Clinical Outcome of Double Kissing Crush Versus Provisional Stenting of Coronary Artery Bifurcation Lesions

Background— Provisional stenting is effective for anatomic simple bifurcation lesions. Double kissing crush stenting reduces the 1-year rate of target lesion revascularization. This study aimed to investigate the 5-year clinical results of the DKCRUSH-II study (Randomized Study on Double Kissing Crush Technique Versus Provisional Stenting Technique for Coronary Artery Bifurcation Lesions). Methods and Results— A total of 370 patients with coronary bifurcation lesions who were randomly assigned to either the double kissing crush or provisional stenting group in the DKCRUSH-II study were followed for 5 years. The primary end point was the occurrence of a major adverse cardiac event at 5 years. Patients were classified by simple and complex bifurcation lesions according to the DEFINITION criteria (Definitions and Impact of Complex Bifurcation Lesions on Clinical Outcomes After Percutaneous Coronary Intervention Using Drug-Eluting Stents). At 5 years, the major adverse cardiac event rate (23.8%) in the provisional stenting group was insignificantly different to that of the double kissing group (15.7%; P=0.051). However, the difference in the target lesion revascularization rate between 2 groups was sustained through the 5-year follow-up (16.2% versus 8.6%; P=0.027). The definite and probable stent thrombosis rate was 2.7% in each group (P=1.0). Complex bifurcation was associated with a higher rate of target lesion revascularization (21.6%) at 5 years compared with 11.1% in patients with a simple bifurcation (P=0.037), with an extremely high rate in the provisional stenting group (36.8% versus 12.5%, P=0.005) mainly because of final kissing balloon inflation (19.4% versus 5.2%; P=0.036). Conclusions— The double kissing crush stenting technique for coronary bifurcation lesions is associated with a lower rate of target lesion revascularization. The optimal stenting approach based on the lesions’ complexity may improve the revascularization for patients with complex bifurcations. Clinical Trial Registration— URL: http://www.chictr. org.

FULL-RANGE NONLINEAR ANALYSIS OF FATIGUE BEHAVIOUR OF REINFORCED CONCRETE STRUCTURES BY FINITE ELEMENT METHOD

A new finite element analysis model is developed to analyze the stress and strain state of reinforced concrete structures including offshore concrete structures, subjected to any number of the cyclic load. Based on the analysis of the experimental data, this model simplifies the number of cycles - total cyclic strain curve of concrete as three straight line segments, and it is assumed that the stress - strain curves of different times of the cycles in each segment are the same, thus the elasto-plastic analysis is only needed for the first cycle of each segment, the stress or strain corresponding to any number of cycles can be obtained by superposition of stress or strain obtained by above elasto-plastic analysis based on the cyclic numbers in each segment.

Scalable Algorithms for Distribution Search

Distribution data naturally arise in countless domains, such as meteorology, biology, geology, industry and economics. However, relatively little attention has been paid to data mining for large distribution sets. Given n distributions of multiple categories and a query distribution Q, we want to find similar clouds (i.e., distributions), to discover patterns, rules and outlier clouds. For example, consider the numerical case of sales of items, where, for each item sold, we record the unit price and quantity; then, each customer is represented as a distribution of 2-d points (one for each item he/she bought). We want to find similar users, e.g., for market segmentation, anomaly/fraud detection. We propose to address this problem and present D-Search, which includes fast and effective algorithms for similarity search in large distribution datasets. Our main contributions are (1) approximate KL divergence, which can speed up cloud-similarity computations, (2) multi-step sequential scan, which efficiently prunes a significant number of search candidates and leads to a direct reduction in the search cost. We also introduce an extended version of D-Search: (3) time-series distribution mining, which finds similar subsequences in time-series distribution datasets. Extensive experiments on real multi-dimensional datasets show that our solution achieves up to 2,300 faster wall-clock time over the naive implementation while it does not sacrifice accuracy.
The basic helix–loop–helix domain of maize R links transcriptional regulation and histone modifications by recruitment of an EMSY-related factor

