Data management for stateful web applications is extremely challenging. Applications must scale as they grow in popularity, serve their content with low-latency on a global scale, and have high availability, even in the face of hardware failures. This need has given rise in recent years to a new class of internet-scale data management systems

The source-location privacy problem in Wireless Sensor Networks has been traditionally tackled by the creation of random routes for every packet transmitted from the source nodes to the base station. These schemes provide a considerable protection level at a high cost in terms of message delivery time and energy consumption. This overhead is due to the fact that the data routing process is done in a blind way, without knowledge about the location of the attacker

Ants are generally believed to follow an intensive work routine.

The construction of gene regulatory networks from expression data is one of the most important issues in systems biology research. However, building such networks is a tedious task, especially when both the number of genes and the complexity of gene regulation increase. In this work, we adopt the S-system model to represent the gene network and establish a methodology to infer the model

One of the best ways to speed up your work in Excel, especially repetitive tasks, is to record macros that perform the things you do over and over. Another way is to use buttons to tell Excel to do things that you may not always remember how to do.
