Authors: Kovtun P. V. , Dubrovskaya T. A. , Tsarikov V. A.
Published: June 2023

The track economy is the most important branch of the republic's railway transport, on the state of which the robotic capacity of the entire railway depends. The normal functioning of the track facilities is impossible without the use of modern resource-saving technologies, high-performance and modern technology, without the regular provision of materials for the repair and maintenance of the track. The purpose of the article is to analyze the state of the track and its main elements. The main task is to ensure the safety of train traffic. As shown by the safety analysis in 2020, 9 events were admitted related to the violation of traffic safety rules and the operation of railway transport. To ensure the safety of train traffic, it is necessary to study a number of issues on the maintenance of continuous-welded rail strings, including avoiding lateral wear by re-laying them, reducing the number of defective rails, including through the introduction of aluminothermic welding and surfacing of rails. In 2020, due to the implementation of the repair program and according to the actual state of the track, train speeds were increased by almost 350 km. In order to further strengthen the track facilities of the Belarusian Railway, ensure the safety of train traffic and increase the efficiency of planning of labor and material resources, in 2020, the Program for the repair of railway tracks of the Belarusian Railway for 2021 - 2023 was developed. The implementation of the Program for the repair of railway tracks of the Belarusian Railways for 2021 - 2023 will allow to exclude kilometers of railway tracks with overdue repairs available as of 01.01.2021 and prevent an increase in their number in subsequent years.

Authors: Nuñez Espinel Luz Angela
Published: June 2023

Objetivo: analizar la experiencia de los estudiantes de las universidades públicas de Bogotá con el modelo de educación remota de emergencia implementado a raíz de la suspensión de las clases presenciales por la pandemia de COVID-19.

Originalidad/aporte: Su enfoque, centrado en las experiencias de los estudiantes, provee un acervo de información sobre los actores centrales del proceso educativo, evidenciando algunas brechas entre el discurso y la realidad de la educación remota. 

Método: mixto, en cuanto integra información cualitativa y cuantitativa. Las preguntas cerradas fueron procesadas estadísticamente y sus resultados se contrastaron con la información obtenida en las preguntas abiertas y con la literatura sobre el tema.  

Estrategias/recolección de información: Como instrumento básico para la recolección de información se utilizó una encuesta virtual sobre las condiciones de conectividad y la experiencia de los estudiantes bajo el modelo de educación remota, aplicada en cuatro universidades públicas de Bogotá, entre octubre y noviembre de 2020.

Conclusiones:Los principales hallazgos se orientan en tres direcciones: en primer lugar, se confirma que la necesidad de acceder a un equipo de manera permanente, con conexión de calidad a internet, constituye un obstáculo de difícil solución para los estudiantes, que genera frustración y desmotivación. En segundo lugar, se evidencia que, para los estudiantes, la conexión a internet y el entorno doméstico son percibidos como fuente de distracción de sus estudios. En tercer lugar, como consecuencia de las dos anteriores, los estudiantes mayoritariamente consideran que la calidad de la educación ha disminuido y creen que esto impactará negativamente su futuro profesional.

CAMPSTER E-LEARNING PLATFORM: ADDITIONAL RESOURCE MATERIAL IN ROMANIAN LANGUAGE TEACHING. A CASE STUDY
Authors: Ivanić Ivana D. , Ranitović Ana G. , Nimigean Gina I.
Published: June 2023

The use of new technologies in language teaching has a positive effect both on the teaching process itself and on the motivation of students. Today’s students are not satisfied with the teaching material they use in class, they need additional support and motivation, additional engagement within their field of interest, which is the digital world. If we offer them appropriate platforms, applications and opportunities for their improvement outside of institutional learning (which is the basis for any further advancement), it is possible to achieve exceptional results. The aim of the paper is to examine students’ attitudes about the use of additional materials in Romanian as a foreign language teaching both in Serbia and Romania, at the University of Novi Sad and the “Alexandru Ioan Cuza” University of Iași. In the course of the winter semester of the academic year 2021/2022, students used the Campster platform and the courses on it, which were free to use. Two groups of students, one from each country, participated in the survey of students’ attitudes.
Gereformeerde pietisme, neoplatonisme en pre-Romantieke teodisee in die Voortrekkervrou Susanna Smit (1799-1863) se godsdienstige dagboeke
Authors: Raath Andries
Published: June 2023

