OBJECTIVES
The current study examined longitudinal linkages between child sleep duration and children’s socioemotional, learning engagement, executive functioning, and academic outcomes across the full kindergarten (K) year.

METHODS
A measurement-burst design was employed to examine 3 different measures of child sleep duration in 7-day bursts at pre-K (July–August), early K (late September), mid-K (late November), and late K (mid-to-late April), using wrist actigraphy. These measures included mean amounts of child sleep per 24-hour period across the full week, proportion of 24-hour periods per week that children slept 10 or more hours, and proportion of nighttime sleep periods per week that children slept 10 or more hours. Children’s outcomes at early, mid-, and late K were provided by their K teachers blind to children’s sleep histories, and by assessments administered by project staff.

RESULTS
Among the 3 sleep measures examined, regularity of nighttime sleep in which children slept 10 or more hours per night, especially at pre-K, consistently predicted more favorable K outcomes in both socioemotional, learning engagement, and academic domains. Results suggested that establishing healthy nighttime sleep habits before K start was especially promotive of better K adjustment across the full K year. These findings were controlled for income-to-poverty threshold ratios, child health status, and number of missed school days.

CONCLUSIONS
Efforts to promote a favorable transition to first-time schooling should pay particular attention to sleep hygiene and regularity of 10-plus hours of nightly child sleep established before the start of K.

Increased concentration of cell-free DNA (cfDNA) in the circulating blood of humans and animals is a sign of inflammatory conditions and a distinctive characteristic of various pathophysiological processes in the body. The aim of the present study was to investigate the possible role of tumor necrosis factor (TNFα) in changes of cfDNA contents in peripheral blood as a response to experimentally induced systemic inflammation.We used 40 female hybrid mice (C57Bl/6xDBA/2) F1 at the age of 6-8 weeks. The concentration of cfDNA and its individual fractions was determined using a PicoGreen fluorescent dye. The dynamics of inflammatory process was evaluated after 4, 8, 11 and 24 hours following LPS injection. A significant increase in the blood plasma cfDNA levels was shown under the action of E. coli lipopolysaccharide (LPS), along with simultaneous decreased levels of cfDNA, associated with cell surface. The ratio of cell surface-bound cfDNA to the total cfDNA contents was reduced in dose-dependent manner as early as 4 hours after LPS injection to the animals, thus allowing us to consider this ratio a characteristic sign of netosis of neutrophilic granulocytes during the development of acute inflammation. The described effects are significantly suppressed with co-injection of recombinant TNFα neutralizing protein along with LPS, whereas increased intake of neutrophils in the tissues is determined by some other factors which are not directly related to the production of this cytokine.Based on the obtained data, we proposed a following hypothesis: induction of netosis by inflammatory stimuli causes an increase in the concentration of cfDNA in blood plasma not only due to de novo emerging extracellular DNA by neutrophil netosis, but also by the release of distinct cfDNA fraction that was previously firmly bound to cell membranes in multiple body tissues under the action of proteases released during netosis.

AbstractObjective. Despite the potential role of valproic acid (VPA) in weight gain, the effects of VPA therapy on lipid profiles remain unclear. This study aimed to review the influence of VPA therapy on serum lipid profiles in children with epilepsy.Methods. This meta‐analysis was conducted on data from PubMed, Web of Science, Cochrane Library, and Embase databases. Case‐controlled studies, which assessed the effects of VPA therapy on lipid profiles, were included. All outcomes were recorded as continuous variables, and the effect size was measured.Results. VPA therapy was associated with a significant reduction in total cholesterol (mean difference [MD]=‐6.34, 95% confidence interval [CI]: ‐12.30, ‐0.37, p=0.04) and low‐density lipoprotein cholesterol levels (MD = ‐7.75, 95% CI: ‐13.48, ‐2.0, p=0.008). No significant effects were observed regarding the levels of high‐density lipoprotein cholesterol and triglycerides.Significance. In conclusion, this meta‐analysis indicates that VPA therapy causes a decrease in the levels of total cholesterol and low‐density lipoprotein cholesterol.

