A DOUBLE-SHRINK AUTOENCODER FOR NETWORK ANOMALY DETECTION

The rapid development of the Internet and the wide spread of its applications has affected many aspects of our life. However, this development also makes the cyberspace more vulnerable to various attacks. Thus, detecting and preventing these attacks are crucial for the next development of the Internet and its services. Recently, machine learning methods have been widely adopted in detecting network attacks. Among many machine learning methods, AutoEncoders (AEs) are known as the state-of-the-art techniques for network anomaly detection. Although, AEs have been successfully applied to detect many types of attacks, it is often unable to detect some difficult attacks that attempt to mimic the normal network traffic. In order to handle this issue, we propose a new model based on AutoEncoder called Double-Shrink AutoEncoder (DSAE). DSAE put more shrinkage on the normal data in the middle hidden layer. This helps to pull out some anomalies that are very similar to normal data. DSAE are evaluated on six well-known network attacks datasets. The experimental results show that our model performs competitively to the state-of-the-art model, and often out-performs this model on the attacks group that is difficult for the previous methods.

BUSINESS MODEL INNOVATION FOR CIRCULAR ECONOMY: INTEGRATING LITERATURE AND PRACTICE INTO A PROCESS MODEL

Abstract To implement circular economy, manufacturers will need to develop new business models. Available approaches are granular, generic, infrequently focusing on advice or implementation, and lacking practical demonstration. This article presents how a tool was proposed to cover these gaps. Based on design research methodology, twenty-two conceptual and practical requirements were identified and translated in functions for the development of the Circular Economy Business Model Configurator, a tool that supports manufacturers in strengthening proposals of business models for circular economy.
Effect of Sesbania sesban on cultivation of Agaricus bisporus, Basidiomycota, and properties of spent mushroom compost outcome

Abstract Because wheat straw has a high cost as a feed for livestock, this work aims to use straw of Egyptian pea (Sesbania sesban) in compost preparation as an alternative for the cultivation of Agaricus bisporus. Six composts were used within this study on two mushroom strains A. bisporus (C9 and F599 strains). The type of compost has a significant (p<0.05) effect on the size of button mushroom fruits. WHS1 compost exhibited the best diameter of pileus at 5.28 cm while WCS1 compost showed the lowest diameter reaching 4.68 cm. A. bisporus C9 had the longest stipe while A. bisporus F599 has the greatest cap diameter.A. bisporus F599 showed a larger ratio of the diameter of pileus to the length of stipe (DP/ LS ratio) (1.14) compared with C9 (1.07). C:N ratios of compost decreased significantly (p<0.05) after cultivation of mushrooms because of the high increase of nitrogen content in spent mushroom compost (SMC). Finally, the straw of S. sesban is suitable as a supplement for the cultivation of A. bisporus.
Local super antimagic total vertex coloring of some wheel related graphs

Let G be a simple and finite graph with vertex set V and edge set E. The local antimagic total labeling of G is a map from V ∪ E to the set of positive integers from 1 to |V| + |E| such that the weight of two adjacent vertices are distinct. The weight of a vertex v is calculated by the sum of the label of the vertex v and the labels of all edges incident to it. If the vertices of G is labelled by the smallest labels, that is, {1, 2,…, |V|}, then the such labeling is called local super antimagic total labeling. Thus, the local super antimagic total labeling induces a proper vertex coloring of G where the vertex v is colored by the weight of vertex v. The minimum number of colors taken over all colorings induced by super local antimagic total labeling of G, is called local super antimagic total chromatic number of graph G, and denoted by χlsat (G). In this paper, we consider the local super antimagic total chromatic number of some wheel related graphs such as fans, even gear graphs, and sun flower graphs.
Antigen-specific T-cell receptor signatures of cytomegalovirus infection

Cytomegalovirus (CMV) is a prevalent human pathogen. The virus cannot be eliminated from the body, but is kept in check by CMV-specific T cells. Patients with an insufficient T-cell response, such as transplant recipients, are at high risk of developing CMV disease. However, the CMV-specific T-cell repertoire is complex, and is not yet clear which T cells protect best against virus reactivation and disease. Here we present a highly resolved characterization of CMV-specific CD8+ T cells based on enrichment by specific peptide stimulation and mRNA sequencing of their T-cell receptor β chains (TCRβ). Our analysis included recently identified T-cell epitopes restricted through HLA-C, whose presentation is resistant to viral immunomodulation, and well-studied HLA-B-restricted epitopes. In 8 healthy virus carriers, we identified a total of 1052 CMV-specific TCRβ chains. HLA-C-restricted, CMV-specific TCRβ clonotypes the ex vivo T-cell response, and contributed the highest-frequency clonotype of the entire repertoire in 2 of 8 donors. We analyzed sharing and similarity of CMV-specific TCRβ sequences and identified 63 public or related sequences belonging to 17 public TCRβ families. In our cohort and in an independent cohort of 352 donors, the cumulative frequency of these public TCRβ family members was a highly discriminatory indicator of carrying both CMV infection and the relevant HLA type. Based on these findings, we propose CMV-specific TCRβ signatures as a biomarker for an antiviral T-cell response to identify patients in need of treatment and to guide future development of immunotherapy.
Two-step Calibration Method for Triaxial Magnetometers

