description: We present and discuss a stochastic model of financial assets dynamics based on the idea of an inverse renormalization group strategy. With this strategy we construct the multivariate distributions of elementary returns based on the scaling with time of the probability density of their aggregates. In its simplest version the model is the product of an endogenous auto-regressive component and a random rescaling factor designed to embody also exogenous influences. Mathematical properties like increments' stationarity and ergodicity can be proven. Thanks to the relatively low number of parameters, model calibration can be conveniently based on a method of moments, as exemplified in the case of historical data of the S&P500 index. The calibrated model accounts very well for many stylized facts, like volatility clustering, power law decay of the volatility autocorrelation function, and multiscaling with time of the aggregated return distribution. In agreement with empirical evidence in finance, the dynamics is not invariant under time reversal and, with suitable generalizations, skewness of the return distribution and leverage effects can be included. The analytical tractability of the model opens interesting perspectives for applications, for instance in terms of obtaining closed formulas for derivative pricing. Further important features are: The possibility of making contact, in certain limits, with auto-regressive models widely used in finance; The possibility of partially resolving the long-memory and short-memory components of the volatility, with consistent results when applied to historical series.

description: We present a relativistic chiral mean field (RCMF) model, which is a method for the proper treatment of pion-exchange interaction in the nuclear many-body problem. There the dominant term of the pionic correlation is expressed in two-particle two-hole (2p-2h) states with particle-holes having pionic quantum number, J^{pi}. The charge-and-parity-projected relativistic mean field (CPPRMF) model developed so far treats surface properties of pionic correlation in 2p-2h states with J^{pi} = 0^{-} (spherical ansatz). We extend the CPPRMF model by taking 2p-2h states with higher spin quantum numbers, J^{pi} = 1^{+}, 2^{-}, 3^{+}, ... to describe the full strength of the pionic correlation in the intermediate range (r > 0.5 fm). We apply the RCMF model to the ^{4}He nucleus as a pilot calculation for the study of medium and heavy nuclei. We study the behavior of energy convergence with the pionic quantum number, J^{pi}, and find convergence around J^{pi}_{max} = 6^{-}. We include further the effect of the short-range repulsion in terms of the unitary correlation operator method (UCOM) for the central part of the pion-exchange interaction. The energy contribution of about 50% of the net two-body interaction comes from the tensor part and 20% comes from the spin-spin central part of the pion-exchange interaction.

description: It is widely accepted that the complex dynamics characteristic of recurrent neural circuits contributes in a fundamental manner to brain function. Progress has been slow in understanding and exploiting the computational power of recurrent dynamics for two main reasons: nonlinear recurrent networks often exhibit chaotic behavior and most known learning rules do not work in robust fashion in recurrent networks. Here we address both these problems by demonstrating how random recurrent networks (RRN) that initially exhibit chaotic dynamics can be tuned through a supervised learning rule to generate locally stable neural patterns of activity that are both complex and robust to noise. The outcome is a novel neural network regime that exhibits both transiently stable and chaotic trajectories. We further show that the recurrent learning rule dramatically increases the ability of RRNs to generate complex spatiotemporal motor patterns, and accounts for recent experimental data showing a decrease in neural variability in response to stimulus onset.

description: A model in which a projectile like fragment can be simply regarded as a remnant after removal of some part of the projectile leads to an excited fragment. This excitation energy can be calculated with a Hamiltonian that gives correct nuclear matter binding, compressibility and density distribution in finite nuclei. In heavy ion collisions the model produces a dependence of excitation energy on impact parameter which appears to be correct but the magnitude of the excitation energy falls short. It is argued that dynamic effects left out in the model will increase this magnitude. The model can be directly extended to include dynamics but at the expense of increased computation. For many calculations for observables, a temperature is an easier tool to use rather than an excitation energy. Hence temperature dependences on impact parameter in heavy ion collisions are displayed.

