Consistent Correspondence between Arbitrary Manifold Surfaces

We propose a novel framework for consistent correspondence between arbitrary manifold meshes. Different from most existing methods, our approach directly maps the connectivity of the source mesh onto the target mesh without needing to segment input meshes, thus effectively avoids dealing with unstable extreme conditions (e.g. complex boundaries or high genus). In this paper, firstly, a novel mean-value Laplacian fitting scheme is proposed, which aims at computing a shape-preserving (conformal) correspondence directly in 3D-to-3D space, efficiently avoiding local optimum caused by the nearest-point search, and achieving good results even with only a few marker points. Secondly, we introduce a vertex relocation and projection approach, which refines the initial fitting result in the way of local conformity. Each vertex of the initial result is gradually projected onto the target model's surface to ensure a complete surface match. Furthermore, we provide a fast and effective approach to automatically detect critic points in the context of consistent correspondence. By fitting these critic points that capture the important features of the target mesh, the output compatible mesh matches the target mesh's profiles quite well. Compared with previous approaches, our scheme is robust, fast, and convenient, thus suitable for common applications.
Quantum gravitational fluctuations and the semi-classical limit

An attempt is made to go beyond the standard semi-classical approximation for gravity in the Born-Oppenheimer decomposition of the wave-function in minisuperspace. New terms are included which correspond to quantum gravitational fluctuations on the background metric. They induce a back-reaction on the semi-classical background and can lead to the avoidance of the singularities the classical theory predicts in cosmology and in the gravitational collapse of compact objects.
Genetically Diverse Filoviruses in Rousettus and Eonycteris spp. Bats, China, 2009 and 2015

Genetically divergent filoviruses detected in Rousettus and Eonycteris spp. bats in China exhibited 61%–99% nt identity with reported filoviruses, based on partial replicase sequences, and they demonstrated lung tropism. Co-infection with 4 different filoviruses was found in 1 bat. These results demonstrate that fruit bats are key reservoirs of filoviruses.
Natural Resource Management and Poverty Reduction

This paper considers the relationship between natural resource management and poverty by analysing a specific example: an inland fishery in Bangladesh. The analysis involves substantial extensions to standard models and allows the simulation of market distortions and alternative management policies, using data from the fishery. The simulations show that fish migration is the most important distortion. They also show that both wage reductions and bans on capital-intensive gears can increase employment, and so reduce poverty, without endangering the sustainability of the resource. The techniques used here can be applied to other fisheries and non-fish natural resources.
Linear higher-order pre-unification

We develop an efficient representation and a pre-unification algorithm in the style of Huet (1975) for the linear /spl lambda/-calculus /spl lambda//sup /spl rarr//spl rArr/0&T/ which includes intuitionistic functions (/spl rarr/), linear functions (/spl rArr/), additive pairing (&), and additive unit (T). Applications lie in proof scorch, logic programming, and logical frameworks based on linear type theories. We also show that, surprisingly, a similar pre-unification algorithm does not exist for certain sublanguages.
Self-fulfilling bank panics : how to avoid them ? an experimental study

The purpose of this paper is to verify experimentally the possibility and the degree of persistence of a self-fulfilling bank panic. Furthermore, we test various means to prevent or to curb it: the suspension of deposit convertibility, the "narrow banking" solution. We confirm the possibility of pure-panic bank runs as formalized by Diamond and Dybvig (1983). However, this situation remains rare. Partial and self-fulfilling bank runs represent a more general situation. That reinforces the idea of strong coordination failures as it was observed in the previous experimental literature. Panics are proved to be persistent phenomena which are difficult to prevent. However, it seems to be possible to curb them using a learning effect entailed by a temporary but enough long suspension of the deposit convertibility or using a narrow banking solution which enables banks to be more liquid.
Use of comorbidity scores for control of confounding in studies using administrative databases.

BACKGROUND Comorbidity scores are increasingly used to reduce potential confounding in epidemiological research. Our objective was to compare metrical and practical properties of published comorbidity scores for use in epidemiological research with administrative databases. METHODS The literature was searched for studies of the validity of comorbidity scores as predictors of mortality and health service use, as measured by change in the area under the receiver operating characteristic (ROC) curve for dichotomous outcomes, and change in R(2) for continuous outcomes. RESULTS Six scores were identified, including four versions of the Charlson Index (CI) which use either the three-digit International Classification of Diseases, Ninth Revision (ICD-9) or the full ICD-9-CM (clinical modification) code, and two versions of the Chronic Disease Score (CDS) which used outpatient pharmacy records. Depending on the population and exposure under study, predictive validities varied between c = 0.64 and c = 0.77 for in-hospital or 30-day mortality. This is only a slight improvement over age adjustment. In one study the simple measure 'number of diagnoses' outperformed the CI (c = 0.73 versus c = 0.65). Proprietary scores like Ambulatory Diagnosis Groups and Patient Management Categories do not necessarily perform better in predicting mortality. Comorbidity indices are susceptible to a variety of coding errors. CONCLUSIONS Comorbidity scores, particularly the CDS or D'Hoore's CI based on three-digit ICD-9 codes, may be useful in exploratory data analysis. However, residual confounding by comorbidity is inevitable, given how these scores are derived. How much residual confounding usually remains is something that future studies of comorbidity scores should examine. In any given study, better control for confounding can be achieved by deriving study-specific weights, to aggregate comorbidities into groups with similar relative risks of the outcomes of interest.
Technology and Production Fragmentation: Domestic versus Foreign Sourcing

