description: We describe topological edge solitons in a continuous dislocated Lieb array of helical waveguides. The linear Floquet spectrum of this structure is characterized by the presence of two topological gaps with edge states residing in them. A focusing nonlinearity enables families of topological edge solitons bifurcating from the linear edge states. Such solitons are localized both along and across the edge of the array. Due to the non-monotonic dependence of the propagation constant of the edge states on the Bloch momentum, one can construct topological edge solitons that either propagate in different directions along the same boundary or do not move. This allows us to study collisions of edge solitons moving in the opposite directions. Such solitons always interpenetrate each other without noticeable radiative losses; however, they exhibit a spatial shift that depends on the initial phase difference.

description: Conventional agriculture systems of production often lead to environmental degradation, economic problems and even social conflict. The efficacy of agriculture systems conducive to the economic, environmental and social sustain- ability of farming operations has been demonstrated, yet the adoption of sustainable agricultural practices is not widespread. This study evaluates the barriers of sustainable agriculture by wheat farmers in Takestan using a descriptive–correlation survey methodology. This quantitative study was based on a Researcher made questionnaire designed to elicit the barriers to adoption of sustainable agriculture practices perceived by a sample of 149 wheat farmers in the Takestan (N=268), through a stratified random sampling technique. Instrument validity was confirmed by a panel of experts. The reliability estimated by Cronbach’s coefficient (α=0.905). The data has been analyzed using the SPSS (16). The results revealed that the high cost of sustainable agriculture was the most important barriers in its implementation (M=4.74). The findings of multiple regressions explained that farmer’s attitudes and practices of sustainable agriculture explained 89 percent of the variance of the barriers of sustainable agriculture. Farmer’s attitudes had the most influence on the deter

description: In most real-world settings, due to limited time or other resources, an agent cannot perform all potentially useful deliberation and information gathering actions. This leads to the metareasoning problem of selecting such actions. Decision-theoretic methods for metareasoning have been studied in AI, but there are few theoretical results on the complexity of metareasoning. We derive hardness results for three settings which most real metareasoning systems would have to encompass as special cases. In the first, the agent has to decide how to allocate its deliberation time across anytime algorithms running on different problem instances. We show this to be $\mathcal{NP}$-complete. In the second, the agent has to (dynamically) allocate its deliberation or information gathering resources across multiple actions that it has to choose among. We show this to be $\mathcal{NP}$-hard even when evaluating each individual action is extremely simple. In the third, the agent has to (dynamically) choose a limited number of deliberation or information gathering actions to disambiguate the state of the world. We show that this is $\mathcal{NP}$-hard under a natural restriction, and $\mathcal{PSPACE}$-hard in general.

description: The main purpose of this study was to investigate the major barriers to application of Good Agricultural Practices (GAPs) technologies in sustainability of livestock by ranchers of Meshkinshahr. A sample of 120 farmers was selected by using proportional random sampling method. Data were collected by means of a questionnaire. Validity of questionnaire was determined through Agricultural Jihad exports of Meshkinshahr County and some faculty members at University of Tehran, Department of Agricultural Management and Development. Cronbach’s alpha was used to estimate the reliability. The reliability was found to be acceptable. The results of Factor Analysis showed that infrastructure barriers, informational- educational barriers, institutional-support barriers, personal barriers, economical barriers were the five barriers to application of Good Agricultural Practices (GAPs) technologies in livestock unites. These factors explained 67.23 percent of the total variance.

description: We consider a nonlinear semi-classical Schroedinger equation for which quadratic oscillations lead to focusing at one point, described by a nonlinear scattering operator. The relevance of the nonlinearity was discussed by R. Carles, C. Fermanian-Kammerer and I. Gallagher for $L^2$-supercritical power-like nonlinearities and more general initial data. The present results concern the $L^2$-critical case, in space dimensions 1 and 2; we describe the set of non-linearizable data, which is larger, due to the scaling. As an application, we precise a result by F. Merle and L. Vega concerning finite time blow up for the critical Schroedinger equation. The proof relies on linear and nonlinear profile decompositions.

description: We theoretically demonstrate that the second-order topological insulator with robust corner states can be realized in two-dimensional $\mathbb{Z}_2$ topological insulators by applying an in-plane Zeeman field. Zeeman field breaks the time-reversal symmetry and thus destroys the $\mathbb{Z}_2$ topological phase. Nevertheless, it respects some crystalline symmetries and thus can protect the higher-order topological phase. By taking the Kane-Mele model as a concrete example, we find that spin-helical edge states along zigzag boundaries are gapped out by Zeeman field whereas in-gap corner state at the intersection between two zigzag edges arises, which is independent on the field orientation. We further show that the corner states are robust against the out-of-plane Zeeman field, staggered sublattice potentials, Rashba spin-orbit coupling, and the buckling of honeycomb lattices, making them experimentally feasible. Similar behaviors can also be found in the well-known Bernevig-Hughes-Zhang model.

