description: A non-hypothetical open-ended choice experiment (OECE) with multi-unit value elicitation formats was conducted to elicit Italian consumer willingness-to-pay (WTP) and demand for wheat-derived products (flour, pasta and bread) that were produced by adopting ecological friendly post-harvest technique (High Heat-Treated, HHT). A sample of 270 Italian consumers were surveyed in Bologna, Catania and Palermo in June 2014. Data were analyzed using double hurdle models. Consumers’ WTP and demand schedule for HHT products were estimated. Results suggest Italian consumers are willing to pay premium prices for HHT flour and HHT pasta, while they are available to pay about the same price or less for HHT packed bread compared to conventional packed bread. Price, location, perception of green consumption and frequency of consumption significantly affect both consumers’ participation and consumption decisions. We conclude by discussing the implications of our findings for industry operators and marketers.

description: Nanomechanical systems are generally embedded in a macroscopic environment where the sources of thermal noise are difficult to pinpoint. We engineer a silicon nitride membrane optomechanical resonator such that its thermal noise is acoustically driven by a spatially well-defined remote macroscopic bath. This bath acts as an acoustic blackbody emitting and absorbing acoustic radiation through the silicon substrate. Our optomechanical system acts as a sensitive detector for the blackbody temperature and for photoacoustic imaging. We demonstrate that the nanomechanical mode temperature is governed by the blackbody temperature and not by the local material temperature of the resonator. Our work presents a route to mitigate self-heating effects in optomechanical thermometry and other quantum optomechanics experiments, as well as acoustic communication in quantum information.

description: The pyranopyrazole derivatives have many biological activities. They were synthesized via a four-component coupling of aromatic aldehyde, malononitrile, ethyl acetoacetate and hydrazine hydrate. In this study, dihydropyrano[2,3-c]pyrazoles have been synthesized in the presence of nano-Al2O3/BF3/Fe3O4 as catalyst in water/ethanol under reflux conditions. The catalyst was removed from the mixture of reaction by an external magnet and was reusable for several times without any loss of its activity. The obtained pyranopyrazoles were characterized by various methods such as FT-IR, 1HNMR and melting point. Easy purification, clean and convenient procedure are some advantages of this method.

description: Today’s agriculture and food production has been topic in public discussions and the media in the last years. Societal perceptions and imaginations of agriculture seem to be far away from reality. There is no indication of a declining gap between consumers’ expectations and their perception of animal husbandry. However, precise information about expectations and priorities of the population are unknown. Thus, the paper concentrates on society’s views and opinions. On the example of intensive pig production, the objective of the study is to analyse societal perceptions, expectations and main points of criticism. It also aims on the identification and characterisation of societal groups with almost identical attitudes. By combining exploratory focus groups with a quantitative survey, a mixed method approach is pursued. Focus groups are carried out in September 2012 in three German cities to capture a variety of opinions and concerns among the population. On the basis of findings from focus groups a quantitative survey is carried out in spring 2013 per online survey with approximately 1500 German citizens to quantify qualitative results. The surveys’ findings confirmed many of the critical views gained in the focus groups. On the basis of four extracted attitudinal factors three groups with heterogeneous opinions are differentiated with respect to modern pig production. Besides a very engaged group which is characterised by a strong criticism in general and a strong critical perception of current production systems, also a considerable group accepting modern animal husbandry was identified. The multinomial logit regression finally allows for a characterisation of the identified societal segments by sociodemographic and regional aspects. Additionally, the question of responsibility and the acceptance of consequences of several governmental actions are included in the model. It turns out that gender and agricultural knowledge of the people are significant determinants in explaining cluster membership. Interestingly, opponents more often have a good knowledge of agriculture. These findings imply that negative attitudes cannot be traced back to a missing knowledge.

description: Using the APM cluster distribution we find interesting alignment effects: (1) Cluster substructure is strongly correlated with the tendency of clusters to be aligned with their nearest neighbour and in general with the nearby clusters that belong to the same supercluster, (2) Clusters belonging in superclusters show a statistical significant tendency to be aligned with the major axis orientation of their parent supercluster. Furthermore we find that dynamically young clusters are more clustered than the overall cluster population. These are strong indications that cluster develop in a hierarchical fashion by merging along the large-scale filamentary superclusters within which they are embedded.