In this paper, two important sources of the non-orthogonal errors of triaxial magnetometers were analysed. The non-orthogonal error mainly come from the transverse sensitivity of uniaxial sensor or non-orthogonality between the three axes of magnetic magnetometer. These two error sources were separated by mathematical analysis. Then a two-step calibration method of triaxial magnetometers was designed. It showed that the peak-to-peak value of the calculated result of the scalar of magnetic field could be reduced to 56nT from 350nT within the range of 50000nT.
Coal combustion: Nuclear resource or danger

Both the benefits and hazards of coal combustion are more far-reaching than are generally recognized. Technologies exist to remove, store, and generate energy from the radioactive isotopes released to the environment by coal combustion. When considering the nuclear consequences of coal combustion, policymakers should look at the data and recognize that the amount of uranium-235 alone dispersed by coal combustion is the equivalent of dozens of nuclear reactor fuel loadings. They should also recognize that the nuclear fuel potential of the fertile isotopes of thorium-232 and uranium-238, which can be converted in reactors to fissionable elements by breeding, yields a virtually unlimited source of nuclear energy that is frequently overlooked as a natural resource. In short, naturally occurring radioactive species released by coal combustion are accumulating in the environment along with minerals such as mercury, arsenic, silicon, calcium, chlorine, and lead, sodium, as well as metals such as aluminum, iron, lead, magnesium, titanium, boron, chromium, and others that are continually dispersed in millions of tons of coal combustion by-products. The potential benefits and threats of these released materials will someday be of such significance that they should not now be ignored.
Nitrogen-status sensing in Arabidopsis

Plant nitrogen use efficiency (NUE) is important in agriculture because it significantly influences yield and fertiliser requirements. Many factors influence NUE; these include nitrogen availability, internal nitrogen-status, nitrogen uptake and assimilation rates as well as carbon status. Previous attempts to improve NUE by targeting the main nitrogen uptake or assimilation machinery (e.g. over-expression of nitrate reductase or glutamine synthetase) have had mixed results. This is because these enzymes are strictly controlled by multiple feedback mechanisms relating to internal and external nitrogen-status. Arguably, a better approach to manipulating NUE would be to identify and supress these feedback signals either alone, or in conjunction with over-expression of the uptake and assimilation machinery. This could enhance exploitation of nitrogen resources leading to increased growth. Internal nitrogen-status signalling is poorly understood. However, it is known that amino acids, when exogenously supplied, inhibit the uptake of nitrate. The mechanism for this inhibition has not been identified, but it is likely the result of sensing of internal nitrogen status, the amino acids representing a signal of nitrogen sufficiency, in turn leading to reduced expression and activity of the nitrogen uptake and assimilation machinery. In this thesis I conducted a reverse-genetic screen based on the response of candidate amino acid transporter knock-out mutants to exogenous alanine. In wild-type Arabidopsis, exogenous alanine caused inhibition of vegetative growth, which is accompanied by a reduction in nitrate uptake and transcripts encoding nitrate transporters. In the reverse-genetic growth screen, I identified four mutants with vegetative growth that was insensitive to exogenous alanine. Further characterisation of these mutants revealed that nitrogen uptake was not inhibited and this was accompanied by a lack of repression of nitrate transporter transcripts. Based on this evidence, I concluded that these amino acid transporter mutants were perturbed in nitrogen-status signalling. However, the origin of this signalling perturbation remains unclear. I formulated two hypotheses to explain how four amino acid transporter mutants could have the same signalling phenotype. The first suggested that the four alanine-insensitive transporters could form a functional complex, which is part of the nitrogen-status signalling pathway. The second suggested that the loss-of-function of the amino acid transporter perturbs metabolite levels, in a common way in each mutant, producing a metabolic signature which is sensed downstream of the transporter by an unknown mechanism. The latter hypothesis was tested by extensive metabolite profiling and I could find no evidence in support of the hypothesis. Preliminary investigations were made of the functional-complex hypothesis but technical problems prevented significant progress.
Lecanora markjohnstonii (Lecanoraceae, lichenized Ascomycetes), a new sorediate crustose lichen from the southeastern United States

