Published: June 2020

AbstractIntroduction: The present study examines the relationships between processing speed (PS), mental health disorders, and learning disorders. Prior work has tended to explore relationships between PS deficits and specific diagnoses in isolation of one another. Here, we simultaneously investigated PS associations with five diagnoses (i.e., anxiety, autism, ADHD, depressive, specific learning) in a large-scale, transdiagnostic, community self-referred sample. Method. 843 children, ages 8–16 were included from the Healthy Brain Network (HBN) Biobank. Principal component analysis (PCA) was employed to create a composite measure of four PS tasks, referred to as PC1. Intraclass correlation coefficient (ICC) between the four PS measures, as well as PC1, were calculated to assess reliability. Results. ICCs were moderate between WISC-V tasks (0.663), and relatively modest between NIH Toolbox Pattern Comparison and other PS scales (0.14–0.27). Regression analyses revealed specific significant relationships between PS and reading and math disabilities, ADHD-inattentive presentation (ADHD-I), and ADHD-combined presentation (ADHD-C). After accounting for inattention, the present study did not find a significant relationship with Autism Spectrum Disorder. Discussion. Our examination of PS in a large, transdiagnostic sample suggested more specific associations with ADHD and learning disorders than the literature currently suggests. Implications for understanding how PS interacts with a highly heterogeneous childhood sample are discussed.

Published: June 2020

AbstractLightweight sheet alloys with superior mechanical performance such as high strength, ductility and formability at room temperature (RT) are desirable for high volume automotive applications. However, ductility or formability of metallic alloys at RT are generally inversely related to strength, thereby making it difficult to optimize all three simultaneously. Here we design a new magnesium sheet alloy-ZAXME11100 (Mg-1.0Zn-1.0Al-0.5Ca-0.4Mn-0.2Ce, wt. pct.) via CALPHAD (CALculation of PHAse Diagram) modeling and experimental validation. This new sheet alloy offers an excellent RT formability with a high Index Erichsen (I.E.) value of 7.8 mm in a solution-treated condition (T4), due to its weak and split basal texture and fine grain structure. The new ZAXME 11100 alloy also shows a rapid age-hardening response during post-forming artificial aging treatment at 210 °C for 1 hour (T6), resulting in a significant increase of yield strength from 159 MPa (T4) to 270 MPa (T6). The excellent combination of T4 ductility (31%), T4 formability (7.8 mm) and T6 yield strength (270 MPa) in this new magnesium alloy is comparable to that of common 6xxx series aluminum sheet alloys. Thus, this new magnesium sheet alloy is highly attractive for sheet applications in automotive and other industries.

AbstractAs an effective method, diesel particulate filter (DPF) technology has a great contribution in reducing soot emissions from diesel engines. To achieve passive regeneration of DPF at low temperatures, K-doped Ce0.5Mn0.5O2 catalysts were synthesized using sol–gel method. The effect of K-doped catalysts-Kz–Ce0.5Mn0.5O2-on the oxidation of soot had been studied by thermogravimetric analysis, and the corresponding catalytic properties were evaluated based on X-ray diffraction (XRD), hydrogen temperature programmed reduction (H2-TPR), O2 temperature programmed desorption (O2-TPD) Raman spectroscopy (Raman), Brunauer–Emmett–Teller (BET) and Fourier-Transform-Infrared (FTIR).The results showed that K doping facilitated the oxidation of diesel particulate matter, which was indicated by the entire mass loss curve shifting to lower temperatures. K0.2–Ce0.5Mn0.5O2 showed the best performance among the series of K-doped catalysts. Compared with the findings for Ce0.5Mn0.5O2, the ignition temperature of soot oxidation (Ti) had been lowered by 28 ℃, and the maximum peak combustion temperature (Tm) of the dry soot decreased by 61 °C. Furthermore, compared with the Ce0.5Mn0.5O2-catalyzed reaction, K doping led to a lower activation energy and significantly improved pre-exponential factor. The minimum reaction activation energy of 27.46 kJ/mol was exhibited by K0.2–Ce0.5Mn0.5O2.

