description: We investigate the Kondo effect in two-dimensional disordered electron systems using a finite-temperature quantum Monte Carlo method. Depending on the position of a magnetic impurity, the local moment is screened or unscreened by the spin of the conduction electron. On the basis of the results, we show that the distribution of the Kondo temperature becomes wide and the weight at $T_K=0$ becomes large as randomness increases. The average susceptibility shows a weak power-law or logarithmic divergence at low temperature, indicating a non-Fermi-liquid behavior.

description: The Kaluza-Klein theory and Randall-Sundrum theory are examined comparatively, with focus on the behavior of the five dimensional (Dirac) fermion in the dimensional reduction to four dimensions. They are properly treated using the Cartan formalism. In the KK case, the dual property between the electric and magnetic dipole moments is revealed in relation to the ratio of two massive parameters: the inverse of the radius of the extra-space circle and the 5D fermion mass. The order estimation of the couplings is done. In the RS case, we consider the interaction with the 5D(bulk) Higgs field and the gauge field. The chiral property, localization, anomaly phenomena are examined. We evaluate the bulk quantum effect using the method of the induced effective action. The electric dipole moment term naturally appears. This is a new origin of the CP-violation. In the 4D limit, the dual relation between KK model and RS model appears.

description: In the last decade Bovine viral diarrhoea (BVD) was listed by the World Organisation for Animal Health (OIE) as a notifiable disease, due to the fact that it causes significant production losses in cattle industry worldwide. The production losses include reduced milk production, reduced conception rate, abortions, growth retardation, early culling, increased mortality and an increased occurrence of other diseases. This paper presents a possible approach to how an economic analysis of BVD virus, could be conducted at the herd level. For this purpose a spreadsheet model in MS Excel has been developed utilizing Monte Carlo Simulations (MCS). Simulation results show that economic losses at the heard level could exceed 18,000 €. Obtained results suggest that this could be promising approach for analysis BVD effect at herd or animal level.
Dirac neutrino from the breaking of Peccei-Quinn symmetry

description: We propose a model where Dirac neutrino mass is obtained from small vacuum expectation value (VEV) of neutrino-specific Higgs doublet without fine-tuning problem. The small VEV results from a seesaw-like formula with the high energy scale identified as the Peccei-Quinn (PQ) symmetry breaking scale. Axion can be introduced {\it à la} KSVZ or DFSZ. The model suggests neutrino mass, solution to the strong CP problem, and dark matter may be mutually interconnected.

description: We present a method for constructing the complete set of meson-exchange corrections to baryon observables described by covariant chiral quark models. The meson corrections are expressed in terms of an unperturbed valence-quark Green's function. This method is illustrated for the case of an NJL model. It also enables us to discuss, in terms of approximations used for this unperturbed Green's function, the treatments of meson corrections in two other chiral quark models.

description: We discuss the properties of new superconducting compositions of Ru(1-x)Sr2RECu(2+x)O(8-d) (RE=Gd, Eu) ruthenocuprates that were synthesized at 600 atm. of oxygen at 1080 C. By changing ratio between the Ru and Cu, the temperature of superconducting transition (Tc) raises up to Tc max=72 K for x=0.3, 0.4. The hole doping achieved along the series increases with Cu->Ru substitution. For x different than x=0, Tc can be subsequently tuned between Tc max and 0 K by changing oxygen content in the compounds. The magnetic characteristics of the RE=Gd and Eu based compounds are interpreted as indicative of constrained dimensionality of the superconducting phase. Muon spin rotation experiments reveal the presence of the magnetic transitions at low temperatures (Tm=14-2 K for x=0.1-0.4) that can originate in the response of Ru/Cu sublattices. RuSr2Gd(1-y)Ce(1-y)Cu2O8 (0Gd substitution. Properties of these two series allow us to propose phase diagram for 1212-type ruthenocuprates that links their properties to the hole doping achieved in the systems. Non-superconducting single-phase RuSr2GdCu2O8 and RuSr2EuCu2O8 are reported and discussed in the context of the properties of substituted compounds.

description: In developing country production environment, farm production efficiency is often measured in terms of on-farm resources and producer characteristics. In this paper we postulate that input and output market related factors also influence farm production decisions hence its efficiency. Stochastic frontier production function was used to assess technical efficiency and its determinants including input and output market variables for a sample of 1962 pig farms in Vietnam with data collected in 1999. There are significant differences in production behavior and efficiency level between the North and the South, among farms producing different breeds, between mixed and specialized farms, between household and commercial farms, and among producers located in different agro-ecological regions. Access to better output market, land size, herd size, and education of household head significantly reduced inefficiency, while access to government supplied inputs, age of household head, female headed households and family supplied crude feeds significantly increased inefficiency in both the regions. The direction of influence on efficiency differs between the two regions for access to credit, proportion of output sold at market rather than at farm gate and family labor supply. Generally, market related factors had more consistent influence on production efficiency in the South of Vietnam where the experience of market economics is longer compared to the North. Policy actions on providing better extension, more timely access to better quality inputs through the private sector, making credit more easily accessible to smallholders and opportunity to sell output at better priced secondary markets are expected to increase productivity and reduce inefficiency.

