Narrow scope for resolution-limit-free community detection [PDF]
Phys. Rev. E 84, 016114 (2011), 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. To overcome this issue, it was recently suggested that instead of comparing the network to a random null model, as is done in ...

Material Limitations on the Detection Limit in Refractometry [PDF]
Sensors 9, 8382 (2009), 2009 We discuss the detection limit for refractometric sensors relying on high-Q optical cavities and show that the ultimate classical detection limit is given by min{Dn} > eta with n+i*eta being the complex refractive index of the material under refractometric investigation.

New Photodetection Method Using Unbalanced Sidebands for Squeezed Quantum Noise in Gravitational Wave Interferometer [PDF]
Phys.Rev. D67 (2003) 122001, 2002 Homodyne detection is one of the ways to circumvent the standard quantum limit for a gravitational wave detector. In this paper it will be shown that the same quantum-non-demolition effect using homodyne detection can be realized by heterodyne detection with unbalanced RF sidebands.

Modeling Variables with a Detection Limit using a Truncated Normal Distribution with Censoring [PDF]
BMC Medical Research Methodology 20 (2020), 2019 When data are collected subject to a detection limit, observations below the detection limit may be considered censored. In addition, the domain of such observations may be restricted; for example, values may be required to be non-negative. We propose a regression method for censored observations that also accounts for domain restriction.
