description: Studies of fertilizer use in sub-Saharan Africa have been dominated by analyses of economic and market factors having to do with infrastructure, institutions, and incentives that prevent or foster increased fertilizer demand, largely ignoring how soil fertility status conditions farmer demand for fertilizer. We apply a switching regression model to data from 260 farm households in western Kenya in order to allow for the possibility of discontinuities in fertilizer demand based on a soil carbon content (SCC) threshold. We find that the usual factors reflecting liquidity and quasi-fixed inputs are important on high-SCC plots but not on those with poorer soils. External inputs become less effective on soils with low SCC, hence the discernible shift in behaviors across soil quality regimes. For many farmers, improved fertilizer market conditions alone may be insufficient to stimulate increased fertilizer use without complementary improvements in the biophysical conditions that affect conditional factor demand.

description: Spatially resolved photoluminescence of modulation doped AlGaAs/GaAs heterojunction was investigated in a sample of Corbino disk geometry subject to strong perpendicular magnetic fields. Significant spatial modulation of the photoluminescence was observed in form of one or more concentric rings which travelled across the sample when the magnetic field strength was varied. A topology of the observed structure excludes the possibility of being a trace of an external current. The effect is attributed to formation of compressible and incompressible stripes in a 2DEG density gradient across the sample.

description: Human resources management is one of the management functions, dealing with people as the essential resource of the organization. This function aims at the most efficient usage of employees in order to realize both organizational and individual goals. Nowadays high significance is attributed to human resources management, since the human factor is the resource that determines the success of an organization. The results of a company are in proportion with the knowledge and talent of the people on its payroll. Human talent and knowledge can be utilized to the greatest extent in case management is able to motivate employees to meet not only the necessary requirements but also to achieve the highest possible results. Human resources management consists of several fields of activities, among which the following are the most important: analysis, planning and assessment of the scope of activities, human resources planning, workforce supply, performance assessment, motivation, developing human resources, labour relations, labour safety, HEM information system. Our studies cover a few fields within human resources management. Our research has been carried out at organizations in Hajdú-Bihar County. The study is based on questionnaires, which have been processed by computers and evaluated using statistical methods.

Tri-bimaximal neutrino mixing from discrete subgroups of SU(3) and SO(3) family symmetry

description: It has recently been shown how tri-bimaximal neutrino mixing can be achieved, using the see-saw mechanism with constrained sequential dominance, through the vacuum alignment of a broken non-Abelian gauged family symmetry such as SO(3) or SU(3). Generalising the approach of Altarelli and Feruglio developed for an $A_4$ model we show how the reduction of the underlying symmetry to a discrete subgroup of SO(3) or SU(3) renders this alignment a generic property of such models. This means near tri-bimaximal mixing can be quite naturally accommodated in a complete unified theory of quark and lepton masses.

description: We investigate the helium dimer in strong magnetic fields, focusing on the spectrum of low-lying electronic states and their dissociation curves, at the full configuration-interaction level of theory. To address the loss of cylindrical symmetry and angular momentum as a good quantum number for nontrivial angles between the bond axis and magnetic field, we introduce the almost quantized angular momentum (AQAM) and show that it provides useful information about states in arbitrary orientations. In general, strong magnetic fields dramatically rearrange the spectrum, with the orbital Zeeman effect bringing down states of higher angular momentum below the states with pure $σ$ character as the field strength increases. In addition, the spin Zeeman effect pushes triplet states below the lowest singlet; in particular, a field of one atomic unit is strong enough to push a quintet state below the triplets. In general, the angle between the bond axis and the magnetic field also continuously modulates the degree of $σ$, $π$, and $δ$ character of bonds and the previously identified perpendicular paramagnetic bonding mechanism is found to be common among excited states. Electronic states with preferred skew field orientations are identified and rationalized in terms of permanent and induced electronic currents.

