Permian Remelting and Maturity of Continental Crust Revealed by the Daqing Peraluminous Granitic Batholith, Inner Mongolia
Authors: Li Jialiang , Liu Jingao , Wu Chen , Zhu Di-Cheng
Published: March 2022

The Phanerozoic granites in northeast China bear key information for studying the tectonic evolution and crustal growth or reworking in the Central Asian Orogenic Belt (CAOB). The Daqing granitic batholith widely outcrops as a high-level intrusion in the Xing’an-Mongolia Orogenic Belt, southeastern CAOB. Three types of enclaves in granites have been identified: (1) mafic magmatic enclaves (MMEs), (2) volcanic xenoliths, and (3) biotite-rich enclaves. The batholith is mainly composed of peraluminous biotite granite and granodiorite with SiO2=63.95−69.48 wt.%, A/CNK=1.15−1.27, and 2.54 to 4.30 wt.% of normative corundum. They exhibit remarkable enrichment in large ion lithophile elements (LILEs; K, Rb, Th, and Pb) and depletion in high field strength elements (HFSEs; Nb, Ta, and Ti), P, Eu, and Sr, as well as relatively enriched Sr-Nd isotopes (87Sr/86Sri=0.70530−0.70576, εNdt=–0.1−+0.2). Zircon U-Pb dating suggests that this batholith was emplaced in the Early Permian (ca. 283-282 Ma), consistent with a period of intensive magmatic activities in northern Inner Mongolia. The Nb/Ta ratios of MMEs (17.6-20.1) are higher than those of the host granites (11.4-12.5), together with the reaction rims where biotite crystals cluster around the amphibole cores, suggesting magma mixing between mantle- and crust-derived melts. Zircons from a biotite-rich enclave define a protolith age of ca. 320 Ma and an anatectic age at ca. 281 Ma. Whole-rock Sr-Nd isotopic modelling and zircon Hf isotopes reveal that the batholith was mainly produced by remelting of newly accreted continental crust with minor addition of mantle-derived materials. The geochemical compositions imply that their precursor magmas originated from a relatively high crustal level (<5 kbar) with crystallization temperatures ranging from 800 to 850°C. We suggest that the Daqing peraluminous granitoids were derived from partial melting of newly accreted crustal materials at a relatively shallow crustal depth, associated with a ridge subduction-related heat source. Such mantle-derived magmas through a slab tear window resulting from ridge subduction provide not only the heat for the widespread crustal remelting and therefore maturity but also juvenile materials for crustal growth.

Published: March 2022

Background: Triple-negative breast cancer (TNBC) is a relatively rare subtype of breast cancer, and is prone to lymph node metastasis at early stage. However, there is a lack of prognosis prediction models. The purpose of this study is to develop and validate an effective nomogram for predicting the probability of lymph node metastasis in early-stage TNBC.Methods: We selected 26,775 eligible patients who were diagnosed with early-stage TNBC between 2010 and 2015 from the Surveillance, Epidemiology, and End Results database. All the patients were randomly divided into a training cohort and a validation cohort at a 7:3 ratio. The 266 patients in the validation cohort comprised from the Affiliated Jurong Hospital of Jiangsu University for medical records from January 2011 to August 2020 to identify patients with histologically confirmed early-stage TNBC. The predictive accuracy and identification capability of the nomogram of the clinical prediction model were determined using the concordance index (C-index), receiver operating characteristic curves (ROC), and calibration curves.Results: In all, 27,041 patients were included, with 18,929 patients in the training cohort and 8,112 patients in the validation cohort. Multivariate analysis of the training cohort showed the independent risk factors for lymph node metastasis were age, race, primary site, histological type, grade and tumor size, which were all included in the nomogram. In the training cohort, the nomogram presented robust discrimination, with a C-index of 0.712, which was similar to the C-index of 0.710 in the validation cohort. Consistently, the area under the ROC curve was 0.712 in the training cohort and 0.710 in the validation cohort, which both showed good predictive value for lymph node metastasis risk. The calibration curve showed a better agreement between the nomogram-predicted probability and the actual probability of lymph node metastasis risk.Conclusions: The prognostic nomogram for early-stage TNBC patients constructed here shows good application prospect and can assist clinicians in predicting lymph lode metastasis in early-stage TNBC.

