BORDERS AS A POLITICAL AND SOCIOCULTURAL PHENOMENON IN THE CONTEXT OF CROSS-BORDER INTERACTIONS
Creators: name: Djalilova, Malika
Publisher: name: Zenodo
Year: 2024

description: Borders play a key role in shaping political geography and sociocultural interactions. Historically, borders were viewed as physical barriers protecting territorial sovereignty and national interests. However, under the conditions of globalization and changing perceptions of territoriality, borders have transformed into dynamic zones of interaction, where cultural, economic, and political processes intersect. Modern approaches to the study of borders, as demonstrated in the works of Robert Sack and David Newman, emphasize their social construction, which influences the formation of identity and international relations. This paper analyzes the evolution of border concepts and their role in cross-border interactions, with a focus on their significance in the face of global challenges such as migration and integration.

description: When liquid droplets nucleate and grow in a polymer network, compressive stresses can significantly increase their internal pressure, reaching values that far exceed the Laplace pressure. When droplets have grown in a polymer network with a stiffness gradient, droplets in relatively stiff regions of the network tend to dissolve, favoring growth of droplets in softer regions. Here, we show that this elastic ripening can be strong enough to reverse the direction of Ostwald ripening: large droplets can shrink to feed the growth of smaller ones. To numerically model these experiments, we generalize the theory of elastic ripening to account for gradients in solubility alongside gradients in mechanical stiffness.

description: An intense source of 37Ar was produced by the (n,alpha) reaction on 40Ca by irradiating 330 kg of calcium oxide in the fast neutron breeder reactor at Zarechny, Russia. The 37Ar was released from the solid target by dissolution in acid, collected from this solution, purified, sealed into a small source, and brought to the Baksan Neutrino Observatory where it was used to irradiate 13 tonnes of gallium metal in the Russian-American gallium solar neutrino experiment SAGE. Ten exposures of the gallium to the source, whose initial strength was 409 +/- 2 kCi, were carried out during the period April to September 2004. The 71Ge produced by the reaction 71Ga(nu_e,e^-)71Ge was extracted, purified, and counted. The measured production rate was 11.0 ^+1.0 _-0.9 (stat) +/- 0.6 (syst) atoms of 71Ge/d, which is 0.79 ^+0.09_-0.10 of the theoretically calculated production rate. When all neutrino source experiments with gallium are considered together, there is an indication the theoretical cross section has been overestimated.

description: This series of six reports entitled: "On-Farm Food Safety and Environmental Farm Plans: Identifying and Classifying Benefits and Costs" was initiated soon after the launch of the Agricultural Policy Framework (APF) in 2002. The APF recognized the importance of food safety and environmental concerns for the future growth of the agriculture and Agri-food sector. For this reason, Agriculture and Agri-Food Canada (AAFC) commissioned this series of reports to develop a conceptual framework to strengthen our understanding of the potential benefit and cost implications of On-farm Food Safety (OFFS) and Environmental Farm Plans (EFP) that were key components of the APF. The reports were prepared by a group of academics with extensive knowledge of the agriculture and Agri-food sector and issues related to food safety, traceability and the environment. The first report presents a summary of the findings in the five main reports in the series. The second report presents the conceptual framework that was developed to help identify qualitatively the potential benefits and costs that the various players in the agriculture and agri-food supply chain would face in implementing OFFS and EFP programs. The third report applies this framework to pork, the fourth, to beef, the fifth, to grains and the sixth, to dairy. In general, benefits and costs are divided into both demand and supply side effects. In addition, both public and private costs and benefits are considered, especially since they help indicate where a role for government might be required and where markets are not working as well as they might. Based on these preliminary qualitative assessments, the beef and pork sector have more to gain from HACCP-based OFFS and EFP initiatives, due to their ability to gain market share from marketing their products internationally, while the grains sector already benefits internationally from its high quality reputation and the dairy sector is restricted to produce only for the domestic market. However, more work is required in these areas to validate and quantify costs and benefits.

