description: We accomplish our efforts to obtain predictions for all four-fermion final states of e+ e- annihilation and the corresponding bremsstrahlung reactions which are possible in the framework of the Standard Model. For this purpose we have developed a program EE4FGAMMA. Our predictions are valid for fermions of arbitrary masses and we can obtain results for total cross sections without any collinear cut. Keeping exact fermion masses is of course required for top quark production. We give a detailed phenomenological analysis of fermion mass effects and real photon radiation for all channels of four-fermion production at LEP-II and next linear collider energies.

Nonclassicality and information exchange in deterministic entanglement formation
Creators: name: de Oliveira, M. C.

Publisher: name: arXiv
Year: 2002
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We discuss the role of nonclassicality of quantum states as a necessary resource in deterministic generation of multipartite entangled states. In particular for three bilinearly coupled modes of the electromagnetic field, tuning of the coupling constants between the parties allows the total system to evolve into both Bell and GHZ states only when one of the parties is initially prepared in a nonclassical state. A superposition resource is then converted into an entanglement resource.
description: Replaced by the accepted version. Two optical implementations of the quantum resource conversion protocol are now proposed. To appear in Phys. Lett. A. 7 pages, 1 figure

description: The origin of the multi-band activities (outbursts/flares) of blazars is still a heavily debated topic. Shock and magnetic reconnection have long been considered as possible triggers for the multi-band activities. In this paper, we present an exploration of the origin of multi-band activities for a high-redshift (z =1.8385) FSRQ PKS 1502+106. Utilizing multi-band data from radio to $γ$-ray and optical polarization observations, we investigate two dramatic activities in detail: a $γ$-ray dominated outburst in 2015 and an optical dominated outburst in 2017. Our main results are as follows. (I) A fast $γ$-ray flare with a flux-doubling time-scale as short as 1-hr in 2015 is discovered. Based on the variability time-scale, the physical parameters of the flaring region (e.g, minimum Doppler factor, emission region size, etc.) are constrained. At the peak of the flare, the $γ$-ray spectrum hardens to $Γ_γ = 1.82\pm0.04$ and exhibits an obvious curvature/break characteristic that is caused by the typical "cooling break". Modelings of multi-band SEDs reveal a very hard electronic energy spectrum with the electronic spectral index of $1.07\pm0.53$. This result suggests that this fast $γ$-ray flare may be triggered by magnetic reconnection. (II) During the outburst in 2017, the optical polarization degree and optical fluxes show a very tight correlation. By analyzing Stokes parameters of polarization observations, our results show that this outburst could be triggered by a transverse shock with a compression ratio of $η> 2.2$, and the magnetic field intensity of the shock emission region is about $0.032$ G.

description: 3D nanowire networks are fascinating systems for future microelectronic devices. They can be handled like macroscopic objects, while exhibiting properties of nanoscale materials. Here, the fabrication of free‐standing 3D bismuth nanowire networks with well‐controlled and systematically adjusted wire diameter and interconnectivity is presented. The samples are fabricated by pulse electroplating of bismuth into the pores of ion track‐etched membranes using an aqueous electrolyte. By optimizing the growth parameters, homogeneously grown, mechanically self‐supporting and free‐standing networks without a supporting matrix are achieved. Cross‐plane Seebeck coefficient and electrical resistance values are investigated as a function of nanowire diameter and temperature. The unique characteristics of these highly interconnected and mechanically self‐supported Bi 3D nanowire networks offer exciting perspectives for their implementation in, e.g., infrared detection based on thermoelectric effects, sensing, and THz applications.

description: We forecast astrophysical and cosmological parameter constraints from synergies between 21 cm intensity mapping and wide field optical galaxy surveys (both spectroscopic and photometric) over $z \sim 0-3$. We focus on the following survey combinations in this work: (i) a CHIME-like and DESI-like survey in the northern hemisphere, (ii) an LSST-like and SKA I MID-like survey and (ii) a MeerKAT-like and DES-like survey in the southern hemisphere. We work with the $Λ$CDM cosmological model having parameters $\{h, Ω_m, n_s, Ω_b, σ_8\}$, parameters $v_{c,0}$ and $β$ representing the cutoff and slope of the HI-halo mass relation in the previously developed HI halo model framework, and a parameter $Q$ that represents the scale dependence of the optical galaxy bias. Using a Fisher forecasting framework, we explore (i) the effects of the HI and galaxy astrophysical uncertainties on the cosmological parameter constraints, assuming priors from the present knowledge of the astrophysics, (ii) the improvements on astrophysical constraints over their current priors in the three configurations considered, (ii) the tightening of the constraints on the parameters relative to the corresponding HI auto-correlation surveys alone.

