Material Limitations on the Detection Limit in Refractometry [PDF]
Sensors, 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 {Δn} ≳ η with n + iη being the complex refractive index of the material under refractometric investigation.

Resolution limit in community detection [PDF]
Proceedings of the National Academy of Sciences, 2007 Detecting community structure is fundamental for uncovering the links between structure and function in complex networks and for practical applications in many disciplines such as biology and sociology. A popular method now widely used relies on the optimization of a quantity called modularity, which is a quality index for a partition of a network into

Information limits for detecting a subhypergraph [PDF]
Stat, 2021 We consider the problem of recovering a subhypergraph based on an observed adjacency tensor corresponding to a uniform hypergraph. The uniform hypergraph is assumed to contain a subset of vertices called as subhypergraph. The edges restricted to the subhypergraph are assumed to follow a different probability distribution than other edges.

Fundamental Limitation on the Detectability of Entanglement
Physical Review Letters, 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

Calibration of Tritium Microcalorimeter and Calorimetric Verification of Tritium Samples
Journal of Isotopes, 2023 Radioactive isotope decay gives off heat, which is an important basis for calculating the activity of radioactive isotope. In order to measure the heat emitted by tritium decay, the detection limit test, working curve calibration and tritium sample ...

Detecting deception: the scope and limits [PDF]
Trends in Cognitive Sciences, 2008 With the increasing interest in the neuroimaging of deception and its commercial application, there is a need to pay more attention to methodology. The weakness of studying deception in an experimental setting has been discussed intensively for over half a century.

Capacity limits in face detection [PDF]
Cognition, 2022 Face detection is a prerequisite for further face processing, such as extracting identity or semantic information. Those later processes appear to be subject to strict capacity limits, but the location of the bottleneck is unclear. In particular, it is not known whether the bottleneck occurs before or after face detection.

Spectral Assessment of Organic Matter with Different Composition Using Reflectance Spectroscopy
Remote Sensing, 2021 Soil surveys are critical for maintaining sustainable use of natural resources while minimizing harmful impacts to the ecosystem. A key soil attribute for many environmental factors, such as CO2 budget, soil fertility and sustainability, is soil organic ...