The sub-milliarcsecond radio structure of this source has been studied with dual-frequency (1.6 and 5 GHz), polarization-sensitive VSOP observations during 2001 and 2002. Here we present the results of this monitoring campaign. At the time of these observations, the source was weakly polarized and characterized by a radio core that is clearly resolved on space-ground baselines.

description: This paper aims to connect the theory of relativistic cosmology number counts with the astronomical data, practice, and theory behind the galaxy luminosity function (LF). We treat galaxies as the building blocks of the Universe, but ignore most aspects of their internal structures by considering them as point sources. However, we do consider general morphological types in order to use data from galaxy redshift surveys, where some kind of morphological classification is adopted. We start with a general relativistic treatment for a general spacetime, and then link the derived expressions with the LF definition adopted in observational cosmology. Then equations for differential number counts, the related relativistic density per source, and observed and total relativistic energy densities of the universe, and other related quantities are written in terms of the luminosity and selection functions. As an example of how these theoretical/observational relationships can be used, we apply them to test the LF parameters determined from the CNOC2 galaxy redshift survey, for consistency with the Einstein-de Sitter (EdS) cosmology, which they assume, for intermediate redshifts. We conclude that there is a general consistency for the tests we carried out, namely both the observed relativistic mass-energy density, and the observed relativistic mass-energy density per source, which is equivalent to differential number counts, in an EdS Universe. In addition, we find clear evidence of a large amount of hidden mass, as has been obvious from many earlier investigations. At the same time, we find that the CNOC2 LF give differential galaxy counts somewhat above the EdS predictions, indicating that this survey observes more galaxies at 0.1 < z < 0.4 than the model's predictions.

description: Winds driven by stellar feedback are an essential part of the galactic ecosystem and are the main mechanism through which low-mass galaxies regulate their star formation. These winds are generally observed to be multi-phase with detections of entrained neutral and molecular gas. They are also thought to enrich the circum-galactic medium around galaxies with metals and dust. This ejected dust encodes information about the integrated star formation and outflow history of the galaxy. It is therefore, important to understand how much dust is entrained and driven out of the disc by galactic winds. Here we demonstrate that stellar feedback is efficient in driving dust-enriched winds and eject enough material to account for the amount of extraplanar dust observed in nearby galaxies. The amount of dust in the wind depends on the sites from where they are launched, with dustier galaxies launching more dust enriched outflows. Moreover, the outflowing cold-dense gas is significantly more dust-enriched than the volume filling hot tenuous material, naturally reproducing the complex multiphase structure of the outflowing wind observed in nearby galaxies. These results provide an important new insight into the dynamics, structure, and composition of galactic winds and their role in determining the dust content of the extragalactic gas in galaxies.

description: A percolation model is proposed to explain the structural phase transitions found in Li$_{1-x}$H$_x$IO$_3$ mixed crystals as a function of the concentration parameter $x$. The percolation thresholds are obtained from Monte Carlo simulations on the specific lattices occupied by lithium atoms and hydrogen bonds. The theoretical results strongly suggest that percolating lithium vacancies and hydrogen bonds are indeed responsible for the solid solution observed in the experimental range $0.22 < x < 0.36$.

title: The One-shot Deal: Temporary Organizations, UK Feature Film Units, and Learning Organization Theory
Creators: name: Ludwin, Linda Grace
Publisher: name: The Open University
Year: 2003

description: This embedded single case study considers how temporary organizations such as UK feature film production units learn. Units, which cluster around London and are active for less than a year, manufacture pre financed films such as Four Weddings and a Funeral and The Crying Game. Six important learning organization models, three from the UK and three from the USA, were used to think about how film units learn. Primary and secondary data were considered in function of six themes. Three were learning organization themes: (i) learning is tied to action, (ii) problem solving, and (iii) commitment to learning. Further powerful themes emerged during coding: (iv) temporariness, (v) employment practices, and (vi) networking. Fieldwork consisted of in-depth interviews with freelances working on UK film units, as well as a range of other primary and secondary sources, including days of observation during the production of Loaded, and attendance at a series of British Film Institute seminars on film production issues. The study concludes that although UK feature film units are epistemic communities, they are not learning organizations. The combination of being temporary and producing cultural texts conditions most aspects of organizational life and style in UK film units. They are an extreme and idiosyncratic form of temporary organization, designed to thrive in climates of radical change and grounded in a unique historical context.

