Approach for the Simulation and Modeling of Flexible Rings:  Application to the α-d-Arabinofuranoside Ring, a Key Constituent of Polysaccharides from Mycobacterium tuberculosis [PDF]

Journal of Chemical Theory and Computation, 2007
A number of lower organisms (bacteria, fungi, and parasites) produce glycoconjugates that contain furanose rings. Of particular interest to our group are cell wall polysaccharides from mycobacteria, including the human pathogen, Mycobacterium tuberculosis, which contain a large number of arabinofuranose resides.

Numerical Study of the Aerodynamics of a Hovering Hummingbird’s Wing with Dynamic Morphing

International Journal of Aerospace Engineering, 2022
To deepen our understanding of the aerodynamics by which hummingbirds use flexible wings to hover efficiently during flapping flight, a three-dimensional wing model with dynamic morphing was developed according to the morphological and kinematic data of ...

An axis-specific mitral annuloplasty ring eliminates mitral regurgitation allowing mitral annular motion in an ovine model

Communications Medicine
Introduction Current mitral annuloplasty rings fail to restrict the anteroposterior distance while allowing dynamic mitral annular changes. We designed and manufactured a mitral annuloplasty ring that demonstrated axis-specific, selective flexibility to ...
