description: Objective of this work is to investigate the structural change and economic dynamics of farms pursuing diversification and differentiation strategies in Italy. The analysis was performed on a panel of data built on the basis of information collected by the Italian FADN between 2003-2009. For the purpose of the analysis, we divid- ed the population of commercial Italian farms into a five-fold farm typology based on size and the extent of diversification and differentiation strategies adopted by the farms. In detail, farms are defined as differentiated when they make use of a system of quality certification, while they are defined as diversified when they take up non- farming activities (agritourism, social farms etc.). The findings show that conventional farms remain by far the largest category within the population of Italian commer- cial farms, while only 13% of the total commercial farms are classified as differenti- ated and/or diversified. Farms adopting product differentiation strategies are found to have an income growth path similar to that of conventional farms. Yet the category of diversified farms is the only one showing an upward trend with regard to income per worker in the observed years, while farms relying entirely on agricultural products appear to perform poorly in terms of labour productivity.

description: Developing fast and accurate methods to discover intermetallic compounds is relevant for alloy design. While density-functional-theory (DFT)-based methods have accelerated design of binary and ternary alloys by providing rapid access to the energy and properties of the stable intermetallics, they are not amenable for rapidly screening the vast combinatorial space of multi-principal element alloys (MPEAs). Here, a machine-learning model is presented for predicting the formation enthalpy of binary intermetallics and used to identify new ones. The model uses easily accessible elemental properties as descriptors and has a mean absolute error (MAE) of 0.025 eV/atom in predicting the formation enthalpy of stable binary intermetallics reported in the Materials Project database. The model further predicts stable intermetallics to form in 112 binary alloy systems that do not have any stable intermetallics reported in the Materials Project database. DFT calculations confirm one such stable intermetallic identified by the model, NbV2 to be on the convex hull. The model trained with binary intermetallics can also predict ternary intermetallics with similar accuracy as DFT, which suggests that it could be extended to identify compositionally complex intermetallics that may form in MPEAs.
Quasinormal modes of the charged black hole in Gauss-Bonnet gravity

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The d-dimensional string generated gravity models lead to Einstein-Maxwell equations with quadratic order correction term called the Gauss-Bonnet term. We calculate the quasinormal modes for the d-dimensional charged black hole in the framework of this model. The quasinormal spectrum essentially depends upon the Gauss-Bonnet coupling parameter $α$ which is related to the string scale, and is totally different from that for black holes derived from Einstein action. In particular, at large $α$ the quasinormal modes are proportional to $α$, while as $α$ goes to zero the qusinormal modes approach their Schwarzschild values. In contrary to Einstein theory black hole behavior, the damping rate of the charged GB black hole as a function of charge does not contain a chracteristic maximum, but instead the monotonic falling down is observed. In addition, there have been obtained an asymptotic formula for large multipole numbers.

description: We present an {\it ab initio} study of the recently discovered superconductivity of boron doped diamond within the framework of a phonon-mediated pairing mechanism. The role of the dopant, in substitutional position, is unconventional in that half of the coupling parameter $λ$ originates in strongly localized defect-related vibrational modes, yielding a very peaked Eliashberg $α^2F(ω)$ function. The electron-phonon coupling potential is found to be extremely large and T$_C$ is limited by the low value of the density of states at the Fermi level.

description: A classical problem of mechanics involves a projectile fired from a given point with a given velocity whose direction is varied. This results in a family of trajectories whose envelope defines the border of a 'safe' domain. In the simple cases of a constant force, harmonic potential and Kepler or Coulomb motion, the trajectories are conic curves whose envelope in a plane is another conic section which can be derived either by simple calculus or by geometrical considerations. The case of harmonic forces reveals a subtle property of the maximal sum of distances within an ellipse.

description: A comparison between two machine learning approaches viz., Genetic Fuzzy Methodology and Q-learning, is presented in this paper. The approaches are used to model controllers for a set of collaborative robots that need to work together to bring an object to a target position. The robots are fixed and are attached to the object through elastic cables. A major constraint considered in this problem is that the robots cannot communicate with each other. This means that at any instant, each robot has no motion or control information of the other robots and it can only pull or release its cable based only on the motion states of the object. This decentralized control problem provides a good example to test the capabilities and restrictions of these two machine learning approaches. The system is first trained using a set of training scenarios and then applied to an extensive test set to check the generalization achieved by each method.

