On the compatibility of nested logit models with utility maximization. A comment
|
Journal of Econometrics
|
Börsch-Supan (1990) gives a sufficient condition for the compatibility of choice probabilities with stochastic utility maximization on an interval. We show that the necessary and sufficient conditions for global compatibility as derived by Daly and Zachary (1979) and McFadden (1981) also apply if the nonrandom components are restricted to a closed interval. Hence, this case gives no further restrictions on the choice probabilities. © 1994.

CP-odd WWZ couplings induced by vector-like quarks
|
European Physical Journal C
|
A minimal extension of the standard model includes extra quarks with charges 2/3 and/or -1/3 whose left-handed and right-handed components are both SU(2) singlets. This model predicts new interactions of the flavor-changing neutral current at the tree level, which also violate CP invariance. We study CP-odd anomalous couplings for the W, W, and Z gauge bosons induced by the new interactions at the one-loop level. These couplings become non-negligible only if both up-type and down-type extra quarks are incorporated. Their form factors are estimated to be maximally of order 10<sup>-5</sup>. Such magnitudes are larger than those predicted in the standard model, though smaller than those in certain other models.

The role of prototyping in executive decision systems
|
Information and Management
|
Prototyping has been widely acclaimed as an effective approach to requirements definition and systems development. It is often claimed to be particularly useful in the development of systems to support executive decision making, which by definition deal with unstructured business problems. Data from 109 top executives and 34 MIS managers from 40 organizations are used to identify executives' problems with information systems and the alternative and complimentary solutions to these problems. Prototyping is rated quite highly by MIS managers as a solution to many executive problems. The benefits of prototyping suggested in the literature are clearly borne out by the study. © 1991.

A constrained least squares approach to the general Gauss-Markov linear model
|
Journal of the American Statistical Association
|
The task of estimating the vector of parameters β in the general Gauss-Markov model (y, Xβ, σ<sup>2</sup>W) with no restrictions on the design matrix X or the covariance matrix σ<sup>2</sup>W is formulated as a constrained linear least squares problem. A BLUE of any estimable function of β is obtained directly by solving this problem. The use of matrix decompositions leads to numerically stable algorithms for computing the solution. The approach is theoretically easy and is shown to be computationally more sound than methods based on generalized inverses. Practical expressions for the desired estimators, their covariance matrices, and an estimator of σ<sup>2</sup>are given. © 1981, Taylor & Francis Group, LLC.

On the Algebraic Construction of Multilevel Transfer Operators
|
Computing (Vienna/New York)
|
The basic idea of our new approach is to determine in a first step for each node those pairs of nodes which allow a good interpolation of the unknowns located at this node. These pairs of neighbor nodes (in some cases only one node) are called parent nodes. This is done by solving a local minimization problem which, in addition, yields the interpolation and restriction coefficients. The construction scheme has been generalized to systems of convection-diffusion-reaction equations using a point-block approach. After these suitable pairs of parent nodes have been determined, the nodes are labeled as C- and F-nodes such that each F-node can be interpolated using one of these suitable pairs of parent nodes and the already computed coefficients. Additionally, a simple heuristic algorithm tries to minimize the number of C-nodes and the number of non-zero entries in the coarse grid matrix. The algorithm has been parallelized and shows mesh size independent convergence for standard model problems. Realistic numerical experiments confirm the efficiency of the presented algorithm.

The chairman assignment problem
|
Discrete Mathematics
|
Suppose k states form a union and every year a union chairman has to be selected in such a way that at any time the accumulated number of chairmen from each state is proportional to its weight. In this paper a simple algorithm for a chairman assignment is given which guarantees a small discrepancy. The situation that not only states form unions, but also unions form federations, etc., with one overall organization is also investigated. © 1980.

Selective Sampling for Example-based Word Sense Disambiguation
|
Computational Linguistics
|
This paper proposes an efficient example sampling method for example-based word sense disambiguation systems. To construct a database of practical size, a considerable overhead for manual sense disambiguation (overhead for supervision) is required. In addition, the time complexity of searching a large-sized database poses a considerable problem (overhead for search). To counter these problems, our method selectively samples a smaller-sized effective subset from a given example set for use in word sense disambiguation. Our method is characterized by the reliance on the notion of training utility: the degree to which each example is informative for future example sampling when used for the training of the system. The system progressively collects examples by selecting those with greatest utility. The paper reports the effectiveness of our method through experiments on about one thousand sentences. Compared to experiments with other example sampling methods, our method reduced both the overhead for supervision and the overhead for search, without the degeneration of the performance of the system.

An application of synchronized chaotic dynamic arrays
|
Physics Letters, Section A: General, Atomic and Solid State Physics
|
We propose a novel approach for constructing synchronized chaotic arrays and demonstrate its application for encoding messages. When applied to the problem of communicating information signals, in this case, the transmitted signal is a hyper-chaotic. Therefore, this approach provides an efficient encoding of the information and may be useful in private communication applications.

Did Malament prove the non-conventionality of simultaneity in the special theory of relativity?
|
Philosophy of Science
|
David Malament's (1977) well-known result, which is often taken to show the uniqueness of the Poincaré-Einstein convention for defining simultaneity, involves an unwarranted physical assumption: that any simultaneity relation must remain invariant under temporal reflections. Once that assumption is removed, his other criteria for defining simultaneity are also satisfied by membership in the same backward (forward) null cone of the family of such cones with vertices on an inertial path. What is then unique about the Poincaré-Einstein convention is that it is independent of the choice of inertial path in a given inertial frame, confirming a remark in Einstein 1905. Similarly, what is unique about the backward (forward) null cone definition is that it is independent of the state of motion of an observer at a point on the inertial path.

Feedback consolidation and timeout algorithms for point-to-multipoint ABR service
|
IEEE International Conference on Communications
|
The "wait-for-all" feedback consolidation algorithm avoids consolidation noise, but suffers from a slow transient response. Probabilistic Aggregation and Fast Overload Indication techniques have been proposed to preserve the advantages of the "wait-for-all" algorithm and improve its slow transient response. However, these techniques introduce a new "threshold setting" problem. We developed a new consolidation algorithm to provide a fast transient response, a low consolidation noise and flexibility in determining the threshold. In addition, we developed a dynamic timeout mechanism to handle the non-responsive branches where the membership within a multicast session changes due to frequent joining/leaving of members (leaves). © 1999 IEEE.

Kac-Moody construction of Toda type field theories
|
Physics Letters B
|
Using the coadjoint orbit method we derive a geometric WZWN action based on the extended two-loop Kac-Moody algebra. We show that under a hamiltonian reduction procedure, which respects conformal invariance, we obtain a hierarchy of Toda type field theories, which contain as submodels the Toda molecule and periodic Toda lattice theories. We also discuss the classical r-matrix and integrability properties. © 1991.

