Widespread variation in functional trait–vital rate relationships in tropical tree seedlings across a precipitation and soil phosphorus gradient [PDF]

, 2022
A fundamental assumption of functional ecology is that functional traits are related to interspecific variation in performance. However, the relationship between functional traits and performance is often weak or uncertain, especially for plants.

Genetic variation in the FMO2 gene: evolution & functional consequences [PDF]

, 2011
PhDFlavin-containing monooxygenase 2 (FMO2) is involved in the metabolism of xenobiotics, including therapeutic drugs. FMO2 exists in two forms: a functional and a non-functional form.

On Optimisation Approach to Velocity Field Determination in Image Processing Problems

Известия Иркутского государственного университета: Серия "Математика", 2018
The problem of determining the velocity field is investigated. This problem is considered by many authors in various formulations. The most well-known statement of the problem is proposed with the use of a concept of optical flow of constant distribution

Human feeding biomechanics: performance, variation, and functional constraints [PDF]

PeerJ, 2016
The evolution of the modern human (Homo sapiens) cranium is characterized by a reduction in the size of the feeding system, including reductions in the size of the facial skeleton, postcanine teeth, and the muscles involved in biting and chewing.

Dopamine inactivation efficacy related to functional DAT1 and COMT variants influences motor response evaluation [PDF]

, 2012
BACKGROUND: Dopamine plays an important role in orienting, response anticipation and movement evaluation. Thus, we examined the influence of functional variants related to dopamine inactivation in the dopamine transporter (DAT1) and catechol-O ...
