BACKGROUND Ebstein's anomaly is the most commonly occurring congenital abnormality associated with the Wolff-Parkinson-White (WPW) syndrome. However, the effects of Ebstein's anomaly on the risks and benefits of surgical ablation of accessory pathways in patients with WPW syndrome are unknown. METHODS AND RESULTS This study compared the long-term outcome of 38 WPW patients with Ebstein's anom...

Performance problems, which may stem from different system components, such as network, memory, and storage devices, are difficult to diagnose and isolate in distributed storage systems. In this paper, we present a performance anomaly detector which is able to efficiently detect performance anomaly and accurately identify the faulty sources in a system node of a distributed storage system. Our ...

The Internet can be made more secure and efficient with effective anomaly detection. In this paper, we describe a visual method for anomaly detection using archived Border Gateway Protocol (BGP) data. A special encoding of IP addresses built into an interactive visual interface design allows a user to quickly detect Origin AS changes by browsing through 2D visual representation of selected aspe...

In the class of streaming anomaly detection algorithms for univariate time series, the size of the sliding window over which various statistics are calculated is an important parameter. To address the anomalous variation in the scale of the pseudo-periodicity of time series, we define a streaming multi-scale anomaly score with a streaming PCA over a multi-scale lag-matrix. We define three metho...

using global free air gravity and topography data, first we have calculated a bouguer anomaly (ba) map for iranian plateau and then computed the residual isostasy anomaly map under the airy-heiskannen assumption. the term residual is used as to reflect the assumption of local isostatic compensation in contrast to a regional isostatic compensation. the value with which the gravity effect of the ...

We present a simple derivation of the one-loop trace anomaly in spinor QED through dispersion relations, avoiding completely any ultraviolet regu-larization. The anomaly can be expressed as a convergent sum rule for the imaginary part of a relevant formfactor. In the massless limit, the imaginary part produces a delta-function singularity at zero external momentum squared. Such a treatment reve...

Ebstein's anomaly is a rare entity affecting around 1 in 200,000 live births and accounts for less than 1% of congenital heart diseases. Ebstein's anomaly with an associated right-sided myxoma is extremely rare, with only one other case report found in the literature. Previous reports have also noted cases of Ebstein's anomaly associated with left-sided myxomas. We describe a female patient wit...

Bilateral femoral agenesis is a rare anomaly.  To the best of our knowledge, only three cases of simple congenital anomaly and three cases associated with femoral facial syndrome have been reported.  Here, we describe a simple form of bilateral femoral agenesis observed in one of the 2 dead fetuses delivered after termination of a 24-week twin pregnancy of a normal mother.  Post-mortem x-ray ex...

Our model shows that the discovery of an anomaly reduces its magnitude, regardless of whether the anomaly is due to risk or mispricing. After the discovery, the return from the anomaly becomes more correlated with the returns from other existing anomalies. While riskand mispricing-based anomalies have similar implications for asset prices, they have sharply different implications on investors’ ...