description: A linear electron-positron collider operating at TeV scale energies will provide high precision measurements and allow, for example, precision studies of the Higgs boson as well as searches for physics beyond the standard model. A future linear collider should produce collisions at high energy, with high luminosity and with a good wall plug to beam power transfer efficiency. The luminosity per power consumed is a key metric that can be used to compare linear collider concepts. The plasma wakefield accelerator has demonstrated high-gradient, high-efficiency acceleration of an electron beam, and is therefore a promising technology for a future linear collider. We will go through the opportunities of using plasma wakefield acceleration technology for a collider, as well as a few of the collider-specific challenges that must be addressed in order for a high-energy, high luminosity-per-power plasma wakefield collider to become a reality.

description: Viticulture and wine production are important industries in most of the countries who have signed CEFTA agreement. The countries of this region have favorable environmental conditions for a high production of grapes and wine. The subject and purpose of the research is to understand the trends of production, export and import in the countries of CEFTA region. Source of data is FAO database (Food and Agriculture Organization - FAO), for the time period 2000-2009. Average wine production in the given region is 610 million liters with a tendency of slight decrease at an average annual rate of 2.81%. Average wine export for countries of this group is the 243.5 million liters, with a tendency of slight decrease at a rate of 1.74%. Export price of wine is 0.9 dollars per liter, which indicates that lowerquality categories of wine (table wine) are mainly being exported. The most important exporter is Moldova with the participation of 63% of total exports from the region. Import of wine is 50 million liters with a trend of significant growth at an average rate of 12.44% per year. The largest importer is the Republic of Serbia with a share of 46.7% of the region. Countries in the region are achieving a positive trade balance of wine, averagely over 190 million liters. It is necessary to increase the production of wine with changes in the structure with regard to quality.

description: We present a detailed temporal and spectral study of the intermediate type blazar, ON 231 with observations taken by Swift and XMM-Newton satellites during an outburst phase in June 2008. The source shows multiple X-ray flares in that period when the flux amplitude varies in the range of 27-38%. The X-ray spectra are well fitted with a broken power-law model indicating the presence of both synchrotron and inverse Compton components. We find that the source shows strong and variable emission in the soft energy bands (below 3-4 keV), where the hard band emission is weak and stable. All the soft X-ray bands show correlated variability with zero lag, while a soft lag of -600 s between the 0.3-0.5 and 4-10 keV bands is observed with DCF analysis. A time-resolved spectral study of the flares gives a positive relation between the total fluxes and the break energies of the two emission components.

Crowding-out Effect of Public Borrowing in Sri Lanka
Creators: name: Nawalage L.A.Cooray
Publisher: name: figshare
Year: 2019
Subjects: Economics

description: The government of Sri Lanka has been disproportionately borrowing from the domestic banking and non-banking sectors to finance its budget deficit. These sectors also serve as funding sources for the country's private investors. The government's expansionary fiscal policy has increased its total income, but it may also raise interest rates and reduce private investment. This study estimates the crowding-out effect of public borrowing from domestic sources on private investment in Sri Lanka. Using time-series data from 1960-2014 sourced from the Central Bank of Sri Lanka and World Development Indicators, we develop an investment function with three independent variables, public borrowing, interest rate, and gross domestic product. Unit root tests and the autoregressive distributed lag and vector error correction models are also utilized. To test the long-run relationships among the variables, we conduct a bound test of co-integration, and the results show that there is long-run co-integration between the variables. Vector autoregressive models, variance decomposition analysis, the Granger causality test, and impulse response functions are used to analyse the results. The study provides evidence for the absence of a crowding-out effect in Sri Lanka as a result of public borrowing from domestic sources. This evidence has important implications of fiscal management in Sri Lanka. To avoid external indebtedness and unnecessary inflation due to debt financing, the government can rely on domestic sources without hurting private investment in the country.

