Incidence, predictors, and 30-day outcomes of new-onset atrial fibrillation after primary percutaneous coronary intervention: insight into the RISK-PCI trial

ObjectivesLimited data exist about the prognostic significance of new-onset atrial fibrillation (AF) after contemporary primary percutaneous coronary intervention (pPCI). The objective of this study was to identify the incidence and predictors of new-onset AF and associated adverse 30-day outcomes in AF patients who underwent pPCI. MethodsWe analyzed 2096 patients undergoing pPCI after pretreatment with 600 mg clopidogrel. Composite 30-day major adverse cardiovascular events were the primary end point. A logistic regression model was developed to identify risk factors for the occurrence of AF and prediction of its impact on 30-day outcomes. ResultsAF occurred in 6.2% of patients. Older age, Killip >1 heart failure at admission, systolic blood pressure of greater than 100 mmHg at admission, creatinine clearance greater than 60 ml/min, preprocedural infarction-related artery occlusion and postprocedural thrombolysis in myocardial infarction flow less than 3 were identified as independent predictors of the occurrence of AF. Rates of 30-day major adverse cardiovascular events [adjusted odds ratio (OR) 2.39, 95% confidence interval (CI): 1.47–3.87] and 30-day death (adjusted OR 2.67, 95% CI: 1.46–4.89) were higher in AF patients compared with patients without AF. A trend toward higher rate of ischemia-driven target vessel revascularization was observed in the AF group (adjusted OR 2.61, 95% CI: 0.82–8.39, P=0.10). ConclusionNew-onset AF after pPCI is associated with adverse 30-day outcomes. Accurate prediction of AF after pPCI might help deciding a more aggressive treatment approach aimed at preventing the adverse prognosis of these patients.
Antioxidant vitamin intake and coronary mortality in a longitudinal population study.

Oxidation of lipoproteins is hypothesized to promote atherosclerosis and, thus, a high intake of antioxidant nutrients may protect against coronary heart disease. The relation between the intakes of dietary carotene, vitamin C, and vitamin E and the subsequent coronary mortality was studied in a cohort of 5,133 Finnish men and women aged 30-69 years and initially free from heart disease. Food consumption was estimated by the dietary history method covering the total habitual diet during the previous year. Altogether, 244 new fatal coronary heart disease cases occurred during a mean follow-up of 14 years beginning in 1966-1972. An inverse association was observed between dietary vitamin E intake and coronary mortality in both men and women with relative risks of 0.68 (p for trend = 0.01) and 0.35 (p for trend < 0.01), respectively, between the highest and lowest tertiles of the intake. Similar associations were observed for the dietary intake of vitamin C and carotenoids among women and for the intake of important food sources of these micronutrients, i.e., of vegetables and fruits, among both men and women. The associations were not attributable to confounding by major nondietary risk factors of coronary heart disease, i.e., age, smoking, serum cholesterol, hypertension, or relative weight. The results support the hypothesis that antioxidant vitamins protect against coronary heart disease, but it cannot be excluded that foods rich in these micronutrients also contain other constituents that provide the protection.
Acoustic modelling of American English /r/

Recent advances in physiological data collection methods have made it possible to test the accuracy of predictions against speaker-specific vocal tracts and acoustic patterns. Vocal tract dimensions for /r/ derived via magnetic-resonance imaging (MRI) for two speakers of American English [Alwan, Narayanan, and Haker, J. Acoust. Soc. Am. 101, 1078-1089 (1997)] were used to construct models of the acoustics of /r/. Because previous models have not sufficiently accounted for the very low F3 characteristic of /r/, the aim was to match formant frequencies predicted by the models to the full range of formant frequency values produced by the speakers in recordings of real words containing /r/. In one set of experiments, area functions derived from MRI data were used to argue that the Perturbation Theory of tube acoustics cannot adequately account for /r/, primarily because predicted locations did not match speakers' actual constriction locations. Different models of the acoustics of /r/ were tested using the Maeda computer simulation program [Maeda, Speech Commun. 1, 199-299 (1982)]; the supralingual vocal-tract dimensions reported in Alwan et al. were found to be adequate at predicting only the highest of attested F3 values. By using (1) a recently developed adaptation of the Maeda model that incorporates the sublingual space as a side branch from the front cavity, and by including (2) the sublingual space as an increment to the dimensions of the front cavity, the mid-to-low values of the speakers' F3 range were matched. Finally, a simple tube model with dimensions derived from MRI data was developed to account for cavity affiliations. This confirmed F3 as a front cavity resonance, and variations in F1, F2, and F4 as arising from mid- and back-cavity geometries. Possible trading relations for F3 lowering based on different acoustic mechanisms for extending the front cavity are also proposed.
Targets of Opportunity: Organizational and Environmental Determinants of Gender Integration within the California Civil Service, 1979-1985

