description: We discuss the pion form factor calculation in QCD.We shortly consider the main points of the nonlocal condensate QCD sum rule approach and show its results for the pion form factor, $F_π(Q^2)$. These results are compared with predictions of the perturbative and lattice QCD. Then we consider the Local Duality (LD) approach for the pion FF in QCD and show that for $Q^2\gtrsim 2$ GeV$^2$ the main parameter of the approach, namely, $s_0^{\text{LD}}(Q^2)$ should grow with $Q^2$ rather than be a constant.

description: First-principles density-functional-theory calculations show that compression of alkali metals stabilizes open structures with localized interstitial electrons which may exhibit a Stoner-type instability towards ferromagnetism. We find ferromagnetic phases of the lithium-IV-type, simple cubic, and simple hexagonal structures in the heavier alkali metals, which may be described as s-band ferromagnets. We predict that the most stable phases of potassium at low temperatures and pressures around 20 GPa are ferromagnets.

Numerical investigation of rotating stall in centrifugal compressors
Creators: name: Halawa, Taher Mohammed Abdelhakim Fattouh
Publisher: name: University of British Columbia
Year: 2016

description: Rotating stall is a complicated phenomenon which may occur when a centrifugal compressor works at low flow rate condition close to the compressor surge limit. Rotating stall and surge may cause a large amount of damage to the compressor components due to instability and high pressure fluctuations which increase vibration of the compressor blades. This research introduces numerical simulations of the rotating stall phenomenon in a high speed centrifugal compressor with vaned and vaneless diffusers. The present study discusses the improvement of two important methods to control stall: the air injection method and the casing grooves treatment method. The method of air injection was optimized by monitoring the effects resulting from the variation of the angle of injection and the injection flow rate. The efficiency of the casing grooves method was related to the grooves' locations, cross section dimensions, and the number of grooves. The current research also presents estimations of the deformation of the compressor blades during the transition stage between stall and surge in order to determine whether the blades will deform safely within the tip clearance gap without touching the casing. Rotating stall simulations showed that the initiation of stall is due to the flow separation and the formation of the tip leakage flow. Simulations showed also that stall development appears at the vaneless area between the impeller and diffuser. Air injection simulations showed that stability is optimized when the air injection angle is approximately double the value of the diffuser inlet vane angle. Simulations showed that in order to achieve effective flow circulation, the aspect ratio of the casing groove cross section should be at least equal to one. Structural analysis showed that the most dangerous region at the deformed blade’s tip surface is located at the transition area between the axial and radial blade profile. Results also showed that the deformation of the blades at the tip region can be limited by changing the shaft bearing stiffness; this is useful to prevent damage to the compressor blades.
Dynamical 3-Space Gravity Theory: Effects on Polytropic Solar Models

description: Numerous experiments and observations have confirmed the existence of a dynamical 3-space, detectable directly by light-speed anisotropy experiments, and indirectly by means of novel gravitational effects, such as bore hole g anomalies, predictable black hole masses, flat spiral-galaxy rotation curves, and the expansion of the universe, all without dark matter and dark energy. The dynamics for this 3-space follows from a unique generalisation of Newtonian gravity, once that is cast into a velocity formalism. This new theory of gravity is applied to the sun to compute new density, pressure and temperature profiles, using polytrope modelling of the equation of state for the matter. These results should be applied to a re-analysis of solar neutrino production, and to stellar evolution in general.

description: Pig industry is the basic industry of our national economy. In order to maintain the healthy and stable development of China's pig breeding industry, through in-depth investigation, observation and analysis, this paper points out that there are problems of insufficient and unbalanced development in the current development of China's pig industry. In accordance with the reality of our country, this paper puts forward the remedial methods and measures to maintain the sustained, healthy and stable development of pig breeding. The first is to lay a solid foundation for the nodes of the industrial chain and coordinate the development of production, supply and marketing. The second is to improve the epidemic prevention network of live pigs to ensure the healthy development of the pig industry. The third is to draw a red line of environmental protection and adhere to the green development of the pig industry. The fourth is to improve the social service organization and promote the new development of the pig industry. These methods provide useful thinking for the further development of pig industry.

description: In this paper, we suggest that there are two different individual 2D CFTs holographically dual to the Kerr-Newman black hole, coming from the corresponding two possible limits --- the Kerr/CFT and Reissner-Nordström/CFT correspondences, namely there exist the Kerr-Newman/CFTs dualities. A probe scalar field at low frequencies turns out can exhibit two different 2D conformal symmetries (named by $J$- and $Q$-pictures, respectively) in its equation of motion when the associated parameters are suitably specified. These twofold dualities are supported by the matchings of entropies, absorption cross sections and real time correlators computed from both the gravity and the CFT sides. Our results lead to a fascinating "microscopic no hair conjecture" --- for each macroscopic hair parameter, in additional to the mass of a black hole in the Einstein-Maxwell theory, there should exist an associated holographic CFT$_2$ description.