description: We discuss the quantization of a scalar particle moving in two-dimensional de Sitter space. We construct the conformal quantum mechanical model on the asymptotic boundary of de Sitter space in the infinite past. We obtain explicit expressions for the generators of the conformal group and calculate the eigenvalues of the Hamiltonian. We also show that two-point correlators are in agreement with the Green function one obtains from the wave equation in the bulk de Sitter space.

description: A density oscillator exhibits limit-cycle oscillations driven by the density difference of the two fluids. We performed two-dimensional hydrodynamic simulations with a simple model, and reproduced the oscillatory flow observed in experiments. As the density difference is increased as a bifurcation parameter, a damped oscillation changes to a limit-cycle oscillation through a supercritical Hopf bifurcation. We estimated the critical density difference at the bifurcation point and confirmed that the period of the oscillation remains finite even around the bifurcation point.

description: Inspired by our previous finding that supersymmetric Yang-Mills-Chern-Simons (SYM-CS) theory dimensionally reduced to 1+1 dimensions possesses approximate Bogomol'nyi-Prasad-Sommerfield (BPS) states, we study the analogous phenomenon in the three-dimensional theory. Approximate BPS states in two dimensions have masses which are nearly independent of the Yang-Mills coupling and proportional to their average number of partons. These states are a reflection of the exactly massless BPS states of the underlying pure SYM theory. In three dimensions we find that this mechanism leads to anomalously light bound states. While the mass scale is still proportional to the average number of partons times the square of the CS coupling, the average number of partons in these bound states changes with the Yang-Mills coupling. Therefore, the masses of these states are not independent of the coupling. Our numerical calculations are done using supersymmetric discrete light-cone quantization (SDLCQ).

description: Hedonic price models were fitted to a sample of 1397 sheep and 1293 goats respectively for which data were collected from nine markets in Ethiopia over a 12 month period. The objective was to determine seasonal and inter-market differences in prices after controlling for the effects of different attributes of the animals, the buyers and the sellers. Results indicate that, controlling for attributes of the animals and of the buyers and sellers, there were significant differences in prices between seasons and markets. Seasons in which farmers faced severe cash shortages exhibited the lowest adjusted prices for animals they sold, indicating that although livestock may provide a fall back position for cash in times of crisis, terms of trade may be worst when farmers need cash the most. In general, there was no clear progression in price of sheep along the primary to terminal market chain ending in Addis Ababa as would be normally expected except that the farthest market had the lowest price. The reason for higher prices in some intermediate terminal markets could be partly explained by the fact that exporters and processors buy animals in these markets and they pay premium prices for best quality animals, and left over second or third grade animals may end up in Addis Ababa market, which then virtually becomes a sink market. In case of goats, price differences between markets followed to some extent the expected differences between primary, secondary and terminal markets. One possible reason is that in general highland is not a major production or consumption area for goats, so supplies come mainly from the lowlands, so the price movement followed the market chain from primary markets in pastoral areas to the terminal market in Addis Ababa.

description: Stochastic frontier production function was used to assess technical efficiency and its determinants for a stratified sample of 1118 poultry farms in Vietnam for which data were collected in 1999. In general there are significant differences in the production behaviour and efficiency level between the North and the South, among farms producing different breeds of poultry, between mixed and specialized poultry farms, between household and commercial farms, and among producers located in different agro-ecological regions. Sale at market place rather than at farm gate, market distance and flock size significantly reduced inefficiency in both the regions. Contract farming or sale, number of visits by extension staff, family labor supply, land size and education of household had significantly reduced inefficiency in the North but had no significant effect in the South. The direction and significance of influence on efficiency differ between the two regions for credit use, inputs from government, ratio of home produced of crude feed, producer age and gender of household head. Therefore, opportunities exist for improving average efficiency through interventions in a number of product and input market domains and household characteristics that may improve access to information, technology and management decisions.

description: We investigate the exclusive photoproduction of a heavy timelike photon which decays into a lepton pair, gamma p -> l+ l- p. This can be seen as the analog of deeply virtual Compton scattering, and we argue that the two processes are complementary for studying generalized parton distributions in the nucleon. In an unpolarized experiment the angular distribution of the leptons readily provides access to the real part of the Compton amplitude. We estimate the possible size of this effect in kinematics where the Compton process should be dominated by quark exchange.

