Information limits for detecting a subhypergraph [PDF]

open access: yesStat, 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.

Luminescent method for determination of nanoscale particles of rare earth elements with sulfosalicylic acid derivatives

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022
It was of interest to search for luminescent reactions to terbium in complexes with sulfosalicylic acid derivatives and to enhance them by studying the effect of third components (aminopolycarboxylic acids, organic bases and surfactants).

Molecularly Imprinted Electrochemical Sensor-Based Fe2O3@MWCNTs for Ivabradine Drug Determination in Pharmaceutical Formulation, Serum, and Urine Samples

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Ivabradine hydrochloride (IVR) is a medically important drug because of its ability to lower the heart rate. Techniques reported for IVR determination were expensive, laborious, besides being of poor selectivity.

Measurements below the detection limit.

open access: yesTidsskrift for Den Norske Laegeforening, 2022
Let's start with an example: Figure 1 shows a fictional dataset of measurements of serum levels of a substance in two patient groups. The crosses indicate the actual values, but only those above the lower detection limit can be measured. We know how many

In-vitro Study for Cerenkov Luminescence Imaging Application in Hepatic Metastasectomy

open access: yesFrontiers in Physics, 2021
Cerenkov luminescence imaging (CLI) has been recently proposed as a method to visualize surgical margins in the operating theater, immediately after resection, to allow refining surgery in a single procedure. Our group is preparing a pilot clinical study

Review on the Analysis and Testing Method of Typical Plant Growth Regulators in Environment

open access: yesYankuang ceshi, 2023
Plant growth regulators (PGRs) are defined as naturally occurring or artificially synthesized compounds. The functions of PGRs mainly include accelerating or delaying seed germination, breaking plant dormancy, stimulating or reducing bud elongation ...

Quantitative Spectrochip-Coupled Lateral Flow Immunoassay Demonstrates Clinical Potential for Overcoming Coronavirus Disease 2019 Pandemic Screening Challenges

open access: yesMicromachines, 2021
As coronavirus disease 2019 (COVID-19) continues to spread around the world, the establishment of decentralized severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) diagnostics and point-of-care testing is invaluable.
