description: The interplay between discrete vibrational and electronic degrees of freedom directly influences the chemical and physical properties of molecular systems. This coupling is typically studied through optical methods such as fluorescence, absorption, and Raman spectroscopy. Molecular electronic devices provide new opportunities for exploring vibration-electronic interactions at the single molecule level. For example, electrons injected from a scanning tunneling microscope tip into a metal can excite vibrational excitations of a molecule in the gap between tip and metal. Here we show how current directly injected into a freely suspended individual single-wall carbon nanotube can be used to excite, detect, and control a specific vibrational mode of the molecule. Electrons inelastically tunneling into the nanotube cause a non-equilibrium occupation of the radial breathing mode, leading to both stimulated emission and absorption of phonons by successive electron tunneling events. We exploit this effect to measure a phonon lifetime on the order of 10 nanoseconds, corresponding to a quality factor well over 10000 for this nanomechanical oscillator.

description: The dynamical arrest of attractive colloidal particles into out-of-equilibrium structures, known as gelation, is central to biophysics, materials science, nanotechnology, and food and cosmetic applications, but a complete understanding is lacking. In particular, for intermediate particle density and attraction, the structure formation process remains unclear. Here, we show that the gelation of short-range attractive particles is governed by a nonequilibrium percolation process. We combine experiments on critical Casimir colloidal suspensions, numerical simulations, and analytical modeling with a master kinetic equation to show that cluster sizes and correlation lengths diverge with exponents 1.6 and 0.8, respectively, consistent with percolation theory, while detailed balance in the particle attachment and detachment processes is broken. Cluster masses exhibit power-law distributions with exponents -3/2 and -5/2 before and after percolation, as predicted by solutions to the master kinetic equation. These results revealing a nonequilibrium continuous phase transition unify the structural arrest and yielding into related frameworks.

description: The availability of efficiency estimation software freely distributed via the internet and relatively easy to use recently inflated the number of corresponding applications. The resulting efficiency estimates are often used without a critical assessment with respect to the literature on theoretical consistency, flexibility and the choice of the appropriate functional form. The robustness of policy suggestions based on inferences from efficiency measures nevertheless crucially depends on theoretically well-founded estimates. This paper addresses stochastic efficiency measurement by critically reviewing the theoretical consistency of recently published technical efficiency estimates. The results confirm the need for a posteriori checking the regularity of the estimated frontier by the researcher and, if necessary, the a priori imposition of the theoretical requirements.

description: This paper integrates indicators of environmental, social and economic impact of a range of policy scenarios through the use of Multicriteria and Multiperiod Programming. The case study is irrigated agriculture in the basin of the River Guadalquivir, and the policy scenarios combined Common Agricultural Policy and Water Framework Directive implementation in the period 2001-2010. The model is applied to a representative number of farming systems that attempt to offer a satisfactory description of the productive diversity of the basin. Results indicate that there are significant differences in the impact in the three dimensions (environmental, social and economic), according to the possible evolution of policy, market and technical futures. We believe that the integration of indicators into multicriteria models is a powerful system for building policy support tools for sounder decision making in the implementation of a future normative which will affect agricultural production in Europe, and that these tools can be used to deal with new questions that face agriculture (genetically modified organisms, new CAP, etc.)

description: It is shown that when dependence on the second flow of the KP hierarchy is added, the resulting semi-stationary wave function of certain points in George Wilson's adelic Grassmannian are generating functions of the exceptional Hermite orthogonal polynomials. This surprising correspondence between different mathematical objects that were not previously known to be so closely related is interesting in its own right, but also proves useful in two ways: it leads to new algorithms for effectively computing the associated differential and difference operators and it also answers some open questions about them.