Abstract Lecanora markjohnstonii is described as new to science from the southeastern United States, with a primary center of distribution in the southern Appalachian Mountain region. This sterile, sorediate crust is saxicolous on both sandstone and granite and occurs commonly in mixed hardwood-conifer forests with rock outcrops. It is characterized by a gray-green, rimose-areolate thallus, erumpent, raised soralia, and the production of atranorin together with 2-0-methylperlatolic acid. Molecular phylogenetic analyses of newly generated rDNA assemblies from a broad sampling of lineages within the Lecanoromycetes and Arthoniomycetes inferred placement of the unknown crust in the Lecanoraceae, specifically within Lecanora. Analysis of the mtSSU gene region then inferred placement in the Lecanora subfusca group. Finally, a fully assembled and annotated mitochondrial genome was compared to other lichenized fungal mitogenomes, including the publicly available Lecanora strobilina mitogenome, and showed that the gene region atp9 was missing as in other members of the Lecanorales.
Elucidating small RNA pathways in Arabidopsis thaliana egg cells

Small RNA pathway components and small RNA profiles of flowering plant egg cells are largely unexplored, mainly because they are not easily accessible but deeply buried inside the ovary. We describe here the utilization of proliferating callus tissue that adopted transcriptome features of Arabidopsis egg cell as a tool to explore small RNA pathway components and small RNA profiles in egg cells. We furthermore complement our studies with mRNA-Seq data from isolated Arabidopsis egg cells and provide data validation by promoter-reporter studies and whole mount in situ hybridization. Sequencing of small RNA libraries demonstrate the predominance of TE-derived siRNAs in the egg cell-related callus. TE-features and expression profiles suggest post-transcriptional silencing of activated Gypsy-like LTR retrotransposons, whereas the majority of class II DNA transposons belonging to Copia, CACTA, hAT-like and Mutator superfamilies are subjected to transcriptional silencing. Small RNA-seq furthermore led to the identification of differentially expressed known and novel miRNAs whose expression in the egg cell was verified by small RNA whole mount in situ hybridization. Both the strong expression of miRNAs in the egg-cell-adjoining synergids and the secretion of miRNAs into the micropyle suggest hitherto undescribed roles for these accessory cells in intercellular communication with the egg cell and the arriving pollen tube. In conclusion, our datasets provide valuable and comprehensive resources to study small RNA pathways and small-RNA-mediated epigenetic reprogramming during egg cell differentiation and the onset of plant embryogenesis.
Detection and molecular characterization of the cucumber mosaic virus in chili pepper (Capsicum spp. L.) crops

The chili pepper (Capsicum spp. L.) is a vegetable of economic importance that has been affected worldwide by the cucumber mosaic virus (CMV), a pathogen that causes a devastating disease in this crop. The aim of this research was the detection and characterization of CMV in chili pepper crops in Valle del Cauca, Colombia. Leaves of three chili pepper varieties (tabasco, cayenne and habanero) with viral symptoms were collected in four municipalities of Valle del Cauca. Total RNA was purified and a fragment of capsid protein (CP) from CMV was amplified by RT‑PCR. Then, it was sequenced and bioinformatically analyzed, and from these sequences, specific primers were designed. From 71 chili pepper samples collected in Palmira, Yumbo, Vijes and Yotoco, 37 were positive for CMV (52.1%). The CMV chili pepper sequence analysis showed that they had their highest identity (98.5%) with a CMV isolated from bananas in Ecuador. Specific primers designed for CMV chili pepper showed greater sensitivity for detecting this virus (64.7% vs. 52.1%). The CMV chili pepper CP analysis indicated that it could be transmitted by the species Aphis gossypii. This r the first time, the molecular characterization of CMV in three chili pepper varieties.
Automatic detection of number-plate and traffic infractions of motorcyclists by Intelligent Transportation Systems

Public Transportation Strategic Systems are a digital transformation for the urban transportation service in the Colombian medium-size cities, from 200,000 to 600,000 inhabitants. The implementation of the urban public transportation services has not started in many cities; as a result, this cities in Colombia have an increase of illegal motorcycle taxis, which cause a high number of road accidents. The main method for controlling illegal motorcycle taxis is by giving the drivers transit fines. In order to give such transit fines, transit police have several control points in medium-size cities. In this article, we developed a mobile application to detect three types of transit infractions usually committed by motorcycle taxi drivers. The purpose of this application is to be a tool for the transit police agents to disincentivize the use of motorcycle taxis. The mobile application detects a possible transit infraction, saves the photo, motorcycle plate number, date, and time. Afterwards, the application generates a support for the transit infractions that will be issued by the transit police officer. We performed an experiment using this mobile application in the city of Valledupar, Colombia. The mobile application captured 40 possible transit infractions.
Nutritional supplementation required by native Cerrado species development, in nursery

