Climatic impact, future biomass production, and local adaptation of four switchgrass cultivars

open access: yesGCB Bioenergy, 2019
Previous studies have shown that switchgrass has a wide range of genetic variation and that productivity is linked to local adaptation to the location of origin for many cultivars.

Distributed processing of color and form in the visual cortex

open access: yesFrontiers in Psychology, 2014
To what extent does the visual system process color and form separately? Proponents of the segregation view claim that distinct regions of the cortex are dedicated to each of these two dimensions separately.

Can ERAP1 and ERAP2 Form Functional Heterodimers? A Structural Dynamics Investigation

open access: yesFrontiers in Immunology, 2022
Endoplasmic reticulum aminopeptidases 1 and 2 (ERAP1 and ERAP2) play important roles in the generation of antigenic peptides presented by Major Histocompatibility Class I (MHCI) molecules and indirectly regulate adaptive immune responses.

On the stability of a multiplicative type sum form functional equation

open access: yesRatio Mathematica, 2021
In this paper we intend to discuss the stability of a sum form functional equation \begin{align*} \sum\limits\limits^n_{i=1}\sum\limits\limits^m_{j=1}f\left(p_iq_j\right)=\sum\limits\limits^n_{i=1}k\left(p_i\right)\sum\limits\limits^m_{j=1}q^{\beta }_j ...

Functional modulation of cardiac form through regionally confined cell shape changes. [PDF]

open access: yesPLoS Biology, 2007
Developing organs acquire a specific three-dimensional form that ensures their normal function. Cardiac function, for example, depends upon properly shaped chambers that emerge from a primitive heart tube.

Changes of leaf functional traits in karst rocky desertification ecological environment and the driving factors

open access: yesGlobal Ecology and Conservation, 2020
Karst rocky desertification (KRD), a degraded land form, has seriously damaged the balance and stability of the ecosystem. Plant functional traits reflect the response and adaptation of plants to the growth environment. However, little is known about the
