Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Differential cross sections of secondary particles in a process of top quark pair production and decay into six fermions at a linear collider with an unpolarized and a longitudinally polarized electron beam are computed to the lowest order in the standard model and in the presence of an anomalous Wtb coupling. It is illustrated that the latter has a little impact on the differential cross sections. In particular, it is shown that the angular distribution of a secondary lepton receives practically no contribution from the anomalous Wtb coupling, even if the top quark is produced off shell and the non-double resonance background contributions are taken into account. This finding is in accordance with the decoupling theorem that has been proven in literature in the narrow top quark width approximation.

description: Magnetic pulse welding provides high quality joining of fuel pin cladding for fast nuclear reactors. The tool coil there operates under the most stressful conditions: 40 T magnetic fields with tens of microseconds duration. This requires minimal coil inductance and affects the capabilities and lifetime of the coils. Two approaches are being practiced to enhance the coil durability: material research and construction optimization. The first approach considers the use of high strength steels or composite materials for the coil working area. The present work is aimed to realize the second approach – the use of multi position coils in order to maximize the number of parts welded in one coil. Experiments and finite element modeling were carried out for two designs of two- and four-position single-turn coils, which were made to process several workpieces in one current pulse. The main parameters measured and calculated were the magnetic field between the coil and the workpiece, and the ratio of its amplitude to the discharge current, Bm/Im. The currents flowing through the coils were about 700 kA, which correspond to the magnetic fields of 40–45 T. The FEM modeling revealed a 17–19% drop of the magnetic induction near the insulated slit, which, however, did not prevent the helium-tight joining of the tubes to the end plugs.

description: This paper describes a bioeconomic model of a coastal recreational fishery that combines standard models of fish population dynamics, recreational catch, and recreation site choice. The population model estimates the influence of water quality on overall fish abundance through the effects of dissolved oxygen (DO) on the survivorship of young juvenile fish. The catch model estimates the influence of fish abundance and water quality on anglers’ average catch rates. The recreation demand model estimates welfare effects and changes in trip demand from changes in catch rates. The bioeconomic model also accounts for the feedback on the fish population through changes in the overall harvest pressure in the recreational fishery on the fish stock. The population model is specified using data on survival and reproduction from the fisheries science literature and government reports, and the model is calibrated using average historic recreational harvest levels in and out of the study area and historic commercial harvest levels for the entire fishery. The catch model is estimated using data on a sample of anglers who fished for summer flounder, data on water quality conditions from 23 water quality monitoring stations, and fishery-independent data on fish abundance collected in bottom trawl surveys, all in Maryland’s coastal bays in 2002. The recreation demand model is estimated using data from a stated choice survey of anglers who fish for summer flounder on the Atlantic coast. The bioeconomic model is used to estimate the aggregate benefits to recreational anglers from several illustrative scenarios of changes in water quality. The results indicate that improving water quality throughout the range of the species could lead to substantial increases in the fish population and associated benefits to recreational anglers from increased catch rates. Water quality improvements confined to Maryland’s coastal bays alone would have much smaller impacts.

description: Recent announcements that the Cosmic Microwave Background (CMB) - the faint remnant of the Big Bang - is polarized have caused a stir among cosmologists. Such polarization has long been predicted but could not be detected, until the recent DASI and WMAP detections. The polarization is a signature of the motion of the primordial seeds that led to the galaxies and large-scale structure of the Universe observed today. Earlier measurements of tiny temperature fluctuations in the CMB have been used to infer the sizes of the primordial seeds. The polarization signature should help to determine the fundamental parameters of cosmology and to explain how large-scale structure arose [Highwire abstract].

description: global climate change. Solid-state lighting (SSL) is one recent example of an innovative technology, which has received considerable attention in the last several years. This emerging lighting technology has tremendous potential to become significantly more energy-efficient than lighting technologies that are currently used, such as incandescent and fluorescent lighting. The purpose of this report is to provide an overview on SSL technology for the U.S. Environmental Protection Agency (EPA) and to serve as a reference for future work in this technology area. This report was prepared using the methodological approach of a “technology assessment”. An overview of SSL is provided, and the drivers and barriers to its use as general illumination lighting are discussed. The report also highlights both potential environmental benefits and negative impacts, which might accompany the development and use of this emerging technology.

