Molecular Imprinting Techniques Used for the Preparation of Biosensors
Authors: Ertürk Gizem , Mattiasson Bo
Published: February 2017

Molecular imprinting is the technology of creating artificial recognition sites in polymeric matrices which are complementary to the template in their size, shape and spatial arrangement of the functional groups. Molecularly imprinted polymers (MIPs) and their incorporation with various transducer platforms are among the most promising approaches for detection of several analytes. There are a variety of molecular imprinting techniques used for the preparation of biomimetic sensors including bulk imprinting, surface imprinting (soft lithography, template immobilization, grafting, emulsion polymerization) and epitope imprinting. This chapter presents an overview of all of these techniques with examples from particular publications.
G-Channel Restoration for RWB CFA with Double-Exposed W Channel
Authors: Park Chulhee , Song Ki , Kang Moon
Published: February 2017

In this paper, we propose a green (G)-channel restoration for a red–white–blue (RWB) color filter array (CFA) image sensor using the dual sampling technique. By using white (W) pixels instead of G pixels, the RWB CFA provides high-sensitivity imaging and an improved signal-to-noise ratio compared to the Bayer CFA. However, owing to this high sensitivity, the W pixel values become rapidly over-saturated before the red–blue (RB) pixel values reach the appropriate levels. Because the missing G color information included in the W channel cannot be restored with a saturated W, multiple captures with dual sampling are necessary to solve this early W-pixel saturation problem. Each W pixel has a different exposure time when compared to those of the R and B pixels, because the W pixels are double-exposed. Therefore, a RWB-to-RGB color conversion method is required in order to restore the G color information, using a double-exposed W channel. The proposed G-channel restoration algorithm restores G color information from the W channel by considering the energy difference caused by the different exposure times. Using the proposed method, the RGB full-color image can be obtained while maintaining the high-sensitivity characteristic of the W pixels.
Calibration of Laser Beam Direction for Inner Diameter Measuring Device
Authors: Yang Tongyu , Wang Zhong , Wu Zhengang , Li Xingqiang , Wang Lei , Liu Changjie
Published: February 2017

The laser triangulation method is one of the most advanced methods for large inner diameter measurement. Our research group proposed a kind of inner diameter measuring device that is principally composed of three laser displacement sensors known to be fixed in the same plane measurement position. It is necessary to calibrate the direction of the laser beams that are emitted by laser displacement sensors because they do not meet the theoretical model accurately. For the purpose of calibrating the direction of laser beams, a calibration method and mathematical model were proposed. The inner diameter measuring device is equipped with the spindle of the machine tool. The laser beams rotate and translate in the plane and constitute the rotary rays which are driven to scan the inner surface of the ring gauge. The direction calibration of the laser beams can be completed by the sensors’ distance information and corresponding data processing method. The corresponding error sources are analyzed and the validity of the method is verified. After the calibration, the measurement error of the inner diameter measuring device reduced from ± 25 μ m to ± 15 μ m and the relative error was not more than 0.011%.
Detectability Analysis of Road Vehicles in Radarsat-2 Fully Polarimetric SAR Images for Traffic Monitoring
Authors: Zhang Bo , Wang Chao , Zhang Hong , Wu Fan , Tang Yi-Xian
Published: February 2017

By acquiring information over a wide area regardless of weather conditions and solar illumination, space-borne Synthetic Aperture Radar (SAR) has the potential to be a promising application for traffic monitoring. However, the backscatter character of a vehicle in a SAR image is unstable and varies with image parameters, such as aspect and incidence angle. To investigate vehicle detectability in SAR images for traffic monitoring applications, images of four common types of vehicles in China were acquired using the fully polarimetric (FP) SAR of Radarsat-2 in our experiments. Methods for measuring a vehicle’s aspect angle and backscatter intensity are introduced. The experimental FP SAR images are used to analyze the detectability, which is affected by factors such as vehicle size, vehicle shape, and aspect angle. Moreover, a new metric to improve vehicle detectability in FP SAR images is proposed and compared with the well-known intensity metric. The experimental results show that shape is a crucial factor in affecting the backscatter intensity of vehicles, which also oscillates with varying aspect angle. If the size of a vehicle is smaller than the SAR image resolution, using the intensity metric would result in low detectability. However, it could be improved in an FP SAR image by using the proposed metric. Compared with the intensity metric, the overall detectability is improved from 72% to 90% in our experiments. Therefore, this study indicates that FP SAR images have the ability to detect stationary vehicles on the road and are meaningful for traffic monitoring.
A 3D Human-Machine Integrated Design and Analysis Framework for Squat Exercises with a Smith Machine
Authors: Lee Haerin , Jung Moonki , Lee Ki-Kwang , Lee Sang
Published: February 2017

