description: We explore the nature of orbits of stars moving in the meridional plane $(R,z)$ of an axially symmetric galactic model with a disk, a spherical nucleus, and a flat biaxial dark matter halo component. In particular, we study the influence of all the involved parameters of the dynamical system, by computing both the percentage of chaotic orbits and the percentages of orbits of the main regular resonant families in each case. To distinguish between ordered and chaotic motion, we use the smaller alignment index (SALI) method to extensive samples of orbits by numerically integrating the equations of motion as well as the variational equations. Moreover, a method based on the concept of spectral dynamics that utilizes the Fourier transform of the time series of each coordinate is used to identify the various families of regular orbits and also to recognize the secondary resonances that bifurcate from them. Two cases are studied for every parameter: (i) the case where the halo component is prolate and (ii) the case where an oblate dark halo is present. Our numerical investigation indicates that all the dynamical quantities affect, more or less, the overall orbital structure. It was observed that the mass of the nucleus, the halo flattening parameter, the scale length of the halo, the angular momentum, and the orbital energy are the most influential quantities, while the effect of all the other parameters is much weaker. It was also found that all the parameters corresponding to the disk only have a minor influence on the nature of orbits. Furthermore, some other quantities, such as the minimum distance to the origin, the horizontal, and the vertical force, were tested as potential chaos detectors. Our analysis revealed that only general information can be obtained from these quantities. We also compared our results with early related work.

description: This article explores the role of New Public Management (NPM) ideas in the reform of the Italian and Danish health systems. In particular, it investigates the arguments that have supported changes in their institutional and territorial dimensions. Whereas the institutional dimension is concerned with the allocation of authority between layers of government, the territorial dimension is related to the definition of the size of subnational governments. By adopting an argumentative approach to policy analysis and focusing on the role of ideas in policy formulation, the article shows how Italian and Danish policymakers have shaped the institutional and territorial changes that have taken place in their national health systems. Through document analysis and in-depth interviews with experts and decision-makers, we show that the relationship between changes in size and authority in relation to NPM ideas is not clear-cut. Whereas in Italy arguments about the need to change the allocation of authority were not tied to a discourse about the size of subnational governments and health agencies, in Denmark discourses about size and authority have run in parallel. The present study confirms previous findings and provides additional evidence suggesting that NPM ideas have spread widely through governments following a path of implementation that varies from one national context to another.
Increasing Impact of Federal Estate and Gift Taxes on the Farm Sector: Present Law and Proposed Changes

description: Up to the early 1960's, Federal estate and gift taxes were not large enough to present a major problem for owners of family-size farms. However, the average value of farm production assets increased from $47,500 per farm in 1962 to $102,100 in 1972. The estate tax exemption is $60,000, and an increasing number of heirs to farms are subject to the tax. Since 70 to 90 percent of total farm assets are in the form of fixed assets (land and buildings), heirs of farmers may have a liquidity problem in paying death taxes. While the Internal Revenue Code provides for the extension of payments in liquidity hardship cases, other code provisions create barriers to the use of this privilege. Changes currently mentioned for the Federal estate and gift tax laws include (1) unifying estate and gift taxes into a single transfer tax (gifts are now taxed at a lower rate); (2) taxing the appreciation of capital assets (capital gains) transferred at death; (3) changing the level of exemptions; (4) removing the 50-percent marital deduction; and (5) liberalizing tax payment rules in liquidity hardship cases.

description: Within the framework of the Kondo-Heisenberg model, we analyse the effect of charge fluctuation on the modulated spin liquid (MSL) and antiferromagnetic (AF) orders which were established in a previous publication. We discuss the emergence of two quantum critical lines separating the coexisting Kondo-MSL and Kondo-MSL-AF phases. The various order parameters of the system possess a characteristic signature observable on the electronic band structure of each of the phases. We calculate that the MSL order is indeed a possible explanation of the hidden order phase of $URu_{2}Si_{2}$ heavy fermion compound. Our model produces results in qualitative agreement with the experimental (T,P) phase diagram and the two gap openings in the system and quantitative agreement with the entropy and Sommerfeld coefficient evolution.