The first half of the eighteenth century witnessed a resurgence of Platonism in literature generally and in theology in Germany en Holland in particular, because of the appeal Plato’s ideas held for the distinction between immanent and transcendental reality, man’s quest for unity with the Good, and the human soul as the vehicle for uniting with God. Because most human beings are preoccupied with material things, Plato believed they need to have their thoughts turned to the immaterial reality behind the material world, and thus to be weaned away from the objects of their passions. To Plato the world is more than a world of appearances. Behind each particular thing is the idea or form of the thing. Moreover, the ideas or forms are all ultimately related to the Form of the Good. Plato believed that the soul is an immaterial entity, which in some ways is like the Forms. Particularly revealing to the emerging trend of Romanticism was Plato’s philosophical transcending of sceptical and materialistic views of reality, the notion that those who know what is good will love and desire it, and that moral virtue is of itself a prerequisite to knowing the good. The problem presented itself as to how sinful man and chaos in the world can be brought in accordance with God’s perfect and sinless nature. Because Plato’s view of human improvement by means of education and salvation through personal virtue is far removed from the Christian message of redemption by a loving, personal God, Pietists reverted to the neo-Platonism legacy of love mysticism to resolve the dualism inherent to the Romantic juxtaposition of the immanent and the transcendent. The Voortrekker woman Susanna Smit reflected these influences in her Reformed Pietistic spirituality and re-interpreted the Christian conviction of the love of God and man’s salvation by relying on neo-Platonism love spirituality in the works of James Hervey, Rutger Schutte, Hieronymus van Alphen, Rhijnvis Feith and other pietistically inclined authors. This research investigates the impact of the idea of experiential numinous love mediating between the Good and the human soul and neo-Platonism love sentimentality in Susanna Smit’s diaries and the effect of these influences in her Reformed Pietistic spirituality from 1843 to 1863.

Published: June 2023

Introduction: Neurocutaneous syndromes (NCS) are a heterogeneous group of conditions with multiorgan involvement and diverse manifestations, evolving throughout life with significant morbidity. A multidisciplinary approach to NCS patients has been advocated, although a specific model is not yet established. The aim of this study was 1) to describe the organization of the recently created Multidisciplinary Outpatient Clinic of Neurocutaneous Diseases (MOCND) at a Portuguese pediatric tertiary hospital; 2) to share our institutional experience focusing on the most common conditions, neurofibromatosis type 1 (NF1) and tuberous sclerosis complex (TSC); 3) to analyze the advantages of a multidisciplinary center and approach in NCS.Methods: Retrospective analysis of 281 patients enrolled in the MOCND over the first five years of activity (October 2016 to December 2021), reviewing genetics, family history, clinical features, complications, and therapeutic strategies for NF1 and TSC.Results: The clinic works weekly with a core team of pediatricians and pediatric neurologists supported by other specialties as needed. Of the 281 patients enrolled, 224 (79.7%) had identifiable syndromes such as NF1 (n = 105), TSC (n = 35), hypomelanosis of Ito (n = 11), Sturge-Weber syndrome (n = 5), and others. In NF1 patients, 41.0% had a positive family history, all manifested café-au-lait macules, 38.1% neurofibromas with 45.0% being large plexiformneurofibromas. Sixteen were under treatment with selumetinib. Genetic testing was performed in 82.9% of TSC patients with pathogenic variants found in TSC2 gene in 72.4% patients (82.7% if considered contiguous gene syndrome). Family history was positive in 31.4%. All TSC patients presented hypomelanotic macules and fulfilled diagnostic criteria. Fourteen patients were being treated with mTOR inhibitors.Conclusion: Offering a systematic and multidisciplinary approach to NCS patients enables timely diagnosis, promotes a structured follow-up, and encourages discussion to outline management plans for optimal care to every patient, with significant impact on the quality of life of patients and families.
Item-Oriented Personalized LDP for Discrete Distribution Estimation
Authors: Li Xin , Zhu Hong , Zhang Zhiqiang , Xie Meiyi
Published: June 2023

