description: We consider dynamics of a free relativistic particle at very short distances, treating space-time as archimedean as well as nonarchimedean one. Usual action for the relativistic particle is nonlinear. Meanwhile, in the real case, that system may be treated like a system with quadratic (Hamiltonian) constraint. We perform similar procedure in -adic case, as the simplest example of a nonarchimedean space. The existence of the simplest vacuum state is considered and corresponding Green function is calculated. Similarities and differences between obtained results on both spaces are examined and possible physical implications are discussed.

description: An understanding of the process by which consumers match consumption choices to personal values is powerful aid to guide strategic market orientation. It is of particular importance in the highly saturated food markets of developed countries, where consumer needs are shifting closer and closer towards the search for quality and emotional benefits. This study sets out to explore variation in the consumer choice structure in relation to three products with different levels of search, experience and credence attributes, using means-end chain theory. The results suggest the presence of an emotional component in foods that increases in complexity (becomes more abstract) with the number of credence attributes associated with the product; a fact worthy of the consideration of product managers when designing marketing strategies.

description: The recently identified possibility of ground-state cooling of a mechanical oscillator in the unresolved sideband regime by combination of the dissipative and dispersive optomechanical coupling under the red sideband excitation [Phys. Rev. A 88, 023850 (2013)], is currently viewed as a remarkable finding. We present a comprehensive analysis of this protocol, which reveals its very high sensitivity to small imperfections such as an additional dissipation, the inaccuracy of the optimized experimental settings, and the inaccuracy of the theoretical framework adopted. The impact of these imperfections on the cooling limit is quantitatively assessed. A very strong effect on the cooling limit is found from the internal cavity decay rate which even being small compared with the detection rate may drastically push that limit up, questioning the possibility of the ground state cooling. Specifically, the internal loss can only be neglected if the ratio of the internal decay rate to the detection rate is much smaller than the ratio of the cooling limit predicted by the protocol to the common dispersive-coupling assisted sideband cooling limit. More over, we establish that the condition of applicability of theory of that protocol is the requirement that the latter ratio is much smaller than one. A detailed comparison of the cooling protocol in question with the dispersive-coupling-assisted protocols which use the red sideband excitation or feedback is presented.

description: Knowledge of the relative importance of genetic versus environmental determinants of major developmental transitions is pertinent to understanding phenotypic evolution. In salmonid fishes, a major developmental transition enables a risky seaward migration that provides access to feed resources. In Atlantic salmon, initiation of the migrant phenotype, and thus age of migrants, is presumably controlled via thresholds of a quantitative liability, approximated by body size expressed long before the migration. However, how well size approximates liability, both genetically and environmentally, remains uncertain. We studied 32 Atlantic salmon families in two temperatures and feeding regimes (fully fed, temporarily restricted) to completion of migration status at age 1 year. We detected a lower migrant probability in the cold (0.42) than the warm environment (0.76), but no effects of male maturation status or feed restriction. By contrast, body length in late summer predicted migrant probability and its control reduced migrant probability heritability by 50–70%. Furthermore, migrant probability and length showed high heritabilities and between-environment genetic correlations, and were phenotypically highly correlated with stronger genetic than environmental contributions. Altogether, quantitative estimates for the genetic and environmental effects predicting the migrant phenotype indicate, for a given temperature, a larger importance of genetic than environmental size effects.