This paper links organizational change to social inequality by examining how organizational dynamics affected rates of gender integration among California states agencies between 1979 and 1985. The analysis draws on theories of organizations and organization environment relations to identify factors that influence economic, political, and social pressures for change, the costs of change, and capacities to change in a specific work setting. In conformity with those theories, it is shown that progress toward gender integration has been substantially influenced by the degree of external pressure and bulnerability, the relative sizes of various internal interest groups (e.g., women, nonwhites, unions) that favor or oppose integration, the extent of structural inertia to which an organization is prone by virtue of its size and age, and by characteristics of agency leadership. Some implications of these results for studies of organizations and of social inequality are discussed.
Eliminating the feature [lateral]

ABSTRACT The feature [lateral] has a very limited morphophonemic or classificatory role which makes its presence in the universal phonetic feature inventory questionable. A mode of elimination is suggested which involves (i) treating all laterals as [+ distributed]; (ii) limiting [distributed] as a distinctive feature to continuants; (iii) redefining [anterior] in terms of [labial], [apical] and [dental]; (iv) analysing approximant rhotics as glides (Kahn, 1976); (v) adopting Halle and Stevens' re-analysis of [coronal]. This also provides a natural characterization of retroflex sounds and of sibilants. A conceptual problem in child phonology is discussed in the light of the above proposals.
Glucose Attenuation of Auxin-Mediated Bimodality in Lateral Root Formation Is Partly Coupled by the Heterotrimeric G Protein Complex

Background Auxin and glucose are both essential elements in normal root development. The heterotrimeric G protein complex in Arabidopsis thaliana, defined as containing alpha (AtGPA1), beta (AGB1), and gamma (AGG) subunits and a GTPase accelerating protein called Regulator of G Signaling 1 protein (AtRGS1), are involved in glucose signaling and regulate auxin transport. Methodology/Principal Findings A systems approach was used to show that formation of lateral roots, a process requiring coordinated cell division followed by targeted cell expansion, involves a signaling interaction between glucose and auxin. We dissected the relationship between auxin and glucose action using lateral root formation as the biological context. We found that auxin and glucose act synergistically to yield a complex output involving both stimulatory and antagonist glucose effects on auxin responsiveness. Auxin-induced, lateral-root formation becomes bimodal with regard to auxin dose in the presence of glucose. This bimodality is mediated, in part, by the G protein complex defined above. Conclusion/Significance Auxin and glucose are essential signals controlling the rate of cell proliferation and expansion in roots. Auxin promotes the formation of lateral roots and is consequently essential for proper root architecture. Glucose affects the activation state of the heterotrimeric G protein complex which regulates auxin distribution in the root. The bimodality of auxin-induced, lateral-root formation becomes prominent in the presence of glucose and in roots lacking the G protein complex. Bimodality is apparent without added glucose in all loss-of-function mutants for these G protein components, suggesting that the heterotrimeric G protein complex attenuates the bimodality and that glucose inhibits this attenuation through the complex. The bimodality can be further resolved into the processes of lateral root primordia formation and lateral root emergence, from which a model integrating these signals is proposed.
Some Recent Neurophysiological Contributions to the Problem of Brain and Behavior

&NA; The advantages and disadvantages of cellular neurophysiological technics for recording over time the behaviors of waking and sleeping vertebrates, and invertebrates are pointed out, followed by a selective review of the literature on the relationship of brain to behavior. A survey of the influences of sensory input on many regions of the brain is made. Neurophysiological technics were used for the analysis of tactile placing in cats. Intracellular recordings were made for the analysis of a reflex movement which can also occur spontaneously in a mollusk. A review of the neuronal and behavioral consequences of altering visual input and consequently visual experience follows. The paper concludes with a summary of work on the patterning of neuronal activity in different behavioral steady states and the effects of sensory input and movement on this pattern.
Nationalism in German Politics as Mirrored by the Print Media Since Reunification

This article examines nationalist and ethnic attitudes in German politics as illustrated by statements in the print media from members of Germany's political and cultural establishment in the period from the Wiedervereinigung until the present. These sentiments occur across almost the whole political and cultural spectrum and indicate that Germany's political climate has changed. Texts taken from numerous debates demonstrate that, since unification, it has become more and more difficult to draw a clear distinction between national identity and nationalism.
Learning new segments and reducing domains in German L2 phonology: The role of the Prosodic Hierarchy