As a result of measures related to the liquidation of inefficient universities and low-quality education, the university network of Russia in 2013-2019 has significantly changed its configuration. In particular, the total number of universities decreased by 42%, including parent universities by 23%, branches by 56%. At the same time, the number of students decreased by 33% over the same period, the reform occurred during a period of demographic decline in the youth age cohorts. However, the consequences of the reform to optimize the network of universities could have a different impact on the structure of urban and regional higher education systems in different parts of the country. Most of the federal and departmental statistics describing the situation in the field of higher education, and, accordingly, the results of research, are presented at the national or regional levels. However, almost all universities are located in cities, and this key level from the point of view of spatial localization of educational institutions falls out of the pool of educational analytics and research. Large cities everywhere attract young people with a wide range of factors. One of them is the possibility of choosing a university and an educational program. Other factors are related to the quality of the environment and services, the breadth and diversity of the labor market, which positively distinguish large cities from less populated places. The available data do not allow us to divide the migration attractiveness of the city for young people into those related to the presence of a university and the quality of educational services provided by it and those related to other possible factors of attractiveness. However, we can analyze whether there presentation of universities in cities of different sizes is correlated with their migration attractiveness, expressed in net migration indicators of 15-19-year olds. The conducted research has shown that the cities with a population of over 250 thousand people are the most attractive for migration and at the same time the least subjected to the reorganization of the university network. The concentration of universities in the largest cities of the country contributes to the strengthening of centripetal migration of young people. Small towns have experienced the main consequences of the implementation of state policy measures aimed at improving the quality of higher education. For many applicants from small and medium-sized cities, having one university or branch was the only opportunity to get a higher education without leaving their hometown.
MCMTpy: A Python Package for Source Parameters Inversion Based on Cut-and-Paste Algorithm and Markov Chain Monte Carlo
Authors: Yin Fu , Wang Baoshan 
Published: July 2022

Abstract
Accurate earthquake source parameters (e.g., magnitude, source location, and focal mechanism) are of key importance in seismic source studies and seismic hazard assessments. The routine workflow of source parameters estimation consists of two steps: source location inversion and focal mechanism inversion. Separate inversion of source parameters is subject to the cumulative uncertainties of both two steps inversion processes. Markov Chain Monte Carlo (MCMC), as global optimization, has been adopted in many nonlinear inversion problems to reduce cumulative errors and provide uncertainty assessment, but the application of MCMC is strongly subject to prior information. In this study, we present a new Python package MCMTpy. MCMTpy exploits the Cut-And-Paste (CAP) algorithm and Bayesian inference, using Markov Chain to implement the source location inversion and focal mechanism inversion in one inversion workflow. The new approach can effectively reduce the prior model dependence, and is closely integrated into the current seismological programming ecosystem. To demonstrate the effectiveness of the new package, we applied the MCMTpy to the 2021 Ms 6.4 Yangbi earthquake, Yunnan, China, and 2008 Mw 5.2 Mt. Carmel Earthquake, Illinois. A comparison between our results and other catalogs (e.g., Global Centroid Moment Tensor and U.S. Geological Survey W-phase) solutions illustrates that both double-couple and moment tensor solutions can be reliably recovered. The robustness and limitations of our approach are demonstrated by an experiment with 30 different initial models and an experiment with the grid-search method.
Scoping the Eco-sensitive Mythology in the Works of Amruta Patil and Appupen
Authors: Saini Himanshi 
Published: July 2022

Purpose of the study: The study aims to delve into the potential of the graphic novel in the Indian context, for which I have used the works of Amruta Patil and Appupen. The paper investigates the concerns of environment, mythology, and feminine experience and its presentation on a graphic-literary landscape.
Methodology: The methodology used in the paper is that of direct observation. The researcher has used the contributions of Pramod K. Nayar and Emma Varughese further to push the boundaries of the graphic novel in India.
Main Findings: The paper’s main findings have been to bring to light the complex mesh of interdisciplinary strategies required to scope the medium of the graphic novel. The paper narrows down on the success of the graphic novel as a medium to address the issues of the environment in a much more nuanced manner.
Applications of the study: This research can be used to widen the scope of Literary Eco-criticism. It includes the medium of the graphic novel and seeks to examine its operative strategies when raising attention to the issues that pertain to the environment.
Novelty/Originality of the study: The terrain of the Indian Graphic Novel is still new and developing. While some studies have been done in this medium around the themes of the concerns of the cosmopolitan Indian, little has been done to look into the mythological roots and environmental concerns that this genre also illuminates. This essay is a significant step in that direction.