In this paper, we propose a three-dimensional design and evaluation framework and process based on a probabilistic-based motion synthesis algorithm and biomechanical analysis system for the design of the Smith machine and squat training programs. Moreover, we implemented a prototype system to validate the proposed framework. The framework consists of an integrated human–machine–environment model as well as a squat motion synthesis system and biomechanical analysis system. In the design and evaluation process, we created an integrated model in which interactions between a human body and machine or the ground are modeled as joints with constraints at contact points. Next, we generated Smith squat motion using the motion synthesis program based on a Gaussian process regression algorithm with a set of given values for independent variables. Then, using the biomechanical analysis system, we simulated joint moments and muscle activities from the input of the integrated model and squat motion. We validated the model and algorithm through physical experiments measuring the electromyography (EMG) signals, ground forces, and squat motions as well as through a biomechanical simulation of muscle forces. The proposed approach enables the incorporation of biomechanics in the design process and reduces the need for physical experiments and prototypes in the development of training programs and new Smith machines.
Rhabdomyosarcoma of the Paranasal Sinuses Initially Diagnosed as Acute Sinusitis
Authors: Dilger Amanda , Schneider Alexander , Cramer John , Shintani Smith Stephanie
Published: February 2017

Rhabdomyosarcoma (RMS) is an uncommon soft tissue malignancy that is typically found in the pediatric population. Here we describe a rare case of widely metastatic alveolar RMS of the right paranasal sinuses in an adult woman who presented with several months of unilateral sinus symptoms that was initially misdiagnosed as acute sinusitis. A middle-aged female presented with two months of right sinus pressure and unilateral epistaxis. She had previously been diagnosed with acute sinusitis and was treated with antibiotics without improvement. Nasal endoscopy demonstrated a fungating right nasal cavity mass. On computed tomography scan (CT), she was found to have metastatic disease in the mediastinum, lungs, bones, pancreas, and right ovary. Pathology of the nasal cavity mass was consistent with alveolar RMS. The patient initially responded well to chemotherapy, but subsequently developed brain and leptomeningeal metastases. This case of sinonasal rhabdomyosarcoma is unique in the extent of metastatic disease at the time of diagnosis and the initial misdiagnosis despite concerning unilateral symptoms and imaging. This thus highlights the importance of maintaining a high index of suspicion for malignancy in patients with unilateral sinus symptoms.
Chinese Electric Power Development Coordination Analysis on Resource, Production and Consumption: A Provincial Case Study
Authors: Zhu Jiang , Zhao Zhenyu
Published: February 2017

In line with the pressures of energy shortage and economic development, Chinese government has adopted a series of measures and policies to promote the exploitation and utilization efficiency of electric power. China is urgently reconsidering its electric power development level and coordinating between power supply and demand sides. Therefore, in this paper, Chinese industrial structure of electric power was constructed according to its production process from resource, production and consumption sides. With the constructed industrial structure, the influencing factors on each side were selected to build a measurable evaluation system. Thirty-one Chinese provinces were chosen to explore their development coordination level based on the projection pursuit model and coupling coordination model. By the projection pursuit model, improved projection directions and best projection vectors of each province were found to describe the development level of each side. The coupling coordination model was adopted to explore the provincial supply and demand relations between electric power industry side via the indexes of coupling degree, coordination degree and relative development degree. By using ArcGIS mapping analysis, the results show the changes in Chinese provincial coupling and coordination development levels from 2011 to 2014. Finally, using the evaluation results, optimal strategies were discussed for improving the coordination of Chinese electric power development from different aspects, such as technical support, project approval and supervision, and demand side management. The findings prove that projection pursuit model and coupling coordination model can evaluate the electric power development level and describe their dynamic changing coordination relations effectively.
Human T Cell Memory: A Dynamic View
Authors: Macallan Derek , Borghans José , Asquith Becca
Published: February 2017

