Solar Energy Conversion into H2 Energy Using Ferrites

A cation-excess (Ni,Mn) ferrite N~o.~zMno.51Fe2.0504.0 with a single phase was synthesized by heating the mixture of corresponding metal salts and oxide in 5% 02175% C02120% N2 gas mixture for 18h at 1100C. It could be thermochemically activated to form a cation-excess ferrite Nio,5z~l+s~Mno.51~l+6~Fe2~05~1+6~0440 in N2 gas at elevated temperature: The ( value was 0.03 1 at 1100C. The activated...

Teaching Computer Scientists to Make Use

Scenario-based design is a family of techniques in which the use of a future system is concretely described at an early point in the development process. Narrative descriptions of envisioned usage episodes are then employed in a variety of ways to guide the development of the system that will enable these use experiences. Scenarios are stories of users and their behaviour, which makes them an e...

Can Cognitive Scientists Help Computers Recognize Irony?

This workshop aims to bring together researchers in cognitive science and computer science with a shared interest in irony. Irony detection is an especially difficult problem for natural language processing. Unlike other types of classification tasks, the difficulty of identifying irony is not alleviated by ‘throwing more data’ at the problem. Rather, it seems a different kind of data is needed...

Mnemonic microRNAs help make memories

L earning and memory depend on the brain’s plasticity, its ability to rewire itself. Lippi et al. reveal that two microRNAs (miRNAs) help the brain maintain this fl exibility by dismantling unneeded synapses between neurons (1). When a rat memorizes the route through a maze or a singer learns the lyrics to a song, the neural changes in their brains typically include growth or modifi cation of d...
