Hydrogen in -iron: Stress and diffusion

First-principles density-functional theory has been used to investigate equilibrium geometries, total energies, and diffusion barriers for H as an interstitial impurity absorbed in -Fe. Internal strains/stresses upon hydrogen absorption are a crucial factor to understand preferred absorption sites and diffusion. For high concentrations, H absorbs near the octahedral site favoring a large tetragonal distortion of the bcc lattice. For low concentration, H absorbs near the tetrahedral site minimizing the elastic energy stored on nearby cells. Diffusion paths depend on the concentration regime too; hydrogen diffuses about ten times faster in the distorted bodycentered-tetragonal bct lattice. External stresses of several GPa modify barriers by 10%, and diffusion rates by 30%.
Implementation and Evaluation of Object Identification Techniques on Nao Robot Platform

nteraction and communication of children with Autism with a humanoid robot would improve their social and verbal interactions and the quality and the speed of the robot in doing interactions will influence the rate of patient health improvement. In this paper, a system is proposed in which the conversion of image into natural language is deployed on Nao humanoid robot as the performance is improved. Actually in this method an image is shown to the robot and it would recognize the shape of the image straight off and say the quantity and type of them using its voice system. In each step of this system several algorithms would be tested and based on results comparison from the error, speed and accuracy point of view, a combination of most optimal of them will be used in proposed algorithm. At last the algorithm is deployed on the humanoid robot and had better results in accuracy and speed than the robot default mode was obtained. This system operated successfully in 95.7 percent of test images and has 14 percent improvement than the default mode.
Transcellular translocation of Campylobacter jejuni across human polarised epithelial monolayers

The mechanisms whereby Campylobacter jejuni translocates across the host intestinal epithelium are not yet understood and the transepithelial route remains undefined. During C. jejuni translocation, the transmonolayer electrical resistance (TER) across polarised monolayers of Caco-2 cells is not affected and the penetration of [14C]inulin across the monolayers does not increase. Over 24 h, however, bacteria damage the monolayer integrity, causing a decrease in the TER. These results support C. jejuni translocation through the cytoplasm of invaded cells (transcellular) rather than via intercellular spaces (paracellular).
The effect of substituting fishmeal with poultry by‐product meal in diets for Totoaba macdonaldi juveniles

Four diets were formulated to evaluate the partial to total substitution of fishmeal with poultry by-product meal (PBM) (0, 33, 67 and 100PBM) in diets for totoaba juveniles (Totoaba macdonaldi). Amino acid profiles from diets and fatty acid content in diets and muscle tissue were used to assess the fish performance using PBM as fishmeal replacement. Stable isotopes of nitrogen (δ15N) were measured in muscle and liver tissue to quantify the retention of each protein source. At the end of the experimental period, the fish fed the 67PBM diet had a significantly higher growth gain increase compared to the other treatments (almost 2000% over an 86 days period; TGC of 1.06). The total replacement of fishmeal with PBM led to low growth gain increase (ca. 220% over 72 days; TGC of 0.52) and increased mortality. Both fish performance and tissues' fatty acid composition suggest that the 100PBM diet was deficient in essential fatty acids. An isotope-mixing model applied to isotope ratios of muscle and liver tissues of fish fed the 67PBM tissues indicated that PBM was retained into muscle and liver tissue in a higher proportion than its level of inclusion in the diet. We conclude that PBM is a good source of nutrients for totoaba juveniles when used in up to 67% fishmeal replacement level in diets containing 52% protein leading to adequate growth rate and survival.
Calculation of collated indices of abundance of butterflies based on monitored sites

Abstract. 1 The Butterfly Monitoring Scheme uses regular transect counts on fixed sites to establish annual indices of abundance of butterfly species in the United Kingdom. The annual change in collated index for each species has hitherto been calculated as a simple ratio between total counts summed over all participating sites. 2 A revised method for calculation of collated indices is proposed, which applies a logarithmic transformation to site values so as to downweight the influence on the index of the sites with greatest numbers of a species. Zero counts are handled comparably with non‐zero values. An alternative method using geometric mean ratios is also examined. 3 Indices calculated using the logarithmic transformation are compared with those calculated using the traditional method. Two internal tests of dependency of collated indices on the sites with highest abundance are made. Another evaluation uses regression analysis for the effects of temperature and rainfall on collated indices of butterfly abundance. 4 The first internal test shows that logarithmic transformation reduces the dependence of the collated index on the sites of highest abundance for twenty‐five out of twenty‐seven species examined; while a second test shows a reduction for twenty‐six out of forty‐two species, and an increase for one species. The number of significant regressions on temperature variables increases with the use of the logarithmic transformation from 11% to 13% of tests made, and on rainfall from 10% to 11%. 5 The geometric mean ratio method introduces considerable biases in its treatment of zero values, for which a remedy is not available. 6 Although the revised collated indices calculated using logarithmic transformation are broadly comparable with traditionally calculated values, the reductions in dependency on sites with the most abundant populations render the revised indices less subject to perturbation due to local ‘noise’, and so more suitable for research on factors influencing butterfly abundance.
INVESTIGATION OF THE SHARPLESS ASYMMETRIC AMINOHYDROXYLATION WITH C-ALLYL GLYCOSIDES