Long-term T cell-mediated protection depends upon the formation of a pool of memory cells to protect against future pathogen challenge. In this review we argue that looking at T cell memory from a dynamic viewpoint can help in understanding how memory populations are maintained following pathogen exposure or vaccination. For example, a dynamic view resolves the apparent paradox between the relatively short lifespans of individual memory cells and very long-lived immunological memory by focussing on the persistence of clonal populations, rather than individual cells. Clonal survival is achieved by balancing proliferation, death and differentiation rates within and between identifiable phenotypic pools; such pools correspond broadly to sequential stages in the linear differentiation pathway. Each pool has its own characteristic kinetics, but only when considered as a population; single cells exhibit considerable heterogeneity. In humans, we tend to concentrate on circulating cells, but memory T cells in non-lymphoid tissues and bone marrow are increasingly recognised as critical for immune defence; their kinetics, however, remain largely unexplored. Considering vaccination from this viewpoint shifts the focus from the size of the primary response to the survival of the clone and enables identification of critical system pinch-points and opportunities to improve vaccine efficacy.
Les lames à coche du second Mésolithique : des outils dédiés au travail des plantes ?
Authors: Gassin Bernard , Marchand Grégor , Claud Émilie , Guéret Colas , Philibert Sylvie
Published: February 2017

Durant le VIIe millénaire avant J.-C., des changements importants sont constatés dans les industries lithiques d’Europe occidentale. La production lithique est centrée sur des lamelles régulières, débitées par pression ou percussion indirecte. Ces lamelles sont souvent retouchées pour former une ou plusieurs coches, façonnant parfois des bords denticulés. Nous avons étudié un échantillon de lames à coches provenant de différents sites mésolithiques du VIIe et du VIe millénaire av. J.-C. : Beg-an-Dorchenn, L’Essart, La Grange (Ouest de la France), Noyen-sur-Seine, Choisy-au-Bac (Bassin parisien), Verrebroek Aven Ackers et Oudenaarde (Belgique), Mourre de Sève (Provence), La Grande Rivoire (Alpes), Dammartin-Marpain (Jura). Cette étude préliminaire présente nos premiers résultats, quelques hypothèses fonctionnelles et une discussion sur la place des lames à coches dans les assemblages lithiques. Dans le corpus étudié, les coches sont systématiquement directes et le plus souvent obtenues par flexion. L’analyse fonctionnelle montre que les coches sont utilisées comme outils de raclage. La dissymétrie des polis observés sur la face inférieure et sur la face supérieure (face retouchée) indique que la face supérieure est systématiquement en position de face d’attaque, avec un angle d’attaque voisin de 90° : il s’agit d’un raclage en coupe négative. Cette position d’utilisation est incompatible avec un détachement d’enlèvements d’utilisation en face supérieure. Nous concluons donc que les coches résultent d’une retouche volontaire et non d’un processus d’écaillage en cours d’utilisation. Il apparaît clairement que chaque coche est une zone d’utilisation autonome, utilisée par une faible longueur de tranchant. La variabilité des traces d’usure observées suggère que différents matériaux ont été travaillés, parmi lesquels différents végétaux (bois, plantes souples siliceuses de différentes natures), et, probablement, des matières osseuses. Ainsi, ces outils emblématiques du second Mésolithique résultent d’un processus technique volontaire et correspondent à des finalités fonctionnelles spécifiques. C’est un aspect particulier du renouvellement des techniques qui marque les mutations des sociétés mésolithiques au VIIe millénaire que nos premiers résultats ont ainsi mis au jour.
Le dépôt de haches à douille de type armoricain du Hallstatt D1-D2 de Trelly (Manche) : interprétations à partir des analyses chimiques élémentaires
Authors: Aranda Berenger , Le Carlier de Veslud Cécile , Marcigny Cyril , Le Bannier Jean-Christophe
Published: February 2017

En 1998, le dépôt de Trelly (Manche) a été découvert à la suite de prospections électromagnétiques. Une rapide opération de sauvetage réalisée à la même époque a permis de constater la présence d’autres objets, la plupart remués par des labours récents. L’intérêt principal de ce petit dépôt, d’une trentaine d’objets à base cuivre, est l’association entre des haches à douille de type armoricain (types de Plurien, de Tréhou et surtout de Couville) et des bracelets typiques du Hallstatt D1-D2. Si le dépôt était bien connu grâce à la publication de quelques objets lors de l’exposition «Nos ancêtres les Gaulois » présentée à Nantes en 1999 à l’occasion du XXIIe colloque de l’AFEAF, aucune analyse n’en avait été menée. Dans le cadre d’un nouveau programme de recherche mené à l’université de Rennes 1-Beaulieu (UMR «CReAAH » ) concernant les objets à base cuivre protohistoriques et leurs compositions élémentaires, des analyses chimiques ont été réalisées sur la plupart des objets du dépôt. Les résultats obtenus montrent que quelle que soit la taille des haches les teneurs en plomb et en cuivre sont variables et souvent très fortes. Les teneurs en étain sont faibles mais assez constantes. En réalisant deux analyses par hache, on démontre que cette variabilité de composition se retrouve au sein même des objets, conduisant à dire que les différences observées entre individus ne sont pas significatives. Cependant, la dispersion des compositions au sein de l’ensemble des objets du dépôt est continue, ne montrant pas de rupture, laissant penser que ces objets ont pu être fabriqués selon un même procédé technique. La comparaison entre les différents types d’objets montre que les bracelets sont seulement légèrement enrichis en étain. Les teneurs en éléments-traces pour l’ensemble des objets sont quant à elles très similaires, montrant ainsi l’homogénéité du dépôt. Ainsi, les analyses, en plus des travaux de terrain et de l’observation de la patine des objets, confirment une similitude de composition chimique. En conclusion, si elles ne confirment pas formellement le synchronisme entre les haches à douille et les bracelets du Hallstatt moyen / final, du moins apportent-elles un argument supplémentaire dans ce sens, et surtout elles ne le contredisent pas. Pour réellement confirmer cela, il faut continuer à analyser entièrement d’autres dépôts de la même région, en prenant aussi en compte des dépôts du Bronze final III.
Avant-propos

