Localized Tight Frames on Spheres

In this paper we wish to present a new class of tight frames on the sphere. These frames have excellent pointwise localization and approximation properties. These properties are based on pointwise localization of kernels arising in the spectral calculus for certain self-adjoint operators, and on a positive-weight quadrature formula for the sphere that the authors have recently developed. Improved bounds on the weights in this formula are another by-product of our analysis.
Number of Magic Squares from Parallel Tempering Monte Carlo

There are 880 magic squares of size 4 by 4, and 275 305 224 of size 5 by 5. It seems very difficult if not impossible to count exactly the number of higher order magic squares. We propose a method to estimate these numbers by Monte Carlo simulating magic squares at finite temperature. One is led to perform low temperature simulations of a system with many ground states that are separated by energy barriers. The Parallel Tempering Monte Carlo method turns out to be of great help here. Our estimate for the number of 6 by 6 magic squares is (0.17745± 0.00016)×1020.
Information Technology Project-based Organizations and Employee Satisfaction: A Case Study of Iran

2 Abstract: This paper's main focus is on the employee satisfaction as one the most sought after subjects in today's IT project-based organizations. It provides an empirical examination of the relationship between job satisfaction and the degree of dependence on IT tools to complete job tasks.210 questionnaires were distributed among respondents to study this relationship based on the model of 4 constructs to measure the effects of "computing environment", "organization environment" and "job characteristics" on "job satisfaction" by applying structural equation modelling. The results strongly support the extended model and conclude with implications for practitioners and recommendations for future researches.
Coping self-efficacy and psychological distress in flood victims

Book Description: Life is a mix of good and bad happenings and sometimes terrible things happen to people. Trauma is evident across our lifespan; it is part of our lives. Trauma may not exert the same demands on the individual when they get on with their lives or experience other positive aspects of what life has to offer; however, it does not change its form from trauma to growth – it stays there etched into our psyche as trauma. In simple terms, growth occurs alongside the traumatic etchings. This is a book that will provide some answers to psychologists, counselors, social workers and mental health workers about what happens to people who are traumatized and how they ‘get on with their lives’; it also gives some excellent examples of how therapies can assist them in moving forward in life’s journey.
Towards actor/actress identification in drama videos

This paper addresses to achieve an automated actor/actress annotation system for drama videos. As key technologies, face sequence extraction and matching methods applicable to actual drama videos are presented. The methods are then applied to realize a semi-automated actor/actress annotation system. After the system is trained using an episode of a drama series by given several tens of manual annotations to face sequences, it can automatically annotate face sequences not only of the trained episode, but of the other episodes of the drama series. Experimental results show that the system achieves around 70% accuracy in face sequence annotation using 40 manual annotations as the training set.
Lexical and Translation Equivalence in Parallel Corpora

In the present paper we intend to investigate to what extent use of parallel corpora can help to eliminate some of the difficulties noted with bilingual dictionaries. The particular issues addressed are the bidirectionality of translation equivalence, the coverage of multiword units, and the amount of implicit knowledge presupposed on the part of the user in interpreting the data. Three lexical items belonging to different word classes were chosen for analysis: the noun head, the verb give and the preposition with. George Orwell's novel 1984 was used as source material, which is available in English-Hungarian sentence aligned form. It is argued that the analysis of translation equivalents displayed in sets of concordances with aligned sentences in the target language holds important implications for bilingual lexicography and automatic word alignment methodology.
Fairness-guaranteed pricing and power allocation with a friendly jammer against eavesdropping

In wireless communication, jamming is a promising solution to provide improvement in secrecy rate, especially when security requirement is difficult to satisfy in realistic environment. Users could pay the friendly jammer for some interference to the eavesdropper and consequently improve the secrecy rate of their own, while the jammer wants to get maximum revenue within its capability. Thereby a Stackelberg game is introduced. Fairness also deserves particular attention, as unfair allocation of the limited resource deteriorates the performance of whole network. In this paper, we discuss a network with one jammer and several users, where they participate in the game and reach equilibrium ultimately. We utilize Kalai-Smorodinsky bargaining solution to guarantee fairness among users, making them balance their utility so as to make the best of the interference from the jammer. Moreover, we propose implementation of algorithm and demonstrate the performance.
Comparative Analysis of Preservice Teachers' Reflective Thinking in Synchronous Versus Asynchronous

This study was undertaken to better understand the nature of preservice teachers' reflective thinking during case discussions about classroom management in two online formats: synchronous versus asynchronous. Findings indicated that when participants engaged in synchronous online case discussions they had higher levels of critical reflection than when they engaged in asynchronous online case discussions. Also, participants' initial preferences for asynchronous discussions changed from the beginning to the end of this study. Reasons for changes in participants' format preferences and descriptions of participants' levels of critical reflection are discussed.