Discrete distribution estimation is a fundamental statistical tool, which is widely used to perform data analysis tasks in various applications involving sensitive personal information. Due to privacy concerns, individuals may not always provide their raw information, which leads to unpredictable biases in the final results of estimated distribution. Local Differential Privacy (LDP) is an advanced technique for privacy protection of discrete distribution estimation. Currently, typical LDP mechanisms provide same protection for all items in the domain, which imposes unnecessary perturbation on less sensitive items and thus degrades the utility of final results. Although, several recent works try to alleviate this problem, the utility can be further improved. In this paper, we propose a novel notion called Item-Oriented Personalized LDP (IPLDP), which independently perturbs different items with different privacy budgets to achieve personalized privacy protection. Furthermore, to satisfy IPLDP, we propose the Item-Oriented Personalized Randomized Response (IPRR) based on the observation that the sensitivity of data shows an inverse relationship with the population size of respective individuals. Theoretical analysis and experimental results demonstrate that our method can provide fine-grained privacy protection and improve data utility simultaneously.
Component Criticality Analysis for Improved Ship Machinery Reliability
Authors: Daya Abdullahi Abdulkarim , Lazakis Iraklis
Published: June 2023

Redundancy in ship systems is provided to ensure operational resilience through equipment backups which ensures system availability and offline repairs of machinery. The electric power generation system of ships provides the most utility of all systems, hence is provided with good level of standby units to ensure reliable operations. Nonetheless, the occurrence of undesired black outs are common onboard ships and portends a serious danger to ship security and safety. Therefore, understanding the contributing factors affecting system reliability through component criticality analysis is essential to ensure a more robust maintenance and support platform for efficient ship operations. In this regard hybrid reliability and fault detection analysis were conducted to establish component criticality and related fault conditions. A case study was conducted on a ship power generation system consisting of 4 marine diesel power generation plants onboard an Offshore Patrol Vessel (OPV). Results from the reliability analysis indicate overall low system reliability of less than 70 per cent within the first 24 months of the 78 operational months. Component criticality using reliability importance measures was used to identify all components with more than 40 per cent contribution to sub systems failure. Additionally, machine learning was used to aid the reliability analysis through feature engineering and fault identification using Artificial Neural Networks classification. The ANN has identified failure patten threshold at about 200kva which can be attributed to overheating, hence establishing link between component failure and generator performance.
Large Eddy Simulation Inflow Generation Using Reduced Length Scales for Low-Rise Buildings
Authors: Shahrokhi Ava , Berthaut-Gerentes Julien , Ma Lin , Ingham Derek , Pourkashanian Mohamed
Published: June 2023

When undertaking wind assessment around buildings using large eddy simulation (LES), the implementation of the integral length scale at the inlet for inflow generation is controversial, as real atmospheric length scales require huge computational domains. While length scales significantly influence inflow generation in the domain, their effect on the downstream flow field has not yet, been investigated. In this paper, we validate the effectiveness and accuracy of implementing a reduced turbulence integral length scale for inflow generation in LES results at the rooftop of low-rise buildings and develop a technique to estimate the real local length scales using simulation results. We measure the wind locally and calculate the turbulence length scales from the energy spectrum of the wind data and simulation data. According to these results, there is an excellent agreement between the length scale from simulation and measurement when they are scaled with their corresponding freestream/inlet value. These results indicate that a reduced integral length scale can be safely used for LES to provide a reliable prediction of the energy spectrum as well as the length scales around complex geometries. The simulation results were confidently employed to obtain the best location for a wind turbine installation on low-rise buildings.
Flowered Grain Quality and Phytochemical Content of Non-Conventional Maize Hybrids from the Mexican Subtropics in Three Crop Cycles
Authors: García-Cruz Leticia , Vázquez-Carrillo María Gricelda , Preciado-Ortiz Ricardo Ernesto
Published: June 2023

Development of non-conventional hybrids (NCHs) responds to the demand for the Elotes Occidentales 'EO' race for production of pozole. The effect of: crop cycle (2019, 2020 and 2021) on physical characteristics, flowered grain quality and phytochemical content of two HNC (Pz1 and Pz2) of pozolero maize, as well as the effect of the presence or absence of pedicel, type of pollination (open and controlled, 2019), and progenitor lines (female and male, 2020) on flowered grain quality and content of phytochemical compounds were evaluated. Size, hardness, color, total phenols and anthocyanins in unprocessed grain were determined, and yield, volume and puncture strength in flowered grain. Results were analyzed with a factorial arrangement in a completely randomized design. There were significant differences (p≤0.05) in most of the variables studied by effect of crop cycle and genotype. NCHs had large grains (40 g 100 grains-1), soft endosperm (IF> 60), pink-purple color, and phenol and anthocyanin contents similar to those reported for the 'EO' race. The presence or absence of the pedicel did not affect flowered grain quality. Controlled pollination favored anthocyanin synthesis. The anthocyanin content of NCHs was determined by the female line. Thermal processing reduced anthocyanins by 60%; however, they leached into the flowering broth, so that the pozole made from NCHs improves the nutraceutical value of the pozole, relative to that of pozole made with Cacahuacintle maize.
Development of Clause Complexity in Children with Specific Language Impairment/Language Development Disorder. A Longitudinal Study
Authors: Araya Claudia , Coloma Carmen Julia , Quezada Camilo , Benavente Paula
Published: June 2023