description: Electrification of transportation is an effective way to tackle climate change. Public transportation, such as electric buses, operate on predetermined routes and offer quiet operation, zero local emissions and high energy efficiency. However, the batteries of these buses are expensive and wear out in use. The battery ageing is expedited by fast charging and power spikes during operation. The contribution of this paper is the reduction of the power spikes and thus a prolonged battery lifetime. A novel hybrid energy storage system for electric buses is proposed by introducing a flywheel in addition to the existing battery. A simulation model of the hybrid energy storage system is presented, including a battery ageing model to measure the battery lifetime. The bus was simulated during its daily driving operation on different routes with different energy management strategies and flywheel configurations. These different flywheels as well as the driving cycle had a significant impact on the battery life increase. The proposed hybrid battery/flywheel storage system resulted in a battery lifetime increase of 20% on average.

How color affects food choices

Year: 2009

description: Color has a very strong influence in the hospitality industry. How much thought has been given to food choices because of color, and how influential is that on customers' satisfaction of a food product? Staff that prepares food must understand how color and taste work together through presentation and eye appeal to create the WOW factor since customers eat with their eyes first. People associate different foods with different colors. When this perception changes it often has a detrimental effect on the customer's perception of how that food should taste. Scientific information was gathered on the history of food, the sensory perception of taste, and environmental color design. The information was synthesized to develop a course on how color affects food choices of hospitality foodservice customers. The course will allow students to experience lectures, hands-on taste testing and classroom experimentation. The goal is to help hospitality industry employees develop a better insight into the world of taste. The importance of understanding the effect color has on food choices is paramount to hospitality industry employees. The application of the new found knowledge will allow students to develop a keener sense of why color affects food choices made by hospitality foodservice customers.

description: Quantum key distribution protocols typically make use of a one-way quantum channel to distribute a shared secret string to two distant users. However, protocols exploiting a two-way quantum channel have been proposed as an alternative route to the same goal, with the potential advantage of outperforming one-way protocols. Here we provide a strategy to prove security for two-way quantum key distribution protocols against the most general quantum attack possible by an eavesdropper. We utilize an entropic uncertainty relation, and only a few assumptions need to be made about the devices used in the protocol. We also show that a two-way protocol can outperform comparable one-way protocols.

description: Optimal investment decisions by institutional investors require accurate predictions with respect to the development of stock markets. Motivated by previous research that revealed the unsatisfactory performance of existing stock market prediction models, this study proposes a novel prediction approach. Our proposed system combines Artificial Intelligence (AI) with data from Virtual Investment Communities (VICs) and leverages VICs’ ability to support the process of predicting stock markets. An empirical study with two different models using real data shows the potential of the AI-based system with VICs information as an instrument for stock market predictions. VICs can be a valuable addition but our results indicate that this type of data is only helpful in certain market phases.

description: One of the solutions enabling performance progress, which can overcome the downsizing limit in silicon technology, is the integration of different functional optoelectronic devices within a single chip. Silicon with its indirect band gap has poor optical properties, which is its main drawback. Therefore, a different material has to be used for the on-chip optical interconnections, e.g. a direct band gap III-V compound semiconductor material. In the paper we present the synthesis of single crystalline InP nanodots (NDs) on silicon using combined ion implantation and millisecond flash lamp annealing techniques. The optical and microstructural investigations reveal the growth of high-quality (100)-oriented InP nanocrystals. The current-voltage measurements confirm the formation of an n-p heterojunction between the InP NDs and silicon. The main advantage of our method is its integration with large-scale silicon technology, which allows applying it for Si-based optoelectronic devices.