The present research has as objective the elaboration of a procedure to develop studies about the organizational behavior and it integrates variables according to the organization ́s requirements. The procedure has four phases and seven steps; all of them focused en improvement actions, therefore a bibliographical search was carried out to support the proposal. Different theatrical and empirical methods were explained, such as, analysis and synthesis, induction-deduction, check list, Delphi method, surveys, interviews, group work method, and lessons classification, all these methods were support by computing applications that allow to validate instruments. The procedure implementation is presented for the study of the organizational behavior in a PYME that commercializes dairy products
A novel deterministic method for large-scale blind source separation

A novel deterministic method for blind source separation is presented. In contrast to common methods such as independent component analysis, only mild assumptions are imposed on the sources. On the contrary, the method exploits a hypothesized (approximate) intrinsic low-rank structure of the mixing vectors. This is a very natural assumption for problems with many sensors. As such, the blind source separation problem can be reformulated as the computation of a tensor decomposition by applying a low-rank approximation to the tensorized mixing vectors. This allows the introduction of blind source separation in certain big data applications, where other methods fall short.
Parametrization of MIMO multi-controller schemes for bumpless switching

In this paper the realization and implementation of a multi-controller scheme made of a finite set of linear multiple-input-multiple-output controllers, possibly having different state dimensions, is considered. The problem of bumpless switching between the active controller acting in closed-loop and another controller in the set of controllers waiting to take over the control loop is addressed. A non minimal parametrization of the set of controllers such that all controllers share the same state variables is presented, and it is shown that such a parametrization guarantees bumpless switching between any two controllers within the controller set.
Time-optimal coordination of mobile robots along specified paths

In this paper, we address the problem of time-optimal coordination of mobile robots under kinodynamic constraints along specified paths. We propose a novel approach based on time discretization that leads to a mixed-integer linear programming (MILP) formulation. This problem can be solved using general-purpose MILP solvers in a reasonable time, resulting in a resolution-optimal solution. Moreover, unlike previous work found in the literature, our formulation allows an exact linear modeling (up to the discretization resolution) of second-order dynamic constraints. Extensive simulations are performed to demonstrate the effectiveness of our approach.
Constraints in Computational

Research reported in this paper a) extends the familiar notions of constraints and preferences in computational semantic analysis and generation; b) adapts constraint satisfaction techniques to the requirements of natural language processing; and c) combines i) large-scale static knowledge sources (grammars, ontologies and lexicons) with ii) processing algorithms and iii) an advanced control architecture, which guarantees optimal results in near linear-time. The integration of the above has facilitated the implementation of a semantics-based machine translation system between Spanish, English and Chinese. This paper analyzes constraints and preferences in computational semantics.

Effects of anesthesia and sleep on circulatory response to carotid sinus nerve stimulation.

VATNER, STEPHEN F. , DEAN FRANKLIN, AND EUGENE BRAUNWALD. Effects of anesthesia and sleep on circulatory response to carotid sinus nerve stimulation. Am. J. Physiol. 220(5) : 12491255. 197 l.The effects of electrical stimulation of the carotid sinus nerves on arterial pressure, heart rate, and peripheral blood flows were studied in healthy dogs while conscious, asleep, after general anesthesia with Na pentobarbital, and after autonomic blockade. In the resting conscious dog, 30-set periods of carotid sinus nerve stimulation resulted in average decreases in heart rate of 12 %, arterial pressure 27 %, coronary flow 5 %, mesenteric flow 9 %, and renal flow 8 %, while iliac flow increased by 112 %. In sleeping dogs, the decrease in heart rate (22 %) was greater than when awake. In anesthetized dogs, the decreases in resistance in all beds with stimulation were not as great as in conscious dogs and the periods necessary for arterial pressure and heart rate to return to control following stimulation were prolonged. The bradycardia was mediated predominantly by the vagus nerves in conscious dogs and by the sympathetic nerves in anesthetized dogs. Thus, when compared to conscious dogs, baroreceptor stimulation in anesthetized dogs resulted in less peripheral vasodilatation, slower recovery of arterial pressure and heart rate, and a different pattern of autonomic control of heart rate.
Mumps Antibody Response in Young Adults After a Third Dose of Measles-Mumps-Rubella Vaccine