description: Although representing less than 20% of total CAP expenditure, the Rural Development Policy (RDP) 2007-2013 is supposed to support rural areas which are facing new challenges. Currently, many EU rural areas are experiencing major trans- formations and the traditional urban-rural divide seems outdated (OECD, 2006). Going beyond dichotomous definitions and approaches, the paper applies at EU NUTS 3 level a new composite and comprehensive measure of rurality and periph- erality (the PeripheRurality Indicator, PRI): the higher this index, the more rural and peripheral a given region is. Within a Principal Component Analysis (PCA) approach, this indicator takes into account both conventional socio-economic indicators and the relevant geographical characteristics of the region. On the basis of this analysis, the paper also puts forward a clusterisation of NUTS 3 regions across Europe and assesses the correlation between the RDP expenditure intensity, the PRI and the different regional clusters. This analysis is aimed at assessing the coherence of RDP fund allocation with the real characteristics of EU rural space.

description: This paper presents an integrated model for the economic and environmental assessment of the use of natural resources when new activities (i.e. biomass crops for energy production) are introduced into the farm production plan. The methodology is based on the integration of positive mathematical programming (PMP) with the AquaCrop model developed by FAO. PMP represents farmer decision processes and evaluates how farms react to the biomass-sorghum activity option at different price levels. AquaCrop evaluates the relationship between water needs and biomass production and assesses the effect of the land allocation on water requirements at regional level. The integration of these two models assists global policy evaluation at regional level as it makes it possible to identify the economic threshold for biomass crops, the change in land allocation and total water requirement. The model can help policy makers to evaluate the impacts of variations in crop profitability and market innovations on farm profitability, land use and water consumption and the sustainability of the market scenario.

description: The pseudogap phenomena induced by the SC fluctuation are investigated in details. We perform a calculation beyond the 1-loop approximation. The SC fluctuation is microscopically derived on the basis of the repulsive Hubbard model. The vertex corrections are collected in the infinite order with use of the quasi-static approximation. The single-particle excitations, NMR 1/T_{1}T, spin susceptibility and superconducting transition temperature are discussed. The important role of the vertex correction is pointed out for the single particle spectral function. On the other hand, the validity of the 1-loop order theory is confirmed for other quantities. We shed light on the essential nature of SC fluctuation leading to the pseudogap from the comparison with spin and charge fluctuations.

description: We express the zeta function associated to the Laplacian operator on $S^1_r\times M$ in terms of the zeta function associated to the Laplacian on $M$, where $M$ is a compact connected Riemannian manifold. This gives formulas for the partition function of the associated physical model at low and high temperature for any compact domain $M$. Furthermore, we provide an exact formula for the zeta function at any value of $r$ when $M$ is a $D$-dimensional box or a $D$-dimensional torus; this allows a rigorous calculation of the zeta invariants and the analysis of the main thermodynamic functions associated to the physical models at finite temperature.

Assisted detection of duplicate bug reports
Creators: name: Hiew, Lyndon
Publisher: name: University of British Columbia
Year: 2010

description: Duplicate bug reports, reports which describe problems or enhancements for which there is already a report in a bug repository, consume time of bug triagers and software developers that might better be spent working on reports that describe unique requests. For many open source projects, the number of duplicate reports represents a significant percentage of the repository, numbering in the thousands of reports for many projects. In this thesis, we introduce an approach to suggest potential duplicate bug reports to a bug triager who is processing a new report. We tested our approach on four popular open source projects, achieving the best precision and recall rates of 29% and 50% respectively on reports from the popular Firefox open source project. We report on a user study in which we investigated whether our approach can help novice bug triagers process reports from the Firefox repository. Despite the relatively low precision and recall rates of our approach, we found that its use does increase the duplicate detection accuracy of novice bug triagers, while significantly reducing the number of searches they perform and slightly reducing the time they spend on each report.
title: Overcoming blinking artifacts in nanocluster detection using two-color single-molecule microscopy