description: In this paper we study the combined effects of size and shape of small solid state particles on the absorption, emission and scattering characteristics. We use the statistical approach to calculate these optical properties. In this approach the average optical properties of an ensemble of particles in random orientation are represented by the average optical properties of an ensemble of simple shapes. The validity of this approach is studied in detail for a uniform distribution of hollow spheres where the fractional volume of the central inclusion is varied. We apply the results to two different areas of interest, i) infrared spectroscopy and ii) polarization of scattered light. The effects of particle size and shape on the optical characteristics are discussed. We compare the results using the distribution of hollow spheres with those obtained by using randomly oriented spheroids. Also we compare the results with observations and laboratory measurements. The distribution of hollow spheres is very successful in reproducing laboratory measurements of the scattering angle distribution of the degree of linear polarization for incident unpolarized light of randomly oriented irregular quartz particles. Furthermore, we show that we are able to derive the size distribution of dust grains by fitting the measured degree of linear polarization using computational result for hollow spheres. It is shown that the distribution of hollow spheres is a powerful tool for studying light scattering, absorption and emission by cosmic dust grains and in particular when large numbers of particle parameters need to be considered since the computational demand of the distribution of hollow spheres is small.

description: NGC 663 is a young, moderately rich open cluster, known to contain one of the largest fractions of Be stars among all galactic clusters. In this work we present CCD uvby-beta photometry for stars in its central area. We have used these data to obtain the main cluster physical parameters. We find that the reddening is highly variable, with values ranging from E(b-y)=0.639+/-0.032 in the central part to E(b-y)=0.555+/-0.038 in the south-east. The distance modulus is found to be 11.6+/-0.1 mag.(2.1 Kpc), and the age log t=7.4+/-0.1 years (25+7/-5 Myr). The age obtained is consistent with the interpretation of the Be phenomenon as an evolutionary effect.

description: The slope of the radial distribution function at contact is investigated for a pure component two-dimensional hard disk fluid. Using the framework of scaled particle theory (SPT), an exact equation for g'(σ+) is derived in terms of SPT quantities. This new expression requires the value of the average of a three-particle correlation function g¯for which an ideal gas approximation is developed. The resultant predictions for g'(σ+) are compared to those generated from literature equations and to simulation data generated for this work. In addition to simulation data for g'(σ+), simulation values for the three-particle correlation function g¯ are presented for comparison to the approximation. The simple fourth-order integer coefficient polynomial is an accurate predictor of g'(σ+), on the order of or better than what is calculated by existing equations.

description: The Loschmidt amplitude of the purified states of mixed-state density matrices is shown to have zeros when the system undergoes a quasistatic, quench, or Uhlmann process. While the Loschmidt-amplitude zero of a quench process corresponds to a dynamical quantum phase transition (DQPT) accompanied by the diverging dynamical free energy, the Loschmidt-amplitude zero of the Uhlmann process corresponds to a topological phase transition (TQPT) accompanied by a jump of the Uhlmann phase. Although the density matrix remains intact in a quasistatic process, the Loschmidt amplitude can have zeros not associated with a phase transition. We present examples of two-level and three-level systems exhibiting finite- or infinite- temperature DQPTs and finite-temperature TQPTs associated with the Loschmidt-amplitude zeros. Moreover, the dynamical phase or geometrical phase of mixed states can be extracted from the Loschmidt amplitude. Those phases may become quantized or exhibit discontinuity at the Loschmidt-amplitude zeros. A spinor representation of the purified states of a general two-level system is presented to offer more insights into the change of purification in different processes. The quasistatic process, for example, is shown to cause a rotation of the spinor.

description: Atomic radius plays a key role in the realm of science to understand atomic/molecular physico-chemical properties. Looking at the enormous potential this descriptor has, a model is proposed for absolute radius (r) in terms of electrophilicity index (ω). Atomic radii for 103 elements of the periodic table are reported. Considering the periodic relationship between absolute radius and atomic electrophilicity, this empirical model is proposed invoking regression analysis. The computed radii obey sine qua non of periodic properties. Relativistic effects are also distinct in the newly computed radii. On comparison, the computed data is noted to be in close conformity with the reported radii. Further, some size-dependent properties are calculated by employing the computed absolute radius. These present a substantial periodic behaviour and association with absolute radii.

