Coronary artery fistula with a giant aneurysm treated by percutaneous transradial embolization

Coronary artery fistulas are rare anomalies that are very rarely accompanied by an aneurysm. The minimally invasive method of percutaneous transradial embolization, using a thin guiding catheter, was used to treat a coronary artery fistula with an associated giant aneurysm. This technique, not previously described for this type of application, is presented as a case report. The successful outcome of this procedure demonstrated that transradial coronary interventions are useful for treating coronary artery fistulas with an associated giant aneurysm, especially in patients at high risk for conventional surgery or transfemoral interventions. © 2012 Wiley Periodicals, Inc.
The Consequences of Perceived Age Discrimination Amongst Older Police Officers: Is Social Support a Buffer?

This paper considers the possible psychological consequences of perceived age discrimination, and the possible buffering effect of social support. Findings, based on a study of perceived age discrimination amongst police officers in the North of England, suggest that age discrimination acts as a stressor, with officers experiencing negative effects of perceived age discrimination on job and life satisfaction, perceived power and prestige of the job, and affective and normative commitment, along with positive effects on withdrawal cognitions and continuance commitment. For work-based social support, there were positive main effects on job and satisfaction, power and prestige of the job, and affective and normative commitment, and a negative main effect on withdrawal cognitions. However, there were no significant moderating effects for work-based social support, and we found the anticipated buffering effect for non-work-based social support only for life satisfaction, with reverse buffering for job satisfaction and normative commitment. The limitations and implications of the study are discussed.
Development of Z‐scores for fetal cardiac dimensions from echocardiography

Z‐scores for cardiac dimensions are well established in postnatal life, but have yet to be developed for fetal cardiac dimensions. These would be of real advantage to the clinician in accurately quantifying size and growth of cardiac dimensions and to the researcher by allowing mathematical comparison of growth in differing subgroups of a disease. The purpose of this observational study, conducted at tertiary fetal medicine and cardiology units, was to produce formulae and nomograms allowing computation of Z‐scores for fetal cardiac dimensions from knowledge of femur length (FL), biparietal diameter (BPD) or gestational age (GA) using fetal echocardiography.
Reading and Reading Impairments

Within the discipline of speech-language pathology, there is an increasing interest in reading and reading impairment as an area of concentration. This trend is recognizable from the professional policy statements that define the roles and responsibilities for clinicians (e.g., american Speech-language-Hearing association, 2001) and from the increased research and intervention publications available regarding literacy service delivery across age ranges and disability types (e.g., Beeson & Henry, 2008; catts et al., 2002; catts & kamhi, 2004; connor & Zwolan, 2004; Gillon, 2002; Iacono & cupples, 2004; lynch et al., in press; mody & Silliman, 2008; norris & Hoffman, 2002). as more societal (Gee, 2000; Goody, 1986; ong, 1982) and educational (cazden et al., 1996; “no child left Behind act of 2001 (H.R.1),” 2002; Strauss, 2005) attention is given to literacy, it has become a more important issue for the practicing clinician. The discipline’s interest in reading, however, is not necessarily matched by the clinicians’ knowledge or perceived competence regarding reading and read ing impairments. a nationwide survey found that the majority of practicing speechlanguage pathologists surveyed indicated that they were not well trained regarding literacy issues and did not have confidence in their abilities to address literacy/ reading as a clinical responsibility (nelson & Damico, 2002). This lack of knowledge and confidence regarding reading is problematic but not surprising. Historically, speech-language pathology evolved with an initial focus on speech and only incorporated an emphasis on language much later in the development of the discipline (Damico, 1993; Duchan, 2008). It is only within the last decade that speechlanguage pathologists have focused on literacy as a clinical issue. consequently, the discipline is less informed about literacy/reading than is desirable (nelson & Damico, 2002), especially since language arts is a complex area fraught with debate. literacy theory and instruction is often controversial. over the past several decades there have been suggestions of the “great debate” in language arts (chall, 1983), the “reading wars” (Goodman, 1998; lemann, 1997) regarding literacy
The effects of educational systems, school-composition, track-level, parental background and immigrants' origin on the achievement of 15-years old native and immigrant students : a reanalysis of PISA 2006

