Strawberry algorithm and its newly evolved variant for pattern nulling in an antenna array

In this article attempt has been made for the first time to apply the reported strawberry optimization technique to antenna array synthesis problem. The algorithm is further modified by reinforcing it with adaptive values for the two key parameters known as runner length and root length embedded in the mathematical expression governing the movement of the mother plant from one position to another in the search space to locate the optimum solution. The case studies cited here refer to linear and circular array configurations. The design constraints are limited to minimizing the side lobe level and restricting the first null beam width, which play significant roles in antenna array performances. The important features which greatly influence in achieving the said objectives are either placement of antenna elements or amplitudes of excitations of these elements or both. And the recently reported nature inspired metaheuristic optimization algorithms have addressed to these antenna problems quite effectively and the application of the strawberry algorithm for the first time and the unraveling of a new algorithm known as reduced step size strawberry algorithm (rss-SBA) a variant of the existing SBA have shown quite exciting results thus opening avenues for these techniques to be the potential contenders in the race of authenticating their positions in the domain of nonlinear function optimization.
Understanding the ideological construction of the Gulf crisis in Arab media discourse: A critical discourse analytic study of the headlines of Al Arabiya English and Al Jazeera English

This article investigates the ideologisation of Arab media discourse and takes as a case in point the ideological construction of the Gulf crisis in the headlines of Al Arabiya English and Al Jazeera English. A corpus of 515 headlines produced between May and June 2017 is examined using an interdisciplinary critical discourse analytic framework. Analysis is conducted at two levels: a textual level concerned with the analysis of the semantic and syntactic aspects of headlines and a socio-cognitive level informed by insights from Van Dijk’s ideological square concept and his mental model theory and Laclau and Mouffe’s discourse theory. Findings indicate that both platforms are ideologically biased toward the political perspectives of their host states, although in a lesser degree in Al Jazeera English, and also reveal the various discursive strategies used to construct subjective mental models and reference frames to guide readers understanding of the crisis.
Nachweis der Vitalität von Ektomykorrhizen FDA‐Vitalfluorochromierung

Vor 100 Jahren wurde von A. B. Frank [2] der Begriff ,,Mykorrhiza" gepragt, was ,,Pilzwurzel" bedeutet. In diesem Wort spiegelt sich Franks Erkenntnis wieder, dai3 die Mykorrhiza ein symbiontisches System ist, welches aus Baumwurzel und Pilz besteht und sich fur beide Partner forderlich auswirkt. Mehr als 30 Jahre friiher hatte schon T. Hartig [5] das Vorhandensein von Pilzhyphen zwischen Rin-
Implementation of a separate fluid‐neutral energy equation in SOLPS‐ITER and its impact on the validity range of advanced fluid‐neutral models

In plasma edge transport codes for nuclear fusion devices, fluid‐neutral models offer an interesting alternative to the currently used kinetic Monte Carlo simulations, especially for cases of high ion‐neutral collisionality. In this paper, we elaborate a separate neutral energy equation in the state‐of‐the‐art SOLPS‐ITER code suite, which previously assumed perfect ion‐neutral temperature equilibration. Furthermore, we study the coupled plasma‐neutral solutions for a range of divertor operating regimes, proving the validity of these fluid‐neutral models for high‐recycling and detached regimes.
Research on short-term traffic flow prediction model based on RNN-LSTM

With the rapid development of economy and the increasing number of cars, it is the first task to effectively predict the traffic flow of road traffic to alleviate road congestion and reduce traffic accidents. Aiming at the uncertainty and nonlinearity of traffic flow data, the traffic flow prediction model based on long-term and short-term memory is designed and compared with the traditional BP model and RNN model. The simulation results show that the LSTM model has a higher prediction accuracy and better prediction effect on traffic flow.
Control Policies for a Large Region of Attraction for Dynamically Balancing Legged Robots: A Sampling-Based Approach

SUMMARY The popular approach of assuming a control policy and then finding the largest region of attraction (ROA) (e.g., sum-of-squares optimization) may lead to conservative estimates of the ROA, especially for highly nonlinear systems. We present a sampling-based approach that starts by assuming an ROA and then finds the necessary control policy by performing trajectory optimization on sampled initial conditions. Our method works with black-box models, produces a relatively large ROA, and ensures exponential convergence of the initial conditions to the periodic motion. We demonstrate the approach on a model of hopping and include extensive verification and robustness checks.
Benchmarking Engineering, Procurement and Construction (EPC) Power Plant Projects by Means of Series Two-Stage DEA