description: Dimensionality reduction (DR) algorithms, which reduce the dimensionality of a given data set while preserving the information of the original data set as well as possible, play an important role in machine learning and data mining. Duan \emph{et al}. proposed a quantum version of the A-optimal projection algorithm (AOP) for dimensionality reduction [Phys. Rev. A 99, 032311 (2019)] and claimed that the algorithm has exponential speedups on the dimensionality of the original feature space $n$ and the dimensionality of the reduced feature space $k$ over the classical algorithm. In this paper, we correct the time complexity of Duan \emph{et al}.'s algorithm to $O(\frac{κ^{4s}\sqrt{k^s}} {ε^{s}}\mathrm{polylog}^s (\frac{mn}ε))$, where $κ$ is the condition number of a matrix that related to the original data set, $s$ is the number of iterations, $m$ is the number of data points and $ε$ is the desired precision of the output state. Since the time complexity has an exponential dependence on $s$, the quantum algorithm can only be beneficial for high dimensional problems with a small number of iterations $s$. To get a further speedup, we propose an improved quantum AOP algorithm with time complexity $O(\frac{s κ^6 \sqrt{k}}ε\mathrm{polylog}(\frac{nm}ε) + \frac{s^2 κ^4}ε\mathrm{polylog}(\frac{κk}ε))$ and space complexity $O(\log_2(nk/ε)+s)$. With space complexity slightly worse, our algorithm achieves at least a polynomial speedup compared to Duan \emph{et al}.'s algorithm. Also, our algorithm shows exponential speedups in $n$ and $m$ compared with the classical algorithm when both $κ$, $k$ and $1/ε$ are $O(\mathrm{polylog}(nm))$.

description: Detecting tremors is challenging for both humans and machines. Infants exposed to opioids during pregnancy often show signs and symptoms of withdrawal after birth, which are easy to miss with the human eye. The constellation of clinical features, termed as Neonatal Abstinence Syndrome (NAS), include tremors, seizures, irritability, etc. The current standard of care uses Finnegan Neonatal Abstinence Syndrome Scoring System (FNASS), based on subjective evaluations. Monitoring with FNASS requires highly skilled nursing staff, making continuous monitoring difficult. In this paper we propose an automated tremor detection system using amplified motion signals. We demonstrate its applicability on bedside video of infant exhibiting signs of NAS. Further, we test different modes of deep convolutional network based motion magnification, and identify that dynamic mode works best in the clinical setting, being invariant to common orientational changes. We propose a strategy for discharge and follow up for NAS patients, using motion magnification to supplement the existing protocols. Overall our study suggests methods for bridging the gap in current practices, training and resource utilization.

We find excellent agreement between the analytical model and micromagnetic simulation results for various magnetic parameters such as the magnetic field gradient, Gilbert damping constant. We also observe much faster velocity of the chiral domain wall (DW) motion. The chiral DW is exist with smaller interfacial Dzyaloshinskii-Moriya interaction energy density cases. These results provide to develop efficient control of skyrmion for spintronic devices.

description: In today’s world, rural areas are confronted with a spectrum of changes. These changes have multiple characters, varying from changes in ecosystem conditions to socioeconomic impacts, such as food- and financial crises. They present serious problems to rural management and largely affect future perspectives of rural areas. Rural resilience refers to the capacity of a rural region to adapt to changing external circumstances in such a way that a satisfactory standard of living is maintained, while coping with its inherent ecological, economic and social vulnerability. Rural resilience describes how rural areas are affected by external shocks and how it influences system dynamics. This paper further eradicates on this concept, by exploring in detail what the importance is of resilience theory within rural areas. An answer is tried to be given to the question how to detect resilience in rural areas, by reviewing the existing literature and to the question how to enhance resilient rural development. Finally questions are formulated for further research within the field of rural resilience.

description: We use the SnIa Gold dataset to compare LCDM with 10 representative parametrizations of the recent Hubble expansion history $H(z)$. For the comparison we use two statistical tests; the usual $χ_{min}^2$ which is insensitive to the parametrization number of parameters, and a statistic we call the p-test which depends on both the value of $χ_{min}^2$ and the number $n$ of the parametrization parameters. The p-test measures the confidence level to which the parameter values corresponding to LCDM are excluded from the viewpoint of the parametrization tested. For example, for a linear equation of state parametrization $w(z)=w_0 + w_1 z$ the LCDM parameter values ($w_0=-1$, $w_1=0$) are excluded at 75% confidence level. We use a flat prior and $Ω_{0m}=0.3$. All parametrizations tested are consistent with the Gold dataset at their best fit. According to both statistical tests, the worst fits among the 10 parametrizations, correspond to the Chaplygin gas, the brane world and the Cardassian parametrizations. The best fit is achieved by oscillating parametrizations which can exclude the parameter values corresponding to LCDM at 85% confidence level. Even though this level of significance does not provide a statistically significant exclusion of LCDM (it is less than $2σ$) and does not by itself constitute conclusive evidence for oscillations in the cosmological expansion, when combined with similar independent recent evidence for oscillations coming from the CMB and matter power spectra it becomes an issue worth of further investigation.