This paper investigates interactions between the prosodic structures of L1 and L2 in second language acquisition. We focus here on a case in which the L1 and L2 are quite different with regard to the role played by the prosodic structures: the acquisition of German by speakers of Spanish. “Demarcating languages” such as German tend to phonologically mark the beginnings and/ or ends of relatively small prosodic constituents, while “Grouping languages” such as Spanish tend to favor the application of phonological phenomena throughout relatively long constituents. The subset-superset relationship inherent in current views of L2 acquisition, in particular the Asymmetry Hypothesis, predicts that reducing the domain of application of a process should be impossible to learn. In this light, we examine data (spontaneous and read speech of 11 Spanish speakers learning German) involving phonological processes which differ both in their segmental content and in their domains of application in the two languages. Our results are different from those predicted, that is, the pattern of acquisition cuts across the categories that would be established in such framework. Our findings thus demonstrate that the Asymmetry Hypothesis cannot be maintained as a model of L2 phonological acquisition, at least in its present form.
The Neurobiological Foundations of Giftedness

Case studies of extremely gifted individuals often reveal unique patterns of intellectual precocity and associated abnormalities in development and behavior. This article begins with a review of current neurophysiological and neuroanatomical findings related to the gifted population. The bulk of scientific inquiries provide evidence of unique patterns of right prefrontal cortex and inferior frontal activation implicated in gifted intelligence, although additional studies suggest enhanced neural processing and cerebral bilateralism. Geschwind, Behan, and Galaburda (GBG) first hypothesized the possible neurodevelopmental factors that account for unique brain development. This article explores more recent findings taken from the prenatal exposure literature and offers a proposed model for explaining aberrant developmental forces that may be at work in precocious individuals.
The pathogenesis of vasodilatory shock.

Profound vasoconstriction in the peripheral circulation is the normal response to conditions in which the arterial pressure is too low for adequate tissue perfusion, such as acute hemorrhagic or cardiogenic shock. In other conditions, the most frequent of which is septic shock,1,2 hypotension occurs as a result of failure of the vascular smooth muscle to constrict. Such so-called vasodilatory shock is characterized not only by hypotension due to peripheral vasodilatation but also by a poor response to therapy with vasopressor drugs. This syndrome has long attracted interest and defied understanding, but recent work on the function of vascular smooth .
Etiological profile of epilepsia partialis continua among adults in a tertiary care hospital.

BACKGROUND Epilepsia partialis continua (EPC), is a subtype of status epilepticus, have a varied spectrum of etiology and the out-come depends on the etiology. AIMS AND OBJECTIVES The present study is aimed to analyze the clinical characteristics and outcome. MATERIALS AND METHODS This is a prospective analysis of 17 patients admitted to our center between August 2010 and April 2012. EPC was defined as regular or irregular clonic muscular twitches affecting a limited part of the body, occurring for a minimum of 1 h, and recurring at intervals of no more than 10 s. The data collected included etiology, radiological findings, electroencephalogram (EEG) abnormalities, associated comorbid conditions, and outcome. RESULTS The mean age at presentation was 44.26 ± 13.77 years and the mean duration was 2.7 ± 1.5 days. There were ten patients with diabetic non-ketotic hyperosmolar state and one patient each of oligodendroglioma, varicella zoster vasculitis, central nervous demyelination, ischemic stroke, post traumatic seizure, arteriovenous malformation, and in one patient no cause could be established. Imaging showed abnormality only in five patients and EEG was abnormal in four patients. The EPC was controlled by one antiepileptic drug (AED) in eight patients, with two AEDs in seven patients and two patients required three AEDs. CONCLUSION EPC is a rare type of focal motor status epilepticus. Treatment of the underlying cause in addition to controlling EPC is essential to achieve the good outcomes.
Facial Expression Sequence Synthesis Based on Shape and Texture Fusion Model

Shape and texture are two aspects in facial expression synthesis. For the requirements of synthesized shape and texture are different, it is unsuitable to use same method to synthesize shape and texture. In this paper, we propose a Statistical Shape and Radio texture fusion model for facial expression sequence synthesis. In this framework, facial shape and texture had been processed separately, then they had been fused together to synthesize final result. The main contributes of this paper are: First propose statistical shape and radio texture fusion model, process shape and texture separately. Second introduce ASM model into facial shape synthesis, and construct expression model of ASM parameters. Third put forward a shape based sample select mechanism, fusion shape and texture process together. Experiment results demonstrate that the proposed model is more expressive and realistic than traditional methods, and can process batch input well.
A New Information Hiding Method Based on Improved BPCS Steganography

Bit-plane complexity segmentation (BPCS) steganography is advantageous in its capacity and imperceptibility. The important step of BPCS steganography is how to locate noisy regions in a cover image exactly. The regular method, black-and-white border complexity, is a simple and easy way, but it is not always useful, especially for periodical patterns. Run-length irregularity and border noisiness are introduced in this paper to work out this problem. Canonical Cray coding (CGC) is also used to replace pure binary coding (PBC), because CGC makes use of characteristic of human vision system. Conjugation operation is applied to convert simple blocks into complex ones. In order to contradict BPCS steganalysis, improved BPCS steganography algorithm adopted different bit-planes with different complexity. The higher the bit-plane is, the smaller the complexity is. It is proven that the improved BPCS steganography is superior to BPCS steganography by experiment.
SMAP: Simultaneous Mapping and Planning on Occupancy Grids

