description: More recently, we have proposed a set of noncommutative space that describes the quantum gravity at the Planck scale [J. Phys. A: Math. Theor. 53, 115303 (2020)]. The interesting significant result we found is that, the generalized uncertainty principle induces a maximal measurable length of quantum gravity. This measurement revealed strong quantum gravitational effects at this scale and predicted a detection of gravity particles with low energies. In the present paper, to make evidence this prediction, we study in this space, the dynamics of a particle with position-dependent mass (PDM) trapped in an infinite square well. We show that, by increasing the quantum gravitational effect, the PDM of the particle increases and induces deformations of the quantum energy levels. These deformations are more pronounced as one increases the quantum levels allowing, the particle to jump from one state to another with low energies and with high probability densities.

description: We report the results of a search for the flavor-changing neutral current process b --> d gamma using a sample of 275 million B meson pairs accumulated by the Belle detector at KEKB. We find no significant signal for the exclusive decays B- --> rho- gamma, B0B --> rho0 gamma, or B0B --> omega gamma. Assuming an isospin relation between the three modes, we set an upper limit for the combined branching fraction Br(B --> (rho,omega) gamma) < 1.4 x 10-6 at the 90% confidence level. This limit can be used to constrain the ratio of CKM matrix elements |Vtd/Vts|.

This paper gives a negative answer to that question. Moreover, we prove that for a locally compact groupoid $G$ with non-singleton orbits and having open target projection, if we assume that the continuity of every morphism $F$ on the neighborhood of the base in $G$ implies the continuity of $F$ everywhere, then the groupoid $G$ must be locally transitive.

Year: 2003
Subjects: Agricultural and Food Policy

description: The paper gives a range of sustainable agricultural policy recommendations, based on the results of the previous CEESA research phases. We begin by a brief presentation of the Romanian case study dealing with the environmental awareness of farmers, measured by means of agri-environmental indicators and discrete choice modelling. Then, we present the policy instruments dealing with non-point source pollution from agriculture, focusing on those applied in the European Union, that are most likely to be used in accession countries. Here we briefly introduce the Romanian environmental institutional and legislative framework, emphasising the existent water policy instruments. We end up by proposing sustainable agricultural policies that, based on the insights of our case study, we consider to be most appropriate for the case of Romania.

Economic issues concerning the mobility of scientific inventions and implications for firm strategy
Creators: name: Agrawal, Ajay K.
Publisher: name: University of British Columbia
Year: 2009

description: It is well recognized that there are imperfections in the market for knowledge transfer due to the nature of ideas and inventions. This is consistent with market failures commonly discussed in the economics of information literature. Some of the impediments to efficiency axe examined here in three essays—one empirical, one theoretical, and one case study—all of which share the theme of scientific knowledge movement. The first essay is empirical and measures the systematic effects of direct interaction and geographic distance between university and firm scientists on the economic performance of imported inventions. This study concludes that, with respect to licensing royalties, scientific interaction has an elasticity of approximately 3 at the mean, which is highly robust, and that distance does not have a significant effect after controlling for interaction. This suggests imperfections in the market for know-how that are sensitive to distance. The second essay is a case study of an invention from the area of robotics and control systems and augments the empirical work presented in the previous essay by illustrating specific reasons why interaction was important for the commercialization of one particular early stage invention. The third essay develops a game theoretic model involving the strategic manipulation of incentives by an incumbent to create an 'intellectual property commons' for the purpose of preventing the commercial development of a disruptive technology that would otherwise threaten existing industry margins. The strategy of spoiling incentives to commercialize public sector scientific inventions by eliminating exclusive intellectual property rights—the strategy of the commons—is motivated by a fear of cannibalization and supported by a credible threat. It is shown that the degree of cannibalization to which the new technology exposes the old market is responsible for this market failure.

description: In this paper, a preliminary correspondence between the thermodynamic curvature and the isoperimetric theorem is established from a $4$-dimensional ultraspinning black hole. We find that the thermodynamic curvature of ultraspinning black hole is negative which means the ultraspinning black hole is likely to present an attractive between its molecules phenomenologically if we accept the analogical observation that the thermodynamic curvature reflects the interaction between molecules in a black hole system. Meanwhile we obtain a general conclusion that the thermodynamic curvature of the extreme black hole of the super-entropic black hole has a (positive or negative) remnant approximately proportional to the reciprocal of entropy of the black hole.