description: We theoretically investigate the problem of finding optimal characteristics of photon pairs, produced in the spontaneous parametric down-conversion (SPDC) process, for fiber-based quantum communication (QC) protocols. By using the accessible setup parameters, the pump pulse duration and the extended phase-matching function width, we minimize the temporal width of SPDC photons within the general scenario. This allows one to perform more effectively the temporal filtering procedure, which aims at reducing the noise acquired by the measurement devices. Moreover, we compare the obtained results with the achievable parameter values for SPDC sources based on $β$-Barium Borate (BBO) crystal. We also investigate the influence of non-zero detection timing jitter. Finally, we apply our optimization strategy to a simple quantum key distribution scheme to show that the full optimization of an SPDC source can potentially extend the maximal security distance by several tens of kilometres, which is around 30\% more as compared to previous approaches.

description: In this paper we describe the heterotic dual of the type IIB theory compactified to four dimensions on a toroidal orientifold in the presence of fluxes. The type IIB background is most easily described in terms of an M-theory compactification on a four-fold. The heterotic dual is obtained by performing a series of U-dualities. We argue that these dualities preserve supersymmetry and that the supergravity description is valid after performing them. The heterotic string is compactified on a manifold that is no longer Kahler and has torsion. These manifolds have to satisfy a number of constraints, for example, existence of an holomorphic three-form, size limits, torsional equations etc. We give an explicit form of the background and study the constraints associated to them.

In massive type IIA supergravity, we obtain supersymmetric $AdS_6$ black holes asymptotic to the Brandhuber-Oz solution. In type IIB supergravity, we obtain supersymmetric $AdS_6$ black holes asymptotic to the non-Abelian T-dual of the Brandhuber-Oz solution. For the uplifted black hole solutions, we calculate the holographic entanglement entropy. In massive type IIA supergravity, it precisely matches the Bekenstein-Hawking entropy of the black hole solutions.

description: The conventional signature for grand unified theories (GUT) is the proton decay. Recently, some models in extra dimensions or with specific discrete symmetries, which aim at solving the doublet-triplet problem, allow the color-triplet in the TeV mass region by suppressing the Yukawa couplings of the triplets to matter fermions. We study the hadronic production and detection of these TeV colored Higgs bosons as an alternative signature for GUT, which would behave like massive stable charged particles in particle detectors producing a striking signature of a charged track in the central tracking system and being ionized in the outer muon chamber. We found that the LHC is sensitive to a colored Higgs boson up to about 1.5 TeV. If the color-triplets are stable in cosmological time scale, they may constitute an interesting fraction of the dark matter.
description: We added the description of a model by Goldberger et al.-- a 5D SU(5) SUSY model in a slice of AdS space with special boundary conditions to suppress proton decay. The color-triplet also has a TeV mass

description: The 2010 Eurobarometer on life science and biotechnology reveals an overall suspicion of GM foods amongst the public: the 61% of Europeans agree that GM food makes them feel uneasy and a higher proportion, 70%, think that GM food is fundamentally unnatural. In the economics literature many studies investigate the factors that drive public resistance: ethical concerns, low public trust in regulatory institution, risk misperception, absence of perceived benefits and media bias. In particular, public attitudes and risk perception about agricultural biotechnology are proved to be influenced by press media communication. This paper aims at gaining insight into the visual communication to which Italian population is exposed about GMOs, in order to investigate if images could have contributed to shape their negative public perception. A set of 500 images collected through Google search for “GMO” in Italy are classified considering fearful attributes (i.e. alteration of color, shape or size of plants or animals, mention to death or war, presence of DNA double helix or syringe) and an index that accounts for the scary impact of these images is built. Then the relationship between the index and a set of variables that refer to the context in which images appear is estimated. Preliminary results reveal that the order of appearance of images negatively affect index, namely that the first (and most viewed) Google result pages contain the most frightful images. It suggests that Italian population is subject to overstated negative inputs about GMOs. In addition, it emerges that web contents that show positive or neutral GMO attitudes are barely accompanied with objective and balanced visual communication. Implications and future research are then discussed.