The control of anthocyanin accumulation in maize by the cooperation of the basic helix–loop–helix (bHLH) protein R with the MYB transcription factor C1 provides one of the best examples of plant combinatorial transcriptional control. Establishing the function of the bHLH domain of R has remained elusive, and so far no proteins that interact with this conserved domain have been identified. We show here that the bHLH domain of R is dispensable for the activation of transiently expressed genes yet is essential for the activation of the endogenous genes in their normal chromatin environment. The activation of A1, one of the anthocyanin biosynthetic genes, is associated with increased acetylation of histone 3 (H3) at K9/K14 in the promoter region to which the C1/R complex binds. We identified R-interacting factor 1 (RIF1) as a nuclear, AGENET domain-containing EMSY-like protein that specifically interacts with the bHLH region of R. Knockdown experiments show that RIF1 is necessary for the activation of the endogenous promoters but not of transiently expressed genes. ChIP experiments established that RIF1 is tethered to the regulatory region of the A1 promoter by the C1/R complex. Together, these findings describe a function for the bHLH domain of R in linking transcriptional regulation with chromatin functions by the recruitment of an EMSY-related factor.
Dermatitis caused by Ctenocephalides felis (cat flea) in human

Background: Human infestation to ectoparasites such as ticks, lice, cimex, fleas, mites and others agents may result in intensive allergic reaction with symptoms of itching, skin infection and severe irritation. In this case report, we present a case of dermatitis caused by cat flea. Case presentation: A three-member family referred to dermatology clinic in Babol due to dermal complications. They complained of irritation and the unrest caused by intense itching. Samples of tiny live insects were detected from their clothing which was recognized as C. felis (cat flea). Conclusion: This report highlights the importance of ectoparasites causing dermatitis.
Reducing the False Rejection Rate of Iris Recognition Using Textural and Topological Features

This paper presents a novel iris recognition system using 1D log polar Gabor wavelet and Euler numbers. 1D log polar Gabor wavelet is used to extract the textural features, and Euler numbers are used to extract topological features of the iris. The proposed decision strategy uses these features to authenticate an individual's identity while maintaining a low false rejection rate. The algorithm was tested on CASIA iris image database and found to perform better than existing approaches with an overall accuracy of 99.93%. MONG the present biometric traits, iris is found to be the most reliable and accurate (1). The use of human iris as a biometric feature offers many advantages over other biometric features. Iris is the internal human body organ that is visible from outside, but well protected from external modifiers. It has epigenetic formation and it is formed from the individual DNA, but a large part of its final pattern is developed at random. Two eyes from the same individual, although are very similar, contain unique patterns. Similarly, identical twins would exhibit four different iris patterns. These characteristics make it attractive for use as a biometric feature to identify individuals. Pattern recognition and image processing algorithms can be used to extract the unique patterns of iris from an eye image and encode it into an iris template. This iris template contains mathematical representation of the unique information stored in the iris and allows comparisons to be made between templates. Since 1990s, many researchers have worked on this problem. Human iris recognition process is basically divided into four steps, • Localization: Inner and outer boundaries of the iris are extracted.
Bus-Based and NoC Infrastructure Performance Emulation and Comparison

In this paper, we study and compare the performance of bus-based and Mesh-based with Spidernet NoC-based infrastructure in Altera’s FPGA. We first analysis the inner latency performance of the NoC infrastructure among routers, and we provide two modes to emulate the specific application on those infrastructures for the purpose of performance comparison. It is shown that NoC-based infrastructure performs better than bus-based one in terms of latency when the number of flits contained in the packets exceeds certain threshold. In addition, Spidernet-based infrastructure outperforms Mesh-based one under the same condition, which verifies the correctness of the theoretical performance analysis.
Two Extensions to Multi-label Correlation-Based Feature Selection: A Case Study in Bioinformatics

This paper proposes two extensions to a Multi-Label Correlation Based Feature Selection Method (ML-CFS): (1) ML-CFS using the absolute value of the correlation coefficient in the equation for evaluating a candidate feature subset, and (2) ML-CFS using Mutual Information for class label weighting. These extensions are evaluated in a bioinformatics case study addressing the multi-label classification of a cancer-related DNA micro array dataset with over 20,000 features. The results show that ML-CFS with absolute value of correlation obtained a significantly better predictive accuracy (smaller hamming loss) than the original ML-CFS. On the other hand, using Mutual Information to assign weights to labels showed some positive effect when using the ML-RBF classifier, but it showed a negative effect when using the ML-kNN classifier.
Correlates of Utilization of Skilled Maternal Health Services in Siaya County, Western Kenya

