Morphological Adaptation of River Channels to Vegetation Establishment: A Laboratory Study

open access: yesJournal of Geophysical Research: Earth Surface, 2019
While the scientific community has long recognized that alluvial rivers are the product of interactions between flowing water and bed material transport, it is increasingly evident that vegetation mediates these interactions and influences the stream ...

Quantitative morphology of renal cortical structures during compensatory hypertrophy [PDF]

open access: yes, 1998
The compensatory hypertrophy in different renal cortical structures was studied in rats 10 and 21 days after unilateral nephrectomy (UNX). Quantitative morphological/stereological analysis revealed significant increases in total renal cortical volume ...

Exploring the practical knowledge of eccentric resistance training in high-performance strength and conditioning practitioners [PDF]

open access: yes, 2020
Habitual use of eccentric exercise has been recognised to increase strength and power; however, the current body of knowledge has limited potential to understand the application of such resistance training in athletic populations.

Body size changes in passerine birds introduced to New Zealand from the UK [PDF]

open access: yes, 2013
One feature of global geographic variation in avian body sizes is that they are larger on isolated islands than on continental regions. Therefore, this study aims to assess whether there have been changes in body size following successful establishment ...

Shaping Behavior With Adaptive Morphology [PDF]

open access: yesIEEE Robotics and Automation Letters, 2018
Robots that exploit their embodiment promise to be more robust, energy-efficient, and adaptable. However, the majority of systems designed in this way are only capable of exploiting their embodiment when performing a single task in a single environment.

Range-based techniques for discovering optimality and analyzing scaling relationships in neuromechanical systems [PDF]

open access: yes, 2009
In this paper, a method for decoupling the neuromuscular function of a set of limbs from the role morphology plays in regulating the performance of an activity is introduced.

Drought tolerance of faba bean (Vicia faba L.) can be improved by specific LED light wavelengths

open access: yesPhotosynthetica, 2020
A light wavelength affects both plant photomorphogenesis and stress resistance. In this study, the phenotypic plasticity (growth parameters and cuticular waxes) and physiological adaptation (photosynthetic properties and antioxidant enzyme activities) of