This paper addresses the grammatical challenges associated with the development of clause complexity, focusing on the performance of a group of monolingual Spanish-speaking schoolchildren with Specific Language Impairment/Developmental Language Disorder (SLI/DLD) in a longitudinal corpus of oral narrative samples. The study examines the presence of interclause relations of subordination and equivalence (hypotaxis and parataxis) in language samples of two groups: an experimental group made up of 24 schoolchildren with SLI/DLD and a control group made up of 24 schoolchildren with typical development (TD). The results show that while both groups use parataxis as the most common relation between clauses in all school grades, there is a significant decrease in paratactic relations and a significant increase in hypotactic relations from first to fourth grade of primary education. Although the development patterns are highly similar, the SLI/DLD group shows greater difficulties in mastering more complex (hypotactic) relations in fourth grade compared to the control group, indicating that they are less sophisticated in the use of these types of complex relations. These findings suggest that focused support on the most complex structures is needed towards the fourth grade of primary education, given the demands of the school academic register from 6 and 7 years of age, and the potential problems that the development of clause complexity can cause in school-age children.
Enhanced Energy Storage Performance and Efficiency in Bi0.5(Na0.8K0.2)0.5TiO3–Bi0.2Sr0.7TiO3 Relaxor Ferroelectric Ceramics via Domain Engineering
Authors: Pattipaka Srinivas , Choi Hyunsu , Lim Yeseul , Park Kwi-Il , Chung Kyeongwoon , Hwang And Geon Tae
Published: June 2023

In this work, we report the electric energy storage properties of (1-x)Bi0.5(Na0.8K0.2)0.5TiO3-xBi0.2Sr0.7TiO3 (BNKT-BST; x = 0.15-0.50) relaxor ferroelectric ceramics enhanced via a domain engineering method. A rhombohedral–tetragonal phase, the formation of highly dynamic PNRs, and a dense microstructure are confirmed from XRD, Raman vibrational spectra, and microscopic investigations. The relative dielectric permittivity (2664 at 1 kHz) and loss factor (0.058) were gradually improved with BST (x=0.45). The incorporation of BST into BNKT can disturb the long-range ferroelectric order, lowering the dielectric maximum temperature Tm and inducing the formation of highly dynamic polar nano-regions. In addition, the Tm shifts toward high temperature with frequency and a diffuse phase transition, indicating relaxor ferroelectric characteristics of BNKT-BST ceramics, which is confirmed by the modified Curie Weiss law (γ=1.83). The rhombohedral–tetragonal phase, fine grain size, and lowered Tm with relaxor properties synergistically contribute to a high recoverable energy density Wrec of 0.81 J/cm3 and a high energy efficiency η of 86.95% at 90 kV/cm for x = 0.45.
Nanoparticle Size and Heat Pipe Angle Impact on Thermal Effectiveness of a Cylindrical Screen Mesh Heat Pipe.
Authors: Dhairiyasamy Ratchagaraja
Published: June 2023

This study examines the effects of particle size and heat pipe angle on the thermal effectiveness of a cylindrical screen mesh heat pipe using silver nanoparticles as the test substance. The experiment investigates three different particle sizes (30nm, 50nm, and 80nm) and four different heat pipe angles (0°, 45°, 60°, and 90°) on the heat transmission characteristics of the heat pipe. The results show that the thermal conductivity of the heat pipe increased with an increase in heat pipe angle for all particle sizes, with the highest thermal conductivity attained at a 90° heat pipe angle. Furthermore, the thermal resistance of the heat pipe decreased as the particle size decreased for all heat pipe angles. The thermal conductivity measurements of the particle sizes - 30, 50, and 80 nm - were 250 W/mK, 200 W/mK, and 150 W/mK, respectively. The heat transfer coefficient values for particle sizes 30nm, 50nm, and 80nm were 5500 W/m2K, 4500 W/m2K, and 3500 W/m2K, respectively. The study also found that the heat transfer coefficient increased with increased heat pipe angle for all particle sizes, with the highest heat transfer coefficient obtained at a 90° heat pipe angle.
Cumulative Residual Entropy of the Residual Lifetime of a Mixed System at the System Level
Authors: Kayid Mohamed , Alshehri Mashael A.
Published: June 2023