The ecological restoration of Cerrado ecosystems involves challenges pertinent to the fertilization of the substrate for seedlings in nursery, which are often produced by a single type of substrate. However, habitat heterogeneity suggests that the species may have different nutritional requirements. The objective was to assess the effect of substrate fertilization and nutritional supplementation by leaf in developing seedlings of Kielmeyera coriacea Mart. & Zucc. Eugenia dysenterica (Mart.) and DC Handroanthus impetiginosus (Mart. ex DC.) Mattos. The experiment was implemented in a 3x3 factorial completely randomized design (three types of substrates x three levels of foliar fertilization), with ten replicates. The treatments were tested by analysis of variance. For K. coriacea and H. impetiginosus, it is recommended to use a substrate composed of Soil + Manure (2:1), for E. dysenterica , it is recommended to use the complete substrate. Foliar fertilization is not recommended for all species. Regarding the soil analysis, organic matter, phosphorus and calcium were determinants in the formation of fertility groups for each of the major components of the Principal Component Analysis.
Genomic Insights into the Adaptive Convergent Evolution

Adaptive convergent evolution, which refers to the same or similar phenotypes produced by species from independent lineages under similar selective pressures, has been widely examined for a long time. Accumulating studies on the adaptive convergent evolution have been reported from many different perspectives (cellular, anatomical, morphological, physiological, biochemical, and behavioral). Recent advances in the genomic technologies have demonstrated that adaptive convergence can arise from specific genetic mechanisms in different hierarchies, ranging from the same nucleotide or amino acid substitutions to the biological functions or pathways. Among these genetic mechanisms, the same amino acid changes in protein-coding genes play an important role in adaptive phenotypic convergence. Methods for detecting adaptive convergence at the protein sequence level have been constantly debated and developed. Here, we review recent progress on using genomic approaches to evaluate the genetic mechanisms of adaptive convergent evolution, summarize the research methods for identifying adaptive amino acid convergence, and discuss the future perspectives for researching adaptive convergent evolu-tion.
INFLUENCE OF INNOVATION, COMPLEXITY AND NEWNESS ON SUCCESS IN NEW PRODUCT DEVELOPMENT PROJECTS: A SURVEY IN NORWEGIAN MANUFACTURING INDUSTRY

Abstract There is little tolerance for deviation in time, budget and quality in the execution of product development projects. On the other hand, the project environment is gaining complexity. Changes on project scope are daily business. We set up an initial hypothesis, that unplanned changes -newness- has negative impact on projects. We developed and executed therefore a survey about factors belonging to innovation, complexity and newness to test their perceived impact on project success. Our data show a positive correlation between unsuccessful projects and newness, which is discussed in the paper.
Subsampled Data Based Alternative Regularized Estimators

Subsampling the data is used in this paper as a learning method about the influence of the data points for drawing inference on the parameters of a fitted logistic regression model. The alternative, alternative regularized, alternative regularized lasso, and alternative regularized ridge estimators are proposed for the parameter estimation of logistic regression models and are then compared with the maximum likelihood estimators. The proposed alternative regularized estimators are obtained by using a tuning parameter but the proposed alternative estimators are not regularized. The proposed alternative regularized lasso estimators are the averaged standard lasso estimators and the alternative regularized ridge estimators are also the averaged standard ridge estimators over subsets of groups where the number of subsets could be smaller than the number of parameters. The values of the tuning parameters are obtained to make the alternative regularized estimators very close to the maximum likelihood estimators and the process is explained with two real data as well as a simulated study. The alternative and alternative regularized estimators always have the closed form expressions in terms of observations that the maximum likelihood estimators do not have. When the maximum likelihood estimators do not have the closed form expressions, the alternative regularized estimators thus obtained provide the approximate closed form expressions for them.
DERIVATION OF STARTING SOLUTIONS BASED ON PRODUCT ARCHITECTURE FLEXIBILITY EVALUATION

Abstract Manufacturing companies nowadays face growing numbers of heterogeneous customer requirements. Due to that, internal and external complexity lead to an increase in the associated costs. Especially companies with a high Engineer-to-Order business are strongly affected. To reduce external and internal complexity, Starting Solutions are a suitable way to do that. Starting Solutions require on the one hand the evaluation of product flexibility, on the other hand the evaluation of customer requirements. These two requirements are compared to each other and Starting Solutions are thereby derived.
Firm Performance and Exports: Evidence from the Romanian Wine Industry

Abstract This paper examines the impact of exports and its main determinants on the financial performance of the Romanian wine industry. We draw on a dataset consisting of mixed firm-level (i.e., 207 companies) data, Google Trends data, and regional variables covering the period from 2009 to 2017. We show that Romanian wine exports, at the firm level, are positively affected by regional wine yields (especially in the case of red wine varieties), temperature, and firm agglomeration, and negatively impacted by firm size. We also find a close positive correlation between financial performance and exports. (JEL Classifications: F61, L66, C23)
