Is cannabis a stepping-stone for cocaine?

This paper uses a unique dataset on the inhabitants of Amsterdam, to study the dynamics of the consumption of cannabis and cocaine. People are most likely to start using that drugs at ages 18-20 and 20-25. An analysis of the starting rates shows some evidence of cannabis being a "stepping-stone" for cocaine. However, the fact that some individuals use both cannabis and cocaine has to do mostly ...

A Stepping Stone to Pluripotency

Somatic cells can be reprogrammed into pluripotent stem cells via either expression of transcription factors or addition of small molecule chemicals only. Zhao et al. reveal a unique intermediate state during chemical reprogramming allowing a significant improvement in its efficiency and kinetics.

Intelligent Network-Based Stepping Stone Detection Approach

This research intends to introduce a new usage of Artificial Intelligent (AI) approaches in Stepping Stone Detection (SSD) fields of research. By using Self-Organizing Map (SOM) approaches as the engine, through the experiment, it is shown that SOM has the capability to detect the number of connection chains that involved in a stepping stones. Realizing that by counting the number of connection...