Adapting Disneyland's service strategy to Korea's Everland theme park
Creators: name: Paik, Haesun
Publisher: name: University of Nevada, Las Vegas
Year: 2010

description: Disneyland is an American amusement park located in Anaheim, California, owned and operated by the Walt Disney Company. On July 18, 1955 the park was first opened to the public (Absolute Astronomy, 2009). Tourists come from all over the world to experience Disneyland not only for theme park, but also for its well-known quality of service, proven time and again by returning visitors. Behind the Disney World being the first, Disneyland is the second most visited park in the world having more than 14,800,000 visitors (TEA and ERA, 2008). Korea is one of the fastest growing countries in Asia and tourists come to Korea with high expectations. However, Korea lacks to have a well-known attraction famous for its customer service that attracts foreign guests. Similar to Disneyland, Korea has its own theme park Everland. Everland was opened in 1976 in Kyonggi-Do, Korea, and is ranked as the 10th theme park in the world having 7,200,000 visitors in 2007 and is known for using their own characters and service strategies (TEA and ERA, 2008). Even though Everland attracts many visitors, it fails to deliver essential customer service and brand recognition. In order to become a well known amusement park, Everland will need to look through Disneyland's service strategy and understand how it attracts more guests, and develop a new service strategy.

description: Critical Gravity in D dimensions is discussed from the point of view of its exact solutions. The special features that certain type of solutions of higher-curvature gravity develop when one approaches the critical point of the parameter space are reviewed. In particular, a non-linear realization of the logarithmic modes of linearized Critical Gravity is seen to emerge as a peculiarity of the sector of anti-de Sitter wave solutions. Logarithmic solutions are shown to occur at a second point of the parameter space, at which the effective mass of the anti-de Sitter waves equals the Breitenlohner-Freedman bound. Other type of solutions with anisotropic scale invariance are also discussed and the special features they develop at the critical point are studied as well. This note is the written version of the talk delivered by one of the authors at the 13th Marcel Grossmann Meeting on general relativity, held in Stockholm, Sweden, in July 2012. The proceeding contribution is based on authors' previous works.

description: This deliverable 4.4 Risk Management is published under WP4 Control and real-time simulation of the construction of the ASHVIN project. Abstract In order to develop comprehensive digital-twin supported site risk management regime it is important to collect data on productivity from well-documented previous construction activities. One of the highest risk activities in construction relates to unknown or unanticipated soil conditions. Soils are naturally occurring, variable materials whose properties depend on stress and strain level and vary temporally. Current design methods deal with uncertainty by assuming conservative estimates of soil properties and calculating the response of the geotechnical structure to some unlikely set of extreme loads. In certain analyses involving soil-structure interaction problems (e.g. soil retaining structures) the loads experienced by structural elements (such as piles, anchors, walls etc.) are directly related to the displacements (strains) experienced. Therefore, only a model that uses the most-likely soil and structure properties at any given point in the life-cycle of a structure to accurately predict the displacement can allow the real safety level (resistance to additional loading) of a structure to be determined.
 This deliverable uses monitoring data collected from the construction of a deep sea quay wall to determine the real safety level of the wall throughout the construction programme. An advanced finite element model is implemented that can capture the real response. By comparing the measured and predicted response of the wall, a number of updates are initiated that incorporate the knowledge gathered and allow for reduction of uncertainty in a logical and consistent manner. The development of Ports is driven by ever increasing vessel sizes. To replace an existing quay wall to allow for larger vessels means an investment of several 100 million euros and a significant environmental cost in terms of CO2 emissions from new construction. In this report the digital twin developed demonstrated the safety level of the existing wall to several metres of additional dredging.

description: We have developed an atom trap trace analysis (ATTA) system to measure Kr in Xe at the part per trillion (ppt) level, a prerequisite for the sensitivity achievable with liquid xenon dark matter detectors beyond the current generation. Since Ar and Kr have similar laser cooling wavelengths, the apparatus has been tested with Ar to avoid contamination prior to measuring Xe samples. A radio-frequency (RF) plasma discharge generates a beam of metastable atoms which is optically collimated, slowed, and trapped using standard magneto-optical techniques. Based on the measured overall system efficiency of $1.2 \times 10^{-8}$ (detection mode) we expect the ATTA system to reach the design goal sensitivity to ppt concentrations of Kr in Xe in $<2$ hours.