Publisher: name: Zenodo
Year: 2015

description: The idea of banks financing the private sector as an engine of economic growth has a long history. The long-held belief of positive relationship between credit financing and manufacture sector growth has prompted to be a principal component of policy advice in many developing countries. However, it is still an issue of high debate between developed and developing nations governments and policy makers. Nowadays, many empirical studies confirm the existence of strong and positive link between credit financing and economic growth in general and manufacturing sector in particular while few found significant negative relationship. Thus, the long-run and short-run impact of credit financing on manufacturing sector performance is analyzed using Johansson method of co-integration approach and Vector Autoregressive Model (VARM) based on annual data for the period 1974/75-2013/14. The results suggest the existence of significant positive impact and insignificant negative impact of trade credit financing on manufacturing sector growth in the long and short-run respectively. As a result, an evidence for strategic financing of infant domestic manufacturing industries meant to foster economic growth of the nation has been inferred.

description: Debris disks are thought to be sculptured by neighboring planets. The same is true for the Edgeworth-Kuiper debris disk, yet no direct observational evidence for signatures of giant planets in the Kuiper belt dust distribution has been found so far. Here we model the dust distribution in the outer solar system to reproduce the dust impact rates onto the dust detector onboard the New Horizons spacecraft measured so far and to predict the rates during the Neptune orbit traverse. To this end, we take a realistic distribution of transneptunian objects to launch a sufficient number of dust grains of different sizes and follow their orbits by including radiation pressure, Poynting-Robertson and stellar wind drag, as well as the perturbations of four giant planets. In a subsequent statistical analysis, we calculate number densities and lifetimes of the dust grains in order to simulate a collisional cascade. In contrast to the previous work, our model not only considers collisional elimination of particles, but also includes production of finer debris. We find that particles captured in the 3:2 resonance with Neptune build clumps that are not removed by collisions, because the depleting effect of collisions is counteracted by production of smaller fragments. Our model successfully reproduces the dust impact rates measured by New Horizons out to ~23AU and predicts an increase of the impact rate of about a factor of two or three around the Neptune orbit crossing. This result is robust with respect to the variation of the vaguely known number of dust-producing scattered disk objects, collisional outcomes, and the dust properties.

description: Yang-Mills theory as the foundation for quantum chromodynamics is a non-Abelian gauge theory with self-interactions between vector particles. Here, we study the Yang-Mills Hamiltonian with nonlinear color oscillations in the absence of external sources corresponding to the group $SU(2)$. In the quantum domain, we diagonalize the Hamiltonian using the optimized trigonometric basis expansion method and find accurate energy eigenvalues and eigenfunctions for one and two degrees of freedom. We also compare our results with the semiclassical solutions.

title: Das Negative in der Philosophie Eugen Finks
Creators: name: Coli, Anna Luiza
Publisher: name: Bergische Universität Wuppertal
Year: 2022