description: The paper investigates the effects of the institutional determinants on trade in agricultural and food products among the OECD countries using a gravity model approach. We focus on the impact of the quality of governance and the similarity of institutions in explaining variation in bilateral agricultural and food trade patterns. Results confirmed the separate effects for the institutional similarity and the institutional quality on trade patterns. The institutional similarity has positive and significant impact on trade in a similar institutional framework for agricultural, but less for food products. The institutional quality has significant positive impact on trade in both agricultural and food products for importing countries.

description: Black hole spectroscopy with gravitational waves is an important tool to measure the mass and spin of astrophysical black holes and to test their Kerr nature. Next-generation ground- and space-based detectors will observe binary black hole mergers with large signal-to-noise ratios and perform spectroscopy routinely. It was recently shown that small perturbations due, e.g., to environmental effects (the "flea") to the effective potential governing gravitational-wave generation and propagation in black hole exteriors (the "elephant") can lead to arbitrarily large changes in the black hole's quasinormal spectrum, including the fundamental mode, which is expected to dominate the observed signal. This raises an important question: is the black hole spectroscopy program robust against perturbations? We clarify the physical behavior of time-domain signals under small perturbations in the potential, and we show that changes in the amplitude of the fundamental mode in the prompt ringdown signal are parametrically small. This implies that the fundamental quasinormal mode extracted from the observable time-domain signal is stable against small perturbations. The stability of overtones deserves further investigation.

description: By applying precision nutrition the yield heterogeneity owing to the different features of soil spots can be taken into consideration. The planned and sprayed fertilizer adjusted to the expected yield rendered to soil spots can reduce the negative effects of artificial chemicals on soil and environment. The aim of this paper is to examine how the quantity and the cost of fertilizer (material and operational) will change on spot level on a certain plot during a five-year period, considering crop rotation, too. The following crops are in the rotation: winter wheat, corn and sunflower. Precision nutrition can be used in all the cultures mentioned above. Our earlier (static) model calculations have revealed that the threshold price of precision production was lower by 31% than in conventional technology. So it is necessary to explore for a longer period how the profitability of precision nutrition reacts to the changes in input and yield prices in different crops. The risk receptivity of precision nutrition can be characterized with the help of price sensitive analyses. Effects on profitability of other technological elements are not analysed in this paper.

description: CI/CD pipelines are in the middle of software development since they orchestrated several programmatic steps by enhancing their efficiency. This work focuses on the CI/CD pipeline management in cloud environments with focus on cloud constructs especially using Amazon Web Service for cloud infrastructure automation. This research initiates by creating a local software project and involves connecting to the cloud version control system, (Bitbucket). This pipeline is going to have an instantaneous response towards code changes, and is going to test using Pytest afterwards, before transferring the code within a containerized context using Docker, which will run on AWS EC2. This work compares AWS with GCP on other parameters such as deployment time, rollback time, scalability, cost and reliability. The findings indicate that AWS offers superior performance to GCP by providing a robust and Table CI/CD platform, required by companies that incorporate agile software development strategies.
The Holomorphic Tension of Vortices

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

description: We study the tension of vortices in N=2 SQCD broken to N=1 by a superpotential W(Φ), in color-flavor locked vacua. The tension can be written as T = T_{BPS} + T_{non BPS}. The BPS tension is equal to 4π|\T| where we call \T the holomorphic tension. This is directly related to the central charge of the supersymmetry algebra. Using the tools of the Cachazo-Douglas-Seiberg-Witten solution we compute the holomorphic tension as a holomorphic function of the couplings, the mass and the dynamical scale: \T = \sqrt{W'^2+f}. A first approximation is given using the generalized Konishi anomaly in the semiclassical limit. The full quantum corrections are computed in the strong coupling regime using the factorization equations that relate the N=2 curve to the N=1 curve. Finally we study the limit in which the non-BPS contribution can be neglected because small with respect to the BPS one. In the case of linear superpotential the non-BPS contribution vanishes exactly and the holomorphic tension gets no quantum corrections.

