EPIDEMIC SPREADING IN ADAPTIVE MULTILAYER NETWORKS

Adaptive networks, which combine topological evolution of the network with dynamics on the network, are ubiquitous across disciplines. Examples include technical distribution networks such as road networks and the internet, natural and biological networks, and social science networks. These networks often interact with or depend upon other networks, resulting in multilayer adaptive networks. We study susceptible-infected-susceptible (SIS) epidemic dynamics on such networks revealing a new stable state which only emerges in the case of weakly coupled networks [5]. In this state, the disease is endemic in one network but neither becomes endemic nor dies out in the other. Instead, it persists only at the interconnected nodes and does not break out into the wider network.
Collision Detection and Control of Parallel-Structured Flexible Manipulators Based on Unscented Kalman Filter

Flexible manipulators that are lightweight and mechanically flexible are useful for operations in various fields, e.g. space development programs, robotic assistants to humans and so forth. However, the derivation of their exact mathematical model and synthesis of the accurate positioning controller is exceptionally difficult because of the mechanical flexibility. On the other hand, the mechanical flexibility is conducive to the safety in collision between the manipulator and the obstacles. However, it is not positive safety measures that reduction of the influence due to the impact force of collision for the flexible manipulator depends only on its mechanical flexibility. In order to develop flexible manipulators so that they work safely with persons cooperatively, we need to introduce the active collision detection and suspension control algorithms to the flexible manipulators. The functional requirements of safety in the operations of flexible manipulators are as follows: i) to avoid collisions with obstacles placed or moving in the work space; ii) to detect collisions when unlooked-for obstacles contact with the flexible arm of the manipulator and to suspend the motion as immediately as possible; iii) to plan a new path so as to avoid the place of obstacles. There are several researches on collision detection methods without extra sensors (A. Garcia & Somolinos, 2003), (M. Kaneko & Tsuji, 1998), (T. Matsumoto & Kosuge, 2000). Moorehead and Wang proposed (Moorehead & Wang, 1996) a collision detection method using strain gauges to determine the intensity and position of external force due to collision with a flexible cantilevered beam. The estimation of the contact position in their approach was achieved by the mechanical relation between positions of the two strain gauges and the bending moments measured by the sensors. Payo et al. (I. Payo & Cortazar, 2009) is produced the method of collision detection and suspend control of the very lightweight single-link flexible arm based on coupling torque feedback. They used the variation of the control torque. The authors have focused our attention on the second item mentioned above. We already developed a method of collision detection for the single-link flexible manipulator using the innovation process of the Kalman filter (Sawada, 2002a), (Sawada, 2002b), (Sawada, 2002c), (Sawada, 2004 (in Japanese)), (Kondo & Sawada, 2008). Our approach requires no particular
H-ATLAS/GAMA and HeViCS – dusty early-type galaxies in different environments

The Herschel Space Observatory has had a tremendous impact on the study of extragalactic dust. Specifically, early-type galaxies (ETG) have been the focus of several studies. In this paper, we combine results from two Herschel studies – a Virgo cluster study Herschel Virgo Cluster Survey (HeViCS) and a broader, low-redshift Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS)/Galaxy and Mass Assembly (GAMA) study – and contrast the dust and associated properties for similar mass galaxies. This comparison is motivated by differences in results exhibited between multiple Herschel studies of ETG. A comparison between consistent modified blackbody derived dust mass is carried out, revealing strong differences between the two samples in both dust mass and dust-to-stellar mass ratio. In particular, the HeViCS sample lacks massive ETG with as high a specific dust content as found in H-ATLAS. This is most likely connected with the difference in environment for the two samples. We calculate nearest neighbour environment densities in a consistent way, showing that H-ATLAS ETG occupy sparser regions of the local Universe, whereas HeViCS ETG occupy dense regions. This is also true for ETG that are not Herschel-detected but are in the Virgo and GAMA parent samples. Spectral energy distributions are fit to the panchromatic data. From these, we find that in H-ATLAS the specific star formation rate anticorrelates with stellar mass and reaches values as high as in our Galaxy. On the other hand HeViCS ETG appear to have little star formation. Based on the trends found here, H-ATLAS ETG are thought to have more extended star formation histories and a younger stellar population than HeViCS ETG.
Development of antioxidant activity and pattern recognition of terminalia chebula retzius extracts and its fermented products

