debate whether human atrial fibrillation is driven by focal drivers or multiwavelet reentry. We propose that the changing activation sequences surrounding a focal driver can at times self-sustain in the absence of that driver. Further, the relationship between focal drivers and surrounding chaotic activation is bidirectional; focal drivers can generate chaotic activation, which may affect the dynamics of focal drivers.Methods and ResultsIn a propagation model, we generated tissues that support structural micro-reentry and moving functional reentrant circuits. We qualitatively assessed (1) the tissue’s ability to support self-sustaining fibrillation after elimination of the focal driver, (2) the impact that structural-reentrant substrate has on the duration of fibrillation, the impact that micro-reentrant (3) frequency, (4) excitable gap, and (5) exposure to surrounding fibrillation have on micro-reentry in the setting of chaotic activation, and finally the likelihood fibrillation will end in structural reentry based on (6) the distance between and (7) the relative lengths of an ablated tissue’s inner and outer boundaries. We found (1) focal drivers produced chaotic activation when waves encountered heterogeneous refractoriness; chaotic activation could then repeatedly initiate and terminate micro-reentry. Perpetuation of fibrillation following elimination of micro-reentry was predicted by tissue properties. (2) Duration of fibrillation was increased by the presence of a structural micro-reentrant substrate only when surrounding tissue had a low propensity to support self-sustaining chaotic activation. Likelihood of micro-reentry around the structural reentrant substrate increased as (3) the frequency of structural reentry increased relative to the frequency of fibrillation in the surrounding tissue, (4) the excitable gap of micro-reentry increased, and (5) the exposure of the structural circuit to the surrounding tissue decreased. Likelihood of organized tachycardia following termination of fibrillation increased with (6) decreasing distance and (7) disparity of size between focal obstacle and external boundary.ConclusionFocal drivers such as structural micro-reentry and the chaotic activation they produce are continuously interacting with one another. In order to accurately describe cardiac tissue’s propensity to support fibrillation, the relative characteristics of both stationary and moving drivers must be taken into account.

A relação família-escola é tida, na perspetiva de professores e pais/encarregados de educação, como fundamental para o rendimento académico dos alunos e sucesso das instituições escolares, influenciando, ainda, as tomadas de decisão na gestão da escola. Porém, a sua não efetivação prática, tem sido caracterizada muitas vezes, por atribuição de culpa entre professores e encarregados de educação. Os professores culpam os pais de falta de interesse e instrução suficiente sobre como participar das atividades da vida escolar dos filhos e os pais culpam a escola de não estar preparada para a inserção da família em atividades de âmbito educativo no contexto escolar. Pretendemos analisar as perceções de professores e pais/encarregados de educação, no que tange à problemática da relação família-escola, no contexto de uma escola pública do ensino primário, primeiro e segundo ciclos do ensino secundário em Angola. Foi desenvolvido uma investigação qualitativa, com base num caso naturalista. De acordo com os resultados das entrevistas feitas aos pais e professores, conclui-se que o envolvimento da família nas ações da escola, e seu acompanhamento da escolarização dos filhos, bem como a participação da família na tomada de decisão, é considerada fundamental, contribuindo para o bom funcionamento das instituições escolares

The goal of the paper is to study the activity of the party archives of the Communist Party of Ukraine (the CPU) in 1960-1980, aimed at creating sets of documents about the Second World War - the documents of personal origin and thematic collections; to determine the main principles that guided the archival institutions while conducting the selection of fund-forming agents and documents which in their opinion were supposed to adequately reflect the Second World War events; to characterize the directions of search, archeographic and publishing work of Soviet archivists; to analyse the information content, completeness, and reliability of the created sets of documents, the consequences of the party archives' activity for the historical memory of the Second World War events. Research methodology. In the course of the research, general scientific and specific historical methods of source and archival heuristics, scientific criticism of sources, diplomatic, textual, and hermeneutical analysis were used. Scientific novelty. The paper introduces the previously unpublished documents on the history of party archives into scientific discourse and reveals the technologies for falsifying the Second World War history at the level of archival institutions during the specified period.Conclusions. In the course of the research, it was found out that the document collections were made in violation of the principles of archival science, which led to the shaping of the Soviet myth of the Great Patriotic War. However, as a result of their activities, the archivists accumulated a lot of interesting historical material, which was not made public due to ideological principles and it creates a certain field for contemporary studies on the history of the Second World War.