description: The question "how small is the lepton mixing angle θ_{13}?" had a convincing answer in a surprisingly short time, θ_{13} \simeq 9^{\circ}, a large value comparable to the Chooz limit. It defines a new epoch in the program of determining the lepton mixing parameters, opening the door to search for lepton CP violation of the Kobayashi-Maskawa-type. I discuss influences of the large value of θ_{13} to search for CP violation and determination of the neutrino mass hierarchy, the remaining unknowns in the standard three-flavor mixing scheme of neutrinos. I emphasize the following two points: (1) Large θ_{13} makes determination of the mass hierarchy easier. It stimulates to invent new ideas and necessitates quantitative reexamination of practical ways to explore it. (2) However, large θ_{13} does not quite make CP measurement easier so that we do need a "guaranteeing machine" to measure CP phase δ.

Immigration and the hospitality industry
Creators: name: Rasic, Joseph M.

description: The purpose of this study is to correlate the research of immigration reform and the potential impact on the hospitality industry. For over a century, numerous debates and policies have been discussed and developed addressing the issue of immigration. The history of immigration policy shows that legislation was passed to address the current concerns for each of the past several decades, but additional changes are constantly needed in order to support the continued growth and changes of the nation. History also shows that some of the laws that were created to control immigration actually initiated larger issues, which led to additional legislation, which left loopholes in the verification process. During the same time frame, the history of the hospitality industry dealt with changes in employment practices in order to comply with the legislation that directed the United States. The hospitality industry has been challenged with finding both skilled and unskilled labor, lowering turnover and making the industry more attractive to potential employees. While facing these employment challenges and changes to immigration policies, the hospitality industry found employment solutions often times through immigrants. With the change in immigrant legislation and employment laws, the industry faced the challenge of not only finding skilled labor, but also ensuring that the employees were legal to work in the United States. One of the more recent forms of legislation that challenges the industry is the implementation of the electronic employment verification system (E-verify). This study will review the implementation of tighter immigrant and employment policies, the continued labor shortage, and the potential cost to the industry.

description: We derive the dynamics of several rigid bodies of arbitrary shape in a 2-dimensional inviscid and incompressible fluid, whose vorticity field is given by point vortices. We adopt the idea of Vankerschaver et al. (2009) to derive the Hamiltonian formulation via symplectic reduction from a canonical Hamiltonian system. The reduced system is described by a non-canonical symplectic form, which has previously been derived for a single, circular disk using heavy differential-geometric machinery in an infinite-dimensional setting. In contrast, our derivation makes use of the fact that the dynamics of the fluid, and thus the point vortex dynamics, is determined from first principles. Using this knowledge we can directly determine the dynamics on the reduced, finite-dimensional phase space, using only classical mechanics. Furthermore, our approach easily handles several bodies of arbitrary shapes. From the Hamiltonian description we derive a Lagrangian formulation, which enables the system for variational time integrators. We briefly describe how to implement such a numerical scheme and simulate different configurations for validation.

description: The nucleon resonances are investigated within a dynamical coupled-channels model of pi N and gamma N reactions up to the invariant mass W = 2 GeV. The meson-baryon (MB) channels included in the calculations are MB = pi N, eta N, K Lambda, K Sigma, and pi pi N that has pi Delta, rho N, and sigma N resonant components. The meson-baryon amplitudes T_{M'B',MB}(W) are calculated from solving a set of coupled-channels integral equations defined by an interaction Hamiltonian consisting of (a) meson-exchange interactions v_{M'B',MB} derived from phenomenological Lagrangian, and (b) vertex interactions N* --> MB for describing the transition of a bare excited nucleon state N* to a channel MB. The parameters of v_{M'B',MB} are mainly constrained by the fit to the data of pi N --> pi N in the low energy region up to W =1.4 GeV. The bare masses of N* and the N* --> MB parameters are then determined in simultaneous fits to the data of pi N --> pi N up to W =2.3 GeV and those of pi N --> eta N, K Lambda, K Sigma and gamma N --> pi N, eta N, K Lambda, K Sigma up to W = 2.1 GeV. The pole positions and residues of nucleon resonances are extracted by analytically continuing the meson-baryon amplitudes T_{M'B',MB}(W) to the complex Riemann energy surface. From the extracted residues, we have determined the N* --> pi N, gamma N, eta N, K Lambda, K Sigma transition amplitudes at resonance poles. We compare the resonance pole positions from our analysis with those given by Particle Data Group and the recent coupled-channels analyses by the Juelich and Bonn-Gatchina groups. Four results agree well only for the first N* in each spin-parity-isospin (J^P,I) channel. For higher mass states, the number of states and their resonance positions from four results do not agree well. We discuss the possible sources of the discrepancies and the need of additional data from new hadron facilities such as J-PARC.

