Anomaly detection in IP networks, detection of deviations from what is considered normal, is an important complement to misuse detection based on known attack descriptions. Performing anomaly detection in real-time places hard requirements on the algorithms used. First, to deal with the massive data volumes one needs to have efficient data structures and indexing mechanisms. Secondly, the dynam...

Axial anomaly of lattice abelian gauge theory in hyper-cubic regular lattice in arbitrary even dimensions is investigated by applying the method of exterior differential calculus. The topological invariance, gauge invariance and locality of the axial anomaly determine the explicit form of the topological part. The anomaly is obtained up to a multiplicative constant for finite lattice spacing an...

Within the context of climate change, it is of utmost importance to quantify the stability of ecosystems with respect to climate anomalies. It is well acknowledged that ecosystem stability may change over time. As these temporal stability changes may provide a warning for increased vulnerability of the system, this study provides a methodology to quantify and assess these temporal changes in ve...

We examine the equivalence between the Konishi anomaly equations and the matrix model loop equations in N = 1 gauge theories, the mass deformation of N = 4 supersymmetric Yang-Mills. We perform the superfunctional integral of two adjoint chiral superfields to obtain an effective N = 1 theory of the third adjoint chiral superfield. By choosing an appropriate holomorphic variation, the Konishi an...

This research explores the relationship between El Niño/Southern Oscillation (ENSO), captured by equatorial PaciŽ c Ocean Sea Surface Temperature (SST), and interannual variation in vegetation vigour in the southeast USA, captured by Advanced Very High Resolution Radiometer (AVHRR) Normalized DiVerence Vegetation Index (NDVI), for the period 1982–1992. The moving average and ‘baseline’ methods ...

Previous work has shown that the N400 ERP component is elicited by all words, whether presented in isolation or in structured contexts, and that its amplitude is modulated by semantic association and contextual predictability. Although these data suggest that the N400 reflects core semantic computations involved in processing any meaningful stimulus, the broader literature continues to maintain...

regardless of severity, earlier intervention to correct hearing loss in children improves speech development and conversational abilities. a cross-sectional study was performed on 230 neonates who were at risk of hearing loss in tehran university of medical sciences hospitals between september 2000 and february 2002. hearing was examined before the 3rd month by auditory brainstem responses (abr...

background: stillbirth is a sensitive indicator for health care quality, living conditions and equity in a society. the aim of this study was to determine the rate and contributing factors of stillbirth at babol hospitals. methods: this cross-sectional, descriptive, analytical study was designed as an applied research, using census sampling in 2012-2013. a questionnaire was applied for data col...

in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...
