BACKGROUND Approximately one-third of all borderline ovarian tumours (BOT) are diagnosed in patients with child-bearing potential. Detailed information regarding their specific characteristics and prognostic factors is limited. METHODS Clinical parameters of BOT patients treated between 1998 and 2008 in 24 German centres were retrospectively investigated. Central pathology review and prospect...

Swarm intelligence is the discipline that deals with natural and artificial systems composed of many individuals that coordinate using decentralized control and self-organization. The discipline focuses on the collective behaviors that result from the local interactions of the individuals with each other and with their environment. Examples of systems studied by swarm intelligence are colonies ...

A distinguishing characteristic of bots is their ability to establish a command and control (C&C) channel. The typical approach to build detection models for C&C traffic and to identify C&C endpoints (IP addresses and domains of C&C servers) is to execute a bot in a controlled environment and monitor its outgoing network connections. Using the bot traffic, one can then craft signatures that mat...

The scheduling and execution of bag-of-tasks applications (BoTs) in Clouds is performed on sets of virtualized Cloud resources that start being exhausted right after their allocation disregarding whether tasks are being executed. In addition, BoTs may be executed in potentially heterogeneous sets of Cloud resources, which may be either previously allocated for a different and fixed number of ho...

The rich functionality of modern personal computers combined with ineffective deployment of practical security solutions opens the door to a wide variety of attacks and exploits on their applications. This in turn has led to an extremely widespread propagation of malware, or software designed to perform hostile activities without the owner’s consent. An increasingly common phenomenon is for mal...

Internet bots have been widely used for various beneficial and malicious activities on the web. In this paper we provide new insights into a new kind of bot termed as web spambot which is primarily used for spreading spam content on the web. To gain insights into web spambots, we developed a tool (HoneySpam 2.0) to track their behaviour. This paper presents two main contributions, firstly it de...

O Poeta Artificial is a bot that tweets poems, in Portuguese, inspired by the latest Twitter trends. Built on top of PoeTryMe, a poetry generation platform, so far it had only produced poems based on a set of keywords in tweets about a trend. This paper presents recently implemented features for increasing the connection between the produced text and the target trend through the reutilisation a...

Botnets are security threat now days, since they tend to perform serious internet attacks in vast area through the compromised group of infected machines. The presence of command and control mechanism in botnet structure makes them stronger than traditional attacks. Over course of the time botnet developer have switched to more advanced mechanism to evade each of which new detection methods and...

In this paper, we study coordinated motion in a swarm robotic system, called a swarm-bot. A swarm-bot is a self-assembling and self-organising artifact, composed of a swarm of s-bots, mobile robots with the ability to connect to and disconnect from each other. The swarm-bot concept is particularly suited for tasks that require all-terrain navigation abilities, such as space exploration or rescu...
