Published: July 2016

SummaryIt is always computing intensive and time consuming to extract polygons from massive classified images. Although parallel computing can improve the efficiency of geographical data processing, the performance of the conversion suffers from the trade‐off between data decomposition and result stitching. In this paper, we present an adaptable parallel strategy that accelerates the conversion process on a multi‐core cluster. The strategy improves the method of data decomposition and optimizes task scheduling. In our strategy, an adaptable decomposition method is used to partition raster data according to the data complexity of the raster dataset and computing capability of the computing nodes. Moreover, the hierarchical task scheduling optimizes task allocation and load balance among computing nodes for the procedure of parallel conversion and stitching. We implemented parallel algorithms based on a boundary linking algorithm using the adaptable parallel strategy and compared the performance with the performances of conventional parallel strategies. The results show that the processing time of experimental raster data was reduced from 1362.36 to 165.78 s and that a desirable speedup with the maximal value of 8.23 was achieved.

A survey of techniques for designing and managing CPU register file
Authors: Mittal Sparsh 
Published: July 2016

SummaryProcessor register file (RF) is an important microarchitectural component used for storing operands and results of instructions. The design and operation of RF have crucial impact on the performance, energy efficiency, and reliability of the processor, and hence, several techniques have been recently proposed to manage RF in modern processors. In this paper, we present a survey of techniques for architecting and managing CPU register file. We classify the techniques across several parameters to underscore their similarities and differences. We hope that this paper will provide insights to researchers into working of RF and inspire even more efforts towards optimization of RF in next‐generation computing systems.

Published: July 2016

AbstractMoS2 and WS2 have been prepared on a conductive graphene support by thermal reduction of tetrathiotungstate/tetrathiomolybdate and graphite oxide. Whereas the catalytic properties towards hydrogen evolution are strongly influenced by the Magnéli phases formed as a byproduct during the synthesis, the catalytic activity towards oxygen reduction of these composite materials is not affected by this phenomenon and these materials exhibit high catalytic activity towards this industrially important reaction.
Boron as an Electron‐Pair Donor for B⋅⋅⋅Cl Halogen Bonds
Authors: Alkorta Ibon , Elguero José , Del Bene Janet E. 
Published: July 2016

AbstractMP2/aug′‐cc‐pVTZ calculations were performed to investigate boron as an electron‐pair donor in halogen‐bonded complexes (CO)2(HB):ClX and (N2)2(HB):ClX, for X=F, Cl, OH, NC, CN, CCH, CH3, and H. Equilibrium halogen‐bonded complexes with boron as the electron‐pair donor are found on all of the potential surfaces, except for (CO)2(HB):ClCH3and (N2)2(HB):ClF. The majority of these complexes are stabilized by traditional halogen bonds, except for (CO)2(HB):ClF, (CO)2(HB):ClCl, (N2)2(HB):ClCl, and (N2)2(HB):ClOH, which are stabilized by chlorine‐shared halogen bonds. These complexes have increased binding energies and shorter B−Cl distances. Charge transfer stabilizes all complexes and occurs from the B lone pair to the σ* Cl−A orbital of ClX, in which A is the atom of X directly bonded to Cl. A second reduced charge‐transfer interaction occurs in (CO)2(HB):ClX complexes from the Cl lone pair to the π* C≡O orbitals. Equation‐of‐motion coupled cluster singles and doubles (EOM‐CCSD) spin–spin coupling constants,1xJ(B‐Cl), across the halogen bonds are also indicative of the changing nature of this bond.1xJ(B‐Cl) values for both series of complexes are positive at long distances, increase as the distance decreases, and then decrease as the halogen bonds change from traditional to chlorine‐shared bonds, and begin to approach the values for the covalent bonds in the corresponding ions [(CO)2(HB)−Cl]+and [(N2)2(HB)−Cl]+. Changes in11B chemical shieldings upon complexation correlate with changes in the charges on B.
Topcoat Transmission Measurement and Sensitivity Evaluation for Detection of Thermally Grown Oxide Layer of Thermal Barrier Coating
Authors: FUKUCHI TETSUO , ETO SHUZO , OKADA MITSUTOSHI , FUJII TOMOHARU 
Published: July 2016