We have studied the Sharpless asymmetric aminohydroxylation on C-allyl glycosides in order to prepare C-glycosyl aminoacids or C-glycopeptides. The perbenzylated amino α-C-allyl glucoside 1 and β-C-allyl glucoside 2 were shown to be moderate substrates for this reaction. New C-glycosyl α-amino ketones were isolated after oxidation of the crude β-amino alcohols.
Improved Text Classification using Long Short-Term Memory and Word Embedding Technique

Text classification is an important problem for spam filtering, sentiment analysis, news filtering, document organizations, document retrieval and many more. The complexity of text classification increases with a number of classes and training samples. The main objective of this paper is to improve the accuracy of text classification with long short-term memory with word embedding. Experiments conducted on seven benchmark datasets namely IMDB, Amazon review full score, Amazon review polarity, Yelp review polarity, AG news topic classification, Yahoo! Answers topic classification, DBpedia ontology classification with different number of classes and training samples. Different experiments are conducted to evaluate the effect of each parameter on LSTM. Results show that 100 batch size, 50 epochs, Adagrad optimizer, 5 hidden nodes, 100-word vector length, 2 LSTM layers, 0.001 L2 regularization, 0.001 learning rate give the higher accuracy. The results of LSTM are compared with literature. For IMDB, Amazon review full score, Yahoo! Answers topic classification dataset the results obtained are better than literature. Results of LSTM for Amazon review polarity, Yelp review polarity, AG news topic classification are close to best-known results. For DBpedia ontology classification dataset the accuracy is more than 91% but less than best known.
Нolistic and Analytic Processing of Facial Expressions: A Method of Multidimentional Scaling

Contemporary scientific literature is controversial about the two basic mechanisms that play a significant role in the identification and discrimination of facial expressions, that is, the analytic process (perceiving individual facial features) and the holistic process (perceiving the face as a Gestalt). Despite the large number of studies, the question of their relative contributions into the perception of facial expressions remains open. In the present study, we investigated the interaction of the analytic and holistic processing simultaneously using the methods of composite and inverted faces in the task of assessing the expression similarity. To achieve this goal, the method of multidimensional scaling was used to enable the construction of a subjective space of expression similarities and then to analyze the clustering of expressions under up-right and inverted exposure conditions. The results showed that: 1. In up-right conditions of face presentations holistic processing plays a more important role; 2. Under the inverted conditions, the role of analytic processing is increased that is manifested in a change of expression clustering in the subjective space of expression similarities; 3. The method of multidimensional scaling is productive for investigating the interaction of analytic and holistic encoding mechanisms of facial expressions; 4. Sharing methods of the composite and inverted faces is an effective tool for changing the impact of analytic and holistic processes in assessing expression similarities.
Altered patterns of soil carbon substrate usage and heterotrophic respiration in a pine forest with elevated CO2 and N fertilization

To assess how heterotrophic microorganisms may alter their activities and thus their CO2‐C return to the atmosphere with elevated CO2 and changing N availability, we examined soil organic matter (SOM) dynamics at the Duke Free Air Carbon Enrichment (FACE) site, after N fertilizer was applied. We measured heterotrophic respiration during early and late stages of SOM mineralization in soil incubations to capture activity on relatively labile and refractory SOM pools. We also measured δ13C of respired CO2‐C and phospholipid fatty acids (PLFAs) during early mineralization stages to track the microbial groups involved in substrate use. We calculated , a measure of δ13CPLFA normalized by respired δ13CO2, to assess microbial function with C substrates formed with elevated CO2 and altered N availability, via the distinct δ13C of the supplemental CO2. We also quantified extracellular enzyme activity (EEA) during labile and recalcitrant SOM mineralization. Early in the incubations, increased N availability reduced heterotrophic CO2‐C release. By the later stages of SOM mineralization, elevated CO2 soils with fertilization had respired 72% of the CO2‐C respired by all other soils. values suggest that fungi in elevated CO2 plots took up C substrates possessing the δ13C signature of recently formed SOM, and added N promoted the activity of Gram‐negative bacteria and reduced that of Gram‐positive bacteria, particularly actinomycetes. Consistent with this, the enzyme responsible for the degradation of peptidoglycan and chitin, compounds produced by Gram‐positive bacteria and fungi, respectively, experienced a decline in activity with N fertilization. If patterns observed in this study with N additions are reversed with progressive N limitation at this site, actinomycetes and other Gram‐positive bacteria responsible for mineralizing relatively recalcitrant substrates may experience increases in their activity. Such shifts in microbial functioning may result in increased turnover of, and C release from, relatively decay‐resistant material.
PREDICTING PRESENCE AND ABUNDANCE OF A SMALL MAMMAL SPECIES: THE EFFECT OF SCALE AND RESOLUTION