description: An analytical nonadiabatic approach has been developed to study the dimerization gap and the optical absorption coefficient of the Su-Schrieffer-Heeger model where the electrons interact with dispersive quantum phonons. By investigating quantitatively the effects of quantum phonon fluctuations on the gap order and the optical responses in this system, we show that the dimerization gap is much more reduced by the quantum lattice fluctuations than the optical absorption coefficient is. The calculated optical absorption coefficient and the density of states do not have the inverse-square-root singularity, but have a peak above the gap edge and there exist a significant tail below the peak. The peak of optical absorption spectrum is not directly corresponding to the dimerized gap. Our results of the optical absorption coefficient agree well with those of the experiments in both the shape and the peak position of the optical absorption spectrum.

description: Policy analysis matrix (PAM) was applied to assess the competitiveness of local, crossbred and exotic breeds of poultry and pig production in North and South Vietnam using data from a stratified sample of 2,213 farms collected in 1999. Results show that poultry meat and egg production is generally competitive except meat and egg production with local breeds, and egg production with crossbreeds in the North, and egg production with local breeds in the South, due to low productivity and high per unit cost. There are economies of scale in the North but it is not so clear in the South. Domestic prices of both outputs and inputs are higher than the world prices. If output prices fall moderately due to withdrawal of protective policies and domestic demand slows down from the current high levels, poultry breeds that are profitable under the existing situation would still remain competitive. Pig production under existing technologies and market conditions is highly competitive, especially with local and crossbreeds in the North and exotic breeds in the South. Currently the producers in the South are apparently benefiting more due to market conditions and policy that make input cost higher and output price lower in the North. There are economies of scale in pig production. Medium farms are more cost effective, and small farms are least competitive. Unless targeted support is provided to small farms, they are likely to be pushed out of business in a more liberalized economic environment.

description: In this paper, we focused on the use of model calculations to simulate the process of the production and costs of production for cultivation of tomato, cucumber and sweet pepper. With the help of model calculations embedded functional dependencies we tried to find out how three different factors (the price of packaging, manual labor and the size of the market yield) influenced the economics of production. The results of assessment of costs and income have shown us that the selected factors affect economic performance. On the basis of the results, we estimate that model calculations are appropriate tool for evaluation of economics of production, which allow us optimization of production processes.
Quantum Traversal Time Across a Potential Well

description: We consider the quantum traversal time of an incident wave packet across a potential well using the theory of quantum time of arrival (TOA)-operators. This is done by constructing the corresponding TOA-operator across a potential well via quantization. The expectation value of the potential well TOA-operator is compared to the free particle case for the same incident wave packet. The comparison yields a closed-form expression of the quantum well traversal time which explicitly shows the classical contributions of the positive and negative momentum components of the incident wave packet and a purely quantum mechanical contribution significantly dependent on the well depth. An incident Gaussian wave packet is then used as an example. It is shown that for shallow potential wells, the quantum well traversal time approaches the classical traversal time across the well region when the incident wave packet is spatially broad and approaches the expected quantum free particle traversal time when the wave packet is localized. For deep potential wells, the quantum traversal time oscillates from positive to negative implying that the wave packet can be advanced or delayed.

description: Improvement in the precision of measurements of cosmological parameters with Type Ia Supernovae (SNIa) is expected to come from large photometrically identified (photometric) SN samples. Here we re-analyse the SDSS photometric SN sample, with roughly 700 high-quality, likely but unconfirmed SNIa light-curves, to develop new analysis tools aimed at evaluating systematic uncertainties on the dark energy equation-of-state parameter $w$. Since we require a spectroscopically measured host galaxy redshift for each SN, we determine the associated selection efficiency of host galaxies in order to simulate bias corrections. We determine that the mis-association rate of host galaxies is $0.6\%$; ignoring this effect in simulated bias corrections leads to a $w$-bias of $Δw = +0.0007$, where $w$ is evaluated from SNIa and priors from measurements of baryon acoustic oscillations and the cosmic microwave background. We assess the uncertainty in our modeling of the host galaxy selection efficiency and find the associated $w$ uncertainty to be $-0.0072$. Finally, we explore new core collapse (CC) models in simulated training samples and find that adjusting the CC luminosity distribution to be in agreement with previous Pan-STARRS analyses yields a better match to the SDSS data. The impact of ignoring this adjustment is $Δw = -0.0109$; the impact of replacing the new CC models with those used by Pan-STARRS is $Δw = -0.0028$. These systematic uncertainties are subdominant to the statistical constraints from the SDSS sample, but must be considered in future photometric analyses of large SN samples such as those from DES, LSST and WFIRST.