description: Die vorliegende Arbeit beabsichtigt einen Leseschlüssel zur Philosophie Eugen Finks aus dem Leitfaden des Negativen anzubieten. Die hier vertretene Auffassung geht von einer Beachtung seines philosophischen Projekts aus der Perspektive einer Autonomie und Originalität gegenüber Finks zeitgenössischen Philosophien – Edmund Husserl und Martin Heidegger. Das Ziel ist es, einen Kontrapunkt zu der immer noch vorherrschenden Tendenz, Finks hauptsächlich als Interpret sowohl von Husserl, als auch von Heidegger, in Betracht zu nehmen. Im Laufe der Arbeit wird deutlich, dass der direkte Dialog mit anderen Philosophien – u.a. mit Nietzsches, Kants und vor allem mit Hegels – das methodische Verfahren des Aufbaus seines eigenen Denkens darstellt. Das Negative ist wiederum ein besonderer Begriff, der nicht nur die beiden Momente von Finks Philosophie durchquert, sondern in dem die metaphysische Umgestaltung seines späteren Denkens, die jene beide Momente unterscheidet, am offensichtlichsten ist. Um diese zwei Momente in Finks Werk zu bezeichnen, verweisen wir hier auf eine meontische, den Assistentenjahren bei Husserl betreffende Denkmatrix einerseits, und andererseits auf eine kosmologische Denkmatrix, die sich als solche erst nach Husserls Tod entwickelte. Die Bewegung des Negativbegriffs offenbart sich am Ende als eine Entwicklung der finkschen eigenen Auffassung der Philosophie, welche sich im Übergang von dem Projekt einer meontischen Phänomenologie zum kosmologischen Projekt einer negativen Phänomenologie zusammenfassend darstellen lässt.
description: The present work intends to offer an interpretation key to Eugen Fink’s philosophy from the leitmotif of the negative. The approach taken here considers his philosophical project from a perspective of autonomy and originality regarding Fink’s contemporary philosophies – Edmund Husserl und Martin Heidegger. The aim is to provide a counterpoint to the still predominant tendency of considering Fink mainly as an interpret of both Husserl and Heidegger. In the course of the work it becomes clear that the direct dialogue with other philosophies – for instance with Nietzsche’s, Kant’s and above all Hegel’s philosophy – is the methodological procedure through which he raises his own philosophy. The negative accounts for a particular concept that not only traverses the two moments of Fink’s philosophy, but in which the metaphysical transformation of his later thinking is most manifest. In order to distinguish these moments in Fink’s work, we refer here on the one hand to a meontic matrix of thought, the one that prevailed during the period of assistance to Husserl, and on the other hand to a cosmological matrix of thought, which was developed as such only after Husserl’s death. The movement of the negative concept ultimately reveals itself as a development in Fink’s own conception of philosophy, which could be summarized by the transition from the early project of a meontic phenomenology to the late cosmological project of a negative phenomenology.

description: We have obtained the equilibrium volumes, bulk moduli, equations of state of the ferromagnetic cubic $α$ and paramagnetic hexagonal $ε$ phases of iron in close agreement with experiment using an ab initio dynamical mean-field theory approach. The local dynamical correlations are shown to be crucial for a successful description of the ground-state properties of paramagnetic $ε$-Fe. Moreover, they enhance the effective mass of the quasiparticles and reduce their lifetimes across the $α\to ε$ transition leading to a step-wise increase of the resistivity, as observed in experiment. The calculated magnitude of the jump is significantly underestimated, which points to non-local correlations. The implications of our results for the superconductivity and non-Fermi-liquid behavior of $ε$-Fe are discussed.

description: We propose a simple method for realizing a multiqubit phase gate of one qubit simultaneously controlling $n$ target qubits, by using three-level quantum systems (i.e., qutrits) coupled to a cavity or resonator. The gate can be implemented using one operational step and without need of classical pulses, and no photon is populated during the operation. Thus, the gate operation is greatly simplified and decoherence from the cavity decay is much reduced, when compared with the previous proposals. In addition, the operation time is independent of the number of qubits and no adjustment of the qutrit level spacings or the cavity frequency is needed during the operation.

description: Suicide prevention needs measures, and further understanding of the role of adverse childhood experiences may elucidate the suicide process and ease the identification of suicide risk. A random sample of adults, aged 18–28 years and representative of the general population living in Finland, participated in a nationwide health examination survey. Of them (n = 793) we analyzed whether severe or chronic disease in childhood before the age of 16 years contributed to suicidality (suicidal ideation and/or suicide attempts), and whether severe or chronic disease in childhood was associated with mental disorders, current psychological distress, current usage of prescription medicines, or current work capacity. Having severe or chronic disease in childhood contributed independently to suicidality, with the odds ratio of 5.41 (95% confidence interval of 2.98–9.82, p < .001), but the significance of this association was lost after controlling for mental disorders. Having severe or chronic disease during childhood, as compared not having such condition, was associated with having more frequently anxiety (p < .001), greater psychological distress (p < .001), more frequently usage of psychotropic medicines (p < .001), and poorer work capacity (p < .001). Having severe or chronic disease in childhood not only increased the odds for suicidality, but also associated with anxiety, current psychological distress, current usage of psychotropic medication, and current work capacity in young adulthood.