Towards Higgs masses and decay widths satisfying the symmetries in the (N)MSSM
Creators: name: Domingo, Florian

Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In models with an extended Higgs sector, such as the (N)MSSM, scalar states mix with one another. Yet, the concept of Higgs mixing is problematic at the radiative level, since it introduces both a scheme and a gauge dependence. In particular, the definition of Higgs masses and decay amplitudes can be impaired by the presence of gauge-violating pieces of higher order. We discuss in depth the origin and magnitude of such effects and suggest two strategies preserving or restoring gauge invariance. In addition, the intuitive concept of mixing and the simplicity of its definition in terms of two-point diagrams can make it tempting to include higher-order corrections on this side of the calculation, irrespectively of the order achieved in vertex diagrams. Using the global $SU(2)_{\mathrm{L}}$-symmetry in the decoupling limit, we show that no improvement can be expected from such an approach at the level of the Higgs decays, but that, on the contrary, the higher-order terms may lead to numerically large spurious effects.

description: Quantum error correction requires decoders that are both accurate and efficient. To this end, union-find decoding has emerged as a promising candidate for error correction on the surface code. In this work, we benchmark a weighted variant of the union-find decoder on the toric code under circuit-level depolarizing noise. This variant preserves the almost-linear time complexity of the original while significantly increasing the performance in the fault-tolerance setting. In this noise model, weighting the union-find decoder increases the threshold from 0.38% to 0.62%, compared to an increase from 0.65% to 0.72% when weighting a matching decoder. Further assuming quantum non-demolition measurements, weighted union-find decoding achieves a threshold of 0.76% compared to the 0.90% threshold when matching. We additionally provide comparisons of timing as well as low error rate behavior.

Neurodevelopmental characterization of semaphorin 5B in C57Black mice
Creators: name: Lett, Robyn Lynn Mwuese
Publisher: name: University of British Columbia
Year: 2009

description: The mammalian nervous system develops through five recognized stages: induction, differentiation, migration/axon guidance, synaptogenesis and pruning/apoptosis. Guidance cues, generally thought to be responsible for guiding axons through the developing organism, have been identified as playing additional roles in differentiation, directed cell migration, synaptogenesis, as well as pruning and apoptosis. Semaphorin 5B (Sema5B) is a member of the semaphorin family of guidance molecules; therefore, it is hypothesized that it is expressed in the developing nervous system of mice. This thesis has investigated the developmental expression pattern of Sema5B in C57Black mice by in situ hybridization, which demonstrated expression of Sema5B mRNA in four specific regions of focus: the spinal cord and associated dorsal root ganglia, the eye, the olfactory bulb and epithelium and the dorsal forebrain. In the spinal cord, Sema5B undergoes dynamic changes between E12 and E18 that are consistent with a potential role in the formation of laminar-specific targeting of sensory neurons within the dorsal horn. In the eye, expression of Sema5B is specific to the lens epithelium and the retinal ganglion cell (RGC) layer, which implies a role in either RGC differentiation, migration, or in the guidance of RGC axons to the optic disk. Expression of Sema5B by olfactory receptor neurons at E18 implies that expression may continue postnatally, thus indicating a potential role in the maintenance of the regenerative nature of the adult olfactory epithelium. Finally, expression of Sema5B in the ventricular zone and the cortical plate as it develops denotes a possible function of Sema5B in the differentiation and/or migration of neurons in the developing mouse forebrain.

description: Given a real number $x>0$, we determine $q_s(x):=\inf\mathscr{U}(x)$, where $\mathscr{U}(x)$ is the set of all bases $q\in(1,2]$ for which $x$ has a unique expansion of $0$'s and $1$'s. We give an explicit description of $q_s(x)$ for several regions of $x$-values. For others, we present an efficient algorithm to determine $q_s(x)$ and the lexicographically smallest unique expansion of $x$. We show that the infimum is attained for almost all $x$, but there is also a set of points of positive Hausdorff dimension for which the infimum is proper. In addition, we show that the function $q_s$ is right-continuous with left-hand limits and no downward jumps, and characterize the points of discontinuity of $q_s$. A large part of the paper is devoted to the level sets $L(q):=\{x>0:q_s(x)=q\}$. We show that $L(q)$ is finite for almost every $q$, but there are also infinitely many infinite level sets. In particular, for the Komornik-Loreti constant $q_{KL}=\min\mathscr{U}(1)\approx 1.787$ we prove that $L(q_{KL})$ has both infinitely many left- and infinitely many right accumulation points.