description: A constructive procedure is proposed for formulation of linear differential equations invariant under global symmetry transformations forming a semi-simple Lie algebra f. Under certain conditions f-invariant systems of differential equations are shown to be associated with f-modules that are integrable with respect to some parabolic subalgebra of f. The suggested construction is motivated by the unfolded formulation of dynamical equations developed in the higher spin gauge theory and provides a starting point for generalization to the nonlinear case. It is applied to the conformal algebra o(M,2) to classify all linear conformally invariant differential equations in Minkowski space. Numerous examples of conformal equations are discussed from this perspective.

description: We study the formation of localized patterns arising in doubly resonant dispersive optical parametric oscillators. They form through the locking of fronts connecting a continuous-wave and a Turing pattern state. This type of localized pattern can be seen as a slug of the pattern embedded in a homogeneous surrounding. They are organized in terms of a homoclinic snaking bifurcation structure, which is preserved under the modification of the control parameter of the system. We show that, in the presence of phase mismatch, localized patterns can undergo oscillatory instabilities which make them breathe in a complex manner.

description: In this paper asymmetric price transmission mechanism and nonlinear adjustment between producer and retail prices of milk were examined in Zanjan Province of Iran. For this purpose, a Two-Regime Threshold Vector Error Correction Model (TVECM) and a Sup-LM Test developed by Hansen and Seo (2002) were employed for checking presence of a threshold effect. Application of unit root tests indicated that both wholesale and retail prices are I (1), and Johansen test verified cointegration of the series in the long-run. Results of the Sup-LM test confirmed threshold adjustment of product price towards the long-run equilibrium. Furthermore, results obtained from TVECM revealed that the coefficient of ECT is significant only in the first regime of retailing equation implying that retailers significantly respond to the decreasing deviations from the long-run equilibrium. While adjustment coefficient is not significant for wholesale equation in both regimes to imply that there is not significant inclination to react to deviations from the long-run equilibrium among the wholesalers despite the retailers.

description: 1-3 per cent of white dwarfs are orbited by planetary dusty debris detectable as infrared emission in excess above the white dwarf flux. In a rare subset of these systems, a gaseous disc component is also detected via emission lines of the Ca II 8600Å triplet, broadened by the Keplerian velocity of the disc. We present the first statistical study of the fraction of debris discs containing detectable amounts of gas in emission at white dwarfs within a magnitude and signal-to-noise limited sample. We select 7705 single white dwarfs spectroscopically observed by the Sloan Digital Sky Survey (SDSS) and $Gaia$ with magnitudes $g$ $\leq$ 19. We identify five gaseous disc hosts, all of which have been previously discovered. We calculate the occurrence rate of a white dwarf hosting a debris disc detectable via Ca II emission lines as 0.067$\pm$$_{0.025}^{0.042}$ per cent. This corresponds to an occurrence rate for a dusty debris disc to have an observable gaseous component in emission as 4$\pm$$_{2}^{4}$ per cent. Given that variability is a common feature of the emission profiles of gaseous debris discs, and the recent detection of a planetesimal orbiting within the disc of SDSSJ122859.93+104032.9, we propose that gaseous components are tracers for the presence of planetesimals embedded in the discs and outline a qualitative model. We also present spectroscopy of the Ca II triplet 8600Å region for 20 white dwarfs hosting dusty debris discs in an attempt to identify gaseous emission. We do not detect any gaseous components in these 20 systems, consistent with the occurrence rate that we calculated.

