No more Slave-Gangs: Varro, De Re Rustica 1.2.20–1

No slave to sex.

Fully asexual lineages cannot purge accumulating mutations from their genome through recombination. In ancient asexuals that have persisted without sex for millions of years, this should lead to high allelic divergences (the 'Meselson effect') as has been shown for bdelloid rotifers. Homogenizing mechanisms can counter this effect, resulting in low genetic diversity within and between individua...

Social Network De-anonymization: More Adversarial Knowledge, More Users Re-Identified?

Following the trend of data trading and data publishing, many online social networks have enabled potentially sensitive data to be exchanged or shared on the web. As a result, users’ privacy could be exposed to malicious third parties since they are extremely vulnerable to de-anonymization attacks, i.e., the attacker links the anonymous nodes in the social network to their real identities with ...

De Re and De Se

1. De re thought and token-reflexivity There is an intuitive contrast between descriptive thoughts about an object (e.g. the thought that the strongest man in the world can lift 150 kilos) and 'nondescriptive' or 'de re' thoughts about an object (e.g. the thought that that man is drunk). But it is not easy to make the contrast explicit without going stipulative. The distinction between de re th...

Solving Re-entrant No-wait Flow Shop Scheduling Problem

In this study, we consider the production environment of no-wait reentrant flow shop with the objective of minimizing makespan of the jobs. In a reentrant flow shop, at least one job should visit at least one of the machines more than once. In a no-wait flowshop scheduling problem, when the process of a specific job begins on the first machine, it should constantly be processed without waiting ...