Recently, there has been growing interest in alternative measures of uncertainty, including
cumulative residual entropy. In this paper, we consider a mixed system consisting of n components,
assuming that all components are operational at time t. We use the system signature to calculate
the cumulative residual entropy of the mixed system’s remaining lifetime. This measure is a useful
criterion for assessing the predictability of a system’s lifetime. We study several results related to the
cumulative residual entropy of mixed systems, including expressions, limits, and order properties.
These results shed light on the behavior of the measure and provide insights into the predictability
of mixed systems. In addition, we propose a criterion for selecting a preferred system based on
the relative residual cumulative entropy. This criterion is closely related to the parallel system and
provides a practical way to choose the best system configuration. Overall, the present study of
cumulative residual entropy and the proposed selection criterion provide valuable insights into the
predictability of mixed systems and can be applied in various fields.
Assessing Last Decimal Digits in Retracted Research Articles: Accounting for Missing Zeroes
Authors: Schumm Walter Richard
Published: June 2023

The cumulative nature of knowledge in science in general and for social science in particular
depends on research being conducted with integrity, with fraudulent research being one of the most
harmful of questionable research practices. It has been observed that, in fabricated research, there is
often a deficit of zeroes in the last digits of regression results. In research, authored by Dr. Eric A.
Stewart, that has been retracted, there appears to have been a paucity of zeroes as last digits in his
regression results. Eight hypotheses were tested to re-examine the relative lack of zeroes and possible
increases in ones or nines as last digits. Some support was found for all hypotheses. It appears that in
Stewart’s retracted research, ones and nines were substituted for zeroes as last digits. Furthermore, the
increased proportions of ones and nines was found to be highly correlated with other anomalies in the
same retracted articles, possibly indicative of fabrication of the results in the retracted articles. Further
research in this area might use symbolic interaction theory or justification theory to guide our
developing knowledge about this type of questionable research practice.
Material Evaluation and Dynamic Powder Deposition Modeling of PEEK/CF Composite for Powder-bed Fusion Process
Authors: Li Jiang , Peng Fulun , Li Hongguang , Ru Zhibing , Fu Junjie , Zhu Wen
Published: June 2023

Polymeric composites such as Poly-ether-ether-ketone (PEEK)/carbon fiber (CF) have been widely utilized due to outstanding performances such as high specific strength and specific modulus. The PEEK/CF components via powder-bed fusion additive manufacturing usually show brittle fracture behaviors induced by their poor interfacial affinity and inner voids. These defects are strongly associated with powder packing quality upon deposition. The particle dynamic model has been widely employed to study the interactions of particle motions. Powder property, bulk material property, and interfacial features of composite powders are key factors in the particle dynamic model. In this work, an efficient and systematic material evaluation is developed for composite powders to investigate their deposition mechanism. The discrete element method is utilized to simulate the dynamic behaviors of PEEK/CF composite powders. The powder properties, bulk material properties, and interfacial features of powders are calibrated and justified by experimental measurement, numerical simulation, and design of experiments. The particle dynamic model can well explain the powder flow behaviors and interactions. It reveals that the addition of short CF particles can assist the flow of PEEK powders and improve the packing quality of the composite powders.
Efficacy and Safety of Biological Therapies and Jak Inhibitors in Older Patients with Inflammatory Bowel Disease
Authors: Fries Walter , Basile Giorgio , Bellone Federica , Costantino Giuseppe , Viola Anna
Published: June 2023

With the introduction of more and more monoclonal antibodies selectively targeting various mediators of the immune-system, together with Janus-Kinase (JAK)-inhibitors with variable affinities towards different JAK subtypes, the available therapeutic options for the treatment of inflammatory bowel diseases (IBD) have undergone an acceleration in the last five years. On the other hand, the prevalence of IBD patients over 65-years of age is steadily increasing and, with this, there is a large population of patients that presents more comorbidities, polypharmacy, and, more frequently, frailty compared to younger patients, exposing them to potentially major risks for adverse events deriving from newer therapies, e.g. infections, cardiovascular risks, and malignancies. Unfortunately, pivotal trials for the commercialization of new therapies rarely include older IBD patients and those with serious comorbidities are virtually excluded. In the present review, we focus on existing literature from pivotal trials and real-world studies, analyzing data on efficacy/effectiveness and safety of newer therapies in older IBD patients with special emphasis on comorbidities and frailty, two distinct but intercorrelated aspects of the older population since age by itself seems to be of minor importance.