description: For the interactions between a He($2 ^3S$) atom and a He($2 ^3P$) atom for like isotopes, we report perturbation theoretic calculations using accurate variational wave functions in Hylleraas coordinates of the coefficients determining the potential energies at large internuclear separations. We evaluate the coefficient $C_{3}$ of the first order resonant dipole-dipole energy and the van der Waals coefficients $C_{6}$, $C_{8}$, and $C_{10}$ for the second order energies arising from the mutual perturbations of instantaneous electric dipole, quadrupole, and octupole interactions. We also evaluate the coefficient $C_{9}$ of the leading contribution to the third order energy. We establish definitive values including treatment of the finite nuclear mass for the ${}^3$He($2 ^3S$)--${}^3$He($2 ^3P$) and ${}^4$He($2 ^3S$)--${}^4$He($2 ^3P$) interactions.

description: Introduction: Acute viral hepatitis A is a self-limiting liver infection caused by the hepatitis A virus (HAV). Although most pediatric cases are benign, some children may develop severe complications, including hypokalaemia, thrombocytopenia, respiratory alkalosis, and ascites. Prompt recognition and management of these complications are essential to improving outcomes. This case report discusses a 15-month-old child with acute viral hepatitis A who presented with these complications, highlighting the importance of early intervention.Case Report: A 15-month-old boy was admitted to the Pediatric Intensive Care Unit (PICU) with a 3-day history of jaundice, vomiting, and bradycardia. Laboratory tests revealed severe hypokalaemia (K⁺ = 2.84 mmol/L), deranged liver function tests, and thrombocytopenia. The patient was treated with intravenous fluids, potassium correction, broad-spectrum antibiotics, and supportive care. Imaging confirmed mild ascites, gallbladder wall edema, and splenomegaly. HAV infection was confirmed serologically (IgM positive). Over the next 48 hours, his condition improved, with the resolution of bradycardia, stabilization of electrolytes, and normalization of liver function. He was discharged after 8 days in stable condition, with follow-up planned for nutritional support and further liver monitoring.

Conclusion: This case illustrates the potential for complications such as hypokalaemia, thrombocytopenia, respiratory alkalosis, and ascites in pediatric patients with hepatitis A. Early identification and comprehensive supportive care can lead to favourable outcomes. Similar cases emphasize the need for careful monitoring and prompt intervention to prevent severe consequences in children with acute viral hepatitis A.

description: In this paper we intend to analyse a number of agricultural documents to see if they mesh with the EU’s sustainable development policy. The documents in question were prepared at different times and involved different organizations which reflected the interests of various social and economic stakeholders. After demonstrating the still existing conflict between the Lisbon and the Gothenburg Strategy, we will summarize the thematic strategies concerning EU agriculture. The relationship between agricultural policy and the two basic strategies may have implications for other sectoral strategies (e.g. energy, transport, tourism). If the EU is subsequently able to make headway regarding its strategies, it will also facilitate resolution of this problem at the national strategy level. We will review how the documents’ content concurs or differs regarding the EU’s sustainable development strategy. Finally we will analyse the factors causing the differences and the contradictions and suggest conditions leading to harmony.
Iris : an integrated circuit layout automatic generator

Publisher: name: University of British Columbia
Year: 2009

description: In integrated circuit design, layout generation is tedious, time-consuming and error-prone. Motivated by seeking an alternative to manual layout design, I implmented a CAD tool, Iris, dedicating to layout generation automation. By using Iris, the designer describes the circuit netlist and relative placement of each transistor and signal in the high level language Java. Iris works out the details of every design stage and produces the final layout. Experimental results show that Iris generates layouts which are comparable to manual layouts with much less effort by the designer.

description: We study spin dynamics of excitons confined in self-assembled CdSe quantum dots by means of optical orientation in magnetic field. At zero field the exciton emission from QDs populated via LO phonon-assisted absorption shows a circular polarization of 14%. The polarization degree of the excitonic emission increases dramatically when a magnetic field is applied. Using a simple model, we extract the exciton spin relaxation times of 100 ps and 2.2 ns in the absence and presence of magnetic field, respectively. With increasing temperature the polarization of the QD emission gradually decreases. Remarkably, the activation energy which describes this decay is independent of the external magnetic field, and, therefore, of the degeneracy of the exciton levels in QDs. This observation implies that the temperature-induced enhancement of the exciton spin relaxation is insensitive to the energy level degeneracy and can be attributed to the same excited state distribution.