Located on the western periphery of Bandkeramik expansion and covering a large geographical area, the Paris basin is a particularly interesting region for examining the phenomena of colonisation and interaction involved in the neolithisation process. Recent years have seen the completion of a number of research projects and doctoral theses based on the analysis of finds from major excavations undertaken in the Aisne, Yonne and Marne valleys. Following this work, the broad aim of the Société préhistorique française meeting, Paris 2011, was to produce an overview of the chronology of the Bandkeramik in the Paris basin, mainly using the evidence from decorated pottery. A sound chronology is clearly essential for understanding the stages of expansion within the region, as well as relationships with neighbouring areas and the new evidence emerging for the circulation of raw materials, finished products and probably also people. Outstanding problems remain the dating of the earliest settlement of the Paris basin, the transition from late to final Bandkeramik, and regional factors involved in the transformation of the final Bandkeramik into the Blicquy/ Villeneuve-Saint-Germain culture. Lastly, a new chronological terminology is proposed (Seine basin middle, late, and final Bandkeramik), more in line with the subdivisions used in Alsace and Lorraine.
Précisions sur l’étape finale du Rubané récent du Bassin parisien et la formation du groupe de Villeneuve Saint-Germain
Authors: Constantin Claude
Published: February 2017

Quatorze années après la parution de l’article sur l’étape finale du Rubané récent du Bassin parisien (Constantin et Ilett, 1997), de nouvelles découvertes permettent de tenter une analyse plus complète et plus précise de ses caractéristiques. Cette analyse porte essentiellement sur les données céramiques, issues de trente-quatre sites. Des éléments nouveaux non évoqués en 1997 sont observés. Il apparaît à cette étape : 1) l’utilisation du dégraissant à l’os dans quelques vases ; 2) des vases à pied ; 3) des anneaux en terre d’un type nouveau ; 4) des décors de type alsacien en triangles suspendus ; 5) et probablement déjà à quelques exemplaires, des décors en arêtes de poisson et des décors modelés en V au-dessus des anses qui seront deux caractères importants du corpus céramique du groupe de Villeneuve-Saint-Germain. Indépendamment de ces précisions, nous nous sommes efforcés de caractériser, toujours à partir des données céramiques, la nature des changements entre Rubané récent du Bassin parisien et étape finale d’une part, entre étape finale et groupe de Villeneuve-Saint-Germain d’autre part. Concernant la transition Rubané récent du Bassin parisien – étape finale, il apparaît que la totalité des éléments décoratifs caractéristiques de l’étape finale sont déjà présents à quelques exemplaires dans les étapes antérieures et que c’est leur forte et conjointe augmentation qui caractérise cette étape finale. Elle est enracinée dans les étapes antérieures. Concernant la transition étape finale – Villeneuve-Saint-Germain, on peut distinguer deux processus principaux : 1) une rupture radicale avec la thématique identitaire du Rubané récent du Bassin parisien : disparition des décors en T, des décors en chevrons, des rubans à sillons transversaux, des associations peigne-sillons ; 2) une forte augmentation des autres caractères de l’étape finale qui comme nous venons de l’indiquer préexistent déjà dans les étapes antérieures. La continuité entre Rubané récent du Bassin parisien, étape finale du Rubané récent du Bassin parisien et Villeneuve-Saint-Germain témoigne de l’enracinement du groupe de Villeneuve-Saint-Germain dans le Rubané récent du Bassin parisien. Parallèlement à cette évolution, quelques sites de la fin du Rubané Récent du Bassin Parisien semblent suivre une autre trajectoire qui se manifeste par l’extrême diminution du nombre de vases décorés, traduisant un bouleversement des repères de la population de ces villages. Un chapitre supplémentaire relève, toujours pour la céramique, les spécificités de la région Seine-Yonne pendant le Rubané et l’étape ancienne du groupe de Villeneuve-Saint-Germain.