During exercise, muscle contraction increases the level of reactive oxygen species (ROS), which has been acknowledged as key signaling entities in muscle remodeling and to underlie the healthy adaptation of skeletal muscle. ROS inevitably endows damage to genomic DNA of the myofibers, and DNA damage ought to be repaired to ensure the integrity and fidelity of genetic materials; yet, how DNA repair metabolites affect muscle remodeling remains elusive. Here, we demonstrated that exercise induces 8-oxo-7,8-dihydroguanine (8-oxoG) generation in nuclei of myofiber, which subsequently is repaired. In myoblasts, 8-oxoG functions as a signal messenger, triggering myogenic differentiation via activating RAS-MEK-MyoD signal axis. 8-OxoG glycosylae 1 (OGG1) silencing from cells or depletion from mice decreased Ras activation, ERK phosphorylation, MyoD transcriptional activation, myogenic regulatory factors gene (MRFs) expression and consequently myogenic differentiation of myoblasts. Microscale Thermophoresis (MST) assay showed high affinity of 8-OxoG binding with OGG1, the complex functions as guanine nucleotide exchange factor (GEF) to activate Ras. In reconstruction experiments, exogenously added 8-oxoG base increases in the expression of MRFs and accelerates recovery of the injured skeletal muscle. Collectively, these data not only suggest that DNA repair metabolite 8-oxoG function as a signal entity for muscle remodeling and contribute to exercise-induced adaptation of skeletal muscle, but also pave the way for utilizing 8-oxoG in clinical treatment to skeletal muscle damage-related disorders.
Topological and hydraulic metrics-based search space reduction for optimal re-sizing of water distribution networks
Authors: Diao Kegong , Berardi Luigi , Laucelli Daniele B. , Ulanicki Bogumil , Giustolisi Orazio
Published: March 2022

Pipe re-sizing of water distribution networks (WDNs) aims at improving the service performance to the required level, while minimizing the cost of replacing pipes in the network. The main challenge comes from the identification of the most effective pipes to re-size from a large number of interacting components. Performing a global search over all pipes in large WDNs does not guarantee a feasible and efficient solution due to the enormous search space, even by employing advanced algorithms, e.g., evolutionary algorithms. This paper proposes a novel method to reduce the search space for optimal re-sizing based on topological metrics from Complex Network Theory and hydraulic metrics, while providing suboptimal solutions comparable to the full search solutions, i.e., considering all pipes as candidates. The topological metrics are based on the edge-betweenness tailored for WDN analysis. Hydraulic metrics are unit head loss and flow rates of pipes computed based on simulation of the WDN in the current configuration. The optimal re-sizing plans obtained, particularly those using edge betweenness, were tested on a real WDN. The results are comparable with the full search solutions but they are much more efficient to obtain and require replacing mostly contiguous pipes, i.e., easier for practical fieldwork.

BACKGROUND

Delays in the diagnosis of neurodevelopmental disorders (NDDs) in toddlers and postnatal depression (PND) in mothers are major public health issues. In both cases, early intervention is crucial.

OBJECTIVE

We aimed to assess if a mobile app named Malo can reduce delay in the recognition of NDD and PND.

METHODS

We performed an observational, cross-sectional, data-based study in a population of young parents with a minimum of 1 child under 3 years of age at the time of inclusion and using Malo on a regular basis. We included the first 4000 users matching the criteria and agreeing to participate between November 11, 2021, and January 14, 2022. Parents received monthly questionnaires via the app, assessing skills on sociability, hearing, vision, motricity, language of their infants, and possible autism spectrum disorder. Mothers were also requested to answer regular questionnaires regarding PND, from 4-28 weeks after childbirth. When any patient-reported outcomes matched predefined criteria, an in-app notification was sent to the user, recommending the booking of an appointment with their family physician or pediatrician.
The main outcomes were the median age of the infant at the time of notification for possible NDD and the median time of PND notifications after childbirth. One secondary outcome was the relevance of the NDD notification for a consultation as assessed by the physicians.

