Odor Intensity Detection and Evaluation Method Considering Odor Prediction Model

open access: yesChemical Engineering Transactions, 2018
Volatile organic pollutants produced during people’s living and production are the main source of stink pollution. The rapid and efficient detection and evaluation of odors in gas through effective methods is a key step for improving the level of ...

Rapid odor processing by layer 2 subcircuits in lateral entorhinal cortex

open access: yeseLife, 2022
Olfactory information is encoded in lateral entorhinal cortex (LEC) by two classes of layer 2 (L2) principal neurons: fan and pyramidal cells. However, the functional properties of L2 cells and how they contribute to odor coding are unclear.

Learning to predict target location with turbulent odor plumes

open access: yeseLife, 2022
Animal behavior and neural recordings show that the brain is able to measure both the intensity and the timing of odor encounters. However, whether intensity or timing of odor detections is more informative for olfactory-driven behavior is not understood.

Visual Analysis of Odor Interaction Based on Support Vector Regression Method

open access: yesSensors, 2020
The complex odor interaction between odorants makes it difficult to predict the odor intensity of their mixtures. The analysis method is currently one of the factors limiting our understanding of the odor interaction laws.

Neural Coding of Perceived Odor Intensity. [PDF]

open access: yeseNeuro, 2015
AbstractStimulus intensity is a fundamental perceptual feature in all sensory systems. In olfaction, perceived odor intensity depends on at least two variables: odor concentration; and duration of the odor exposure or adaptation. To examine how neural activity at early stages of the olfactory system represents features relevant to intensity perception,

Identification of odor emission sources in urban areas using machine learning-based classification models

open access: yesAtmospheric Environment: X, 2022
Odor-causing substances are generated by various emission sources in urban areas. Recently, urbanization has greatly increased the density of odor emission facilities, implying the identification of odorants emission source is challenging.

Objective Odor Assessment in Patients with Osmidrosis

open access: yesPlastic and Reconstructive Surgery, Global Open, 2022
Background:. No standards for the assessment of axillary odor intensity and the effects of therapy for osmidrosis have been established. This study presents an objective method for assessing odor severity in patients with osmidrosis and investigates the ...

Estimating Exposure Intensity Based on Odor

open access: yesAnnals of Work Exposures and Health, 2021
Abstract The odor detection threshold for a chemical typically varies widely across population members, and the values can be described by a lognormal distribution. Assuming that the parameters of a chemical’s odor detection threshold distribution can be estimated, a method is presented to retrospectively estimate exposure intensity ...

Research on Odor Interaction between Aldehyde Compounds via a Partial Differential Equation (PDE) Model

open access: yesSensors, 2015
In order to explore the odor interaction of binary odor mixtures, a series of odor intensity evaluation tests were performed using both individual components and binary mixtures of aldehydes.