SUMMARYThe thermally grown oxide (TGO) layer, which forms below the topcoat of thermal barrier coating (TBC), is an important factor that causes topcoat delamination, and its detection is important for health monitoring of TBC. Photoluminescence detects the emission from Cr3+ in the TGO layer upon laser excitation, and is an effective, nondestructive method to detect the TGO layer. In this method, the laser light and Cr3+ photoluminescence must transmit through the topcoat, so the topcoat transmittance is a limiting factor of the measurement sensitivity. In this report, the topcoat transmittance was measured by comparing the photoluminescence intensities from the TGO layer in the presence and absence of the topcoat. The round‐trip transmittance of the topcoat of thickness 300 μm was 1.26%, corresponding to an attenuation coefficient of 7.3 mm‐1. The sensitivity of the luminescence measurement was evaluated by placing ND filters of known attenuation in front of the TGO layer, to simulate the attenuation for different topcoat thickness. The results showed that luminescence measurement is possible for a maximum topcoat thickness of about 700 μm. A method to adjust the photoluminescence intensity for different topcoat thickness is presented.
Dopaminergic receptor blockade changes a functional connectivity network centred on the amygdala

Published: July 2016

AbstractResting‐state connectivity has become an increasingly important measure in characterizing the functional integrity of brain circuits in neuro‐psychiatric conditions. One approach that has recently gained prominence in this regard—and which we use in this study—is to investigate how resting‐state connectivity depends on the integrity of certain neuromodulator systems. Here, we use a pharmacological challenge in combination with functional magnetic resonance imaging to investigate the impact of dopaminergic receptor blockade on whole brain functional connectivity in twenty healthy human subjects. Administration of the D2‐receptor antagonist haloperidol led to a profound change in functional integration in network nodes linked to the amygdala. Compared to placebo and baseline measurements, network‐based statistics and pairwise connectivity analyses revealed reduced connectivity and decreased link strength between the amygdala and the bilateral posterior cingulate cortex and other cortical areas. This was complemented by less extensive but very circumscribed enhanced connectivity between the amygdala and the right putamen during D2‐receptor blockade. It will be interesting to investigate whether these pharmacologically induced shifts in resting‐state connectivity will similarly be evident in clinical conditions that involve a dysfunction of the dopaminergic system. Our findings might also aid in interpreting alterations in more complex states, such as those seen psychiatric conditions and their treatment.

Isogeometric analysis with trimming technique for quadruple arch‐cut ridged circle waveguide
Authors: Li Peng , Liu Jun , Lin Gao , Lu Shan , Zhang Pengchong 
Published: July 2016

AbstractThe conventional non‐uniform rational B‐spline (NURBS)‐based isogeometric analysis (IGA) preserves the exact description of geometrical shapes and significantly improves the computational accuracy, but suffers from the topological limitations of a single intact NURBS patch in the parameter space, which renders IGA to be applied in complex topology like the ridged structure inconvenient. In this present work, trimming technique which is the isogeometric approach for handling two‐dimensional topologically complicated geometry with a single patch is employed to demonstrate how this issue can be resolved, and further extended to analyze the quadruple arch‐cut ridged circular waveguide. The main benefit of the proposed approach is that only one patch is sufficient to represent the complex two‐dimensional topology such as circular or any degrees of polygonal shapes. Because the finite element constituents of the trimmed elements are calculated and mapped into underlying global control variables by remodeling the trimmed elements as a single patch, various properties of conventional IGA are maintained. Numerical example illustrates the flexibility for describing complicated two‐dimensional domain, and high computational accuracy and efficiency of present method with much less degree of freedom compared to commercial finite‐element software package. Effects of arch‐cut ridge dimensions on the cut‐off wave numbers of modes are investigated in details. Copyright © 2016 John Wiley & Sons, Ltd.
The Workplace Intergenerational Climate Scale (WICS): A self‐report instrument measuring ageism in the workplace
Authors: King Scott P. , Bryant Fred B. 
Published: July 2016