The pursuit of rigor : David Hilbert’s early philosophy of mathematics
Creators: name: Ogawa, Yoshinori
Publisher: name: University of British Columbia
Year: 2009

description: The present study attempts to provide a new approach to Hilbert's philosophy of mathematics by going back to the origin of his foundational investigation and clearly describing the Problematik within which it was framed and developed. In so doing, its main objective is to identify and highlight the general intellectual tendencies invariably and continuously motivating Hilbert's research program throughout his long career. The study consists of two parts. In the first half, special emphasis is laid upon Hilbert's axiomatic method and his accompanying view of axioms and definitions. It is argued there that Hilbert's goal with his axiomatization program is to demonstrate the objectivity of mathematical judgment and inference and to systematize and thereby to increase our understanding of mathematics. The present study attempts to support this claim by embedding Hilbert's project in the context of the late nineteenth century movement of the "rigorization" of mathematics and by understanding it as a development of the methodological standpoint represented by Dedekind. On the interpretation presented here, then, Hilbert's foundational investigation was not, as is often claimed, motivated by the philosophical concerns for the absolute certainty and a prioricity of our mathematical knowledge and, indeed, it combated against the intrusion of such concerns by relegating framework-independent elements through the "new" methodological turn in the conception of axiomatics. In the second half of the study, this non-standard reading is extended to Hilbert's consistency program, and his first attempt of a direct consistency proof and Poincare's criticism of it are considered in this light. Hilbert's answer to Poincare came with the remarkable idea of proof-theory and the formulation of finitary mathematics as the framework for proof - theoretic considerations. But, seen from a philosophical viewpoint, this methodological move meant the re-introduction of the notions of truth and existence taken in the absolute sense and, as a result, a motivation for adopting (mathematical) instrumentalism as the philosophy of Hilbert's program arose. But even after this "epistemological" turn, the earlier view continued to be operative in Hilbert's thought, and this, I shall argue, explains the "tension" found in the philosophy behind Hilbert's program.

description: This paper reports the results of a European agricultural outlook exercise that updates former studies in three ways, i.e. in terms of timeframes, spatial coverage and policy context. This updated European agricultural outlook constitutes a key component of the forthcoming 'State of the Environment and Outlook report' of the European Environment Agency (EEA). Both activity variables and environmental indicators are reported for a baseline projection and alternative scenarios. The main findings include the following: European harvested land is expected to continue to be primarily used to fodder activities and production of cereals (80% of total area); yields increase is projected to be the main source of production growth in Europe over the next 20 years; environmental pressures are expected to significantly increase in the New Member States, as a result primarily of considerable increase in fertilizers use.

At these energies, the quasielastic scattering can be well described by a single-channel potential model. Exploiting this fact, we point out that systems which involve spherical nuclei require the diffuseness parameter of around 0.60 fm in order to fit the experimental data, while systems with a deformed target between 0.8 fm and 1.1 fm.

description: The aim of this paper is to analyse the long term movements and, particularly, the seasonal pattern of Tenerife (Canary Islands) tomato exports throughout the last two decades. In order to observe more clearly the exporter's decisions, weekly data has been used. The instabilities in the long term behaviour of the series and the specific nature of the seasonal pattern should be taken into account in order to capture the performance of exports accurately. Thus, this analysis is carried out inside the frame delimited by the structural approach to time series and the usefulness of evolving splines as a tool capable of modelling seasonal variations in which either the period or the magnitude of the fluctuations do not remain the same over time is shown.

Huang's solution of the mathematical problem of constructing modular tensor categories from the representation theory of vertex operator algebras is very briefly discussed, along with background material. The hypotheses of the theorems entering into the solution are very general, natural and purely algebraic, and have been verified in a wide range of familiar examples, while the theory itself is heavily analytic and geometric as well as algebraic.

description: Our motivation is lying on the questions "How does a food scare and information of a food scare influence the buying decision of one single agent and the changes in the aggregate demand?" and "How can we evaluate effective risk communication strategies?". Since we investigate a society of consumers which do have their own decision functions, we can observe how new information could influence the behaviour of each consumer and more interesting the aggregate changes in the demand by creating a population of agents. This multi agent simulation can be used to investigate how different information releases and decision functions influence the aggregate demand. The agents get information from the networks in which they are present. Then this information will be processed, the trust regarding the food item under investigation will be updated and taken into account for the own decision. Our intention is to measure how different risk communication strategies influence the aggregate demand. For this purpose we use a multi agent method in order to follow a bottom up approach where each agent acts individually. The interaction between the agents leads to an emergence of an aggregate demand that comes from the bottom up. Each agent follows its internal updating and decision algorithms so that on the aggregate level the demand changes according to the outcomes of the interaction and its related updating processes. After the communication phases the aggregation of the outcomes of each agent shows the result of the information strategy that was selected. In this way we can test and investigate different risk communication strategies and evaluate these information policies, i.e. the benefits of a risk communication strategy can be evaluated with this multi agent approach.