description: Schizophrenia with persistent negative symptoms (PNS) may have different characteristics regarding negative symptom dimensions and heritability patterns. This study aimed to investigate the dimensional characteristics of PNS and their relationships with schizotypal features in first-degree relatives (FDRs). The study included 142 patients, 142 FDRs, and 71 healthy controls (HC). Patients were evaluated with the Positive and Negative Symptom Scale (PANSS), Brief Negative Symptom Scale (BNSS), Calgary Depression Scale for Schizophrenia (CDSS), and Simpson-Angus Scale (SAS). Schizotypy Personality Questionnaire was applied to FDR and HC groups. Clinical symptoms were compared between primary-PNS, secondary-PNS, and non-PNS groups. In addition, schizotypy scores were compared between FDRs and HCs. Then, the relationship between the symptoms of the patients in the PNS group and the schizotypy scores of their relatives was evaluated by multiple regression analysis. All negative symptom dimension scores were similar in primary-PNS and secondary-PNS and lowest in non-PNS. PNS-FDR had higher in all schizotypy scores than non-PNS-FDR and HC, except for lack of close friends and social anxiety. In the PNS group, positive symptom severity and PANSS experiential deficit scores significantly predicted positive and negative schizotypy scores in relatives. Negative schizotypy was associated with asociality. The PNS is likely a subtype in which the genetic basis of negative symptoms is stronger and is associated with genetic abnormalities shared by positive and negative schizotypy dimensions in relatives. Family-based genetic studies will be beneficial in enlightening the genetic etiology of PNS.

description: Price spreads between retail and wholesale markets for beef and pork have shown several distinct increases over the past decade. Both consumers and producers have felt the "middleman" receives too large a share of the consumer's meat dollar. But little has been said concerning the longrun effects of the amount and form of the margin on production and prices. Three sets of alternative margin plans are examined by simulation. One compares the effects of a change in the form of the margin, from fixed to percentage. The two other plans involve changing the levels of the fixed and percentage margins. For each of these margin strategies, prices and production of beef and pork and the size of the domestic beef herd are compared with expected results under the current practices (the base projection) through 1985.

description: This letter addresses the issue of interfacial crack propagation mechanisms on various interfaces with using molecular dynamics. Four different interfacial crack propagation manners are recognized by MD simulations: 1, the crack propagates along the interface strictly; 2, the nucleation of a twinning at the crack tip leads to the crack tip blunting; 3, the daughter crack appears ahead of the main crack and then coalesces to the mother crack; 4, the crack tip blunts with stacking fault nucleation at the crack tip. Furthermore, the adhesive strength coefficient λis used to identify the type of the interface. Interface with λ> 0.9 means an ordered interface, and interfacial crack propagates in mode I or mode II. While λ< 0.9 represents a disordered interface, and mode III and mode IV of the interfacial cracks are preferred. This work illustrates the effect of adhesive strength of interface on the mechanism of crack propagation along the interface of metal/ceramics nano-composites.

description: Waste lubricant oil (WLO) is a critical environmental issue because of its recycle and disposal challenges. A potent biosurfactant-producing bacterial strain was isolated by the enrichment culture technique using WLO as the sole carbon source from the oil-contaminated soils. The strain was identified as Achromobacter xylosoxidans (NCBI GenBank accession number: MW673656) based on the morphological, biochemical, and 16S rRNA gene sequencing. The preliminary characterization of the produced biosurfactant by biochemical methods revealed its glycolipid nature. The strain possessed extensive biodegradative potential and degraded various components present in WLO. The gas chromatography-mass spectrometry (GC-MS) analysis showed that the strain could degrade hydrocarbons (C7-C22) and diethyl phthalate, a priority pollutant, with a relative degradation of 43.87% within 7 days of incubation. The biodegradation of WLO by the strain confers its use in the bioremediation of oil-polluted environments, and the simultaneous biosurfactant production is undoubtedly a step toward greener technology.