SummaryThe Workplace Intergenerational Climate Scale (WICS) is designed to measure employees' attitudes and perceptions about workers of different ages in the workplace. In Study 1, an initial 18‐item measure was developed, reflecting five subscales: Intergenerational Contact, Workplace Intergenerational Retention, Positive Intergenerational Affect, Workplace Generational Inclusiveness, and Lack of Generational Stereotypes. Scores on the five WICS subscales were linked to workplace mentoring, opinions about older workers, and job satisfaction. In Study 2, the WICS items and subscales were further refined, and subscale relationships with similar constructs were explored via structural equation modeling. In Study 3, a more occupationally diverse sample was used to support criterion, incremental, discriminant, and external validity. Evidence supports the use of the WICS as a valid and reliable multidimensional measure of an organization's intergenerational climate. Copyright © 2016 John Wiley & Sons, Ltd.
A 9600‐year record of water table depth, vegetation and fire inferred from a raised peat bog, Prince Edward Island, Canadian Maritimes

Published: July 2016

ABSTRACTA 582‐cm‐long peat core was collected from Baltic Bog, an ombrotrophic peatland in north‐eastern Prince Edward Island, Canada. The core was studied for testate amoebae, plant macrofossils, macrocharcoal, peat humification and organic matter content. The results show that Baltic Bog first developed ∼9600 cal a BP as a minerotrophic peatland (fen) dominated by Cyperaceae. At 8200 cal a BP, the fen transitioned into a peat bog dominated by Sphagnum. Between 8200 and 4000 cal a BP, water table depth (WTD) was generally low and the bog surface supported trees such as Picea mariana. From 4000 to 1700 cal a BP, WTD rose and the bog became more open. The macrocharcoal results show that the period ∼2000–1000 cal a BP was characterized by several fire events that may have occurred on the bog surface at the core site. The results presented in this paper correspond closely with previous fossil pollen research done at Baltic Bog and suggest that regional climate change was a key factor in controlling long‐term WTD variability and vegetation change at the site.

AbstractBACKGROUNDThifluzamide, a succinate dehydrogenase inhibitor (SDHI) fungicide, is a promising fungicide for controlling wheat sharp eyespot (WSE). WSE is caused by Rhizoctonia cerealis. Information on the resistance mechanism of this pathogen to thifluzamide remains unavailable.RESULTSWe used selective reculturing and UV mutagenesis to generate thifluzamide‐resistant mutants. Thifluzamide‐resistant mutants were only generated through UV mutagenesis. Sequence analysis of succinate dehydrogenase (Sdh) genes revealed that two mutants had no mutation in RCSdhB, RCSdhC and RCSdhD, and the other 18 mutants all had at least one mutation in RCSdhB, RCSdhC or RCSdhD, either in a homozygous or heterozygous state. The majority of mutants included either RCSdhD‐H116Y or RCSdhC‐H139Y. They showed slight resistance to boscalid, bixafen and penflufen. Only one mutant possessed RCSdhB‐H246Y, and it showed medium resistance to boscalid and penflufen and a slight resistance to bixafen. All the thifluzamide mutants were sensitive to flutolanil. Compared with their parental isolates, these mutants present no or minor fitness penalties.CONCLUSIONHomozygous and heterozygous point mutations in the succinate dehydrogenase subunits b, c and d of R. cerealis may be involved in thifluzamide resistance. © 2016 Society of Chemical Industry