description: Modern industrial production of food products is characterized by the use of certain additives. The food science, by using the modern diagnostic methods, significantly affects the new findings regarding the harmless or harmfully effect of certain substances. The important trends in food industry production of food products today is implementation of natural ingredients. It is possible to obtain extracts (essential oil) with antioxidant characteristics. The paper points out the importance of certain separation process for isolating natural ingredients from drugs. The aim of this paper is to compare different extraction techniques such as distillation with steam, hydro distillation, the application of classical organic solvents and supercritical extraction (SCFE) in production of essential oil. To obtain these goals, the following works will be carried out: investigate the chemical composition of essential oil, investigate the effects of quality and yield, the selection of the operating conditions depends on the specific compound or compound family to be extracted. There are five crucial parameters that need to be taken into account of essential oils including: extraction temperature, extraction pressure, extraction time, CO2 flow rate and particle size. The SCFE method offers many important advantages over hydro distillation.

description: We derive similarity solutions for the expansion of negative initial density perturbations δM/M \propto r^-s (s>0) in an Einstein-de Sitter universe filled with collisional baryonic gas and collisionless matter. The solutions are obtained for planar, cylindrical, and spherical perturbations. For steep perturbations, central cavities surrounded by over-dense shells expanding as t^{2(s+1)/3s} develop in both matter components. We also consider the case when baryonic shells are driven by internal pressure. Before redshift \sim 8-10 baryonic shells cool by inverse Compton scattering with the cosmic background radiation and can form bound objects of mass \sim 10^11Ω_b^{-1/2} M_{\odot} (1+z)^{-3/2}. Hot shocks of radius R cause a Compton y-distortion of order y=10^{-5}Ω_b (R/10 Mpc)^2 f_F, where f_F is the volume filling factor of these shells.

description: Learn and Apply is a 2-step reconstruction scheme for Adaptive Optics (AO) instruments, and has recently been
extended to include a predictive step, i.e., predictive Learn and Apply (pLA). It estimates the pseudo-real-time
atmospheric turbulence profile directly from the AO telemetry buffer (the so-called Learn step), and then performs
tomographic reconstruction based on the outputs (the so-called Apply step). We implement the entire pLA
pipeline in end-to-end simulations, where both the Learn and the Apply steps are performed in turns. We present
the results of these simulations, as well as the challenges that were encountered and overcome in particular, the
challenges which have had an impact on the design of the MAVIS AO module.

description: In mid-2009 the Republic of Serbia adopted the Law on plant protection products (pesticides) and the Law on plant nutrition products (fertilizers), which are in accordance with relevant international legislation, particularly with the regulations and directives of the European Union. In this way, these laws created the basis for establishing a modern system in the area, which will be finished after the adoption of rules on specific technical issues. The new legal framework has made changes regarding liberalization of foreign trade of plant protection products, and plant nutrition products, as well as has introduced few registers. In the area of pesticides were determined: the Register of Plant Protection Products, Register of Distributors and Importers of Plant Protection Products, and Register of Providers of the Services. Also, the Register of Plant Nutrition Products was determined. In addition, the registration of pesticides and fertilizers was modified to be in accordance with internationally recognized testing methods.

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

description: We calculate the three-point functions in the sine-Liouville theory explicitly. The same calculation was done in the (unpublished) work of Fateev, Zamolodchikov and Zamolodchikov to check the conjectured duality between the sine-Liouville and the SL(2,R)/U(1) coset CFTs. The evaluation of correlators boils down to that of a free-field theory with a certain number of insertion of screening operators. We prove that the winding number conservation is violated up to (+-)1 in three-point functions, which is in agreement with the result of FZZ that in generic N-point correlators the winding number conservation is violated up to N-2 units. A new integral formula of Dotsenko-Fateev type is derived, using which we write down the generic three-point functions of tachyons explicitly. When the winding number is conserved, the resultant expression is shown to reproduce the correlators in the coset model correctly, including the group-theoretical factor. As an application, we also study the superstring theory on linear dilaton background which is described by super-Liouville theory. We obtain the three-point amplitude of tachyons in which the winding number conservation is violated.

description: Differential graphical models are designed to represent the difference between the conditional dependence structures of two groups, thus are of particular interest for scientific investigation. Motivated by modern applications, this manuscript considers an extended setting where each group is generated by a latent variable Gaussian graphical model. Due to the existence of latent factors, the differential network is decomposed into sparse and low-rank components, both of which are symmetric indefinite matrices. We estimate these two components simultaneously using a two-stage procedure: (i) an initialization stage, which computes a simple, consistent estimator, and (ii) a convergence stage, implemented using a projected alternating gradient descent algorithm applied to a nonconvex objective, initialized using the output of the first stage. We prove that given the initialization, the estimator converges linearly with a nontrivial, minimax optimal statistical error. Experiments on synthetic and real data illustrate that the proposed nonconvex procedure outperforms existing methods.

