Authors: Lai Jennifer Yi‐Chun , Atzmon Gil , Melamed Michal L. , Hostetter Thomas H. , Crandall Jill P. , Barzilai Nir , Bitzer Markus
Published: March 2012

Objectives

To test whether lower serum uric acid (UA) levels are associated with longevity independent of renal function.

Design

Cross‐sectional cohort study.

Setting

Ashkenazi Jewish individuals with exceptional longevity (Longevity Genes Project at Albert Einstein College of Medicine).

Participants

Long‐lived individuals (LLI) of Ashkenazi Jewish ethnicity (mean age ± standard deviation 97.7 ± 2.9, n = 365), their offspring (mean age  ± standard deviation 68.2 ± 8.2, n = 593) and controls (without family history of longevity, mean age ± standard deviation 72.5 ± 9.9, n = 356).

Measurements

Association between UA levels and estimated glomerular filtration rate (eGFR) as well as chronic kidney disease (CKD) stage, and correlation of UA levels of LLI and offspring were determined. Because LLI lack an appropriate control group, UA levels, eGFR, and prevalence of hyperuricemia and CKD stages were compared between offspring and controls.

Results

Offspring were less likely to have hyperuricemia and had lower UA levels than controls. Despite negative correlation between UA levels and eGFR and positive correlation between UA levels and CKD stages, eGFR and the prevalence of CKD stage III to V were not found to be different between offspring and controls. Furthermore, significant association between UA levels in LLI and their offspring (β estimate 0.1544, 95% confidence interval = 0.08–0.23, P < .001) has been observed.

Conclusion

Offspring had lower UA levels than controls despite similar renal function, suggesting that other factors such as UA metabolism or renal tubular transport determine UA levels. The association between UA levels and longevity is particularly intriguing because UA levels are potentially modifiable with diet and drugs.

Authors: Ghashghaie Sasan , Marzbanrad Ehsan , Raissi Babak , Zamani Cyrus , Riahifar Reza
Published: March 2012

In present study, the effect of low frequency electric field parameters on pearl chain formation (PCF) behavior of ZnO nanoparticles was investigated using co‐planar electrodes. The optical microscopy images of the deposition patterns obtained at the frequency range of 1 Hz–10 kHz revealed that below 10 kHz, Coulomb force, unsteady‐state fluid flow and Alternating‐electro‐osmotic phenomenon dominate the deposition process preventing directional assembly of particles into chains. However, at 10 kHz the ZnO nanoparticles were observed to form chainlike patterns along the electric field lines bridging the interelectrode gap which was attributed to the dielectrophoresis force. The optimized PCF conditions were then employed to fabricate a CO gas sensor which showed a clear response to the target gas at 400°C, 450°C and 500°C. The porous layer obtained at 10 kHz also showed higher response to 3–17 ppm of NO2 at 250°C–500°C which was attributed to easier gas flow through the layer and more reaction area compared with the dense film made using the sedimentation technique.
High‐Level Methodologies to Evaluate Naval Task Groups
Authors: MARTENS RANDY , REMPEL MARK
Published: March 2012

Defense organizations within many nations (e.g., United States and Canada), use capability‐based planning (CBP) to guide their force development processes. A key element of the CBP process is testing current and proposed capabilities against force planning scenarios, particularly for asset evaluation. This analysis involves a wide range of capabilities, and thus is a multicriteria problem. Comparison of alternatives using multiple criteria is challenging, and often is assisted by aggregation techniques. Set in a naval context, this paper presents three high‐level capability aggregation techniques: the vector method, star plot method, and wedge method. Each method aggregates naval task group capabilities, with respect to a scenario, into three quantifiable measures: effectiveness, unmatched, and unused. As with numerous techniques, the effectiveness gauges the ability of a task group to meet a set of scenario requirements. The unmatched and unused measures yield insight into capability gaps, which is an important aspect of CBP. The unmatched metric measures scenario requirements that are not provided by a task group and the unused metric measures task group capabilities that are not required by a scenario. An application of the methods is presented, including a discussion of their strengths and weaknesses. Based on this work, it is concluded that the vector method is the best of the three presented.
Contingent absences account for range limits but not the local abundance structure of an invasive springtail
Authors: Treasure Anne M. , Chown Steven L.
Published: March 2012