Se basant sur des caractères d'ordre divers, caractères morphologiques et anatomiques du carpophore et du mycélium, oxydases, polarité et comportement nucléaire, il montre l'hétérogénéité de ce genre. Il propose son éclatement en trois genres : genre Leptoporus avec L. mollis, type du genre Leptoporus, genre Tyromyces avec T. chioneus et kmetii, et genre Spongiporus qui comprend de nombreuses espèces à spores allantoïdes, germant au laboratoire avec difficulté, et présentant un comportement nucléaire normal du mycélium ; T. wynnei est transféré dans le genre Heteropus. A l'occasion de ce travail, une nouvelle espèce est décrite : Spongiporus luteocaesius. Les espèces nouvellement récoltées en France sont les suivantes : Tyromyces kmetii, Spongiporus guttulatus, lowei, undosus, et Heteroporus wynnei. Tyromyces kmetii non connu d'Amérique a été récolté par l'auteur en Louisiane. Enfin des interfertilités montrent ou confirment l'identité de récoltes américaines et européennes notamment pour Spongiporus stipticus, undosus et Tyromyces spraguei.

Published: February 2017

Le Cryptococcus albidus a été recherché chez les animaux morts en captivité au Parc zoologique de Paris de 1959 à 1979. Les variétés albidus et diffluens ont été décelées en plusieurs niveaux du tube digestif ; la seconde variété est la plus commune. Les mammifères hébergent plus fréquemment cette levure que les oiseaux. La sensible augmentation du portage animal et l'abondance de C. albidus dans l'air, constatées ces dernières années, laissent supposer l'existence de nouvelles niches écologiques dans l'habitat animal.

Contribution à l'étude écologique des fleuves côtiers du Liban : 2. Cours moyen et inférieur du Nahr Ibrahim
Authors: Khalaf Gaby
Published: February 2017

Après celle du Nahr-el-Kalb (Khalaf et Lahoud, 1983), l'auteur entreprend l'étude physico-chimique et zoocénotique du Nahr Ibrahim, fleuve côtier libanais de 27 km. L'importance de cette étude découle du fait que, d'une part le cours d'eau est interrompu par trois barrages qui alimentent trois centrales électriques, ce qui pourrait modifier la qualité physico-chimique de l'eau, d'autre part une énorme carrière se dresse sur son trajet et déverse d'importantes quantités de sédiments fins qui modifient la structure biocénique du fleuve. En plus, cette étude est intéressante dans la mesure où un aménagement de la vallée du Nahr Ibrahim est en projet.

Les valeurs de la turbidité et de l'indice biotique de Verneaux et Tuffery rendent bien mieux compte des effets de la carrière que l'indice de diversité de la faune.

Incremental value of 99mTc-HYNICTOC SPECT/CT over whole-body planar scintigraphy and SPECT in patients with neuroendocrine tumours
Authors: Težak Stanko , Trogrlic Mate
Published: February 2017

Aim: The aim of this study was to evaluate the additional value of 99mTc-HYNIC-TOC SPECT/CT over planar whole-body (WB) scintigraphy and SPECT alone in the detection and accurate localisation of neuroendocrine tumour (NET) lesions. Methods: This study included 65 patients with a definitive histological diagnosis of NET prior to scintigraphy. Planar WB scintigraphy, SPECT, and SPECT/CT images were acquired at 4 h postadministration of 670 MBq 99mTc-HYNIC- TOC. Additional SPECT images at 10 min after tracer administration were also acquired. Clinical and imaging follow-up findings were considered as the reference standards (minimum follow-up period, 15 months). Patient and lesion-based analyses of the efficacies of the imaging modalities were performed. Results: While 38 patients exhibited metastasis of NETs, 27 presented no evidence of metastasis. Upon patient- based analysis, the sensitivity and specificity of SPECT/CT were found to be 88.9 and 79.3 %, respectively. The diagnostic accuracies of WB scintigraphy, 4h-SPECT, and SPECT/CT were 72.3, 73.8, and 84.6 %o, respectively. The area under curve (AUC) value for SPECT/CT (0.84) was the highest, followed by those for 4h-SPECT (0.75) and WB scintigraphy (0.74). The accuracy and AUC values of SPECT/CT were significantly better compared to those of WB scintigraphy (p < 0.001), 10 min-SPECT (p < 0.001), and 4 h-SPECT (p = 0.001). The findings of SPECT/CT led to the change in treatment plan of 11 patients (16.9 %o). Conclusion: The sensitivity and diagnostic accuracy of SPECT/CT in the evaluation of NET lesions outperforms planar WB imaging or SPECT alone.
INDUSTRY-WIDE COMPETITIVENESS ASSESSMENT THROUGH FUZZY SYNTHETIC EVALUATION: THE CASE OF CEMENT INDUSTRY
Authors: ULUBEYLI Serdar
Published: February 2017