Subjects: subject: superresolution microscopy

description: Observations using single-molecule localization microscopy have led to the belief that the majority of tested membrane proteins are organized in clusters at sizes below the diffraction limit. These nanoclusters are thought to play an important role in cellular signaling. However, concerns about the existence of nanoclusters have been fueled by the notion that virtually all fluorescent probes show complex blinking behavior including long-lived dark states. This results in localization clusters due to the repeated observation of single molecules. Existing post-processing approaches commonly struggle to reliably distinguish real molecular clustering from such blinking artifacts. In this thesis, a novel analytical method is presented that uses information from two-color STORM experiments for reliably detecting molecular clustering while overcoming the erroneous detection of clustering due to fluorophore blinking. Targeting the same protein species with differently labeled antibodies allows for the calculation of distance distributions between localizations from both color channels. Molecular clusters exhibit a characteristic bias towards shorter distances. Applying toroidal shifts to the data breaks possible correlations between the two color channels, thus providing surrogates for realizations of the null hypothesis of randomly distributed molecules. This allows for statistical signiffcance tests without the necessity of additional calibration. This work evaluates the limits of the method with Monte Carlo simulations and experiments on clustered and randomly distributed membrane proteins.

description: We demonstrate mid-infrared (MIR) frequency combs at 10 GHz repetition rate via intra-pulse difference-frequency generation (DFG) in quasi-phase-matched nonlinear media. Few-cycle pump pulses ($\mathbf{\lesssim}$15 fs, 100 pJ) from a near-infrared (NIR) electro-optic frequency comb are provided via nonlinear soliton-like compression in photonic-chip silicon-nitride waveguides. Subsequent intra-pulse DFG in periodically-poled lithium niobate waveguides yields MIR frequency combs in the 3.1--4.1 $μ$m region, while orientation-patterned gallium phosphide provides coverage across 7--11 $μ$m. Cascaded second-order nonlinearities simultaneously provide access to the carrier-envelope-offset frequency of the pump source via in-line f-2f nonlinear interferometry. The high-repetition rate MIR frequency combs introduced here can be used for condensed phase spectroscopy and applications such as laser heterodyne radiometry.

Hierbei wird das Prinzip der Neighborhood Unit angewendet und demnach eine Siedlung entworfen. Der gewählte Bauplatz befindet sich in der Stadt Salzburg und umfasst ungefähr 900.000 m². Auf diesem Grundstück wird die Struktur der Verkehrsflächen, die Anordnung der Wohnbauten, Nahversorger sowie die Grünflächen und Freiflächen in adaptierter Form der Neighborhood Unit auf neue Art und Weise entworfen. Der Entwurf dieser Wohnbauten wird durch eigens entworfene Modulgrößen entwickelt. So können in nur kurzer Zeit verschiedene Typen von Wohnungen und auch verschiedene Wohnbauten entworfen werden. Zusätzlich dazu kann ein lebenswerter Raum zur Verfügung gestellt und maximale Erholungsflächen geschaffen werden.
description: Broadly speaking, this diploma thesis focuses on the establishment of a neighborhood unit in Salzburg. More specifically, the principle of the Neighborhood Unit is used in order to plan a housing complex. The chosen building ground is situated in the city of Salzburg and comprises about 900.000 m². There, the structure of the traffic area, the arrangement of the housing complexes, the shops (local supply) as well as the open spaces are constructed in a similar, yet altered form of the Neighborhood Unit. The concept of the housing complexes is based on specifically designed modules. In that way, it is possible to create various types of apartments and thus different complexes in a short period of time. Additionally, an area worth living can be provided and room for recreation is built.
LiveRAC : live reorderable accordion drawing

description: LiveRAC is a scalable focus+context approach for monitoring computer systems and networking data that provides user-directed data reordering and details-on-demand. LiveRAC maps alarm and metric data from network devices including servers, routers and switches into a visual metaphor called accordion drawing. In accordion drawing, users interact with the display as though it were a rubber sheet tacked down at the borders. Regions of the display can be stretched and compressed, but the fixed borders ensure the visibility of the entire information space. Compressed regions of the display aggregate the underlying data. We implement guaranteed visibility, a mechanism for ensuring the visibility of important features such as critical alarms. LiveRAC extends existing accordion drawing techniques in two ways: it can add, remove and reorder objects to the data set in logarithmic time, and provides an infrastructure for semantic zoom, a visualization technique where an optimal data representation is selected based on the screen space available to a data cell. Using a client-server approach we allow the user to query the underlying data in a context-rich, visually salient metaphor while maintaining interactive frame rates.
Novel tools for plastid engineering in higher plants