description: Universal quantum information processing requires single-qubit rotations and two-qubit interactions as minimal resources. A possible step beyond this minimal scheme is the use of three-qubit interactions. We consider such three-qubit interactions and show how they can reduce the time required for a quantum state transfer in an XY spin chain. For the experimental implementation, we use liquid-state nuclear magnetic resonance (NMR), where three-qubit interactions can be implemented by sequences of radio-frequency pulses.

description: We study a class of extended quintessence cosmologies where the scalar field playing the role of the dark energy is exponentially coupled to the Ricci scalar. We find that the dynamics induced by the effective gravitational potential in the Klein-Gordon equation dominates the motion of the field in the early universe. The resulting "R-boost" trajectory is characterized by a kinetic dark energy density, given by [3\rhomnr0(1+z)]^2 [ 32 rhor0 omegaJBD0]^(-1), where omegaJBD0, rhor0 and rhomnr0 are calculated at present, and represent the Jordan Brans Dicke parameter, the density of relativistic matter and of those species which are non-relativistic at redshift z, respectively. We show that such a trajectory represents an attractor, equivalent to a tracking solution with equation of state w=-1/3, providing a large basin of attraction for the initial dark energy density regardless of the properties of the potential energy yielding acceleration today. We derive the up to date constraints from Big Bang Nucleosynthesis (BBN) on the present scenario, and we show that they are largely satisfied for interesting trajectories of the dark energy scalar field in the early universe. We compute the cosmological perturbation spectra in these cosmologies. For a fixed value of omegaJBD0, the projection and Integrated Sachs-Wolfe effects on the cosmic microwave background anisotropy are considerably larger in the exponential case with respect to a quadratic non-minimal coupling, reflecting the fact that the effective gravitational constant depends exponentially on the dynamics of the field.

description: We present a {\em Spitzer}-based mid-infrared study of a large sample of Blue Compact Dwarf galaxies (BCD) using the Infrared Spectrograph (IRS), including the first mid-IR spectrum of IZw18, the archetype for the BCD class and among the most metal poor galaxies known. We show the spectra of Polycyclic Aromatic Hydrocarbon (PAH) emission in low-metallicity environment. We find that the equivalent widths (EW) of PAHs at 6.2, 7.7, 8.6 and 11.2 $μ$m are generally weaker in BCDs than in typical starburst galaxies and that the fine structure line ratio, [NeIII]/[NeII], has a weak anti-correlation with the PAH EW. A much stronger anti-correlation is shown between the PAH EW and the product of the [NeIII]/[NeII] ratio and the UV luminosity density divided by the metallicity. We conclude that PAH EW in metal-poor high-excitation environments is determined by a combination of PAH formation and destruction effects.

description: During the food crisis in 2007/2008 the government of Serbia restricted the export of wheat to ensure that wheat supply on the domestic market is sufficient thereby dampening the increase in consumer food prices. This study investigates the effects of the export restriction on the integration, equilibrium and stability of its domestic wheat market. Within the framework of a Markov-switching error correction model, we utilize weekly wheat grower prices of Serbia and world market prices and compare the state of the wheat market prevailing in the time period before the crisis to when the exports controls are effective. Our results suggest that although the degree of market integration and thus the long-run price elasticity do not change during the crisis, the market equilibrium was disrupted and the stability was reduced during the crisis. Also, we find that the price dampening effect of the export restrictions prevailed only in a short time period and that the Serbian wheat grower prices even increased beyond the world market afterwards.
Quantum transport properties of two-dimensional systems in disordered magnetic fields with a fixed sign

description: Quantum transport in disordered magnetic fields is investigated numerically in two-dimensional systems. In particular, the case where the mean and the fluctuation of disordered magnetic fields are of the same order is considered. It is found that in the limit of weak disorder the conductivity exhibits a qualitatively different behavior from that in the conventional random magnetic fields with zero mean. The conductivity is estimated by the equation of motion method and by the two-terminal Landauer formula. It is demonstrated that the conductance stays on the order of $e^2/h$ even in the weak disorder limit. The present behavior can be interpreted in terms of the Drude formula. The Shubnikov-de Haas oscillation is also observed in the weak disorder regime.