Occupancy grids are the most common framework when it comes to creating a map of the environment using a robot. This paper studies occupancy grids from the motion planning perspective and proposes a mapping method that provides richer data (map) for the purpose of planning and collision avoidance. Typically, in occupancy grid mapping, each cell contains a single number representing the probability of cell being occupied. This leads to conflicts in the map, and more importantly inconsistency between the map error and reported confidence values. Such inconsistencies pose challenges for the planner that relies on the generated map for planning motions. In this work, we store a richer data at each voxel including an accurate estimate of the variance of occupancy. We show that in addition to achieving maps that are often more accurate than tradition methods, the proposed filtering scheme demonstrates a much higher level of consistency between its error and its reported confidence. This allows the planner to reason about acquisition of the future sensory information. Such planning can lead to active perception maneuvers that while guiding the robot toward the goal aims at increasing the confidence in parts of the map that are relevant to accomplishing the task.
Axioms for uncertainty measures on belief functions and credal sets

In this paper we present a system of axioms for total uncertainty measures, which can be equivalently defined for belief functions and credal sets. This system of axioms provides that a measure of total uncertainty coincides with Shannon entropy on the set of probability measures and it is the Hartley measure on the set of {0,1}-valued belief measures. We check this system of axioms for the well-known candidates for total uncertainty measures; in particular, the upper entropy obeys all the necessary requirements. Some properties of such measures of total uncertainty allow us to propose ways for disaggregation of these measures into two parts, which correspond to measures of conflict and measures of nonspecificity.
Retrolental fibroplasia: I. Clinical observations.

• The changes occurring in retrolental fibroplasia were studied in 97 premature infants with fundus photography and fluorescein angiography. The macrovascular lesion of proliferative retrolental fibroplasia was identified as a functioning arteriovenous shunt. The microvascular abnormalities were capillary tufts, collaterals, capillary-free zones, and neovascular membranes. Regression was signaled by the ingrowth of capillaries from the shunt into the avascular retina. Cicatrization was characterized by persistence of the vascular abnormalities of the prollferative phase and organization of the avascular retina into a contracting scar.

Do Infants Show Distinct Negative Facial Expressions for Fear and Anger? Emotional Expression in 11-Month-Old European American, Chinese, and Japanese Infants

Abstract Do infants show distinct negative facial expressions for different negative emotions? To address this question, European American, Chinese, and Japanese 11-month-olds were videotaped during procedures designed to elicit mild anger or frustration and fear. Facial behavior was coded using Baby FACS, an anatomically based scoring system. Infants’ nonfacial behavior differed across procedures, suggesting that the target emotions were successfully elicited. However evidence for distinct emotion-specific facial configurations corresponding to fear versus anger was not obtained. Although facial responses were largely similar across cultures, some differences also were observed. Results are discussed in terms of functionalist and dynamical systems approaches to emotion and emotional expression.
Leisure Activity Patterns and Marital Satisfaction Over the Marital Career.

This paper investigates the relationship between the proportion of time husbands and wives spend in individual, joint, and parallel leisure activities and marital satisfaction over five marital career periods. A probability sample of upper-middle-class families in a moderate-sized Southeastern city yielded 216 husbands and 226 wives for the study. The results suggest that the three leisure activity patterns are differentially related to marital satisfaction, that husbands and wives are not influenced alike by leisure, and that the marital career period is a most critical variable in determining the influence of leisure.
Towards a professional sociology on China

This article identifies two internal tensions that Chinese sociology has constantly encountered since the discipline was reestablished in 1979: public versus professional and indigenization versus internationalization. I argue that professionalization is a necessary and crucial step to achieving unity in the study of social changes in contemporary China and to contributing to general knowledge in the discipline of sociology.
An Application of Multidimensional Time-Frequency Analysis as a Base for the Unified Watermarking Approach

A watermarking approach based on multidimensional time-frequency analysis is proposed. It represents a unified concept that can be used for different types of data such as audio, speech signals, images or video. Time-frequency analysis is employed for speech signals, while space/spatial-frequency analysis is used for images. Their combination is applied for video signals. Particularly, we focus on the 2-D case: space/spatial-frequency based image watermarking procedure that will be subsequently extended to video signal. A method that selects coefficients for watermarking by estimating the local frequency content is proposed. In order to provide watermark imperceptibility, the nonstationary filtering is used to model the watermark which corresponds to the host signal components. Furthermore, the watermark detection within the multidimensional time-frequency domain is proposed. The efficiency and robustness of the procedure in the presence of various attacks is proven experimentally.