This study aims to develop a fuzzy force assessment model (FFAM) for quantifying industry-wide competition conditions (ccs) using five-force framework. It employed fuzzy synthetic evaluation to assess ccs of forces and industry, and real case of Turkish cement industry was demonstrated. As a result, FFAM provides a comprehensive and practical device. As empirical findings, ccs in cement industry are medium-to-high, and pressure from substitutes is the most effective force, followed by intensity of competitors’ rivalry, bargaining power of buyers, bargaining power of suppliers, and threat of entrants. Consequently, this study is first to propose a structured and fuzzy five-force quantification model and to assess ccs in cement industry.
TESTING ENVIRONMENTAL KUZNETS CURVE HYPOTHESIS: THE ROLE OF ENTERPRISE’S SUSTAINABILITY AND OTHER FACTORS ON GHG IN EUROPEAN COUNTRIES
Authors: LAPINSKIENĖ Giedrė , PELECKIS Kęstutis , NEDELKO Zlatko
Published: February 2017

The paper analyses the environmental Kuznets curve relationship between greenhouse gases and chosen indicators of economic development based on the panel data of 20 countries of the EU in the period 2006–2013. Besides the typical variables, such as the share of a particular polluting industry, environmental taxes, energy taxes, research and development, the dummy variable of the crises and enterprise’s sustainability score were also included in the model. The fixed effect panel model was used as a framework for the analysis. The original contribution of this paper is that the factor referring to the enterprises’ sustainability was empirically tested in the expanded model. Higher energy taxes, research and development and the number of sustainable enterprises decrease the level of greenhouse gases. The size of agriculture, production and construction has a positive sign, which means that a higher value of the indicator is associated with a higher level of greenhouse gases. This implies that the analysed set of factors can be applied to adjust the trend in the region and might be useful for the climate change policy adjustment.
EVALUATING VENDOR MANAGED INVENTORY SYSTEMS: HOW INCENTIVES CAN BENEFIT SUPPLY CHAIN PARTNERS
Authors: BİRİM Sule , SOFYALIOGLU Cigdem
Published: February 2017

In a vendor managed inventory (VMI) system, the effects of financial incentives on the entire supply chain (SC) and on the individual firms are investigated in this study. To this end, order management, order replenishment and inventory control activities of a two-echelon SC are examined via modeling using discrete event simulation. By determining the appropriate parameters for the incentives with scenario analysis, balanced profit distribution between buyers and a supplier in VMI is established. Simulation outputs of the traditional model, VMI only and VMI with incentives models are compared based on profits with paired comparisons. In VMI with incentives, both buyers, and the supplier experience higher benefits than the traditional system. This study provides a new method which eliminates the unbalanced benefit distribution due to VMI and offers almost equal benefits to the participating firms. With financial incentives, firms are encouraged to share information with each other to work in a coordinated SC.
BLOG CONTENT MANAGEMENT IN SHAPING PRO RECREATIONAL ATTITUDES
Authors: STEPANIUK Krzysztof
Published: February 2017

Abstract The main aim of this article was to research the impact of the content of recreational blogs on the change of attitude and behaviours of their recipients, as well as creating the basis to manage the content of blogs directed to achieve particular results. The study was conducted with the use of quantitative and qualitative content analysis. The contents of 691 comments left by 4 main types of commentators were analysed. The evaluation of individual entries was performed using the assumptions of the modified AIDA model of consumer behaviour. The possibility of a positive causal link between the presented content and the appearance of the signs of its impact on the behaviour of individuals tracking the posts has been proven to a minor extent only. Merely 0.5% of commentators and individuals were not engaged in running declared changing their way of life to a pro recreational and sports-related one. Conducting analyses directly on the large, narrative story-telling content with the use of a consumer behaviour model is a novelty of this paper and rarely appears in the scientific literature.