Management of small mammal communities in forest ecosystems requires a working knowledge of the scales at which species presence and abundance can best be predicted. Habitat-based models were developed to characterize the distribution of a boreal relict, the southern red-backed vole, Clethrionomys gapperi, in the southern Appalachian Mountains, USA, at three hierarchical scales of analysis. Vole presence and abundance were most evident at the high-resolution (macrohabitat) scale, followed by the intermediate-resolution scale. The low-resolution model was the least effective for predicting presence or abundance and reflects the need for more resolute landscape classification systems if small mammal populations are to be accounted for in an ecologically relevant manner. Tree and shrub communities indicative of suitable vole habitat included Fraxinus pennsylvanica and Tsuga canadensis in the canopy and Carpinus caroliniana in the understory. Vole abundance increased with incidence of tree species such as Bet.
Large‐scale spatial dynamics of a specialist plant pathogen in a fragmented landscape

1 Spatial population structure may have profound consequences for the stability and evolution of host–pathogen interactions. We used a large‐scale 4‐year dataset to study the spatial dynamics of Podosphaera plantaginis, an obligate pathogen of Plantago lanceolata in the Åland Islands in south‐west Finland, where the host populations are mostly very small and have a scattered spatial distribution. 2 The fraction of host populations infected was low but highly variable among years, ranging from 1% to 4.7%, with frequent local extinction and colonization events. Demographic stochasticity associated with regular seasonal declines and severe drought was responsible for the high extinction rate. Frequent colonizations of host populations close to the pathogen source populations suggest that there is substantial gene flow in the pathogen at spatial scales up to 1 km. 3 Occurrence of the pathogen was strongly and positively correlated with the logarithm of host population size, the proximity of a road to the host population (presumably facilitating dispersal) and the proximity of the coastline (presumably due to microclimatic conditions favouring pathogen development). 4 The high turnover rate of the pathogen, distance‐dependent dispersal and regional variation in host–pathogen encounter rates have consequences for the coevolutionary dynamics between Plantago lanceolata and Podosphaera plantaginis.
Consumer Awareness of Medical Internet Marketing Services

This study is designed to empirically verify consumer acceptance and satisfaction of ‘Hospital Marketing Activity’, the most widely used of medical marketing. For this purpose, 26 subjects set out in the medical service were classified as ‘insurance course’ and ‘noninsurance course’. As for the process of consumers accepting the hospital’s Internet marketing activities, the empirical analysis was conducted based on the ‘Technical Acceptance Model’, a typical theoretical model on acceptance of the technology, and the analysis was conducted using the structural modality model. The study found that consumers felt more comfortable with marketing activities for ‘non-insurance courses’, intended to accept internet marketing, and that satisfaction also had a positive effect. On the other hand, Internet marketing in the field of ‘insurance courses’ was able to confirm that convenience, rather than usefulness, had a prior impact on marketing acceptance. These results have allowed us to infer that, in the case of an essential health care subject, a marketing strategy that allows consumers to feel useful rather than aggressive marketing activities. In contrast, it concluded that for ‘non-insured subjects’ such as skin-soluble type, health examination, and health promotion programs, it was effective to focus on more aggressive marketing activities that enhance the professionalism of medical.
Psychological, Social and Emotional Well-Being of Adults with a History of Institutionalization: The Pilot Study Findings