Published: July 2022

Con más de veinte lenguas pertenecientes a seis familias lingüísticas, el Gran Chaco despierta el interés de los lingüistas dedicados a la tipología y comparación de lenguas. No obstante, mientras que las similitudes fonológicas y gramaticales han estado en el foco de la mayoría de esos estudios, la investigación de los patrones semánticos ha tenido hasta ahora un papel menor. Este trabajo retoma el problema de la semejanza y posible difusión de rasgos entre las lenguas del Chaco por medio de la identificación y el análisis de patrones léxico-semánticos compartidos en el vocabulario etnobiológico de dieciséis lenguas de la región. Nuestra investigación ha sido realizada con asistencia de técnicas específicas de anotación y procesamiento de datos mediante el programa EDICTOR que permite, a diferencia de los métodos clásicos, trabajar con un amplio corpus de datos disponibles de manera digital. Los resultados preliminares del análisis dan cuenta de que en el dominio estudiado los lexemas exhiben paralelismos semánticos basados en una misma motivación léxica. Dicha motivación se expresa en el plano formal mediante recursos como la derivación y la composición y, en menor medida, la polisemia, mientras que en el plano conceptual prevalecen la metáfora y la metonimia

Published: July 2022

Background: The maternal mortality rate in Indonesia is still high and still far from the established target of SDG's, which is 307 maternal deaths per 100,000 live births. Adequate antenatal cares are needed to reduce maternal mortality. This study aims to determine the quality of antenatal care (ANC) services at public health centers by the framework of systems (Input, process, and output). Methods: This study is a descriptive study with qualitative designs. Data collection was conducted in 12 health centers and the sample size is 12 midwives in the health centers. Midwives were interviewed about input, process and output components related to integrated antenatal program (ANC Terpadu 10T). In addition, it was observed also the availability of facilities, infrastructure and K1 and K4 rate related to ANC in health centers. Results: Human resources in the implementation of the integrated antenatal program by midwives at the Surabaya's Health Center still do not meet the minimum health human resources standards. Public Health Centers observed have facilities and infrastructure to support integrated antenatal care.

Published: July 2022

Tubal ligation is a long-term contraceptive and relatively non-adverse, but the problem is that fecundity return surgery for couples who want to change plans to add more children cannot be guaranteed and the cost is very expensive. The research aims to analyze the factors that influence tubectomy contraception for acceptors aged less than 40 years in Pangkalpinang City in 2016. The research type was explanatory with a cross-sectional design. The sample was tubectomy contraceptive acceptors of 95 people. Data analysis was performed using a Chi-square test to determine the relationship between variables. The results showed there was no relationship between maternal education (p=0.512), husband's education (p=0.802), maternal job (p=0.522), parity (p=0.533), knowledge (p=0.484), and support from their husband (p=0.622) with tubectomy less than 40 years of age. The reasons for tubectomy that are most often cited are related to health factors and family factors/number of children. Almost all respondents (98%) stated that they were satisfied after having a tubectomy seen from several factors including the reasons underlying the desire for tubectomy, the amount of support, the attitude, and role of the husband, support from the family, community, and role models, and easy access to costs and places to get tubectomy health services.
Comparative hydraulic and sedimentologic study of ripple formation using experimental turbidity currents and saline currents
Authors: Koller Débora Karine , Manica Rafael , Fedele Juan Jose 
Published: July 2022

ABSTRACTSaline currents (SCs) have commonly been used to model muddy turbidity currents (TCs) in a laboratory. However, little is known about the limitations of this proxying, in particular when concerning processes and products related to their sedimentologic and stratigraphic imprints. The present study is aimed at investigating experimental hydraulic and sedimentological conditions and processes involved in the generation and development of bedforms by both SCs and TCs, when similar input conditions are applied (discharge, slope, densimetric Froude number). In all performed runs reported herein, only ripples were observed to form, and were identified and classified using known criteria such as their dimensions, near-bed shear stresses (), shear velocities (), and grain Reynolds values (Re*). Turbidity currents were observed to deposit sediments carried by the flow predominantly in the upstream section of the flume, increasing bed slope and thus increasing , , and near-bed concentrations (cb). This resulted in longer-wavelength bedforms compared to those generated by SCs under similar input conditions in those sections of the flume. On the other hand, along the downstream sections of the flume, bed slopes were observed to remain similar for all experiments, and both types of currents showed similar vertical distribution of velocities, concentrations, and stable stratification. Measured bedform wavelengths and heights were slightly higher when generated by SCs, due to the coarser bed material observed in SCs (which influenced the increase in near-bed turbulent intensities). Moreover, TCs presented a slight decrease in turbulence intensities due to their observed high near-bed suspended-sediment concentration. Spatial and temporal changes in several hydraulic parameters in both SCs and TCs highlight the role of sediment suspension in modifying turbulent processes and vertical stratification of these flows, depending on their concentrations. Both hydraulic and sedimentologic observations of this study support in principle the assumption that SCs can be used experimentally as a surrogate for diluted TCs to reproduce bedforms classified as ripples, as long as both type of currents reach similar hydraulic and sediment-transport conditions, in particular for depth-averaged concentration Cvol &lt; 1% and near-bed concentration cb &lt; 2%.
Modeling Two-Phase Flow Caused by Hydrate Dissociation in a Reservoir on the Concept of Global Pressure