Publisher: name: No Publisher Supplied
Year: 2020

description: Plastid genome engineering holds great promise in many biotechnological applications, including production of vaccines and antibodies, conferring insect tolerance by expressing dsRNAs, implanting novel metabolic pathways and improving photosynthetic efficiency and so on. However, the plastid transformation technology is not yet available in most crop plants. I was part of the group that developed a system for plastid transformation in Arabidopsis thaliana, a Brassicaceae species, that is potentially applicable to the important oilseed crop canola (Brassica napus) and vegetable brassicas such as broccoli, cauliflower and cabbage (Brassica oleracea). Efficient plastid transformation is enabled by eliminating a duplicate fatty acid biosynthetic pathway in chloroplasts. High level expression of recombinant proteins is desirable, but it may cripple the plant growth. To achieve on demand expression of plastid transgenes, I was involved in a project that exploited the use of an engineered PPR (pentatricopeptide) RNA-binding protein for post-transcriptional regulation of chloroplast genes. One application is ethanol-inducible expression of chloroplast proteins by activating mRNA translation when the protein is needed. Thus, the transplastomic plants can be grown full size in the absence of the inducer and expression is turned on during the protein production phase. The second application is tuber-specific expression of plastid genes where plastid gene expression is normally very law. When the engineered PPR variant is expressed from a tuber-specific patatin promoter, a 60-fold increase over 0.02%, the maximum protein yield achieved to date, has been obtained in the potato tuber. Plastids represent an appealing target for synthetic biology applications, where predictable protein output is of paramount importance. I designed synthetic operons from which reporter gene expression could be obtained in tobacco chloroplasts over a large dynamic range by post-transcriptional regulation, using the right combination of RNA binding proteins, RNA-binding protein binding sites and RNA processing elements.

Dark Matter Prediction from Canonical Quantum Gravity with Frame Fixing

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We show how, in canonical quantum cosmology, the frame fixing induces a new energy density contribution having features compatible with the (actual) cold dark matter component of the Universe. First we quantize the closed Friedmann-Robertson-Walker (FRW) model in a sinchronous reference and determine the spectrum of the super-Hamiltonian in the presence of ultra-relativistic matter and a perfect gas contribution. Then we include in this model small inhomogeneous (spherical) perturbations in the spirit of the Lemaitre-Tolman cosmology. The main issue of our analysis consists in outlining that, in the classical limit, the non-zero eigenvalue of the super-Hamiltonian can make account for the present value of the dark matter critical parameter. Furthermore we obtain a direct correlation between the inhomogeneities in our dark matter candidate and those one appearing in the ultra-relativistic matter.