Drag and diffusion coefficients are calculated from an effective model based on chiral symmetry and heavy-quark effective theory, and utilized in a relativistic Langevin simulation to obtain transverse-momentum spectra and elliptic flow (v_2) of c- and b-quarks. The hadronization to D- and B-mesons is described by coalescence and fragmentation, and the resulting decay-electron spectra are compared to recent RHIC data.

description: We present a full derivation of the interaction Hamiltonian for holes in silicon within the six-band envelope-function scheme, which appropriately describes the valence band close to the $\boldsymbolΓ$ point. The full structure of the single-hole eigenstates is taken into account, including the Bloch part. The scattering processes caused by the Coulomb interaction are shown to be both intraband and interband, the latter being mostly short-ranged. In the asymptotic long-range limit, the effective potential tends to the screened Coulomb potential, and becomes purely intraband, as assumed in previous models. We apply our model to compute the excitation spectra of two interacting holes in prototypical silicon quantum dots, taking into account different dielectric environments. It is shown that, in the highly screened regime, short-range interactions (both intra- and inter-band) can be very relevant, while they lose importance when there is no screening other than the one proper of the bulk silicon crystal. In the latter case, we predict the formation of hole Wigner molecules.

Systems of Local Self-Administration after Agricultural Transformation - Experiences of a Local Resource Management Project in East Germany

Year: 2002
Subjects: Agricultural and Food Policy

description: This article raises the question of the constitution of rural society in postsocialist countries, and explores the possibilities of participatory approaches in rural development and resource management in face of given social conditions in the local context. The unifying scientific "idea" is currently associated with the concept of social capital. The ability to form social capital can be seen as a central prerequisite both for economic development and the protection of resources (that is, for sustainable development). An important element of this concept is the networking of the actors within the region and with external actors. As a result of historical development the network relations in the rural areas of East Germany have a specific structure. What is especially remarkable is the continuing dominant role of the representatives of the big agricultural enterprises in the important local network structures despite the obvious decline in the economic importance of these enterprises. The structures uncovered in the case studies can certainly be taken to reflect the reality of many local contexts. It is argued that, as far as the creation of the beginnings of participation in rural development and resource management are concerned, that if the peculiarities are ignored there is a danger that the existing network structures wills simply be strengthened through participatory development. Therefore, the important contributions of participatory approaches to the solution of concrete problems must be supplemented by the prospect of its social embedding in the context of rural development. At the same time it also became clear in the project that the success of developed attempts at problem solution can only be ensured if the higher political levels are prepared to devolve downwards.

description: While the notion of chaos is well established for dynamical systems on manifolds, it is not so for dynamical systems over discrete spaces with $ N $ variables, as binary neural networks and cellular automata. The main difficulty is the choice of a suitable topology to study the limit $N\to\infty$. By embedding the discrete phase space into a Cantor set we provided a natural setting to define topological entropy and Lyapunov exponents through the concept of error-profile. We made explicit calculations both numerical and analytic for well known discrete dynamical models.

Institutional Options for Sustainable Irrigation: An Evidence from Bulgaria

Publisher: name: Unknown

Subjects: Crop Production/Industries

description: This paper investigates a local problem of common pool resources (CPR), the solution of which needs a balance between the collective and private interests. In the political context we have a large group of actors with a short planning horizon and a lack of trust among them. CPR provision is organised in a centralised way. The state enforcement mechanism is weak and cannot protect the individuals or eventually back the collective decisions. The above problem is investigated in the case of irrigation in Bulgaria where water usage declined by nearly 85% during the period of transition. In addition, large parts of the existing canal systems were abandoned. Three groups of institutional options are investigated in the paper: improvement of the local level co-ordination; limiting the market imperfections, and strengthening the external conflict resolution and sanctioning mechanisms. The investigation of the above case led the author to conclusions that can be generalised for the case of CPR management during the period of transition. The transition process is not just a process of transferring western institutions to Eastern Europe, but also a process of spontaneous emerging of new institutions at local level. Therefore, we call for state intervention, not in the area of CPR provision, but in supporting local co-ordination.