description: Creep of directionally solidified Sn-3Ag-0.5Cu wt.% (SAC305) samples with near-<110> orientation along the loading direction and different microstructural lengthscale is investigated under constant load tensile testing and at a range of temperatures. The creep performance improves by refining the microstructure, i.e. the decrease in secondary dendrite arm spacing (λ2), eutectic intermetallic spacing (λe) and intermetallic compound (IMC) size, indicating as a longer creep lifetime, lower creep strain rate, change in activation energy (Q) and increase in ductility and homogeneity in macro- and micro-structural deformation of the samples. The dominating creep mechanism is obstacle-controlled dislocation creep at room temperature and transits to lattice-associated vacancy diffusion creep at elevated temperature (T/T_M > 0.7 to 0.75). The deformation mechanisms are investigated using electron backscatter diffraction (EBSD) and strain heterogeneity is identified between b/-Sn in dendrites and b/-Sn in eutectic regions containing Ag3Sn and Cu6Sn5 particles. The size of the recrystallised grains is modulated by the dendritic and eutectic spacings, however, the recrystalised grains in the eutectic regions for coarse-scaled samples (largest λ2 and λe) is only localised next to IMCs without growth in size.

description: The coordination plays central role in the economics. The conventional economic theory looks at the market and enterprise (or hierarchy) as two different, separated manner of coordination of economic goods and services. However the modern organization theory, price theory and institutional economics show that different types (not only market and enterprise, but also several types of hybrid forms) of coordination (or governance structure) necessarily live together in the current economic system. Based on my previous research on the field of regional clusters in the food industry I came to the conclusion that the cluster is one of the spheres where economic coordination can occur. At the same time I pointed out that the ways of coordination can be ordered on an ordinary scale according to its normative or positive nature. I’ve also found that the choice between the coordination spheres (market, enterprise or cluster) is not arbitrary, but instead depends on the interest’s dimension which is represented by the exchange of goods and services in question.

description: The regulation of luminal ion concentrations is critical for the function of, and transport between intracellular organelles. The importance of the acidic pH in the compartments of the endosomal-lysosomal pathway has been well-known for decades. Besides the V-ATPase, which pumps protons into their lumen, a variety of ion transporters and channels is involved in the regulation of the organelles' complex ion homeostasis. Amongst these are the intracellular members of the CLC family, ClC-3 through ClC-7. They localize to distinct but overlapping compartments of the endosomal-lysosomal pathway, partially with tissue-specific expression. Functioning as 2Cl−/H+ exchangers, they can support the vesicular acidification and accumulate luminal Cl−. Mutations in the encoding genes in patients and mouse models underlie severe phenotypes including kidney stones with CLCN5 and osteopetrosis or hypopigmentation with CLCN7. Dysfunction of those intracellular CLCs that are expressed in neurons lead to neuronal defects. Loss of endosomal ClC-3, which heteromerizes with ClC-4, results in neurodegeneration. Mutations in ClC-4 are associated with epileptic encephalopathy and intellectual disability. Mice lacking the late endosomal ClC-6 develop a lysosomal storage disease with reduced pain sensitivity. Human gene variants have been associated with epilepsy, and a gain-of-function mutation causes early-onset neurodegeneration. Dysfunction of the lysosomal ClC-7 leads to a lysosomal storage disease and neurodegeneration in mice and humans. Reduced luminal chloride, as well as altered calcium regulation, has been associated with lysosomal storage diseases in general. This review discusses the properties of endosomal and lysosomal Cl−/H+ exchange by CLCs and how various alterations of ion transport by CLCs impact organellar ion homeostasis and function in neurodegenerative disorders.