description: The mechanical properties of collagen fibrils in tendon tissue have been a focus of scientific interest as their function to transfer loads from muscle to bone are a critical aspect of locomotion. However, efforts to heal and regenerate tendon are still challenged by the limited knowledge on its natural development within the body. Especially the effects of intrafibrillar interactions on the mechanical properties of individual collagen fibrils is not yet fully understood. The functional characterisation of individual collagen fibrils during embryonic development can provide new perspectives on collagen structure, mechanics and maturation. Understanding the assembly and mechanics of individual early collagen fibrils has major implications for tissue morphogenesis and repair. The goal of this thesis was to investigate changes in mechanical properties of individual tendon collagen fibrils during embryonic chick development. In this context enzymatic cross-linking is one point of focus as the chemical modification in similar chicks is known as it has been studied before. Nanomechanical assessment of individual collagen fibrils was conducted in phosphate buffered saline through cantilever-based nanoindentation via atomic force microscopy which proved to be a promising tool for research on tissue biomechanics. With this technique collagen fibrils of less than 30 nm during embryonic development in chicks from stage HH37 to HH41 were mechanically characterised. The recorded data was analysed with the Oliver-Pharr method to calculate the indentation moduli of individual collagen fibrils at the mentioned developmental stages. The experiments showed that the indentation moduli of single collagen fibrils during embryonic chick development increase non-linearly from 1.63 MPa to 2.74 MPa from development stage HH38 to HH41, respectively (p < 0.05). This indicates an accumulation of cross-links during continued embryonic development. Also, small but significant changes in fibril diameter after HH39 could be determined (p < 0.05). Furthermore, the effect of enzymatic cross-linking on the indentation modulus of collagen fibrils harvested from chick embryos that had been treated in ovo with β-aminopropionitrile to inhibit lysyl-oxidase-mediated cross-linking were investigated. The treated collagen fibrils showed a significantly lower indentation modulus than fibrils treated with saline in a comparison group (p < 0.05). This suggests that lysyl-oxidase-mediated cross-linking is partly, if not completely, responsible for the non-linearly increasing indentation modulus of collagen fibrils during embryonic development and therefore contributes to changes in mechanical properties of tendon during development.

description: During the last years, Canary banana suppliers have made the decision of withdraw a significant part of their exportable supply from the Iberian Peninsula market. In this paper, an analytical tool is provided to evaluate the marginal effects of these decisions on revenues and profit. The key element is the estimation of a model to explain prices as a function of exports. The optimal export levels obtained from this procedure should be cautiously taken due to limitations on statistical information, but should be seen as a guide to the decision making process.

description: Below band gap formation of solvated electrons in neutral water clusters using pump-probe photoelectron imaging is compared with recent data for liquid water and with above band gap excitation studies in the liquid and clusters. Similar relaxation times in the order of 200 fs and 1-2 ps are retrieved for below and above band gap excitation, in both clusters and liquid. The relaxation times independence from the generation process indicates that these times are dominated by the solvent response, which is significantly slower than the different solvated electron formation processes. The analysis of the temporal evolution of the vertical electron binding energy and the electron binding energy at half maximum suggests a dependence of the solvation time on the binding energy.

description: We consider four-dimensional N=1 supersymmetric gauge theories in a supergravity background. We use generalized Konishi anomaly equations and R-symmetry anomaly to compute the exact perturbative and non-perturbative gravitational F-terms. We study two types of theories: The first model breaks supersymmetry dynamically, and the second is based on a $G_2$ gauge group. The results are compared with the corresponding vector models. We discuss the diagrammatic expansion of the $G_2$ theory.

description: Broadband dual-comb spectroscopy (DCS) based on portable mode-locked fiber frequency combs is a powerful tool for in situ, calibration free, multi-species spectroscopy. While the acquisition of a single spectrum with mode-locked DCS typically takes microseconds to milliseconds, the applications of these spectrometers have generally been limited to systems and processes with time changes on the order of seconds or minutes due to the need to average many spectra to reach a high signal-to-noise ratio (SNR). Here, we demonstrate high-speed, continuous, fiber mode-locked laser DCS with down to 11 $μ$s time resolution. We achieve this by filtering the comb spectra using portable Fabry-Perot cavities to generate filtered combs with 1 GHz tooth spacing. The 1 GHz spacing increases the DCS acquisition speed and SNR for a given optical bandwidth while retaining a sufficient spacing to resolve absorption features over a wide range of conditions. We measure spectra of methane inside a rapid compression machine throughout the 16 ms compression cycle with 133 cm$^{-1}$ bandwidth (4000 comb teeth) and 1.4 ms time resolution by spectrally filtering one of the combs. By filtering both combs, we measured a single-shot, 25 cm$^{-1}$ (750 comb teeth) spectrum of CO around 6330 cm$^{-1}$ in 11 $μ$s. The technique enables simultaneously high-speed and high-resolution DCS measurements, and can be applied anywhere within the octave-spanning spectrum of robust and portable fiber mode-locked frequency combs.
Scalar field theory on $κ$-Minkowski space-time and Doubly Special Relativity

