, 2007 Magnetic activity in ultracool dwarfs, as measured in X-rays and H$\alpha$, shows a steep decline after spectral type M7-M8. So far, no L dwarf has been detected in X-rays. In contrast, L dwarfs may have higher radio activity than M dwarfs.

The spatial experiences of dwarfs within public spaces
Scandinavian Journal of Disability Research, 2015 Dwarfism is commonly defined as anyone 4ft 10? (147.32 cm) or below and whose short stature involves a medical condition [Adelson, M. B. 2005. 'The Lives of Dwarfs', xv. NJ: Rutgers University Press].

, 2013 We present initial results from a wide-field (30,000 deg^2) search for L/T transition brown dwarfs within 25 pc using the Pan-STARRS1 and WISE surveys. Previous large-area searches have been incomplete for L/T transition dwarfs, because these objects are

A kinematically Bifurcated Metamaterial for Integrated Logic Operation and Computing
Advanced Science, EarlyView.A family of 2n‐side kinematic polygonal modules with n decoupled inputs and 2n extreme configurations via kinematic bifurcation is proposed. It allows integrating seven basic logic gates on a quadrilateral module. Moreover, a minimized Parallel Computing Sum of Products function is developed, enabling all 2‐bit arithmetic (including division ...

Unique Na5−xSbSe Phase Enables High‐Rate Performance of Sb2Se3 Anodes in Na‐Ion Batteries
Advanced Energy Materials, EarlyView.The (de)sodiation mechanism of Sb2Se3 is revealed through advanced operando techniques and ab initio simulations and underscores the value of complementary methods in exploring battery mechanisms. A new Na5−xSbSe phase is identified as the final sodiation product of Sb2Se3 anodes in Na‐ion batteries (NIBs), which enables the remarkably high‐rate ...

Dust in the Photospheric Environment II. Effect on the Near Infrared Spectra of L and T Dwarfs
, 2004 We report an attempt to interpret the spectra of L and T dwarfs with the use of the Unified Cloudy Model (UCM). For this purpose, we extend the grid of the UCMs to the cases of log g = 4.5 and 5.5.