RESULTS

Among 4242 children assessed by 5309 questionnaires, 613 (14.5%) had at least 1 disorder requiring a consultation. The median age of notification for possible autism spectrum, vision, audition, socialization, language, or motor disorders was 11, 9, 17, 12, 22, and 4 months, respectively. The sensitivity of the alert notifications of suspected NDDs as assessed by the physicians was 100%, and the specificity was 73.5%. Among 907 mothers who completed a PND questionnaire, highly probable PND was detected in 151 (16.6%) mothers, and the median time of detection was 8-12 weeks.

CONCLUSIONS

The algorithm-based alert suggesting NDD was highly sensitive with good specificity as assessed by real-life practitioners. The app was also efficient in the early detection of PND. Our results suggest that the regular use of this multidomain familial smartphone app would permit the early detection of NDD and PND.

The yellow book material is an important component in a dayah (Islamic boarding school). The yellow book learning material is a program developed in the dayah (Islamic boarding school), both salafi and khalafist dayahs. And to carry out the process of planning the yellow book learning material, the dayah needs to make an efficient plan. This study discusses the management of the yellow book learning planning for the third grade students of the MUDI Dayah Great Mosque of Samalanga, Bireuen Regency. So the author examines, first; the yellow book learning material planning system for the third grade students of the MUDI Masjid Raya Samalanga, second grade; planning method for delivering yellow book learning materials for third grade students of the MUDI Dayah Masjid Raya Samalanga, third; planning evaluation of yellow book learning materials for third grade students of the MUDI Dayah Masjid Raya Samalanga. In this study, the author uses a qualitative type of research that is a phenomenological descriptive analysis with a management approach to the planning of the MUDI dayah institution at the Samalanga Grand Mosque. The research subjects were purposively sampling where the interviewees were only the head of the curriculum, the head of the MUDI Mesjid Raya Dayah education sector, the third grade teacher/guardian, and the third grade student. The results of the first research; shows that the planning system for the yellow book learning material for the third grade students of Dayah MUDI Masjid Raya Samalanga is in accordance with the education level of the third grade students. Where the yellow book learning material is clearly visible based on the results of interviews and documentation that already exists and is neatly arranged, the yellow book that is determined is very systematic according to the education level of third grade students. Second, the form of the yellow material delivery planning method for third grade students consists of the syafahi/bandongan method, the sima'ie/sorongan method and the bahsul matsail. Where the three methods are used by the teacher in delivering the yellow book learning material for third grade students at the MUDI Dayah of the Samalanga Grand Mosque. Third, to determine the ability of students to read the yellow book learning material for third grade students at the MUDI Dayah of the Samalanga Grand Mosque, it can be known through evaluation. Planning the evaluation of the yellow book learning material for third grade students at the MUDI dayah in one year is carried out three times in three semesters. In each semester, the evaluation is scheduled for fifteen days with three examiners, each examiner overseeing the exam for five days. Then for the third grade in particular, the evaluation schedule has three additional days to evaluate the material of the Alfiah temple memorizing book with a supervisor teacher who has been determined by the dayah curriculum.

Neoliberalismo mundializado no turismo da Região Nordeste do Brasil: estado de Sergipe em análise
Authors: Rodrigues Larissa Prado , Santos Cristiane Alcântara de Jesus
Published: March 2022