Exploring wait tolerance in effective batching for video-on-demand scheduling
|
Multimedia Systems
|
In a video-on-demand (VOD) environment, batching requests for the same video to share a common video stream can lead to significant improvement in throughput. Using the wait tolerance characteristic that is commonly observed in viewers behavior, we introduce a new paradigm for scheduling in VOD systems. We propose and analyze two classes of scheduling schemes: the Max_Batch and Min_Idle schemes that provide two alternative ways for using a given stream capacity for effective batching. In making a video selection, the proposed schemes take into consideration the next stream completion time, as well as the viewer wait tolerance. We compared the proposed schemes with the two previously studied schemes: (1) first-come-first-served (FCFS) that schedules the video with the longest waiting request and (2) the maximum queue length (MQL) scheme that selects the video with the maximum number of waiting requests. We show through simulations that the proposed schemes substantially outperform FCFS and MQL in reducing the viewer turn-away probability, while maintaining a small average response time. In terms of system resources, we show that, by exploiting the viewers wait tolerance, the proposed schemes can significantly reduce the server capacity required for achieving a given level of throughput and turn-away probability as compared to the FCFS and MQL. Furthermore, our study shows that an aggressive use of the viewer wait tolerance for batching may not yield the best strategy, and that other factors, such as the resulting response time, fairness, and loss of viewers, should be taken into account.

Compactification structure and conformal compressions of symmetric cones
|
Journal of Lie Theory
|
In this paper we show that the boundary of a symmetric cone Ω in the standard real conformal compactification M of its containing euclidean Jordan algebra V has the structure of a double cone, with the points at infinity forming one of the cones. We further show that Ω̄<sup>M</sup> admits a natural partial order extending that of Ω. Each element of the compression semigroup for Ω is shown to act in an order-preserving way on Ω̄<sup>M</sup> and carries it into an order interval contained in Ω̄<sup>M</sup>.

Null surface geometrodynamics
|
Classical and Quantum Gravity
|
Investigates the dynamical structure of Einstein's theory of gravity using a time parameter whose level surfaces are null hypersurfaces in spacetime. A spacelike foliation of codimension two is used in order to give an invariant kinematic description. Dynamics are analysed via a constrained Hamiltonian formalism. It is found that the Hamiltonian formulation includes both first and second class constraints. The first class constraints are associated with the invariance of the theory with respect to diffeomorphisms of the null hypersurfaces. The second class constraints are direct consequences of the choice of null time parameter.

Achieving diagonal dominance
|
Systems and Control Letters
|
There are many occasions when one would like to see whether a transfer function can be made diagonally dominant. There is the obvious and important case of system design using Rosenbrock's methods, but one also wants to use diagonal dominance (in a different manner) in robustness studies and in several nonlinear system analysis techniques. Commonly, the compensators or similarity transforms used to achieve dominance are designed in an ad hoc way. This paper shows how in the particular case of diagonal compensators or similarity transforms, there is a very easy way, based on Perron-Frobenius theory, of obtaining optimal reduction in the off-diagonal elements. © 1981 North-Holland.

An energy dispersion estimate
|
Physics Letters A
|
Given the density operator ρ{variant}<sub>1</sub> as an initial value of a Hamiltonian motion that evolves in a time interval Δt to ρ{variant}<sub>2</sub>. Then Δt ΔE, ΔE being the energy dispersion (or energy uncertainty) of the motion, can be estimated from below by comparing the length of the Hamiltonian curve with a geodesic joining the initial and the final density operator. The lengths are calculated in the Bures metric. © 1992.

Asset pricing with distorted beliefs: Are equity returns too good to be true?
|
American Economic Review
|
We study a Lucas asset-pricing model that is standard in all respects, except that the representative agent's subjective beliefs about endowment growth are distorted. Using constant relative risk-aversion (CRRA) utility, with a CRRA coefficient below 10; fluctuating beliefs that exhibit, on average, excessive pessimism over expansions; and excessive optimism over contractions (both ending more quickly than the data suggest), our model is able to match the first and second moments of the equity premium and risk-free rate, as well as the persistence and predictability of excess returns found in the data.

A survey of agency models of organizations
|
Journal of Economic Behavior and Organization
|
In recent years Neoclassical economists have begun to turn their attention to issues of firm organization, stimulated in large part by methodological advances in the economics of incentives and incomplete information. The paradigm on which much of this work is based views an organization as an agency relationship. Agency models incorporate two basic features of organizations: incomplete information and goal conflict among members of the organization. This essay characterizes and critiques the existing research on agency models of organizations in order to broaden the set of consumers of such models and to stimulate the production of new research. © 1988.

Stochastic resonance in two coupled bistable systems

We consider the collective response of two coupled bistable oscillators driven by independent noise sources to a periodical force. We have found that there exists an optimal value of the coupling strength for which the signal-to-noise ratio of the collective response has its maximal value. The connection of this effect with the phenomenon of stochastic synchronization is established. © 1995.

The decomposition method applied to systems of partial differential equations and to the reaction-diffusion Brusselator model
|
Applied Mathematics and Computation
|
In this work, systems of linear and nonlinear partial differential equations and the reaction-diffusion Brusselator model are handled by applying the decomposition method. The advantage of this work is twofold. Firstly, the decomposition method reduces the computational work. Secondly, in comparison with existing techniques, the decomposition method is an improvement with regard to its accuracy and rapid convergence. The decomposition method has the advantage of being more concise for analytical and numerical purposes.

Simulated annealing with noisy or imprecise energy measurements
|
Journal of Optimization Theory and Applications
|
The annealing algorithm (Ref. 1) is modified to allow for noisy or imprecise measurements of the energy cost function. This is important when the energy cannot be measured exactly or when it is computationally expensive to do so. Under suitable conditions on the noise/imprecision, it is shown that the modified algorithm exhibits the same convergence in probability to the globally minimum energy states as the annealing algorithm (Ref. 2). Since the annealing algorithm will typically enter and exit the minimum energy states infinitely often with probability one, the minimum energy state visited by the annealing algorithm is usually tracked. The effect of using noisy or imprecise energy measurements on tracking the minimum energy state visited by the modified algorithms is examined. © 1989 Plenum Publishing Corporation.