Baseline mumps antibody titers were high-seropositive for 93.4% of subjects, low-seropositive for 5.8%, and seronegative for <1%. One month after a third measles-mumps-rubella vaccine dose, mumps titers had a modest but significant increase. One year later, titers returned to near baseline.
Fluoroscopy-Free Pulmonary Vein Isolation in Patients with Atrial Fibrillation and a Patent Foramen Ovale Using Solely an Electroanatomic Mapping System

Introduction The advent of electroanatomical mapping (EAM) systems for pulmonary vein isolation (PVI) has dramatically decreased radiation exposure. However, the need for some fluoroscopy remains for obtaining left atrial (LA) access. The aim was to test the feasibility of fluoroscopy-free PVI in patients with atrial fibrillation (AF) and a patent foramen ovale (PFO) guided solely by an EAM system. Methods Consecutive patients with AF undergoing PVI and documented PFO were studied. An EAM-guided approach without fluoroscopy and ultrasound was used. After completing the map of the right atrium, the superior vena cava and the coronary sinus, a catheter pull-down to the PFO was performed allowing LA access. The map of the LA and subsequent PVI was also performed without fluoroscopy. Results 30 patients [age 61±12 years, 73% male, ejection fraction 0.64 (0.53–0.65), LA size in parasternal long axis 38±7 mm] undergoing PVI were included. The time required for right atrial mapping including transseptal crossing was 9±4 minutes. Total procedure time was 127±37 minutes. Fluoroscopy-free PVI was feasible in 26/30 (87%) patients. In four patients, fluoroscopy was needed to access (n = 3) or to re-access (n = 1) the LA. In these four patients, total fluoroscopy time was 5±3 min and the DAP was 14.9±13.4 Gy*cm2. Single-procedure success rate was 80% (24/30) after a median follow-up of 12 months. Conclusion In patients with a documented PFO, completely fluoroscopy-free PVI is feasible in the vast majority of cases.
How good is your Super-Resolution Image? Quality assurance in image reconstruction using the bootstrap

Super-Resolution Image Reconstruction is known to be sensitive to errors in assumptions such as accurate sub-pixel motion estimation. Even small errors can yield a significant degradation of image quality that complicates any follow-on task such as object detection or classification. We focus on the problem of automatic quality assessment of Super-Resolution image reconstruction. We propose a bootstrap-based method that provides an objective metric quantifying reconstruction quality and thus allowing to readjust the reconstruction.
The Diversifying Experience Model: Taking a Broader Conceptual View of the Multiculturalism–Creativity Link

We examine the multiculturalism–creativity link from the perspective of diversifying experiences research. Multicultural experiences can be construed as diversifying experiences—highly unusual and unexpected events or situations (e.g., unusual educational experiences, early life adversity) that push individuals outside the frameworks of their ordinary everyday lives, forcing them to embrace new and uncommon ideas. Our review identifies a range of diversifying experiences (e.g., multicultural exposure, unexpected adversity, violations of expectations) that have been found to influence creativity. We introduce the Diversifying Experience Model (DEM), where we argue for a curvilinear relationship between diversifying experiences and creativity, whereby creativity improves as a result of moderate (but not low or high) levels of diversifying experiences. We also propose adaptive personal resources as the key moderator, and threat and challenge appraisals as the key mediators of the diversifying experience–creativity relation. When adaptive resources are high, moderate diversifying experiences are appraised primarily as a challenge, facilitating creativity, whereas when adaptive resources are low, moderate diversifying experiences are appraised primarily as a threat, derailing creativity. This broad and parsimonious theoretical framework can help clarify and expand research on when and why various diversifying experiences (including multicultural experiences) facilitate creativity.
Stimulation of microbial nitrogen cycling in aquatic ecosystems by benthic macrofauna: mechanisms and environmental implications

