Linum lewisii Adventitious and Hairy-Roots Cultures as Lignan Plant Factories

Plants synthesize specific secondary metabolites for survival, reproduction, environmental resilience, and defense. Among them, lignans are a class of polyphenols with several bioactive properties: chemopreventive, anti-inflammatory, antiviral, and antioxidant. These compounds are often extracted from field-grown plants with very low yields. To overcome these constraints, in vitro tissue cultures provide a tool to optimize large-scale production. Moreover, the use of elicitation to increase secondary metabolite production is gaining importance. The aim of this work was to develop adventitious (ARL) and hairy roots (HRL) from Linum lewisi, a species able to synthesize arylnaphthalene lignans such as justicidin B. The ARL and HRL were obtained for the first time and characterized for their phenol content, antioxidant activity, and the production of justicidin B after treatments with several elicitors and precursor feeding. Through NMR spectroscopy, other four lignans were highlighted and identified in the roots extracts. A pilot-scale bioreactor was adopted to assess the suitability of the developed root cultures for future large-scale production. The ARL and HRL cultures showed a justicidin B production higher than other Linum species cultures described up to now (75.8 mg/L and 82.2 g/L), and the production more than doubled after elicitation with MeJA.
Parenting Stress, Maternal Self-Efficacy and Confidence in Caretaking in a Sample of Mothers with Newborns (0–1 Month)

A mother’s responses to her newborn and her confidence in the child’s caretaking depend on her attachment security, general parental stress, and perceived self-efficacy. However, few studies have analyzed maternal confidence in caretaking and how it is influenced by some mothers’ characteristics. We aimed to examine the association between maternal adult attachment and confidence in a child’s caretaking and to understand whether this relationship was mediated by parenting stress and maternal self-efficacy. The sample consisted of 96 mothers with a mean age of 33 years with newborn children aged between 3 and 30 days. The instruments used were the Experiences in Close Relationships-Revised (ECR-R), the Mother and Baby Scale (MABS), the Parenting Stress Index Short Form (PSI-SF), and the Maternal Self-Efficacy Questionnaire (MEQ). The results showed a positive association between attachment avoidance and lack of confidence in caretaking, and this association was mediated by parenting stress. Conversely, attachment anxiety appeared not to influence confidence in caretaking, and maternal self-efficacy did not appear to mediate the relationship between attachment and confidence in the caretaking of infants. Our results could guide new research in studying confidence in caretaking and enable healthcare professionals to recognize at-risk situations early from the first month after childbirth.
Altmetric Attention Score and Its Relationships to the Characteristics of the Publications in the Journal of the American Chemical Society

ABSTRACT This article contributes to the discussion on the relationship between views, citations, number of references, number of authors, number of countries and the Altmetric Attention Score (AAS). The aim is to identify the metric most likely to complement traditional citations in scholarly publishing in chemistry. We used the publications in a top multi-disciplinary chemistry journal, the Journal of the American Chemical Society, for a three-year period for this study. We identified whether materials that are highly viewed correlates with higher number of citations and higher Altmetric Attention Scores; high AAS correlates with higher number of views and higher number of citations; higher number of citations correlates with higher number of views and higher AAS; (multi-authored works correlate with higher AAS, higher number of views and/or higher number of citations; and authors from more than one country correlate with higher number of views, higher citations and higher AAS.
League 3 of Indonesia Bali Zone: Shots and patterns of scoring a goal

An indicator of a success football team in a match is to score more goals than its opponents. Continuous and stable victories can be achieved by applying sports science and technology, one of them in this case is analyzing team performance. The purpose of this study is to describe the pattern of shots taken and goals scored during League 3 of Indonesia Bali Zone in 2021. The research method chosen for this study is descriptive quantitative research. A total of 38 matches are observed to see the number of shots and goals scoring patterns based on time intervals (15 minutes), type of play, number of passes before shot and goal scoring, player action before shooting and goal scoring, playing zone and player position in play. The result of this study indicates that 52.9% of shots occurred in the first half and 51.8% of goals are scored in the second half. Shots (78%) and goals (77%) occurred through the open play process. 61.2% of shots and 64.7% of goal scoring come from the lowest number of passes (0-4 passes). In the central ultra-offensive zone, there are 43.7% shots and 71.2% goal scoring. Based on the playing position, the midfielder recorded the number of shots 34.5% and the striker got 39.6% in scoring goals. The findings of this study can provide information for coaches in seeing the scoring pattern of all teams playing in the Indonesia League 3 Bali Zone. Therefore, it has implications for the way the coach prepares a tactical training program that focuses on how to goal scoring. The limitation of this study is that it has not identified the part of the goal area that produces score. It is important further to examine the part of the goal area where the ball is often conceded or scored by the opponent.