Understanding spatial variation in abundance is essential for forecasts of responses to environmental change impacts on diversity and the consequent conservation actions. However, few studies have sought to distinguish the causal basis of abundance structure and range limits. Here we do so for an invasive springtail species,Pogonognathellus flavescens, in a cold temperate island setting. Local microclimate variables and physiological tolerances of this habitat generalist suggest that it should be widely distributed across a range of habitats below 200 m elevation on the island. By contrast, island‐wide and local abundance surveys show that it is restricted to indigenousPoa cookiitussock grassland habitats in the southeast. Preference for this habitat is correlated with the presence of vertebrates and a threshold response to soil Ca and pH, with preference for low values of both. Habitat specificity may be the consequence of a founder effect because the species is characterized by only a single mitochondrial COI haplotype. Nonetheless,P. flavescensis absent from many other areas of suitableP. cookiihabitat around the island. The most plausible explanation appears to be dispersal limitation (i.e. a contingent absence). Despite high locomotion speeds measured in the laboratory at optimum and mean annual soil temperatures (0.97 and 0.42 cm s−1at 26°C and 6.5°C, respectively), dispersal in the field indicated that >100 yr would be required to reach all available habitat in the absence of jump dispersal, for which few vectors exist. Thus, current range limits are set by dispersal limitation (i.e. contingent absences) whilst abundance structure is a function of variation in soil substrate quality. Edaphic variables both in this species and other soil invertebrates may be more significant than climatic factors in determining abundance and occurrence, indicating that they should be routinely included in species distribution models. Low genetic diversity and high habitat preference suggest that in the absence of introduction of additional individuals, the species will not spread rapidly at the island. However, over time, the widening distribution of its preferred habitat,P. cookii, as a consequence of a major management intervention (the eradication of feral cats), may enable it to colonize all suitable areas.
Biologics in oral medicine: principles of use and practical considerations
Authors: O’Neill ID , Scully C
Published: March 2012

Oral Diseases (2012) 18, 525–536

Biologic therapies are relatively innovative treatments aimed at modulating lymphocytes or cytokines. There are currently three broad classes of biologic therapies, tumour necrosis factor‐alpha inhibitors, lymphocyte modulators and interleukin inhibitors; all are increasingly used in the treatment of inflammatory immune‐mediated conditions, and several have potential applications in oral medicine. Guidelines for their use in licensed indications (e.g. rheumatoid arthritis, psoriasis, inflammatory bowel disease) include recommendations and guidance for patient selection and subsequent monitoring with discussion of potential adverse effects. An understanding of these is important when managing patients receiving biologic therapy for systemic disease, and compliance is essential in any use in oral medicine. Key aspects of current guidance are presented with particular emphasis on their relevance to clinicians working within oral and maxillofacial medicine/pathology/surgery and in specialist practice.

A Case-Control Analysis on the Association Between Erectile Dysfunction and Sudden Sensorineural Hearing Loss in Taiwan
Authors: Keller Joseph J. , Chen Yi-Kuang , Lin Herng-Ching
Published: March 2012

Introduction

Although the cause of sudden sensorineural hearing loss (SSNHL) is yet to be elucidated, many theories have been proposed regarding potentially contributory etiologies. One increasingly well-supported theory purports an underlying vascular pathomechanism. If this is the case, SSNHL may also associate with conditions comorbid with vascular diseases, such as erectile dysfunction (ED). However, no studies to date have investigated the association between ED and SSNHL.

Aim

This study set out to estimate a putative association between ED and having been previously diagnosed with SSNHL using a population-based dataset with a case-control design.

Methods

This study used administrative claim data from the Taiwan National Health Insurance program. We identified 4,504 patients with ED as the study group and randomly selected 22,520 patients as the comparison group. Conditional logistic regression was used to examine the association between ED and having previously received a diagnosis of SSNHL.

Main Outcome Measure

The prevalence and risk of SSNHL between cases and controls were calculated.

