description: Urbanization means the growth of the number and size of the towns and the spreading of quality of life in towns (Enyedi, 1996). Naturally the growth and development is different in several parts of the world. On the other hand the urbanization is not only effect to towns. It has also an effect on rural region. Several attendant phenomenons belong to the urbanization (economic development, rural development, infrastructural development etc.). Primary target is to demonstrate the connection between urbanization and rural development.

description: The external costs of electricity generation can be characterised by the resulting social and environmental impacts. The most significant impacts are the air pollutions impact on health, built in environment, crops, forests, agricultural areas and on global warming. The primary impact considered is the air pollution’s effect on human health. The monetised value of the health impact, the external costs are calculated for two regional coal power plants, the effects are examined on the EU level with the ExternE methodology.

description: A systematic study of terminating states in A$\sim$50 mass region using the self-consistent Skyrme-Hartree-Fock model is presented. The objective is to demonstrate that the terminating states, due to their intrinsic simplicity, offer unique and so far unexplored opportunities to study different aspects of the effective NN interaction or nuclear local energy density functional. In particular, we demonstrate that the agreement of the calculations to the data depend on the spin fields and the spin-orbit term which, in turn, allows to constrain the appropriate Landau parameters and the strength of the spin-orbit potential.

subject: international comparison

description: The local, regional and global economic and natural phenomena of previous decades collectively emphasize the growing importance of risk factors affecting agricultural production both directly and indirectly. Agricultural producers should not restrict their risk management strategies to offset and relieve the problems caused by climatic and natural phenomena, but the knowledge of up-to-date professional, market, and agricultural policy developments is more and more an indispensable condition of successful farming. Besides what mentioned above, it is at least equally important to answer the question of how farmers perceive the importance of risk factors surrounding their activities, as it strongly influences the shaping of their risk management strategies. The responsibility of professional organizations and policy makers is easily shapeable in this sense because they may play an important role in the orientation and education of farmers, thus making it possible that farmers judge the importance of risk factors properly so they may work out adequate risk management strategies. The European Union has long been aware of the importance of the topic and makes great efforts to investigate the possibilities of an EU level risk management system. The “Design and economic impact of risk management tools for European agriculture” research project1 conducted under the aegis of the Sixth Framework Programme fits that objective. Within the project the authors of this paper explored the risk perception and applied risk management strategies of farmers in selected EU Member States.

description: We have performed detailed photoluminescence (PL) and absorption spectroscopy on the same single self-assembled quantum dot in a charge-tunable device. The transition from neutral to charged exciton in the PL occurs at a more negative voltage than the corresponding transition in absorption. We have developed a model of the Coulomb blockade to account for this observation. At large negative bias, the absorption broadens as a result of electron and hole tunneling. We observe resonant features in this regime whenever the quantum dot hole level is resonant with two-dimensional hole states located at the capping layer-blocking barrier interface in our structure.

description: Agricultural production and agricultural policy has many special dimensions. The production structure, income positions, and labour input have large regional disparities, the production intensity is not homogenous in space, and farms have different risk factors and market possibilities in the different regions of Hungary. Land use and production technology also varies largely, in many regions farming is competitive, highly specialized with big corporate farms, while other regions have small individual farms with mixed production structure and less concentration in land use. There are no direct data for spatial analysis less aggregated than NUTS 3 level. Only the data of agricultural census and administrative database for direct payments are available at settlement and microregional level, but these databases do not provide information of farm income. The income statistics either cannot be disaggregated to micro-regional level (agricultural accounts) or are not representative at this level (FADN). The administrative database of the Paying Agency contains the land use data and limited livestock numbers for all farms receiving direct payments. The FADN database contains a large accountancy dataset for a low number of farms. Statistical matching combines these two databases and provides a possibility for detailed regional analysis using estimated data.
Why RKKY exchange integrals are inappropriate to describe ferromagnetism in diluted magnetic semiconductors