The 2014 March 29 X1 solar flare (SOL20140329T17:48) produced bright continuum emission in the far- and near-ultraviolet (NUV) and highly asymmetric chromospheric emission lines, providing long-sought constraints on the heating mechanisms of the lower atmosphere in solar flares. We analyze the continuum and emission line data from the Interface Region Imaging Spectrograph (IRIS) of the brightest flaring magnetic footpoints in this flare. We compare the NUV spectra of the brightest pixels to new radiative-hydrodynamic predictions calculated with the RADYN code using constraints on a nonthermal electron beam inferred from the collisional thick-target modeling of hard X-ray data from Reuven Ramaty High Energy Solar Spectroscopic Imager. We show that the atmospheric response to a high beam flux density satisfactorily achieves the observed continuum brightness in the NUV. The NUV continuum emission in this flare is consistent with hydrogen (Balmer) recombination radiation that originates from low optical depth in a dense chromospheric condensation and from the stationary beam-heated layers just below the condensation. A model producing two flaring regions (a condensation and stationary layers) in the lower atmosphere is also consistent with the asymmetric Fe ii chromospheric emission line profiles observed in the impulsive phase.

We analyze new optical observations of the gravitational lens system SDSS J1515+1511. These include a 2.6-year photometric monitoring with the Liverpool Telescope (LT) in the r band, as well as a spectroscopic follow-up with the LT and the Gran Telescopio Canarias (GTC). Our r-band LT light curves cover a quiescent microlensing period of the doubly imaged quasar at

 = 2.049, which permits us to robustly estimate the time delay between the two images A and B: 211 ± 5 days (1σ confidence interval; A is leading). Unfortunately, the main lensing galaxy (G1) is so faint and close to the bright quasar that it is not feasible to accurately extract its spectrum through the GTC data. However, assuming the putative redshift

 = 0.742, the GTC and LT spectra of the distant quasar are used to discuss the macrolens magnification, and the extinction and microlensing effects in G1. The new constraints on the time delay and macrolens magnification ratio essentially do not change previous findings on the mass scale of G1 and external shear, while the redshift of the lensing mass is found to be consistent with the assumed value of

. This is clear evidence that G1 is indeed located at

 = 0.742. From the GTC data, we also obtain the redshift of two additional objects (the secondary galaxy G2 and a new absorption system) and discuss their possible roles in the lens scenario.

The origin of the three-minute oscillations of intensity and velocity observed in the chromosphere of sunspot umbrae is still unclear. We investigated the spatio-spectral properties of the 3 minute oscillations of velocity in the photosphere of a sunspot umbra as well as those in the low chromosphere using the spectral data of the Ni i
λ5436, Fe i
λ5435, and Na i D2
λ5890 lines taken by the Fast Imaging Solar Spectrograph of the 1.6 m New Solar Telescope at the Big Bear Solar Observatory. As a result, we found a local enhancement of the 3 minute oscillation power in the vicinities of a light bridge (LB) and numerous umbral dots (UDs) in the photosphere. These 3 minute oscillations occurred independently of the 5 minute oscillations. Through wavelet analysis, we determined the amplitudes and phases of the 3 minute oscillations at the formation heights of the spectral lines, and they were found to be consistent with the upwardly propagating slow magnetoacoustic waves in the photosphere with energy flux large enough to explain the chromospheric oscillations. Our results suggest that the 3 minute chromospheric oscillations in this sunspot may have been generated by magnetoconvection occurring in the LB and UDs.

We present new Chandra X-ray Observatory and Hubble Space Telescope observations of eight optically selected broad-line active galactic nucleus (AGN) candidates in nearby dwarf galaxies (z < 0.055). Including archival Chandra observations of three additional sources, our sample contains all 10 galaxies from Reines et al. (2013) with both broad Hα emission and narrow-line AGN ratios (six AGNs, four composites), as well as one low-metallicity dwarf galaxy with broad Hα and narrow-line ratios characteristic of star formation. All 11 galaxies are detected in X-rays. Nuclear X-ray luminosities range from L
0.5–7keV ≈ 5 × 1039 to 1 × 1042 ergs−1. In all cases except for the star-forming galaxy, the nuclear X-ray luminosities are significantly higher than would be expected from X-ray binaries, providing strong confirmation that AGNs and composite dwarf galaxies do indeed host actively accreting black holes (BHs). Using our estimated BH masses (which range from ∼7 × 104 to 1 × 106
M
⊙), we find inferred Eddington fractions ranging from ∼0.1% to 50%, i.e., comparable to massive broad-line quasars at higher redshift. We use the HST imaging to determine the ratio of UV to X-ray emission for these AGNs, finding that they appear to be less X-ray luminous with respect to their UV emission than more massive quasars (i.e., α
OX values an average of 0.36 lower than expected based on the relation between α
OX and 2500 Å luminosity). Finally, we discuss our results in the context of different accretion models onto nuclear BHs.

