ConSet: Hierarchical Concurrent Path Setup Scheme in Multi-Layer GMPLS Networks

SUMMARY This letter proposes a hierarchical label-switched path (LSP) setup scheme, called ConSet, for multi-layer generalized multiprotocol label switching (GMPLS) networks. ConSet allows a Path message to be transmitted to the downstream neighbor node without waiting for the establishment of the higher-order LSP. Confirmation of the establishment of the higher-order LSP is performed at the ingress node of the higher-order LSP before a Resv message of the lower-order LSP is transmitted to the upstream neighbor node. ConSet is able to set up hierarchical LSPs faster than the sequential scheme.
Isolation of Antioxidant Compounds from Aspergillus Terreus LS01

The antioxidative activity of an ethyl acetate extract from Aspergillus terreus LS01was evaluated using various in vitro assays: 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydrogen-peroxide-scavenging free radical scavenging, and β-caroten-linoleat model assay and the antioxidants in the extract were isolated and identified. Silica gel column chromatography was used to separate the extract into five fractions (F1-F5). Fraction 3 possessed significant antioxidative activity with an IC 50 of 19. 91μg/ml. Fraction 3 was further separated by column chromatography and yielded the crystalline compounds 1 and 2, which were identified as terreic acid and terremutin, respectively, on the basis of UV-vis spectra, MS and NMR analyses. Terreic acid and terremutin exhibited the highest level of DPPH free radical scavenging activity with IC 50 values of 0.115±4.02 and 0.114±2.19 mM, respectively. These compounds also showed scavenging activity of hydrogen peroxide radicals which terreic acid exhibited higher than terremutin with 74.07±1.48% and 33.74±2.81% respectively. In the β-caroten-linoleat model assay, the inhibition of terreic acid retained 26.01±1.14% and terremutin retained 32.29±2.23%. This is the first report on antioxidative activity of terreic acid and terremutin from A.terreus . The findings indicated that A. terreus could be considered as potential source of natural antioxidant products.
Optimisation of Neural Network with Simultaneous Feature Selection and Network Prunning using Evolutionary Algorithm

Most advances on the Evolutionary Algorithm optimisation of Neural Network are on recurrent neural network using the NEAT optimisation method. For feed forward network, most of the optimisation are merely on the Weights and the bias selection which is generally known as conventional Neuroevolution. In this research work, a simultaneous feature reduction, network pruning and weight/biases selection is presented using fitness function design which penalizes selection of large feature sets. The fitness function also considers feature and the neuron reduction in the hidden layer. The results were demonstrated using two sets of data sets which are the cancer datasets and Thyroid datasets. Results showed backpropagation gradient descent error weights/biased optimisations performed slightly better at classification of the two datasets with lower misclassification rate and error. However, features and hidden neurons were reduced with the simultaneous feature /neurons switching using Genetic Algorithm. The number of features were reduced from 21 to 4 (Thyroid dataset) and 9 to 3 (cancer dataset) with only 1 hidden neuron in the processing layer for both network structures for the respective datasets. This research work will present the chromosome representation and the fitness function design.
A STOCHASTIC SHAPE AND ORIENTATION MODEL FOR FIBRES WITH AN APPLICATION TO CARBON NANOTUBES

Methods are introduced for analysing the shape and orientation of planar fibres from greyscale images of fibrous systems. The sequence of image processing techniques needed for segmentation of fibres is described. The identified fibres were interpreted as deformed line segments for which two shape and two orientation parameters are estimated by the maximum likelihood method. The methods introduced are shown to perform quite well for simulated systems of deformed line segments with known properties. They were applied to TEM images of carbon nanotubes embedded in polycarbonate.
Microscopic Characterization of a Transposon-Induced Male-Sterile, Female-Sterile Mutant in Glycine max L.

Premise of research. A male-sterile, female-sterile mutant was discovered in a w4-m mutable line of Glycine max L. The mechanism of its sterility was not well understood. Therefore, different cytological and microscopic techniques were undertaken to better understand the process of mutant phenotype development. Molecular research indicated that mer3 was responsible for the sterility. Methodology. Macro images were collected of whole plants, flowers, anthers, pods, and ovules. Chromosome spreads from anthers at various meiotic stages were examined. Confocal scanning laser microscopy using optical sectioning was utilized on whole anthers and ovules at various developmental stages. Whole mature anthers and isolated pollen images were collected and studied with SEM. Pivotal results. In observations of the mutant, male cell development was found to begin normally and then digresses at metaphase I of meiosis, when abnormal segregation of chromosomes with reduced bivalent formation was observed. It was the abnormal formation of univalents and bivalents that led to male sterility. On the female side, the progression of development was arrested in the megagametophyte stage likely because of abnormal meiosis, leading to ovule abortion and female sterility. Conclusions. The G. max male-sterile, female-sterile mutant was shown to have the same phenotype of mer3 sterility already shown in Arabidopsis, rice, yeast, and some animal systems.
THE IMPACT OF SERVICE QUALITY ON BEHAVIORAL INTENTION IN HOSPITALITY INDUSTRY