Publisher: name: arXiv

description: We calculate Curie temperatures and study the stability of ferromagnetism in diluted magnetic materials, taking as a model for the exchange between magnetic impurities a damped Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction and a shor t range term representing the effects of superexchange. To properly include effects of spin and thermal fluctuations as well as geometric disorder, we solve the effective Heisenberg Hamiltonian by means of a recently developed semi-analytical approach. This approach, ``self-consistent local Random Phase Approximation (SC-L RPA)'', is explained. We show that previous mean-field treatments, which have been widely used in the literature, largely overestimate both the Curie temperatures and the stability of ferromagnetism as a function of carrier density. The discr epancy when compared to the current approach was that effects of frustration in RKKY oscillations had been strongly underestimated by such simple mea n-field theories. We argue that the use, as is frequent, of a weakly-disordered RKKY exchange to model ferromagnetism in diluted III-V systems is inconsistent with the observation of ferromagnetism over a wide region of itinerant carrier densities. This may be puzzling when compared to the apparent success of calculations based on {\it ab-initio} estimates of the coupling; we propose a resolution to this issue by taking RKKY-like interactions between resonant states close to the Fermi level.

description: We present numerical simulations of acoustic wave propagation in confined granular systems consisting of particles interacting with the three-dimensional Hertz-Mindlin force law. The response to a short mechanical excitation on one side of the system is found to be a propagating coherent wavefront followed by random oscillations made of multiply scattered waves. We find that the coherent wavefront is insensitive to details of the packing: force chains do not play an important role in determining this wavefront. The coherent wave propagates linearly in time, and its amplitude and width depend as a power law on distance, while its velocity is roughly compatible with the predictions of macroscopic elasticity. As there is at present no theory for the broadening and decay of the coherent wave, we numerically and analytically study pulse-propagation in a one-dimensional chain of identical elastic balls. The results for the broadening and decay exponents of this system differ significantly from those of the random packings. In all our simulations, the speed of the coherent wavefront scales with pressure as $p^{1/6}$; we compare this result with experimental data on various granular systems where deviations from the $p^{1/6}$ behavior are seen. We briefly discuss the eigenmodes of the system and effects of damping are investigated as well.

description: Future galaxy surveys will provide accurate measurements of the matter power spectrum across an unprecedented range of scales and redshifts. The analysis of these data will require one to accurately model the imprint of non-linearities of the matter density field. In particular, these induce a non-Gaussian contribution to the data covariance that needs to be properly taken into account to realise unbiased cosmological parameter inference analyses. Here, we study the cosmological dependence of the matter power spectrum covariance using a dedicated suite of N-body simulations, the Dark Energy Universe Simulation - Parallel Universe Runs (DEUS-PUR) {\it Cosmo}. These consist of 512 realizations for 10 different cosmologies where we vary the matter density $Ω_m$, the amplitude of density fluctuations $σ_8$, the reduced Hubble parameter $h$ and a constant dark energy equation of state $w$ by approximately $10\%$. We use these data to evaluate the first and second derivatives of the power spectrum covariance with respect to a fiducial $Λ$CDM cosmology. We find that the variations can be as large as $150\%$ depending on the scale, redshift and model parameter considered. By performing a Fisher matrix analysis we explore the impact of different choices in modelling the cosmological dependence of the covariance. Our results suggest that fixing the covariance to a fiducial cosmology can significantly affect the recovered parameter errors and that modelling the cosmological dependence of the variance while keeping the correlation coefficient fixed can alleviate the impact of this effect.

Three Components Evolution in a Simple Big Bounce Cosmological Model

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We consider a five-dimensional Ricci flat Bouncing cosmology and assume that the four-dimensional universe is permeated smoothly by three minimally coupled matter components: CDM+baryons $ρ_{m}$, radiation $ρ_{r}$ and dark energy $ρ_{x}$. Evolutions of these three components are studied and it is found that dark energy dominates before the bounce, and pulls the universe contracting. In this process, dark energy decreases while radiation and the matter increase. After the bounce, the radiation and matter dominates alternatively and then decrease with the expansion of the universe. At present, the dark energy dominates again and pushes the universe accelerating. In this model, we also obtain that the equation of state (EOS) of dark energy at present time is $w_{x0}\approx -1.05$ and the redshift of the transition from decelerated expansion to accelerated expansion is $z_{T}\approx 0.37$, which are compatible with the current observations.