No Brasil, o turismo passou a ser considerado estratégia de desenvolvimento socioeconômico para a região nordeste frente aos altos índices de pobreza, ocasionados em virtude do desenvolvimento regional desigual engendrado ao longo de décadas por políticas desenvolvimentistas. Sob essa perspectiva, os discursos das políticas públicas que promoveram o turismo brasileiro na região anteposta, reforçavam-no como importante ferramenta para a geração de emprego, renda, divisas e desenvolvimento local. A partir dos anos 1990, o turismo passa ser balizado por políticas públicas financiadoras neoliberais que visavam dotar o espaço no nordeste brasileiro de infraestrutura para a atração de investimentos privados estrangeiros. Como resultado, impactos de ordem social e ambiental foram causados para a região, em que os maiores beneficiados por estas intervenções espaciais foram os grupos empresariais que encontraram terreno para ampliar e expandir a reprodução, evasão e acumulação do capital, em detrimento das populações locais. Diante desta complexa conjuntura, a presente pesquisa tem por objetivo captar a influência da ideologia neoliberal mundializada na elaboração de documentos condutivos e normativos para a atividade turística de Sergipe, buscando evidenciar a forma que os paradigmas hegemônicos condutores das ações políticas governamentais têm seus princípios reproduzidos no conteúdo das políticas públicas de turismo na esfera estadual. Metodologicamente, este estudo parte da pesquisa qualitativa e exploratória, juntamente às técnicas de levantamento e revisão bibliográfica e análise documental. Evidenciamos a incapacidade que o turismo, de cunho neoliberal, tem de propiciar o desenvolvimento sustentável, endógeno e local, de dirimir desigualdades regionais e de propiciar melhor qualidade de vida e/ou bem-estar aos residentes.

O presente texto traz uma nova desembocadura para o mar por onde navegamos na pesquisa da dissertação. Essa pesquisa teve como objetivo central o estudo da relação do Turismo com a Geografia, considerando-se o papel do Ensino da Ciência Geográfica na leitura da paisagem e na construção do lugar, principalmente sob o olhar do turista. Empregaram-se os conceitos geográficos e a teoria das representações sociais. O método utilizado foi o da Complexidade com os seus princípios norteadores apontando para leituras provisórias. Aceitando essa provisoriedade, chegamos neste artigo,a outros portos, que compreendem a importância de trabalhar o Turismo na educação formal no Ensino de Geografia. O estudo foi ambientado em Garopaba, município litorâneo do estado de Santa Catarina. Através da pesquisa qualitativa, realizamos entrevistas episódicas com sujeitos turistas, moradores e professores de Geografia, bem como realizamos observações de campo. Notamos que o ensino de Geografia de qualidade, que estuda as paisagens a partir de suas gêneses, favorece a leitura valorativa do patrimônio que compõe os diferentes lugares. Mostrando-se, assim, importante no comportamento dos turistas para com o local visitado e para com os atores locais. Pensamos, neste momento, que, se queremos proteger o local e seus atores, precisamos também redefinir a rota de navegação e ancorar nas escolas locais, a fim de fortificar a educação do Turismo para as comunidades receptoras.
Anticoagulation Therapy in Patients Undergoing Micra Leadless Pacemaker Implantation
Authors: Kadado Anis John , Chalhoub Fadi
Published: March 2022

Over the past decade, there has been significant improvement in the
treatment of diseases of the conduction system and symptomatic
bradyarrhythmias with the development of leadless pacemaker systems. The
Micra transcatheter pacemaker system has been shown to mitigate a lot of
the complications associated with traditional pacing systems, which are
notably skin pocket and lead-related complications. Numerous studies
have shown the low complication rates associated with Micra procedure;
however, there have been no specific guidelines or recommendations
surrounding periprocedural anticoagulant therapy. This is important
because a significant percentage of patients requiring pacemaker therapy
have an indication for anticoagulation therapy as well. Multiple studies
have shown the safety of uninterrupted anticoagulation during Micra
implant, however, there is insufficient high-quality data to recommend
periprocedural systemic use of anticoagulation. In this paper, we review
the available data surrounding anticoagulation therapy in patients
undergoing Micra implantation and the potential bleeding risks
associated with this procedure.
CONSUMER BEHAVIOR OF INHABITANTS OF KALININGRAD DISTRICT IN THE POLISH-RUSSIAN LOCAL BORDER TRAFFIC ZONE
Authors: Batyk Iwona M. , Rakowska Joanna
Published: March 2022