Invertebrate animals that live at the bottom of aquatic ecosystems (i.e., benthic macrofauna) are impor- tant mediators between nutrients in the water column and microbes in the benthos. The presence of benthic macro- fauna stimulates microbial nutrient dynamics through differ- ent types of animal-microbe interactions, which potentially affect the trophic status of aquatic ecosystems. This review contrasts three types of animal-microbe interactions in the benthos of aquatic ecosystems: (i) ecosystem engineering, (ii) grazing, and (iii) symbiosis. Their specific contributions to the turnover of fixed nitrogen (mainly nitrate and ammo- nium) and the emission of the greenhouse gas nitrous oxide are evaluated. Published data indicate that ecosystem engineering by sediment-burrowing macrofauna stimulates benthic nitrifica- tion and denitrification, which together allows fixed nitrogen removal. However, the release of ammonium from sediments is enhanced more strongly than the sedimentary uptake of nitrate. Ecosystem engineering by reef-building macrofauna increases nitrogen retention and ammonium concentrations in shallow aquatic ecosystems, but allows organic nitrogen removal through harvesting. Grazing by macrofauna on ben- thic microbes apparently has small or neutral effects on ni- trogen cycling. Animal-microbe symbioses provide abun- dant and distinct benthic compartments for a multitude of nitrogen-cycle pathways. Recent studies reveal that ecosys- tem engineering, grazing, and symbioses of benthic macro- fauna significantly enhance nitrous oxide emission from shallow aquatic ecosystems. The beneficial effect of benthic macrofauna on fixed nitro- gen removal through coupled nitrification-denitrification can thus be offset by the concurrent release of (i) ammonium that stimulates aquatic primary production and (ii) nitrous oxide that contributes to global warming. Overall, benthic macro- fauna intensifies the coupling between benthos, pelagial, and atmosphere through enhanced turnover and transport of ni- trogen.
Regulatory factor X1 is a new tumor suppressive transcription factor that acts via direct downregulation of CD44 in glioblastoma.

BACKGROUND The biological functions of regulatory factor (RF)X1, a transcription factor, are not known. Since the RFX1 gene is often epigenetically silenced and clusters of differentiation (CD)44 proteins that regulate cancer cell biology are increased in human glioblastomas, we designed this study to determine whether RFX1 could regulate CD44 expression in glioblastoma. METHODS Regulatory factor X1 was overexpressed in 4 human glioblastoma cell lines. CD44 expression and cell proliferation, apoptosis, and invasion were assayed under in vitro conditions. In vivo growth of human glioblastoma xenografts was determined in mice. The expression of RFX1 and CD44 in human glioblastoma tissues was quantified. RESULTS A putative RFX1 binding sequence existed in the first exon of the human CD44 gene. The transcription activity of the DNA fragment containing this putative sequence was decreased in cells overexpressing RFX1. Regulatory factor X1 bound to the CD44 gene in glioblastoma cells. It reduced CD44 expression and activated Akt and extracellular signal-regulated kinase, signaling molecules downstream of CD44 to regulate cell proliferation and survival. Overexpression of RFX1 inhibited the survival, proliferation, and transwell invasion of glioblastoma cells and in vivo growth of human glioblastoma xenografts. CD44 overexpression reversed RFX1 effects on cell proliferation. Finally, CD44 protein levels were inversely correlated with RFX1 protein levels in human glioblastoma tissues. CONCLUSIONS These results suggest that RFX1 directly regulates CD44 expression. This mechanism may contribute to RFX1's effects on proliferation, survival, and invasion of glioblastoma cells. Our results provide initial evidence that RFX1 may be an important target/regulator of the malignancy of glioblastoma.
Table 5 Instrument Robustness Factor Analysis : All Political Variables and Persson ’ s ( 2004 ) Political Institutions

The hallmark of the recent development and growth l iterature is the quest to identify institutions that explain significant portions of the observed d ifferences in living standards. There are two drawbacks to the prominent approaches that focus ei ther on the global sample, or on developing nations. First, it is unclear whether the identifi ed institutions also hold explanatory power in advanced countries. Second, it is unclear whether the identified institutions matter to the same degree across all countries, or whether perhaps an al together different set of institutions matters in advanced countries. To address these issues, we exa mine parameter heterogeneity in prominent approaches to institutions and economic performance . We find that parameter heterogeneity is so strong that it requires a new set of instruments to control for endogeneity. At the same time, however, we confirm that a common set of economical ly important institutions does exist among advanced and developing nations. The impact of thes e institutions is shown to vary substantially across subsamples; they are about three times more i portant in developing countries than in OECD countries.
The Design and Implementation of Distributed, Disconnected Operation in PRCS

Traditional client-server version control applications have not addressed the need for disconnected operation. This mode of operation, applied to version control, allows users to use the version control utility to its fullest extent when disconnected from a shared repository. Version control applications demonstrate several features unique to read-only media that virtually eliminates changes to the operational model. The user is presented with the same interface, regardless of network connectivity, and changes in connectivity present themselves as the same operation one expects a version control utility to support, merge or update.