description: We determine the modal logic of fixed-point models of truth and their axiomatizations by Solomon Feferman via Solovay-style completeness results. Given a fixed-point model $\mathcal{M}$, or an axiomatization $S$ thereof, we find a modal logic $M$ such that a modal sentence $φ$ is a theorem of $M$ if and only if the sentence $φ^*$ obtained by translating the modal operator with the truth predicate is true in $\mathcal{M}$ or a theorem of $S$ under all such translations. To this end, we introduce a novel version of possible worlds semantics featuring both classical and nonclassical worlds and establish the completeness of a family of non-congruent modal logics whose internal logic is subclassical with respect to this semantics.

description: This study examines the determinants of environmental and economic performance for plants in three traditional smoke-stack industries: pulp and paper, oil, and steel. We combine data from Census Bureau and EPA databases and Compustat on the economic performance, regulatory activity and environmental performance on air and water pollution emissions and toxic releases. We find that plants with higher labor productivity tend to have lower emissions. Regulatory enforcement actions (but not inspections) are associated with lower emissions, and state-level political support for environmental issues is associated with lower water pollution and toxic releases. There is little evidence that plants owned by larger firms perform better, nor do older plants perform worse.

description: Investigations on the solar cycle variation of the properties of suprathermal populations (H and other heavy ions like $^4$He, $^3$He, C, O and Fe) in the solar wind are sparse and hence, poorly understood. In the present investigation, solar cycle variations of "quiet" time suprathermal elements are investigated using $<$ $\sim$ 1 MeV/n particle flux data obtained from Ultra-Low Energy Isotope Spectrometer on board Advanced Composition Explorer satellite during the solar cycle 23 and 24. The analysis reveals that helium ($^4$He) shows zero or positive lags with respect to sunspot numbers in solar cycle 23 while it shows zero or negative lag in solar cycle 24. On the contrary, although iron (Fe) shows zero or positive lag in cycle 23 similar to $^4$He, it shows only zero lag in cycle 24 and no negative lag is seen. Further, significant differences in the spectral indices are seen between $^4$He and Fe in cycle 24 compared to the cycle 23. These results suggest that generation mechanisms responsible for suprathermal $^4$He and Fe underwent changes in cycle 24 and these mechanisms are probably dependent on the first ionization potential and mass to charge ratio. This proposition gets credence from the fact that changes in the lag and spectral slopes for C and O are not significantly different in cycle 23 and 24.

description: There is a great deal of concern, both among environmental activists and the general public, about the affects of globalization on the environment. One particularly contentious issue is that of trade liberalization. However, is all the concern being shown for the effect of increased trade on the environment misplaced? Should we instead be focusing our efforts on the distortions created by domestic policies as a greater source of potentially adverse environmental effects? This paper compares the environmental impacts of different types of subsidies/restrictions on the US economy. The paper presents the results of several scenarios surrounding the removal of two types of restrictions: trade and domestic subsidies. The Global Trade Analysis Project (GTAP) model and database will be used to derive economic changes while the environmental effects will be assessed using the Trade and Environment Assessment Model (TEAM). TEAM converts national level economic outcomes into environmental. Aggregate measures of pollution indicate greater increases in the US from trade liberalization, mostly through changes in the agricultural sector.

description: Cellulose sulfate was synthesized by esterification of α-cellulose with concentrated sulfuric acid at −10°C in ethanol. Cellulose is mainly sulfated on 3-, 6- and 3, 6-positions of the cellulose. It acts as a heterogeneous catalyst for the ring-opening of epoxides with alcohols or anilines and the Friedel-Crafts reaction between N-benzylindole and crotonaldehyde at room temperature. Methanolysis of cyclic epoxides, styrene oxide, terminal aliphatic epoxides, and glycidyl ethers were carried out using the catalyst (0.4–6.8 mg/mmol of epoxide) and afforded the corresponding products in 53–97% isolated yields after 10 min–24 h. Cellulose sulfate was successfully recycled and reused up to 3 catalytic cycles for the ring-opening of styrene oxide with methanol.