description: During the post-socialist transition period, the Bulgarian irrigation facilities deteriorated to a large extent and no longer meet the needs of the new landowner and agricultural production structure. The Bulgarian government therefore enacted two new laws to encourage collective action and to establish water user associations in order to achieve sustainable water management. In this article, we will question the frequent argument that water user associations could easily be established in Bulgaria, because they are rooted in the water syndicates. Empirical findings from village case studies reveal that limited collective memory exists today about former water syndicates' rules-in-use and patterns of action. We will explain this breach of tradition by the migration from villages to cities, the suppression of procommunist so-called capitalist behaviour, and the length of the communist period. Moreover, the analysis of the historical cooperative development in Bulgaria shows that the water syndicates were enforced by a top-down approach and did not have much in common with the classic cooperative principles.

description: High-precision time synchronization for remote clocks plays an important role in fundamental science and real-life applications. However, the current time synchronization techniques have been shown to be vulnerable to sophisticated adversaries. There is a compelling need for fundamentally new methods to distribute high-precision time information securely. Here we propose a satellite-based quantum-secure time transfer (QSTT) scheme based on two-way quantum key distribution (QKD) in free-space, and experimentally verify the key technologies of the scheme via the Micius quantum satellite. In QSTT, a quantum signal (e.g., single photon) is used as the carrier for both the time transfer and the secret-key generation, offering quantum-enhanced security for transferring time signal and time information. We perform a satellite-to-ground time synchronization using single-photon-level signals and achieve a quantum bit error rate of less than 1%, a time data rate of 9 kHz and a time-transfer precision of 30 ps. These results offer possibilities towards an enhanced infrastructure of time-transfer network, whose security stems from quantum physics.

description: Bt-corn, a genetically engineered insect resistant variety, has been adopted by almost one-quarter of all corn farmers, resulting in economic impacts on both conventional corn growers and Bt-corn growers. we estimate changes in profits for both types of farmers with different levels of seed premiums, yield increases and adoption rates. We find that Bt-corn growers will see their profits decline when the adoption rate and seed premium are high, if they are not offset by higher yields. Conventional corn growers will always experience a decline in profits because the yield increase from Bt-corn causes corn price to fall.
Monetary Fines in EU Mergers: In Need for More Regulation
Creators: name: Memeti, Nora
Publisher: name: Market and Competition Law Review
Year: 2019

description: Monetary fines represent an important instrument to address violations of Competition Law. The European Commission (EC) and the EU Courts have been primarily engaged in imposing fines in cases of breach of the first pillar, and have rarely dealt with cases of abuse based on the fining guidelines issued in accordance with Article 23(2) of Regulation 1/2003. Compared to the first two pillars, mergers have not received similar scholarly attention.1 2 Since 2017, the EC has expressed a growing interest in investigating and imposing significant fines to mergers and acquisitions in breach of procedural matters. Therefore this article addresses the application of Article 14 of the European Union Merger Regulation (EUMR) in imposing fines to mergers with European Union (EU) dimension. The EC decisions and EU Courts’ judgments related to fines on mergers in breach of procedural matters are discussed in four specific sections. The first section analyses article 14(1) of the EUMR, which empowers the EC to impose a fine of up to 1% of the total turnover in the preceding business year on undertakings for breach of procedural matters, including, among others, for providing incorrect or misleading information. This section will address the case of Facebook as the first case in which the EC imposed fines based on the new EUMR. In this case, although the undertakings mislead the EC, based on the offered cooperation, the Authority decided to reduce the fine. In addition, it is also important to address the legal basis applied by the EC in accepting the offered cooperation as a mitigating factor and whether this may develop into a guiding “precedent” in the future. The second section deals with five cases of violations of articles 4(1) and 7(1) EUMR related to fines prescribed in article 14(2) EUMR. With regards to four of them, judgments of EU Courts and decisions of the EC and National Competition Authority (NCA) are analysed. The fifth case, the one on Ernst and Young, provides for the first preliminary ruling on the notion of “gun-jumping”. The third section deals with Article 14(3) and the fining methods on mergers. By reviewing each of these five cases, it is important to address factors taken into consideration when imposing fines. An obvious deficiency is the absence of a legal basis, regardless of whether manifested in hard or soft law. Here it is relevant to inquire in what manner the EC imposes fines and why it occasionally mirrors the fining guidelines applicable to other pillars of EU Competition Law. The last point to be addressed is the one of policy and the need to balance EC discretional powers and relevant legal principles such as legal certainty, equal treatment, transparency, and consistency.3 The fourth section provides for concluding remarks.