A lot of companies in the power sector use Engineering, Procurement, and Construction (EPC) contracts for complex infrastructure projects such as power plants. This paper presents a series two-stage data envelopment analysis (DEA) approach for the ex ante benchmarking of EPC power plant projects. The current study aims to improve over single-stage DEA and evaluate the efficiency of a group of twelve domestic (located in Greece) and international natural gas-fired power plant projects of different technologies (combined cycle power plant (CCPP) projects with single and multi-shaft configuration, and open cycle power plant (OCPP) projects) by employing a series two-stage DEA model. In the first stage, performance of the EPC mode is evaluated, whereas in the second stage the plant annual operational efficiency is assessed. In the light of the results, there is a lower level of performance in the EPC mode than in operating efficiency. The OCPP projects have the best operating efficiency, whereas they are ranked in-between the CCPP projects with single and multi-shaft configuration in EPC mode performance.
Inflation and Euro Membership

This article aims to investigate the relation between Euro membership and inflation. We construct two models that explain inflation using nonmonetary variables. To estimate these models, we collect yearly panel data for the 28 members of the European Union from 1998 to 2016. Due to the problem of endogeneity associated with some variables, we use the panel GMM following Arellano and Bond (1991) to perform all estimations. Results for the estimations of coefficients do not indicate a relation between membership in the Eurozone and inflation rates, neither for the short nor long term. Thus, the results can be considered contra-evidence for statements that the Euro increases short term inflation of its new members or that it reduces long term inflation rates permanently.
Acetobacter strains contain DNA modified at GAATTC and GANTC

Total DNAs from nine strains of Acetobacter xylinum, two strains of Acetobacter aceti, and one Acetobacter pasteurianus strain were examined for the extent of digestion by various restriction endonucleases. The majority of the endonucleases cleaved the total DNAs with a frequency expected from the number of sites present in DNA sequences deposited in the GenBank data base. However, the restriction enzyme digestions identified two different genomic DNA modifications in Acetobacter. One sequence-specific modification protected total DNAs from seven of the A. xylinum strains against cleavage by EcoRI (GAATTC). Digestion of total DNAs from A. xylinum ATCC 10245 (DNA not cut by EcoRI) and the closely related A. xylinum NRCC 17005 (DNA cut by EcoRI) with Tsp509I (AATT) revealed differences in restriction frequencies that indicated methylation of the first or second adenine within GAATTC. Another sequence-specific modification rendered total DNAs from all the 12 strains recalcitrant to digestion by HinfI. The la.
Exploring the Adoption of the International Information Security Management System Standard ISO/IEC 27001: A Web Mining-Based Analysis

In the light of digitalization and recent EU policy initiatives, information is an important asset that organizations of all sizes and from all sectors should secure. However, in order to provide common requirements for the implementation of an information security management system, the internationally well-accepted ISO/IEC 27001 standard has not shown the expected growth rate since its publication more than a decade ago. In this article, we apply web mining to explore the adoption of ISO/IEC 27001 through a series of 2664 out of more than 900 000 German firms from the Mannheim Enterprise Panel dataset that refers to this standard on their websites. As a result, we present a ‘‘landscape’’ of ISO/IEC 27001 in Germany, which shows that firms not only seek certifications themselves but often refer on their websites to partners who are certified instead. Consequently, we estimate a probit model and find that larger and more innovative firms are more likely to be certified to ISO/IEC 27001 and that almost half of all certified firms belong to the information and communications technology (ICT) service sector. Based on our findings, we derive implications for policy makers and management and critically assess the suitability of web mining to explore the adoption of management system standards.
The shell as a recording device: growth record and shell ultrastructure of Lampsilis radiata radiata (Pelecypoda: Unionidae)

Growth records retained in the shell of Lampsilis radiata radiata and shell ultrastructure were examined in a population from Lake Champlain, Vermont, U.S.A. Maximum size was 75 mm as measured from the umbo to the farthest margin. Ages were obtained by counting annual bands, and growth plots were constructed. By knowing the amount grown by individuals of the same age in the same year, the years 1975 and 1977 were identified as poor for growth of younger individuals. Light micrographs of shell thin sections showed macroscopic annual lines, and microscopic and ultrastructural lines. Ultrastructural lines were visible within macroscopic lines. Scanning electron micrographs of etched sections clarified the light micrographs and allowed recognition of two damage-response structures embedded within the nacreous layer in the umbonal region: adventitious conchiolin and prismatic crystals. Theories of growth line formation are presented. Shell growth appears to follow an alternating cycle of protein deposition as .
Method — A nonviral gene transfer method for transfecting multipotent adult progenitor cells (MAPC)