description: During the electrohydraulic forming process a high current, up to one hundred of kilo amperes, is discharged between two electrodes immersed in a water tank. This creates plasma that generates a primary shock wave and secondary pressure waves. If these pressures are applied in a tube, it is then possible to deform dynamically this tube against a ring, leading to crimping. This process presents several advantages: it is possible to deform internally tubes of diameters ranging from a few millimetres to several centimetres, no lubrication is needed and because the process is dynamic, the spring back is limited and some materials can present an improved behaviour compared to quasi-static forming. In this paper, we present an original electrohydraulic crimping device. We successively present the operating principle of our system, the time evolution of the crimping pressure and the strain rate in the tube for two kinds of pulse shaper. Finally crimping tests are done to evaluate the efficiency of the process.

description: Purpose. Poverty in Pakistan mostly exists as a rural poverty rather than urban poverty and presents a desolate vision. Rural poverty shows divergence with respect to area, region or any other administrative division. The tenacious rise of rural poverty in the history of Pakistan with some omissions, it affords plenty of material and remains a lot of questions related to poverty in the mind of researchers. The current study focused on three main poverty measures i.e. incidence, depth and severity of rural poverty in the rice-wheat zone of Punjab, Pakistan (Middle Punjab). Methodology / approach. To overcome the existing poverty issues in the area, we utilize secondary datasets at districts, regions, provinces or at national levels collected from Pakistan Bureau of Statistics, Islamabad (PBS). Poverty assessment for the year 2011–2012 is analyzed through Foster Greer and Thorbecke (FGT) method. Moreover, the Logit model is also used to find out the empirical values existing in the datasets. Results. The fluctuations in rural poverty for the year 2011–12 in the existing zone was analyzed by using logit regression model and data source was Household Integrated Economic Survey (HIES). The incidence of uni-dimensional and multidimensional poverty in middle Punjab (2011–12) were 35.38 and 27.40 percent has been seen after estimations. Originality / scientific novelty. The education level, health services, availability of assets, facilities and age of household head are the key factors related to incidence, depth and severity of poverty. All the above mentioned factors have negative relation with poverty measures. Practical value / implications. The decline in poverty can be achieved via implementation of sharp economic activities including the dimensions as analyzed in the manuscript. At this point, policy makers did not pay attention on the key factors that influence rural poverty at regional levels. There is a dire need to make development in basic standards of life to alleviate poverty in a long way in the middle Punjab.

Methodology / approach. Two hypotheses were proposed and tested in the study. Samples of 125 were drawn. The data were analyzed using simple frequency tables and regression analysis. However, for the purpose of this study the Statistical Package for Social Sciences (SPSS) was employed. To ensure the accuracy of the study this research used the Yamane formula in determining sample size. The coefficient alpha (Cronbach’s alpha) was used to test the reliability of the measurement scale. Results. The study critically examined the influence Competitive Strategies on Corporate Performance of Small and Medium Enterprises. The research found out that cost leadership strategy has significant effect on cost reduction of small and medium enterprises indicating that when firms are adopt good cost leadership strategy, they tend to reduce their cost of operations. Originality / scientific novelty. The results of regression analysis revealed that adoption of competitive strategies usually impacts positively on the performance of the SMEs and that competitive strategy has significant relationship on company’s market share. Therefore it is important for small and medium enterprises to learn more innovative ways of pleasing and satisfying the needs of employees at work to increase sales turnover of their business. Practical value / implications. This study has further proven that organizations achieve a great efficiency gain by engaging in high differentiation strategy by creating products to respond to the evolving market. Based on the above findings, it is recommended that Competitive Strategies should be adopted in a way that would boost the performance of the SMEs organizations in general.

description: Magnetic pulse welding (MPW), a solid-state impact welding technique provides the ability to join a wide array of material combinations, whilst introducing little to no heat to the system and preserving the base metal microstructure. Impact velocity is one of the key criteria which determines the weldability of the joint during MPW. Experimental measurement of impact velocity in MPW across wide-ranging parameters is expensive and time-consuming. Therefore, guidelines for process selection and knowledge of relative influence of parameters on impact velocity is limited. This study presents the applicability of coupling finite element method (FEM) and artificial neural network (ANN) modelling to perform sensitivity analysis of MPW. The welding process was simulated using FEM, and multilayer modular feedforward networks based on the results from finite element simulations were developed. The results of the present study revealed that the coil cross sectional area and turns primarily governed the process, followed by the voltage. The relative sensitivity of the parameters remained independent of the material combination. Inclusion of shop floor applicable process parameters suggests that the developed ANN models can substantially narrow down experimental runs and simultaneously act as a decision support tool for end users.