AbstractSpodoptera frugiperda is one of the main pests of maize and cotton in Brazil and has increased its occurrence on soybean. Field-evolved resistance of this species to Cry1 Bacillus thuringiensis (Bt) proteins expressed in maize has been characterized in Brazil, Argentina, Puerto Rico and southeastern U.S. Here, we conducted studies to evaluate the survival and development of S. frugiperda strains that are susceptible, selected for resistance to Bt-maize single (Cry1F) or pyramided (Cry1F/Cry1A.105/Cry2Ab2) events and F1 hybrids of the selected and susceptible strains (heterozygotes) on DAS-444Ø6-6 × DAS-81419-2 soybean with tolerance to 2,4-d, glyphosate and ammonium glufosinate herbicides (event DAS-444Ø6-6) and insect-resistant due to expression of Cry1Ac and Cry1F Bt proteins (event DAS-81419-2). Susceptible insects of S. frugiperda did not survive on Cry1Ac/Cry1F-soybean. However, homozygous-resistant and heterozygous insects were able to survive and emerge as fertile adults when fed on Cry1Ac/Cry1F-soybean, suggesting that the resistance is partially recessive. Life history studies revealed that homozygous-resistant insects had similar development, reproductive performance, net reproductive rate, intrinsic and finite rates of population increase on Cry1Ac/Cry1F-soybean and non-Bt soybean. In contrast, heterozygotes had their fertility life table parameters significantly reduced on Cry1Ac/Cry1F-soybean. Therefore, the selection of S. frugiperda for resistance to single and pyramided Bt maize can result in cross-crop resistance to DAS-444Ø6-6 × DAS-81419-2 soybean. The importance of these results to integrated pest management (IPM) and insect resistance management (IRM) programs is discussed.
Implementation of output impedance in single‐phase inverters with repetitive control and droop control
Authors: Astrada Juan , De Angelo Cristian 
Published: June 2020

A strategy for the implementation of the output impedance in single‐phase inverters connected in parallel with droop control for uninterruptible power supply applications is proposed in this study. The proposal allows the load current to be distributed in proportion to the power capacity of the inverters connected in parallel, by establishing the magnitude and phase of the output impedance at the fundamental frequency and its harmonics, when the voltage control is performed through odd harmonic repetitive controllers. This is accomplished through the design of an output impedance profile based on the transfer function of a second‐order high‐pass filter and a virtual impedance loop. The proposal achieves a correct operation of the droop control strategy and the proper sharing of the harmonics of the non‐linear load current between the inverters connected in parallel, obtaining reduced values of individual harmonic content and harmonic distortion in the output voltage with reduced processing requirements. The validity of the proposal is verified through a 2 kVA experimental prototype, considering the requirements of the international quality standards IEC62040‐3 and IEC61000‐2‐2, in terms of output voltage regulation, individual harmonic content, and harmonic distortion for inverters operating both in islanded‐mode and in parallel.
Improved harmonic injection pulse‐width modulation variable frequency triangular carrier scheme for multilevel inverters
Authors: Orfi Yeganeh Mohammad Sadegh , Sarvi Mohammad , Blaabjerg Frede , Davari Pooya 
Published: June 2020

This study proposes an optimised controllable pulse‐width modulation (PWM) scheme suitable for multilevel inverters. Seeing the need for improving the output voltage characteristics such as total harmonic distortion, low‐order harmonic and distortion factor, an improved harmonic injection PWM variable frequency triangular carrier modulation technique is employed for off‐line mode. For this purpose, the carrier signal frequencies at each level (carrier‐based), and also amplitudes and orders of the harmonic‐injected signal (reference‐based) are considered as controllable parameters. The proposed technique benefits are operating with considerably fewer numbers of the pulses per cycle, low switching losses, and improvement in the output voltage characteristics. However, selective harmonic elimination and optimal switching angles are the most common modulation techniques, but they employ only one angle as a control parameter at each level of the output waveform. Hence, the modulation scheme can consider more angles at each level as controllable parameters by applying multi‐objective particle swarm optimisation and non‐dominated sorting genetic algorithm II (NSGA‐II). Simulations are conducted in 5‐, 7‐ and 9‐level inverter. Finally, the effectiveness of the studies is validated by obtaining experimental results on a single‐phase 1 kW 7‐level inverter prototype.
Improving the methodology of sample preparation of sunflower seeds when determining the content of oleic acid by NMR
Authors: Agafonov Oleg , Prudnikov Sergey 
Published: June 2020