Results

Of the sampled patients, 41 (0.15%) had been diagnosed with SSNHL before the index date; 22 (0.49% of the cases) were from the study group and 19 (0.08% of controls) were from the control group. Conditional logistic regression analysis revealed that after adjusting for the patient’s monthly income, geographic location, hypertension, diabetes, hyperlipidemia, coronary heart disease, obesity, and alcohol abuse/alcohol dependence syndrome status, patients with ED were more likely than controls to have been diagnosed with SSNHL before the index date (odds ratio = 6.06, 95% confidence interval = 3.25–11.29).

Conclusions

There was an association between ED and prior SSNHL. The results of this study add to the evidence supporting an underlying vascular pathomechanism regarding the development of SSNHL and highlight a need for clinicians dealing with SSNHL patients to be alert to the development of ED.
Young Women’s Perceived Health and Lifetime Sexual Experience: Results from the National Survey of Family Growth
Authors: Hall Kelli S. , Moreau Caroline , Trussell James
Published: March 2012

Introduction

Sexuality is a component of health and well-being for all women, including adolescents. Yet relationships between young women’s health perceptions and sexual behavior are unclear.

Aim

We examined associations between perceived health and lifetime sexual experiences among young U.S. women.

Methods

We used data from 4,413 young women ages 15–24 years in the National Survey of Family Growth, 2002–2008. Descriptive, bivariate, and multivariate statistics estimated relationships between categories of perceived health and types of lifetime sexual experience.

Main Outcome Measures

A self-rated health Likert item and sexual history questions were administered with a computer-assisted survey instrument.

Results

Young women reported excellent (30%), very good (41%), good (23%), and fair-poor (6%) health. Sexual experiences included vaginal (64%), oral (64%), and anal (20%) sex. Negative experiences included involuntary sex (11%) and sexually transmitted infection (STI) history (8%). In multivariate logistic regression models, lower perceived health (“good” rather than “excellent”) was positively associated with vaginal (odds ratio [OR] 1.5, confidence interval [CI] 1.1–2.1, P = 0.02), oral (OR 1.5, CI 1.1–2.1, P = 0.005), and anal (OR 1.4, CI 1.0–2.0, P = 0.03) sex. In models stratified by age, point estimates for vaginal (OR 1.8, CI 1.2–2.6, P = 0.002) and oral (OR 1.9, CI 1.4–2.6, P < 0.001) sex were higher among adolescents ages 15–19 years, but associations were insignificant among young adults ages 20–24 years. When controlling for negative sexual experiences, point estimates were stable in models including STI history but statistically insignificant when including involuntary sexual experience. Other characteristics associated with sexual experiences varied by type of experience and included age, race/ethnicity, employment situation, poverty level, insurance status, childhood family situation, religious service participation, cohabitation/marital experience, and body mass index.

Conclusions

Further investigation is warranted to disentangle potentially negative relationships between perceived health (as well as response bias and more objective health outcomes), sociodemographic factors, and diverse sexual experiences among young women in the United States.

Color consilience: color through the lens of art practice, history, philosophy, and neuroscience
Authors: Conway Bevil R.
Published: March 2012

Paintings can be interpreted as the product of the complex neural machinery that translates physical light signals into behavior, experience, and emotion. The brain mechanisms responsible for vision and perception have been sculpted during evolution and further modified by cultural exposure and development. By closely examining artists’ paintings and practices, we can discover hints to how the brain works, and achieve insight into the discoveries and inventions of artists and their impact on culture. Here, I focus on an integral aspect of color, color contrast, which poses a challenge for artists: a mark situated on an otherwise blank canvas will appear a different color in the context of the finished painting. How do artists account for this change in color during the production of a painting? In the broader context of neural and philosophical considerations of color, I discuss the practices of three modern masters, Henri Matisse, Paul Cézanne, and Claude Monet, and suggest that the strategies they developed not only capitalized on the neural mechanisms of color, but also influenced the trajectory of western art history.