Simple schemes are presented for lowering the resonant frequency of the rectangular patch antenna without changing its size. In particular, by placing a perturbance below the patch it is shown that as much as 30 percent decrease from the resonant frequency of the unperturbed patch can be achieved. The specific configurations considered include a cavity-backed and an aperture-backed patch and for each case design curves are presented. © 1992 IEEE

Resolutions of the prescribed volume form equation
|
Nonlinear Differential Equations and Applications
|
For a given volume form fdx on a bounded regular domain Ω in ℝ<sup>n</sup>, we are looking for a transformation u of Ω, keeping the boundary fixed and which sends the Lebesgue measure dx into fdx (i.e. we solve det(∇u) = f). For f in various spaces, we propose two different constructions which ensure the existence of u with some gain of regularity. Our methods permit the recovery Dacorogna and Moser's results [4], but also, we prove the existence of such u in Hölder spaces for f in C<sup>0</sup>, or even in L<sup>∞</sup>.

Renormalization group treatment of correlated percolation
|
Physical Review E - Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics
|
A renormalization group procedure is developed for correlated site percolation lattices that can be described by Gaussian statistics. The procedure is a generalization of the procedure for independent site percolation lattices. As an example, a simple renormalization group procedure is generalized from the independent triangular lattice to the correlated triangular lattice. The procedure gives the exact percolation threshold [Formula Presented] for both the independent and the correlated triangular lattice. © 2000 The American Physical Society.

Modal logic over finite structures
|
Journal of Logic, Language and Information
|
We investigate properties of prepositional modal logic over the class of finite structures. In particular, we show that certain known preservation theorems remain true over this class. We prove that a class of finite models is defined by a first-order sentence and closed under bisimulations if and only if it is definable by a modal formula. We also prove that a class of finite models defined by a modal formula is closed under extensions if and only if it is defined by a ◇-modal formula. © 1997 Kluwer Academic Publishers.

Bass numbers of local cohomology modules
|
Transactions of the American Mathematical Society
|
Let A be a regular local ring of positive characteristic. This paper is concerned with the local cohomology modules of A itself, but with respect to an arbitrary ideal of A. The results include that all the Bass numbers of all such local cohomology modules are finite, that each such local cohomology module has finite set of associated prime ideals, and that, whenever such a local cohomology module is Artinian, then it must be injective. (This last result had been proved earlier by Hartshorne and Speiser under the additional assumptions that A is complete and contains its residue field which is perfect.) The paper ends with some low-dimensional evidence related to questions about whether the analogous statements for regular local rings of characteristic 0 are true. © 1993 American Mathematical Society.

On mild and weak solutions of elliptic-parabolic problems
|
Advances in Differential Equations
|
We consider an elliptic-parabolic equation in divergence form b(v)t = div a(v, Dv)+f with Dirichlet boundary conditions and initial condition. Under rather general assumptions, we prove existence of mild solutions satisfying an L1-comparison principle; under some additional conditions, these solutions are shown to be weak solutions. Moreover, under the general assumptions, uniqueness of integral solutions is established; under certain conditions, we show that weak solutions are integral solutions. The notions of mild and integral solutions are derived from nonlinear semigroup theory; by this approach, we extend and make precise former results on existence and uniqueness of weak solutions.

Image subtraction using a space-varying kernel
|
Astronomy and Astrophysics Supplement Series
|
Image subtraction is a method by which one image is matched against another by using a convolution kernel, so that they can be differenced to detect and measure variable objects. It has been demonstrated that constant optimal-kernel solutions can be derived over small sub-areas of dense stellar fields. Here we generalize the theory to the case of space-varying kernels. In particular, it is shown that the CPU cost required for this new extension of the method is almost the same as for fitting a constant kernel solution. It is also shown that constant flux scaling between the images (constant kernel integral) can be imposed in a simple way. The method is demonstrated with a series of Monte-Carlo images. Differential PSF variations and differential rotation between the images are simulated. It is shown that the new method is able to achieve optimal results even in these difficult cases, thereby automatically correcting for these common instrumental problems. It is also demonstrated that the method does not suffer due to problems associated with undersampling of the images. Finally, the method is applied to images taken by the OGLE II collaboration. It is proved that, in comparison to the constant-kernel method, much larger sub-areas of the images can be used for the fit, while still maintaining the same accuracy in the subtracted image. This result is especially important in case of variables located in low density fields, like the Huchra lens. Many other useful applications of the method are possible for major astrophysical problems; Supernova searches and Cepheids surveys in other galaxies, to mention but two. Many other applications will certainly show-up, since variability searches are a major issue in astronomy.

Minimum mean squared estimation of location and scale parameters under misspecification of the model
|
Biometrika
|
SUMMARY: The paper is concerned with estimating location and scale parameters by estimators minimizing a mean squared distance between the empirical distribution function and a conveniently chosen parameterized distribution function. Within the true parametric family the location estimator has the same asymptotic distribution as that of Hodges & Lehmann. If the underlying distribution is not a member of the assumed parametric family, the questions concerning bias, rather than variance, are dominant and most of the paper is concerned with this situation. Numerical results are given for the case of contaminated normal distributions. © 1981 Biometrika Trust.

Duality for multiobjective variational problems
|
Journal of Mathematical Analysis and Applications
|
Wolfe and Mond-Weir type duals for multiobjective variational problems are formulated. Under convexity assumptions on the functions involved weak, and converse duality theorems are proved to relate properly efficient solutions of the primal and dual problems. A close relationship between these variational problems and nonlinear multiobjective programming problems is also indicated. © 1992.

Two-band random matrices
|
Physical Review E - Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics
|
Spectral correlations in unitary invariant, non-Gaussian ensembles of large random matrices possessing an eigenvalue gap are studied within the framework of the orthogonal polynomial technique. Both local and global characteristics of spectra are directly reconstructed from the recurrence equation for orthogonal polynomials associated with a given random matrix ensemble. It is established that an eigenvalue gap does not affect the local eigenvalue correlations that follow the universal sine and the universal multicritical laws in the bulk and soft-edge scaling limits, respectively. By contrast, global smoothed eigenvalue correlations do reflect the presence of a gap, and are shown to satisfy a new universal law exhibiting a sharp dependence on the odd or even dimension of random matrices whose spectra are bounded. In the case of an unbounded spectrum, the corresponding universal “density-density” correlator is conjectured to be generic for chaotic systems with a forbidden gap and broken time reversal symmetry. © 1998 The American Physical Society.

Markov programming by successive approximations with respect to weighted supremum norms
|
Journal of Mathematical Analysis and Applications
|
Markovian decision processes are considered in the situation of discrete time, countable state space, and general decision space. By introducing a Banach space with a weighted supremum norm, conditions are derived, which guarantee convergence of successive approximations to the value function. These conditions are weaker then those required by the usual supnorm approach. Several properties of the successive approximations are derived. © 1977.