description: Comparison of P-P total cross-sections estimations at very high energies - from accelerators and cosmic rays - shows a disagreement amounting to more than 10 %, a discrepancy which is beyond statistical errors. Here we use a phenomenological model based on the Multiple-Diffraction approach to successfully describe data at accelerator energies. The predictions of the model are compared with data On the basis of regression analysis we determine confident error bands, analyzing the sensitivity of our predictions to the employed data for extrapolation. : using data at 546 and 1.8 TeV, our extrapolations for p-p total cross-sections are only compatible with the Akeno cosmic ray data, predicting a slower rise with energy than other cosmic ray results and other extrapolation methods. We discuss our results within the context of constraints in the light of future accelerator and cosmic ray experimental results.

description: The analysis of the relation between modular P$_1$CT-symmetry -- a consequence of the Unruh effect -- and Pauli's spin-statistics relation is continued. The result in the predecessor to this article is extended to the Lorentz symmetric situation. A model $\G_L$ of the universal covering $\widetilde{L_+^\uparrow}\cong SL(2,\complex)$ of the restricted Lorentz group $L_+^\uparrow$ is modelled as a reflection group at the classical level. Based on this picture, a representation of $\G_L$ is constructed from pairs of modular P$_1$CT-conjugations, and this representation can easily be verified to satisfy the spin-statistics relation.

description: Main objective of the paper is to discover Hungary’s rural areas suffering from agricultural employment crisis and to compare them to the spatial inequalities, examining the development possibilities and the adaptability to new economic and social processes. The actuality of this objective has been given by the recent processes in the global, European and Hungarian economy, the growing importance of local development and endogenous resources, the decreasing role of agriculture in total employment, and the general problems of rural areas. Based on multivariable statistical methods (factorial-, discriminant- and cluster analyses) and the data of 15 years before the EU accession, the selected micro-regions could be reliable separated by the economical state and social situation, the education, and the dependence on the agriculture. It can be stated that the concentrated, long-term agricultural unemployment is in close correlation to territorial inequalities, due to the unfavorable demographic and educational structure of the labor-force leaving the agriculture, the inadequate local resources, the underdevelopment and the lack of other possibilities of employment common to the identified micro-regions.

description: Nutrient management and air emissions continue to be an area of increased management control on all livestock operations as environmental regulations become more stringent. Agricultural producers must consider uncertainty surrounding the timing of and potential increases of environmental policy controls, such as emission taxes, when making future investment decisions. An optimal control theory framework was applied to a dairy farm facing an uncertain increase in emission taxes and an unknown date at which emission taxes will take effect. The optimal investment path considering these uncertainties was solved implicitly and compared to a full certainty case.

description: Background: Diagnostic DNA arrays for detection of point mutations as markers for cancer usually function in the presence of a large excess of wild type DNA. This excess can give rise to false positives due to competitive hybridization of the wild type target at the mutation spot. The analysis of the DNA array data is typically qualitative aiming to establish the presence or absence of a particular point mutation. Our theoretical approach yields methods for quantifying the analysis so as to obtain the ratio of concentrations of mutated and wild type DNA. Method: The theory is formulated in terms of the hybridization isotherms relating the hybridization fraction at the spot to the composition of the sample solutions at thermodynamic equilibrium. It focuses on samples containing an excess of single stranded DNA and on DNA arrays with low surface density of probes. The hybridization equilibrium constants can be obtained by the nearest neighbor method. Results: Two approaches allow us to obtain quantitative results from the DNA array data. In one the signal of the mutation spot is compared with that of the wild type spot. The implementation requires knowledge of the saturation intensity of the two spots. The second approach requires comparison of the intensity of the mutation spot at two different temperatures. In this case knowledge of the saturation signal is not always necessary. Conclusions: DNA arrays can be used to obtain quantitative results on the concentration ratio of mutated DNA to wild type DNA in studies of somatic point mutations.