Developing modern instrumental express methods for monitoring quality parameters requires special attention to the comparability of measurement results with reference methods. This article includes the result of improving the method for determining oleic acid content in sunflower seed oil using pulsed NMR technique. In the conditions of industrial laboratories, different seed quality and temperature have the greatest influence on the accuracy of measuring oleic acid content. It is possible to reduce the influence of different quality by increasing the number of simultaneously analyzed samples. A method for preliminary SHF treatment of seeds was proposed that could significantly reduce the time of seed sample preparation with the temperature below 15°C. Due to the special characteristics of SHF treatment, seeds are heated under certain parameters to the temperature of 20-25°C without loss of moisture contained in the analyzed sample what is especially important for the comprehensive determination of quality parameters of sunflower seeds using pulsed NMR method.
To eliminate temperature influence, it was proposed to measure the temperature of each analyzed sample before the analysis. This allowed significant increasing the accuracy of measuring oleic acid content. These solutions were implemented in a sampling device that made a sample with a volume of 25 cm3 and at the same time measured its temperature.

Abstract
Fungi play an important role in our life. Several species of fungi act as biocontrol agents, antibiotic producers, and waste material decomposers. On the other hand, several harmful fungi cause problems by attacking plants, humans, and animals, while others can spoil our food. Fungi attacking plants result in various diseases in the roots, stems, leaves, flowers, and fruits, which could result in either mild reduction in the yield or complete loss of a crop. There are also some fungal species that reside inside the plant tissues without causing diseases (endophytes) and others that survive as saprophytes on plant leaves, stems, or roots without causing damage to plants. Considerable knowledge and reviews have been generated on the effects of plant pathogenic fungi on plants’ survival and yield.  Although some studies indicated the possible effects of plant fungi on humans and animals, there is a lack of a comprehensive review on this aspect. This review paper discusses the direct and indirect effects of plant pathogenic and saprophytic fungal species on humans and animals.
Generation of elliptically polarized soft x rays using high-order harmonic generation with orthogonal two-color laser fields
Authors: Milošević D B , Becker W 
Published: June 2020

Abstract
High-order harmonic generation by orthogonally polarized two-color (OTC) laser fields is analysed using strong-field approximation and quantum-orbit theory. Results for the field components frequency ratio of 2:1 and 3:1 are presented and compared. We have shown that, depending on the relative phase between the field components, the shape of the high-harmonic spectrum can be very different from that obtained by a monochromatic linearly polarized laser field. It is also shown that it is possible to generate elliptically polarized high-order harmonics with very high photon energies using OTC laser field with the frequency ratio of 3:1 and a long fundamental wavelength. An effective relative phase control of the harmonic emission is demonstrated. The obtained results are explained using the quantum-orbit theory.

Published: June 2020

Abstract
A vertex coloring c : V(G) → ℕ of a non-trivial connected graph G is called a sigma coloring if σ(u) ≠ σ(v) for any pair of adjacent vertices u and v. Here, σ(x) denotes the sum of the colors assigned to vertices adjacent to x. The sigma chromatic number of G, denoted by σ(G), is defined as the fewest number of colors needed to construct a sigma coloring of G. In this paper, we determine the sigma chromatic numbers of the Sierpiński gasket graphs and the Hanoi graphs. Moreover, we prove the uniqueness of the sigma coloring for Sierpiński gasket graphs.

Abstract
Recently information technology has developed rapidly like the development of computer hardware and software. By the existence of internet technology, the process of data transfer can be done by others from a separate place and outside the system environment. The ease of data access remotely (using the internet) does not mean that they are always positive or good, but they also make new problems for the information world. The biggest problems when using the internet are slow access speeds and security when transferring data. Communication via internet is very susceptible to data loss or changed that caused by system errors or actions from non responsible persons. According to Kadir (2011) errors in data transfer via internet are caused by two reasons, that are the existence of human error or improper user intervention and the existence of technical errors from its system. Many efforts have been made by internet users to solve the problem of data transfer, including encoding data that will be sent in order to no user can read the data except the person has the right to receive it. Just not encoding, there is also an authentication process or validation of the data received, this is done to ensure that the data received is correct or does not changed. In this paper, the author propose a modification of the caesar cipher where if the key used previously is a real number, then we change the key into the coloring of vertices on the graph. So the key that used in this method is a graph. The core of this research is that every character of the plaintext has affiliation with each vertex of the graph, so that if the vertex of the graph gets 4 colors for example, then the characters of the plaintext affiliated with that vertex are also added with 4. This process will be repeated until all characters in the plaintext are coded according to the color of vertex. If the number of the characters plaintext is greater than the number of vertices, then the repeat process will occur until all the characters from the plaintext have affiliation with the vertex on the key graph.

