description: This paper deals with spatial shopping behaviour of consumers in a certain region. An attempt is made to formulate a theoretical framework in such a way that the choice of mathematical representations of variables in the model will become less arbitrarily than is usually the case in this type of models. In this paper a first step is taken to such a theory based on the ideas of Bacon (1971) by assuming that a consumer optimizes an objective function which is more specific than the utility function in logit or probit analysis and which gives us a better opportunity to test the underlying hypothesis. Special attention is given to economic variables. Furthermore the role of distance in the choice problem of the consumer is emphasized, attraction areas of shops are derived from the theory in case of a simplified regional structure, and are compared with those derived from a disaggregate choice model with a logit structure.

description: We present a general method for studying coupled qubits driven by adiabatically changing external parameters. Extended calculations are provided for a two-bit Hamiltonian whose eigenstates can be used as logical states for a quantum CNOT gate. From a numerical analysis of the stationary Schroedinger equation we find a set of parameters suitable for representing CNOT, while from a time-dependent study the conditions for adiabatic evolution are determined. Specializing to a concrete physical system involving SQUIDs, we determine reasonable parameters for experimental purposes. The dissipation for SQUIDs is discussed by fitting experimental data. The low dissipation obtained supports the idea that adiabatic operations could be performed on a time scale shorter than the decoherence time.

description: In this paper we give the optimal maintenance policy of a building where we let the rent depend on the quality of the building. We assume that the quality of the building can be described by a stochastic process on which the maintenance policy has an influence. Furthermore we give rules for when the landlord has to sell the building or when he has to rent it. From these rules it follows that under uncertainty the landlord is more prepared to rent the building than without uncertainty.
title: "The Implications of Metamorphism and Weathering of the Lesser Himalayan Formation in Eastern Nepal for Climate Change"
Creators: name: Oliver, Lee
Publisher: name: The Open University
Year: 2003

description: This study evaluates the significance of Sr-isotopes as a silicate weathering proxy in the context of Himalayan river systems. The dissolved load of the Bhote Kosi (central Nepal) displays a rapid increase in 87Sr/86Sr ratio immediately downstream of the Main Central Thrust, a feature common to other Himalayan tributaries of the Ganges. The results of statistical and mass balance analyses identify the weathering of radiogenic (87Sr/86Sr >0.8) calc-silicate lithologies from the Lesser Himalayan Formation as the predominant control upon the dissolved 87Sr/86Sr ratio.

 In situ laser ablation analysis of dolomite in these calc-silicates yields radiogenic 87Sr/86Sr, indistinguishable from bulk rock ratios, confirming the presence of a highly soluble source of radiogenic strontium. The distribution of Rb-Sr isotopes suggests homogenisation of Sr-fsotopes between silicate and carbonate at both grain-size and bulk-rock scale. Similar lithologies can be traced across much of the southern Himalaya, and multiple regressions from Bhote Kosi data successfully predict dissolved 87Sr/86Sr ratios in other major Himalayan rivers, indicating that findings from the Bhote Kosi are applicable across eastern Nepal.

 Flux calculations indicate that at least 50% of the impact of the Bhote Kosi river on the global marine 87Sr/86Sr ratio can be traced to weathering of Lesser Himalayan carbonates. Hence a significant proportion of the increase in marine 87Sr/86Sr ratio over the past 7-10 Ma is ascribed to the exposure of these lithologies. The widespread assumption that dissolved 87Sr/86Sr ratios are a proxy for silicate weathering rates is therefore undermined where ancient metamorphosed calc-silicate rocks are exposed in river catchments. Although this conclusion casts doubt upon the use of the marine strontium isotope record to quantify carbon dioxide drawdown resultant from present day Himalayan silicate weathering, evidence suggests that prior to uplift of the Lesser Himalaya, dissolved Sr-isotope ratios in Himalayan runoff did provide an indication of silicate weathering rates.