description: Bayesian Likelihood-Free Inference (LFI) approaches allow to obtain posterior distributions for stochastic models with intractable likelihood, by relying on model simulations. In Approximate Bayesian Computation (ABC), a popular LFI method, summary statistics are used to reduce data dimensionality. ABC algorithms adaptively tailor simulations to the observation in order to sample from an approximate posterior, whose form depends on the chosen statistics. In this work, we introduce a new way to learn ABC statistics: we first generate parameter-simulation pairs from the model independently on the observation; then, we use Score Matching to train a neural conditional exponential family to approximate the likelihood. The exponential family is the largest class of distributions with fixed-size sufficient statistics; thus, we use them in ABC, which is intuitively appealing and has state-of-the-art performance. In parallel, we insert our likelihood approximation in an MCMC for doubly intractable distributions to draw posterior samples. We can repeat that for any number of observations with no additional model simulations, with performance comparable to related approaches. We validate our methods on toy models with known likelihood and a large-dimensional time-series model.

This approach reproduces the precise value obtained by the other authors using the exact mode-sum method or the method of mirror images. The approximation is also in good agreement with the exact result in the three-dimensional case. We also evaluate the energy density of a conformally invariant scalar field around a global monopole by the same way and find the known result again.

The specifics of transport in this regime - a hierarchical sequence of avalanches of transferred charges, interrupted by "quiet" periods - make the counting statistics strongly non-Gaussian. We support our findings for the counting statistics as well as for the frequency-dependent noise power by numerical simulations, finding excellent agreement.

We introduce an idealized quantum-mechanical model of a charged particle that is periodically illuminated by pulses of laser light resulting in repeated indirect measurements of the approximate position of the particle. For this model we present a mathematically rigorous analysis of the appearance of particle tracks, assuming that the Hamiltonian of the particle is quadratic in the position- and momentum operators, as for a freely moving particle or a harmonic oscillator.

description: This paper determines the impact of food industry market power on farmers' incentive to promote in a situation where funds for promotion are raised through a per-unit assessment on farm output and food industry technology is characterized by variable proportions. Specifically, building on earlier studies by Azzam and by Holloway, Muth's model is extended to consider the farm-level impacts of generic advertising when downstream firms possess oligopoly and/or oligopsony power and advertising expenditure is endogenous at the market level. Applying the model to the U.S. beef industry, we find that for plausible parameter values market power reduces farmers' incentive to promote. However, the disincentive is moderated by factor substitution, and effectively vanishes as the factor substitution elasticity approaches the retail demand elasticity. This suggests that the Dorfman-Steiner theorem, suitably modified to account for factor substitution, suffices to indicate optimal advertising intensity in the U.S. beef sector.

Após a elaboração do enquadramento, em termos teóricos, do envelhecimento e da institucionalização, bem como do significado de apoio social, sua operacionalidade e características, define-se o enquadramento metodológico, a partir da caracterização da população em estudo, método de selecção da amostra, até apresentar os objectivos e hipóteses a analisar e o instrumento de recolha de informação apropriado para atingir esses objectivos. A análise dos dados recolhidos permite determinar as diferenças entre a percepção dos idosos institucionalizados sobre as dimensões do apoio social, bem como a relação entre as variáveis sócio-demográficas, o tempo de institucionalização, a adaptação do idoso à instituição, a sua saúde e a religião, com o apoio social e as suas diferentes dimensões.