Multipotent adult progenitor cells (MAPC) are stem cells isolated primarily from adult bone marrow that have the ability to differentiate in vitro into cells with phenotypic and functional characteristics of cells from the three germ layers, namely endoderm, mesoderm and neuroectoderm. In addition, MAPCs proliferate for extended periods of time without obvious senescence. Hence, MAPCs may be ideal cells for therapy of genetic disorders, provided that the main impediment to gene therapy, namely efficient gene transfer and persistent gene expression, can be overcome. Most commercially available lipid-based methods that very highly efficiently transfect cell lines and primary cells, fail to transfect MAPC. However, 10–15% transfection of MAPC can be achieved using Superfect. However, this approach requires high density culture of MAPCs which subsequently differentiate. Between 12 and 15% transfection is achieved in MAPCs using electroporation, but this is highly toxic to MAPCs. Here, using transient expression of an enhanced green fluorescent protein (EGFP) gene, we report that nucleofection results in a transfection efficiency of over 25% with mouse MAPC without perturbing the conditions suitable for MAPC growth and maintenance, and with significantly less toxicity than electroporation. Similar results were seen for rat and human MAPC. Efficient transfection of MAPC by nucleofection offers an appealing non-viral mode of gene delivery and can be used to overexpress genes of interest in these cells. In addition, it should easily accomodate emerging site-specific integration technology, thereby culminating eventually in MAPC-mediated long-term gene therapy for genetic disorders.
Modelling and Simulation of Facility Planning Problem Based on Improved SLP Method

Facility planning plays a critical role in various fields. An excellent facility layout can minimize the losses caused by the connection between facility units in production operations. In this paper, we improved the traditional Systematic Layout Planning (SLP) method, combine it with the multi-objective decision optimization model. The Improved SLP (ISLP) method is described in detail in this paper, including its principles, process of building model, and calculation methods. To make the ISLP more suitable for research and practical problems, we established a mathematical model for it. This optimization model was also applied to the existing facility layout problem to realistically validate the effectiveness of the ISLP and the model. Results on the established model were found first, then the Flexsim simulation software was used to simulate the layout of the facility before and after the improvement. Finally, the results of the experiment were analysed and compared.
Selection of brown spot‐resistant rice plants from Helminthosporium oryzae toxin‐resistant calluses

Summary Helminthosporium oryzae toxin induced electrolyte leakage from rice callus tissues and caused their browning and death. A virulent isolate of the pathogen invaded and colonised callus tissues rapidly, while a less virulent and a nonpathogenic isolate colonised calluses only weakly if at all. Addition of the toxin to calluses permitted colonisation of calluses by the nonpathogenic isolate. Four toxin-resistant calluses were selected and plants regenerated from two of these resistant calluses showed resistance to the pathogen. This resistance was heritable and stability of resistance was observed in the R1, R2 and R3 generations.
USDA-ARS Research on Practices Compatible with Organic Agriculture for Management of Plant-Parasitic Nematodes on Vegetable Crops

Abstract The market for organically grown fruits and vegetables has been increasing in recent years, and research is vital for obtaining optimal quality and yields in organic production systems. Scientists at the United States Department of Agriculture-Agricultural Research Service (USDA-ARS) are investigating methods for managing plant-parasitic nematodes on these crops, and studies that involve practices appropriate for organic vegetable production are reviewed in this paper. The projects summarized here focus primarily on suppression of root knot nematode species, including Meloidogyne arenaria (Neal) Chitwood, M. hapla Chitwood, M. incognita (Kofoid and White) Chitwood and M. javanica (Treub) Chitwood. Projects from Florida include investigations of plant growth-promoting rhizobacteria (PGPR) and chitin amendments for management of nematodes on pepper (Capsicum annuum L.), muskmelon (Cucumis melo L.), and tomato (Solanum lycopersicum L.). In South Carolina, research programs focus on the identification, characterization, and development of host plant resistance to root-knot nematodes in bell and hot peppers (Capsicum L.), southernpea [cowpea; Vigna unguiculata (L.) Walp. ], and watermelon [Citrullus lanatus (Thunb.) Matsumura and Nakai]. Collaborative research in Georgia and South Carolina concentrates on the utilization of root-knot nematode-resistant bell pepper for managing root-knot nematodes in double-cropped squash (Cucurbita pepo L. cv. Cougar) and cucumber (Cucumis sativus L.). Research conducted in Maryland involves the use of rye (Secale cereale L.) and velvetbean (Mucuna Adans.) cover crops as nematotoxin-producing soil amendments, and application of beneficial microbes and their metabolites for suppression of root-knot nematodes on bell pepper, cucumber, tomato, and muskmelon. This research contributes to development or improvement of nematode management strategies that do not rely on the use of synthetic nematicides.
Multilayer SOH Equalization Scheme for MMC Battery Energy Storage System