description: With the advent of high-resolution and cost-effective genomics and bioinformatics tools and methods contributing to a large database of both human (HAdV) and simian (SAdV) adenoviruses, a genomics-based re-evaluation of their taxonomy is warranted. Interest in these particular adenoviruses is growing in part due to the applications of both in gene transfer protocols, including gene therapy and vaccines, as well in oncolytic protocols. In particular, the re-evaluation of SAdVs as appropriate vectors in humans is important as zoonosis precludes the assumption that human immune system may be naïve to these vectors. Additionally, as important pathogens, adenoviruses are a model organism system for understanding viral pathogen emergence through zoonosis and anthroponosis, particularly among the primate species, along with recombination, host adaptation, and selection, as evidenced by one long-standing human respiratory pathogen HAdV-4 and a recent re-evaluation of another, HAdV-76. The latter reflects the insights on amphizoonosis, defined as infections in both directions among host species including “other than human”, that are possible with the growing database of nonhuman adenovirus genomes. HAdV-76 is a recombinant that has been isolated from human, chimpanzee, and bonobo hosts. On-going and potential impacts of adenoviruses on public health and translational medicine drive this evaluation of 174 whole genome sequences from HAdVs and SAdVs archived in GenBank. The conclusion is that rather than separate HAdV and SAdV phylogenetic lineages, a single, intertwined tree is observed with all HAdVs and SAdVs forming mixed clades. Therefore, a single designation of “primate adenovirus” (PrAdV) superseding either HAdV and SAdV is proposed, or alternatively, keeping HAdV for human adenovirus but expanding the SAdV nomenclature officially to include host species identification as in ChAdV for chimpanzee adenovirus, GoAdV for gorilla adenovirus, BoAdV for bonobo adenovirus, and ad libitum.

The pipeline industry has undertaken an essential upgrade of well established X70 pipeline steel in heavy gauge pipes to fill the demand of increased operating pressures. A developed welding process, cold wire tandem submerged arc welding (CWTSAW), with improved deposition rate and travel speed can meet this upgrade. Currently, the effect of CWTSAW process parameters and bevel design on the change in weld geometry and properties of the weld and heat-affected zone (HAZ) in heavy gauge X70 pipe is not well understood. In this article, a series of weld trials were conducted on heavy gauge (19.1 mm) X70 steel plates to investigate the effect of cold wire feed speed, heat input and bevel design on the reinforcement size, coarse grained heat-affected zone (CGHAZ) area, ratio of weld shapes and micro-hardness of the weld and HAZ. The results showed that the cold wire feed speed significantly influenced the micro-hardness profiles, and bevel design was the dominant factor influencing the reinforcement size and CGHAZ area. In addition, empirical equations of micro-hardness profiles of the CWTSAW samples were developed using a non-linear regression analysis. The phase fraction and morphology of martensite-austenite (MA) constituents were analyzed using optical microscopy and scanning electron microscopy. The microstructural results indicated lower MA fractions with fine and dispersed MA constituents obtained in the CGHAZ of the CWTSAW samples than for conventional tandem submerged arc welding samples. This can be interpreted as the reason for the lower hardness in the CGHAZ of the CWTSAW samples.
Curious behaviour of the diffusion coefficient and friction force for the strongly inhomogeneous HMF model

description: We present first elements of kinetic theory appropriate to the inhomogeneous phase of the HMF model. In particular, we investigate the case of strongly inhomogeneous distributions for $T\to 0$ and exhibit curious behaviour of the force auto-correlation function and friction coefficient. The temporal correlation function of the force has an oscillatory behaviour which averages to zero over a period. By contrast, the effects of friction accumulate with time and the friction coefficient does not satisfy the Einstein relation. On the contrary, it presents the peculiarity to increase linearly with time. Motivated by this result, we provide analytical solutions of a simplified kinetic equation with a time dependent friction. Analogies with self-gravitating systems and other systems with long-range interactions are also mentioned.

description: Dark plasmonic modes have interesting properties, such as a longer lifetime and a narrower linewidth than their radiative counterpart, as well as little to no radiative losses. However, they have not been extensively studied yet due to their optical inaccessibility. Using electron-energy loss (EEL) and cathodoluminescence (CL) spectroscopy, the dark radial breathing modes (RBMs) in thin, monochrystalline gold nanodisks are systematically investigated in this work. It is found that the RBMs can be detected in a CL set-up despite only collecting the far-field. Their visibility in CL is attributed to the breaking of the mirror symmetry by the high-index substrate, creating an effective dipole moment. The outcoupling into the far-field is demonstrated to be enhanced by a factor of 4 by increasing the thickness of the supporting SiN membrane from 5 to 50 nm due to the increased net electric dipole moment in the substrate. Furthermore, it is shown that the resonance energy of RBMs can be easily tuned by varying the diameter of the nanodisk, making them promising candidates for nanophotonic applications.

description: We obtain the energy and momentum densities of a general static axially symmetric vacuum space-time described by the Weyl metric, using Landau-Lifshitz and Bergmann-Thomson energy-momentum complexes. These two definitions of the energy-momentum complex do not provide the same energy density for the space-time under consideration, while give the same momentum density. We show that, in the case of Curzon metric which is a particular case of the Weyl metric, these two definitions give the same energy only when $R \to \infty$. Furthermore, we compare these results with those obtained using Einstein, Papapetrou and Møller energy momentum complexes.