Local Border Traffic (LBT) established on the Polish and Russian border in 2012 created new market opportunities for Russian consumers from the Kaliningrad District, which led to a question of how the changing political, economic and social conditions impacted consumer behavior of Russians in the border market of LBT. The study aimed to answer this question based on a survey of 1,022 respondents from Kaliningrad District, carried out in 2012–2016. Findings show that Russian consumers benefitted from cross-border shopping and trade and contributed to local development on both sides of the border until administrative and economic barriers appeared. The unfavorable border crossing regulations, ban on the import of agri-food goods from Poland to the Russian Federation, and increasingly unfavorable ruble exchange rates changed the behavior of Russian consumers significantly, decreasing their purchase and consumption of goods and services bought in the LBT zone in Poland.

Authors: Łączkowska Martyna , Borychowski Michał
Published: March 2022

Photovoltaics is increasingly used to convert solar energy into electricity in households, including in Poland. The development of this type of renewable energy results, on the one hand, from legal regulations related to climate and energy policies, and on the other hand, from the numerous benefits connected with the use of photovoltaics. These include both economic and environmental advantages. The aim of the work was to assess the profitability of installing photovoltaics in a Polish household in 2019–2021. Therefore, the costs of the investment are presented, as well as the benefits, mainly in economic terms. Different calculations and estimates concerning return on the invested capital are also shown. During the 31 months covered by the study, the cumulative positive balance of electricity that was generated above the energy consumed in the household exceeded 2,900 kWh, which resulted in an economic surplus of over PLN 1,600 (about EUR 360). What is more, the investment contributed to the protection of the natural environment which is the added value of the photovoltaics.

Published: March 2022

Las Tecnologías de la Información y la Comunicación (TIC) han sido clave para que la enseñanza en línea ingresara con tal ímpetu en el mundo pedagógico que modificara el paradigma educativo. La oferta y demanda de cursos en línea se ha incrementado fuertemente los últimos años debido principalmente a dos parámetros: su menor costo con respecto a cursos tradicionales, y la necesidad de distanciamiento social en tiempos de contingencia. Sin embargo, poco se sabe aún sobre la deseada equivalencia en la eficacia académica entre la opción en línea y la presencial. En este trabajo se comparan ambas modalidades a través de los resultados obtenidos en los cursos de ingreso presencial y en línea dados a aspirantes al programa de la Licenciatura Ingeniería en Computación de la Universidad Autónoma de Zacatecas. Los cursos fueron diseñados de manera que se minimizaran las diferencias entre ellos, siendo la variable clave la modalidad en línea o presencial. El análisis estadístico no muestra diferencias significativas, por lo que se concluye que ambas modalidades son equivalentes para este estudio de caso.

Authors: Chura Quispe Gilber , Chávez Guillén Julisa Yrelsa , Leyva Ato Lady Antuanette
Published: March 2022

El Flipped Classroom (FC) es un modelo educativo que invierte las tareas de casa y aula para brindar más espacio al aprendizaje activo en las sesiones sincrónicas mediante la combinación de estrategias flexibles y herramientas digitales. El estudio presenta una revisión sistemática de investigaciones empíricas sobre FC en la formación de profesionales de ciencias fácticas (culturales). La revisión se fundamenta en los indicadores de calidad que sostiene PRISMA con una muestra de 55 artículos de investigación seleccionados con criterios de inclusión y exclusión de las bases de datos Scopus y Web of Science sobre el FC en estudiantes universitarios del campo de las ciencias fácticas entre los años 2016-2020. Los estudios analizados muestran significancia del FC en los estudiantes, así como una actitud, motivación y satisfacción positiva. El modelo se ajusta a otras estrategias de enseñanza-aprendizaje mediante la participación tecnológica y pedagógica. Las limitaciones refieren al tamaño de muestra, duración de la intervención y falta de validación de instrumentos de medición y programas de aplicación. En conclusión, el FC genera un efecto positivo de las propuestas a nivel académico y motivacional para la formación de profesionales en las ciencias fácticas. Se propone cuatro futuras líneas de investigación para este modelo.