It is preferable for the retired batteries to balance their states-of-health (SOH) in the battery energy storage system (BESS) since it can prolong the system lifetime and reduce the maintenance burden. So far, the corresponding balancing techniques mainly focus on either the SOH balancing among packs or the SOH balancing of cells inside a pack. This article further proposes the multilayer SOH equalization scheme to equalize all cells’ SOHs of large-scale BESS by comprehensively combining the pack SOH balancing strategy and the commercial cell equalization techniques. It is noted that the balancing schemes for pack and cell cannot be simply superimposed since packs and cells have totally different connection modes and are equipped with different types of balancing circuits. In specific, the modular multilevel converter (MMC) is assumed to coordinate the pack and cell SOH equalization schemes, where the charging/discharging power per submodule is properly adjusted according to the extent of cell SOH deviation and the extent of pack SOH deviation together. MATLAB simulation and experimental results of a 10-kWh MMC-BESS prototype verified the performance of the proposed method.
Male Survivors’ Perceptions of Post-Traumatic Stress Disorder (PTSD) Management Strategies in the South African Mining Sector

Deep-shaft mining is regarded as a high-risk occupation with an increasing number of traumatic accidents. Though there are strategies for the management of post-traumatic stress disorder (PTSD), little has been done to document the male survivors’ perceptions of PTSD management strategies in the South African mining sector. An exploratory, descriptive and contextual study was conducted within the South African mining sector to explore and describe the survivors’ perceptions of PTSD management strategies. The population comprised all men who were suffering from PTSD as a result of accidents in the mines. A purposive sample of 29 men was selected to participate in the study and data saturation was achieved. Unstructured individual interviews and field notes were used as methods of data collection. One question was asked during the interviews: “What do think helped you recover from PTSD? ” Communication skills were employed to facilitate the participation of the men during the interviews. Data were collected using a voice recorder and were then transcribed verbatim and analysed using Tesch’s descriptive method of data analysis. Measures for ensuring trustworthiness were applied to verify the findings. Three themes emerged during data analysis: (1) perceived emphasis on physical versus psychological treatments, (2) perceived coping strategies used to deal with the trauma, and lastly, (3) the perceived effect of social support networks during trauma. Based on the perceptions of the participants, it became evident that PTSD management did not meet expectations. An integrated approach is recommended for the future treatment of psychological and physical trauma among survivors of traumatic events in the mining sector.

Spams classification and their diffusibility prediction on Twitter through sentiment and topic models

ABSTRACT Alike web spam has been a major issue to almost every aspect of the current World Wide Web, social spam has led to a serious threat to the utilities of online social media, particularly in information diffusion. To combat this challenge, the significance and impact of social media and its content should be analyzed critically. To address this issue, Twitter is used as a case study, where we have modeled the contents of information through topic models and coupled it with the user-oriented features to predict spam diffusion with a good accuracy. Latent Dirichlet Allocation (LDA), a widely used topic modeling technique is applied to capture the latent topics from the tweets’ documents. The major contribution of this work is twofold. Firstly, analyzing the variation of sentiment and topics in spam/non-spam information, and secondly, constructing a feature set that classifies tweets more accurately into spam and non-spam category as compared to the existing approaches. The extensive simulation reveals the variation in sentiments and topics shared by the spam and non-spam tweets.
Converging on a nativist core? Comparing issues on the Facebook pages of the Pegida movement and the Alternative for Germany

Computational methods offer a new perspective on the evolving agendas of right-wing movements and parties online. This article showcases computational approaches to text analysis (specifically so-called topic models) to diachronically investigate nativist right-wing issues in social media by comparing comments posted on the Facebook page of the Pegida movement to those of the Alternative for Germany. After describing topic modelling as an increasingly popular method and drawing on the literature on right-wing nativism online, we investigate a set of shared issues relevant to the mobilization of commentators, including opposition to Islam, migration, the government and the media. We furthermore show contrastively how issue prevalence differs between the two groups, and how issue shares change over time, in some instances converging on a shared nativist core. We close with a series of suggestions on the utility of computation content analysis for the study of rapidly evolving political agendas.