Individuals and their leadership competencies have been the sole focus of project leadership research, rather than the project leadership's behaviour and functions in project and organizational settings. As a result, this study investigates the project leadership functions and behaviours required for various project and organizational situations in order to propose a project leadership model that will be effective in all project and organizational situations. The model that was developed and tested in this study theorized on the project leadership function that project leaders are expected to perform as a result of their positions. It also described how project leaders could tailor their leadership functions and behaviours to address issues related to positions, organizational situations, and project situations. Three hypotheses were developed and tested using structural equation modelling to validate the model. The model's perceptive power demonstrates adequate validity. The model's validity implies that there are appropriate project leadership functions for different leadership levels and circumstances. The model's validity also implies that each project leadership behaviour has its own value, as conditions and necessities dictate. The study assumes that a project leader can embrace project leadership by combining a few different project leadership functions and behaviours.

Published: June 2023

This study investigates the relationship between clean and dirty energy markets, specifically focusing on clean energy stock indexes and their potential as hedging assets and safe havens during periods of global economic uncertainty. The research analyzes five clean energy indexes and five dirty energy indexes from May 2018 to May 2023, considering events like the global pandemic and the Russian invasion of Ukraine. The main objective is to examine the causal relationship among different stock indexes pertaining to dirty and clean energy by using the Granger causality test (VAR Granger Causality/Block Exogeneity Wald Test) to determine whether clean energy indexes can predict future prices of dirty energy indexes. However, the findings reveal that clean and dirty energy indexes do not exhibit hedging characteristics or serve as safe havens during times of economic uncertainty, rejecting the research question. These results have important implications for investment strategies, as assets lacking safe haven characteristics may not preserve portfolio efficiency in uncertain times. The study's insights provide valuable guidance for investors, poli-cymakers, and participants in energy financial markets. It highlights the need to adapt investment approaches and seek alternative options to navigate uncertain economic conditions effectively.

(1) Background: Breast cancer is a frequent heterogeneous disorder diagnosed in woman and is a high cause of mortality of them in reason to rapid metastasis and disease recurrence. Ferroptosis can inhibit breast cancer cell growth, improve the sensitivity of chemotherapy and radiotherapy and inhibit distant metastases so potentially acts on tumor micro-environment; (2) Methods: Ferroptosis/Extracellular matrix remodeling literature text-mining results were integrated in breast cancer transcriptome cohort according their distant relapse free survival (DRFS) under adjuvant therapy (anthracyclin+taxanes) and also in MDA-MB-231 transcriptome functional experiments with ferroptosis activations (GSE173905); (3) Results: Ferroptosis/Extracellular matrix remodeling text-mining identified 910 associated genes in at list 10 articles. Univariate Cox analyses censored on breast cancer (GSE25066) selected 252 individual significant genes and 171 of them found with an adverse expression. Functional enrichment of these 171 adverse genes predicted basal breast cancer signatures. By text-mining some ferroptosis significant adverse selected genes shared citations in domain of ECM remodeling such as: TNF, IL6, SET, CDKN2A, EGFR, HMGB1, KRAS, MET, LCN2, HIF1A, TLR4. A molecular score based on expression the eleven genes was found predictive of worst prognosis breast cancer at univariate level: basal subtype, short DRFS, high grade values 3 and 4, estrogen and progesterone receptors negative and nodal stages 2 and 3. This eleven gene signature was validated as regulated by ferroptosis inductors (erastin and RSL3) in triple negative breast cancer cellular model MDA-MB-231.; (4) Conclusions: Crosstalk between ECM remodeling-Ferroptosis functionalities allowed to define a molecular score which have been characterized as an independent adverse parameter in prognosis of breast cancer patients. Gene signature of this molecular score have been validated to be regulated by erastin/RSL3 ferroptosis activators. This molecular score could be promising to evaluate ECM impact of ferroptosis target therapies in breast cancer.