description: When a harmonic oscillator is under the influence of a Gaussian process such as linear damping, parametric gain, and linear coupling to a thermal environment, its coherent states are transformed into states with Gaussian Wigner function. Qubit states can be encoded in the |0> and |1> Fock states of a quantum harmonic oscillator, and it is relevant to know the fidelity of the output qubit state after a Gaussian process on the oscillator. In this paper we present a general expression for the average qubit fidelity in terms of the first and second moments of the output from input coherent states subjected to Gaussian processes.

description: A metastable perovskite BiFe0.5Sc0.5O3 synthesized under high-pressure (6 GPa) and high- temperature (1500 K) conditions was obtained in two different polymorphs, antipolar Pnma and polar Ima2, through an irreversible behaviour under a heating/cooling thermal cycling. The Ima2 phase represents an original type of a canted ferroelectric structure where Bi3+ cations exhibit both polar and antipolar displacements along the orthogonal [110]p and [1-10]p pseudocubic directions, respectively, and are combined with antiphase octahedral tilting about the polar axis. Both the Pnma and Ima2 structural modifications exhibit a long-range antiferromagnetic ordering with a weak-ferromagnetic component below TN ~ 220 K. Analysis of the coupling between the dipole, magnetic and elastic order parameters based on a general phenomenological approach revealed that the weak-ferromagnetism in both phases is mainly caused by the presence of the antiphase octahe- dral tilting whose axial nature directly represents the relevant part of Dzyaloshinskii vector. The magnetoelectric contribution to the spontaneous magnetization allowed in the polar Ima2 phase is described by a fifth-degree free-energy invariant and is expected to be small.

description: Cadmium (Cd) is a metal widely known to cause toxic effects on the environment and human health. Soil represents a rich habitat for fungi, which have certain characteristics in their cell wall that made them a powerful tool for biosorption of toxic metals. Therefore, it was sought to identify potential filamentous fungi for different methods of remediation of contaminated areas. The identification of fungi from agricultural cultivation areas that can tolerate Cd and help in cadmium remediation processes occurred through the isolation and culture of several microorganisms submitted to screening experiments and tolerance evaluation. Four strains of the genera Fusarium sp., Penicillium sp., and Aspergillus sp. were isolated. Those strains showed abilities to tolerate the stress caused by Cd, presenting a tolerance index (Ti) of 13.79 − 107.30%. Analyses of FTIR demonstrated the existence of different functional groups in the cell wall that can be involved in the coordination of Cd2+ ions, as C = O stretches of carboxyl and amide-I. Results showed a Cd uptake range of 0.88 − 3.61 mg Cd g−1 of dry biomass. The results indicated that Fusarium sp. and Penicillium sp. isolated from agricultural sites are highly tolerant to Cd and are promising fungi for implementation in remediation processes.

description: The need exists for new criteria to reflect the qualitative as well as quantitative aspects of market performance. Also emphasized in the report is the multidimensional nature of performance. The U.S. Department of Agriculture and the Marketing Science Institute jointly sponsored a project to evaluate current market performance concepts and measures and develop new or improved ones. At this point, industrial organization theory provides the only analytical framework of market performance that is well developed and empirically tested. The structure of markets and their performance have been found to be related—but not in a linear fashion. Vertical market relationships need further analysis to expand on the few existing insights into market performance. Empirical and theoretical work have focused mainly on horizontal relationships. This report brings together several recent efforts to expand conceptual models of vertical market systems. Two new measures are presented: The value of retail exchange services and an Index of Consumer Satisfaction. These attempt to overcome the lack of attention given by existing measures to the level and distribution of consumer satisfaction with goods and services. Given the numerous and changing dimensions of market performance, and the narrow focus of most performance measures, a multidimensional information system on market performance needs to be set up. Such a system could provide greater continuity among the uses of existing performance measures, assimilate the findings of individual studies, and act as a catalyst for further examination of the factors influencing market performance.