description: When contract production is marketed contemporaneously with production sold through a spot market, it is conveninet to specify the contract price in terms of the subsequent cash price. This paper examines the competitive implications of such pricing arrangements, focusing in particular upon so-called "top-of-the-market (TOMP) pricing in cattle procurement, wherein the contract guarantees the producer the highest cash price prevailing at the time of delivery. We show that these contracts have anticompetitive consequences when the same buyers who purchase cattle with the TOMP clause also compete to procure cattle in the subsequent spot market. By committing to purchase cattle at a price to be determined later, beef packers' incentives to compete aggressively in the spot market are attenuated. Although TOMP pricing is not in producers' collective interest, rational sellers may nonetheless sign these contracts, in some cases with little or no financial inducement.

In this thesis, functional mutants of LCAT were utilized to study the factors influencing interaction of this protein with the plasma lipoproteins. McArdle 7777 cells were used to produce LCAT from a hepatic derived expression system. The expressed enzyme was uniformly glycosylated with biantennary oligosaccharide residues, which was significantly different from the glycosylation pattern observed in the plasma LCAT and the baby hamster kidney (BHK) expressed LCAT. Despite the differences in the glycosylation architecture, the new recombinant LCAT (rLCAT) displays similar kinetic properties to those of the plasma and BHK LCATs, suggesting that the differences in glycosylation architecture may not influence activity of the enzyme. Subsequently, interaction of rLCAT with lipoprotein substrates was studied to determine the binding characteristics of wild type (WT) and fish-eye disease (FED) plasma LCAT in vivo, and rLCAT in vitro. Endogenous LCAT was shown to remain bound to low-density lipoprotein (LDL) as well as HDL and that beta and alpha LCAT activity co-eluted with LDL and HDL particles, respectively. In vitro binding studies with whole plasma, total lipoproteins, and individual lipoproteins showed no differential association of rLCAT, either WT or FED (T123I), with HDL and LDL particles and that the majority of rLCAT did not bind to the plasma lipoproteins. BIAcore experiments using native plasma lipoproteins and proteoliposmes also showed little or no association of rLCAT with plasma lipoproteins, but a strong association with the synthetic HDL analogue particles. The final aspect of this thesis was concerned with the relationship of LCAT mutations with its structural and functional characteristics involving the study of two very unique mutations, which result in an increase in the LCAT activity. The kinetic data obtained from this study showed that the combination of the two mutations did not have an additive effect, but in fact resulted in reduction of LCAT activity. Although this effect may be due to lack of independence in mechanism of action or inability of the protein to tolerate sequence alterations, it suggests that the fourth oligosaccharide chain may influence LCAT function in more ways than just inhibiting substrate accessibility. In conclusion, although the glycosylation architecture of LCAT does not significantly alter the kinetic properties of the recombinant protein, it may influence binding/association of rLCAT to the plasma lipoproteins. In addition, the fourth oligosaccharide moiety of LCAT may play an important role (other than inhibitory) in LCAT activity.

description: This paper examines technology benefit allocation between an innovating firm and heterogeneous technology adopters. Using a triangular distribution of adopter innovation value, we find that as the upper bound increases, optimal innovation price increases, but at a slower rate. Similarly, as the lower bound decreases, price decreases and producer benefits increase. Finally, greater producer heterogeneity leads to greater producer benefits from innovation in non-competitive markets. An empirical application of the model is considered, bovine somatotropin adoption on dairy farms. The model generates an intuitive explanation of the common finding that average adopters are making zero or negative profits.

description: We give a complete solution to an open problem of Thomas Cover in 1987 about the capacity of a relay channel in the general discrete memoryless setting without any additional assumptions. The key step in our approach is to lower bound a certain soft-max of a stochastic process by convex geometry methods, which is based on two ideas: First, the soft-max is lower bounded in terms of the supremum of another process, by approximating a convex set with a polytope with bounded number of vertices. Second, using a result of Pajor, the supremum of the process is lower bounded in terms of packing numbers by means of mixed-volume inequalities (Minkowski's first inequality).