Background: Evidence suggests that antenatal care, skilled attendance at birth, postnatal care and continuum of care are key factors in reducing the risk of maternal death. However, in counties such as Siaya County, utilization of skilled maternal health services has remained low with high maternal morbidity and mortality from preventable conditions. Hence this study aimed to assess the correlates of utilization of skilled maternal health services in Siaya County in western Kenya. Methods: The study was carried out in Siaya County as a baseline for a longitudinal study which was involving a total of 517 pregnant women who had had previous maternal health utilization experience (those who had had previous delivery). The correlates were identified using binary and multivariate logistic regression. Results: Those who received at least one antenatal care visit were 84.9%, skilled delivery were 55.7% while only 23.6% received post-natal care within 48 hours of delivery. Of note was that only 53.2% received the WHO recommended ≥4 ANC visits. This study also revealed that those with no source of income (aOR=0.96, 95% CI: 3.21–8.27) and farmers (aOR=0.37, 95% CI: 7.32–6.74) were less likely to utilize maternal healthcare services relative to traders/self-employed and salaried. Women with secondary (aOR=2.62, 95% CI: 4.33–4.58) and tertiary (aOR=1.43, 95% CI: 2.87–4.63) education were more likely to utilize maternal healthcare services relative to those with no education and those with primary education. Similarly, women whose husbands had no education (aOR=0.89, 95% CI: 2.07–1.60) or had primary education (aOR=0.89, 95% CI: 2.07–1.60) were less likely to utilize maternal healthcare services relative to those whose husbands had secondary or tertiary level of education. Those who walked (0.91 (1.62-2.88) or used bicycle 0.84 (1.69-2.02) were less likely to utilize skilled maternal health services compared to those who used motorbike or private car. Despite intensified follow ups, only 53.2% utilized 4 antenatal care visits which could be an indication that there was pregnancy uncertainty. The study also revealed that some households (15.3%) had never been visited by a community health volunteer (CHV) which is an indication of disconnect in the continuum of care. Conclusion: Having no source of income, being a farmer, low education, husband/ partners education and walking or using a bicycle to hospital were significantly associated with low utilization of skilled maternal health services. There is need to avail pregnancy testing kits at the community for early diagnosis of pregnancy followed by early initiation of antenatal care services. A well designed performance evaluation system is important in ensuring that CHVs visit all the households assigned to them and that they deliver their tasks appropriately. Hence programs targeting increased utilization of skilled maternal health services needs to address these barriers.
Seroprevalence of H5 avian influenza virus in birds in the United Arab Emirates

VARIOUS serotypes of avian influenza (AI) virus have been isolated sporadically from birds in the United Arab Emirates (UAE), including H7N3, H7N1 and H9N2 ([Wernery and Manvell 2003][1], [Kent and others 2006][2]). Of these, only a H7N3 strain isolated from a peregrine falcon (Falco peregrinus) has
Bowel function and bother after treatment for early stage prostate cancer: a longitudinal quality of life analysis from CaPSURE.

PURPOSE We measured bowel function and bowel bother longitudinally the first 2 years after treatment for early stage prostate cancer. MATERIALS AND METHODS We studied bowel function and bother in 1,584 men recently diagnosed with early stage prostate cancer and followed for 2 years after radical prostatectomy, external beam radiation or brachytherapy. Principal outcomes were assessed with the UCLA Prostate Cancer Index, a validated instrument that includes these 2 domains. Multivariate analyses were conducted to ascertain significant predictors of bowel function and bother. Subjects were drawn from Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE, TAP Pharmaceutical Products, Inc., Lake Forest, Illinois), a national, longitudinal registry of men with prostate cancer. RESULTS Men treated with external beam radiation or brachytherapy suffered worse bowel function and were more bothered by it than men treated surgically. After an initial period of posttreatment impairment, all 3 groups demonstrated improvement with time in both domains, although bowel bother persisted longer in men treated with external beam radiation. Surgery patients reached a steady state by 3 months, while those treated with external beam radiation or brachytherapy continued to improve for more than a year after treatment. Older men were more bothered by bowel dysfunction than younger men. Ethnicity, comorbidity and education did not affect either bowel function or bother. CONCLUSIONS Patients undergoing surgery, external beam radiation or brachytherapy have different longitudinal profiles of bowel function and bother during the first 2 years after treatment. Bowel function and bother are worse after external beam radiation but they are also impaired after brachytherapy. Men choosing surgery experience transient impairment in the bowel domains. This information may be useful to patients making treatment decisions for early stage prostate cancer.
Behavior Chaining - Incremental Behavior Integration for Evolutionary Robotics

One of the open problems in autonomous robotics is how to consistently and scalably integrate new behaviors into a robot with an existing behavioral repertoire. In this work a new technique called behavior chaining is introduced, which allows for gradually expanding the behavioral repertoire of a dynamically behaving robot. The approach relies heavily on sca! olding: gradually restructuring the robot’s environment such that selection pressure favors the incorporation of a new behavior. This method teaches a robot a compound behavior not yet reported in the literature: dynamic legged locomotion toward an object followed by grasping, lifting and holding of that object in a physically-realistic three-dimensional environment. The method assumes that success is dependent on the order in which behaviors are learned. This is justified by results which show that if a robot is forced to learn lifting first and then incorporate locomotion, it eventually succeeds at both more often than a robot forced to learn locomotion first and then lifting.
Overview and status of metal S/D Schottky-barrier MOSFET technology