The western Sulige gas field is a new and key reserve area for the rolling development of the Sulige gas field in China. However, due to the complex gas–water relationship and the difficulty in identifying gas and water formation, the scale and benefit deployment of the gas field are seriously restricted. In particular, almost all of the wells in the area produce water and no water measurement has been carried out for any single well, which leads to an unclear understanding of the dynamic characteristics of the production wells, thus affecting the productivity calculations of the gas wells and the overall regional productivity evaluation. Based on the testing data for a gas well, the impacts of the reservoir property parameters on the gas and water production were analyzed by combining the production performance and static geological characteristics. It was determined that the physical parameters K, Kh, and φSg had good positive correlations with gas production but not with water production; thus, effective prediction cannot be obtained for water production in gas well testing. After the analysis of the liquid loading law, the gas wells were classified into three types: continuous liquid carrying production, slight liquid loading, and liquid loading wells. In general, up to 96% of the gas wells were liquid loaded. According to the different production performances exhibited in the different stages of the gas wells, five types of methods for diagnosing water production wells were proposed (gas testing, pilot production, gas–liquid two-phase measurement testing, liquid level detection, and production performance analysis), as well as the diagnostic criteria and corresponding solutions. To obtain real-time water production data for each well and investigate the change of water-gas ratio (WGR) during the whole production process, a water production splitting method for gas wells based on three-dimensional geological modeling and numerical simulation combined with the constraints of the total water production of gas gathering stations was explored and established. The splitting results can be used to evaluate the water and gas productivity of gas wells and determine the best deliquification period. The gas well productivity when water production was considered was about 10% lower than that when water production was not considered. The best deliquification period was determined to be 125 days for wells with small water production, 20 days for wells with moderate water production, and 3 days for wells with serious water production. The results of this study could provide technical support for the scientific evaluation of gas well production indicators, reduction of development costs, and improvement of oil recovery.
Preferential Recruitment of Monocyte into the Brain is Orchestrated by VCAM-1 Expression

The restriction of normal blood flow is the cause of many diseases including stroke and coronary artery diseases. To study the consequences of vessel blockade, previous models mainly focused on major arteries and have been well studied. However, the sequela from interruption of capillary vessels by microemboli was less well characterized. In this study, we exploited polystyrene microspheres as a mimicry of microemboli and found that microspheres of this size can be trapped in capillary vessels of all organs without causing apparent acute morbidities of the host. Interestingly, we accidentally found significantly increased recruitment of monocyte to the brain vasculature expressing low levels of Ly6C expression, but not to other organs. Further study revealed the spleen is the major origin of the recruited monocyte. Most importantly, VCAM-1 which is constitutively expressed on mouse brain vasculature orchestrates the recruitment of monocyte. Blockade of VCAM-1 in mice can substantially reduce monocyte recruitment. Interestingly, monocytes get activated through TNF- signaling which likely happens in the spleen instead of the brain. Collectively, we found a unique monocyte recruitment strategy in the brain comparing to other orangs, in response to capillary blockade induced by polystyrene microspheres.

The aim of this study was to compare the effectiveness of propofol-based sedation and midazo-lam sedation in same-day bidirectional endoscopy (BDE) in children. The charts of children (≤15 years old) who had undergone same-day BDE were retrospectively reviewed. Demographic data, indications, sedatives and their dosages, clinical outcomes, endoscopic findings, adverse events, and patient time requirements were compared in cases with propofol-based and midazolam se-dation. A total of 91 children [51 boys, mean age 13 years (range 9-15)] were enrolled. Propofol alone or in combination with midazolam and/or pentazocine was given in 51 (propofol-based sedation group) while midazolam alone or in combination with pentazocine was given in 40 (midazolam sedation group). The mean doses of propofol, midazolam and pentazocine were 96 mg (range 40–145 mg), 4.1 mg (range 3–5 mg) and 7.5 mg in the propofol group while the mean doses of midazolam and pentazocine were 6.2 mg (range 4–10 mg) and 15 mg in the midazolam group, respectively. The total procedure times and endoscopic findings between the two groups were similar, but the median patient time requirement in the propofol group was significantly shorter than that of the midazolam group (7.3 h vs. 8.4 h, P<0.001). No adverse events occurred in either group. Propofol-based sedation shortened patient time requirements in same-day BDE compared with midazolam sedation in children.
