Liquid scintillation counting: A new procedure for determining counting efficiency

The International Journal of Applied Radiation and Isotopes, 1967
Abstract A new approach is presented for correcting for quenching in liquid scintillation counting with a two-channel instrument. The square root of the number of counts in one channel is taken as a function of the square root of the counts in the other channel. This has the advantages over the widely used “channels ratio” method that a statistically

Efficient techniques for k-mer counting

2015 IEEE 5th International Conference on Computational Advances in Bio and Medical Sciences (ICCABS), 2015
A large number of bioinformatics applications require counting of k-length substrings in genetically important long strings. K-mer counting generates the frequencies of each k-length substring in genome sequences. Genome assembly, repeat detection, multiple sequence alignment, error detection, and many other related applications use k-mer counting as a

Efficient Crowd Counting via Dual Knowledge Distillation

IEEE Transactions on Image Processing
Most researchers focus on designing accurate crowd counting models with heavy parameters and computations but ignore the resource burden during the model deployment. A real-world scenario demands an efficient counting model with low-latency and high-performance.

Transmission efficiency in photon counting channels

IEEE Transactions on Communications, 1989
An investigation is presented of the maximum transmission efficiency that can be reached over an ideal photon counting channel, having fixed the bandwidth expansion factor. First, the ideal situation, represented by C.E. Shannon's (1959) theorem for discrete channels, is analyzed.