description: Development of strong and competitive sector of small and medium enterprises has very important role in process of total transition in Republic of Serbia. This sector should be one of the guidelines of economical development in the future, like in developed countries. Within the ²Strategy of development of SME and entrepreneurship in Republic of Serbia from 2003 to 2008² government of the Republic of Serbia, not accidentally, placed, among many other sectors (which are expected to contribute and boost economical development, increase the employment rate, and realize increased foreign export earnings), the sector of agricultural products processing. It can be concluded that significant contribution from agriculture to improvement of overall economic status is expected. Accession to EU should be considered not only as the opportunity, but also as a serious task in agriculture restructuring. However, aggravating circumstance, in regard to export of agricultural and food products, first of all to EU countries, is the fact that this market is under strict protective measures within the policy of agriculture and measures of agrarian protectionism. In such conditions, it is very difficult for producers and food processors to enter such closed markets. Considering the flexibility of small and medium enterprises with regard to production programs, as well as their capability to adjust to economical trends, it can be expected that they become one of the most important subjects of support of agribusiness development in Republic of Serbia.

description: We study the evolution of chromospheric line and continuum emission during the impulsive phase of the X-class SOL2014-09-10T17:45 solar flare. We extend previous analyses of this flare to multiple chromospheric lines of Fe I, Fe II, Mg II, C I, and Si II, observed with IRIS, combined with radiative-hydrodynamical (RHD) modeling. For multiple flaring kernels, the lines all show a rapidly evolving double-component structure: an enhanced, emission component at rest, and a broad, highly red-shifted component of comparable intensity. The red-shifted components migrate from 25-50 km s$^{-1}$ towards the rest wavelength within $\sim$30 seconds. Using Fermi hard X-ray observations, we derive the parameters of an accelerated electron beam impacting the dense chromosphere, using them to drive a RHD simulation with the RADYN code. As in Kowalski et al. 2017a, our simulations show that the most energetic electrons penetrate into the deep chromosphere, heating it to T$\sim$10,000 K, while the bulk of the electrons dissipate their energy higher, driving an explosive evaporation, and its counterpart condensation -- a very dense (n$_e \sim 2 \times 10^{14}$ cm$^{-3}$), thin layer (30--40 km thickness), heated to 8--12,000 K, moving towards the stationary chromosphere at up to 50 km s$^{-1}$. The synthetic Fe II 2814.45A profiles closely resemble the observational data, including a continuum enhancement, and both a stationary and a highly red-shifted component, rapidly moving towards the rest wavelength. Importantly, the absolute continuum intensity, ratio of component intensities, relative time of appearance, and red-shift amplitude, are sensitive to the model input parameters, showing great potential as diagnostics.

description: During the period 2006-2007 diagnostics were conducted on territorial aspects of rural Lithuania with a special focus on the rural areas lagging behind. The study includes analysis of economic, demographic and social indicators of rural areas at a disaggregated level and a methodology enabling the assessment of opportunities and constraints and the comparisons of rural areas in various territories. The study objective is an improved set of diagnostics that captures territorial differences, improves the targeting of RDP measures and strengthens the framework for allocation and access to structural and rural development funds. The paper discusses diagnostic methods by reviewing concepts of rurality and presenting methods used for identifying and ranking leading and lagging territories. We use selected socio-economic indicators to describe differences among municipalities in Lithuania and identify the key factors that indicate more and less successful areas. These are then used to identify and rank leading and lagging municipalities with a development index.

description: Surprising asymmetry in the local electromechanical response across a single antiparallel ferroelectric domain wall is reported. Piezoelectric force microscopy is used to investigate both the in-plane and out-of- plane electromechanical signals around domain walls in congruent and near-stoichiometric lithium niobate. The observed asymmetry is shown to have a strong correlation to crystal stoichiometry, suggesting defect-domain wall interactions. A defect-dipole model is proposed. Finite element method is used to simulate the electromechanical processes at the wall and reconstruct the images. For the near-stoichiometric composition, good agreement is found in both form and magnitude. Some discrepancy remains between the experimental and modeling widths of the imaged effects across a wall. This is analyzed from the perspective of possible electrostatic contributions to the imaging process, as well as local changes in the material properties in the vicinity of the wall.
Exploring the $Λ$-deuteron interaction via correlations in heavy-ion collisions

description: $Λ$-deuteron two-particle momentum correlation functions, to be measured in high-energy heavy-ion collisions, are investigated. In particular, the question is addressed whether such correlations can serve as an additional and alternative source of information on the elementary $ΛN$ interaction. The study is performed within the Lednicky-Lyuboshits formalism, utilizing an effective range expansion for the two relevant $S$-wave $Λd$ amplitudes with parameters taken from the literature. It is found that in collisions characterized by a large emitting source the $Λd$ correlation function is predominatly sensitive to the quartet state ($^4S_{3/2}$). In contrast, for small source sizes the contribution from the doublet partial wave ($^2S_{1/2}$) could be significant. Though the latter is constrained by the hypertriton binding energy, its present experimental uncertainty impedes an accurate determination of the doublet amplitude and, in turn, complicates conclusions on the quartet state.

