EBTM: An Enumeration-Based Thresholding Method for Degraded Circular Dot Segmentation. [PDF]

open access: yesSensors (Basel)
Circular dots are widely used in various measurement applications due to their inherent symmetry, ease of detection, and scalability. However, when degraded by factors such as specular highlights, low contrast, strong noise, or friction damage ...

Viability droplet digital polymerase chain reaction accurately enumerates probiotics and provides insight into damage experienced during storage

open access: yesFrontiers in Microbiology, 2022
Probiotics are typically enumerated by agar plate counting (PC) techniques. PC has several limitations including poor specificity, high variability, inability to enumerate dead cells, viable but non-culturable cells and cells in complex matrices ...

A generalization of the quadrangulation relation to constellations and hypermaps [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Constellations and hypermaps generalize combinatorial maps, $\textit{i.e.}$ embedding of graphs in a surface, in terms of factorization of permutations.

A bijection between planar constellations and some colored Lagrangian trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Constellations are colored planar maps that generalize different families of maps (planar maps, bipartite planar maps, bi-Eulerian planar maps, planar cacti, ...) and are strongly related to factorizations of permutations.

Counting the Undercounted: Enumerating Rural Homelessness in Canada

open access: yesInternational Journal on Homelessness, 2022
Until recently, homelessness in Canada was largely considered to be an urban phenomenon. This assumption has been reinforced by homelessness interventions that primarily focus on urban areas.

Implication and comparative study of Chinese and foreign examination method standards on mold and yeast enumeration in food

open access: yesZhongguo shipin weisheng zazhi, 2023
Molds and yeasts are common fungi that cause food contamination, and are also used as indicators to evaluate the quality of food hygiene. China has been conducting contamination surveillance of molds and yeasts in food since 1984, and has greatly ...

A Comprehensive Study of the Key Enumeration Problem

open access: yesEntropy, 2019
In this paper, we will study the key enumeration problem, which is connected to the key recovery problem posed in the cold boot attack setting. In this setting, an attacker with physical access to a computer may obtain noisy data of a cryptographic ...

Assessing Viability and Stress Tolerance of Probiotics—A Review

open access: yesFrontiers in Microbiology, 2022
The interest in probiotics has increased rapidly the latest years together with the global market for probiotic products. Consequently, establishing reliable microbiological methods for assuring the presence of a certain number of viable microorganisms ...