This study was to determine the difference of antioxidant activities between unfermented extracts and fermented products for Terminalia chebula Retzius, and to recognize antioxidative patterns. The methanol extract, water extract, 95 % ethanol extract, fermented product of dried powder at 25 °C and fermented product of residues after 95 % ethanol extraction at 37 °C showed good antioxidant activities based the scavenging effect on 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) assay and the horseradish peroxidase (HRP)-luminol-hydrogen peroxide (H_2O_2) assay, respectively. The methanol extract, water extract, 95 % ethanol extract, fermented product of dried powder at 15 °C and fermented product of water extract at 25 °C exhibited a good value of antioxidant activity based on the pyrogallol-luminol assay. The antioxidative pattern plots revealed valuable information and showed good correlation between scavenging effect on DPPH radical assay and HRP-luminol-H_2O_2 assay. These results may represent promising plant-sources of medicine in the future.
Reflectance measurement of canopy biomass and nitrogen status in wheat crops using normalized difference vegetation indices and partial least squares regression

Hyperspectral reflectance (438 to 884 nm) data were recorded at five different growth stages of winter wheat in a field experiment including two cultivars, three plant densities, and four levels of N application. All two-band combinations in the normalized difference vegetation index (k1 k2)/(k1 + k2) were subsequently used in a linear regression analysis against green biomass (GBM, g fresh weight m 2 soil), leaf area index (LAI, m green leaf m 2 soil), leaf chlorophyll concentration (Chlconc, mg chlorophyll g 1 leaf fresh weight), leaf chlorophyll density (Chldensity, mg chlorophyll m 2 soil), leaf nitrogen concentration (Nconc, mg nitrogen g 1 leaf dry weight), and leaf nitrogen density (Ndensity, g nitrogen m 2 soil). A number of grouped wavebands with high correlation (R>95%) were revealed. For the crop variables based on quantity per unit surface area, i.e. GBM, LAI, Chldensity, and Ndensity, these wavebands had in the majority (87%) of the cases a center wavelength in the red edge spectral region from 680 to 750 nm and the band combinations were often paired so that both bands were closely spaced in the steep linear shift between Rred and Rnir. The red edge region was almost absent for bands related to Chlconc and Nconc, where the visible spectral range, mainly in the blue region, proved to be better. The selected narrow-band indices improved the description of the influence of all six-crop variables compared to the traditional broadand short-band indices normally applied on data from satellite, aerial photos, and field spectroradiometers. For variables expressed on the basis of soil or canopy surface area, the relationship was further improved when exponential curve fitting was used instead of linear regression. The best of the selected narrow-band indices was compared to the results of a partial least square regression (PLS). This comparison showed that the narrow-band indices related to LAI and Chlconc, and to some extent also Chldensity and Ndensity, were optimal and could not be significantly improved by PLS using the information from all wavelengths in the hyperspectral region. However, PLS improved the prediction of GBM and Nconc by lowering the RMSE with 22% and 24%, respectively, compared to the best narrow-band indices. It is concluded that PLS regression analysis may provide a useful exploratory and predictive tool when applied on hyperspectral reflectance data. D 2003 Elsevier Inc. All rights reserved.
Temporal variability in macroinvertebrates diversity patterns and their relation with environmental factors

Gerami MH, Patimar R, Negarestan H, Jafarian H, Mortazavi MS. 2015. Temporal variability in macroinvertebratesÂ diversity patterns and their relation with environmental factors. Biodiversitas 17: 36-43. Seasonal changes are the most important factorÂ in temporal variability of macroinvertebrates communities in marine benthic zone. Realizing the pattern of these changes are the keyÂ attributes to maintain benthic resources. For this purpose this study aimed to investigate temporal variability of macroinvertebratesÂ diversity patterns in different seasons in Hormozgan province waters, Persian Gulf. Five sites were identified and sampling was carriedÂ out randomly at three places with three replicate in each site from autumn 2014 to spring 2015. Physiochemical properties of water wereÂ recorded in each sampling site. Total of 19 macroinvertebrate orders were identified form four seasons in all sites. Results showed thatÂ Polychaeta were dominant taxa in all seasons and maximum diversity of benthic macroinvertebrates exhibitedin winter. According toÂ evenness index (E1), abundances of species were most balanced in spring. Analysis of weight and density revealed that the species diversity and mean weight of macroinvertebrates had maximum in winter and minimum in summer. Macroinvertebrate community structure was similar in the spring and summer and partly discriminated from remaining two seasons. SIMPER analysis confirmed these dissimilarities and revealed that Foraminifera, Gastropoda and Polychaeta have three major contributions in dissimilarities between seasons. According to BIO-ENV analysis, oxygen and chlorophyll a were the best variables (r = 0.7143) explaining changes in the abundance over time of the benthic fauna under study. On the contrary, eight orders (Amphipoda, Secernentea, Cumacea, Euphausiacea, Gastropoda, Isopoda, Anthozoa and Sagittoidea)Â did not show any convergence with environmental factors in this study.

