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.

Resolution limit in community detection [PDF]

Proceedings of the National Academy of Sciences, 2006
Detecting community structure is fundamental to clarify the link between structure and function in complex networks and is used for practical applications in many disciplines. A successful method relies on the optimization of a quantity called modularity

Determination of X-ray detection limit and applications in perovskite X-ray detectors. [PDF]

Nat Commun, 2021
X-ray detection limit and sensitivity are important figure of merits for perovskite X-ray detectors, but literatures lack a valid mathematic expression for determining the lower limit of detection for a perovskite X-ray detector. In this work, we present

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 ...

Fundamental Limitation on the Detectability of Entanglement [PDF]

Phys. Rev. Lett. 129, 230503 (2022), 2022
Entanglement detection is essential in quantum information science and quantum many-body physics. It has been proved that entanglement exists almost surely for a random quantum state, while the realizations of effective entanglement criteria usually consume exponential resources, and efficient criteria often perform poorly without prior knowledge. This

Modeling observations with a detection limit using a truncated normal distribution with censoring. [PDF]

BMC Med Res Methodol, 2020
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.