Knowledge acquisition for temporal-abstraction mechanisms
|
Knowledge Acquisition
|
We describe three general temporal-abstraction mechanisms needed for managing time-stamped data: point temporal abstraction (a mechanism for abstracting several parameter values into one class); temporal inference (a mechanism for inferring sound logical conclusions over a single interval or two meeting intervals); and temporal interpolation (a mechanism for bridging non-meeting temporal intervals). Making explicit the knowledge required for temporal abstractions supports the acquisition of problem-solving knowledge needed for planning, plan execution, problem identification and plan revision. These mechanisms are implemented in the RÉSUMÉ system, and will be used in the context of our ongoing PROTÉGÉ-II project, whose goal is to generate knowledge-based systems automatically, as well as the appropriate knowledge-acquisition tools, custom-tailored to acquire the specific domain and task knowledge needed by the specific problem-solving method chosen for the task. © 1992.

Approximate factorization of multivariate polynomials and absolute irreducibility testing
|
Japan Journal of Industrial and Applied Mathematics
|
A concept of approximate factorization of multivariate polynomial is introduced and an algorithm for approximate factorization is presented. The algorithm handles polynomials with complex coefficients represented approximately, hence it can be used to test the absolute irreducibility of multivariate polynomials. The algorithm works as follows: given a monic square-free polynomial F(x,y,...,z), it calculates the roots of F(x,y<sub>o</sub>, ..., z<sub>0</sub>) numerically, where y<sub>o</sub>, ... z<sub>0</sub> are suitably chosen numbers, then it constructs power series F1, ..., F<sub>n</sub> such that F(x,y, ..., z) ∈F1 (x,y., ..., z)... F<sub>n</sub>(x,y, ... z) (mod S<sup>e+2</sup>), where n=deg<sub>x</sub> (F), S=(y-y<sub>0</sub>, ..., z-z<sub>0</sub>), and e=max{deg<sub>y</sub>(F), ..., deg<sub>x</sub> (F)}; finally it finds the approximate divisors of F as products of elements of {F<sub>1</sub>, ..., F<sub>n</sub>}. © 1991 JJIAM Publishing Committee.

Improved circuit design for electrostatic self-resonating vibroscopes
|
Review of Scientific Instruments
|
In this paper a new circuit design for automatic electrostatic vibroscopes is presented. Previously, the component which stabilized the self-oscillatory motion of the filament in the feedback loop of electrostatic vibroscopes was a negative temperature coefficient thermistor. In the present system this device is replaced with a programmable analog compander. This modification represents an improvement because response time is faster, the steady-state conditions are more stable, and the overall performance of the vibroscope is less susceptible to errors caused by changes in environmental conditions.

A generalized learning paradigm exploiting the structure of feedforward neural networks
|
IEEE Transactions on Neural Networks
|
In this paper a general class of fast learning algorithms for feedforward neural networks is introduced and described. The approach exploits the separability of each layer into linear and nonlinear blocks and consists of two steps. The first step is the descent of the error functional in the space of the outputs of the linear blocks (descent in the neuron space), which can be performed using any preferred optimization strategy. In the second step, each linear block is optimized separately by using a least squares (LS) criterion. To demonstrate the effectiveness of the new approach, a detailed treatment of a gradient descent in the neuron space is conducted. The main properties of this approach are the higher speed of convergence with respect to methods that employ an ordinary gradient descent in the weight space backpropagation (BP), better numerical conditioning, and lower computational cost compared to techniques based on the Hessian matrix. The numerical stability is assured by the use of robust LS linear system solvers, operating directly on the input data of each layer. Experimental results obtained in three problems are described, which confirm the effectiveness of the new method. © 1996 IEEE.

Optimal minimal-order observers for discrete-time systems-A unified theory
|
Automatica
|
Luenberger's minimal-order observer is considered as an alternate to the Kalman filter for obtaining state estimates in linear discrete-time stochastic systems. The general solution to the problem of constructing the optimal minimal-order observer is presented for systems having white noise disturbances. In the special case of no measurement noise the observer estimation errors are shown to be identical with those of the corresponding Kalman filter. Estimation errors comparable with the Kalman filter are obtained when measurement noise is not excessive. The observer solution is extended to systems for which the noise disturbances are time-wise correlated processes of the Markov type. In considering correlated noise inputs, the system state equations are not augmented as is done in the usual Kalman filtering theory. The observer solution, modified appropriately to account for the time-wise correlation of the noise inputs, yields minimum mean-square estimates of the state vector. Application of the theory to the design of a radar tracking system shows that the performance obtained using a minimal-order observer may be comparable to that achieved with a Kalman filter.

Reaction-diffusion equations for interacting particle systems
|
Journal of Statistical Physics
|
We study interacting spin (particle) systems on a lattice under the combined influence of spin flip (Glauber) and simple exchange (Kawasaki) dynamics. We prove that when the particle-conserving exchanges (stirrings) occur on a fast time scale of order e{open}<sup>-2</sup> the macroscopic density, defined on spatial scale e{open}<sup>-1</sup>, evolves according to an autonomous nonlinear diffusion-reaction equation. Microscopic fluctuations about the deterministic macroscopic evolution are found explicitly. They grow, with time, to become infinite when the deterministic solution is unstable. © 1986 Plenum Publishing Corporation.

MIL primitives for querying a fragmented world
|
VLDB Journal
|
In query-intensive database application areas, like decision support and data mining systems that use vertical fragmentation have a significant performance advantage. In order to support relational or object oriented applications on top of such a fragmented data model, a flexible yet powerful intermediate language is needed. This problem has been successfully tackled in Monet, a modern extensible database kernel developed by our group. We focus on the design choices made in the Monet interpreter language (MIL), its algebraic query language, and outline how its concept of tactical optimization enhances and simplifies the optimization of complex queries. Finally, we summarize the experience gained in Monet by creating a highly efficient implementation of MIL.

Dressed solitonic excitations for the AKLT Hamiltonian
|
Journal of Physics: Condensed Matter
|
In contrast to the ground state of the Affleck-Kennedy-Lieb-Tasaki (AKLT) isotropic spin-1 Hamiltonian its elementary excitations are not known exactly in general. Based on a simple variational ansatz we construct approximate excitations in the form of dressed hidden domain walls. This allows us to give an improved upper bound for the gap of the AKLT Hamiltonian which is only 1% larger than the best currently available numerical result. We compare the oneand two-soliton dispersion curves with low-lying excitations for a chain of 16 sites as given by Fath and Solyom and find excellent agreement. Spin and string correlations are calculated and found to agree in leading order with the corresponding correlations for the bare kinks. Finally the weight of the string-ordered part of the lowest excited state is calculated and compared with the exact numerical result.

Gaussian core model in two dimensions. I. Melting transition
|
The Journal of Chemical Physics
|
The method of molecular dynamics computer simulation has been used to examine the solid-fluid transition for the Gaussian core model in two dimensions. The system contained 780 particles subject to periodic boundary conditions, and confined to a single reduced density ρ* = 3 <sup>-1/2</sup>. The virial pressure, mean potential energy, and pair correlation functions all indicate that the melting process is first order. However, the system is anomalous in that thermal expansivities of the solid and (low temperature) fluid phases are negative, and the density change on melting at constant pressure is positive. © 1981 American Institute of Physics.