In particular, the mirror coreference biases displayed by stimulus-experiencer and experiencer-stimulus predicates have been considered strong evidence for this approach. We provide evidence for the Asymmetry Hypothesis, stating that I-Caus and I-Cons are derived from different mechanisms. While we also assume that I-Caus is driven by verb semantics, we contend that I-Cons follows from general discourse-structural principles. Evidence is provided by four production experiments in German investigating the coreference and coherence properties of the aforementioned verb classes in detail. Experiment 1 establishes that the classes mirror each other with respect to coreference biases. Experiments 2 and 3 show, however, that there is no such symmetry with regard to coherence biases. Finally, Experiment 4 provides fine-grained evidence for the underlying strategies for providing contingency specifications.

description: The numerical noise inherent to particle-in-cell simulation of 3D high intensity bunched beams is studied with the TRACEWIN code and compared with an analytical model by Struckmeier. The latter assumes that entropy growth can be related to Markov type stochastic processes due to temperature anisotropy and the artificial collisions caused by using macro-particles and calculating the space charge effect. The resulting noise can lead to growth of the six-dimensional rms emittance and a suitably defined rms entropy. We confirm the dependence of this growth on the bunch temperature anisotropy as predicted by Struckmeier. However,we also find an apparently modified mechanism of noise generation by the non-Liouvillean effect of the Poisson solver grid, which exists in periodic focusing systems even in the complete absence of temperature anisotropy. Our findings are applicable in particular to high current linac simulation, where they can provide guidance to estimate noise effects and help finding an effective balance between the number of simulation particles and the grid resolution.

title: Biobjective Shape Optimization Algorithms Enhanced by Derivative Information

description: A biobjective PDE constrained shape optimization problem where the reliability and the cost of a ceramic component is optimized simultaneously and for which gradient information is available is considered. The probability of failure of the component under tensile load is modeled via a probabilistic Weibull-type model, while it is assumed that the cost is proportional to the volume of the component. Three different classes of gradient-based biobjective optimization methods are suggested and compared at 2D test cases. For the numerical implementations a first discretize then optimize strategy is utilized. The implementations benefit from efficient gradient computations using adjoint equations. The first class of gradient-based optimization methods that are considered are biobjective decent methods, where a biobjective steepest descent algorithm and the weighted sum method are investigated. The results of these methods yield approximations of the Pareto fronts that nicely display the trade-off between reliability and cost and give rise to innovative shapes that compromise between these conflicting objectives. For the second class of methods a novel approach for the efficient and reliable approximation of the Pareto front of sufficiently smooth unconstrained biobjective optimization problems is suggested and compared with a predictor-corrector method from the literature. For the novel method optimality conditions of the weighted sum scalarizations are utilized to describe (parts of) the Pareto front as a parametric curve, parameterized by the scalarization parameter (i.e., the weight in the weighted sum scalarization). Its sensitivity w.r.t. parameter variations are described by an ordinary differential equation (ODE). Starting from an arbitrary initial Pareto optimal solution, e.g., a solution of the first class of methods, the Pareto front can then be traced by numerical integration. An error analysis based on Lipschitz properties is provided and an explicit Runge-Kutta method for the numerical solution of the ODE is suggested. This method is then validated on biobjective test functions and applied on the given biobjective shape optimization problem. The third class of gradient-based biobjective optimization methods are surrogate model based methods. In particular, „Efficient Global Optimization“ (EGO) is considered which utilizes a surrogate model that is constructed via Gaussian random fields and is a global optimization method. The Gaussian model is also called Kriging model. In this work, we also consider Gradient Enhanced Kriging (GEK) models where gradient information is incorporated in the Kriging model. We choose EGO with Kriging and GEK to compute benchmark solutions for the given biobjective shape optimization problem since EGO is commonly used in applications. These benchmark results are then compared with the results of the other classes of methods.

