Neuronal oscillations in cortical networks.
, 2004
"... Clocks tick, bridges and skyscrapers vibrate, neuronal networks oscillate. Are neuronal oscillations an inevitable by-product, similar to bridge vibrations, or an essential part of the brain's design? Mammalian cortical neurons form behavior-dependent oscillating networks of various sizes, whi ..."

, mechanisms that cooperatively support temporal representation and long-term consolidation of information. T he first human electroencephalographic (EEG) pattern described was an 8 to 12 Hz rhythm, the alpha waves of Berger (1), followed by a barrage of intensive clinical and basic research. From scalp
Activation of the middle fusiform ‘face area’ increases with expertise in recognizing novel objects,

more involved in face than object processing by subtracting the activation when subjects passively viewed non-face common objects from that obtained when viewing faces (localizer task 6 ). This led to the selection of two 8 ´8 voxel (each voxel, 1.3 ´1.7 mm; see Methods) regions of interest (ROIs
Chaos in neuronal networks with balanced excitatory and inhibitory activity
, 1996
"... Neurons in the cortex of behaving animals show temporally irregular spiking patterns. The origin of this irregularity and its implications for neural processing are unknown. The hypothesis that the temporal variability in the firing of a neuron results from an approximate balance between its excitat ..."

BotMiner: Clustering Analysis of Network Traffic for Protocol- and Structure-Independent Botnet Detection
"... Botnets are now the key platform for many Internet attacks, such as spam, distributed denial-of-service (DDoS), identity theft, and phishing. Most of the current botnet detection approaches work only on specific botnet command and control (C&C) protocols (e.g., IRC) and structures (e.g., central ..."

We have implemented our BotMiner prototype system and evaluated it using many real network traces. The results show that it can detect real-world botnets (IRC-based, HTTP-based, and P2P botnets
A dynamical approach to gestural patterning in speech production.
- Ecological Psychology,
, 1989
"... In this article, we attempt to reconcile the linguistic hypothesis that speech involves an underlying sequencing of abstract, discrete, context-independent units, with the empirical observation of continuous, context-dependent interleaving of articulatory movements. To this end, we first review a p ..."

Approach-withdrawal and cerebral asymmetry: emotional expression and brain physiology I
- Journal of Personality and Social Psychology

"... In this experiment, we combined the measurement of observable facial behavior with simultaneous measures of brain electrical ctivity to assess patterns of hemispheric a tivation i different regions during the experience ofhappiness and disgust. Disgust was found to be associated with right-sided act ..."

XX The Rise of Social Bots
"... The Turing test asked whether one could recognize the behavior of a human from that of a computer al-gorithm. Today this question has suddenly become very relevant in the context of social media, where text constraints limit the expressive power of humans, and real incentives abound to develop human ..."

Characteristics related to content, network, sentiment, and temporal pat-terns of activity are imitated by bots but at the same time can
Patterns of Search: Analyzing and Modeling Web Query Refinement

Our analyses are derived from a large corpus of Web search queries extracted from server logs recorded by a popular Internet search service. We frame the modeling task in terms of pursuing an ..."

A critical role for the right fronto-insular cortex in switching between central-executive and default-mode networks.

, 2008

Cognitively demanding tasks that evoke activation in the brain's central-executive network (CEN) have been consistently shown to evoke decreased activation (deactivation) in the default-mode network (DMN). The neural mechanisms underlying this switch between activation and deactivation of larg ..."
