Radioiodinated lipoproteins: absorption of 125I radioactivity by high density solutions.

Journal of Lipid Research, 1975
Concentrations of potassium bromide commonly used for separation of lipoproteins were shown to cause absorption of 125I and thus reduce the counting efficiency of the labeled lipoproteins.

Quantum-scissors device for optical state truncation: A proposal for practical realization [PDF]

, 2001
We propose a realizable experimental scheme to prepare superposition of the vacuum and one-photon states by truncating an input coherent state. The scheme is based on the quantum scissors device proposed by Pegg, Phillips, and Barnett [Phys. Rev.

Efficient counting of degree sequences [PDF]

Discrete Mathematics, 2019
Novel dynamic programming algorithms to count the set $D(n)$ of zero-free degree sequences of length $n$, the set $D_c(n)$ of degree sequences of connected graphs on $n$ vertices and the set $D_b(n)$ of degree sequences of biconnected graphs on $n$ vertices exactly are presented.

Time-domain based evaluation of detection efficiency in liquid scintillation counting

Scientific Reports, 2021
This work explores the distribution of time intervals between signals from the photomultiplier tubes (PMTs) of a liquid scintillation counting (LSC) system when a scintillation burst caused by an ionizing particle is detected. This distribution is termed

A Tea Buds Counting Method Based on YOLOv5 and Kalman Filter Tracking Algorithm

Plant Phenomics, 2023
The tea yield estimation provides information support for the harvest time and amount and serves as a decision-making basis for farmer management and picking. However, the manual counting of tea buds is troublesome and inefficient.