description: On September 18, 2012, the Pharmaceutical Sciences Building unveiled an Impact Media Wall (IMW) portraying pharmacy's contribution to healthcare in the form of an exhibit called "The Story of Medicines" (SOM). Since its implementation, the IMW has encountered high operational and maintenance costs, namely the constant replacement of projector bulbs and excessive power consumption. Other problems posed by the current media wall include uneven light distribution, restrictive back-end proprietary software, and limitations in display content. Using a triple bottom line analysis, the current IMW installed by NGX Interactive was assessed along with a proposed alternative using Christie MicroTiles, a video display system produced by Christie Digital, an industry leader in digital signage. The investigation on the comparison of these two products is evaluated based on economic, environmental, and social impacts. Data and sources for an analytic investigation was obtained mainly through manufacturers' websites and datasheets, a group of UBC graduate students conducting an ongoing life cycle analysis on the current media wall, and primary data in the form of an unbiased survey. While Christie MicroTiles require a large up-front cost of implementation from an economic standpoint, the overall e ectiveness of the microtile system addresses many of the current issues and presents many unique features, such as touch-screen interactivity. Furthermore, the microtile alternative has appreciably lower recurring annual costs, which would help o set the initial capital costs of the installation. Due to the absence of replaceable consumable parts like bulbs, the operational costs and the total cost of ownership (TCO) is minimized, providing a viable alternative in the long term.

Ultrafast nonlinear dynamics of finite graphene systems
Creators: name: Zafar, Ahmal Jawad
Publisher: name: Georgia State University
Year: 2023

description:
We study theoretically nonlinear dynamics of a graphene nanoflake placed in the field of an ultrashort optical pulse. We describe the graphene system within an effective model with infinite mass boundary conditions. For an optical pulse with a duration of just a few femtoseconds, the electron dynamics is coherent and is described by a time-dependent Schro ?dinger equation. For graphene nanoring, if the optical pulse is circularly polarized, then two valleys of graphene are populated differently, resulting in a finite valley polarization of the system after the pulse. Such valley polarization is a unique property of graphene nanoscale systems, while for a graphene monolayer, a circularly polarized pulse does not produce any valley polarization. The valley polarization of a graphene nanoring depends on the parameters of the system, such as inner and outer radii. With the systems size increasing, the valley polarization monotonically decreases, converging to its zero value for the infinite graphene monolayer. Furthermore, we theoretically study the generation of high harmonics in disk shape graphene quantum dots placed in (i) linearly and (ii) and subsequently, a transition to circularly polarized short pulses. The length gauge was used to describe the interaction of quantum dots with an optical pulse. The generated radiation spectra of graphene quantum dots as a result of a linearly polarized pulse can be controlled by varying the quantum dot size, i.e., its radius. With increasing the quantum dot radius, the intensities of low harmonics mainly decrease, while the cutoff frequency increases. The sensitivity of the cutoff frequency to the QD size increases with the intensity of the pulse. Moreover, the transition from linearly to circularly polarized pulse suppresses the harmonics and cutoff frequency in radiation spectra. The cutoff frequency is independent of the size of a quantum dot when a completely circularly polarized pulse is shined. The cutoff frequency and intensity of harmonics can be tuned by the ellipticity and frequency of the laser pulse.

description: The Mittag-Leffler function is universally acclaimed as the Queen function of fractional calculus. The aim of this work is to survey the key results and applications emerging from the three-parameter generalization of this function, known as the Prabhakar function. Specifically, after reviewing key historical events that led to the discovery and modern development of this peculiar function, we discuss how the latter allows one to introduce an enhanced scheme for fractional calculus. Then, we summarize the progress in the application of this new general framework to physics and renewal processes. We also provide a collection of results on the numerical evaluation of the Prabhakar function.