description: The knowledge-based, competitive economy places a great emphasis on the education system. The responsibility of higher education is to impart knowledge of high standard which is in harmony with the continuously changing environment. Higher education has a special role in the knowledge-based economy since it does not only have to fulfill educational but also research an innovation tasks. The decrease in the traditional role of agriculture as well as international tendencies facilitate diversification, i.e. the emergence of new roles and the relevant activities. Due to the diversification of agriculture fields like environmental protection, bioenergetics, and rural development have become more emphatic. The growing importance of these new fields is also significant from the point of view of education. Well trained professionals are of vital importance for the agriculture. A significant number of fresh graduates are not employed in their profession; they find a job in other areas or continue their education in a different field of interest. This research is based on a representative survey amongst agricultural graduates. Its objective is finding facts about how the graduates of the past five years assess higher education training and also about the factors employers take into consideration when employing a fresh graduate.

description: Recruitment and hiring of new graduate nurses is seen as a potential strategy to mitigate the problem of nurse shortage. However, previous studies disclosed that new graduate nurses are inadequately prepared to enter practice and experience transition difficulties. This study aimed to determine the perceived competence and transition experience of new graduate Filipino nurses. Seventy-nine conveniently chosen new graduate nurses were surveyed in this descriptive cross-sectional research. Self-administered instruments were used to gather data. Descriptive statistics, Mann–Whitney U test, and Kruskal–Wallis test were the statistical tools employed. Results indicated that new graduate nurses had a high level of self-reported fundamental nursing skills (M= 7.99) and core competence (M= 8.16), although areas needing improvement were identified. There were no significant differences in the perceived competence based on the length of experience, year graduated, area of assignment, sex, type of school graduated, CPD participation, and hospital bed capacity (p> .05). The major difficulty experienced by new graduates during their transition was related to changes in role expectations (72.2%). Majority expressed the need for increased support during their transition (83.5%). The most satisfying aspects of their working environment were ongoing learning (81%) and peer support (74.7%), while the least satisfying was the negative nursing work environment (55.7%). New graduate nurses are equipped with the necessary nursing skills and core competencies. However, there are still gaps and areas needing improvement that should be addressed and supported to assist them in their transition to the world of professional nursing practice. Follow up, feedback, mentoring, and preceptorship are beneficial to enhance the competencies of new graduate nurses and facilitate their successful transition into the nursing workforce.

In the education system it’s not easy to measure the output of the services. The situation is more complicated if an organisation or a sector has multiple inputs and outputs. In this case a possible method of determining efficiency is Data Envelopment Analysis. In my paper I’d like to introduce this method and use it to compare the efficiency of higher education systems. Furthermore I am examining whether their efficiency is influenced by the extent of the contribution of the state and the private sector or socio-economic factors like GDP per capita and education level of parents.

description: We analyze the frequency dependence of shot noise in a spin filter consisting of a normal grain and ferromagnetic electrodes separated by tunnel barriers. The source of frequency-dependent noise is random spin-flip electron scattering that results from spin-orbit interaction and magnetic impurities. Though the latter mechanism does not contribute to the average current, it contributes to the noise and leads to its dispersion at frequencies of the order of the Korringa relaxation rate. Under nonequilibrium conditions, this rate is proportional to the applied bias $V$, but parametrically smaller than $eV/\hbar$.

description: Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum electrodynamics and in classical electric-circuit networks, we study flat bands and band-touching phenomena in such lattices. We analyze noninteracting nearest-neighbor hopping models on hyperbolic analogs of the kagome and dice lattices with heptagonal and octagonal symmetry. We show that two characteristic features of the energy spectrum of those models, namely the fraction of states in the flat band as well as the number of touching points between the flat band and the dispersive bands, can both be captured exactly by a combination of real-space topology arguments and a reciprocal-space description via the formalism of hyperbolic band theory. Furthermore, using real-space numerical diagonalization on finite lattices with periodic boundary conditions, we obtain new insights into higher-dimensional irreducible representations of the non-Euclidean (Fuchsian) translation group of hyperbolic lattices. First, we find that the fraction of states in the flat band is the same for Abelian and non-Abelian hyperbolic Bloch states. Second, we find that only Abelian states participate in the formation of touching points between the flat and dispersive bands.

