Elusive anomalies

چکیده
Abstract Usually, in order to compute an anomaly (be it chiral or trace) with a perturbative method, the lowest significant is sufficient. With help of gauge diffeomorphism invariance uniquely identifies anomaly. This note short review ambiguities that arise calculation trace anomalies, and meant, particular, signal cases which not enough unambiguously identify may shed light on some recent contradictory results.

The elusive Effect of Routing Dynamics on Traffic Anomalies
Network operators need to know the root cause of traffic anomalies to determine the appropriate action to mitigate their effect. This paper studies the one type of anomaly for which we can know the root cause: routing-induced anomalies. A major challenge in quantifying the effect of routing events on traffic is that the flows affected by routing are not easily distinguishable from the rest of t...

متن کاملElusive Visualizations
Visual media permeates and increasingly dominates Western culture. In nearly every area of our lives, at work and leisure, in everything from movies and computer operating systems to television programs and magazine ads, we are bombarded with images and symbols. Even the imaging methods common in modern medical practice, the sonogram, MRI, and CAT scan, are familiar to us independent of direct ...
متن کاملReplication Unreliability in Psychology: Elusive Phenomena or “Elusive” Statistical Power?
The focus of this paper is to analyze whether the unreliability of results related to certain controversial psychological phenomena may be a consequence of their low statistical power. Applying the Null Hypothesis Statistical Testing (NHST), still the widest used statistical approach, unreliability derives from the failure to refute the null hypothesis, in particular when exact or quasi-exact r...