description: Nickel is a valuable metal that is becoming more prevalent in the industry. Column bioleaching was used in this study to extract nickel from magnesium-bearing sulfide minerals. Two different sulfidic samples with different nickel and magnesium content were utilized to investigate the performance of column bioleaching. It was discovered that mesophilic cultures’ adaptation is delayed by increasing magnesium contents. Bioleaching outperformed leaching in terms of recovery by 80% compared to 50% in sample 1 and 70% compared to 40% in sample 2. Jarosite is precipitated in samples with a high magnesium content due to the high pH and oxidation level, which lowers bioleaching effectiveness. The pretreatment method using acid washing before the start of bioleaching treatment can reduce the amount of magnesium in samples, which increases the Ni recovery in both samples. SEM analysis was performed on each bioleaching residue. The result showed that high amounts of magnesium in the second sample could be a factor in the precipitation of jarosite. Finally, it can be concluded that the pretreatment method is a feasible Bio-heap operation. Column bioleaching of nickel was tested by mix mesophile culture in two different samples. Bacteria were found to be less adaptable to magnesium-rich minerals. More than 95% of nickel was extracted from both samples. Acid washing was identified as the best pretreatment method for each sample.
PERFORMANCE EVALUATION OF CENTER PIVOT SPRINKLER IRRIGATION SYSTEM: CASE STUDY ON HIWOT AGRICULTURAL MECHANIZATION, ETHIOPIA

description: Performance evaluation of center pivot sprinkler irrigation system installed at Hiwot Agricultural Mechanization farm was conducted. The existing irrigation system and agricultural practices were studied and measurements of the water application uniformity indicators were made and performance gaps were identified. HAM farm has 32 center pivot machines, out of which only five center pivot machines were under operation at the time of the present study. Radial measurements of water application along the CP sprinkler irrigation system lateral line were made for the estimation of coefficient of uniformity, distribution uniformity, and potential application efficiency of low quarter. Catch cans were placed along the CP lateral at 3m spacing for collection of water application along the lateral of center pivot. The measurement were made at five location s identified by the number of CP irrigation machine, m4, m6, m7, m8, and m12. Three of the locations were at upstream (m8, m12, and m4) and two located in middle (m6 and m7) of HAM farm. The measurements at location m4 were made twice, day time (about 2 pm) and night time (about 9 p m), however, for the remaining locations measurements were made only during day time. The measured value of water application rate for different locations along center pivot lateral line varied widely, generally lower values at pivot and higher values at end of center pivot lateral line. The Distribution uniformity, coefficient of uniformity and potential application efficiency of low quarter were varied from 67% to 85%, 73% to 86%, and 66% to 80% respectively. The highest value of DU was at night time measurement for location m4 as compared with m4 at day time due to lower wind velocity during night time (1.5m/s) and lowest value was for location m7. The highest value of CU was at location m7 whereas the lowest value was for location m12. The application rate at all the location was higher as compared to basic infiltration.

description: In an eye-tracking-while-reading study, we investigated adult monolinguals' (N = 80) processing of two-clause sentences embedded in short narratives. Three principles theorised to guide comprehension of complex sentences were contrasted: one operating at the clause level, namely clause structure (main clause – subordinate clause or vice versa), and two operating at the discourse-level, namely givenness (given-new vs. new-given) and event order (chronological vs. reverse order). The results indicate that clause structure mainly affects early stages of processing, whereas the two principles operating at the discourse level are more important during later stages and for reading times of the entire sentence. Event order was found to operate relatively independently of the other principles. Givenness was found to overrule clause structure, a phenomenon that can be related to the grounding function of preposed subordinate clauses. We propose a new principle to reflect this interaction effect: the grounding principle.
Partially-PT-symmetric optical potentials with all-real spectra and soliton families in multi-dimensions

description: Multi-dimensional complex optical potentials with partial parity-time (PT) symmetry are proposed. The usual PT symmetry requires that the potential is invariant under complex conjugation and simultaneous reflection in all spatial directions. However, we show that if the potential is only partially PT-symmetric, i.e., it is invariant under complex conjugation and reflection in a single spatial direction, then it can also possess all-real spectra and continuous families of solitons. These results are established analytically and corroborated numerically.