In this paper, the metal source/drain (S/D) Schottky-barrier (SB) MOSFET technology is reviewed. The technology offers several benefits that enable scaling to sub-30-nm gate lengths including extremely low parasitic S/D resistance (1% of the total device resistance), atomically abrupt junctions that enable the physical scaling of the device to sub-10-nm gate lengths, superior control of OFF-state leakage current due to the intrinsic Schottky potential barrier, and elimination of parasitic bipolar action. These and other benefits accrue using a low-thermal-budget CMOS manufacturing process requiring two fewer masks than conventional bulk CMOS. The SB-CMOS manufacturing process enables integration of critical new materials such as high-k gate insulators and strained silicon substrates. SB MOSFET technology state of the art is also reviewed, and shown to be focused on barrier-height-lowering techniques that use interfacial layers between the metal S/Ds and the channel region. SB-PMOS devices tend to have superior performance compared to NMOS, but NMOS performance has recently improved by using ytterbium silicide or by using hybrid structures that incorporate interfacial layers to lower the SB height.
A method for object detection based on pixel intensity comparisons

We describe a method for visual object detection based on an ensemble of optimized decision trees organized in a cascade of rejectors. The trees use pixel intensity comparisons in their internal nodes and this makes them able to process image regions very fast. Experimental analysis is provided through a face detection problem. The obtained results are encouraging and demonstrate that the method has practical value. Additionally, we analyse its sensitivity to noise and show how to perform fast rotation invariant object detection.
Intravascular catheter-related infections in an Indian tertiary care hospital.

INTRODUCTION This study had two objectives: 1) to determine the clinical and microbiological profiles of patients developing intravascular catheter-related local (localized catheter colonization and exit site) and systemic infections and their predisposing factors; 2) to study the antibiotic sensitivity patterns of the organisms isolated. METHODOLOGY This case-control study was conducted over 19 months involving 232 patients at a tertiary care hospital. Non-tunneled central venous catheters and midline catheters were the two types studied. Catheter tips were processed using Maki's roll plate and endoluminal flush techniques. Blood cultures were drawn under strict aseptic precautions and processed by the BacT ALERT system. A "case" was any patient with proven localized catheter colonization, exit site infection or blood-stream infection and a "control" was any patient from whom the intravascular catheter yielded no organism in semi-quantitative cultures. RESULTS AND CONCLUSIONS The incidence of catheter-related blood-stream infections (CRBSI) in our institute was 8.75 per 1,000 catheter days. The commonest organisms causing local infections were coagulase-negative Staphylococci, and those causing CRBSI were Staphylococcus aureus. Multidrug-resistant organisms accounted for 30.2% of the infections. Risk factors for development of catheter-related infections included an immune compromised state, duration of the catheter in situ, femoral venous cannulation, and triple lumen catheters. Choice of venous cannulation to minimize the risk of catheter-related infection in ascending order for risk of infection is the subclavian vein, jugular vein, basilic vein and then the femoral vein. There was no role for empirical antibiotic therapy to prevent intravascular catheter-related local or systemic infections.
Learning Times for Large Lexicons Through Cross-Situational Learning

Cross-situational learning is a mechanism for learning the meaning of words across multiple exposures, despite exposure-by-exposure uncertainty as to a word's true meaning. Doubts have been expressed regarding the plausibility of cross-situational learning as a mechanism for learning human-scale lexicons in reasonable timescales under the levels of referential uncertainty likely to confront real word learners. We demonstrate mathematically that cross-situational learning facilitates the acquisition of large vocabularies despite significant levels of referential uncertainty at each exposure, and we provide estimates of lexicon learning times for several cross-situational learning strategies. This model suggests that cross-situational word learning cannot be ruled out on the basis that it predicts unreasonably long lexicon learning times. More generally, these results indicate that there is no necessary link between the ability to learn individual words rapidly and the capacity to acquire a large lexicon.
Evolution of the Social Brain

Why are monkeys, apes and humans such social animals and how did we get that way? As [Dunbar][1] describes in his Perspective, such questions have puzzled primatologists for decades. Two new studies in baboons provide some answers by demonstrating that the tighter the social bonds of female baboons the greater is their reproductive fitness ([ Silk et al .][2]), and that female baboons are able to simultaneously assess the rank and kinship of other baboon females ([ Bergman et al ][3].).
