Bimodality of Freeman's Law [PDF]
A cluster sample of 62 galaxies complete to M(B)=-16.5 mag has been observed at B,R,I,K' bands with imaging detectors. The distribution of exponential disk central surface brightnesses is found to be bimodal. The bimodality is particularly significant at K' because obscuration is not a problem and because the high surface brightness galaxies are redder

The properties of chromium electrodeposited with programmed currents. Part I. Direct current
The electrodeposition of chromium in programmed direct current (DC) was investigated in the regime of high current density (77 A dm-2). Chromium was deposited in a system of plane-parallel electrodes in chromic-sulphuric acid solution, on specimens of ...

Boosting Illuminant Estimation in Deep Color Constancy through Enhancing Brightness Robustness [PDF]
Color constancy estimates illuminant chromaticity to correct color-biased images. Recently, Deep Neural Network-driven Color Constancy (DNNCC) models have made substantial advancements. Nevertheless, the potential risks in DNNCC due to the vulnerability of deep neural networks have not yet been explored.

Gas, Stars and Baryons in Low Surface Brightness Galaxies [PDF]
Recent surveys have discovered hundreds of low surface brightness galaxies in the local (z < 0.1) Universe. Plots of the surface brightness distribution (the space density of galaxies plotted against central surface brightness) show a flat distribution from the bright-end cutoff of 21.65 through the current observational limit of 25.0 B mag arcsec^{-2}.

Formation of multi-solitons and vortex bright solitons in Bose-condensed alkali-metal atoms [PDF]
Formation of multi-solitons and vortex bright solitons in Bose-condensed alkali-metal atoms is analyzed by using the nonpolynomial Schordinger equation. A train of bright solitons is obtained from an axially homogeneous Bose-Einstein condensate by a sudden change of the scattering length from repulsive to attractive.