CYANanobot: Miniaturized Boat-Assisted Data Acquisition for Automated Cyanide Monitoring in Wastewater Using Optical Nano-Sensors

Cyanide contamination in water and wastewater is ubiquitous, particularly in gold mining industries, where cyanide is commonly used to extract gold. It is constantly being monitored by collecting samples which are analyzed in the laboratory using traditional cyanide analysis, which requires complicated instrumentation, skilled analysts, and expensive equipment. Using the gold nanoparticle (AuNP)-decorated paper-based sensor employing Whatman Filter Paper (WFP) as a substrate, an automated process for cyanide monitoring with the aid of an assembled and improvised remotely controlled miniature boat was developed. The technology is equipped with a filtration system with automated water sample collection and preparation with an automatic paper sensor dispenser. Images of the collected wastewater samples are taken at different time intervals and are analyzed on their respective color spaces based on 8 mathematical models, each predicting the cyanide level of the water sample. The predictions are compared to the actual Ion-Selective Electrode (ISE) measurement, and Root Mean Square Error (RMSE) values were calculated. The predictions at 165s using the Hue, Saturation, Value (HSV) color space exhibited the highest R2 of 0.85 and the lowest RMSE of 3.80 parts per million (ppm) with an average error of 3.40ppm. The predictions are sent to a database using Global System for Mobile Communications (GSM). The results suggest that the CYANanobot technology facilitates fast analysis time, circumvents the frequent instrument calibration, reduces operating costs, minimizes exposure to toxic cyanide-containing samples, and reduces person-to-person interaction.
The Associations between Daytime Physical Activity, While-in-Bed Smartphone Use, Sleep Delay, and Sleep Quality: A 24-h Investigation among Chinese College Students

Bedtime smartphone use is an emerging issue that threatens the sleep health of children and young adults. Physical activity can have numerous health benefits, including reducing problematic or addictive behavior. However, the role of daily physical activity in reducing bedtime smartphone use is understudied. Hence, we conducted a one-day cross-sectional on the weekend (21–22 May 2021) to investigate the associations between daytime physical activity, bedtime smartphone use, and sleep quality. A total of 828 college students were recruited in two colleges. Their daytime physical activity indices were captured, including self-reported physical activity duration, intensity, volume, and smartphone-monitored walking steps. The participants reported whether they used smartphone while lying in bed (before sleep) and whether they delayed sleep due to smartphone use. Their while-in-bed screen time (duration) and subsequent sleep quality were also measured with self-report and a numeric rating scale, respectively. The results suggested that daytime physical activity duration was associated with lower chances of while-in-bed smartphone use (OR = 0.907, p = 0.019) and smartphone-related sleep delay (OR = 0.932, p = 0.014). However, no significant association was found between physical activity indices and while-in-bed screen time or sleep quality. These findings may contribute to understanding the reciprocal relationship between physical activity and smartphone use and highlighting the potential of controlling problematic bedtime smartphone use through daily physical activity. Future research is warranted to examine the associations with extra objective measures.
Robust Zero-Sum Deep Reinforcement Learning

We present a method for evaluating the sensitivity of deep reinforcement learning (RL) policies. We also formulate a zero-sum dynamic game for designing robust deep reinforcement learning policies. Our approach mitigates the brittleness of policies when agents are trained in a simulated environment and are later exposed to the real world where it is hazardous to employ RL policies. The first problem we address is illustrating and demonstrating to verify our assumptions that deep RL policies are sensitive to disturbances, unmodeled dynamics or outright noise. In the second phase, we train two agents simultaneously in a zero-sum dynamic game; the goal is to drive the system dynamics to a saddle region. Using a variant of the guided policy search (GPS) algorithm, we evaluate, test and verify our assumptions. Our agent learns to adopt robust policies that require less samples for learning the dynamics.
Formulation and evaluation of the vascular endothelial growth factor loaded polycaprolactone nanoparticles

In an attempt to increase molecular stability and provide controlled release, vascular endothelial growth factor (VEGF) was encapsulated into polycaprolactone (PCL) nanoparticles. Both VEGF-free and VEGF-loaded PCL nanoparticles were formulated by w/o/w double emulsion of the dichloromethane-water system in the presence of polyvinyl alcohol (PVA) and rat serum albumin. To achieve the optimal formulation concerning particle size and monodispersity, studies were carried out with different formulation parameters, including PVA concentration, homogenization time and rate. Scanning electron microscopy and dynamic light scattering analysis showed respectively that particles had a spherical shape with a smooth surface and particle size varying between 58.68-751.9 nm. All of the formulations were negatively charged according to zeta potential analysis. In vitro release study was performed in pH 7.4 phosphate-buffered saline at 37°C and released VEGF amount was measured by enzyme-linked immunosorbent assay (ELISA) method. At the end of the 35th day, 10% of total encapsulated VEGF was released with a sustained-release profile, which fitted the Korsmeyer-Peppas kinetic model. The bioactivation of the nanoparticles was evaluated using XTT and ELISA methods. As a result, the released VEGF was biologically active and also VEGF loaded PCL nanoparticles enhanced proliferation of the human umbilical vein endothelial cells in cell culture.
Analysis and Design of an Ultrawideband Dual-Polarized Antenna for IBFD Applications