For data analyzing the comparative advantage and government policies effects indices, Policy Analysis Matrix (PAM) were used. The obtained results for the comparative advantage indices of Domestic Resource Cost (DRC), Social Cost Benefit (SCB) and Net Social Profitability (NSP) show that production of irrigated wheat, dry-farming wheat and dry-farming barely has not comparative advantage in Ilam Province but the production of irrigated barely, corn, dry-farming pea, dry-farming lentil, watermelon, cucumber and tomato have comparative advantage in Ilam Province. In addition, the obtained results for NPIC index show the Nominal Government Protection of inputs in all products. Also, Nominal Protection Coefficient index indicated that nominal market protection of products like wheat (irrigated and dry-farming) and barely (irrigated and dry-farming) was positive and those of other products were negative and the Effective Protection Coefficient for wheat and barley had the highest values. The results showed that the existing cropping pattern was not allotted with comparative advantage but is related to the effective protection coefficient

description: Agriculture and its development is the foundation of development in Iran as a developing country. So, it can be regarded as the foundation for economical and social development. The capabilities of agriculture sector are limited and its efficiency is trivial because of neglecting agricultural development and keeping its support just as a slogan. The trans- formation of agriculture to a developed, dynamic, efficient environment depends not only on appropriate climate and natural resources but also on human resource development in the relevant sector. The main purpose of the present research was to study and recognize agricultural development indicators from agriculture experts’ viewpoints (including researchers, trainers and extension experts) in six provinces in Iran on the basis of Adjacent Provinces Plan. The study was designed with three phases of theoretical foundations, field operations and data analysis. The statistical population was 863 experts, out of which 198 experts were selected by stratified sampling. The validity and reliability of measurement tool (questionnaire) was analyzed by SPSS software package. The study was a correlation-descriptive study in which factor analysis statistics was used in addition to descriptive statistics. Experts grouped indicators of future agricultural development in nine groups (access to inputs, application of technologies for the development of human resource and sustainability; reduction of losses; economical development; improvement of infrastructures; agricultural mechanization; social status; improvement of marketing; land reform; yield increase). Results about the difference in respondents’ viewpoints revealed significant differences in experts’ viewpoints in six studied province about relevant variables and in their viewpoints about the components of agricultural development (infrastructure improvement, marketing, optimum management and sustainability, human resource development and economical development).

description: This paper assesses the views expressed by Gary Becker and Richard Posner about the economic value of relying on microfinancing for economic development as well as their opinions about its desirability as a means of alleviating poverty. It also raises some issues overlooked by Becker and Posner. Where relevant, the discussion is related to results obtained from a case study of microfinancing in the Sindh District of Pakistan. Subjects covered include the economic efficiency of the supply of microfinance, the optimality of microfinancing versus philanthropy, whether high interest rates and short-term loans for microfinance are justified, preference for females rather than males in microfinancing, social networking and the efficient provision and allocation of microfinance, and the prospects for escaping from poverty as a result of microfinancing.

description: (Abridged) A high fraction of the Low Mass X-ray Binaries (LMXBs) in early-type galaxies are associated with globular clusters (GCs). Here, we discuss the correlations between LMXBs and GCs in a sample of four early-type galaxies. There is some evidence that the fraction of LMXBs associated with GCs (f_X-GC) increases along the Hubble sequence from spiral bulges to S0s to Es to cDs. On the other hand, the fraction of globular clusters which contain X-ray sources appears to be roughly constant at f_GC-X ~ 4%. There is a strong tendency for the X-ray sources to be associated with the optically more luminous GCs. However, this correlation is consistent with a constant probability of finding a LMXB per unit optical luminosity; it seems to result primarily from the larger number of stars in optically luminous GCs. The probability of finding a bright LMXB per unit optical luminosity in the GCs is about 1.5e-7 LMXBs per L_solar,I for L_X >~ 1e38 erg/s, and rises to about 2.0e-7 LMXBs per L_solar,I at lower X-ray luminosities, L_X >~ 3e37 erg/s. This frequency appears to be roughly constant for different galaxies, including the bulges of the Milky Way and M31. There is a tendency for the X-ray sources to be found preferentially in redder GCs. This seems to indicate that the evolution of X-ray binaries in a GC is affected either by the metallicity or age of the GC, with younger and/or more metal rich GCs having more LMXBs. There is a weak tendency for the brightest LMXBs, whose luminosities exceed the Eddington luminosity for a 1.4 M_solar neutron star, to avoid GCs. That may indicate that black hole X-ray are somewhat less likely to be found in GCs, as seems to be true in our Galaxy.

description: Species prioritization is a crucial step towards setting valuation strategy, especially for Non timber Forest Products (NTFP). This study aimed at assessing the diversity and ranking NTFPs for a successful economic valuation. Data were collected through literature review. Seven prioritization criteria were used in different prioritization systems. The top 50 NTFP species obtained by each system were identified and ten NTFP of highest priority occurring as priority across methods were selected. A total of 121 NTFPs belonging to 90 botanical genera and 38 botanical families were found. The top 10 priority were: Vitellaria paradoxa, Parkia biglobosa, Adansonia digitata, Irvingia gabonensis, Blighia sapida, Tamarindus indica, Dialium guineense, Vitex doniana, Borassus aethiopum and Garcinia kola. Due to the economic potential and the regional importance of these priority species, appropriate incentives for their valuation are needed and should be reflected in forest policies in Benin.