description: Recently it has been found that quantum chromodynamics (QCD) phase diagram possesses a duality between chiral symmetry breaking and pion condensation. For the first time this was revealed in the QCD motivated toy model. Then it was demonstrated in effective models as well and new additional dualities being found. We briefly recap the main features of this story and then discuss its applications as a tool to explore the QCD phase structure. The most appealing application is the possibility of getting the results on the QCD phase diagram at large baryon density. Taking the idea from large $1/N_{c}$ universalities it was argued that the scenario of circumventing the sign problem with the help of dualities seems plausible. It is also discussed that there is a persistent problem about whether there should be catalysis or anti-catalysis of chiral symmetry breaking by chiral imbalance. One can probably say that the issue is settled after lattice results (first principle approach), where the catalysis was observed. But they used an unphysically large pion mass so it is still interesting to get additional indications that this is the case. It is shown just by the duality property that there exists catalysis of chiral symmetry breaking. So, having in mind our results and the earlier lattice simulations, one can probably claim that this issue is settled. It is demonstrated that the duality can be used to obtain new results. As an example, it is showcased how the phase structure of dense quark matter with chiral imbalance (with possibility of inhomogeneous phases) can be obtained from the knowledge of a QCD phase diagram with isopin asymmetry.

description: The requirements in terms of information availability, risk precaution and control in the food industry continue to increase. In this context the interest of companies in the Total Quality Management (TQM) approach is also increasing. This development attracts notice to Business Excellence and connected systems. Similarly, various quality management tools and techniques are available. In this regard a research project analyzed to what extent the companies in the food industry apply different activities of the TQM scheme. The research calculates the importance that the companies attach to different requirements of TQM and how they implement them. Additionally, statistical analysis provides evidence that there is a positive correlation between the implementation of the activities of TQM and the medium- to long-term success of a company. In this article the methodology and major findings of this research project are presented.

description: We obtain the bounds on arbitrary linear combinations of operators of dimension 6 in the Standard Model. We consider a set of 21 flavor and CP conserving operators. Each of our 21 operators is tightly constrained by the standard set of electroweak measurements. We perform a fit to all relevant precision electroweak data and include neutrino scattering experiments, atomic parity violation, W mass, LEP1, SLD, and LEP2 data. Our results provide an efficient way of obtaining bounds on weakly coupled extensions of the Standard Model.

description: Tourism is one of the leading sectors in the world economy. Enhancing its well-known economic, social and environmental benefits while managing its negative impacts are highly important for the national governments in European Union. Strategic planning is essential to meet the long term requirements of sustainability. National sustainable development strategies and tourism strategies are fundamental means of strategic planning as they provide guidance for the decision-makers of the tourism sector. The member states of the European Union have prepared their national sustainable development strategies, furthermore the Union’s common strategy and the national strategies of some member states have already been revised and renewed by now. The Hungarian strategies – National Sustainable Development Strategy and National Tourism Development Strategy – were completed the World Tourism Organization published its twelve aims for an agenda for sustainable tourism in 2005. Consequently these strategies are expected to contain references to the sustainability requirements and environmental, economic and socio-cultural aspects of tourism development. In the present study we analyse the issues of sustainable tourism development in the sustainable development strategies of the EU and Hungary and the National Tourism Development Strategy of Hungary 2005-2013 with special attention to the principles laid down by the WTO in 2005. Our aim is to investigate the cohesion between the principles of sustainable development and sustainable tourism, and their manifestations in some of the strategic documents influencing Hungarian tourism development.

description: In this paper, the design and analysis of coupled tank water level control system is done using robust
control theory. The main aim of this work is to improve level controlling mechanisms in industries and household
areas. In this paper, H ∞ and μ –synthesis controllers are designed to improve the level control system. The coupled
tank water level control system is designed using the proposed controller’s comparison and tested for tracking a
reference level signals (step, sine wave and random) and simulation results have been analyzed successfully. Finally
the comparative simulation results prove the effectiveness of the proposed coupled tank water level control system
with H ∞ controller for improving the tracking mechanism performance of the system.
