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.

imGLAD: accurate detection and quantification of target organisms in metagenomes [PDF]
PeerJ, 2018 Accurate detection of target microbial species in metagenomic datasets from environmental samples remains limited because the limit of detection of current methods is typically inaccessible and the frequency of false-positives, resulting from inadequate ...

Highly Sensitive Detection of Chymotrypsin Based on Metal Organic Frameworks with Peptides Sensors
Biosensors, 2023 In this study, peptides and composite nanomaterials based on copper nanoclusters (CuNCs) were used to detect chymotrypsin. The peptide was a chymotrypsin-specific cleavage peptide. The amino end of the peptide was covalently bound to CuNCs.

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.