description: In this paper we analyse price transmission for the carrot, parsley, tomato, green pepper and potato markets. Although there is a dual farm structure dominated by small individual farms, our results imply that price information flows from the producer to the retail level for potatoes, parsley and carrots. Our results also suggest that farmers do not merely accept prices, but can actually influence market prices. Tomato and green pepper prices have large transmission elasticities, and causality runs from the retail to producer level. It therefore follows that tomato and green pepper producers tend to accept prices and that the sector’s prices are determined by upper market levels (processors, wholesalers, retailers). These results are reinforced by the fact that vegetable producers sell a large share of their production through procurement and processing, and therefore are more dependent on the upstream industries, and thus cannot influence prices. For all vegetables in this study the short-run price transmission is symmetric while on the tomato market the long-run price transmission is asymmetric. Results indicate that the tomato market is not competitive and efficient; therefore processors, wholesalers, and retailers are capable of exercising market power, and can instantly transmit producer price increases while just slowly and partially transmitting producer price decreases.

description: We study a neutrino mass texture which can explain the neutrino oscillation data and also saturate the upper bound of the CP asymmetry $ε_1$ in the leptogenesis. We consider the thermal and non-thermal leptogenesis based on the right-handed neutrino decay in this model. A lower bound of the reheating temperature required for the explanation of the baryon number asymmetry is estimated as $O(10^8)$GeV for the thermal leptogenesis and $O(10^{6})$GeV for the non-thermal one.It can be lower than the upper bound of the reheating temperature imposed by the cosmological gravitino problem. An example of the construction of the discussed texture is also presented.

description: Price transmission studies related to the cointegration of price time series are a suitable means for studying market dominance at the various market levels in the food product chains. For this study a price transmission asymmetry study was carried out for 18 commercial food product chains. In this study a monthly price time series was used for the period 2001 to 2005. It was found that there is significant product variation in market dominance which spans the entire industry. However, the variation is not significantly linked to either sectors or vertical levels. At times it is unstable and can easily tilt toward the vertical partner level. Depending on price changes, it can also vary, which, in turn, reflects changes in weather conditions. Following a radical change in prices, there is almost never enough time to achieve full price restoration before the onset of another price shock. The fact that prices are not fully restored may partly explain the continuing value divergence of agricultural prices.

Subjects: subject: Geometric Topology (math.GT)

description: In this paper, we introduce a new nontrivial filtration, called F-order, for classical and virtual knot invariants; this filtration produces filtered knot invariants, which are called finite type invariants similar to Vassiliev knot invariants. Finite type invariants introduced by Goussarov, Polyak, and Viro are well-known, and we call them finite type invariants of GPV-order. We show that for any positive integer $n$ and for any classical knot $K$, there exist infinitely many of nontrivial classical knots, all of whose finite type invariants of GPV-order $< n$, coincide with those of $K$ (Theorem 1). Further, we show that for any positive integer n, there exists a nontrivial virtual knot whose finite type invariants of our F-order $< n$ coincide with those of the trivial knot (Theorem 2). In order to prove Theorem 1 (Theorem 2, resp.), we define an n-triviality via a certain unknotting operation, called virtualization (forbidden moves, resp.), and for any positive integer n, find an n-trivial classical knot (virtual knot, resp.).