The purpose of this study is to determine the impact of service quality on behavioral intention in hospitality industry. In order to measure service quality, five-dimensional and twenty two-itemed scale which adapted for hospitality industry by Tsaur, Lin and Wu from Parasuraman, Zeithaml and Berry’s SERVQUAL scale, was used. Together with this scale, five-dimensional and thirteenitemed scale which developed by Parasuraman, Zeithaml and Berry was used in order to measure behavioral intention. This study was performed in five star hotels in Belek Tourism District in Antalya, and 610 questionnaire forms were returned out of 1000 distributed ones. According to the results of the study, the correlation values related with the dimensions of service quality and behavioral intention are found varying between 0.245 and 0.821. In the path analysis, with which, examining the impact of service quality on behavioral intention was aimed; we found that the service quality has more impact on the behavioral dimensions of “loyalty” and “pay more”.
EXPRESSION OF A SESAME GERANYLGERANYL REDUCTASE cDNA IS INDUCED BY LIGHT BUT REPRESSED BY ABSCISIC ACID AND ETHYLENE

Geranylgeranyl reductase (CHL P) is localized in plastids and catalyzes the reduction of geranylgeranyl diphosphate to phytyl diphosphate, a molecule required for both tocopherol and chlorophyll biosyntheses. To understand the regulation of Chl P expression in sesame, a Chl P cDNA (SiChlP) was isolated and the effects of light and phytohormones on SiChl P expression was investigated. The putative SiChl P cDNA was 1,633 bp and included a 1,394 bp open reading frame encoding a polypeptide of 465 amino acid residues. SiChl P mRNA was expressed most abundantly in leaves and cotyledons, moderately in developing capsules and seeds, but little in flowers, hypocotyls and roots of healthy seedlings and plants. Expression of SiChl P in a cotyledon was induced by light, but the level of induction was higher in red light than in far-red or blue light. However, SiChl P expression was diminished by dark, ethylene and abscisic acid.
Population Dynamics of Native Parasitoids Associated with the Asian Chestnut Gall Wasp (Dryocosmus kuriphilus) in Italy

Native parasitoids may play an important role in biological control. They may either support or hinder the effectiveness of introduced nonnative parasitoids released for pest control purposes. Results of a three-year survey (2011–2013) of the Asian chestnut gall wasp (ACGW) Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) populations and on parasitism rates by native indigenous parasitoids (a complex of chalcidoid hymenopterans) in Italian chestnut forests are given. Changes in D. kuriphilus gall size and phenology were observed through the three years of study. A total of 13 species of native parasitoids were recorded, accounting for fluctuating parasitism rates. This variability in parasitism rates over the three years was mainly due to the effect of Torymus flavipes (Walker) (Hymenoptera: Torymidae), which in 2011 accounted for 75% of all parasitoid specimens yet decreased drastically in the following years. This strong fluctuation may be related to climatic conditions. Besides, our data verified that parasitoids do not choose host galls based on their size, though when they do parasitize smaller ones, they exploit them better. Consequently, ACGWs have higher chances of surviving parasitism if they are inside larger galls.
AN INNOVATIVE TECHNIQUE TO DECONTAMINATE ACTIVATED SLUDGE INCREASING ANAEROBIC DIGESTION PERFORMANCE

Electroosmotic dewatering of activated sludge is an important transport processes playing a critical role in electroosmotic dewatering of sludge. In the present work a comprehensive physical model considering both pressure-driven and electroosmosis-driven flows in an activated sludge floc was developed and numerically solved. Meshes were produced via scanning images based on real sludge flocs. The permeabilities of pressure and electroosmotic flows were evaluated, from which the total detwatering flow rate can be estimated.
A possible signature of terrestrial planet formation in the chemical composition of solar analogs