This paper provides direct empirical evidence on the relationship between technology and firms' global sourcing strategies. Using new data on U.S. firms' decisions to contract for manufacturing services from domestic or foreign suppliers, I show that a firm's adoption of communication technology between 2002 to 2007 is associated with a 3.1 point increase in its probability of fragmentation. The effect of firm technology also differs significantly across industries; in 2007, it is 20 percent higher, relative to the mean, in industries with production specifications that are easier to codify in an electronic format. These patterns suggest that technology lowers coordination costs, though its effect is disproportionately higher for domestic rather than foreign sourcing. The larger impact on domestic fragmentation highlights its importance as an alternative to offshoring, and can be explained by complementarities between technology and worker skill. High technology firms and industries are more likely to source from high human capital countries, and the differential impact of technology across industries is strongly increasing in country human capital.
Free Light Chains and Intrathecal B Cells Activity in Multiple Sclerosis: A Prospective Study and Meta-Analysis

Background. The presence of CSF oligoclonal bands (OBs) is an independent prognostic factor for multiple sclerosis (MS), but the difficulties in the standardization of the test and the interlaboratory variation in reporting have contributed to its limited use in the diagnosis of the disease. Standard nephelometric assays to measure free light chains (FLC) levels have been recently developed and the test may improve the detection of intrathecal B cells activity. Methods. The presence of OBs, kappa and lambda FLC levels, and standard indices of intrathecal inflammation were assessed in 100 consecutive patients, including patients with MS, clinically isolated syndromes (CIS), other inflammatory diseases of the CNS, and other noninflammatory diseases. Results. Both KFLC and LFLC correlated strongly with the presence of OCBs and with all common tests for intrathecal inflammation (p < 0.001 for all comparisons). KFLC and LFLC were significantly different in patients with MS and CIS compared to the other groups (p < 0.001 and p < 0.001, resp.) and had a better diagnostic accuracy than all the other tests (area under the curve 82.3 % for KFLC index and 79.3 % for LFLC index). Conclusion. Nephelometric assays for KFLC in CSF reliably detect intrathecal immunoglobulin synthesis and discriminate MS patients.
Solutions of polynomial systems derived from the steady cavity flow problem

We propose a general algorithm to approximately enumerate all solutions of a zero-dimensional polynomial system with respect to a given cost function. The algorithm is developed and is used to study a polynomial system obtained by discretizing the steady cavity flow problem in two dimensions. The key technique on which our algorithm is based is to solve polynomial optimization problems via sparse semidefinite program relaxations (SDPR), which has been adopted successfully to solve reaction-diffusion boundary value problems recently. The cost function to be minimized is derived from discretizing the kinetic energy of the fluid. The solutions of the enumeration algorithm are shown to converge to the minimal kinetic energy solutions for SDPR of increasing order. We take advantage of Groebner basis method to tune the performance of the algorithm, demonstrate the algorithm with SDPR of first and second order on polynomial systems for different scenarios of the cavity flow problem and succeed in approximately deriving the k smallest kinetic energy solutions. The question of whether these solutions converge to solutions of the steady cavity flow problem is discussed, and we pose a conjecture for the minimal energy solution for increasing Reynolds number.
The relationship between EFL learners' self-efficacy and their social-affective strategy use across years of study

The present study investigated the relationship between self-efficacy and social-affective strategy use of EFL learners across years of study. To this end, 170 male and female undergraduate students were selected through convenience sampling. The instruments included Self-Efficacy for Learning Form (SELF-A) and the social-affective section of the Strategy Inventory for Language Learning (SILL). Chi-square test and Spearman rank-order correlation were run to examine the relationship between the variables. The result indicated that there was no relationship between self-efficacy and year of study. Moreover, no relationship was found between the participants’ social-affective strategy use and year of study. However, there was a significant positive relationship between self-efficacy and social-affective strategy across third and fourth years of study.
On the coverage of space by random sets