description: Bioassay-guided isolation of a dihydroxy flavone from the cell extract of Penicillium EU0013 was carried out using preparative LCMS and the structure was interpreted using 1D and 2D NMR spectra. The fungus was fermented in three different nutrient media i.e. Glucose Nutrient Broth, Glucose Peptone Yeast Broth, and Yeast Extract Broth and the cell extract was obtained using organics. Comparative LCMS profiles of the fungus confirmed the enhanced production of dihydroxy flavone in GPYB media. In this study, the pathogenicity of the dihydroxy flavone is reported for the first time against Fusarium oxysporum f.sp. lycopersici, wilt causing pathogen of a tomato plant. In MIC experiments, the compound inhibited the pathogen at 80 µg mL−1. Molecular docking studies of the compound with Fol tomatinase showed five binding interactions. These docking studies may help explore dihydroxy flavones as a lead for developing new fungicides to prevent wilt disease in tomatoes.

description: It is shown that the Born–Oppenheimer–Huang non-adiabatic coupling terms (NACTs) in a molecular Hamiltonian can be considered as equivalent to a friction force in classical mechanics and consequently responsible for the formation of triatomic species like HeH2+. The classical equation of motion is solved accordingly for a test case of a helium atom approaching an H2+ molecule at its potential minimum along the collinear axis and lines parallel to it and also for the C2v geometry. It is shown that the singular NACTs between the first two excited states slow down the motion of the three quasi-ions (He, H, H)+ while approaching each other and result in substantial loss of kinetic energy in the collision process. These results have profound implications for the formation of di- and triatomic species in the early universe, during the chemical synthesis epoch following the nucleosynthesis that followed the Big Bang.

description: We propose an optical scheme to generate an entangled state between a trapped ion and a solid state donor qubit through which-path erasure of identical photons emitted from the two systems. The proposed scheme leverages the similar transition frequencies between In donor bound excitons in ZnO and the $^2P_{1/2}$ to $^2S_{1/2}$ transition in Yb$^+$. The lifetime of the relevant ionic state is longer than that of the ZnO system by a factor of 6, leading to a mismatch in the temporal profiles of emitted photons. A detuned cavity-assisted Raman scheme weakly excites the donor with a shaped laser pulse to generate photons with 0.99 temporal overlap to the Yb$^+$ emission and partially shift the emission of the defect toward the Yb$^+$ transition. The remaining photon shift is accomplished via the dc Stark effect. We show that an entanglement rate of 21 kHz and entanglement fidelity of 94 % can be attained using a weak excitation scheme with reasonable parameters.

description: In the present study various product development trends in the food industry are reviewed with the main focus on convenience, organic and functional foods. Also highlighted are differences between the U.S. and Europe in terms of consumer habits and food supply trends. Through exploring the reasons behind differences in the extent of product innovation, the author illustrates the different role convenience products have in the US and European markets. Also revealed is the relationship linking convenience products, gluttony, and obesity. In the USA a third generation of convenience products has already appeared with the dual aim of delivering convenience and health. Although in Europe consumption “philosophy” accepts the importance of convenience, greater emphasis is placed on natural origin, freshness and traditional recipes.

description: We discuss proton decay in a recently proposed model of supersymmetric hybrid inflation based on the gauge symmetry $SU(4)_c \times SU(2)_L \times SU(2)_R$. A $U(1)\, R$ symmetry plays an essential role in realizing inflation as well as in eliminating some undesirable baryon number violating operators. Proton decay is primarily mediated by a variety of color triplets from chiral superfields, and it lies in the observable range for a range of intermediate scale masses for the triplets. The decay modes include $p \rightarrow e^{+}(μ^+) + π^0$, $p \rightarrow \barν + π^{+}$, $p \rightarrow K^0 + e^+(μ^{+})$, and $p \rightarrow K^+ + \barν$, with a lifetime estimate of order $10^{34}-10^{36}$ yrs and accessible at Hyper-Kamiokande and future upgrades. The unification at the Grand Unified Theory (GUT) scale $M_{\rm GUT}$ ($\sim 10^{16}$ GeV) of the Minimal Supersymmetric Standard Model (MSSM) gauge couplings is briefly discussed.