Semiparametric estimation of the binary choice model for contingent valuation
|
Land Economics
|
This paper is concerned with the estimation of the binary choice model without imposing any parametric structure on the distribution of the stochastic term. We adapt the distribution-free maximum likelihood method developed by Cosslett (1983) for deriving the contingent value function with respect to observable exogenous variables. We present Monte Carlo comparisons with the probit estimates and discuss the asymptotic consistency and relative efficiency of the approach. Data from a forest environment valuation survey are used for empirical estimations.

Environmental controls, scarcity rents, and pre-existing distortions
|
Journal of Public Economics
|
One might suppose that an emissions tax has an advantage over command and control (CAC) regulations since it raises revenue that can be used to cut other distorting taxes. In this paper, we show that the focus on revenue raising is misplaced. In a simple analytical general equilibrium model, we show that the same welfare effects of environmental protection can be achieved, by taxes that raise revenue, certain command and control regulations that raise no revenue, and even subsidies that cost revenue. Instead, the pre-existing labor tax distortion is exacerbated by policies that generate privately-retained scarcity rents. © Elsevier Science B.V.

Weak lensing from strong clustering
|
Monthly Notices of the Royal Astronomical Society
|
We investigate the effect of weak gravitational lensing in the limit of small angular scales where projected galaxy clustering is strongly non-linear. This is the regime likely to be probed by future weak lensing surveys. We use well-motivated hierarchical scaling arguments and the plane-parallel approximation to study multi-point statistical properties of the convergence field. These statistics can be used to compute the vertex amplitudes in tree models of hierarchical clustering; these can be compared with similar measurements from galaxy surveys, leading to a powerful probe of galaxy bias.

Investigating optimal coordinates for describing vibrational motion
|
Theoretica Chimica Acta
|
Results of independent mode models of molecular vibrations of SO<sub>2</sub> and H<sub>2</sub>O are compared to converged eigenvalues and eigenfunctions. Energies of self-consistent-field and adiabatic wave functions are calculated and compared to the eigenvalues; Brueckner functions and natural modals are compared to the eigenfunctions. These comparisons are made for a class of normal coordinates of varying curvature. Of the coordinates we considered, an independent mode model based on rectilinear normal coordinates provides the best description of the energetics yet provides the poorest description of the eigenfunctions. The ramifications of this finding are discussed for both independent mode models and perturbative descriptions of molecular vibrations. © 1995 Springer-Verlag.

User participation in system development revisited
|
Information and Management
|
There is an extensive literature on user participation in system development. Individual papers discuss separate components of the participation issue. Papers study individual factors associated with participation, investigate the process of participation and discuss the link between participation and system success. In spite of the many studies in this area, findings are not consistent or cumulative. One reason for this may be that participation is a nebulous term that is difficult to define clearly: it is a concept with many dimensions. This paper highlights a number of attributes of participation, presents a framework which is used to describe and synthesise existing research findings, and includes an analysis of empirical literature in an attempt to explain inconsistency in findings. © 1995.

Fermion mass prediction from infra-red fixed points
|
Physics Letters B
|
We argue that in a wide class of theories the fermion and soft supersymmetry breaking mass structure is largely determined by the infra-red fixed point structure of the theory lying beyond the standard model. We show how knowlege of the symmetries and multiplet content of this theory is sufficient to determine the infra-red structure, illustrating the idea for the case of a simple abelian family symetry. The resulting structure determines the fermion masses and mixing angles in terms of a restricted number of parameters. © 1995.

Analytical and numerical studies of the Bonhoeffer Van der Pol system
|
Journal of the Australian Mathematical Society Series B-Applied Mathematics
|
The Bonhoeffer Van der Pol system is a planar autonomous nonlinear system of differential equations which has been invoked as a qualitative model of physiological states in a nerve membrane. It contains three independent parameters and previous work has only studied a small portion of the parameter space, that part which is thought to be of physiological relevance. Here we give a complete study of the full parameter space, using both theoretical results and numerical solutions. © Australian Mathematical Society, 1997.

A new artificial neural network tracking technique for particle image velocimetry
|
Experiments in Fluids
|
The analysis of Particle Image Velocimetry (PIV) data requires effective algorithms to track efficiently the particles suspended in the fluid flow. The artificial neural network algorithm method described here presents a new approach to solve this problem. Contrary to the classic cross correlation method, this new method does not require a large number of particles per frame, it can handle flows with large velocity gradients, and is suited for tracking images with multiple exposures as well as tracking through consecutive images. The algorithm was tested on synthetic and available experimental data to provide a thorough performance analysis.

Nonlinear biplots
|
Biometrika
|
The classical biplot (Gabriel, 1971) of a multivariate sample X of n units by p variables is generalized for any Euclidean imbeddable metric d<sub>ij</sub>. Sample-units are represented in the usual way by points in an ordination, most conveniently using principal coordinates. Variables are represented by a set of p concurrent nonlinear trajectories whose lengths and dispositions relative to the sample points aid interpretation. When d<sub>ij</sub><sup>2</sup> is defined to have independent contributions from each variable, the centroid of any p points, one on each trajectory, may be used to interpolate and interpret sample points in the ordination. The basic idea may be exploited further for use with any form of metric or nonmetric scaling and for structured multivariate samples. © 1988 Biometrika Trust.

Unified Model of Attention and Problem Solving
|
Psychological Review
|
A model of information processing has been developed that combines concepts from the study of attention and the study of problem solving. The model is based on the idea that certain concepts drawn from recent theories of attention can be used to construct a psychologically motivated interpreter for production system simulations of problem solving. Within the model, automatic processing is explained in terms of the spread of activation between related productions and is independent of working memory. Controlled processing consists of the execution of a sequence of productions that manipulate the contents of working memory. The model has been realized as a computer program and used to simulate a variety of phenomena from the attention and performance literature. The relevant simulations are described. The model inherits the simulation capabilities of production-oriented simulations of problem solving, because it is an interpreter of productions. The model is compared to several other current models of attention and problem solving. © 1986 American Psychological Association.

Effective bifurcation analysis: A time-stepper-based approach
|
Nonlinearity
|
We introduce a numerical approach to perform the effective (coarse-scale) bifurcation analysis of solutions of dissipative evolution equations with spatially varying coefficients. The advantage of this approach is that the 'coarse model' (the averaged, effective equation) need not be explicitly constructed. The method only uses a time-integrator code for the detailed problem and judicious choices of initial data and integration times; the bifurcation computations are based on the so-called recursive projection method (Shroff and Keller 1993 SIAM J. Numer. Anal. 30 1099-120).