The effects of educational systems, school-composition, track-level, parentalbackground and immigrantsâ€™ origins on the achievement of 15-years old native andimmigrant students. A reanalysis of PISA 2006.The main research question of this paper is the combined estimation of the effectsof educational systems, school-composition and track-level on the educationalachievement of 15-years-old students. We specifically focus on the effects of socioeconomicand ethnic background on achievement scores and to what extent theseeffects are affected by characteristics of the school, track or educational system thesestudents are in. In doing so, we examine the â€˜sortingâ€™ mechanisms of schools and tracksin highly stratified, moderately stratified and comprehensive education systems. Weuse data from the 2006 PISA (Programme for International Student Assessment) wave.Compared to previous research in this area the main contribution of this paper is thatwe explicitly include track-level and school-level as separate units of analyses, whichleads to less biased results of the effects of characteristics of the educational system.The results highlight the importance of including track-level and school-level factorsin the debate of educational inequality of opportunity for students in differenteducation contexts. The findings clearly indicate that the effects of educationalsystem characteristics are flawed if the analysis uses only a country and a studentlevel and ignores the track- and school-level characteristics. Moreover the inclusionof the track-level is necessary to avoid overestimation of the school-compositioneffect, especially in stratified educational systems. From a policy perspective, the mostimportant finding is that educational system are not uniformly â€˜goodâ€™ or â€˜badâ€™, butthey have different consequences for different groups. Some groups are better offin comprehensive systems, while other groups are better off in moderately or highlystratified systems.
Learning Database Abstractions for Query Reformation

The query reformulation approach (also called semantic query optimization) takes advantage of the semantic knowledge about the contents of databases for optimization. The basic idea is to use the knowledge to reformulate a query into a less expensive yet equivalent query. Previous work on semantic query optimization has shown the cost reduction that can be achieved by reformulation, we further point out that when applied to distributed multidatabase queries, the reformulation approach can reduce the cost of moving intermediate data from one site to another. However, a robust and efficient method to discover the required knowledge has not yet been developed. This paper presents an example-guided, data-driven learning approach to acquire the knowledge needed in reformulation. We use example queries to guide the learning to capture the database usage pattern. In contrast to the heuristic-driven approach proposed by Siegel, the data-driven approach is more likely to learn the required knowledge for the various reformulation needs of the example queries. Since this learning approach minimizes the dependency on the database structure and implementation, it is applicable to heterogeneous multidatabase systems. With the learning capability, the query reformulation will be more effective and feasible in real-world database applications.
Diurnal Changes of Zooplankton Community Reduction Rate at Lake Outlets and Related Environmental Factors

The reduced zooplankton abundance at the outlet sections of lakes depends on the occurrence of preying fry. Therefore, light conditions can play a major role in the drift of zooplankton along river outlets. The aim of this study was to determine the influence of diurnal light conditions on the decline of zooplankton densities at lake outlets. Photosynthetically active radiation (PAR) levels were measured to determine their effect on the rate of reduced zooplankton abundance. Cladocerans and copepods showed a significantly greater reduction in abundance than rotifers and nauplii. A significant positive relationship was observed between the PAR levels and the reduced abundance of Asplanchna sp. , small cladocerans, large cladocerans and Copepoda at the lake outlets. Among the rotifers, small pelagic rotifers drifted the farthest at all hours of the day. Large crustaceans, especially the large cladocerans and copepodites and adult copepods, had the lowest chance of dispersing over a wide area. Our results indicate that light conditions play an important role in the reduction of zooplankton abundance at lake outlets and have an indirect influence on the downstream food web.
The QWERTY Effect on the Web: How Typing Shapes the Meaning of Words in Online Human-Computer Interaction

The QWERTY effect postulates that the keyboard layout influences word meanings by linking positivity to the use of the right hand and negativity to the use of the left hand. For example, previous research has established that words with more right hand letters are rated more positively than words with more left hand letters by human subjects in small scale experiments. In this paper, we perform large scale investigations of the QWERTY effect on the web. Using data from eleven web platforms related to products, movies, books, and videos, we conduct observational tests whether a hand-meaning relationship can be found in text interpretations by web users. Furthermore, we investigate whether writing text on the web exhibits the QWERTY effect as well, by analyzing the relationship between the text of online reviews and their star ratings in four additional datasets. Overall, we find robust evidence for the QWERTY effect both at the point of text interpretation (decoding) and at the point of text creation (encoding). We also find under which conditions the effect might not hold. Our findings have implications for any algorithmic method aiming to evaluate the meaning of words on the web, including for example semantic or sentiment analysis, and show the existence of "dactilar onomatopoeias" that shape the dynamics of word-meaning associations. To the best of our knowledge, this is the first work to reveal the extent to which the QWERTY effect exists in large scale human-computer interaction on the web.
OPTIMIZATION WITH FLUTTER AND BUCKLING METRICS ( POSTPRINT )

