A note on investigating co‐occurrence patterns and dynamics for many species, with imperfect detection and a log‐linear modeling parameterization [PDF]

open access: yesEcology and Evolution, 2021
Patterns in, and the underlying dynamics of, species co‐occurrence is of interest in many ecological applications. Unaccounted for, imperfect detection of the species can lead to misleading inferences about the nature and magnitude of any interaction.

Realizing the value in “non-standard” parts of the qPCR standard curve by integrating fundamentals of quantitative microbiology

open access: yesFrontiers in Microbiology, 2023
The real-time polymerase chain reaction (PCR), commonly known as quantitative PCR (qPCR), is increasingly common in environmental microbiology applications. During the COVID-19 pandemic, qPCR combined with reverse transcription (RT-qPCR) has been used to

Anomaly Detection for Log Sequence Based on Improved Temporal Convolutional Network [PDF]

open access: yesJisuanji gongcheng, 2020
Existing anomaly detection models for log sequence based on recurrent neural network perform well for shorter sequences,but underperform for long sequences.To address the problem,this paper proposes a general anomaly detection framework for log sequences

Multivariate Count Data Models for Time Series Forecasting

open access: yesEntropy, 2021
Count data appears in many research fields and exhibits certain features that make modeling difficult. Most popular approaches to modeling count data can be classified into observation and parameter-driven models. In this paper, we review two models from