This communication investigates design requirements for a class of dual-polarized in-band full-duplex (IBFD) antennas utilizing a symmetry of structures and a differential-feeding scheme. The analysis reveals that, to achieve zero coupling between two ports, the out-of-phase power divider (PD) does not need to have perfect isolation and perfect matching at the two output ports. A more relaxed set of requirements for the PD is derived for the first time. Based on this, an ultra-wideband cross-shaped Vivaldi antenna is designed for IBFD applications with very high isolation. The measured 10 dB return loss bandwidth is 1.26–8.0 GHz (145.5%), while the measured port-to-port isolation is >42 dB at 1.26–4.7 GHz (115.4%) and >34 dB within the whole operational bandwidth.

Risk Area Alert Through Heterogeneous Mobile Networks: A New Approach to Fight COVID-19 and Beyond

COVID-19 has now been sweeping the whole world, and fundamentally affecting our daily life. An effective mechanism to further fight against COVID-19 and prevent the spread of this pandemic is to alert people when they are in the vicinity of areas with a high infection risk, yielding them to adjust their routes and consequently, leave these areas. Inspired by the fact that mobile communication networks are capable of precise positioning, data processing and information broadcasting, as well as are available for almost every person, in this article, we propose a mobile network assisted Risk arEa ALerting scheme, named REAL, which exploits heterogeneous mobile networks to alert users who are in/near to the areas with high risks of COVID-19 infection. Specifically, in REAL scheme, all base stations (BSs) periodically estimate their serving users' locations, which are then analyzed by macro BSs (MBSs) to identify risk areas. Next, each MBS transmits the information about risk areas to small BSs (SBSs), which in their turn adjust the beamforming direction to cover these areas and send alerts to users located therein. Simulation results validate the effectiveness of the proposed REAL scheme. In addition, some key challenges associated with implementing REAL are discussed at the end.
XNetMon: Uma Arquitetura com Segurança para Redes Virtuais

O isolamento entre máquinas virtuais é uma propriedade essencial para a segurança dos ambientes virtualizados, em especial, na aplicação de redes virtuais. Um compartilhamento dos recursos provido com isolamento impede que roteadores virtuais com um comportamento malicioso utilizem todos os recursos da máquina física, prejudicando o desempenho das outras redes virtuais. Esse trabalho propõe uma nova arquitetura para o Xen, capaz de prover o isolamento das redes virtualizadas. É proposto um mecanismo de segurança que monitora o uso dos recursos compartilhados e pune os roteadores virtuais com comportamentos maliciosos, garantindo assim a operação isolada das redes virtuais. Para garantir também a segurança no controle do encaminhamento dos dados, é proposto um protocolo para comunicação entre o domínio de gerenciamento e os roteadores virtuais que impede que roteadores virtuais maliciosos modifiquem as tabelas de encaminhamento de outros roteadores virtuais. Foi desenvolvido um protótipo e os testes mostram que a arquitetura proposta garante a disponibilidade do serviço de controle das redes virtuais, além de promover o compartilhamento dos recursos com mais precisão que outros mecanismos da literatura, propiciando o isolamento das redes virtuais.
Superacid Treatment on Transition Metal Dichalcogenides

Superacids are strong acids with an acidity higher than pure sulfuric acid. Recently, superacid treatment of monolayer transition metal dichalcogenide (TMDC) flakes, such as MoS2 and WS2, has shown a dramatic enhancement of optical properties, such as photoluminescence (PL) intensity. The superacid molecule is bis(trifluoromethane)sulfonimide (TFSI). In this review paper, we summarize and discuss the recent works and the current understanding of the TFSI treatment, and finally, we describe the outlook of the treatment on monolayer TMDCs.
Evaluating the impact of early childhood education on child development in Lao PDR