description: Joist to header connectors are widely available in different shapes and sizes. One of the most common types resembles dovetail connections, where two parts slide into each other to enable load transfer (Figure 1a). Usually, aluminium is used for the connectors. One scope of the here presented project was to replace the aluminium with densified veneer wood (DVW). The connectors are mostly fastened with self-tapping and fully threaded screws, which are often inclined by 45° to the connector plane. In such connections with inclined screws, the load parallel to the shear plane is mainly transferred by axial screw loading, see Bejtka & Blass (2002). Due to equilib-rium conditions, a compressive force results perpendicular to the shear plane. This compressive force leads to frictional resistance, which depends on the size of the compressive force and the coefficient of friction µ. For connections with inclined screws, this additional load-carrying capacity can be taken into account by default, although the screws are loaded in tension. This is the difference to connections un-der combined lateral and tensile load, where the load increase due to friction, i.e. the rope effect, cannot be applied. Another scope of the project was to utilize the frictional resistance, which depends on the size of the compressive force and the co-efficient of friction (COF). Therefore, two possibilities can be examined: (i) increasing the compressive force by designing the connection to reach the tensile capacity of the screws and (ii) increasing the COF by treating the surface adequately. The latter was done in this study.

description: As the field of Music Information Retrieval grows, it is important to take into consideration the multi-modality of music and how aspects of musical engagement such as movement and gesture might be taken into account. Bodily movement is universally associated with music and reflective of important individual features related to music preference such as personality, mood, and empathy. Future multimodal MIR systems may benefit from taking these aspects into account. The current study addresses this by identifying individual differences, specifically Big Five personality traits, and scores on the Empathy and Systemizing Quotients (EQ/SQ) from participants' free dance movements. Our model successfully explored the unseen space for personality as well as EQ, SQ, which has not previously been accomplished for the latter. R2 scores for personality, EQ, and SQ were 76.3%, 77.1%, and 86.7% respectively. As a follow-up, we investigated which bodily joints were most important in defining these traits. We discuss how further research may explore how the mapping of these traits to movement patterns can be used to build a more personalized, multi-modal recommendation system, as well as potential therapeutic applications.

description: Cosmological black holes (CBH), i.e. black holes with masses larger than $10^{14} solar masses, have been proposed as possible progenitors of galaxy voids (Stornaiolo 2002). The presence of a CBH in the central regions of a void should induce significant gravitational lensing effects and in this paper we discuss such gravitational signatures using simulated data. These signatures may be summarized as follows: i) a blind spot in the projected position of the CBH where no objects can be detected; ii) an excess of faint secondary images; iii) an excess of double images having a characteristic angular separation. All these signatures are shown to be detectable in future deep surveys.