description: ABSTRACT: The demonstration that human decision making can systematically violate the laws of rationality has had wide ranging impact on the fields of economics and psychology. However, the cognitive processes that give rise to irrational biases are still poorly understood. In this study, we use a pupillary index to arbitrate between two predominant existing hypotheses – the hypothesis that biases result from fast effortless processing and the hypothesis that biases result from more extensive integration. While effortless processing is associated with smaller pupillary responses, more extensive integration has been shown to be associated with larger pupillary responses. Thus, we test the relationship between pupil responses and choice behavior on six different foundational decision-making tasks classically used to demonstrate irrational biases.

description: The fusion excitation function is the important quantity in planning experiments for the synthesis of superheavy elements. Its values seem to be determined by the experimental study of the hindrance to complete fusion by the observation of mass, angular and energy distributions of the fissionlike fragments. There is ambiguity in establishment of the reaction mechanism leading to the observed binary fissionlike fragments. The fissionlike fragments can be produced in the quasifission, fast fission, and fusion-fission processes which have overlapping in the mass (angular, kinetic energy) distributions of fragments. The branching ratio between quasifission and complete fusion strongly depends on the characteristics of the entrance channel. In this paper we consider a wide set of reactions (with different mass asymmetry and mass symmetry parameters) with the aim to explain the role played by many quantities on the reaction mechanisms. We also present the results of study of the $^{48}$Ca+$^{249}$Bk reaction used to synthesize superheavy nuclei with Z = 117 by the determination of the evaporation residue cross sections and the effective fission barriers $$ of excited nuclei formed along the de-excitation cascade of the compound nucleus.

description: We devise a new proximity junction configuration where an s-wave superconductivity and the superconductivity of Sr2RuO4 interfere with each other. We reproducibly observe in such a Pb/Ru/Sr2RuO4 junction with a single Pb electrode that the critical current Ic drops sharply just below the bulk Tc of Sr2RuO4 and furthermore increases again below a certain temperature below Tc. In order to explain this extraordinary temperature dependence of Ic, we propose a competition effect involving topologically distinct superconducting phases around Ru inclusions. Thus, such a device may be called a "topological superconducting junction".

description: The first realization of solid state quantum computer was demonstrated recently by using artificial atoms -- transmons in superconducting resonator. Here, we propose a novel architecture of flexible and scalable quantum computer based on a waveguide circuit coupling many quantum nodes of controlled atomic ensembles. For the first time, we found the optimal practically attainable parameters of the atoms and circuit for 100{%} efficiency of quantum memory for multi qubit photon fields and confirmed experimentally the predicted perfect storage. Then we revealed self modes for reversible transfer of qubits between the quantum memory node and arbitrary other nodes. We found a realization of iSWAP gate via direct coupling of two arbitrary nodes with a processing rate accelerated proportionally to number of atoms in the node. A large number of the two-qubit gates can be simultaneously realized in the circuit for implementation of parallel quantum processing. Dynamic coherent elimination procedure of excess quantum state and collective blockade mechanism are proposed for realization of $iSWAP$ and $\sqrt {iSWAP} $ quantum gates.

description: In Cleveland, Ohio, very small foodstores comprised a higher proportion of the stores in the low income area than in the higher income area. Prices were generally higher, variety of products more limited, quality of food assortment poorer, and services more restricted in smaller stores. However, for the same type of store, there were no significant differences in these factors between income areas. About 55 percent of the household shoppers in the low income area appeared reasonably satisfied with the stores where they bought most of their food. Product and service needs as expressed by consumers were basically the same, irrespective of income area. However, residents of the low income area were likely to be less mobile and consequently had to shop at stores within walking distance, which are often smaller stores. Supermarkets located in the low income area tended to be on the periphery of the area and were less accessible to residents than if located more centrally
The geometric phase and the dynamics of quantum phase transition induced by a linear quench

description: We have analysed here the role of the geometric phase in dynamical mechanism of quantum phase transition in the transverse Ising model. We have investigated the system when it is driven at a fixed rate characterized by a quench time $τ_q$ across the critical point from a paramagnetic to ferromagnetic phase. Our argument is based on the fact that the spin fluctuation occurring during the critical slowing down causes random fluctuation in the ground state geometric phase at the critical regime. The correlation function of the random geometric phase determines the excitation probability of the quasiparticles, which are excited during the transition from the inital paramagnetic to the ferromagnetic phase. This helps us to evaluate the number density of the kinks formed during the transition, which is found to scale as $τ_q^{-\frac{1}{2}}$. In addition, we have also estimated the spin-spin correlation at criticality.