description: We study the notion of recurrence and some of its variations for linear operators acting on Banach spaces. We characterize recurrence for several classes of linear operators such as weighted shifts, composition operators and multiplication operators on classical Banach spaces. We show that on separable complex Hilbert spaces the study of recurrent operators reduces, in many cases, to the study of unitary operators. Finally, we study the notion of product recurrence and state some relevant open questions.

description: A poset can be regarded as a category in which there is at most one morphism between objects, and such that at most one of Hom(c,c') and Hom(c',c) is nonempty for distinct objects c,c'. If we keep in place the latter axiom but allow for more than one morphism between objects, we have a sort of generalized poset in which there are multiplicities attached to covering relations, and possibly nontrivial automorphism groups. We call such a category an "updown category". In this paper we give a precise definition of such categories and develop a theory for them. We also give a detailed account of ten examples, including updown categories of integer partitions, integer compositions, planar rooted trees, and rooted trees.

Nonthermal X-rays from low-energy cosmic rays: Application to the 6.4 keV line emission from the Arches cluster region

description: The iron line at 6.4 keV provides a valuable spectral diagnostic in several fields of X-ray astronomy. It often results from the reprocessing of external X-rays by a neutral or low-ionized medium, but it can also be excited by impacts of low-energy cosmic rays. This paper aims to provide signatures allowing identification of radiation from low-energy cosmic rays in X-ray spectra showing the 6.4 keV line. We study in detail the production of nonthermal line and continuum X-rays by interaction of accelerated electrons and ions with a neutral ambient gas. Corresponding models are then applied to XMM-Newton observations of the X-ray emission emanating from the Arches cluster region near the Galactic center. Bright 6.4 keV line structures are observed around the Arches cluster. This emission is very likely produced by cosmic rays. We find that it can result from the bombardment of molecular gas by energetic ions, but probably not by accelerated electrons. Using a model of X-ray production by cosmic-ray ions, we obtain a best-fit metallicity of the ambient medium of 1.7 plus-minus 0.2 times the solar metallicity. A large flux of low-energy cosmic ray ions could be produced in the ongoing supersonic collision between the star cluster and an adjacent molecular cloud. We find that a particle acceleration efficiency in the resulting shock system of a few percent would give enough power in the cosmic rays to explain the luminosity of the nonthermal X-ray emission. Depending on the unknown shape of the kinetic energy distribution of the fast ions above 1 GeV per nucleon, the Arches cluster region may be a source of high-energy gamma-rays detectable with the Fermi Gamma-ray Space Telescope. At present, the X-ray emission prominent in the 6.4 keV Fe line emanating from the Arches cluster region probably offers the best available signature for a source of low-energy hadronic cosmic rays in the Galaxy.

Applying the service profit chain to the gaming industry, emphasizing on table games dealers, in Las Vegas
Creators: name: Lee, David
Publisher: name: University of Nevada, Las Vegas

description: Gaming has been a significant part of the tourism industry in Las Vegas. Most gamblers come to Las Vegas hoping to win big, but are often disappointed. So what keeps people coming back time and again to contribute to Las Vegas' economy? The casinos and the gaming industry believe that the unique and individual service guests experience at their establishment is the primary reason why guests return. For example, at Harrah's employees are upbeat and positive in an effort to keep customers returning; at the Venetian the core value instilled in each and every employee is to provide un-matched guest services; and for Station Casinos, its customer retention strategy is for employees to provide services beyond guests' expectations.