Multiwall carbon nanotubes (MWCNTs) have been synthesized by aerosol‐assisted catalytic chemical vapor deposition method from a 2% ferrocene solution in toluene at temperatures of 720 and 800 °C. After an oxidation by a HNO3/H2SO4 mixture, MWCNTs were dispersed in water and deposited in form of buckypapers with a thickness of ∼150 μm. The obtained materials were used as working electrodes of supercapacitors without adding of binder. The electrode from MWCNTs synthesized at lower temperature showed the larger capacitance in 1 M H2SO4 and 6 M KOH electrolytes, especially at low scan rates. An increase of double‐layer capacitance was due to larger specific surface and microporosity of the material; a gain in pseudocapacitance was attributed to larger quantity of oxygenated groups developed on the defective surface of nanotubes. The electrode showed a good cyclic performance during a repetitive charge/discharge test.A larger specific capacitance of MWCNTs synthesized at 720 °C is related with etching of nanotube tips and higher oxygenation of nanotube surface as the result of binder‐free buckypaper electrode preparation.
Dynamic Stress Concentrations Due to Scattering of Elastic SV Waves from a Coated Nanoinclusion with Considerations in the Interfacial Region
Authors: Ghanei Mohammadi A. R. , Hosseini Tehrani P. 
Published: July 2016

AbstractThe problem of plane elastic shear waves (SV waves) scattering from a circular nanoinclusion surrounded by an inhomogeneous interphase embedded in an elastic matrix is investigated analytically in this paper. An approach is introduced to account for the simultaneous effects of a graded interphase and surface/interface energy based on Gurtin-Murdoch's model of surface elasticity. Using the wave function expansion method, the Navier equation is solved for all three phases (nanofiber-interphase- matrix). Presenting the results in dimensionless manner, Dynamic Stress Concentration Factors (DSCF) for the present problem are obtained and the effects of several parameters on the results are studied in detail. It is understood that taking the effects of both surface/interface and interphase inhomogeneity into account leads to a significant influence on the DSCF results and consequently on the overall dynamic behavior of the nanocomposites.

Published: July 2016

ObjectiveThe product of the G72 gene is an activator of d-amino acid oxidase and has been suggested to play a role in the pathogenesis of schizophrenia. Increased G72 protein levels may be associated with disturbed glutamatergic transmission and increased reactive oxygen species. Only one pilot study by Lin et al. has investigated the potential role of serum G72 protein levels as a biomarker for schizophrenia. In this study, we aimed to compare serum G72 protein levels between patients with schizophrenia and healthy controls, and to retest the results of the previous pilot study.Materials and methodsIn total, 107 patients with a diagnosis of schizophrenia according to the inclusion and exclusion criteria and 60 age–sex-matched healthy controls were included in the study. The groups were compared regarding serum G72 protein levels.ResultsThe mean serum G72 protein values were 495.90±152.03 pg/ml in the schizophrenia group and 346.10±102.08 pg/ml in the healthy control group. The mean serum G72 protein level was significantly increased in the schizophrenia group compared with the healthy control group (t=−3.89, p<0.001). A receiver operating characteristics analysis was performed to compare the schizophrenia and healthy control groups. It was determined that the cut-off value was 141.51 pg/ml with a sensitivity of 0.991 and a specificity of 0.821.ConclusionWe suggest that serum G72 protein levels may represent a candidate biomarker for schizophrenia and have confirmed the results of the previous preliminary study. Additional studies with larger sample sizes and the inclusion of first episode schizophrenia patients are required to clarify the reliability and validity of serum G72 protein levels as a biomarker for schizophrenia.
Neonatal imitation in context: Sensorimotor development in the perinatal period
Authors: Keven Nazim , Akins Kathleen A. 
Published: July 2016