Let ξ1, ξ2,… be a Poisson point process of density λ on (0,∞) d , d ≥ 1, and let ρ, ρ1, ρ2,… be i.i. d. positive random variables independent of the point process. Let C := ⋃ i≥1 {ξ i + [0,ρ i ] d }. If, for some t > 0, (0,∞) d ⊆ C, then we say that (0,∞) d is eventually covered by C. We show that the eventual coverage of (0,∞) d depends on the behaviour of xP(ρ > x) as x → ∞ as well as on whether d = 1 or d ≥ 2. These results may be compared to those known for complete coverage of ℝ d by such Poisson Boolean models. In addition, we consider the set ⋃{i≥1:X i =1} [i,i+ρ i ], where X 1, X 2,… is a {0,1}-valued Markov chain and ρ1, ρ2,… are i.i. d. positive-integer-valued random variables independent of the Markov chain. We study the eventual coverage properties of this random set.
Efficacy of Quinidine in High-Risk Patients With Brugada Syndrome

Background—Automatic implantable cardioverter-defibrillator therapy is considered the only effective treatment for high-risk patients with Brugada syndrome. Quinidine depresses Ito current, which may play an important role in the arrhythmogenesis of this disease. Methods and Results—The effects of quinidine bisulfate (mean dose, 1483±240 mg) on the prevention of inducible and spontaneous ventricular fibrillation (VF) were prospectively evaluated in 25 patients (24 men, 1 woman; age, 19 to 80 years) with Brugada syndrome. There were 15 symptomatic patients (including 7 cardiac arrest survivors and 7 patients with unexplained syncope) and 10 asymptomatic patients. All 25 patients had inducible VF at baseline electrophysiological study. Quinidine prevented VF induction in 22 of the 25 patients (88%). After a follow-up period of 6 months to 22.2 years, all patients are alive. Nineteen patients were treated with quinidine for 6 to 219 months (mean±SD, 56±67 months). None had an arrhythmic event, although 2 had non–arrhythmia-related syncope. Administration of quinidine was associated with a 36% incidence of side effects that resolved after drug discontinuation. Conclusions—Quinidine effectively prevents VF induction in patients with Brugada syndrome. Our data suggest that quinidine also suppresses spontaneous arrhythmias and could prove to be a safe alternative to automatic implantable cardioverter-defibrillator therapy for a substantial proportion of patients with Brugada syndrome. Randomized studies comparing these two therapies seem warranted.
Design techniques for low-voltage high-speed digital bipolar circuits

This paper describes design techniques for multigigahertz digital bipolar circuits with supply voltages as low as 1.5 V. Examples include a 2/1 multiplexer operating at 1 Gb/s with 1.2 mW power dissipation, a D-latch achieving a maximum speed of 2.2 GHz while dissipating 1.4 mW, two exclusive-OR gates with a delay less than 200 ps and power dissipation of 1.3 mW, and a buffer/level shifter having a delay of 165 ps while dissipating 1.4 mW. The prototypes have been fabricated in a 1.5-/spl mu/m 12-GHz bipolar technology. Simulations on benchmarks such as frequency dividers and line drivers indicate that, for a 1.5-V supply, the proposed circuits achieve higher speed than their CMOS counterparts designed in a 0.5-/spl mu/m CMOS process with zero threshold voltage. >
The Effect of Service Quality on Student Satisfaction and Student Loyalty: An Empirical Study.

The aim of this research is to examine the influence of service quality on student satisfaction and student loyalty at higher education institutions in Riau Province. The samples include 1,000 students from 13 universities and colleges in Riau Province. The exogenous variable is service quality while the endogenous variables are student satisfaction and student loyalty. Analytical tool used in this study were Structural Equation Modeling (SEM) and Analysis of Variance (ANOVA) along with SPSS21 and AMOS 21. The result indicated a significant positive influence of service quality towards student satisfaction and significant positive influence on student satisfaction towards student loyalty. Nevertheless, there is no significant and positive influence on the relationship between service quality and student loyalty.
Activating Cross-Boundary Knowledge: The Role of Simmelian Ties in the Generation of Innovations

In this article, we study the conditions under which having ties that span organizational boundaries (bridging ties) are conducive to the generation of innovations. Whereas previous research has shown that bridging ties have a positive impact on innovative performance, our analysis of 276 R&D scientists and engineers reveals that there are no advantages associated with bridging per se. In contrast, our findings suggest that the advantages traditionally associated with bridging ties are contingent upon the nature of the ties forming the bridge—specifically, whether these bridging ties are Simmelian.
Generating continuous mappings with Lipschitz mappings