Tachyon mass, c-function and Counting localized degrees of freedom

description: We discuss the localized tachyon condensation in the non-supersymmetric orbifold theories by taking the cosmological constant as the measure of degrees of freedom (d.o.f). We first show asymptotic density of state is not a proper quantity to count the 'localized' d.o.f. We then show that localized d.o.f lead us a c-function given by the lightest tachyon mass, which turns out to be the same as the tachyon potential recently suggested by Dabholkar and Vafa. We also argue that delocalized d.o.f also encode information on the process of localized tachyon condensation in the g-function, based on the fact that the global geometry of the orbifolds is completely determined by the local geometry around the fixed points. For type II, both c- and g-function respect the stability of the supersymmetric models and both allow all the process suggested by Adams, Polchinski and Silverstein.

description: High energy collisions of cosmic ray (CR) nuclei with interstellar gas are believed to be the mechanism producing the majority of CR antiprotons. The distinguishing spectral shape with a maximum at 2 GeV and a sharp decrease towards lower energies makes antiprotons a unique probe of the models of particle propagation in the Galaxy and modulation in the heliosphere. Besides, accurate calculation of the secondary antiproton flux provides a ``background'' for searches for exotic signals from the annihilation of supersymmetric particles and primordial black hole evaporation. Recently new data with large statistics on the antiproton flux have become available which allow for such tests to be performed. We use our 3D Galactic cosmic ray propagation code GALPROP to calculate interstellar propagation in several models. For our best model we make predictions of proton and antiproton fluxes near the Earth for different modulation levels and polarity using a steady-state drift model for heliospheric modulation.

description: High resolution N-body simulations have revealed the survival of considerable substructure within galactic halos. Assuming that the predicted dark matter clumps are composed of annihilating neutralinos, we examine their detectability via Atmospheric Cherenkov Telescopes (ACTs). Depending on their density profile, individual neutralino clumps should be observable via their gamma-ray continuum and line emissions. We find that the continuum signal is the most promising signal for detecting a neutralino clump, being significantly stronger than the monochromatic signals. Limits from the line detectability can help lift degeneracies in the supersymmetric (SUSY) parameter space. We show that by combining the observations of different mass clumps, ACTs can explore most of the SUSY parameter space. ACTs can play a complementary role to accelerator and gamma-ray satellite limits by exploring relatively large neutralino masses and less concentrated clumps. We develop a strategy for dark matter clump studies by future ACTs based on VERITAS specifications and encourage the development of techniques to identify primaries. This can reduce the background by an order of magnitude.

Top quark pair production and decay into 6 fermions at linear colliders

description: The production of a t\bar{t}-pair and its decay into a 6 fermion final state of different flavours in e+e- annihilation at centre of mass energies typical for linear colliders is analyzed in the framework of the Standard Model. The results of calculation based on exact matrix elements at the tree level and full 6 particle phase space are compared with a few different approximations. It is shown that the effects related to off-shellness of the t\bar{t}-pair and background contributions are sizable both in the continuum and at the threshold.

Three Numerical Puzzles and the Top Quark's Chiral Weak-Moment

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

description: Versus the standard model's t --> W b decay helicity amplitudes, three numerical puzzles occur at the 0.1 % level when one considers the amplitudes in the case of an additional (f_M + f_E) coupling of relative strength 53 GeV. The puzzles are theoretical ones which involve the t --> W b decay helicity amplitudes in the two cases, the relative strength of this additional coupling, and the observed masses of these three particles. A deeper analytic realization is obtained for two of them. Equivalent realizations are given for the remaining one. An empirical consequence of these analytic realizations is that it is important to search for effects of a large chiral weak-moment of the top-quark, the effective mass-scale is about 53 GeV. A full theoretical resolution would include relating the origin of such a chiral weak-moment and the mass generation of the top-quark, the W-boson, and probably the b-quark.

description: Resonant energy transfer mechanisms have been observed in the sensitized luminescence of solids, in quantum dots and in molecular nanostructures, and they also play a central role in light harvesting processes in photosynthetic organisms. We demonstrate that such mechanisms, together with the exciton-exciton binding energy shift typical of these nanostructures, can be used to perform universal quantum logic. In particular, we show how to generate controlled exciton entanglement and identify two different regimes of quantum behaviour.

Early dark energy from massive neutrinos -- a natural resolution of the Hubble tension

description: The Hubble tension can be significantly eased if there is an early component of dark energy that becomes active around the time of matter-radiation equality. Early dark energy models suffer from a coincidence problem -- the physics of matter-radiation equality and early dark energy are completely disconnected, so some degree of fine-tuning is needed in order for them to occur nearly simultaneously. In this paper we propose a natural explanation for this coincidence. If the early dark energy scalar couples to neutrinos then it receives a large injection of energy around the time that neutrinos become non-relativistic. This is precisely when their temperature is of order their mass, which, coincidentally, occurs around the time of matter-radiation equality. Neutrino decoupling therefore provides a natural trigger for early dark energy by displacing the field from its minimum just before matter-radiation equality. We discuss various theoretical aspects of this proposal, potential observational signatures, and future directions for its study.