Abstract
Let F, G and H be graphs. Notation F → (G, H) means that there is any two-coloring, say red and blue, of all edges of F which contains red subgraph isomorphic to G or blue subgraph isomorphic to H. The graph F is Ramsey (G, H)-minimal graph if F → (G, H) but F − e ↛ (G, H) for any e ∈ E(F). The class of all Ramsey (G, H)-minimal graphs will be denoted by R(G, H). In this paper, we proved that there are only two graphs with six vertices that belong to Ramsey minimal graphs for certain pair of path and cycle (P

6) and we also determined some graphs with eight vertices in R(P

Abstract
The ability to manage knowledge is becoming increasingly important in today’s knowledge economy, especially for companies. In order to obtain the effectiveness of the process of sharing knowledge within the company, it is necessary to evaluate the implementation of the knowledge management system that is currently running. The purpose of knowledge management is to change the paradigm of existing knowledge in employees into knowledge that can explicitly become corporate or organizational knowledge, so that the company can be used to improve employee performance because there are sufficiently managed references or knowledge or experience or expertise that has been collected and disseminated by previous employee.The data obtained were then analyzed using the factor analysis method, and the results that five factors can affect employee performance through knowledge management systems implementation, these are the factors: human resources ability, effective information, knowledge management systems, Quality for Users, accurate information transfer, and adequate IT Infrastructure. Furthermore, from these five factors by using linear regression analysis a mathematical model can be built which can be simulated to illustrate the results of the evaluation.

Abstract
Banyuwangi is a district in East Java province in Indonesia which is known as the Rice Barn of East Java. Banyuwangi region is facing challenges such as population growth, increased consumption of rice, reduced agricultural land because there are several agricultural land used as non-agricultural land. Because of there are production it is not enough from objects with just one period, therefore the use of data panels is one solution because it considers the time period and objects needed to determine the factors that influence rice production. In this study the analysis to model panel data from rice production in Banyuwangi was Generalized Additive Mixed Model (GAMM) and Generalized Estimating Equation GEE. In general GAMM as a mixed model, contains random effects so that this model is very useful when inference about individual differences is a major interest. While GEE is a model used to provide the population averaged effect. GEE also has the feature of smoothing natural cubic spline and B-spline so that it can be called GEE (+ NS/BS) which aims to improve the goodness of fitting a model. In this study, we want to see the effect of the total rainfall, harvest area, and population density on rice production. we also develop GAMM in the form of web interface to make users easier to analyze data using GAMM through http://statslab-rshiny.fmipa.unej.ac.id/RProg/MSD/.

Published: June 2020

Abstract
Chaos Game is a form of game drawing a point on a field with certain rules that are repeated iteratively. In general, the new point in the game chaos is the midpoint of the starting point and reference point. The new point is the result of the dilatation with the center of the reference point with a half dilatation factor. The resulting points will form a pattern by paying attention to the nature of self-similarity. This paper will examine the modification of the game chaos rules in generating new points by varying the r compression ratio applied to triangles and rectangles. The compression ratio will be divided into four different intervals. The results of this study indicate that variations in the compression ratio for r = −1, 1orr → +®or 0 < r < 1or −1 < r < 0 do not produce a fractal object, while r > 1or r < −1 will produce a fractal object.

Abstract
This research discussed the modelling of an electromagnetic wave radiation exposure on a smartphone which helped by the Mat Lab program. The modelling that was used to solve the intensity radiation was an inversion modelling. Inversion modelling can be defined as a mathematical and statistical method that used to obtain information based on obervational data which is processed into formulation. The purpose of this research was to determine the strong forms of exposure that existed in smartphone with 3 G and 4 G network types. The difference of network types aimed to find out the different forms of the received exposure. The method that was used in this research was done by taking field data which was matched with the calculating data. In order to obtain the suitability of theoretical data and field data, an experimental process can be carried out so that the appropriate results will be obtained and illustrated in graphical form.