Published: July 2022

Summary
The classic Darcy’s two-phase flow equation has a variety of mathematically equivalent formats, such as pressure/saturation (PS), two-phase pressure (PP), and global pressure/saturation (GP). Based on the concept of global pressure, we derive a new formulation for two-phase flow caused by hydrate dissociation in porous media, coupled with the mass and energy conservation equations, thereby offering a novel theoretical frame for gas hydrate extraction simulation. The new model provides in-depth insights into complex flow fields: The dissociation of hydrates under thermal stimulation may lead to two flow fields of gas and water with different directions in the reservoir. The simulation results are in good agreement with the recorded data set of Masuda’s and Chong’s experiments, which verifies the correctness and applicability of the new model.
Based on numerical simulations of the same hydrate dissociation experiments, the efficiency of the GP method was compared with the PP method published in our previous work. The results show that the GP method has more than two times the timestep size of the PP method for unsteady flow and 1.5 times for steady flow. Furthermore, the relative residual of the GP method is even two orders of magnitude lower than that of the PP method for two-phase flows with complex variations of pressure gradient and fluid flux. Therefore, the GP method is significantly more efficient than the PP method for simulating gas hydrate development.
The proposed GP method improves the computational efficiency of hydrate extraction simulation at the laboratory scale and understanding the mechanisms of two-phase flow in reservoirs caused by hydrate dissociation. It may have potential advantages for field-scale simulation of hydrate development, which requires further studies to demonstrate.

Abstract
Given the importance of metals in the contamination of aquatic ecosystems, studies are needed to assess the effects of these contaminants on aquatic organisms through different contamination pathways. Chromium (Cr) is a metal widely used in various industrial processes, considered a priority pollutant in several countries. In the present study, ecotoxicological tests were carried out with the microalga Chlorella vulgaris, evaluating the effects of Cr on cell density, pigment concentration, and biochemical composition. Additionally, the effects of chromium exposure on cladocerans (Ceriodaphnia dubia and Ceriodaphnia silvestrii) were investigated through three contamination routes: contaminated medium, contaminated food (C. vulgaris), and the combination of both situations (contaminated medium and food). The toxicity tests with cladocerans evaluated the metal effects on survival, number of newborn produced by female, and feeding activity. The results obtained demonstrated that 48 µg L-1 total dissolved Cr reduced cell density and increased protein, carbohydrate, and lipid content in C. vulgaris. The increase in the biochemical composition of microalgae upon exposure to Cr may have contributed to the non-observation of chronic toxic effects on daphnids in the treatment with contaminated food. A decrease of 31% and 26% in the number of C. silvestrii offspring was observed for the treatment with contaminated medium (35 µg L-1 total dissolved Cr) and associated treatment (35 µg L-1 total dissolved Cr and 3 × 10-14 g Cr cells-1), respectively. The importance of the Cr poisoning pathways and the difference in cladoceran species’ sensitivity to the metal were addressed.
Intrusion Detection System Using Classification Algorithms with Feature Selection Mechanism over Real-time Data Traffic

Published: July 2022

Abstract
The key objective of intrusion detection systems (IDS) is to protect the particular host or network by investigating and predicting the network traffic as an attack or normal. These IDS uses many methods of machine learning (ML) to learn from past-experience attack signatures and identify the new ones. Even though these methods are effective, but they have to suffer from large computational costs due to considering all the traffic features, together. Moreover, emerging technologies like the Internet of Things (IoT), Big data, etc. are getting advanced day by day, as a result, network traffics is also increasing rapidly. Therefore, the issue of computational cost needs to be addressed properly. Thus, in this research, firstly, the ML methods have been used with feature selection technique (FST) to reduce the number of features by picking out only the important ones from NSL-KDD and CICIDS2017 datasets that helped to build IDSs with lower cost but with the higher performance which would be appropriate for vast scale network. The experimental result proved that the proposed model i.e. Decision tree (DT) with Recursive feature elimination (RFE) performs better than other classifiers with RFE in terms of accuracy, specificity, precision, sensitivity, F1-score, and G-means on both datasets.