A Framework for Cross-domain Recommendation in Folksonomies

Even though recommendation systems have achieved great success both in commerce and academy, there is still much to improve in cross-domain recommendation field. In this paper, we propose a novel framework for cross-domain recommendation in folksonomies: CRF. The idea of CRF is generating user's tag-profile in the target domain, based on the correlation of tags between different domains. Then the cross-domain issue is transferred into traditional single domain recommendation problem. Compared to related work, CRF is more flexible and scalable, it can adapt to multi-cross- domain recommendation issues. As it is a framework, CRF can be implemented in various ways according to practical requirements. Moreover, CRF is based on folksonomy, so it can be widely used in various applications of Web 2.0. In addition, data sets from previous work are far from satisfaction, so we build a cross-domain data set for evaluation. We validate different realizations of CRF and demonstrate its effectiveness. The test results show that when we choose typical tags as features, the algorithm performs the best. The experiments also show that CRF is more precise than one-domain recommendation algorithms to solve cold-start problem in the target domain. 
Emotion Based LMS: An Investigation of User Perceptions and Attitudes

This study offers a comprehensive review of various methodologies for emotion based emotion Learning Management Systems (LMS) and examines the use of Technology Acceptance Model (TAM) to investigate how learner beliefs and attitudes influence emotion based LMS use among higher education learners by evaluating the relationships between perceived usefulness, perceived ease of use, attitude and behavioural intentions. In the study, 40 potential users were presented with an introductory demonstration of emotion based LMS for an IT course. Following the demonstration, data on user perceptions and attitudes about emotion based LMS were gathered based on this initial exposure. Hierarchical multiple regressions were used to assess the overall model and influence of each variable of interest in determining behavioural intentions to use emotion based LMS. The analysis showed that both the user perceptions and attitudes have significant positive effects on behavioural intention to use emotion based LMS. Implications of these findings for practice and research are examined and discussed.
MIPO in the Management of Type IIIA Compound Femoral Shaft Fractures Caused by High Velocity Missiles

Background: Compound femoral shaft fractures that caused by high-velocity missiles HVMs (bullets and shells) are very extensive injuries, and still remain one of the greatest challenges to orthopedic trauma surgeons, closed intramedullary locked nail is considered the gold standard treatment modality, but it is not always available or applicable, and conventional plating method of these fractures had Increasing rates of infection, delayed union, nonunion and implant failure. Aim of the study: To evaluate MIPO (The Minimally Invasive Plate Osteosynthesis technique) technique as an alternative procedure to closed intramedullary locked nail in treatment of type IIIA femoral shaft fractures due to HVMs. Patients and methods: This prospective study, from October 2014 to March 2016, included 16 male patient, aged between 22-47 y, 4 patients were civilians and 12 were militaries, with 16 compound femoral shaft fracture of type IIIA (Gustilo-Anderson Classification) that caused by HVMs, 13 fracture were caused by bullets and 3 by shells. All fractures had been treated by early wound debridement and external fixation and one-stage conversion to internal fixation by MIPO technique using long DCP within 2 weeks, when there are no signs of active infection. Results: For all fractures, 4 of 16 fracture (25%) had bony union in 18 week, 10 of 16 fracture (62.5%) had bony union in 24 week, and only 2 of 16 fracture (12.5%) did not have complete bony union at 24 week (delayed union), which had complete healing of the fractures in the next 6 weeks (in 30 week) without secondary surgical intervention. For all fractures, there were no wound healing complications, infections, nonunion or implant failure. Conclusion: MIPO treating HVMs femoral shaft fractures can be used as an alternative procedure to closed intramedullary locked nail.
Minimizing light absorption measurement artifacts of the Aethalometer: evaluation of five correction algorithms

Obtaining a good description of aerosol optical properties for a physically and chemically complex evolving aerosol is computationally very expensive at present. The goal of this work is to propose a new numerical module computing the optical properties for 5 complex aerosol particles at low numerical cost so that it can be implemented in atmospheric models. This method aims to compute the optical properties online as a function of a given complex refractive index deduced from the aerosol chemical composition and the size parameters corresponding to the particles. The construction of look-up tables from the imaginary and the real part of the com10 plex refractive index and size parameters will also be explained. This approach is validated for observations acquired during the EUCAARI campaign on the Cabauw tower during May 2008 and its computing cost is also estimated. These comparisons show that the module manages to reproduce the scattering and absorbing behaviour of the aerosol during most of the fifteen-day period of observation 15 with a very cheap computationally cost.
Aggression Identification and Multi Lingual Word Embeddings