description: Automated pavement distresses detection using road images remains a challenging topic in the computer vision research community. Recent developments in deep learning has led to considerable research activity directed towards improving the efficacy of automated pavement distress identification and rating. Deep learning models require a large ground truth data set, which is often not readily available in the case of pavements. In this study, a labeled dataset approach is introduced as a first step towards a more robust, easy-to-deploy pavement condition assessment system. The technique is termed herein as the Pavement Image Dataset (PID) method. The dataset consists of images captured from two camera views of an identical pavement segment, i.e., a wide-view and a top-down view. The wide-view images were used to classify the distresses and to train the deep learning frameworks, while the top-down view images allowed calculation of distress density, which will be used in future studies aimed at automated pavement rating. For the wide view group dataset, 7,237 images were manually annotated and distresses classified into nine categories. Images were extracted using the Google Application Programming Interface (API), selecting street-view images using a python-based code developed for this project. The new dataset was evaluated using two mainstream deep learning frameworks: You Only Look Once (YOLO v2) and Faster Region Convolution Neural Network (Faster R-CNN). Accuracy scores using the F1 index were found to be 0.84 for YOLOv2 and 0.65 for the Faster R-CNN model runs; both quite acceptable considering the convenience of utilizing Google maps images.

description: We analyze the structure of the imaginary part of the two-loop Euler-Heisenberg QED effective Lagrangian for a constant self-dual background. The novel feature of the two-loop result, compared to one-loop, is that the prefactor of each exponential (instanton) term in the imaginary part has itself an asymptotic expansion. We also perform a high-precision test of Borel summation techniques applied to the weak-field expansion, and find that the Borel dispersion relations reproduce the full prefactor of the leading imaginary contribution.

Astrometric radial velocities III. Hipparcos measurements of nearby star clusters and associations

description: Radial motions of stars in nearby moving clusters are determined from accurate proper motions and trigonometric parallaxes, without any use of spectroscopy. Assuming that cluster members share the same velocity vector (apart from a random dispersion), we apply a maximum-likelihood method on astrometric data from Hipparcos to compute radial and space velocities (and their dispersions) in the Ursa Major, Hyades, Coma Berenices, Pleiades, and Praesepe clusters, and for the alpha Persei, Scorpius-Centaurus, and `HIP 98321' associations. The radial motion of the Hyades cluster is determined to within 0.47 km/s (standard error), and that of its individual stars to within 0.6 km/s. For other clusters, Hipparcos data yield astrometric radial velocities with typical accuracies of a few km/s. A comparison of these astrometric values with spectroscopic radial velocities in the literature shows a good general agreement and, in the case of the best-determined Hyades cluster, also permits searches for subtle astrophysical differences, such as evidence for enhanced convective blueshifts of F-dwarf spectra, and decreased gravitational redshifts in giants. Similar comparisons for the Scorpius OB2 complex indicate some expansion of its associations, albeit slower than expected from their ages. As a by-product from the radial-velocity solutions, kinematically improved parallaxes for individual stars are obtained, enabling Hertzsprung-Russell diagrams with unprecedented accuracy in luminosity. For the Hyades (parallax accuracy 0.3 mas), its main sequence resembles a thin line, possibly with wiggles in it.

This type of communication with stakeholders is of growing importance. Opportunities and challenges of communication through social media channels are identified with special emphasis on small and medium-sized enterprises (SMEs) in the agri-food sector. 8 expert interviews were conducted on the basis of a broad literature review. The results of the qualitative interviews are analyzed by means of a comprehensive computer aided qualitative content analysis. The study enables the reader to get insights into the current situation regarding the implementation of CSR communication through social media channels in SMEs. Opportunities and threats of the application of social media are identified. The results are compared with relevant findings from literature.

This study aims to evaluate sensitivity of and variability between readers of prostate MRI outside specialized units with radical prostatectomy (RP) specimen as the reference standard. Materials and methods: Retrospective study comprising a consecutive cohort of all 97 men who underwent MRI and subsequent RP between January 2012 and December 2014 at a private hospital in Sweden. Three readers, blinded to clinical data, reviewed all images (including 11 extra prostate MRI to reduce bias). A tumour was considered detected if the overall PI-RADS v2 score was 3–5 and there was an approximate match (same or neighbouring sector) of tumour sector according to a 24 sector system used for both MRI and whole mount sections. Results: Detection rate for the index tumour ranged from 67 to 76%, if PI-RADS 3–5 lesions were considered positive and 54–66% if only PI-RADS score 4–5 tumours were included. Detection rate for aggressive tumours (GS ≥ 4 + 3) was higher; 83.1% for PI-RADS 3–5 and 79.2% for PI-RADS 4–5. The agreement between readers showed average κ values of 0.41 for PI-RADS score 3–5 and 0.51 for PI-RADS score 4–5. Conclusions: Prostate MRI evidenced a moderate detection rate for clinically significant PC with a rather large variability between readers. Clinics outside specialized units must have knowledge of their performance of prostate MRI before considering omitting biopsies in men with negative MRI.