If X is a metric space, then C X and £ X denote the semigroups of continuous and Lipschitz mappings, respectively, from X to itself. The relative rank of C X modulo £ X is the least cardinality of any set U £ X where U generates C X . For a large class of separable metric spaces X we prove that the relative rank of C X modulo £ X is uncountable. When X is the Baire space N N , this rank is 8 1 . A large part of the paper emerged from discussions about the necessity of the assumptions imposed on the class of spaces from the aforementioned results.
Kefungsian Keluarga dan Perkaitannya dengan Motivasi Pencapaian: Satu Kajian di Kementerian Sumber Manusia

Family functioning and achievement motivation are two aspects that have been frequently discussed by psychologists. Findings from previous research found that both aspects are related to each other. The objective of this research was to identify the levels of family functioning and motivation achievements among civil servants from the Ministry of Human Resources. Besides that, this research intended to observe the influence of family functioning towards motivation achievement of the same sample. This research involved 945 respondents comprised of employees with different grades and position within the Ministry of Human Resource in which they were chosen via simple random sampling. The Family Functioning Style Scale (FFSS) was used to measure family functioning while the Cassidy and Lynn Achievement Scale (CLAM) was used to measure achievement motivation. Analysis was carried out using Statistical Package for Social Science (SPSS) version 22 on the data collected. Results showed that majority of the respondents were found to have high levels of family functioning, however, majority of the respondents reported average level of achievement motivation. Results also found that family functioning was influential to motivation achievement.
STRUCTURE AND KINEMATICS OF THE STELLAR HALOS AND THICK DISKS OF THE MILKY WAY BASED ON CALIBRATION STARS FROM SLOAN DIGITAL SKY SURVEY DR7

The structure and kinematics of the recognized stellar components of the Milky Way are explored, based on well-determined atmospheric parameters and kinematic quantities for 32360 “calibration stars” from the Sloan Digital Sky Survey (SDSS) and its first extension, SDSS-II, which included the sub-survey Sloan Extension for Galactic Understanding and Exploration (SEGUE). Full space motions for a sub-sample of 16,920 stars, exploring a local volume within 4 kpc of the Sun, are used to derive velocity ellipsoids for the inner- and outer-halo components of the Galaxy, as well as for the canonical thick-disk and proposed metal-weak thick-disk (MWTD) populations. This new sample of calibration stars represents an increase of 60% relative to the numbers used in a previous analysis. We first examine the question of whether the data require the presence of at least a two-component halo in order to account for the rotational behavior of likely halo stars in the local volume, and whether more than two components are needed. We also address the question of whether the proposed MWTD is kinematically and chemically distinct from the canonical thick disk, and point out that the Galactocentric rotational velocity inferred for the MWTD, as well as its mean metallicity, appear quite similar to the values derived previously for the Monoceros stream, suggesting a possible association between these structures. In addition, we consider the fractions of each component required to understand the nature of the observed kinematic behavior of the stellar populations of the Galaxy as a function of distance from the plane. Scale lengths and scale heights for the thick-disk and MWTD components are determined. Spatial density profiles for the inner- and outer-halo populations are inferred from a Jeans theorem analysis. The full set of calibration stars (including those outside the local volume) is used to test for the expected changes in the observed stellar metallicity distribution function with distance above the Galactic plane in situ, due to the changing contributions from the underlying stellar populations. The above issues are considered, in concert with theoretical and observational constraints from other Milky-Way-like galaxies, in light of modern cold dark matter galaxy formation models.
Quantum Isomonodromic Deformations and the Knizhnik--Zamolodchikov Equations

Viewing the Knizhnik--Zamolodchikov equations as multi--time, nonautonomous Shr\"odinger equations, the transformation to the Heisenberg representation is shown to yield the quantum Schlesinger equations. These are the quantum form of the isomonodromic deformations equations for first order operators of the form $\DD_\l = {\di \over \di \l} - \wh{\NN}(\l)$, where $\wh{\NN}(\l)$ is a rational $r\times r$ matrix valued function of $\l$ having simple poles only, and the matrix entries are interpreted as operators on a module of the rational $R$--matrix loop algebra $\wt{\frak{gl}}(r)_R$. This provides a simpler formulation of a construction due to Reshetikhin, relating the KZ equations to quantum isomonodromic deformations.
Learning leads to scaling behaviour in an adaptive expectations model of a double-auction market

The field of econophysics has established that empirical financial time series data exhibit several robust scaling laws, but to date there has been relatively little attempt to explain these scaling phenomena. In this paper we explore the scaling of the absolute changes in logarithmic price with respect to the size of the time interval over which they are calculated. In an efficient market, it is straightforward to show how this can arise in a rational expectations model when changes to the fundamental price are driven by a random walk. However it is now well-known that empirical financial time series data do not fit well with geometric Brownian motion at high-frequency time scales. To address this, we model the financial market using a class of agent-based models in which agents’ expectations are driven by heuristic forecasting rules (in contrast to the rational expectations models used in traditional theories of financial markets). We show that within this framework, social learning results in robust scaling behaviour.