Recent studies have shown that the elemental abundances in the Sun are anomalous when compared to most (about 85%) nearby solar twin stars. Compared to its twins, the Sun exhibits a deficiency of refractory elements (those with condensation temperatures Tc>900K) relative to volatiles (Tc<900K). This finding is speculated to be a signature of the planet formation that occurred more efficiently around the Sun compared with the majority of solar twins. Furthermore, within this scenario, it seems more likely that the abundance patterns found are specifically related to the formation of terrestrial planets. In this work we analyze abundance results from six large independent stellar abundance surveys to determine whether they confirm or reject this observational finding. We show that the elemental abundances derived for solar analogs in these six studies are consistent with the Tc trend suggested as a planet formation signature. The same conclusion is reached when those results are averaged heterogeneously. We also investigate the dependency of the abundances with first ionization potential (FIP), which correlates well with Tc. A trend with FIP would suggest a different origin for the abundance patterns found, but we show that the correlation with Tc is statistically more significant. We encourage similar investigations of metal-rich solar analogs and late F-type dwarf stars, for which the hypothesis of a planet formation signature in the elemental abundances makes very specific predictions. Finally, we examine a recent paper that claims that the abundance patterns of two stars hosting super-Earth like planets contradict the planet formation signature hypothesis. Instead, we find that the chemical compositions of these two stars are fully compatible with our hypothesis.
MAGNETOHYDRODYNAMIC SHOCKS IN AND ABOVE POST-FLARE LOOPS: TWO-DIMENSIONAL SIMULATION AND A SIMPLIFIED MODEL

Solar flares are an explosive phenomenon where super-sonic flows and shocks are expected in and above the post-flare loops. To understand the dynamics of post-flare loops, a two-dimensional magnetohydrodynamic (2D MHD) simulation of a solar flare has been carried out. We found new shock structures in and above the post-flare loops, which were not resolved in the previous work by Yokoyama & Shibata. To study the dynamics of flows along the reconnected magnetic field, the kinematics and energetics of the plasma are investigated along selected field lines. It is found that shocks are crucial to determine the thermal and flow structures in the post-flare loops. On the basis of the 2D MHD simulation, we developed a new post-flare loop model, which we defined as the pseudo-2D MHD model. The model is based on the one-dimensional (1D) MHD equations, where all variables depend on one space dimension, and all the three components of the magnetic and velocity fields are considered. Our pseudo-2D model includes many features of the multi-dimensional MHD processes related to magnetic reconnection (particularly MHD shocks), which the previous 1D hydrodynamic models are not able to include. We compared the shock formation and energetics of a specific field line in the 2D calculation with those in our pseudo-2D MHD model, and found that they give similar results. This model will allow us to study the evolution of the post-flare loops in a wide parameter space without expensive computational cost or neglecting important physics associated with magnetic reconnection.
Informality meets Formality: When Management’s and Employees’ Practices of Knowledge Sharing Diverge

Knowledge sharing, as a significant part of knowledge management, is a difficult but important objective for organisations to achieve. Previous research in this field calls for more attention to knowledge sharing in an organisational context and studies of the means and consequences of management’s and employees’ diverging practices. Answering this call, the following article is based on a case study at Smart Planning Solutions AB, a Swedish IT service providing company. This study shows that knowledge sharing among employees mainly occurs within communities of practice. Moreover, we find that management wants knowledge sharing to take place formally via guidelines, IT systems and meetings, while employees adapt given instructions and share knowledge informally. These diverging practices lead to a paradox. We argue that employees need formal managerial tools which they de-formalise in order to share knowledge informally with each other. We found that de-formalisation is done in three ways: transformation, extraction and avoidance. This study shows that management can influence knowledge sharing, but not the way knowledge is shared among employees.
Deveríamos buscar confiabilidade inter-avaliadores ou diversidade? Um estudo empírico sobre a avaliação do desempenho de pilotos

Reliably and equitably assessing the performance of commercial pilots has not always proven easy. It is thus necessary to take a closer look on how performance is assessed in practice. This study explores the reasoning behind this process as stated by experienced pilots who assess safe- ty-critical pilot performance. Using a theoretical model of performance, three pairs of airline captains assessed a captain and a first officer in two video scenarios. The results show that assessors apply the same or similar reasons to arrive at different assessments or use different reasons to arrive at the same assessment. In addition, conclusions about inter-rater reliability and efforts intended to increase it are drawn.
Application of Tuning Fork Sensors for In-situ Studies of Dynamic Force Interactions Inside Scanning and Transmission Electron Microscopes