description: Financial statements of agricultural enterprises are an important source of information for assessing the effects of using resources and consideration of the effects of the company. Based on the financial statements of agricultural enterprises, users make important decisions to agriculture, and thus overall economic activity. In order to make reliable and appropriate decisions it is necessary to provide quality financial statements that contain complete and accurate information about position and results of agricultural enterprises. This will provide information for efficient evaluation of business performance of agricultural enterprises. Accordingly, this paper provide the results of research the quality of financial reporting of biological assets in the Republic of Serbia in the period 2008- 2010. In this period there is a growing number of companies that adopted the requirements of standard, but the quality of financial reporting of biological assets is not satisfactory. Full disclosure of information accordnig to standard first appears in 2010. year in only 6.67% of all investigated financial statements.

description: Tracer-kinetic analysis of dynamic contrast-enhanced magnetic resonance imaging data is commonly performed with the well-known Tofts model and nonlinear least squares (NLLS) regression. This approach yields point estimates of model parameters, uncertainty of these estimates can be assessed e.g. by an additional bootstrapping analysis. Here, we present a Bayesian probabilistic modeling approach for tracer-kinetic analysis with a Tofts model, which yields posterior probability distributions of perfusion parameters and therefore promises a robust and information-enriched alternative based on a framework of probability distributions. In this manuscript, we use the Quantitative Imaging Biomarkers Alliance (QIBA) Tofts phantom to evaluate the Bayesian Tofts Model (BTM) against a bootstrapped NLLS approach. Furthermore, we demonstrate how Bayesian posterior probability distributions can be employed to assess treatment response in a breast cancer DCE-MRI dataset using Cohen's d. Accuracy and precision of the BTM posterior distributions were validated and found to be in good agreement with the NLLS approaches, and assessment of therapy response with respect to uncertainty in parameter estimates was found to be excellent. In conclusion, the Bayesian modeling approach provides an elegant means to determine uncertainty via posterior distributions within a single step and provides honest information about changes in parameter estimates.

Subjects: Economics

description: The aim of this paper is to model and forecast the infrastructure investment needs in Lebanon. It divides the Lebanese infrastructure into ten main sectors, and it represents an analysis of each sector. The article collects data of the government expenditures on projects for each sector from the Lebanese council of development and reconstruction. The expenditure on each sector represents a different impact on the Lebanese growth and the Gross Domestic Product, the article analyses the impact in an assessment approach. Findings emphasis the importance of social infrastructure in promoting growth, especially Education sector. Furthermore, findings stress the high volume of expenditure on waste water and solid waste management sector. The article proceeds by modeling the infrastructure investment need using Dynamic OLS equilibrium. The study encloses ten Dynamic OLS models, one for each sector, having the investment needs as the dependent variable, and as independent variables the Lebanese Gross Domestic Product and the Lebanese population. Eventually, the paper forecasts the Lebanese infrastructure investment needs for each sector until the year 2025. Results emphasis the unfair low expenditure on Education and other social infrastructures, and the high expenditures on inefficient sectors such as the waste water and solid waste sector, and the electricity sector. The study eventually recommends a better distribution of infrastructure investments within the Lebanese expenditures.

description: The paper examines the prospective role which wine tourism could play in the rural and in the much needed overall economic development of Armenia. It begins with a brief description of the antique origin and the present economic situation of the wine sector in Armenia, followed by a description of recent trends in the tourist sector as a whole in Armenia. The particular features of wine tourism are examined in relation to Armenia and to other wine producing countries. Attention is then concentrated on a specific region of Armenia, Vayots Dzor, which is particularly important for wine production, and is also endowed with historical monuments with great potential for the development of tourism. The case of one particular village is illustrated in some detail in order to indicate how tourism in general, and specifically wine tourism could be developed for the benefit of the rural community. The paper concludes by outlining a strategy to be followed to achieve the growth of the sector.

description: Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of sensitivity, speed, operating temperature, and spectral range. Here, we use graphene as a photoactive material to overcome all of these limitations in one device. We introduce a novel detector for terahertz radiation that exploits the photothermoelectric (PTE) effect, based on a design that employs a dual-gated, dipolar antenna with a gap of 100 nm. This narrow-gap antenna simultaneously creates a pn junction in a graphene channel located above the antenna and strongly concentrates the incoming radiation at this pn junction, where the photoresponse is created. We demonstrate that this novel detector has an excellent sensitivity, with a noise-equivalent power of 80 pW-per-square-root-Hz at room temperature, a response time below 30 ns (setup-limited), a high dynamic range (linear power dependence over more than 3 orders of magnitude) and broadband operation (measured range 1.8-4.2 THz, antenna-limited), which fulfills a combination that is currently missing in the state-of-the-art detectors. Importantly, on the basis of the agreement we obtained between experiment, analytical model, and numerical simulations, we have reached a solid understanding of how the PTE effect gives rise to a THz-induced photoresponse, which is very valuable for further detector optimization.