description: A monic polynomial with integer coefficients is called intersective if it has no root in the rational numbers, but has a root modulo m for all positive integers m > 1. Equivalently, the polynomial has a root in each p-adic field ℚp. Using three different methods for forming these intersective polynomials, we produce an infinite family with Galois group A₄, an infinite family with Galois group D₅ and classify intersective polynomials with holomorph Galois group ℤ₂e × ℤ*₂e

description: An experiment that confirms the Fresnel drag formalism in RF coaxial cables is reported. The Fresnel `drag' in bulk dielectrics and in optical fibers has previously been well established. An explanation for this formalism is given, and it is shown that there is no actual drag phenomenon, rather that the Fresnel drag effect is merely the consequence of a simplified description of EM scattering within a dielectric in motion wrt the dynamical 3-space. The Fresnel drag effect plays a critical role in the design of various light-speed anisotropy detectors.

We found that five out of 8,812 BCGs are E+A (i.e. post-starburst) galaxies, having the H$δ$~absorption line with an equivalent width $>2.5Å$ and no distinct emission lines in [O II] and H$α$. The E+A features we identified from the BCGs for the first time are not as significant as those in general galaxies, indicating that historically the star formation were not very violent.

description: We study the high frequency price dynamics of traded stocks by a model of returns using a semi-Markov approach. More precisely we assume that the intraday return are described by a discrete time homogeneous semi-Markov process and the overnight returns are modeled by a Markov chain. Based on this assumptions we derived the equations for the first passage time distribution and the volatility autocorreletion function. Theoretical results have been compared with empirical findings from real data. In particular we analyzed high frequency data from the Italian stock market from first of January 2007 until end of December 2010. The semi-Markov hypothesis is also tested through a nonparametric test of hypothesis.

Deflection of coronal rays by remote CMEs: shock wave or magnetic pressure?
Creators: name: Filippov, Boris

Publisher: name: arXiv
Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We analyze five events of the interaction of coronal mass ejections (CMEs) with the remote coronal rays located up to 90^\circ away from the CME as observed by the SOHO/LASCO C2 coronagraph. Using sequences of SOHO/LASCO C2 images, we estimate the kink propagation in the coronal rays during their interaction with the corresponding CMEs ranging from 180 to 920 km/s within the interval of radial distances form 3 R. to 6 R. . We conclude that all studied events do not correspond to the expected pattern of shock wave propagation in the corona. Coronal ray deflection can be interpreted as the influence of the magnetic field of a moving flux rope related to a CME. The motion of a large-scale flux rope away from the Sun creates changes in the structure of surrounding field lines, which are similar to the kink propagation along coronal rays. The retardation of the potential should be taken into account since the flux rope moves at high speed comparable with the Alfven speed.

description: We study the asymptotic interaction between two half-quantized vortices in two-component Bose-Einstein condensates. When two vortices in different components are placed at distance 2R, the leading order of the force between them is found to be (log R/ξ-1/2)/R^3, in contrast to 1/R between vortices placed in the same component. We derive it analytically using the Abrikosov ansatz and the profile functions of the vortices, confirmed numerically with the Gross-Pitaevskii model. We also find that the short-range cutoff of the inter-vortex potential linearly depends on the healing length.

Extra Dimensions, Dilaton and Dark Energy

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

description: In view of the recent observations showing that the universe is accelerating we discuss dilaton and radion stabilization from a phenomenological perspective using perfect fluid sources. One general conclusion we present is that the pressure coefficient along extra dimensions should be -2 if that of the observed dimensions is -1, the latter mimicking a cosmological constant compatible with experimental data. The conditions on the dilaton coupling are similarly strong: we find that if the coupling of the dilaton $ϕ$ to fields other than gravity is of the form $\sqrt{-g}\;e^{(a-2)ϕ}\;\mathcal{L}$ where $\mathcal{L}$ representing all other fields yielding the mentioned fluid, $a$ must be -2 if space-time dimensionality is 10. Within our approach these conditions result taking constant radion and dilaton at the level of the equations of motion. To ameliorate this we also discuss how dynamical stabilization may be achieved with a simple variant in which a dilaton potential is added in the picture where the mentioned constraints are shown to remain.