This pooled analysis of ambulatory blood pressure (BP) monitoring data from two 8‐week randomized controlled trials compared the antihypertensive efficacy and safety of combination aliskiren/valsartan vs valsartan alone in hypertensive patients (nocturnal dippers or nondippers). At study end, patients were taking aliskiren/valsartan 300/320 mg or valsartan 320 mg. In dippers (n=138) and nondippers (n=132), aliskiren/valsartan provided significantly (P<.05) greater reductions from baseline to week 8 than valsartan in 24‐hour, daytime, and last‐4‐hour mean ambulatory systolic BP (maSBP). Treatment differences were more pronounced in nondippers. Nighttime maSBP reductions with aliskiren/valsartan were significantly greater vs valsartan in nondippers (−17.0 mm Hg vs −8.9 mm Hg; P<.05) but not dippers (−7.6 mm Hg vs −4.5 mm Hg; P=.16). In all time periods, combination therapy was generally associated with BP reductions that were greater in nondippers than dippers. Conversion from nondipper to dipper status was 32% vs 22% for aliskiren/valsartan vs valsartan (P=.48). Both treatments were similarly well tolerated. Although the addition of aliskiren to valsartan did not significantly alter dipper status, our data suggest an increased contribution of the renin‐angiotensin‐aldosterone system to the nondipper status of hypertensive patients.

Published: March 2012

Considering the importance of careful segmentation of medical images for deleanition of unhelthy tissues or locating and tracing of the tumor growth, it has been the subject of interest in many medical researches. In this paper we propose a gossip-based region growing algorithm to extract more accurate spatial features. The features will then be imported to a random forest. The random forest classifier is an ensemble classifier derived from the decision tree idea but with accuracy rates comparable to most of currently used classifiers. Although being a very strong classifier, random forest has rarely been studied in the field of medical segmentation. The brain scans segmentation with random forest showed promising results using the gossip-based region growing algorithm.

The idea of this essay is to indicate; geographical data systems is graphically which includes, spatial data, non-spatial data and neighborhood connection among them, then we can use spatial outliers to derive Landmarks from graphs.
3D Object Reflection Rendering Based on Non-Uniform Sampling
Authors: Wang Lili , Zhang Erlin , Chen Yi , Ma Zhiqiang
Published: March 2012

Traditional reflection rendering methods have uniform sampling rate over the reflective objects, which cannot provide the surface information sufficiently when data importance and complexity of the surface is non-uniform. Besides, observing the objects, people have one or more visual focus areas. Considering these reasons, rendering reflection requires to highlight corresponding parts. In this paper, a new method for rendering the reflection of 3D objects is proposed, which is based on non-uniform sampling. Our method makes up the shortage of traditional reflection rendering. In the previous phase of rendering, we need to get the sampling map of reflected object image; then according to the sampling map we could gain the distort image of reflected object; finally, render the reflection with the help of reconstruct non-uniform image. Further, we explore the way of generating sampling map automatically. Therefore, it can render 3D object reflection in real time. The work of this paper enables less computation but better effect of rendering reflection in scenarios, using non-uniform image with totally lower resolution.

Published: March 2012

Accelerated advancement in the field of System-on-Chip necessitates solving the bus contention in a most efficient manner. In any real time computing system, the major challenge is to reduce the latency of the system and to achieve a fair bandwidth allocation. Implanting processors according to their traffic behavior on to the Adaptive Arbitration architecture can be one of the feasible options to tackle the aforesaid problems to a remarkable extent. This combination of Adaptive Arbitration and the processors according to their traffic behavior has interesting advantages compared with other conventional arbiters due to its fair bandwidth allotment and low system latency. This article provides a comprehensive picture of the global scenario of Adaptive Arbitration algorithm for fair bandwidth allocation so as to enable researchers to decide the direction of further investigation. Some of the works published so far in this area are reviewed, classified according to their objectives and presented in an organized manner with a final conclusion.

Four Features Contourlet Texture Retrieval
Authors: Guo Zhen , Chen Xin-Wu
Published: March 2012

Contourlet transform is a non-tensor product special transform and has better performance in directional information representation than wavelet and superior to wavelet at retrieval application fields. In order to improve the retrieval rate further, we will propose a new contourlet transform based texture image retrieval system in this paper. In the system, standard deviation, energy, skewness and kurtosis of each subband coefficients in contourlet domain are cascaded to form feature vectors, and the similarity metric is Canberra distance. Experimental on a 109 texture image database from MIT results show that this contourlet transform based image retrieval system is superior to that of the contourlet transform with energy and standard deviations features widely used today under the same system structure.

