Group contribution method for thermodynamic analysis of complex metabolic networks

Vassily Hatzimanikatis

Anew, to our knowledge, group contribution method based on the group contribution method of Mavrovouniotis is introduced for estimating the standard Gibbs free energy of formation (Delta(f)G'(degrees)) and reaction (Delta(r)G'(degrees)) in biochemical syst ...

Relationships between dual-task related changes in stride velocity and stride time variability in healthy older adults

Kamiar Aminian, Bijan Najafi

Dual-task related gait changes have been previously reported for healthy older adults, suggesting that gait control requires attention. Compared to balance control, the involvement of attention in the control of the rhythmic stepping mechanism, as reflecte ...

Mobility related physical and functional losses due to aging and disease - a motivation for lower limb exoskeletons

Background Physical and functional losses due to aging and diseases decrease human mobility, independence, and quality of life. This study is aimed at summarizing and quantifying these losses in order to motivate solutions to overcome them with a special f ...

Human walking along a curved path. II. Gait features and EMG patterns

Grégoire Courtine

We recorded basic gait features and associated patterns of leg muscle activity, occurring during continuous body progression when humans walked along a curved trajectory, in order to gain insight into the nervous mechanisms underlying the control of the as ...

Dielectric microcavity in GaN/Si

Nicolas Grandjean

We have demonstrated an original approach for fabricating microcavities in GaN grown on Si. Holes are etched in the Si substrate and highly reflective dielectric mirrors are deposited on both front and back sides. The cavity has been optically characterize ...
