Superstar musician Wyclef Jean, a native of Haiti, has helped raise over $400,000 for his native country, thanks to text-message donations.

Impressive. Really nice work!!!

This is related to the "Verified Software" item in NewScientist's list of ideas that will change science. At the link below you'll find the text of the patents being auctioned: http://icapoceantomo.com/item-for-sale/exclusive-license-related-improved-methodology-formally-developing-control-systems :) Patent #7,627,538 ("Swarm autonomic agents with self-destruct capability") makes for quite an interesting read: "This invention relates generally to artificial intelligence and, more particularly, to architecture for collective interactions between autonomous entities." "In some embodiments, an evolvable synthetic neural system is operably coupled to one or more evolvable synthetic neural systems in a hierarchy." "In yet another aspect, an autonomous nanotechnology swarm may comprise a plurality of workers composed of self-similar autonomic components that are arranged to perform individual tasks in furtherance of a desired objective." "In still yet another aspect, a process to construct an environment to satisfy increasingly demanding external requirements may include instantiating an embryonic evolvable neural interface and evolving the embryonic evolvable neural interface towards complex complete connectivity." "In some embodiments, NBF 500 also includes genetic algorithms (GA) 504 at each interface between autonomic components. The GAs 504 may modify the intra-ENI 202 to satisfy requirements of the SALs 502 during learning, task execution or impairment of other subsystems."

An interesting (free) journal on philosophy, with even some article with mathematics and physics !

Reading the titles somehow reminds me of the most important webpage of the ACT: the Advanced Concepts Generator :-)

have you seen the 2 articles on canonical GR ...!

If you get suspicious text you can have an automated check. However, I suggest to remove any references chapter since they boost the amount of hits. My last Ariadna report has a plagiarism rate of 8.7%. Anyone higher?

Big data analytic systems are reputed to be capable of finding a needle in a universe of haystacks without having to know what a needle looks like. The very best ways to sort large databases of unstructured text is to use a technique called Latent Dirichlet allocation (LDA). Unfortunately, LDA is also inaccurate enough at some tasks that the results of any topic model created with it are essentially meaningless, according to Luis Amaral, a physicist whose specialty is the mathematical analysis of complex systems and networks in the real world and one of the senior researchers on the multidisciplinary team from Northwestern University that wrote the paper. Even for an easy case, big data analysis is proving to be far more complicated than many of the companies selling analysis software want people to believe.

Most of those companies are using outdated algorithms like this LDA and just apply them like retards on those huge datasets. Of course they're going to come out with bad solutions. No amount of data can make up for bad algorithms.

Researchers in the US have built a new type of solar cell that emits light as well as absorbs it, making it the most efficient solar cell ever developed. The efficiency of their prototype cell allows it to convert 28.6% of the Sun's energy into electricity.

well, the text is at best misleading ... the most efficient solar cells are well over 35% and approach the 40s with concentration! what they have done is to increase the limit of a single junction cell it seems to me ... still, nteresting though from text most details on how this was done are missing ... paper is not yet published, correct?

I learn of it in a workshop few weaks ago. It's on GaAs and I think that the key theoretical aspects are explained here: http://arxiv.org/abs/1106.1603

not sure where they got the "industry" from but otherwise our text indeed

Intuitive, well documented, and very powerful. A library to keep an eye on. Check the example Belgian elections, June 13, 2010 - Twitter opinion mining

cool. It would be very to make a review of interesting photonic properties we could benefit from nature, and the possible use for space. It's nice to see that some structured can already be replicated...! Is there a structure to give angulaer momentum to light ?

Useful information that may help improve the choice of words etc in our documents

The best post of Slashdot: "Genetic Algorithms are like the AI equivalent of text editors... everybody has spent a weekend writing one at some point."

Statistical methods of text analysis have become increasingly sophisticated over the years. A good example is automated topic analysis using latent models, two variants of which are Probabilistic latent semantic analysis and Latent Dirichlet Allocation.