Shortest path problems with node failures
|
Networks
|
Consider the problem of finding the shortest paths from a node source s to a node sink t in a complete network. On any given instance of the problem, only a subset of the intermediate nodes can be used to go from s to t, the subset being chosen according to a given probability law. We wish to find an a priori path from s to t such that, on any given instance of the problem, the sequence of nodes defining the path is preserved but only the permissible nodes are traversed, the others being skipped. The problem of finding an a priori path of minimum expected length is defined as the Probabilistic Shortest Path Problem (PSPP). Note that if the network is not originally complete, the PSPP methodology can still be used if we first add each missing edge, together with a deterministic length (being defined by an alternative path using nodes that have no probability of failure). In this paper, after discussing potential applications of the PSPP, we study the complexity of this class of problems. We first show that the problem is, in general, NP‐hard and then we develop polynomial time procedures for special cases of it. We also consider the complexity of a related problem: the Probabilistic Minimum Spanning Tree Problem (PMSTP). Finally, we provide a discussion of the implications of the results.

Non-Abelian symmetries of stochastic processes: Derivation of correlation functions for random-vertex models and disordered-interacting-particle systems
|
Physical Review E
|
We consider systems of particles hopping stochastically on d-dimensional lattices with space-dependent probabilities. We map the master equation onto an evolution equation in a Fock space where the dynamics are given by a quantum Hamiltonian (continuous time) or a transfer matrix (discrete time). Using non-Abelian symmetries of these operators we derive duality relations, expressing the time evolution of a given initial configuration in terms of correlation functions of simpler dual processes. Particularly simple results are obtained for the time evolution of the density profile. As a special case we show that for any SU(2) symmetric system the two-point and three-point density correlation functions in the N-particle steady state can be computed from the probability distribution of a single particle moving in the same environment. We apply our results to various models, among them partial exclusion, a simple diffusion-reaction system, and the two-dimensional six-vertex model with space-dependent vertex weights. For a random distribution of the vertex weights one obtains a version of the random-barrier model describing diffusion of particles in disordered media. We derive exact expressions for the averaged two-point density correlation functions in the presence of weak, correlated disorder. © 1994 The American Physical Society.

Nonequilibrium behavior of charged point defects during phosphorus diffusion in silicon
|
Journal of Applied Physics
|
A new nonequilibrium kinetic model for phosphorus diffusion in silicon is presented. Concentrations of charged defects and defect-impurity pairs are determined explicitly by solving a system of quasilinear evolution equations, each of a drift-diffusion-reaction form with constant diffusivities. This formulation subsumes a hierarchy of models from the literature. Calculated profiles for a 10-min predeposition show both a tail and a well-defined kink plateau. The latter results directly from the kinetic model under the assumption of a strong bimolecular recombination.

Dynamic work function shift in cold cathode emitters using current carrying thin films
|
Journal of Applied Physics
|
We analyze a new cold cathode emitter which consists of a thin wide band gap semiconductor material sandwiched between a metallic material, and a low work function semimetallic thin film. We show that under forward bias operation the electrons captured in the low work function material are responsible for an effective reduction of the semimetallic film work function, together with a substantial increase of the cathode emitted current. The dynamic work function shift is shown to increase with the amount of injected current. Potential material candidates are suggested to achieve low-voltage (<20 V), room-temperature cold cathode operation with emission currents approaching several hundred A/cm<sup>2</sup> and large efficiencies. © 1996 American Institute of Physics.

Hyperchaos in the generalized Rössler system
|
Physical Review E - Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics
|
Introduced as a model for hyperchaos, the generalized Rössler system of dimension [Formula Presented] is obtained by linearly coupling [Formula Presented] additional degrees of freedom to the original Rössler equation. Under variation of a single control parameter, it is able to exhibit the chaotic hierarchy ranging from fixed points via limit cycles and tori to chaotic and, finally, hyperchaotic attractors. Through the help of a mode transformation, we reveal a structural symmetry of the generalized Rössler system. The latter will allow us to interpret the number, shape, and location in phase space of the observed coexisting attractors within a common scheme for arbitrary odd dimension [Formula Presented] The appearance of hyperchaos is explained in terms of interacting coexisting attractors. In a second part, we investigate the Lyapunov spectra and related properties of the generalized Rössler system as a function of the dimension [Formula Presented] We find scaling properties which are not similar to those found in homogeneous, spatially extended systems, indicating that the high-dimensional chaotic dynamics of the generalized Rössler system fundamentally differs from spatiotemporal chaos. If the time scale is chosen properly, though, a universal scaling function of the Lyapunov exponents is found, which is related to the real part of the eigenvalues of an unstable fixed point. © 1997 The American Physical Society.

Bounded contraction and gentzen-style formulation of lukasiewicz logics
|
Studia Logica
|
In this paper, we consider multiplicative-additive fragments of affine propositional classical linear logic extended with n-contraction. To be specific, n-contraction (n > 2) is a version of the contraction rule where (n+ 1) occurrences of a formula may be contracted to n occurrences. We show that expansions of the linear models for (n + 1)valued Lukasiewicz logic are models for the multiplicative-additive classical linear logic, its affine version and their extensions with n-contraction. We prove the finite axiomatizability for the classes of finite models, as well as for the class of infinite linear models based on the set of rational numbers in the interval [0,1J. The axiomatizations obtained in a Gentzen-style formulation are equivalent to finite and infinite-valued Lukasiewicz logics. © 1996 Kluwer Academic Publishers.

Taming disk/spindle vibrations through aerodynamic bearings and acoustically tuned-mass dampers
|
IEEE Transactions on Magnetics
|
This paper studies the feasibility of suppressing the vibration of a spinning disk/spindle system by creating an aerodynamic bearing between the spinning disks and adjacent stationary flat surfaces. An automated impact hammer was first developed and instrumented to obtain repeatable and consistent frequency response functions (FRF). Through this device, frequency response functions of a 5-platter disk/spindle system were measured in the air and in the vacuum up to 7,200 rpm with and without an air bearing, which consists of a flat surface 0.635 mm (25 mils) away from the top spinning disk. Compared with the experimental results in vacuum, the presence of the air (without the air bearing) causes the resonance frequencies of the disk/spindle system to split resulting in smaller resonance amplitudes. Nevertheless, the splitting does not increase the modal dampings of the disk/spindle system. When the air bearing is present, the air bearing does not further reduce the resonance amplitudes, but it does increase the modal dampings by 100-200%. Moreover, the presence of the air bearing lowers the resonance frequencies by 3%, because the air in the bearing behaves like incompressible fluid adding considerable inertia to the disk/spindle system. Also, the increase in damping and shift in natural frequencies are independent of the rotational speed. Finally, combination of the air bearing and a tuned-mass damper can significantly reduce the resonance amplitudes by 50-75%. © 1999 IEEE.