description: We study glued tensor and free products of compact matrix quantum groups with cyclic groups -- so-called tensor and free complexifications. We characterize them by studying their representation categories and algebraic relations. In addition, we generalize the concepts of global colourization and alternating colourings from easy quantum groups to arbitrary compact matrix quantum groups. Those concepts are closely related to tensor and free complexification procedures. Finally, we also study a more general procedure of gluing and ungluing.

description: Many farmers, in addition to normal farming activities, have already turned to agritourism as a source of additional farm income and opportunities. There are numerous benefits to be gained from the development of agritourism: it may strengthen local economy, create job opportunities and develop and promote training and certification programs to introduce young people to agriculture and the environment. Agritourism helps preserve rural lifestyles and landscape and offers the opportunity to provide "sustainable" tourism. Organic agriculture is due to demand for healthy foods with a high quality standard and limited use of chemical substances. Organic agriculture is closely connected to agritourism and tourism. The purpose of this paper is to identify and examine those factors that have helped rural communities to successfully develop agritourism, in particular organic-agritourism, and to discuss its entrepreneurship opportunities. Several focus groups were conducted with local business people and leaders regarding an applicative case of Southern Italy.

description: In the context of the present world economical crisis, the pre-accession and structural funds assigned by the European Union (which have been and still are high for Romania) can represent an important financial support for ensuring the sources of sustaining the investments meant to contribute to increase the living standard in rural areas, in the case of acceding countries and for member states that joined in 2004 and 2007. Still, for countries it is important to have a high level of acceding these funds, because history proved that few countries absorbed the whole amount of money from the pre-accession funds (Czech Republic is a positive example in this context) and the structural funds (Spain and Portugal are positive examples in this context). An important factor in accessing European funds is represented by the structures of consultancy (public and private) that may advise the potential beneficiaries of these funds, for both elaborating the projects of investments and their implementation.

description: Territory and natural conditions in Macedonia are well known in the World market of high quality production of oriental type of tobacco. Production of oriental tobacco at such a small territory is insignificant towards other producers (Bulgaria, Turkey), buy it is very important for Macedonian economy. The high value of exported tobacco and other tobacco products is regularly above 100 million USD (113 million USD for 2006 and 106 million USD for 2007). As a family production with low grade of mechanized labor processes, it provides survival of more than 100 000 residents of Macedonia. These reasons are enough to evaluate the importance of tobacco for a country with a gross national income per capita of around $4,120 in 2008, (GNI, Atlas method) and high unemployment rate (over 35%). Natural resources for oriental tobacco production are relatively adequate for the most of the countries from Mediterranean region as well as Balkan Peninsula. However, the specific climate and soil conditions in Macedonia have a high comparative value for oriental tobacco. They enabled the tobacco to have definite value above all other crops from Macedonia, especially in areas limited with water resources and soil with low percentage of humus. High level of tobacco production in the previous period has resulted with building of many huge industrial capacities, warehouses for final processing as well as three factories for cigarette production. They have been all build for the great domestic market (for over twenty million people of Former Yugoslav Republic) and partly for export. Nowadays, these capacities insufficiently are used with annual production of over 5,500 t of cigarettes. Because of inadequate agrarian policy, tobacco production stagnates in the period of long transition and shows a high instability through the years. Therefore, the advantages of Macedonian region remain inadequately used. Macedonian region is characterized with arid climate, because the annual rainfalls are 742 mm/m² (average of 25 years), and the average of the last 10 years is only 582 mm/m² (schedule of the rainfalls is quite unfavorable). The biggest part of the oriental tobacco production is designed for export to the most famous markets (EU, USA, Japan, etc.), because the unprocessed tobacco has a high quality. Specific physical-chemical characteristics make Macedonian tobacco a component of the blend used for large number of the World’s famous tobacco brands of cigarettes. Considering as competitive product in the World market, many countries are interested in buying Macedonian tobacco (EU, SAD, Japan etc.).