Mechanical properties of nanoscale contacts have been probed in-situ by specially developed force sensor based on a quartz tuning fork resonator (TF). Additional control is provided by observation of process in scanning electron microscope (SEM) and transmission electron microscope (TEM). A piezoelectric manipulator allows precise positioning of atomic force microscope (AFM) probe in contact with another electrode and recording of the TF oscillation amplitude and phase while simultaneously visualizing the contact area in electron microscope. Electrostatic control of interaction between the electrodes is demonstrated during observation of the experiment in SEM. In the TEM system the TF sensor operated in shear force mode: Use of TEM allowed for direct control of separation between electrodes. New opportunities for in situ studies of nanomechanical systems using these instruments are discussed. DOI: http://dx.doi. org/10.5755/j01.ms.18.2. 1927
Does student proactivity guarantee positive academic results

This paper analyzes the impact of students’ proactivity on academic performance based on a sample from students enrolled in an introductory course of Political Economy at the University of Seville (Spain) in three consecutive courses (2014–2015, 2015–2016 and 2016–2017). Proactivity is measured by several indicators, such as class attendance, case-study oral presentation and its delivery in a foreign language, all of them being non-mandatory activities for students who have participated in the experiment. Specifically, this study aims to assess the impact of a student’s proactivity on two academic outcomes: (i) to pass or fail the exam; and (ii) the score obtained. Impact assessment has been performed using a probit and ordered multinomial logit models. The results show that a student’s proactivity measured by class attendance and case-study presentation significantly increases the probability of passing the exam, while the impact of using a foreign language seems to be non-significant. In relation to the score obtained, the proactivity measured through the case presentation raises the probability of obtaining a higher mark more than regular class attendance.
Interpersonal and Societal Aspects of Use Conflicts A Case Study of Wilderness in Alaska and Finland

Wilderness conflicts in Finland and Alaska are multifaceted, with recreation uses increasingly conflicting with subsistence activities. To investigate these conflicts, over 70 interviews were conducted with subsistence users, representatives from guide companies, local residents, land managers, and nongovernmental organizations in Alaska and Finland. While goal interference and scarcity of resources are factors in many conflicts, social and cultural factors (e.g., traditional values and rights issues) play important roles too. Conflicts that appear at first to be direct and tangible may be symptoms of underlying societal, judicial, and philosophical conflicts.
The chemical composition and meat yield of sexually mature cuttlefish (Sepia officinalis).

The objective of the present study was to determine the chemical composition and meat yield for both sexes of adult cuttlefish, Sepia officinalis, in the Mersin Bay, East Mediterranean. The results of meat yield showed that meat yield of adult male cuttlefish were higher than those of the female. The levels of protein ranged from 22.15% to 22.20%, lipid from 0.86% to 1.01%, and water from 74.97% to 75.30%, total mineral substance (TMS) from 1.68% to 1.69% for mantle of female and male cuttlefish. Moreover, there were not variations in protein, lipid, water and TMS content of mantle tissues of both adult females and males (p>0.05). The levels of saturated fatty acids (SFA) ranged from 29.49% to 29.88%, monounsaturated fatty acids (MUFAs) from 10.97% to 11.40%, and polyunsaturated fatty acids (PUFAs) from 52.27% to 53.42% for both of the sexes. In the present study, the major fatty acids found in S. officinalis were palmitic acid (C16:0), stearic acid (C18:0), eicosapentaenoic acid (EPA, C20:5 n-3) and docosahexaenoic acid (DHA, C22:6 n-3). Statistically, there were no significant differences in DHA concentrations in mantle tissue of male and female cuttlefish (p>0.05). Besides, EPA concentrations in mantle of female cuttlefish were higher than those of the male (p 0.05). Cu content of female cuttlefish was significantly higher (p<0.05) than that found in male cuttlefish.
On the Connection between Neural Processes and Gaussian Processes with Deep Kernels

In this paper, we establish an explicit theoretical connection between NPs and GPs. In particular, we show that, under certain conditions, NPs are mathematically equivalent to GPs with deep kernels. This result further elucidates the relationship between GPs and NPs and makes previously derived theoretical insights about GPs applicable to NPs. Furthermore, it suggests a novel approach to learning expressive GP covariance functions applicable across different prediction tasks by training a deep kernel GP on a set of datasets [3, 7, 9, 10].
Consensus Analysis for a Class of Heterogeneous Multiagent Systems with Time Delay Based on Frequency Domain Method

The consensus problem of heterogeneous multiagent systems composed of first-order and second-order agent is investigated. A linear consensus protocol is proposed. Based on frequency domain method, the sufficient conditions of achieving consensus are obtained. If communication topology contains spanning tree and some conditions can be satisfied on control gains, consensus can be achieved. Then, a linear consensus protocol with time delay is proposed. In this case, consensus is dependent only on system coupling strength, each agent input time delay, but independent of communication delay. Finally, numerical simulations are provided to illustrate the effectiveness of the theoretical result.