High-energy gamma-ray emission from supernova remnants (SNRs) has provided a unique perspective for studies of Galactic cosmic-ray acceleration. Tycho’s SNR is a particularly good target because it is a young, type Ia SNR that has been  well-studied over a wide range of energies and located in a relatively clean environment. Since the detection of gamma-ray emission from Tycho’s SNR by VERITAS and Fermi-LAT, there have been several theoretical models proposed to explain its broadband emission and high-energy morphology. We report on an update to the gamma-ray measurements of Tycho’s SNR with 147 hr of VERITAS and 84 months of Fermi-LAT observations, which represent about a factor of two increase in exposure over previously published data. About half of the VERITAS data benefited from a camera upgrade, which has made it possible to extend the TeV measurements toward lower energies. The TeV spectral index measured by VERITAS is consistent with previous results, but the expanded energy range softens a straight power-law fit. At energies higher than 400 GeV, the power-law index is 2.92 ± 0.42stat ± 0.20sys. It is also softer than the spectral index in the GeV energy range, 2.14 ± 0.09stat ± 0.02sys, measured in this study using Fermi-LAT data. The centroid position of the gamma-ray emission is coincident with the center of the remnant, as well as with the centroid measurement of Fermi-LAT above 1 GeV. The results are consistent with an SNR shell origin of the emission, as many models assume. The updated spectrum points to a lower maximum particle energy than has been suggested previously.

We present the detection of persistent soft X-ray radiation with

–1042 erg s–1 at the location of the extremely luminous, double-humped transient ASASSN-15lh as revealed by Chandra and Swift. We interpret this finding in the context of observations from our multiwavelength campaign, which revealed the presence of weak narrow nebular emission features from the host-galaxy nucleus and clear differences with respect to superluminous supernova optical spectra. Significant UV flux variability on short timescales detected at the time of the rebrightening disfavors the shock interaction scenario as the source of energy powering the long-lived UV emission, while deep radio limits exclude the presence of relativistic jets propagating into a low-density environment. We propose a model where the extreme luminosity and double-peaked temporal structure of ASASSN-15lh is powered by a central source of ionizing radiation that produces a sudden change in the ejecta opacity at later times. As a result, UV radiation can more easily escape, producing the second bump in the light curve. We discuss different interpretations for the intrinsic nature of the ionizing source. We conclude that, if the X-ray source is physically associated with the optical–UV transient, then ASASSN-15lh most likely represents the tidal disruption of a main-sequence star by the most massive spinning black hole detected to date. In this case, ASASSN-15lh and similar events discovered in the future would constitute the most direct probes of very massive, dormant, spinning, supermassive black holes in galaxies. Future monitoring of the X-rays may allow us to distinguish between the supernova hypothesis and the hypothesis of a tidal disruption event.
The Dynamics of Very High Alfvén Mach Number Shocks in Space Plasmas

Astrophysical shocks, such as planetary bow shocks or supernova remnant shocks, are often in the high or very-high Mach number regime, and the structure of such shocks is crucial for understanding particle acceleration and plasma heating, as well inherently interesting. Recent magnetic field observations at Saturn’s bow shock, for Alfvén Mach numbers greater than about 25, have provided evidence for periodic non-stationarity, although the details of the ion- and electron-scale processes remain unclear due to limited plasma data. High-resolution, multi-spacecraft data are available for the terrestrial bow shock, but here the very high Mach number regime is only attained on extremely rare occasions. Here we present magnetic field and particle data from three such quasi-perpendicular shock crossings observed by the four-spacecraft Cluster mission. Although both ion reflection and the shock profile are modulated at the upstream ion gyroperiod timescale, the dominant wave growth in the foot takes place at sub-proton length scales and is consistent with being driven by the ion Weibel instability. The observed large-scale behavior depends strongly on cross-scale coupling between ion and electron processes, with ion reflection never fully suppressed, and this suggests a model of the shock dynamics that is in conflict with previous models of non-stationarity. Thus, the observations offer insight into the conditions prevalent in many inaccessible astrophysical environments, and provide important constraints for acceleration processes at such shocks.
