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.

Discrete symmetries and efficient counting of operators

open access: yesJournal of High Energy Physics, 2023
Abstract We present DECO (“Discrete and Efficient Counting of Operators”), an implementation of the Hilbert series to enumerate subleading operator bases for SMEFT-like EFTs with symmetry groups as typically found in flavour and BSM physics.

Measurement of the Neutron Lifetime by Counting Trapped Protons in a Cold Neutron Beam

open access: yes, 2004
A measurement of the neutron lifetime $\tau_{n}$ performed by the absolute counting of in-beam neutrons and their decay protons has been completed. Protons confined in a quasi-Penning trap were accelerated onto a silicon detector held at a high potential

Efficient Knowledge Compilation Beyond Weighted Model Counting

open access: yesTheory and Practice of Logic Programming, 2022
AbstractQuantitative extensions of logic programming often require the solution of so called second level inference tasks, that is, problems that involve a third operation, such as maximization or normalization, on top of addition and multiplication, and thus go beyond the well-known weighted or algebraic model counting setting of probabilistic logic ...

METRIC CHARACTERISTICS OF VARIOUS METHODS FOR NUMERICAL DENSITY ESTIMATION IN TRANSMISSION LIGHT MICROSCOPY – A COMPUTER SIMULATION

open access: yesImage Analysis and Stereology, 2011
In the introduction the evolution of methods for numerical density estimation of particles is presented shortly. Three pairs of methods have been analysed and compared: (1) classical methods for particles counting in thin and thick sections, (2) original

Measuring the absolute photo detection efficiency using photon number correlations

open access: yes, 2006
We present two methods for determining the absolute detection efficiency of photon-counting detectors directly from their singles rates under illumination from a nonclassical light source.

An Improved Pig Counting Algorithm Based on YOLOv5 and DeepSORT Model

open access: yesSensors, 2023
Pig counting is an important task in pig sales and breeding supervision. Currently, manual counting is low-efficiency and high-cost and presents challenges in terms of statistical analysis.
