ORIGINAL PAPER Synchronization Implies Seizure or Seizure Implies Synchronization?
"... Abstract Epileptic seizures are considered as abnormally hypersynchronous neuronal activities of the brain. The question is ‘‘Do hypersynchronous neuronal activities in a brain region lead to seizure or the hypersynchronous activ-ities take place due to the progression of the seizure?’ ’ We have exa ..."

examined the ECoG signals of 21 epileptic patients consisting of 87 focal-onset seizures by three different measures namely, phase synchronization, amplitude corre-lation and simultaneous occurrence of peaks and troughs. Each of the measures indicates that for a majority of the focal-onset seizures
Pregel: A system for large-scale graph processing
- IN SIGMOD
, 2010
"... Many practical computing problems concern large graphs. Standard examples include the Web graph and various social networks. The scale of these graphs—in some cases billions of vertices, trillions of edges—poses challenges to their efficient processing. In this paper we present a computational model ..."

is flexible enough to express a broad set of algorithms. The model has been designed for efficient, scalable and fault-tolerant implementation on clusters of thousands of commodity computers, and its implied synchronicity makes reasoning about programs easier. Distributionrelated details are hidden behind
Analysis of a local-area wireless network
, 2000
"... To understand better how users take advantage of wireless networks, we examine a twelve-week trace of a building-wide local-area wireless network. We analyze the network for overall user behavior (when and how intensively people use the network and how much they move around), overall network traffic ..."

for synchronous communication with others. In addition to these user-specific results, we find that peak throughput is usually caused by a single user and application. Also, while incoming traffic dominates outgoing traffic overall, the opposite tends to be true during periods of peak throughput, implying
Scope Consistency : A Bridge between Release Consistency and Entry Consistency
- In Proceedings of the 8th Annual ACM Symposium on Parallel Algorithms and Architectures
, 1996
"... The large granularity of communication and coherence in shared virtual memory systems causes problems with false sharing and extra communication. Relaxed memory consistency models have been used to alleviate these problems, but at a cost in programming complexity. Release Consistency (RC) and Lazy R ..."

Release Consistency (LRC) are accepted to offer a reasonable tradeoff between performance and programming complexity. Entry Consistency (EC) offers a more relaxed consistency model, but it requires explicit association of shared data objects with synchronization variables. The programming burden

Gradient Clock Synchronization
, 2004
"... We introduce the distributed gradient clock synchronization problem. As in traditional distributed clock synchronization, we consider a network of nodes equipped with hardware clocks with bounded drift. Nodes compute logical clock values based on their hardware clocks and message exchanges, and the ..."

Multimedia Synchronization
, 1995
"... This paper presents a hierarchical synchronization model for the description of the time relations and regimes necessary for the presentation of multimedia or animated data which have either natural or implied time dependencies. The model generalizes some previous multimedia synchronization models b ..."

Atrioventricular Synchronization and
"... Complete heart block implies an absolute independence between atria and ventricles that does not in fact always exist. Segers showed that, after complete block was artificially produced in the frog's heart, atria and ventricles would sometimes begin to beat exactly in phase, most commonly in a ..."

, 2001
"... Abstract--In recent years, wireless ad hoc networks have been a growing area of research. While there has been considerable research on the topic of routing in such networks, the topic of topology creation has not received due attention. This is because almost all ad hoc networks to date have been ..."

This fact implies that hosts are not able to communicate unless they have previously discovered each other by synchronizing their frequency hopping patterns. Thus, even if all nodes are within direct
Stability of continuous-time distributed consensus algorithms

This class of systems arises naturally in the context of distributed decision problems, coordination and rendezvous tasks and synchronization problems. The equilibri ..."