description: Price analysis was used to determine if the behavior of weekly tomato prices at shipping points and wholesale terminal markets is generally consistent with a competitive marketing system. Results indicated that the winter tomato market in 1966-68 performed in an orderly and competitive manner. Prices were established at different locations that were consistent with marketing costs--transportation, storage, and handling. Prices at all locations in the marketing system were closely correlated. Margins were related to the distance transported and the price of the commodity. Shipping-point prices of tomatoes were inversely related to the supply of produce available. Wholesale terminal market prices directly responded to shifts in shipping-point prices. The marketing system for fresh tomatoes generally performed efficiently in establishing prices that cleared the supply of perishable produce each day and week of the marketing season.
Crystal nucleation and cluster-growth kinetics in a model glass under shear

description: Crystal nucleation and growth processes induced by an externally applied shear strain in a model metallic glass are studied by means of nonequilibrium molecular dynamics simulations, in a range of temperatures. We observe that the nucleation-growth process takes place after a transient, induction regime. The critical cluster size and the lag-time associated with this induction period are determined from a mean first-passage time analysis. The laws that describe the cluster growth process are studied as a function of temperature and strain rate. A theoretical model for crystallization kinetics that includes the time dependence for nucleation and cluster growth is developed within the framework of the Kolmogorov-Johnson-Mehl-Avrami scenario and is compared with the molecular dynamics data. Scalings for the cluster growth laws and for the crystallization kinetics are also proposed and tested. The observed nucleation rates are found to display a nonmonotonic strain rate dependency.

More precisely, it is shown that for solutions to the wave equation \Box_gϕ=0 on the domain of outer communications of the Schwarzschild spacetime manifold (M^n_m, g) (where n >= 3 is the spatial dimension, and m > 0 is the mass of the black hole) the associated energy flux E[ϕ](Σ_τ) through a foliation of hypersurfaces (Σ_τ) (terminating at future null infinity and to the future of the bifurcation sphere) decays, E[ϕ](Σ_τ) <= CD/τ^2, where C is a constant only depending on n and m, and D < \infty is a suitable higher order initial energy on Σ_0; moreover we improve the decay rate for the first order energy to E[\partial_tϕ](Σ_τ^R) <= CD/τ^(4-2δ) for any δ> 0 where Σ_τ^R denotes the hypersurface (Σ_τ) truncated at an arbitrarily large fixed radius R < \infty provided the higher order energy D_δon Σ_0 is finite. We conclude our paper by interpolating between these two results to obtain the pointwise estimate |ϕ|_{Σ_τ^R} <= (C D'_δ) / τ^(3/2-δ). In this work we follow the new physical-space approach to decay for the wave equation of Dafermos and Rodnianski.

Reinterpretation of gluon condensate in dynamics of hadronic constituents

description: We describe an approximate quantum mechanical picture of hadrons in Minkowski space in the context of a renormalization group procedure for effective particles (RGPEP) in a light-front Hamiltonian formulation of QCD. The picture suggests that harmonic oscillator potentials for constituent quarks in lightest mesons and baryons may result from the gluon condensation inside hadrons, rather than from an omnipresent gluon condensate in vacuum. The resulting boost-invariant constituent dynamics at the renormalization group momentum scales comparable with Lambda_QCD, is identified using gauge symmetry and a crude mean-field approximation for gluons. Besides constituent quark models, the resulting picture also resembles models based on AdS/QCD ideas. However, our hypothetical picture significantly differs from the models by the available option for a systematic analysis in QCD, in which the new picture may be treated as a candidate for a first approximation. This option is outlined by embedding our presentation of the crude and simple hadron picture in the context of RGPEP and a brief outlook on hadron phenomenology. Several appendices describe elements of the formalism required for actual calculations in QCD, including an extension of RGPEP beyond perturbation theory.

description: It is the simplest, fastest and effective way to improve the yield level of potato by selecting high quality virus-free seed potato for field production and maintaining the original characters of virus-free minituber. Microtuber is featured by small volume, no pathogen, convenient storage and transportation, which can be induced in summer with high temperature and humidity, and overcome a series of problems such as poor survival rate of transplanted test-tube plantlets, and easy pollution of cutting tips. Therefore, it can replace conventional test-tube plantlets directly for reproduction. Meantime, if minitubers are sown ahead of time using cold frame, the growth stage of potato minituber will avoid the occurrence period of aphids. The use of gauze cover for insect prevention has good effect on maintaining the excellent characters of microtuber. The yield and quality of virus-free potato are greatly improved by means of virus-free culture of shoot tip seedlings, subculture propagation of virus-free seedlings, induction of microtubers by dark culture, cultivation of breeder’s seeds in greenhouse and screenhouse to preserve the characters of potato.