ABSTRACT Early childhood education (ECE) is important to provide the necessary support for children’s healthy development during the preschool period. We evaluated whether ECE positively impacted early childhood development in Lao PDR. We pooled two rounds of nationally representative cross-sectional household surveys — Lao Social Indicator Surveys 2011/2012 and 2017. The study sample included 9316 children 3–4 years old. Multivariate logistic regression and propensity score-matching analysis were performed to estimate the impact of preschool attendance on children’s development status. The results showed that preschool attendance positively impacted children’s literacy-numeracy, learning ability, physical growth, and social-emotional development. We confirmed that home stimulation by caregivers also positively impacted children’s literacy-numeracy and learning abilities. Since there are large socioeconomic and geographical disparities among Laotian children attending preschool, further efforts should be made to promote equitable and inclusive access to ECE in Lao PDR.
Study on the Improved Unscented Kalman Filter Ultra-Wideband Indoor Location Algorithm based on Two-Way Time-of-Flight

Traditional indoor location technologies based on wireless sensor network have difficulty in satisfying the requirements of positioning accuracy and real-time tracking in the non-line-of-sight (NLOS) environment due to considerable errors. In this study, an indoor location and tracking algorithm for the ultra-wideband (UWB) system was proposed to solve accurate location and tracking problems of the moving target in the complicated indoor environments. First, this algorithm measured the distance between tag and anchor accurately by the two-way time-of-flight (TW-TOF) method, and then calculated the position coordinates of the tag by the CHAN algorithm after the range measurement. Second, the coordinates of tag position were used as the observation value of unscented Kalman filter (UKF) with the state updating equation of UKF modified. Finally, the real-time position states and speed of the tag could be acquired. The proposed algorithm was compared with the extended Kalman filter (EKF) through a simulation experiment. Results demonstrate that the improve UKF algorithm can realize accurate location and dynamic tracking of the moving target in the indoor NLOS environment. The location accuracy of the proposed algorithm is 33.5% higher than that of the EKF algorithm. The study can provide certain references for accurate location and tracking of the moving target in the complicated indoor environments.
Influence of Trichomes on the Incidence of Two Spotted Spider Mite Tetranychus urticae on Brinjal

The present study evaluates the effect of host plant resistance by antixenosis (trichomes) in 40 brinjal entries to the two spotted spider mite Tetranychus urticae Koch, an important pest of brinjal. The maximum trichome density was observed (719.15/ 0.5cm2 leaf area) with the variety Namakkal local and minimum (276.82/ 0.5cm2 leaf area) was with Tiruppur local. Stellate type of trichomes were observed on all the entries, with maximum length on the upper surface of the leaves being 200.18 μm on Namakkal local, and on lower surface of leaves (269.36 μm) on Chinthapalli local-2. Manapparai local measured 247.40 μm long on midrib and 206.84 μm on veins. The correlation coefficients between the trichome density, length and T. urticae incidence revealed a significant negative correlation. Arka Nidhi was found to be resistant (2.07/cm2 leaf area) with low trichome density (427.50 μm).
Duplication and Segregation of Centrosomes during Cell Division

During its division the cell must ensure the equal distribution of its genetic material in the two newly created cells, but it must also distribute organelles such as the Golgi apparatus, the mitochondria and the centrosome. DNA, the carrier of heredity, located in the nucleus of the cell, has made it possible to define the main principles that regulate the progression of the cell cycle. The cell cycle, which includes interphase and mitosis, is essentially a nuclear cycle, or a DNA cycle, since the interphase stages names (G1, S, G2) phases are based on processes that occur exclusively with DNA. However, centrosome duplication and segregation are two equally important events for the two new cells that must inherit a single centrosome. The centrosome, long considered the center of the cell, is made up of two small cylinders, the centrioles, made up of microtubules modified to acquire a very high stability. It is the main nucleation center of microtubules in the cell. Apart from a few exceptions, each cell in G1 phase has only one centrosome, consisting in of two centrioles and pericentriolar materials (PCM), which must be duplicated before the cell divides so that the two new cells formed inherit a single centrosome. The centriole is also the origin of the primary cilia, motile cilia and flagella of some cells.
Second-order algebraic specification of static semantics

Higher-order algebraic speciication is a synthesis of rst-order algebraic speciication and higher-order functional programming which is both logically appealing as well as considerably more expressive than its two predecessors. To illustrate this, we describe the static semantics of a simple block-structured programming language using second-order equations in addition to rst-order ones. The speciication has a highly non-deterministic character and does not use a type environment. Furthermore, it supports error recovery and early detection of errors in incomplete programs.
Identity in Family Firms: Toward an Integrative Understanding

To take stock of the literature on identity in family firms (IFF), we examine 122 journal articles published between 2006 and 2020. We then develop a thematic map to help scholars understand the structure of IFF studies and the direction that IFF research is taking. Providing a consistent vocabulary and categorization, the thematic map serves to strengthen the IFF conceptualization and locates potential ambiguities and fragmentation. Thereafter, we analyze the antecedents, outcomes, and contingencies of the different themes identified. Drawing on this foundation, we identify gaps and suggest new directions and stimuli for future research.