The calculations are performed analytically using the Kimber-Martin-Ryskin (KMR) prescription with different implementation of kinematical constraint, reflecting the angular and strong ordering conditions. The relations between the differential and integral formulation of the KMR approach is discussed. Several phenomenological applications of the proposed TMD parton densities to the LHC processes are given.

description: The atmospheric depth where the energy deposit profile of secondary particles from extensive air showers (EAS) reaches its maximum, $X_{\rm max}$, is related to the primary particle mass. The mass composition of the ultra-high energy cosmic rays (UHECRs) can be inferred from measurements of $X_{\rm max}$ distributions in each energy interval, by fitting these distributions with Monte Carlo (MC) templates for four primary species (p, He, N and Fe). On the basis of simulations, we show that a high abundance of some intermediate elements in the $X_{\rm max}$ distributions, e.g. Ne or Si, may affect the quality of the fit and also the reconstructed fractions of different species with respect to their true values. We propose a method for finding the "best combination" of elements in each energy interval from a larger set of primaries (p, He, C, N, O, Ne, Si and Fe) which best describes the $X_{\rm max}$ distributions. Applying this method to the $X_{\rm max}$ distributions measured by the Pierre Auger Observatory (2014), we found that the "best combination" of elements which best describe the data suggest the presence of Ne or Si in some low energy bins for the EPOS-LHC model.

description: Purpose. The purpose of this article is to study the approaches to the development of economic and environmental vectors of the strategy of development of the agrarian sector of the economy in the context of inter-sectoral integration. Methodology / approach. The methodological tool of research is the systematic method of scientific knowledge of economic phenomena and processes. To clarify the essence of the category «inter-sectoral integration», «strategy», an abstract-logical method was used. In order to assess the level of integration and efficiency of using integrated resource formations, the method of analysis has been used. On the basis of the forecasting method, the threats and opportunities for the development of inter-sectoral integration with the simultaneous comparison of the potential strengths and weaknesses of the integrated formations and the assessment of their competitive positions in the long-term and short-term period are identified. Results. The theoretical, methodological and applied aspects of the strategy of development of inter-sectoral integration in the agrarian sector of the economy through the prism of organizational, economic and environmental factors are substantiated from the position of the system approach. The dynamics of the capitalization of integrated formations and the efficiency of the establishment of closed production cycles in the conditions of inter-sectoral integration are shown. Originality / scientific novelty. The directions of institutional changes in the state policy in the context of the strategy of development of inter-sectoral integration have been improved. Proposals on the formation of inter-branch links in integrated enterprises have been developed. Practical value / implications. As an example of the activities of integrated formations («Kernel Holding», «Myronivsky Hliboproduct» and «Astarta Holding»), it is substantiated that the result of the implementation of the proposed strategy for the development of inter-sectoral integration will be a synergistic effect, which is defined as an increase in the efficiency of integrated formations as a result of the association of individual parts into a single system.

description: Fish from catching has an important role in international fisheries as well as in developing countries like India. Therefore maintain good quality in fish raw material is necessary. This poster focuses on how to handle and preserve the fish. Fish processing can be subdivided into fish handling, which is preliminary processing of raw fish, and the manufacture of fish products. Another natural subdivision is into primary processing involved in the filleting and freezing of fresh fish for onward distribution to fresh fish retail and catering outlets, and the secondary processing that produces chilled, frozen and canned products for the retail and catering trades. Ancient methods of preserving fish included drying, salting, pickling and smoking. All of these techniques are still used today but the more modern techniques of freezing and canning have taken on a large importance. The fishery industry is subjected to challenges of seafood safety and quality assurance due to differences in food standards within and between countries. An overview of the fish processing sector gives an insight into the shortcomings of the industry. The legal framework, competent authority and the quality control system in place. There is need for a conceptual change traditional quality assurance system to modern food safety and quality assurance methods.