description: Colonization of novel habitats can result in marked phenotypic responses to the new environment that include changes in body shape and opportunities for further morphological diversification. Fishes have repeatedly transitioned along the benthic–pelagic axis, with varying degrees of association with the substrate. Previous work focusing on individual lineages shows that these transitions are accompanied by highly predictable changes in body form. Here, we generalize expectations drawn from this literature to study the effects of habitat on body shape diversification across 3344 marine teleost fishes. We compare rates and patterns of evolution in eight linear measurements of body shape among fishes that live in pelagic, demersal and benthic habitats. While average body shape differs between habitats, these differences are subtle compared to the high diversity of shapes found within each habitat. Benthic living increases the rate of body shape evolution and has led to numerous lineages evolving extreme body shapes, including both exceptionally wide bodies and highly elongate, eel-like forms. By contrast, we find that benthic living is associated with the slowest diversification of structures associated with feeding. Though we find that habitat can serve as an impetus for predictable trait changes, we also highlight the diversity of responses in marine teleosts to opportunities presented by major habitats.

description: Phase transitions (PTs) are generally classified into second-order and first-order transitions, each exhibiting different intrinsic properties. For instance, a first-order transition exhibits latent heat and hysteresis when a control parameter is increased and then decreased across a transition point, whereas a second-order transition does not. Recently, hybrid percolation transitions (HPTs) are issued in diverse complex systems, in which the features of first-order and second-order PTs occur at the same transition point. Thus, the question whether hysteresis appears in an HPT arises. Herein, we investigate this fundamental question with a so-called restricted Erdős--Rényi random network model, in which a cluster fragmentation process is additionally proposed. The hysteresis curve of the order parameter was obtained. Depending on when the reverse process is initiated, the shapes of hysteresis curves change, and the critical behavior of the HPT is conserved throughout the forward and reverse processes.

description: We present extreme ultraviolet (XUV) time-resolved photoelectron spectroscopy (TRPES) of an aqueous aniline solution. One-colour XUV-induced photoemission signal of aniline was observed with much greater intensity than expected from its molar fraction in the bulk solution, indicating that aniline is hydrophobically segregated on the liquid surface. The concentration dependence of the photoelectron intensity is found to be well correlated with the surface concentration of aniline estimated by surface tension measurements. Similar segregation was observed also for phenol in aqueous solution. The enhanced surface concentration of aniline makes its XUV-TRPES to be highly vulnerable to the pump-induced space charge effects (PISC). The PISC caused by a moderate pump intensity was not completely corrected using a simple mean field model, and reduction of the pump pulse intensity was necessary. The spectra measured at lower pump intensity were corrected for PISC, which enabled us to extract the information on the excited state dynamics of aniline in aqueous solution under 240 nm photoexcitation. Two components with lifetime on sub-ps and >100 ps timescales were determined, and the former is ascribed to the solvation dynamics in the S1 state after the ultrafast internal conversion from the S3 state and the latter to the subsequent population decay of the S1 state.

description: We propose two schemes to establish entanglement between two mesoscopic quantum systems through a third mesoscopic quantum system. The first scheme entangles two nano-mechanical oscillators in a non-Gaussian entangled state through a Cooper pair box. Entanglement detection of the nano-mechanical oscillators is equivalent to a teleportation experiment in a mesoscopic setting. The second scheme can entangle two Cooper pair box qubits through a nano-mechanical oscillator in a thermal state without using measurements in the presence of arbitrarily strong decoherence.

description: In the Hungarian food economy beer marketing remains something of an enigma. Based on a direct-question survey, focussing mainly on educated younger consumers, this article offers an overview of the most important characteristics of Hungarian beer consumption. It is important to stress that beer consumption is situational, meaning tied to specific consumption situations. Research results prove that logistic regression analysis is a suitable method for determining why consumers opt for specific beverages in specific consumption situations. To analyse targeted marketing, the application of heuristic methods, and decision trees provide a high degree of accuracy. This has proven true for consumers that drink non-alcoholic beers.