description: This paper presents a consistent description of the formation and the subsequent evolution of gaseous planets, with special attention to short-period, low-mass hot-Neptune planets characteristic of $μ$ Ara-like systems. We show that core accretion including migration and disk evolution and subsequent evolution taking into account irradiation and evaporation provide a viable formation mechanism for this type of strongly irradiated light planets. At an orbital distance $a \simeq$ 0.1 AU, this revised core accretion model leads to the formation of planets with total masses ranging from $\sim$ 14 $\mearth$ (0.044 $\mjup$) to $\sim$ 400 $\mearth$ (1.25 $\mjup$). The newly born planets have a dense core of $\sim$ 6 $\mearth$, independent of the total mass, and heavy element enrichments in the envelope, $M_{\rm Z,env}/M_{\rm env} $, varying from 10% to 80% from the largest to the smallest planets. We examine the dependence of the evolution of the born planet on the evaporation rate due to the incident XUV stellar flux. In order to reach a $μ$ Ara-like mass ($\sim$ 14 $\mearth$) after $\sim $ 1 Gyr, the initial planet mass must range from 166 $\mearth$ ($\sim$ 0.52 $\mjup$) to about 20 $\mearth$, for evaporation rates varying by 2 orders of magnitude, corresponding to 90% to 20% mass loss during evolution. The presence of a core and heavy elements in the envelope affects appreciably the structure and the evolution of the planet and yields $\sim 8%-9%$ difference in radius compared to coreless objects of solar composition for Saturn-mass planets. These combinations of evaporation rates and internal compositions translate into different detection probabilities, and thus different statistical distributions for hot-Neptunes and hot-Jupiters.

description: In this paper, the demand for animal welfare attributes when buying pork fillet is investigated among Swedish respondents. More specifically, the coefficients of an indirect utility function and willingness to pay for animal welfare attributes are estimated. The utility function is estimated using a multinomial logit and a random parameter logit model. A realistic scenario when modeling consumer choices is to allow for heterogeneity in preferences. The random parameter logit model departs from the well known IIA property and allows for a more flexible taste distribution across individuals. The need for assuming randomness of some parameters are evaluated by using a specification testing procedure with artificial variables developed by McFadden and Train (2000). From this study it can be concluded that the preferences for some of the animal welfare attributes are heterogenous across the respondents. There exists both negative and positive wtp for animal welfare attributes. Further, the study reports on the distribution of individual wtp.

description: Near-infrared images have been used to search for bright globular clusters near the center of the elliptical galaxy Maffei 1. The number of objects in various radial intervals from the center of Maffei 1 are compared with the number density of sources in two control fields, and we find an excess of 31 +/- 11 objects with K between 16.6 and 18.0 in an annulus between 20 and 90 arcsec from the galaxy center. At radii in excess of 90 arcsec the ability to find clusters is frustrated by statistical noise in the foreground star population. It is demonstrated that the globular clusters located within 90 arcsec of the center of Maffei 1 span a range of near-infrared colors that are at least as great as that which is seen among M31 clusters; some of the clusters appear to have colors that are consistent with them being very young. The specific globular cluster frequency within 90 arcsec of the center of Maffei 1 is S_N = 1.3 +/- 0.6 if the distance modulus is 28.1 +/- 0.2 and A_V = 4.7 +/- 0.2. The specific cluster frequency of Maffei 1 is thus similar to that of other nearby field elliptical galaxies.

description: A survey of 600 consumers was conducted in Nairobi to determine attitudes and willingness to pay (WTP) for GM maize meal. WTP was estimated using the double-bounded logit model. Overall, 38% are aware of GM crops. Most consumers believe in the technology's positive impacts, but are concerned about environmental and health risks. Majority (68%) would buy GM maize meal at the price of their favourite maize meal brand. The mean WTP for GM maize meal is KShs 58 for a 2kg packet, a premium of 13.7 % over mean average price of favourite brands. WTP is influenced more by subjective than socioeconomic characteristics.

description: In the paper we present an architecture of a keyword spotting (KWS) system that is based on modern neural networks, yields good performance on various types of speech data and can run very fast. We focus mainly on the last aspect and propose optimizations for all the steps required in a KWS design: signal processing and likelihood computation, Viterbi decoding, spot candidate detection and confidence calculation. We present time and memory efficient modelling by bidirectional feedforward sequential memory networks (an alternative to recurrent nets) either by standard triphones or so called quasi-monophones, and an entirely forward decoding of speech frames (with minimal need for look back). Several variants of the proposed scheme are evaluated on 3 large Czech datasets (broadcast, internet and telephone, 17 hours in total) and their performance is compared by Detection Error Tradeoff (DET) diagrams and real-time (RT) factors. We demonstrate that the complete system can run in a single pass with a RT factor close to 0.001 if all optimizations (including a GPU for likelihood computation) are applied.