description: We present the results of 26 nights of CCD photometry of the nova V2540 Oph (2002) from 2003 and 2004. We find a period of 0.284781 +/- 0.000006 d (6.8347 +/- 0.0001 h) in the data. Since this period was present in the light curves taken in both years, with no apparent change in its value or amplitude, we interpret it as the orbital period of the nova binary system. The mass-period relation for cataclysmic variables yields a secondary mass of about 0.75 +/- 0.04 Msun. From maximum magnitude - rate of decline relation, we estimate a maximum absolute visual magnitude of M(V)=-6.2 +/- 0.4 mag. This value leads to an uncorrected distance modulus of (m-M) = 14.7 +/- 0.7. By using the interstellar reddening for the location of V2540 Oph, we find a rough estimate for the distance of 5.2 +/- 0.8 kpc. We propose that V2540 Oph is either: 1) a high inclination cataclysmic variable showing a reflection effect of the secondary star, or having a spiral structure in the accretion disc, 2) a high inclination intermediate polar system, or less likely 3) a polar.

Global solution of viscous accretion disk around rotating compact objects: a pseudo-general-relativistic study

description: We study the solution of viscous accretion disks around rotating compact/central object having hard surface i.e. neutron star, strange star and any other highly gravitating objects. We choose pseudo-Newtonian approach to describe the relativistic accretion disk. For this purpose, the new pseudo-Newtonian potential is used which is applicable to describe the relativistic properties of star and its disk. As we know, the Hartle-Thorne metric can describe geometry of star as well as the space-time out-side of it, we use this metric for our study. This potential reproduces the marginally stable orbit exactly as that of general relativity. It also reproduces the marginally bound orbit and specific mechanical energy at the marginally stable orbit with at most 4% and 10% error respectively. Using this potential we study the global parameter space of the accretion disk. Thus, we find out the physical parameter regime, for which the stable accretion disk can be formed around gravitating object with hard surface. We show that with the change of rotation to the central object, the valid disk parameter region dramatically changes. We also show the effect of viscosity to the fluid properties of the disk. Subsequently, we give a theoretical prediction of kHz QPO, at least for one out of a pair, for a fast rotating compact object as 4U 1636-53.

description: Wetland hydrology is important in understanding wetland systems, evaluating wetland functions and processes and assessing wetland conditions. Wetlands assimilate and transform pollutants and nutrients ensuring that quality water is discharged from the wetland into streams. The objective of this study was to characterise wetland hydrology and evaluate the water quality so as to determine the ecological functioning of the Khalong-la-Lithunya wetland. Wetland hydrology and water quality of the three sub-catchments were monitored from October 2015 to March 2016. Water levels in piezometers were recorded once a month and monthly water levels data for the years 2010, 2011, 2012 and 2013 previously recorded by the Millennium Challenge Account-Lesotho (MCA-L) project were integrated to this study’s data. Rainfall, piezometer and stream water were similarly obtained once every month. These were analysed for δ2H and δ18O water stable isotopes and water quality parameters determined. The estimated overall hydro-period of Khalong-la-Lithunya from the years 2010 to 2016 was 11.4% of the sampled time. The wetland showed delayed response of piezometer water levels to rainfall and additional source of water to the wetland through sub-surface flow. The isotopic composition of piezometer and stream water showed that the water gets stored in the wetland before being discharged to the stream leading to a positive interaction between ground and surface water. Most water quality parameters (Na, pH, Mg, PO4 , COD, BOD, NO3, K, Ca, EC) were higher in streams than in piezometers and were mostly within WHO permissible limits. There was a poorer water quality index in streams (59.71) when compared to that of piezometers (53.67). The principal component analysis (PCA) indicated that the parameters that were responsible for the variation in water quality were related to natural hydro-chemical processes, anthropogenic factors and geology and soil constituents. Temporally most parameters were highest during dry months. Due to a short hydro-period, a delayed interaction between surface and ground water and a poorer stream water quality index, it is concluded that the wetland was not in a good condition. Thus, it is not adequately performing its ecological function.