Studies of Attosecond Time Delay and Superheavy Elements in Atomic Photoionization
Creators: name: Khademhosseini, Rezvan
Publisher: name: Georgia State University
Year: 2023

description:
This research consists of two distinct but related elements in the realm of atomic photoionization. The first was to explore the photoionization in superheavy elements. Employing the fully Relativistic Random Phase Approximation (RRPA), we calculated the photoionization cross sections for the Oganesson (Og), the heaviest element, since the influence of relativity becomes more significant as the atomic number increases. The results revealed the importance of relativistic interactions along with the predominant influence of interchannel coupling on the photoionization cross sections. Encouraged by the ability of the RRPA to deal with the combination of relativistic and many-body correlation effects, we proceeded to investigate the angle-dependent time delay in the photoionization process using the RRPA. Specifically, we investigated the time delay in argon. The matrix elements calculated using RRPA were used to calculate the phases of the various photoionization amplitudes, and the energy derivative of these phases provided us with the time delay information. We computed a weighted average of the time delays associated with dipole and quadrupole components, averaged over photoelectron spin and orientation of the residual ion, considering different transitions involved in the photoionization process. Time delay in photoionization exhibits angular dependence, a phenomenon explored in previous calculations considering only dipole transitions. In the nonrelativistic dipole approximation, time delay for atomic ns-states is angle-independent. However, incorporating relativistic effects, such as spin-flip transitions and non-dipole (quadrupole) effects, introduces angular dependence to the time delay. This is especially prominent when dominant dipole photoionization channels (without spin-flip) vanish at specific angles due to angular momentum geometry. In these instances, quadrupole and spin-flip transitions dominate. When the dipole amplitude vanishes, time delay results from a combination of spin-flip dipole and quadrupole time delays. Relativistic expressions have been formulated to delineate the conditions where quadrupole and/or spin-flip channels influence the time delay. We focus on the 3s subshell in argon to highlight the complex effects of spin-flip and quadrupole transitions. Of particular interest is the presence of a significant Cooper minimum in the cross section, leading to notably long time delays. Our goal is to explore these dynamics and understand the intricate processes in photoionization.

description: In this paper we estimated household cost functions and equivalence scales. Two versions of scales are derived, a general one and a utilityspecific one. The new feature of this paper is the methodology. With respect to method we base ourselves on direct cost assessments by respondents for various welfare levels, derived from attitude questions. We see that respondents are not able to assess the true cost function directly, but that their response behavior reveals a virtual cost function. From their response the true cost function may be derived. The alternative approach used in this paper does not make use of typical consumer surveys. The specific question needed in this paper can be plugged into any type of survey, oral or written. Linked with a few background data on income and family size it serves its purpose. A straightforward generalization of 'this method lies at hand. The same method can be used to develop and estimate equivalence scales for other factors.

description: In this paper we apply Maximum Likelihood and Bayesian methods to explain differences in floorspace productivity among retail establishments in the grocery trade. The model we develop is a switching model where sales are either supply determined or demand determined. Under excess supply the model allows for so-called 'trading-down', i.e., an increase in the share of selling area, and, thereby, a decrease in service level. To estimate our model we employ a cross-section of observations on individual shops. We present maximum likelihood results, and also study the shape of the likelihood surface by means of Monte Carlo numerical integration methods. With a uniform prior we obtain marginal posterior density functions both of the parameters of interest and of the average probability of the excess supply regime in the sample. The average probability of excess supply is .23, with a standard deviation of .06. This shows that, according to our estimates, excess demand is the rule and excess supply the exception in the sample that we analyse.

Such an inequality, which we call the "thermodynamic reverse bound", is compactly expressed as a quantum relative entropy, from which it inherits mathematical properties and meaning. As concrete examples, we apply our bound to evaluate the thermodynamic length for open processes, the heat exchange in erasure processes, and the maximal energy outflow in general quantum evolutions.

description: Objective: The objective of the study is to examine whether children aged 7 to 11 years with very well-characterized ADHD, recruited from the community, have a similar number of healthy lifestyle behaviors as compared with typically developing children from the same community. Method: Parents of children with (n = 184) and without (n = 104) ADHD completed a lifestyle questionnaire asking about water intake, sweetened beverage consumption, multivitamin/supplement use, reading, screen time, physical activity, and sleep. A lifestyle index was formed from these seven domains (0-7), and multivariable ordered logistic regression was used to examine the association of ADHD status and total healthy lifestyle behaviors. Results: Children with ADHD were almost twice as likely to have fewer healthy behaviors, even after adjustment for age, sex, intelligence quotient (IQ), ADHD medication use, household income, and four comorbid psychiatric disorders (odds ratio [OR] [95% confidence interval] = 1.95 [1.16, 3.30], p =.01). Conclusion: Future research is needed to assess the effects of a combined lifestyle intervention in this group.