description: Food processors are interested not only to increase the safety of their products but also to reduce losses associated with foodborne illness problems. Irradiating food products provides one means of addressing the foodborne illness issue by significantly reducing the presence of foodborne bacteria and diseases. The objective of the study is to develop an empirical model to estimate the likelihood of consumers purchasing irradiated food products and their willingness to pay for irradiated poultry and pork products within a two-step decision-making process. The decision-making framework assumes that consumers decide first whether or not to buy irradiated foods. If so, the consumer then decides specifically how much that they are willing to pay. Thus, a probit model on whether or not to buy irradiated products is estimated jointly with an OLS equation for the price premiums that consumers are willing to pay for irradiated meats. The study is based on the data collected from telephone interviews with a randomly selected sample of 303 adults, 18 years of age and older in Georgia, USA. The study identifies important socio-demographic variables and other qualitative and attitudinal factors that may affect consumer acceptance and willingness to pay for irradiated poultry products. The results suggest that educating consumer about irradiation would be beneficial to the food industry. The producers should develop strategies targeting the market segment that is receptive to using irradiation in the production process to enhance food safety and reduce incidents of foodborne illness.
Bardeen-Petterson effect and the disk structure of the Seyfert galaxy NGC 1068

description: VLBA high spatial resolution observations of the disk structure of the active galactic nucleus NGC 1068 has recently revealed that the kinematics and geometry of this AGN is well characterized by an outer disk of H2O maser emission having a compact milliarcsecond (parsec) scale structure, which is encircling a thin rotating inner disk surrounding a ~10^7 M$_\sun$ compact mass, likely a black hole. A curious feature in this source is the occurrence of a misalignment between the inner and outer parts of the disk, with the galaxy's radio jet being orthogonal to the inner disk. We interpret this peculiar configuration as due to the Bardeen-Petterson effect, a general relativistic effect that warps an initially inclined (to the black hole equator) viscous disk, and drives the angular momentum vector of its inner part into alignment with the rotating black hole spin. We estimate the time-scale for both angular momenta to get aligned as a function the spin parameter of the Kerr black hole. We also reproduce the shape of the parsec and kiloparsec scale jets, assuming a model in which the jet is precessing with a period and aperture angle that decrease exponentially with time, as expected from the Bardeen-Petterson effect.

description: Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with this purpose has not been found in the literature. Therefore, this paper aims (1) to present AHP as a useful methodology to effectively assess and compare the multifunctional performances of agricultural systems, and (2) to apply AHP in the comparison, on the basis of experts' knowledge, of multiple functions -economic, technical, sociocultural and environmental- of conventional, organic and integrated olive producing systems in a region of Spain, and test the hypothetical superiority of the alternative systems with respect to the conventional one in the medium/long term and the average conditions of the region. Results confirm this global superiority thus providing a scientific base to endorse institutional and social support regarding the promotion and implementation of these alternative farming techniques. However, environmental issues are the more conflictive among experts and require a more in depth research in the future to clarify many of them.

description: One of the major limitations of adaptive optics (AO) corrected image post-processing is the lack of knowledge on the system point spread function (PSF). The PSF is not always available as a direct imaging on isolated point like objects such as stars. Its prediction using AO telemetry also suffers from serious limitations and requires complex and yet not fully operational algorithms. A very attractive solution consists in a direct PSF estimation using the scientific images themselves thanks to blind or myopic post-processing approaches. We demonstrate that such approaches suffer from severe limitations when a joint restitution of object and PSF parameters is performed. As an alternative we propose here a marginalized PSF identification that overcomes this limitation. Then the PSF is used for image post-processing. Here we focus on deconvolution, a post-processing technique to restore the object, given the image and the PSF. We show that the PSF estimated by marginalisation provides good quality deconvolution. The full process of marginalized PSF estimation and deconvolution constitutes a successful blind deconvolution technique. It is tested on simulated data to measure its performance. It is also tested on experimental adaptive optics images of the asteroid 4-Vesta by VLT/SPHERE/Zimpol to demonstrate application to on-sky data.