description: We consider Dirac monopoles embedded into SU(N) gauge theory with theta-term for $θ= 4πM $ (where $M$ is half-integer for $N = 2$ and is integer for $N>2$). Due to the theta - term those monopoles obtain the SU(N) charge and become the dyons. They belong to different irreducible representations of SU(N) (but not to all of them). The admitted representations are enumerated. Their minimal rank increases with increasing of $N$. The main result of the paper is the representation of the partition function of SU(N) model with theta-term (that contains singular gauge fields correspondent to the mentioned monopoles) as the vacuum average of the product of Wilson loops (considered along the monopole worldlines). This vacuum average should be calculated within the correspondent model without theta-term.

description: Innovation is a clear target of the Europe 2020 growth strategy. It has been widely postulated that cooperation is especially important for innovation in the food industry because it has traditionally been regarded as a “low tech” sector. This paper analyses how different forms of cooperation affect innovation activities in the EU’s food industry. In particular, the study addresses the question of how cooperation between companies and key chain agents influences innovative activity. To do so, we analysed data at the country level drawn from the Community Innovation Survey (CIS). The aggregated data allowed us to investigate national system-level processes that must be considered the outcomes of micro-level decisions and policies. A random effect linear model is formulated and estimated to analyse the panel data obtained from five CIS waves. The model indicates that cooperation with universities positively affects innovative activity and, surprisingly, that government financial support has not been an effective instrument to foster innovation by food companies.

description: Contraction Clustering (RASTER) is a single-pass algorithm for density-based clustering of 2D data. It can process arbitrary amounts of data in linear time and in constant memory, quickly identifying approximate clusters. It also exhibits good scalability in the presence of multiple CPU cores. RASTER exhibits very competitive performance compared to standard clustering algorithms, but at the cost of decreased precision. Yet, RASTER is limited to batch processing and unable to identify clusters that only exist temporarily. In contrast, S-RASTER is an adaptation of RASTER to the stream processing paradigm that is able to identify clusters in evolving data streams. This algorithm retains the main benefits of its parent algorithm, i.e. single-pass linear time cost and constant memory requirements for each discrete time step within a sliding window. The sliding window is efficiently pruned, and clustering is still performed in linear time. Like RASTER, S-RASTER trades off an often negligible amount of precision for speed. Our evaluation shows that competing algorithms are at least 50% slower. Furthermore, S-RASTER shows good qualitative results, based on standard metrics. It is very well suited to real-world scenarios where clustering does not happen continually but only periodically.

description: Poster presented at the Fall 2008 AGU meeting by Stephan Zednik (zednik@ucar.edu), Jose Garcia (jgarcia@ucar.edu), Peter Fox (pfox@cs.rpi.edu), Patrick West (pwest@ucar.edu)Abstract: 

Across geosciences, there are large data holdings being made available via the DAP protocol by means of OPeNDAP software. A lot of the underlying data are in the NetCDF format. Often, each individual dataset is a combination of hundreds of individual NetCDF files. Requesting such datasets for analysis is an expensive data fusion transaction, especially as the number and size of datasets increase. We present a set of solutions that instead request needed portions of the data fused just-in-time. The fusion includes both subsetting and aggregation operations as well as analysis and data manipulation steps. We have modified the NetCDF C library for Remote NetCDF Invocation (RNI) that is, to operate on remote dataset, over HTTP, HTTPS or GSIFTP (or any) protocols, individual NetCDF Application Programming Interface (API) calls as if they were local. This Invocation model can also be applied to OPeNDAP data streams, and local files. This mechanism resembles the well known Remote Procedure Call (RPC) yet it radically differs on the binding between local and remote remote operations. We describe our current approach, implementation and benefits obtained from this approach and indicate how it aids data fusion.