The system presented here took part in the 2018 Trolling, Aggression and Cyberbullying shared task (Forest and Trees team) and uses a Gated Recurrent Neural Network architecture (Cho et al., 2014) in an attempt to assess whether combining pre-trained English and Hindi fastText (Mikolov et al., 2018) word embeddings as a representation of the sequence input would improve classification performance. The motivation for this comes from the fact that the shared task data for English contained many Hindi tokens and therefore some users might be doing code-switching: the alternation between two or more languages in communication. To test this hypothesis, we also aligned Hindi and English vectors using pre-computed SVD matrices that pulls representations from different languages into a common space (Smith et al., 2017). Two conditions were tested: (i) one with standard pre-trained fastText word embeddings where each Hindi word is treated as an OOV token, and (ii) another where word embeddings for Hindi and English are loaded in a common vector space, so Hindi tokens can be assigned a meaningful representation. We submitted the second (i.e., multilingual) system and obtained the scores of 0.531 weighted F1 for the EN-FB dataset and 0.438 weighted F1 for the EN-TW dataset.
EXTRACTING 3 D FROM 2 D : SELECTION BASIS FOR CAMERA CALIBRATION

The recovery of three-dimensional information from a set of two-dimensional images requires the use of an accurate, and fast calibration technique. Although diverse techniques have been developed for single and multiple camera configurations, selection of the most appropriate task-specific technique is a non-trivial exercise. Therefore, in this paper, we present a review of calibration techniques, their respective application domains and associated boundary conditions. Boundary conditions of particular importance include, desired capture volume, available time budget, required accuracy, number of cameras and type of feature detection. Commonly used calibration tools are discussed, including their specific features and target applications. A methodology to determine the suitability of a calibration tool for a specific setup and requirements using a synthetically generated environment, is presented. Finally, a multicamera calibration tool is evaluated for its robustness in determining important calibration information under a number of envisioned camera configurations. The goal of this study is to aid the reader in the selection of the most suitable calibration techniques and tools appropriate for the task at hand.
A Fiatalok Természetismereti Klubja adatai Szőce rovarfaunájához

(Lepidoptera), negye-de bogarak (Coleoptera) (Hemiptera) erdőkhöz összes fejlődése száraz habitatokban 4%-ot sem korábbi években megjelent szakcikkekben 649 rovarfaunájára Abstract. The "Club of Young Naturalists" (FTK) has been investigating the peat-bog near Szőce, Western Hungary for 29 years; functioning as the Youth Division of the Hungarian Biological Society, summer camps have been organized near this habitat since 1988. Fundamental part of our research activities is the exploration of insect fauna. Significant results have been achieved during the past three decades, which are presented in this work. 1222 insect species were hitherto found, 72 of them are protected and further 2 ( Cordulegaster heros T HEISCHINGER and Carabus nodulosus C REUTZER ) are strictly protected according to Hungarian laws, these two species are listed in Annex IV of EU Habitats Directive as well. Further six species of the area: Ophiogomphus cecilia , Parnassius mnemosyne , Lycaena dispar , Maculinea teleius , Maculinea nausithous and Euphydryas maturna are also listed in Annex IV. More than half of the insect checklist is represented by Lepidoptera, nearly one quarter by Coleoptera, and 8% belongs to Hemiptera. One-third of the species are silvicolous, but nearly one-seventh require open habitats. Nearly 20% of the species are hygrophilous, 6% lives in, on or near water at their particular stage, while less than 4% of the species are xerophilous. We found 649 species which were not published from the area yet, including the two strictly protected taxa. List of these new species as well as that of protected taxa are presented.
Design of the Reverse Channel for Remanufacturing: Must Profit‐Maximization Harm the Environment?

A key attribute of a remanufacturing strategy is the division of labor in the reverse channel, especially whether remanufacturing is performed in‐house or outsourced. We investigate this decision for a retailer who accepts returns of a remanufacturable product. Our formulation considers the cost structures of the two strategies, uncertainty in the input quality of the collected/returned used products, consumer willingness‐to‐pay for remanufactured product, the extent to which the remanufactured product cannibalizes demand for a new product, and the power structure in the channel. For the profit‐maximizing retailer, the differentials in variable remanufacturing costs drive strategy choice, and higher fixed costs of in‐house remanufacturing favors outsourcing. The variable remanufacturing costs and the balance of power in the prospective outsourced reverse channel are the key drivers of environmental impact, as measured by the retailer's propensity to remanufacture. While profitability and environmental goals often conflict, they align under certain conditions. These include (a) the third party has less bargaining power; or (b) the fixed cost for in‐house remanufacturing is relatively high. All else equal, when remanufacturing is outsourced, the environment fares better if the third party has leadership power. We generalize to the cases when remanufacturing achieves a quality level less than “good‐as‐new" and when used items have non‐zero salvage value. Analysis of these extensions illuminates how relative power in the reverse channel drives the firms’ preferences, as well as the end customers’ consumption experience.
