Narrow scope for resolution-limit-free community detection
, 2011 Detecting communities in large networks has drawn much attention over the years. While modularity remains one of the more popular methods of community detection, the so-called resolution limit remains a significant drawback.

Detection-Response Task—Uses and Limitations [PDF]
Sensors, 2018 The Detection-Response Task is a method for assessing the attentional effects of cognitive load in a driving environment. Drivers are presented with a sensory stimulus every 3–5 s, and are asked to respond to it by pressing a button attached to their finger.

Limits to the Mass and the Radius of the Compact Star in SAX J1808.4--3658 and Their Implications [PDF]
, 2001 We show that a survey of equations of state and observations of X-ray pulsations from SAX J1808.4-3658 give 2.27 solar mass as the upper limit of the compact star mass. The corresponding upper limit of the radius comes out to be 9.73 km.