description: In this paper we recall the construction of scalar field action on $κ$-Minkowski space-time and investigate its properties. In particular we show how the co-product of $κ$-Poincaré algebra of symmetries arises from the analysis of the symmetries of the action, expressed in terms of Fourier transformed fields. We also derive the action on commuting space-time, equivalent to the original one. Adding the self-interaction $Φ^4$ term we investigate the modified conservation laws. We show that the local interactions on $κ$-Minkowski space-time give rise to 6 inequivalent ways in which energy and momentum can be conserved at four-point vertex. We discuss the relevance of these results for Doubly Special Relativity.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Using Schwinger-Dyson equations and Ward identities in N=1 supersymmetric electrodynamics, regularized by higher derivatives, we find, that it is possible to calculate some contributions to the two-point Green function of the gauge field and to the beta-function exactly to all orders of the perturbation theory. The results are applied for the investigation of the anomaly puzzle in the considered theory.

subject: 46E35, 53C25

description: In this paper we are focusing on functional inequalities on compact simple edge spaces. More precisely we address the question whether the classical functional inequalities (Sobolev, Poincaré) hold in this setting, and as a by-product of our methods we obtain an optimality result concerning the $B-$constant of the Sobolev inequality.

subject: beef.

description: In this paper, tariff equivalent of NTMs are estimated considering the beef trade (frozen and fresh beef, bone and boneless) between Brazil and the EU, for the period from 2000 to 2010. The literature review points out a considerable number of requirements that affect beef trade. A model is estimated, assuming homogeneity and heterogeneity of goods, and following the methodology proposed by Yue, Beghin and Jensen (2005). In general, high values for the tariff equivalents are observed, i.e., the European domestic prices and the world prices actually differ, which could indicate that the European beef market has been protected by NTMs.
O Moderno Arcaísmo Nacional: investimento estrangeiro direto e expropriação territorial no agronegócio canavieiro

subject: monoculture of sugarcane
subject: foreign direct investment
subject: territorial reconfiguration.

description: This paper aims to understand territorial reconfigurations triggered in the Brazilian countryside from the early 2000s due to the expansion of monocultures of sugarcane for the agrofuels’ production. For this, it uses a theoretical approach that considers the existence of environmental and territorial conflicts associated with the operative logic of capitalist exploitation, and seeks to elucidate the presence of hegemonic speeches aimed to become invisible distinct and non-dominant modes of use and ownership of natural resources. The construction of the argument will use concepts considered obsolete by the academic doxa, such as imperialism, dependency, and primitive accumulation. Moreover, inspired by the contributions of Latin American intellectuals agglutinated in the so-called paradigm modernity-coloniality, the article will propose that the asymmetric ownership of natural resources has been part of a condition of coloniality in the appropriation of nature.

description: Using available quantum Monte Carlo predictions for a strictly 2D electron gas, we have estimated the spin susceptibility of electrons in actual devices taking into account the effect of the finite transverse thickness and finding a very good agreement with experiments. A weak disorder, as found in very clean devices and/or at densities not too low, just brings about a minor enhancement of the susceptibility.

Spectral singularities and tunable slab lasers with 2D material coating

description: We investigate linear and nonlinear spectral singularities in the transverse electric and transverse magnetic modes of a slab laser consisting of an active planar slab sandwiched between a pair of Graphene or Weyl semimetal thin sheets. The requirement of the presence of linear spectral singularities gives the laser threshold condition while the existence of nonlinear spectral singularities due to an induced weak Kerr nonlinearity allows for computing the laser output intensity in the vicinity of the threshold. The presence of the Graphene and Weyl semimetal sheets introduces additional physical parameters that we can use to tune the output intensity of the laser. We provide a comprehensive study of this phenomenon and report peculiarities of lasing in the TM modes of the slab with Weyl semimetal coatings. In particular, we reveal the existence of a critical angle such that no lasing seems possible for TM modes of the slab with smaller emission angle. Our results suggest that for TM modes with emission angle slightly exceeding the critical angle, the laser output intensity becomes highly sensitive to the physical parameters of the coating.