AdS/SCFT in Superspace

Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)

description: A discussion of the AdS/CFT correspondence in IIB is given in a superspace context. The main emphasis is on the properties of SCFT correlators on the boundary which are studied using harmonic superspace techniques. These techniques provide the easiest way of implementing the superconformal Ward identities. The Ward identities, together with analyticity, can be used to give a compelling argument in support of the non-renormalisation theorems for two- and three-point functions, and to establish the triviality of extremal and next-to-extremal correlation functions. The OPE in is also briefly discussed.

Seiberg-Witten Curve for E-String Theory Revisited

description: We discuss various properties of the Seiberg-Witten curve for the E-string theory which we have obtained recently in hep-th/0203025. Seiberg-Witten curve for the E-string describes the low-energy dynamics of a six-dimensional (1,0) SUSY theory when compactified on R^4 x T^2. It has a manifest affine E_8 global symmetry with modulus τand E_8 Wilson line parameters {m_i},i=1,2,...,8 which are associated with the geometry of the rational elliptic surface. When the radii R_5,R_6 of the torus T^2 degenerate R_5,R_6 --> 0, E-string curve is reduced to the known Seiberg-Witten curves of four- and five-dimensional gauge theories. In this paper we first study the geometry of rational elliptic surface and identify the geometrical significance of the Wilson line parameters. By fine tuning these parameters we also study degenerations of our curve corresponding to various unbroken symmetry groups. We also find a new way of reduction to four-dimensional theories without taking a degenerate limit of T^2 so that the SL(2,Z) symmetry is left intact. By setting some of the Wilson line parameters to special values we obtain the four-dimensional SU(2) Seiberg-Witten theory with 4 flavors and also a curve by Donagi and Witten describing the dynamics of a perturbed N=4 theory.

description: This paper aims to highlight the state intervention in environmental issues through application of the relevant regulations and economic instruments. The emphasis is on the connection between the economic relations and the environment. Through the adoption of the strategy of sustainable development (according to the Rio Declaration on Sustainable Development and Environmental Protection) the state authorities should reinforce the use of economic instruments in financing the environment and providing the implementation of the basic principles of “sustainability”, based on the application of the “polluter pays” and “user pays” principles. The application of the principles of sustainable development at the national, regional, local and company level means the application of economic instruments in the environmental field. Economic, market-based, planning and other instruments of environmental protection should be part of the global system of managing the environment and part of the production management (at the company level).

description: AbstractThe risks that banks face have been exacerbated by the globalization and liberalization of the financial markets.The liberalization of the financial markets has exposed banks to a plethora of risks such as credit risk, liquidityrisk, operational risk, counterparty risk, regulatory risk, systematic and reputational risks. A recurring discourse inthe risk management literature is the perceived concentration of regulatory authorities on credit risk. This topic isreconsidered in this paper to critically evaluate the different risk types and to interrogate the assertion thatregulatory authorities have focused more on credit risks of banks while shying away from other possible risks thatbanks face. Reviewing contemporary literature and regulatory interventions, we conclude that contrary to theclaims that regulatory interventions have focused on credit risk of banks, attempts have been made to address inbroad terms the gamut of risks that banks face

description: Valuation of investments and investment projects is a very important social activity. However, by the development of productive forces, accompanied by an accelerated exploitation of natural resources, and by growing of social expectations in the modern communities, investment decision-making includes also alternative economic opportunities. In such circumstances, the choice of the project is considered to be rational and justifiable only if it is better than others even in these non-economic areas. Therefore, consideration of investment projects in terms of their future impact on the wider social community is more and more important. Investments affect economic growth and social well-being, but in modern circumstances their role is significantly changed, especially in terms of sustainability. Therefore the EU increasingly encourages the corporate social responsibility in long-term strategies and plans of the companies, as well as the use of the methodology for evaluation of the social justifiability of investment projects. Also, there are other methodologies for evaluation of the social justifiability of investment projects, as it is the case with the methodology of the UN, which confirms that this area is extremely important in global relations.