This work develops a framework for SIMP-based topology optimization of a metallic panel structure subjected to design-dependent aerodynamic, inertial, elastic, and thermal loads. Multi-physics eigenvalue-based design metrics such as thermal buckling and dynamic flutter are derived, along with their adjoint-based design derivatives. Locating the flutter point (Hopf-bifurcation) in a precise and efficient manner is a particular challenge, as is outfitting the optimization problem with sufficient constraints such that the critical flutter mode does not switch during the design process. Results are presented for flutter-optimal topologies of an unheated panel, thermal buckling-optimal topologies, and flutter-optimality of a heated panel (where the latter case presents a topological compromise between the former two). The effect of various constraint boundaries, temperature gradients, and (for the flutter of the heated panel) thermal load magnitude are assessed. Off-design flutter and thermal buckling boundaries are given as well.
Cross-Layer Design for Video Transmissions in Metro Passenger Information Systems

In metro passenger information systems (PISs), frequent train handoffs can cause severe video distortion. In this paper, we take an integrated design approach to jointly optimize application-layer parameters and handoff decisions to improve video transmission quality over PISs. We present a train-ground video communication network based on fountain codes and IEEE 802.11p for metro PISs. The metro PIS channel is modeled as a finite-sate Markov chain, and the channel-state transition probability matrix is calculated from the data that were measured in real field tests. The handoff decision and application-layer parameters adaptation problem is formulated as a stochastic semi-Markov decision process (SMDP). Minimizing the end-to-end total video distortion is the objective in our model. Simulation results show that the proposed SMDP-based optimization algorithm can significantly improve the end-to-end video transmission quality in metro PISs.
Design of sparse lowpass differentiator using iterative hard thresholding method

In this paper, the design of a sparse digital lowpass differentiator is presented. First, the original iterative hard thresholding (IHT) algorithm in the compressed sensing is used to solve this design problem. Then, a modified IHT algorithm is proposed to improve the performance by using a smooth thresholding technique. Finally, the proposed IHT methods are compared with the conventional orthogonal matching pursuit (OMP) method to show their performance. The main feature of the proposed design methods is that the error of magnitude response and sparsity of filter coefficients can be controlled by suitably choosing the thresholding parameter.
Outcome of severe head injured patients admitted to intensive care during weekday shifts compared to nights and weekends.

INTRODUCTION Some studies have demonstrated an increased risk of death for patients admitted at nights or during weekends. This study was undertaken to investigate the demographic profile, medical interventions and outcome of severe head injury patients stratified according to day and time of admission to a specialised neurosciences intensive care unit (NICU). MATERIALS AND METHODS A retrospective study using a prospectively maintained severe head injury database in a tertiary hospital. Admissions to the NICU were grouped into weekdays, weeknights and weekends. A comparison of patients admitted during the day and night hours were also made. RESULTS A total of 838 severe head injury patients admitted to NICU were included in the study, of which 263 were admitted on weekdays, 327 on weeknights and 248 on weekends. More patients were admitted during the night (496) compared to during the day (342). There were no significant differences in the demographic profile, mechanism of injury, severity of injury, need for neurosurgical intervention, and duration of mechanical ventilation, intensive care unit (ICU) stay and mortality associated with day and time of admission. In multivariate analyses controlling for confounding factors, no statistically significant difference in ICU mortality was found with the day and time of admission. CONCLUSIONS There were more severe head injury patients admitted to ICU at night and on weekends, with no significant difference in demographic profile, types of injuries, need for neurosurgical interventions and duration of ICU stay and mortality in a specialised NICU with adequate staffing and requisite diagnostic and therapeutic modalities available.
Empirically Derived Guidelines for Multimodal Interaction in Knowledge-Based Environments

The development of multimodal user interfaces is a complex process that needs useful guidelines and hints. This paper summarizes the overall results from a previous experimental program and then suggests useful guidelines for creating usable and acceptable knowledge-based system (KBS) interfaces. The summary of the overall experimental results ranks three experimental conditions of multimodal interaction, according to five evaluation domains. These domains were: ability to recall, ability to use knowledge effectively, ability to use knowledge efficiently, extended usability attitudes and user acceptance. The proposed guidelines offer a set of useful hints while also describing the sources of the variance between the experimental conditions. The empirically derived and proposed guidelines were: knowledge communication from a single point of contact, audio-visual metaphors to tackle information overload, task complexity and knowledge-intensity as key factors, and socially rich presence which allowed for the first impression to last longer. These guidelines have presented a roadmap for both researchers and practitioners working within the field of knowledge-based software engineering (KBSE).
Dehumanization and guilt as distinct but related predictors of support for reparation policies