Dataflow-Based Type Recovery Algorithm for Binary Code
Authors: Hu Yan , Jiang He
Published: March 2012

Data type recovery is required for in-depth analysis of binary code. In this paper, a constraint-based type recovery algorithm(CBTR) was studied first. The CBTR algorithm does not make use of control flow information in the type recovery process. To make up for CBTR's deficiency, an enhanced data flow based type recovery algorithm(DBTR) is proposed. DBTR builds control flow graph and data flow graph upon the disassembly of binary code. Empirical study shows that with dataflow information, DBTR is superior to CBTR in the precision of type recovery.
Information Extraction of Coastal Landscape and its Response to Dam Disturbance in Yellow River Delta Based on Remote Sensing Images
Authors: Fu Xin , Liu Gaohuan
Published: March 2012

In this paper, the landscape cover, the coastline and artificial dams were extracted from Landsat 5 TM and SPOT5 images by the combination of supervised classification based on Support Vector Machine (SVM) and visual interpretation. And the influence of artificial dams on landscape structure and landscape pattern was analyzed by landscape pattern index and gradient analysis of NDVI. The results suggest that, the accuracy of landscape cover extraction met the requirements of change analysis of the landscape pattern. The artificial dams effectively prevented the backward erosion of inland area. In addition to the estuary area, the area of the tidal flat landscape was reduced a lot in the region without dams. Spatial and temporal analysis of landscape pattern indices showed that dam disturbance made the landscape structure changed largely and the degree of landscape fragmentation increased significantly. The change rates of mean area of patches (AREA_MN) and splitting index (SPLIT) were 1Â’0.79 and 6.98, respectively, which were higher than that of the region without dams. The trend of the gradient changes of NDVI in the region with dams on the distance from the coastline was nonlinear, while linear in the region without dams.

Published: March 2012

One of the major expenses about creating and developing a software, is the testing expenses; of which, one of the most important methods is the Mutation Testing. In this method, several versions of the original program including various errors are created and using the appropriate test samples, it's tried to discover the mistaken versions. The more proper the program and samples, the more number of mistaken versions will be discovered. In order to simulate this method, we need to design a system that executes the test data samples on many mistaken version and then through comparing these results with the main program, discover the versions with error. This method naturally has high calculative and operational costs. The cost includes, repetitive execution of each test data, creating versions with errors and modification of the test samples and mistaken versions if necessary. There're general methods to reduce the costs. The first category includes the methods which rely on performance expense reduction or reduction of the number of mistaken version. The second rely on fast and cheap data samples of the test that leads to reduction of comparisons between the output of the main program and mistaken versions. In this article, we're to make a comparison between the methods and introduce the system of mutation tests in order to improve the test data according to evolutionary algorithms.

Published: March 2012

A functional analytic method was developed by E.K.Ifantis in 1987 to prove that certain non-linear ordinary differential equations (ODEs) have a unique power series solution. We first introduced the resistant virus during single-drug therapy model of HIV infection. Then, we extended the functional analytic method to certain systems of two non-linear ordinary differential equations and applied the result to the HIV infection model governed by a system of two non-linear ordinary differential equations and obtained the power series solutions.

On the basis of the SIQR epidemic model which completely determines the global dynamics and results of disease was given in [1], considering the latency of the disease and introducing discrete time-delay, we established the new dynamic model with time delays describing epidemic. The basic reproduction number R0 which completely determines the global dynamics and results of disease was solved in this paper. We give a qualitative analysis of this model and reveal the inherent rule of infectious diseases.
Measuring Graph Similarity Using Node Indexing and Message Passing
Authors: Shen Gang , Li Wei
Published: March 2012

In this paper, we present a generative model to measure graph similarity. The parameters of that random process generating the observed graph from a template are determined by the node indices, reflecting the structure compatibility between nodes. We propose to use the steady state of the dynamic system represented by a directed graph to index the nodes. A message passing algorithm using the loopy belief propagation is adopted to approximate the maximum a posteriori assignment (MAP) for the nodes. The resulted believes of self matching form a similarity measure of the nodes in a graph. Examples and experiments demonstrated that the proposed method worked well for large graphs.
