An Electrically Conducting Li-Ion Metal-Organic Framework.

Metal-organic frameworks (MOFs) have emerged as an important, yet highly challenging class of electrochemical energy storage materials. The chemical principles for electroactive MOFs remain, however, poorly explored because precise chemical and structural control is mandatory. For instance, no anionic MOF with a lithium cation reservoir and reversible redox (like a conventional Li-ion cathode) has been synthesized to date.

Gaussian-noise discrimination and its relation to auditory object formation.

This study used a same/different experiment to assess the ability of human listeners to discriminate Gaussian-noise tokens with a spectral range of 350-850 Hz and a duration of 50 ms. For this duration, discrimination ability is high. However, when an identical 200-ms noise fringe with the same statistical properties as the 50-ms target tokens is appended to the end of the two target tokens, listeners show very poor discrimination.

On the ability to discriminate Gaussian-noise tokens or random tone-burst complexes.

This study investigated factors that influence a listeners' ability to discriminate Gaussian-noise stimuli in a same-different discrimination paradigm. The first experiment showed that discrimination ability increased with bandwidth for noise durations up to 100 ms. Duration had a nonmonotonic influence on performance, with a decrease in discriminability for stimuli longer than 40 ms.
