Increasing pattern recognition accuracy for chemical sensing by evolutionary based drift compensation [PDF]

open access: yes, 2011
Artificial olfaction systems, which mimic human olfaction by using arrays of gas chemical sensors combined with pattern recognition methods, represent a potentially low-cost tool in many areas of industry such as perfumery, food and drink production ...

Effect of Olfactory Training in COVID‐19 Related Olfactory Dysfunction—A Placebo‐Controlled Trial

open access: yesThe Laryngoscope, EarlyView.
This randomized placebo‐controlled trial evaluates the effectiveness of olfactory training in patients with post‐COVID‐19 olfactory dysfunction. The results showed no significant improvement in olfactory function after 12 weeks of training. The presence of parosmia was associated with reduced effectiveness of the olfactory training.

Olfaction in raptors [PDF]

open access: yesZoological Journal of the Linnean Society, 2019
AbstractRaptors from the orders Accipitriformes and Falconiformes have been considered to rely principally on vision. Historically, this assumption has led scientists to discount any possible sense of smell in these birds, until work on cathartid vultures indicated that these species at least rely on olfaction to find carrion.

Physiological barriers to oral intake in survivors of critical illness: A scoping review

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Oral nutrition is the predominant mode of nutrition delivery on the post–Intensive Care Unit (ICU) ward; yet, it is associated with lower intake than via enteral or parenteral nutrition. There are limited data on barriers that influence oral intake in ICU survivors.

The nonclassical mereology of olfactory experiences [PDF]

open access: yes, 2019
While there is a growing philosophical interest in analysing olfactory experiences, the mereological structure of odours considered in respect of how they are perceptually experienced has not yet been extensively investigated.

Perceiving and Knowing as Activities [PDF]

open access: yes, 2016
According to the tradition of most empiricists, perception is the basis for all our knowledge (at least of the world). The tradition also assumes that perception by humans is a passive activity resulting in some static states pertaining perception and ...

Antbears and underground melons: A highly specialized seed dispersal mutualism mediated by scent

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Seed dispersal is critical for the establishment and persistence of populations of most plant species. We investigated the seed dispersal biology of an African melon, Cucumis humifructus, which is closely related to cultivated cucumbers and watermelons but differs in that it buries its fruits deep underground.

Distinct expression profiles and different functions of odorant binding proteins in Nilaparvata lugens Stål.

open access: yesPLoS ONE, 2011
BackgroundOdorant binding proteins (OBPs) play important roles in insect olfaction. The brown planthopper (BPH), Nilaparvata lugens Stål (Delphacidae, Auchenorrhyncha, Hemiptera) is one of the most important rice pests.