Very high radix square root with prescaling and rounding and a combined division/square root unit
|
IEEE Transactions on Computers
|
An algorithm for square root with prescaling and selection by rounding is developed and combined with a similar scheme for division. Since division is usually more frequent than square root, the main concern of the combined implementation is to maintain the low execution time of division, while accepting a somewhat larger execution time for square root. The algorithm is presented in detail, including the mathematical development of bounds for the first square-root digit and for the scaling factor. The proposed implementation is described, evaluated and compared with other combined div/sqrt units. The comparisons show that the proposed scheme potentially produces a significant speed-up for division, whereas, for square root, the speed-up is small. © 1999 IEEE.

Earnings functions. Testing for the demand side
|
Economics Letters
|
To analyze labor market phenomena, one may simultaneously grade workers (by education) and jobs (by level of difficulty and complexity). Human capital theory predicts earnings based on only worker quality. Thurow's version of a segmented labor market theory predicts that only the job level is relevant, and the assignment theory predicts that both variables are relevant. Using three different data sets for The Netherlands, testing demonstrates convincingly the superiority of the assignment theory. © 1985.

Fractional dynamics, irreversibility and ergodicity breaking
|
Chaos, Solitons and Fractals
|
Time flow in dynamical systems is analysed within the framework of ergodic theory from the perspective of a recent classification theory of phase transitions. Induced automorphisms are studied on subsets of measure zero. The induced transformations are found to be stable convolution semigroups rather than translation groups. This implies non-uniform flow of time, time irreversibility and ergodicity breaking. The induced semigroups are generated by fractional time derivatives. Stationary states with respect to fractional dynamics are dissipative in the sense that the measure of regions in phase space may decay algebraically with time although the measure is time transformation invariant. © 1995.

The look ahead dispatching procedure
|
International Journal of Production Research
|
The look ahead dispatching procedure is an approximation method for solving the minimum makespan problem for job shops with routing flexibility. It is a dispatching procedure in the sense that each run of the procedure results in a specification of only one next operation for every machine in the system. The selection of these operations is based on a limited search in the space of possible states the system can reach within approximately twice the average cycle time. This search uses a newly developed representation of the state space, and a newly developed evaluation function. The results are considerably better than those obtained with ordinary priority dispatching rules. In the last section of the paper we discuss how this procedure can be used for the real time control of Flexible Manufacturing Systems (FMS). © 1990 Taylor & Francis Group, LLC.

Bezoutians
|
Linear Algebra and Its Applications
|
We survey the theory of Bezoutians with a special emphasis on its relation to system theoretic problems. Some instances are the connections with realization theory, in particular signature symmetric realizations, the Cauchy index, stability, and the characterization of output feedback invariants. We describe canonical forms and invariants for the action of static output feedback on scalar linear systems of McMillan degree n. Previous results on this subject are obtained in a new and unified way, by making use of only a few elementary properties of Bezout matrices. As new results we obtain a minimal complete set of 2n-2 independent invariants, an explicit example of a continuous canonical form for the case of odd McMillan degree, and finally a canonical form which induces a cell decomposition of the quotient space for output feedback. © 1989.

Markov Localization for Mobile Robots in Dynamic Environments
|
Journal of Artificial Intelligence Research
|
Localization, that is the estimation of a robot's location from sensor data, is a fundamental problem in mobile robotics. This papers presents a version of Markov localization which provides accurate position estimates and which is tailored towards dynamic environments. The key idea of Markov localization is to maintain a probability density over the space of all locations of a robot in its environment. Our approach represents this space metrically, using a fine-grained grid to approximate densities. It is able to globally localize the robot from scratch and to recover from localization failures. It is robust to approximate models of the environment (such as occupancy grid maps) and noisy sensors (such as ultrasound sensors). Our approach also includes a filtering technique which allows a mobile robot to reliably estimate its position even in densely populated environments in which crowds of people block the robot's sensors for extended periods of time. The method described here has been implemented and tested in several real-world applications of mobile robots, including the deployments of two mobile robots as interactive museum tour-guides.

Bayesian analysis of seasonal unit roots and seasonal mean shifts
|
Journal of Econometrics
|
In this paper we propose a Bayesian analysis of seasonal unit roots in quarterly observed time series. Seasonal unit root processes are useful to describe economic series with changing seasonal fluctuations. A natural alternative model for similar purposes contains deterministic seasonal mean shifts instead of seasonal stochastic trends. This leads to analysing seasonal unit roots in the presence of mean shifts using Bayesian techniques. Our method is illustrated using several simulated and empirical data.

Efficient design with interdependent valuations
|
Econometrica
|
We study efficient, Bayes-Nash incentive compatible mechanisms in a social choice setting that allows for informational and allocative externalities. We show that such mechanisms exist only if a congruence condition relating private and social rates of information substitution is satisfied. If signals are multi-dimensional, the congruence condition is determined by an integrability constraint, and it can hold only in nongeneric cases where values are private or a certain symmetry assumption holds. If signals are one-dimensional, the congruence condition reduces to a monotonicity constraint and it can be generically satisfied. We apply the results to the study of multi-object auctions, and we discuss why such auctions cannot be reduced to one-dimensional models without loss of generality.

The HUMP-shaped behavior of macroeconomic fluctuations
|
Empirical Economics
|
We analyze the nature of persistence in macroeconomic fluctuations. The current view is that shocks to macroeconomic variables (in particular real GNP) have effects that endure over an indefinite horizon. This conclusion is drawn from the presence of a unit root in the univariate time series representation. Following Perron (1989), we challenge this assessment arguing that most macroeconomic variables are better construed as stationary fluctuations around a breaking trend function. The trend function is linear in time except for a sudden change in its intercept in 1929 (The Great Crash) and a change in slope after 1973 (following the oil price shock). Using a measure of persistence suggested by Cochrane (1988) we find that shocks have small permanent effects, if any. To analyze the effects of shocks at finite horizon, we select a member of the ARMA(p, q) class applied to the appropriately detrended series. For the majority of the variables analyzed the implied weights of the moving-average representation have the once familiar humped shape. © 1993 Physica-Verlag.

Representations of function algebras, abstract operator spaces, and Banach space geometry
|
Journal of Functional Analysis
|
Let G be the closed unit ball of some norm on C<sup>n</sup>, and let A(G) be the closure of the polynomials in the sup norm. We prove that if n ≥ 5 then there is a contractive representation of A(G) as operators on a Hilbert space which is not completely contractive. Our technique involves introducing a numerical invariant α(X) for a normed space X which measures the difference between the minimal operator space structure which can be assigned to X, MIN(X), and the maximal structure, MAX(X). We estimate α(X) using Banach space techniques. We also prove that if X is any infinite dimensional subspace of the space of continuous functions on a compact Hausdorff space, then there exists a bounded linear map on X which is not completely bounded. © 1992.