description: Precision spectroscopy of the Muonium Lamb shift and fine structure requires a robust source of 2S Muonium. To date, the beam-foil technique is the only demonstrated method for creating such a beam in vacuum. Previous experiments using this technique were statistics limited, and new measurements would benefit tremendously from the efficient 2S production at a low energy muon ($<20$ keV) facility. Such a source of abundant low energy $\mathrm{μ^+}$ has only become available in recent years, e.g. at the Low-Energy Muon beamline at the Paul Scherrer Institute. Using this source, we report on the successful creation of an intense, directed beam of metastable Muonium. We find that even though the theoretical Muonium fraction is maximal in the low energy range of $2-5$ keV, scattering by the foil and transport characteristics of the beamline favor slightly higher $\mathrm{μ^+}$ energies of $7-10$ keV. We estimate that an event detection rate of a few events per second for a future Lamb shift measurement is feasible, enabling an increase in precision by two orders of magnitude over previous determinations.

description: Many countries strongly support electric propulsion for various fields of transportation, be it people or goods on land, at sea or in the air. Although electric drive systems appear much simpler than (internal) combustion systems, they exhibit their own challenging development tasks. This becomes obvious when an ever-increasing efficiency, performance or production rate is required, just to name a few. The new challenges can be tackled with the help of new electromagnetic manufacturing processes. High speed processes with their well-known unique capabilities offer promising approaches. However, development is required in order to deliver the required performance. High-speed forming with electromagnetic tools allows the production of sharp-edged battery housings. For body panels, sharp edges are mainly a design feature. For batteries, however, sharp edges allow for an almost ideally rectangular housing, enabling a higher energy density. Increases in the range of up to 10 % are achievable. When it comes to packaging, the liquid cooling and heating of battery packs is of equally large importance. The channels for the medium must not consume too much space. The integration of channels inside the aluminium or steel frame of the battery pack is a promising approach. Due to the high welding speeds of up to 500 mm per second at optimum conditions and at the same time the ability to weld aluminium to aluminium or even steel without any loss in strength, electromagnetic pulse welding offers a promising solution. The conduction of high electrical currents with for example the strong demand to save weight and thus use as little material as possible also requires new processes. Electromagnetic pulse welding of aluminium to aluminium and aluminium to copper is well known, investigated and already used in mass production. However, this is suitable for bus bars only. The connection of terminals to cables is mostly done by crimping. Using a pulsed force for crimping improves the compaction and thus the resistance of the joint, especially of cables with large cross sections. This allows for smaller connectors and reduced cable cross sections.
Understanding the propagation of excitations in quantum spin chains with different kind of interactions

description: The dynamical behaviour of the quantum state of different quantum spin chains, with designed site dependent interaction strengths, is analyzed when the initial state belongs to the one excitation subspace. It is shown that the inhomogeneous chains are able to transfer excitations with near perfect fidelity. This behaviour is found for two very different spin chain Hamiltonians. The first one is the ferromagnetic Heisenberg Hamiltonian with nearest neighbor interactions, the second one describes a chain with long range anisotropic interactions which are ferromagnetic in the $z$ direction and antiferromagnetic in the $(x,y)$ plane. It is shown that both designed chains have in common a partially ordered spectrum and well localized eigenvectors. This physical trait unifies the description of both kind of systems.

description: Purpose. The purpose of the article is to substantiate the factors of organizational support for the creation of added value of agricultural products and to draw up proposals for improving this process at the local level of the agrarian sector (in rural areas). Methodology / approach. The methodological basis of the research is the fundamental provisions of economic theory, scientific concepts and paradigms, and the postulates of the world's science-based value added schools. Research methods: abstract-logical – to summarize the concepts of added value of agricultural products, graphic – to reflect the model of a cooperative organization of creation of added value, methods of analysis and synthesis – to identify the essential features of the study of the process of creating value added and its organizational support. Results. The problems of absence of effective organizational mechanisms for creation of added value of agro-food products are revealed, the factors of organizational support of this process are substantiated, perspective forms of its organization are offered. Originality / scientific novelty. Based on the consideration of multivector approaches to the creation of added value of agro-food products, evolutionary factors have been identified, which determined the modern interpretation of this process. Co-operation was proposed as a perspective form of organization of creation of added value at the local level of the agrarian sector (in rural areas) and a graphic model of this co-operative organization was constructed. Practical value / implications. The significance of the research is determined by the prospects of theoretical and methodological and applied support for the organization of the creation of added value of agri-food products in particular, at the local level of the agrarian sector (in rural areas), using the cooperative model of this organization with the prospect of forming agro-food network organizations.
