E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure
Advanced Materials, EarlyView.The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Human Movement Science, 2005
Consider the process of raising and lowering the arm in the sagittal plane. Different parts of different muscles operate over different sectors of the angular range. How and why does the nervous system implement this differential muscle activation according to joint angle?

Neurosurgery Clinics of North America, 2011
Functional magnetic resonance imaging (fMRI) enhances the understanding of neuroanatomy and functions of the brain and is becoming an accepted brain-mapping tool for clinicians, researchers, and basic scientists alike. A noninvasive procedure with no known risks, fMRI has an ever-growing list of clinical applications, including presurgical mapping of ...

MAPs and motors in insect ovaries
Journal of Cell Science, 1991ABSTRACT MAPs and microtubule motor proteins from the massive microtubule translocation complexes within the ovaries of hemipteran insects have been identified and characterized. Both classes of proteins have been compared with those of other systems, and the function of both in the insect ovaries is speculated upon.

Chaos control by using Motor Maps
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2002In this paper a new method for chaos control is proposed, consisting of an unsupervised neural network, namely a Motor Map. In particular a feedback entrainment scheme is adopted: a chaotic system with a given parameter set generates the reference trajectory for another chaotic system with different parameters to be controlled: the Motor Map is ...

Microtubules, MAPs, and motor patterns
2015Cells have an amazing ability to self-organize and rearrange their interiors. Such morphology changes are essential to cell development, division, and motility. The core of a cell's internal organization lies with the cytoskeleton made of both microtubule and actin filaments with their associated proteins and ATP-utilizing enzymes.

Interaction of kinesin motors, microtubules, and MAPs
Journal of Muscle Research and Cell Motility, 2005Kinesins are a family of microtubule-dependent motor proteins that carry cargoes such as vesicles, organelles, or protein complexes along microtubules. Here we summarize structural studies of the "conventional" motor protein kinesin-1 and its interactions with microtubules, as determined by X-ray crystallography and cryo-electron microscopy.