description: Let $Ξ$ be a discrete set in ${\mathbb{R}}^d$. Call the elements of $Ξ$ centers. The well-known Voronoi tessellation partitions ${\mathbb{R}}^d$ into polyhedral regions (of varying sizes) by allocating each site of ${\mathbb{R}}^d$ to the closest center. Here we study ``fair'' allocations of ${\mathbb{R}}^d$ to $Ξ$ in which the regions allocated to different centers have equal volumes. We prove that if $Ξ$ is obtained from a translation-invariant point process, then there is a unique fair allocation which is stable in the sense of the Gale--Shapley marriage problem. (I.e., sites and centers both prefer to be allocated as close as possible, and an allocation is said to be unstable if some site and center both prefer each other over their current allocations.) We show that the region allocated to each center $ξ$ is a union of finitely many bounded connected sets. However, in the case of a Poisson process, an infinite volume of sites are allocated to centers further away than $ξ$. We prove power law lower bounds on the allocation distance of a typical site. It is an open problem to prove any upper bound in $d>1$.

description: Enquadramento: As mudanças de políticas na saúde e as alterações na profissão e carreira de enfermagem interferem na dinâmica e estabilidade futura dos enfermeiros. O presente estudo teve como objetivo conhecer alguns fatores determinantes das estratégias de resolução de conflitos adotadas pelos enfermeiros. Material e Método: Realizou-se um estudo de natureza quantitativa, descritivo-correlacional e transversal, com recurso a uma amostra não probabilística e por conveniência, composta por com 102 enfermeiros a exercer funções em Unidades de Saúde, maioria do sexo feminino (82,4%) e com idade média de 39,33 anos e desvio padrão 9,226. O instrumento de colheita de dados incorporou três escalas aferidas e validadas para a população portuguesa: Questionário Empenhamento Organizacional, Escala Empenhamento Profissional e Inventário Estratégias de Resolução de Conflitos que avalia como os indivíduos lidam com as situações conflituais perante superiores (Forma A), subordinados (Forma B) e colegas (Forma C). Resultados: A maioria dos enfermeiros apresenta scores moderados a elevados de empenhamento organizacional e profissional. Confirmam-se as hipóteses de que algumas variáveis sociodemográficas e profissionais predizem as estratégias de resolução de conflitos adotadas pelos enfermeiros. Há uma correlação positiva entre idade e estratégia evitação face ao chefe; género e estratégia dominação face aos subordinados; formação em gestão e estratégia dominação face ao chefe e subordinados; categoria profissional de enfermeiro e enfermeiro graduado e estratégia evitação face ao chefe e aos colegas; local de trabalho e estratégia dominação face ao chefe, subordinados e colegas; tempo de serviço e estratégia evitação face ao chefe e aos colegas. O empenhamento organizacional e o empenhamento profissional estão positivamente correlacionados entre si e determinam as estratégias de resolução de conflitos adotadas pelos enfermeiros. Conclusão: Os resultados asseguram a necessidade favorecer e estimular o empenhamento afetivo pelas consequências positivas que ele acarreta na organização e na profissão. O desempenho organizacional beneficia com a estimulação do conflito sob determinadas condições e que a gestão construtiva dos conflitos é um elemento essencial para a eficácia organizacional

description: This research examines risk-return tradeoffs across a full range of crop insurance products and coverage levels. Results indicate that farm-level products reduce risk for low probability events, but that risk reductions often are not large for events that occur with more regularity. Risk reductions vary with yield variability; with counties that have higher yield variability also experiencing greater risk reductions through the use of crop insurance.

description: This paper examines domestic and international food market integration in Russia before and after the financial crisis of 1998. Using monthly prices of bread, pork, and beef in 80 regions of Russia from 1994 to 1999, we measure the short-run response of regional prices to changes in foreign prices and domestic inflation. We find that both changes in foreign prices and domestic inflation have distinct impacts on the prices of these commodities in different Russian markets, indicating poor market integration in the short run. An analysis of the effect of the financial crisis shows that market integration for bread and beef deteriorated after the crisis. However, integration improved for pork in some parts of Russia, and the integration of Siberian pork markets with Chinese pork markets also improved after the crisis.