The paper presents pilot research data that is part of the research project “The Impact of Early Deprivation on the Bio-Behavioral Indicators of Child Development” from the Government’s megagrant programs No. 14.Z50. 31.0027. The purpose of the paper is the study of mental, social and emotional well-being indicators of adults raised in orphanages in comparison with a control group of adults who grew up in biological families. The comparison was carried out using scales of the WHO Questionnaire for assessing quality of life and Adult Self-Report (ASR) from The Achenbach System of Empirically Based Assessment (ASEBA) for assessing psychological and emotional well-being. Results revealed no significant differences between the groups studied. However, using the classification procedures, we found that an important feature is the living conditions that enable classification of membership in a group of graduates of an orphanage or in a group of adults from biological families: a separate apartment or a “public” space (a communal apartment or a dorm). A hypothesis has been put forward about the impact of the current living environment on the diagnosed indicators of the mental, social and emotional well-being of orphanage graduates.
Encyclical Laudato si’ on the Question of Progress

Progress is one of the most recognizable characteristics of modern times. The present paper addresses the question of progress as the underlying theme of the encyclical Laudato si’. Progress has both good and bad sides. The latter are expressed in terms that have a fundamental significance to the encyclical, such as, “irrational faith in progress” and “the myth of unlimited material progress”. In order to gain a clearer understanding of those terms, the author begins with outlining the history of the idea of progress and the philosophical criterion for its assessment. Then, he provides a critical analysis of the technocratic paradigm embodying the false face of progress. Within this framework, progress is presented as imperative and unlimited. However, by placing man in the centre and reducing his purpose in life to a relativistic principle “use and throw away”, it leads to a global ecological, spiritual and cultural crisis. The following part of the paper is devoted to a new model of progress proposed by Pope Francis. This type of progress has both a vertical and horizontal dimension. Embedded in the Holy Trinity, it reaches its peak in Jesus Christ and it promotes human life and protects the work of creation. Its fruit is to be individual concern for the poor and greater justice between nations. It cannot be achieved without changing the mentality (conversion) and specific individual and political decisions. The last part of the article answers the question about the novelty of the model of progress proposed by Pope Francis.
Specific ornamentation of orbicular walls and pollen grains, as exemplified by Acanthaceae

For the first time in Acanthaceae a comparative study of orbicules forming stable, coherent orbicular walls and the respective pollen ornamentation was undertaken. A peculiar acetolysis resistant, often species specific orbicular wall is typical for many genera. In some cases the orbicular wall ornamentation resembles closely the pollen ornamentation, in others it differs to a variable degree. The presumed function of orbicular walls is discussed.
Quality of light and indolbutyric acid in vitro rooting of lavender

Lavender, an aromatic and medicinal plant, used in the extraction of essential oil, as an ornamental and meliferous plant, can be successfully propagated as long as the light, the nutrient medium and the growth regulators are adequate. The aim of the study was to evaluate the effect of different concentrations of indolebutyric acid (IBA) associated to distinct light spectra, on the in vitro rooting of Lavandula angustifolia . The experiment consisted in the combination of two concentrations of indolebutyric acid in the growth medium (0 and 0.1 mg L-1) and two light spectra, using cellulose acetate filters (blue and red), besides the control (without filter), totaling six treatments with four repetitions. For each repetition five explants were used. After 30 days, the variables evaluated were: survival percentage, number of buds and leaves, shoot length, number of roots, length of the longest root, shoot fresh and dry matter weight. There was a significant interaction among the indolebutyric acid concentrations and the light filters for the variables number of buds, leaves and roots and shoot length. Except for leaf number, promising results were obtained when the explants were held under red filters and with a concentration of 0 mg L-1 of indolebutyric acid in the growth medium. From these results, it can be concluded that the best in vitro rooting of Lavandula angustifolia is obtained when there is no indolebutyric acid in the growth medium associated with the use of the red filter.
Neural Network based Network Traffic Predictability for IoT Environment

The purpose of this paper is to predict of compare network changes using neural networks. Many devices operate for various purposes using network technology, but unmanaged network environments cause packet loss for a variety of reasons. This packet loss causes data retransmissions and delays, and in environment where limited battery or limited network resources must be utilized, various problems can occur. Experiments show how neural networks can be used to predict network changes and whether they can predict changes in real networks. Predictability of Network Traffic indicates that LSTM (Long Short-Term Memory) is higher than MLP (Multi-Layer Perceptron).
Cultivation of Sweet Marjoram, Marjorana hortensis,in Newly Reclaimed Lands of Egypt

Sweet marjoram (Marjorana hortensis Moench) is cultivated in Egypt as biennial plant for the leaves and essential oil that are used in the food and pharmaceutical industries. The cultivation of sweet marjoram in newly reclaimed land under a sprinkler irrigation system yielded 94 percent of leaf yield observed in loamy soils and was superior in the oil content. Harvests in October gave the highest leaf and oil yields. The main plant constituents of marjoram in newly reclaimed lands were similar with the constituents of plants cultivated in loamy land.