AbstractMore than 35 years ago, Meltzoff and Moore (1977) published their famous article, “Imitation of facial and manual gestures by human neonates.” Their central conclusion, that neonates can imitate, was and continues to be controversial. Here, we focus on an often-neglected aspect of this debate, namely, neonatal spontaneous behaviors themselves. We present a case study of a paradigmatic orofacial “gesture,” namely tongue protrusion and retraction (TP/R). Against the background of new research on mammalian aerodigestive development, we ask: How does the human aerodigestive system develop, and what role does TP/R play in the neonate's emerging system of aerodigestion? We show that mammalian aerodigestion develops in two phases: (1) from the onset of isolated orofacial movementsin uteroto the postnatal mastery of suckling at 4 months after birth; and (2) thereafter, from preparation to the mastery of mastication and deglutition of solid foods. Like other orofacial stereotypies, TP/R emerges in the first phase and vanishes prior to the second. Based upon recent advances in activity-driven early neural development, we suggest a sequence of three developmental events in which TP/R might participate: the acquisition of tongue control, the integration of the central pattern generator (CPG) for TP/R with other aerodigestive CPGs, and the formation of connections within the cortical maps of S1 and M1. If correct, orofacial stereotypies are crucial to the maturation of aerodigestion in the neonatal period but also unlikely to co-occur with imitative behavior.
Le risque de contiguite dans l'assurance incendie des batiments
Authors: Johansen Paul 
Published: July 2016

Le calcul de la prime de l'assurance Incendie des bâtiments se trouve compliqué par le fait qu'il doit tenir compte, non seulement du bâtiment assuré, mais également des immeubles voisins.Si deux bâtiments sont suffisamment éloignés, le risque qu'un incendie se propage de l'un à l'autre est minime, mais le risque de contiguïté, et par conséquent d'incendie total, est d'autant plus grand que leur distance est plus faible.La mesure dans laquelle le risque de contiguïté doit être retenu pour la tarification est un des problèmes les plus importants que l'Actuaire a à résoudre en assurance Incendie.Pour qu'un incendie puisse s'étendre à d'autres bâtiments, le feu doit embrasser d'abord les éléments extérieurs du bâtiment assuré, c'est-à-dire les murs, la cheminée, la toiture ou les constructions en bois attenantes. Nous appellerons de tels incendies: incendies extérieurs par opposition à incendies intérieurs qui n'embrassent que le contenu du bâtiment et les aménagements intérieurs.Par risque propre d'un bâtiment nous entendons l'indemnité moyenne annuelle de sinistre, sous la condition que ce bâtiment ne soit pas exposé au risque de contiguïté d'autres immeubles.Le risque propre se divise en une fraction qui concerne les incendies intérieurs et une autre fraction concernant les incendies extérieurs,
Le deuxième terme Re peut être exprimé par le produit de la probabilité d'un incendie extérieur et de l'indemnité moyenne de cet incendie, soit
Les éléments de ce risque propre peuvent être observés pour différents groupes de risques, c'est-à-dire chaque groupe comprenant des bâtiments d'un même genre, par exemple en ce qui concerne leur construction, leur dimension ou leur destination.
Experience rating and credibility
Authors: Braakman T. C. 
Published: July 2016

I hope that you will allow me first of all to congratulate Dr. Buhlmann on the excellent lecture he has given us and I am sure that you can all agree with me that after his general survey on experience rating and credibility, there is no need at all for me to go into the general aspects of the subject. Therefore I can start immediately to report on the contributions delivered, and I am very happy to state that, though the number of papers is rather small, namely six, their contents are qualitatively as high as has become usual at our ASTIN-Colloquia.As regards the number of contributions I just mentioned, I like to draw your attention to the fact that because the present subject was on the programme of our last colloquium in Luzern too, in some cases we had to decide whether a contribution should be considered as relevant to subject I, or as a report on further work done on subjects from previous meetings. If perhaps in some cases our choice is not in accordance with the intention of the contributor I would like to apologize for that in advance. Moreover I wish to remind you that on Friday after the summaries of the discussions, Mr. Jansen will report on those papers submitted, which were not regarded as contributions to subject 1 or 2.I would like to deal first with the papers of a more theoretical nature, afterwards going on to the contributions on special applications. Among the papers of general interest I ask your attention for the paper of Franckx entitled “Le comportement de l'assureur”. I consider this contribution as a very important attempt to compare the method of credibility theory, where as you know credibility is used as a function of the volume, with a method in which decisions are made in advance on the amount of certain levels of significance, in this way fixing what Franckx calls “le comportement a priori”.