Brans-Dicke cosmology with a $Λ$- term: a possible solution to $Λ$CDM tensions

description: We present a full-fledged analysis of Brans-Dicke cosmology with a cosmological constant and cold dark matter (BD-$Λ$CDM for short). We extend the scenarios where the current cosmological value of the BD-field is restricted by the local astrophysical domain to scenarios where that value is fixed only by the cosmological observations, which should be more natural in view of the possible existence of local screening mechanims. Our analysis includes both the background and perturbations equations in different gauges. We find that the BD-$Λ$CDM is favored by the overall cosmological data as compared to the concordance GR-$Λ$CDM model, namely data on distant supernovae, cosmic chronometers, local measurements of the Hubble parameter, baryonic acoustic oscillations, Large-Scale Structure formation and the cosmic microwave background under full Planck 2018 CMB likelihood. We also test the impact of Strong and Weak-Lensing data on our results, which can be significant. We find that the BD-$Λ$CDM can mimic effective quintessence with a significance of about $3-3.5σ$ c.l. (depending on the lensing datasets). The fact that the BD-$Λ$CDM behaves effectively as a Running Vacuum Model (RVM) when viewed from the GR perspective helps to alleviate some of the existing tensions with the data, such as the $σ_8$ excess predicted by GR-$Λ$CDM. On the other hand, the BD-$Λ$CDM model has a crucial bearing on the acute $H_0$-tension with the local measurements, which is rendered virtually harmless owing to the small increase of the effective value of the gravitational constant with the expansion. The simultaneous alleviation of the two tensions is a most remarkable feature of BD-gravity with a cosmological constant in the light of the current observations, and hence goes in support of BD-$Λ$CDM against GR-$Λ$CDM

description: Brazil now is the largest coffee, sugar, and fruit juice producer, second-largest soybean and beef producer, and third-largest corn and broiler producer. It has overtaken the U.S. in poultry exports, nearly matches the U.S. in soybean exports, and dominates global trade in frozen orange juice. To test and better understand these advances, we draw on decennial farm censuses to examine technical change and efficiency in Brazilian agriculture. Our approach is to estimate a stochastic, multi-product, output distance frontier, using a translog functional form and data disaggregated to the micro-region (sub-state) level. Using two consecutive decennial farm censuses, we combine state-level Fisher productivity-change indexes with state-level translog distance function estimates of technical efficiency change to impute state-level technical shifts. We find, leading up to the soon-to-be-released 2006 agricultural census, that Brazil’s multi-factor productivity growth rate between 1985 and 1996 was 20.2%. Mean state-level technical efficiency was 91.2%, which implies the production frontier expanded 22.2% over the reference time period.

description: Hypothetical bias arises when values which people say they place on a good or service differ systematically from the values people reveal for the same good or service through actual, binding economic transactions. Studies of hypothetical bias with respect to public goods often use charitable contributions or other relatively unique goods and these studies employ a variety of mechanisms to elicit the stated and revealed values. This study proposes the inclusion of a free-rider barring random dictatorship mechanism in the standard public contribution game to investigate the issue of bias when a public good involves immediate monetary returns to subjects. Steps are taken to make the game have the look and feel of a real-world tradeoff between private investment and public good provision. Data for the experiment were collected using a sample of students from the University of Alberta. A statistically significant negative hypothetical bias is found for the first hypothetical and the first real rounds of the game. The bias decays in subsequent round pairs, oscillating around zero.
Moment resistant connections made with timber rivets in wood product substrates
Creators: name: Hampson, Joel Alexander
Publisher: name: University of British Columbia

description: The moment resistance is determined for connections made with timber (glulam) rivets. Designing a moment connection in wood and wood products is complicated by their non-linear (limited elastic) and anisotropic properties; there is currently no codified design guidance for moment connections in wood or wood products. Timber rivets are high-strength engineered nails. They are used in conjunction with predrilled steel side-plates. The wood product substrates investigated herein are glue-laminated, laminated-strand, laminated-veneer and parallel-strand lumber. The model is based on the principle of equilibrium and assumes that the connection will behave in a ductile - no sudden wood failure - manner. The moments within a connection (a group of fasteners) is summed about an instantaneous centre of rotation. The internal moment arises from the resistance of each fastener; this resistance is non-linear and displacement dependent; a Foschi-style load-slip equation and parameters are used to calculate this for each fastener. The external moment arises from the eccentrically applied load and its radius from the instantaneous centre of rotation; the general, a-priori loading can be converted into a wrench to find this eccentric load and lever arm. The instantaneous centre of rotation that minimizes the difference between the internal and external moments is found by an incremental search. MS Visual Basic was used to implement this search. The instantaneous centre of rotation, and subsequent moment capacity, was found for every degree of preset rotation up to an ultimate capacity. This was implemented for various arrangements of timber rivets and wood products. Experimental verification o f the model for these arrangements indicated the following: the ultimate was almost exactly predicted on average, and the yield loads and the rotational stiffness were under predicted by an average of about 10% and 30%, respectively. The instantaneous centre of rotation appeared in the predicted location. All of the specimens exhibited ductile behaviour during testing, but the side plate completely disengaged on the shortest-rivet laminated-strand and parallel-strand lumber samples. Further research is suggested in several areas: notably, the dynamic response of moment connections and linking the fastener's capacities to more fundamental properties like elastic-moduli and densities.