description: Using a combination of isothermal-isobaric Monte Carlo and microcanonical molecular dynamics we investigate the relation between structure and self-diffusion in various phases of a model liquid crystal using the Gay-Berne-Kihara potential. These molecules are confined to a mesoscopic slit-pore with atomically smooth substrate surfaces. As reported recently [see M. G. Mazza {\em et al.}, Phys. Rev. Lett. {\bf 105}, 227802 (2010)], a reentrant nematic (RN) phase may form at sufficiently high pressures/densities. This phase is characterized by a high degree of nematic order and a substantially enhanced self-diffusivity in the direction of the director $\hat{\bm{n}}$ which exceeds that of the lower-density nematic and an intermittent smectic A phase by about an order of magnitude. Here we demonstrate that the unique transport behavior in the RN phase may be linked to a confinement-induced packing effect which causes the formation of supramolecular, string-like conformations. The strings consist of several individual molecules that are capable of travelling in the direction of $\hat{\bm{n}}$ as individual "trains" consisting of chains of molecular "cars". Individual trains run in parallel and may pass each other at sufficiently high pressures.

Techniques for enabling in-system observation-based debug of high-level synthesis circuits on FPGAs
Creators: name: Goeders, Jeffrey
Publisher: name: University of British Columbia
Year: 2016

description: High-level synthesis (HLS) is a rapidly growing design methodology that allows designers to create digital circuits using a software-like specification language. HLS promises to increase the productivity of hardware designers in the face of steadily increasing circuit sizes, and broaden the availability of hardware acceleration, allowing software designers to reap the benefits of hardware implementation. One roadblock to HLS adoption is the lack of an in-system debugging infrastructure. Existing debug technologies are limited to software emulation and cannot be used to find bugs that only occur in the final operating environment. This dissertation investigates techniques for observing HLS circuits, allowing designers to debug the circuit in the context of the original source code, while it executes at-speed in the normal operating environment. This dissertation is comprised of four major contributions toward this goal. First, we develop a debugging framework that provides users with a basic software-like debug experience, including single-stepping, breakpoints and variable inspection. This is accomplished by automatically inserting specialized debug instrumentation into the user’s circuit, allowing an external debugger to observe the circuit. Debugging at-speed is made possible by recording circuit execution in on-chip memories and retrieving the data for offline analysis. The second contribution contains several techniques to optimize this data capture logic. Program analysis is performed to develop circuitry that is tailored to the user’s individual design, capturing a 127x longer execution trace than an embedded logic analyzer. The third contribution presents debugging techniques for multithreaded HLS systems. We develop a technique to observe only user-selected points in the program, allowing the designer to sacrifice complete observability in order to observe specific points over a longer period of execution. We present an algorithm to allow hardware threads to share signal-tracing resources, increasing the captured execution trace by 4x for an eight thread system. The final contribution is a metric to measure observability in HLS circuits. We use the metric to explore trade-offs introduced by recent in-system debugging techniques, and show how different approaches affect the likelihood that variable values will be available to the user, and the duration of execution that can be captured.

description: The e-learning element is the latest feature added to the process of teaching and acquiring foreign languages. However, it seems to be the subject of high-speed changes and reshaping. These complex phenomena are in connection with the rapid technological progress and evolution of the society itself. Hence some challenging questions arise: how should traditional way of learning blend with these new trends and how could the obsolescence factor affecting both textbooks and e-learning be best estimated and dealt with

description: A study of three-pseudoscalar $πK \bar{K}$ and $ππη$ coupled system is made by solving the Faddeev equations within an approach based on unitary chiral dynamics. A resonance with total isospin one and spin-parity $J^π= 0^-$ is found with mass $\sim$ 1400 MeV when the $K \bar{K}$ system gets reorganized as the $f_0(980)$. This resonance is identified with the $π(1300)$ listed by the Particle Data Group. Further, the two-body amplitude which describes the interaction between a $π$ and the $f_0(980)$ is extracted from the study of the $πK\bar K$ and $ππη$ system and is then employed to study the $f_0(980)ππ$ system. As a result, a scalar resonance is found near 1790 MeV which drives the two $ f_0 (980)π$ systems to resonate as the $π(1300)$ while the invariant mass of the two pions falls in the mass region of the scalar $σ(600)$. These findings support the existence of a new $f_0$ resonance near 1790 MeV, as found by the BES and Crystal Barrel collaborations. Our results show that this $f_0(1790)$ is definitely distinct to $f_0(1710)$, the latter of which seems to possess a glueball structure dominantly.
