The luminosities of the brightest cluster galaxies and brightest satellites in SDSS groups

open access: yes, 2012
We show that the distribution of luminosities of Brightest Cluster Galaxies in an SDSS-based group catalog suggests that BCG luminosities are just the statistical extremes of the group galaxy luminosity function.

Template‐Directed Growth of Palladium Nanoparticles in Holey Single‐Layer Graphene for High‐Performance Room‐Temperature Hydrogen Sensing

open access: yesSmall Structures, Volume 7, Issue 1, January 2026.
A template‐directed method produces holey single‐layer graphene with uniform 2.7 nm pores while preserving sp2 conjugation. These reactive edges confine the autoreductive growth of palladium nanoparticles without external reducing agents. The resulting Pd@HG hybrid delivers ultrahigh sensitivity, low detection limits, fast response/recovery, and stable

Spanning Trees in Random Satisfiability Problems

open access: yes, 2006
Working with tree graphs is always easier than with loopy ones and spanning trees are the closest tree-like structures to a given graph. We find a correspondence between the solutions of random K-satisfiability problem and those of spanning trees in the ...

Pop up satellite tags impair swimming performance and energetics of the European eel (Anguilla anguilla).

open access: yesPLoS ONE, 2011
Pop-up satellite archival tags (PSATs) have recently been applied in attempts to follow the oceanic spawning migration of the European eel. PSATs are quite large, and in all likelihood their hydraulic drag constitutes an additional cost during swimming ...

Microbial and Chemical Drivers of Indoor Air Quality in Educational Environments

open access: yesIndoor Air, Volume 2026, Issue 1, 2026.
Indoor air quality (IAQ) in educational facilities is shaped by a dynamic interplay of microbial, chemical and physical factors, all of which influence health and cognitive performance. This study explored IAQ in university classrooms by combining microbiological, chemical and physical measurements to better understand microbial–chemical interactions ...