Binary mixtures containing imidazolium ionic liquids: properties measurement
Authors: Steltenpohl Pavol , Graczová Elena
Published: March 2022

Densities and transport properties (dynamic viscosity) of pure imidazolium ionic liquids 1-butyl-3-methylimidazolium acetate and 1-butyl-3-methylimidazolium dicyanamide and their binary mixtures with water and ethanol were measured within the temperature range of 293.15—333.15 K. Obtained experimental data were used to calculate excess molar volume and viscosity deviation. For the chosen binary mixtures, variations of excess molar volume, partial molar volumes of mixture components and of the viscosity deviation with the binary mixture composition were correlated using the Redlich-Kister equation. In addition, variation of viscosity with the binary mixture composition and temperature was fitted using the Jouyban-Acree model.
Linear Motion Error Evaluation of Open-Loop CNC Milling Using a Laser Interferometer
Authors: Winarno Agustinus , Prayoga Benidiktus T. , Hendaryanto Ignatius A.
Published: March 2022

The usage of computerised numerical control (CNC) machines requires accuracy verification to ensure the high accuracy of the processed products. This paper introduces an accuracy verification method of an open-loop CNC milling machine using a fringe counting of He–Ne laser interferometry to evaluate the best possible accuracy and functionality. The linear motion accuracy of open-loop CNC milling was evaluated based on the number of pulses from the controller against the actual displacement measured by the He–Ne fringe-counting method. Interval distances between two pulses are also precisely measured using the He–Ne interferometry. The linear motion error and controller error can be simultaneously evaluated in sub-micro accuracy. The linear positioning error due to the micro-stepping driver accuracy of the mini-CNC milling machine was measured with the expanded uncertainty of measurement and was estimated at 240 nm. The experimental results show that linear motion error of the open-loop CNC milling can reach up to 50 μm for 200 mm translation length.
Bearing Fault Detection and Diagnosis Based on Densely Connected Convolutional Networks

Rotating machines are widely used in today’s world. As these machines perform the biggest tasks in industries, faults are naturally observed on their components. For most rotating machines such as wind turbine, bearing is one of critical components. To reduce failure rate and increase working life of rotating machinery it is important to detect and diagnose early faults in this most vulnerable part. In the recent past, technologies based on computational intelligence, including machine learning (ML) and deep learning (DL), have been efficiently used for detection and diagnosis of bearing faults. However, DL algorithms are being increasingly favoured day by day because of their advantages of automatically extracting features from training data. Despite this, in DL, adding neural layers reduces the training accuracy and the vanishing gradient problem arises. DL algorithms based on convolutional neural networks (CNN) such as DenseNet have proved to be quite efficient in solving this kind of problem. In this paper, a transfer learning consisting of fine-tuning DenseNet-121 top layers is proposed to make this classifier more robust and efficient. Then, a new intelligent model inspired by DenseNet-121 is designed and used for detecting and diagnosing bearing faults. Continuous wavelet transform is applied to enhance the dataset. Experimental results obtained from analyses employing the Case Western Reserve University (CWRU) bearing dataset show that the proposed model has higher diagnostic performance, with 98% average accuracy and less complexity.
Wireless inertial sensor system for hammer throwing
Authors: Tiedemann Stefan , Spelly Gwen , Witte Kerstin
Published: March 2022

The aim of this study is to integrate an inertial sensor inside a hammer to allow a realtime feedback. In the first step we build our own prototype to measure the radial acceleration. In the second step there is a validation with an infrared camera system. It is a comparison between the radial acceleration along the wire axis, that is measured by the sensor against the velocity that is delivered by the infrared camera system. As a result, significant correlation was observed between the measured velocity and the acceleration (r = 0.99, p < 0.001). These suggest that this system can used in the training to improve the technique of the hammer throw.