Two hadron production in e+e- annihilation to next-to-leading order accuracy

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

description: We discuss the production of two hadrons in e+e- annihilation within the framework of perturbative QCD. The cross section for this process is calculated to next-to-leading order accuracy with a selection of variables that allows the consideration of events where the two hadrons are detected in the same jet. In this configuration we contemplate the possibility that the hadrons come from a double fragmentation of a single parton. The double-fragmentation functions required to describe the transition of a parton to two hadrons are also necessary to completely factorize all collinear singularities. We explicitly show that factorization applies to next-to-leading order in the case of two-hadron production.

description: We consider the ground state of vortices in a Bose-Einstein condensate. We show that turning on a weak optical periodic potential leads to a transition from the triangular Abrikosov vortex lattice to phases where the vortices are pinned by the optical potential. We discuss the phase diagram of the system for a two-dimensional optical periodic potential with one vortex per optical lattice cell. We also discuss the influence of a one-dimensional optical periodic potential on the vortex ground state. The latter situation has no analogue in other condensed-matter systems.

description: A flexible numerical integration method is proposed for the computation of moments of a multivariate posterior density with different tail properties in different directions. The method (called mixed integration) amounts to a combination of classical numerical integration and Monte Carlo integration. Mixed integration is parsimonious in the sense that it makes use of the same parameters as the more restrictive multivariate normal importance function. The method is applied in order to compute the posterior scores of three candidates for a professorship in Operations Research taking into account four different decision criteria.

Research Methods/ Statistical Methods

description: The method of maximum likelihood is rather demanding, in the sense that a large number of observations is required in order to prevent the likelihood function from becoming unbounded. In this paper precise conditions are formulated such that the likelihood function associated with the Rotterdam model will be bounded under (a) conditions of homogeneity and symmetry and (b) the negativity condition. In addition it is shown that, surprisingly enough, the number of observations that is required to estimate the linear expenditure system is not smaller than the number that is required to estimate the Rotterdam model.
Mechanical Properties of Thermoplastic Polymers in Fused Filament Fabrication (FFF)

Fused filament fabrication (FFF) is a method used to fabricate initial prototypes out of polymeric materials with printed parts often being used as load carrying elements. The mechanical properties of various polymer materials produced under certain printing conditions exhibit superior strength and ductility and may serve as an inexpensive replacement for metal or wooden parts. To gain knowledge of 3-D printed part strength and compare the quality of filament material from several manufacturers, this study characterizes the mechanical properties of parts printed from various commercial FFF feedstocks. Uniaxial tensile testing is performed to determine the ultimate tensile strength, Youngs modulus and fracture strain, of polymer and composite materials.

Critical dynamics in thin films

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Critical dynamics in film geometry is analyzed within the field-theoretical approach. In particular we consider the case of purely relaxational dynamics (Model A) and Dirichlet boundary conditions, corresponding to the so-called ordinary surface universality class on both confining boundaries. The general scaling properties for the linear response and correlation functions and for dynamic Casimir forces are discussed. Within the Gaussian approximation we determine the analytic expressions for the associated universal scaling functions and study quantitatively in detail their qualitative features as well as their various limiting behaviors close to the bulk critical point. In addition we consider the effects of time-dependent fields on the fluctuation-induced dynamic Casimir force and determine analytically the corresponding universal scaling functions and their asymptotic behaviors for two specific instances of instantaneous perturbations. The universal aspects of nonlinear relaxation from an initially ordered state are also discussed emphasizing the different crossovers that occur during this evolution. The model considered is relevant to the critical dynamics of actual uniaxial ferromagnetic films with symmetry-preserving conditions at the confining surfaces and for Monte Carlo simulations of spin system with Glauber dynamics and free boundary conditions.

description: In autonomous driving, monocular sequences contain lots of information. Monocular depth estimation, camera ego-motion estimation and optical flow estimation in consecutive frames are high-profile concerns recently. By analyzing tasks above, pixels in the middle frame are modeled into three parts: the rigid region, the non-rigid region, and the occluded region. In joint unsupervised training of depth and pose, we can segment the occluded region explicitly. The occlusion information is used in unsupervised learning of depth, pose and optical flow, as the image reconstructed by depth-pose and optical flow will be invalid in occluded regions. A less-than-mean mask is designed to further exclude the mismatched pixels interfered with by motion or illumination change in the training of depth and pose networks. This method is also used to exclude some trivial mismatched pixels in the training of the optical flow network. Maximum normalization is proposed for depth smoothness term to restrain depth degradation in textureless regions. In the occluded region, as depth and camera motion can provide more reliable motion estimation, they can be used to instruct unsupervised learning of optical flow. Our experiments in KITTI dataset demonstrate that the model based on three regions, full and explicit segmentation of the occlusion region, the rigid region, and the non-rigid region with corresponding unsupervised losses can improve performance on three tasks significantly.