In two studies, we predicted that support for reparation policies would be influenced positively by feelings of group-based guilt and negatively by dehumanization of the outgroup. We also hypothesized that a valence manipulation of the ingroup's behavior would cause differences in such support which would be mediated by guilt. In the first study, we manipulated the valence of past ingroup behavior and assessed guilt, dehumanization, and reparation support. As expected, guilt predicted positively and dehumanization negatively participants' support. In addition, guilt partially mediated the manipulation effects on policy support. Consistent with previous research, guilt and dehumanization were unrelated. In Study 2, we assessed individual differences in dehumanization before the manipulation and examined their associations with guilt and reparation support. Initial analyses replicated Study 1. In addition, guilt partially mediated the influence of dehumanization on reparation support. Results suggest that the presence of guilt motivates support for reparation policies, while the absence of guilt explains in part why individual differences in dehumanization inhibit such support.
Expression of Ezrin correlates with lung metastasis in Chinese patients with osteosarcoma.

PURPOSE To determine the prognostic value of the expression of Ezrin, CD44 and Six1 genes in osteosarcoma tissues of Chinese patients. METHODS Fluorescent quantitative real-time PCR was applied to study the mRNA levels of Ezrin, CD44 and Six1 genes in 32 osteosarcoma patient samples and 10 adjacent normal tissues and MG63 osteosarcoma cell lines. The analysis of relationships between pulmonary metastasis and overall survival time were carried out based on the clinical data. RESULTS mRNA levels of Ezrin and Six1 genes in osteosarcoma tissues were higher than those in adjacent normal tissues (P=0.015, 0.025). The mRNA levels of Ezrin, CD44 and Six1 genes were closely correlated with Enneking GTM clinical staging, while no correlations were demonstrated between the mRNA level of these genes with sex, age, location or pathological types. In addition, we demonstrated that the high mRNA level of Ezrin gene was related to shorter lung metastasis-free and overall survival time of the Chinese patients with osteosarcoma (P < 0.001). CONCLUSION Our data suggest that Ezrin, but not CD44 and Six1, could be a prognostic factor and a predictor of potential lung metastasis in osteosarcoma. Further large sample studies need to be done to confirm the potential value of Ezrin as a new therapeutic target.
APPROXIMATING SPECTRAL INVARIANTS OF HARPER OPERATORS ON GRAPHS II

We study Harper operators and the closely related discrete magnetic Laplacians (DML) on a graph with a free action of a discrete group, as defined by Sunada. The spectral density function of the DML is defined using the von Neumann trace associated with the free action of a discrete group on a graph. The main result in this paper states that when the group is amenable, the spectral density function is equal to the integrated density of states of the DML that is defined using either Dirichlet or Neumann boundary conditions. This establishes the main conjecture in a paper by Mathai and Yates. The result is generalized to other self adjoint operators with finite propagation speed.
Using spectrograms in EMI-analysis - an overview

Spread-spectrum techniques have raised their importance as a common EMI-reduction technique in power supplies. Ability to track and measure such a signal is vital. Analysis and synthesis of an effective spread-spectrum sequence is also important. Pulse-type and apparently random interference are other types of signals which are hard to detect and measure, but still very common in practice. In this paper a spectrogram, a time-dependent spectrum analysis is proposed as a practical tool for EMC-design and measurements. Basic theory and selected examples of spectrogram in EMC-engineering are presented.
Using Structural Equation Modeling to Explore Saudi Consumers’ Intentions Regarding Counterfeit Goods

Although the Saudi Customs Department attempts to prevent the import and/or export of counterfeit goods more than 62 million counterfeit products, with a value of approximately US$50 million, were confiscated at ports in Saudi Arabia over the past year in 2012. This paper focuses on the key antecedents of Saudi consumer attitudes toward counterfeit products, as well as the influence that these attitudes have on the Saudi behavioral intentions regarding these products. A 10 min pen and structured questionnaire was distributed to 520 subjects in Riyadh through a nonprobability, convenience-sampling approach to test the hypothesized relationships using structural equation model (SEM) test with maximum likelihood estimation. The empirical results from the structural model suggest that: Saudi consumer intentions to buy counterfeited products are influenced by perceived risk, subjective norm, price-quality inference, prior purchase of counterfeits, integrity, and personal gratification. The paper reinforces the mediator role that attitude plays in the relationship between these antecedents and behavioral intentions. Furthermore, a consumer’s previous experience with consumption of counterfeits does not have a direct effect on behavioral intentions; only an indirect effect through attitude. This paper informs policy makers and brand managers about the main predictors of consumer’s attitudes toward counterfeits. In this way, advertisements that are intended to discourage the consumption of counterfeits could use the perceived risk as their primary message.
