Bacteriophage Enumeration and Detection Methods

open access: yesFrontiers in Microbiology, 2020
Application of phages as alternative antimicrobials to combat pathogenic bacteria and their association to a healthy gut microbiome has prompted a need for precise methods for detection and enumeration of phage particles.

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

open access: yesSensors
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 ...

Enumeration and Representation Theory of Spin Space Groups [PDF]

open access: yesPhysical Review X, 2023
Fundamental physical properties, such as phase transitions, electronic structures, and spin excitations, in all magnetic ordered materials, were ultimately believed to rely on the symmetry theory of magnetic space groups.

HUGE: An Efficient and Scalable Subgraph Enumeration System [PDF]

open access: yesSIGMOD Conference, 2021
Subgraph enumeration is a fundamental problem in graph analytics, which aims to find all instances of a given query graph on a large data graph. In this paper, we propose a system called HUGE to efficiently process subgraph enumeration at scale in the ...

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.

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 ...

Deep Reinforcement Learning for Join Order Enumeration [PDF]

open access: yesaiDM@SIGMOD, 2018
Join order selection plays a significant role in query performance. However, modern query optimizers typically employ static join order enumeration algorithms that do not incorporate feedback about the quality of the resulting plan.

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 ...