The percentage of toddlers who are very short and short of age 0-59 months in Indonesia in 2018 is 11.5% and 19.3%. This condition increased from the previous year, namely the percentage of toddlers aged 0-59 months was very short at 9.8% and short toddlers at 19.8%. In the Special Region of Yogyakarta the incidence of stunting is also still quite high at 27.2%. In Sleman Regency the prevalence of nutritional status of toddlers was short and very short in 2017 an increase of 0.18% compared to 2016, from 11.81% to 11.99%. One of the factors causing Stunting in Sleman Regency is the lack of parental knowledge about giving the right complementary feeding, which causes toddlers to get less optimal nutrition. Identification of problems in depth such as difficulty in breastfeeding, reduced breastmilk syndrome, toddlers who are picky eater have not been done optimally and comprehensively. In addition, from the pre-test results conducted before educational activities, there were 56% of mothers under-five who did not understand the right complementary feeding for their children, most parents gave instant complementary feeding and bought complementary feedingin the market or baby porridge sales outlets. The activity was attended by 25 mothers who had children under the age of 24 months. To measure the success of this activity, pre-test and post-test were carried out. The result of devotion is that after participating in complementary feeding educational activities the level of knowledge of mothers about complementary feedinghas increased, before participating in the activity the number of mothers who have a high level of knowledge only 4% after participating in the activity increased to 44%. With increasing knowledge about complementary feedingit is expected that mothers can apply their knowledge in providing home made complementary feedingwith local materials that are in accordance with WHO and Unicef recommendations.Keywords: education, complementary feeding, home made

The development of information technology has brought changes in almost all aspects of human life. In the world of education improving the quality of teachers is something that must be done by the education unit, especially improving the skills of teachers in making information technology-based learning media. The aim is to improve the quality of learning processes and outcomes in schools. From the results of an interview with one of the teachers at SMPN 4 Karangmoncol Purbalingga, they have not maximized information technology to be used as a learning medium. They still use manual learning in class (calcical) so that one of the problems when the teacher has a meeting or need, the class becomes empty there is no teaching and learning process. Based on this, we are from community service trying to provide assistance in activities to improve the skills of teachers of SMPN 4 Karangmoncol in making information technology-based learning media. This training program can meet the needs of the community (teachers) in the scope of Karangmoncol Middle School 4 in order to improve the quality of teachers in Karangmoncol Middle School 4, especially in making information technology-based learning media. This training program is also carried out in order to succeed the government program for teachers so that they are literate in technology and apply it in the learning process which results in the effectiveness of achieving learning objectives.

Non-volatile memory system design of edge server and cloud centralized server for multiple-tier 5G network
Authors: Matsui Chihiro , Takeuchi Ken 
Published: March 2021

Abstract
This paper co-designs a network and non-volatile memory system for a fifth generation (5G) multiple-tier network. Because a 5G network has shorter latency and wider bandwidth compared with a 4G network, the non-volatile memory system becomes a bottleneck. From the bottom to the top of the multiple-tier network, edge devices/machines, edge servers, and cloud centralized servers play different types of roles and handle different types of data. Thus, different types of non-volatile memory are required for cloud centralized servers, edge servers, and edge devices/machines. This work employs three-dimensional single-level cell (3D-SLC) NAND flash memory for edge servers and resistive RAM (ReRAM) for cloud centralized servers. To achieve short latency and low cost of the non-volatile memory system, distributed multiple write for 3D-SLC NAND flash memory and hierarchical multiple-deck ReRAM are proposed. By using an evaluation platform of the network and non-volatile memory co-design system, the proposed non-volatile memory system is defined as a network bottleneck or memory bottleneck.
Mechanism for ultrasonic pitting of starch particles
Authors: Sugino Fumiya , Yamamoto Ken 
Published: March 2021