description: We use data from the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory to image the shell surrounding the pulsar B0540-69, and to measure its spectral properties. Weak emission line features, notably of Fe, Mg and Si, indicate that the shell is composed primarily of ambient material heated by the blast wave. The shell emission in the east is faint and circular in appearance, with a temperature and ionization age of approximately 5 keV and 10^10 cm^-3 s, respectively. The emission in the west is brighter and has a more complex, distorted morphology, and is fitted with significantly lower average temperatures and higher ionization ages. An image with photon energies above 2 keV shows two hard arcs of emission located diametrically opposite each other at the outer boundary of the remnant shell; the spectra from these regions could include a substantial nonthermal component.

description: Innovation has been identified as a critical asset for SMEs to survive (Hitt et al., 2001; Lee et al., 2001). However, SMEs that need to improve their innovation process often lack the essential resources to innovate when relying solely on their in-house activities (Batterink et al., 2010). A large body of literature therefore highlights the role of external partnerships, or networks (Lazzarini et al., 2001; Pittaway et al., 2004; Sawhney et al., 2006). Despite the increasing number of studies focusing on the relationship between networking and innovation, there is still considerable ambiguity and debate within literature regarding appropriate network characteristics for successful innovations (Nieto and Santamaria, 2007; Pittaway et al., 2004). Furthermore, the existing studies focus mostly on high tech companies (Edquist 2006, van Galen 2008). The objective of our study is to gain insight into the network characteristics critical for successful innovations within the agricultural sector in Flanders. The study is based on interviews and focus group discussions with farmers and network coordinators active in Flanders. In total, 109 respondents were consulted. This research is based on four innovation characteristics which seem crucial for each innovation (Kanter, 1988). For each of these innovation characteristics, we investigated how networks could contribute, via their network characteristics. The results showed that networks serves as a net for knowledge about e.g. new technologies, or changing legislation in order that farmers are faster aware of developments. When farmers have multiple contacts, they have a higher chance to discover new things. Thereby, it is important that knowledge providers are part of the network and connected with the different actors, and not only provide their information to the farmers as an external actor. Also the face-to-face communication within a network is an essential issue. Furthermore, coalition can play a crucial role for some innovations, as a lot of farmers are not able to implement their idea because for example the retailer or research institute is not supportive or interested. If the farmers set up a self-initiated coalition, it can be easier to initiate the innovative idea. Fourth, it is important that individual actors from the agricultural system revisit their actual role. Successful innovation processes often originate in situations where creativity is not limited within one unit. Based on the findings, recommendations for farmers as well as network coordinators are formulated to increase the innovation capacity.

description: We present extensive tests of the Fast Action Method (FAM) for recovering the past orbits of mass tracers in an expanding universe from their redshift-space coordinates at the present epoch. The tests focus on the reconstruction of present-day peculiar velocities using mock catalogs extracted from high resolution $N$-body simulations. The method allows for a self-consistent treatment of redshift-space distortions by direct minimization of a modified action for a cosmological gravitating system. When applied to ideal, volume limited catalogs, FAM recovers unbiased peculiar velocities with a 1-D, 1σerror of ~220 km/s, if velocities are smoothed on a scale of 5 Mpc/h. Alternatively, when no smoothing is applied, FAM predicts nearly unbiased velocities for objects residing outside the highest density regions. In this second case the 1σ$error decreases to a level of ~150 km/s. The correlation properties of the peculiar velocity fields are also correctly recovered on scales larger than 5 Mpc/h. Similar results are obtained when FAM is applied to flux limited catalogs mimicking the IRAS PSCz survey. In this case FAM reconstructs peculiar velocities with similar intrinsic random errors, while velocity-velocity correlation properties are well reproduced beyond scales of ~8 Mpc/h. We also show that FAM provides better velocity predictions than other, competing methods based on linear theory or Zel'dovich approximation. These results indicate that FAM can be successfully applied to presently available galaxy redshift surveys such as IRAS PSCz.

description: Let $\cF$ be a family of finite loops closed under subloops and factor loops. Then every loop in $\cF$ has the strong Lagrange property if and only if every simple loop in $\cF$ has the weak Lagrange property. We exhibit several such families, and indicate how the Lagrange property enters into the problem of existence of finite simple loops.