Photoionization of naphthalene clusters via excimer formation
|
Chemical Physics Letters
|
The excimer formation that occurs subsequent to excitation of the naphthalene trimer and tetramer has been probed by mass-selective pump-probe photoionization spectroscopy. The excimer is identified as a strongly bound dimer core, surrounded by ground-state naphthalene molecules. We show direct evidence that these clusters ionize with high efficiency via excimer formation. The ionization enhancement is explained by large Franck-Condon factors for the ionizing transition from the excimer state. © 1993.

High-speed CCD movie camera with random pixel selection, for neurobiology research
|
Proceedings of SPIE - The International Society for Optical Engineering
|
Wehave designed and built a CCD camera capable of producing movies at over 1000 frames per second. For maximum frame rate, we have incorporated the ability to digitize only the pixels of interest, user-selectable from a custom LabView interface. With a resolution of 64x64 pixels, the system is intended to bridge the gap between fast, small photodiode arrays, and slow, high-resolution scientific CCD cameras. The system was designed for imaging neurons labeled with voltage-sensitive dyes, to allow the simultaneous recording of neural activity in a large number of neurons, or to probe the membrane voltage at many different points of a single neuron. © 1997 SPIE.

Simplified closed-form trap-assisted tunneling model applied to nitrided oxide dielectric capacitors
|
Journal of Applied Physics
|
Conduction has been studied in ultrathin nitrided oxide, re-oxidized nitrided oxide, and nitrogen-annealed nitrided oxide film capacitors in which the nitridation step was performed by a low-partial-pressure nitridation technique. Results indicate that, as well as some degree of barrier lowering due to the build-up of nitrogen at the injecting interface, a trap-assisted mechanism could be responsible for the enhanced conduction exhibited by the nitrided oxide devices. A simplified closed-form trap-assisted tunneling model is employed that produces a fit to the data with a trap depth of 2.1 eV. The difference between this trap model and a model requiring numerical integration was negligibly small (∼2%).

Nonparametric estimation of triangular simultaneous equations models
|
Econometrica
|
This paper presents a simple two-step nonparametric estimator for a triangular simultaneous equation model. Our approach employs series approximations that exploit the additive structure of the model. The first step comprises the nonparametric estimation of the reduced form and the corresponding residuals. The second step is the estimation of the primary equation via nonparametric regression with the reduced form residuals included as a regressor. We derive consistency and asymptotic normality results for our estimator, including optimal convergence rates. Finally we present an empirical example, based on the relationship between the hourly wage rate and annual hours worked, which illustrates the utility of our approach.

The power of two choices in randomized load balancing
|
IEEE Transactions on Parallel and Distributed Systems
|
We consider the following natural model: Customers arrive as a Poisson stream of rate λn, λ < 1, at a collection of n servers. Each customer chooses some constant d servers independently and uniformly at random from the n servers and waits for service at the one with the fewest customers. Customers are served according to the first-in first-out (FIFO) protocol and the service time for a customer is exponentially distributed with mean 1. We call this problem the supermarket model. We wish to know how the system behaves and in particular we are interested in the effect that the parameter d has on expected time a customer spends in the system in equilibrium. Our approach uses a limiting, deterministic model representing the behavior as n → ∞ to approximate the behavior of finite systems. The analysis of the deterministic model is interesting in its own right. Along with a theoretical justification of this approach, we provide simulations that demonstrate that the method accurately predicts system behavior, even for relatively small systems. Our analysis provides surprising implications: Having d = 2 choices leads to exponential improvements in the expected time a customer spends in the system over d = 1, whereas having d = 3 choices is only a constant factor better than d = 2. We discuss the possible implications for system design.

Hybrid Monte Carlo and quantum chromodynamics
|
Nuclear Physics, Section B
|
In this paper we study the properties of the hybrid Monte Carlo algorithm applied to lattice quantum chromodynamics including the dynamical effects of fermions. We find that this "exact" method performs very well on 4<sup>4</sup> lattices, and shows considerable promise for being a practicable means with which to undertake realistic Monte Carlo computations of fermionic systems. © 1989.

Stochastic common learning
|
Games and Economic Behavior
|
We present a general model in which agents learn by observing a stochastic process. We show that agents not only learn in such a model but also learn commonly. By this we mean that in the long run agents will form common beliefs concerning important facts and in particular they will commonly believe that their views regarding the future are similar.

Provably good partitioning and load balancing algorithms for parallel adaptive N-body simulation
|
SIAM Journal of Scientific Computing
|
We present an efficient and provably good partitioning and load balancing algorithm for parallel adaptive N-body simulation. The main ingredient of our method is a novel geometric characterization of a class of communication graphs that can be used to support hierarchical N-body methods such as the fast multipole method (FMM) and the Barnes-Hut method (BH). We show that communication graphs of these methods have a good partition that can be found efficiently sequentially and in parallel. In particular, we show that an N-body communication graph (either for BH or for FMM) can be partitioned into two subgraphs with equal computation load by removing only O(√n log n) and O(n<sup>2/3</sup>(log n)<sup>1/3</sup>) number of nodes, respectively, for two and three dimensions. These bounds on node-partition imply bounds on edge-partition of O(√n(log n)<sup>3/2</sup>) and O(n<sup>2/3</sup>(log n)<sup>4/3</sup>), respectively, for two and three dimensions. To the best of our knowledge, this is the first theoretical result on the quality of partitioning N-body communication graphs for nonuniformly distributed particles. Our results imply that parallel adaptive N-body simulation can be made as scalable as computation on regular grids and as efficient as parallel N-body simulation on uniformly distributed particles.

Kinetic Ising model for polymer dynamics. II. Generalized transition rates and the Williams-Watts nonexponential function
|
The Journal of Chemical Physics
|
We continue our study [J. Chem. Phys. 79, 1955 (1983)] of the one-dimensional kinetic lsing model to investigate cooperative dynamics in amorphous polymers. In this paper we consider the most general single spin-flip model. The spin-spin correlation function is calculated approximately using continued fractions. We find that the Williams-Watts empirical function φ(t)=exp[-(t/τ)<sup>β</sup>] with 1/2≤β≤1 provides a good fit to this correlation function. The results are interpreted in terms of the dynamics of domain wall defects in which the two fundamental processes are defect migration and defect creation and annihilation. This suggests possible microscopic mechanisms for relaxation in solid amorphous polymers. © 1985 American Institute of Physics.