Abstract
In this study, the ultrasonic pitting of microscopic particles is investigated using ultrasound with frequencies from 26 kHz to 3.6 MHz. With increasing ultrasonic frequency, the number of pits formed on the surfaces of the microscopic particles increases initially but then decreases, and these changes in the number of pits are attributed to the relationship between the cavitation bubbles and the size of the object, and to the stress generated. Also confirmed is that adding a surfactant affects the ultrasonic pitting, with that effect differing with the surfactant concentration and the ultrasonic frequency. The results suggest that the number of pits depends on the size distribution of the cavitation bubbles and the distance between the bubble and the object. Overall, it is concluded that the important parameters in ultrasonic pitting are (i) the size relationship between the cavitation bubble and the object, (ii) the physical characteristics of the object, and (iii) the distance between the bubble and the object.
Development of a high-speed, phase-sensitive laser probe system for RF surface acoustic wave/bulk acoustic wave devices with an absolute vibration amplitude measurement function
Authors: Takahashi Hikaru , Omori Tatsuya , Hashimoto Ken-ya 
Published: March 2021

Abstract
This paper describes the coaxial integration of a Michelson interferometer (MI) and a Sagnac interferometer (SI) in a high-speed, phase-sensitive laser probe for surface acoustic wave/bulk acoustic wave devices. This combination enables the MI to be used for calibration of the vibration amplitude captured by the SI without sacrificing the measurement accuracy and speed of the SI-based laser probe. First, the system setup is detailed. Next, simultaneous measurement is performed using the SI and MI, and good coincidence is demonstrated between these measured results after correction of tiny misalignment between two optical axes. This means that the calibration can be performed simply by multiplying the data captured by SI by a coefficient of proportionality; this value of this can be determined by comparison with the data captured by simultaneous measurement for a tiny area. Finally, the procedure for absolute vibration amplitude measurement is proposed and its validity is confirmed by actual measurement.

Abstract
New high-speed photonic technologies and co-integration with electronics are required to keep up with the demand of future optical communication systems. In this paper, plasmonics is presented as one of the most promising next-generation photonic technologies that already fulfils these requirements in proof-of-concept demonstrations. Plasmonics features not only modulators and detectors of highest speed, but also compactness, cost- and energy-efficiency, and compatibility with CMOS electronics. Recently, co-integration with electronics was demonstrated with record performances of 222 GBd in a hybrid InP electronic-plasmonic transmitter assembly and of 120 GBd with a monolithic BiCMOS electronic-plasmonic transmitter.

В настоящее время наблюдается дефицит отечественных специализированных продуктов питания на потребительском рынке региона Кузбасс, в том числе продуктов, не содержащих глютен, что определяет необходимость расширения их ассортимента, разработки инновационных технологий производства, оценки качества и безопасности. Аглютеновые продукты питания (продукты, не содержащие в своем составе глютен) занимают один из сегментов этого рынка. Актуальность разработки безглютеновых (БГ) продуктов не вызывает сомнений, так как количество людей с непереносимостью глютена возрастает ежегодно и удовлетворение потребительского спроса является важной задачей. Также среди основных задач находится не только разработка рецептур смесей, но и подбор технологических режимов и параметров их получения для практической реализации результатов в промышленном производстве. В статье приведены результаты исследований по получению однородной безглютеновой мучной смеси на барабанном смесителе непрерывного действия. Мучная смесь предназначена для производства мучных кондитерских изделий, не содержащих в своем составе глютен. Для экспериментального исследования процесса смешивания безглютеновой смеси был выбран барабанный смеситель непрерывного действия с гладкой внутренней поверхностью барабана, без дополнительных перемешивающих устройств, и определены рациональные параметрами работы смесителя. Значения показателей, описывающих неоднородность смеси получены с применением кондуктометрического метода химического анализа. Полученные результаты показали, что лучшее качество получаемой безглютеновой мучной смеси достигается при частоте вращения барабана 10 мин-1 и его коэффициенте заполнения 30%. Обработка результатов исследований проводилась с помощью методов множественной регрессии. Полученная регрессионная модель с достаточной точностью может применяться для предсказания качества получаемой БГ мучной смеси, поскольку среднее значение ее относительной погрешности не превышало 10 %.