description: The impact of public and private transfers on credit markets has not been sufficiently studied and understanding any spill over effects caused by these transfers may be useful for policy makers. This paper estimates the impact of Conditional Cash Transfers (CCTs) and remittances received by poor households in rural Nicaragua on their decision to request a loan. We find that, on average, CCTs did not affect the request of credit while remittances increased it, controlling for potential endogeneity. We argue the reduction in income risk provided by remittances changes borrowers’ expected marginal returns to a loan and/or their creditworthiness, as perceived by lenders. The successful enforcement of the use of CCTs on long-term investments seems to have avoided externalities on the use of short-term credit these households have access to and their creditworthiness.

description: The purpose of this paper is to investigate the relationship between housing uncertainties, child time preferences and education outcomes in the form of staying in school. The paper tests the hypothesis that students who face housing uncertainties through mortgage foreclosures and evictions learn impatient behavior and are therefore at greater risk of dropping out of school, impeding human capital formation and economic development.

description: Precision measurements in molecules have advanced rapidly in recent years through developments in techniques to cool, trap, and control. The complexity of molecules makes them a challenge to study, but also offers opportunities for enhanced sensitivity to many interesting effects. Polyatomic molecules offer additional complexity compared to diatomic molecules, yet are still "simple" enough to be laser-cooled and controlled. While laser cooling molecules is still a research frontier itself, there are many proposed and ongoing experiments seeking to combine the advanced control enabled by ultracold temperatures with the intrinsic sensitivity of molecules. In this perspective, we discuss some applications where laser-cooled polyatomic molecules may offer advantages for precision measurements of fundamental physics, both within and beyond the Standard Model.

description: We investigate chiral symmetry restoration in finite spatial volume and at finite temperature by calculating the dependence of the chiral phase transition temperature on the size of the spatial volume and the current-quark mass for the quark-meson model, using the proper-time Renormalization Group approach. We find that the critical temperature is weakly dependent on the size of the spatial volume for large current-quark masses, but depends strongly on it for small current-quark masses. In addition, for small volumes we observe a dependence on the choice of quark boundary conditions.

description: We present chemical abundances of red giant branch (RGB) stars in the dwarf spheroidal (dSph) satellite system of Andromeda (M31), using spectral synthesis of medium resolution (R $\sim 6000$) spectra obtained with the Keck II telescope and DEIMOS spectrograph via the Spectroscopic and Photometric Landscape of Andromeda's Stellar Halo (SPLASH) survey. We coadd stars according to their similarity in photometric metallicity or effective temperature to obtain a signal-to-noise ratio (S/N) high enough to measure average [Fe/H] and [$α$/Fe] abundances. We validate our method using high S/N spectra of RGB stars in Milky Way globular clusters as well as deep observations for a subset of the M31 dSphs in our sample. For this set of validation coadds, we compare the weighted average abundance of the individual stars with the abundance determined from the coadd. We present individual and coadded measurements of [Fe/H] and [$α$/Fe] for stars in ten M31 dSphs, including the first [$α$/Fe] measurements for And IX, XIV, XV, and XVIII. These fainter, less massive dSphs show declining [$α$/Fe] relative to [Fe/H], implying an extended star formation history. In addition, these dSphs also follow the same mass-metallicity relation found in other Local Group satellites. The conclusions we infer from coadded spectra agree with those from previous measurements in brighter M31 dSphs with individual abundance measurements, as well as conclusions from photometric studies. These abundances greatly increase the number of spectroscopic measurements of the chemical composition of M31's less massive dwarf satellites, which are crucial to understanding their star formation history and interaction with the M31 system.
