Efficient counting of degree sequences [PDF]

open access: yesDiscrete 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

open access: yesScientific 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

Full counting statistics of vibrationally assisted electronic conduction: Transport and fluctuations of thermoelectric efficiency [PDF]

open access: yes, 2015
We study the statistical properties of charge and energy transport in electron conducting junctions with electron-phonon interactions, specifically, the thermoelectric efficiency and its fluctuations.

Comparison of traditional methods versus SAFEcount for filling prescriptions: A pilot study of an innovative pill counting solution in eSwatini.

open access: yesPLoS ONE, 2019
BACKGROUND:Packaging medications is a crucial component of health system efficiency and quality. In developing countries, medications often arrive in bulk containers that need to be counted by hand.

SiPM used as fast Photon-Counting Module and for Multiphoton Detection

open access: yes, 2007
We demonstrate fast counting and multiphoton detection abilities of a Silicon Photo Multiplier (SiPM). In fast counting mode we are able to detect two consecutive photons separated by only 2.3 ns corresponding to 430 MHz.

MEMORY EFFICIENT HYPERELLIPTIC CURVE POINT COUNTING [PDF]

open access: yesInternational Journal of Number Theory, 2011
In recent algorithms that use deformation in order to compute the number of points on varieties over a finite field, certain differential equations of matrices over p-adic fields emerge. We present a novel strategy to solve this kind of equations in a memory efficient way.

Efficient Counting of Network Motifs [PDF]

open access: yes2010 IEEE 30th International Conference on Distributed Computing Systems Workshops, 2010
Counting network motifs has an important role in studying a wide range of complex networks. However, when the network size is large, as in the case of Internet Topology and WWW graphs counting the number of motifs becomes prohibitive. Devising efficient motif counting algorithms thus becomes an important goal.

Influence of Background on Apparent Counting Efficiency in Radioactivity Analysis

open access: yesHe huaxue yu fangshe huaxue
In radioactivity analysis, counting efficiency(E) and background(to be precise, it should be deterministic background) are usually discussed, but apparent counting efficiency(E') and random background are rarely mentioned.
