Analysis of the Movement of Chlamydomonas Flagella: The Function of the Radial-spoke System Is Revealed by Comparison of Wild-type and Mutant Flagella [PDF]
, 1982 The mutation uni-1 gives rise to uniflagellate Chlamydomonas cells which rotate around a fixed point in the microscope field, so that the flagellar bending pattern can be photographed easily .

Cricket antennae shorten when bending (Acheta domesticus L.). [PDF]
, 2014 Insect antennae are important mechanosensory and chemosensory organs. Insect appendages, such as antennae, are encased in a cuticular exoskeleton and are thought to bend only between segments or subsegments where the cuticle is thinner, more flexible, or

Regularized Stokeslet segments [PDF]
, 2018 We present a variation of the method of regularized Stokeslet (MRS) specialized for the case of forces and torques distributed over filaments in three dimensions. The new formulation is based on the exact solution of Stokes equation generated by a linear continuous distribution of regularized forces along a line segment.

Vibration of the Flagellum of the Ant Antennæ [PDF]
Nature, 1949 IN May 1949, a series of photographs of ants of the species Formica rufa, Latr., were taken by Raymond Kleboe of Picture Post, in collaboration with me, and in many of these worker ants were shown. The ants were usually in a posture of defence ; but whether they were defending the nest, attacking prey, or merely hurrying over the surface of the nest or

Effects of Increased Viscosity on the Movements of Some Invertebrate Spermatozoa [PDF]
, 1966 In the wave pattern of a flagellum generating planar undulatory bending waves, bending and unbending are represented by rather abrupt transitions between bent and unbent states (Brokaw & Wright, 1963; Brokaw, 1965). The magnitude of these transitions is

The developmental cell biology of Trypanosoma brucei [PDF]
, 2005 Trypanosoma brucei provides an excellent system for studies of many aspects of cell biology, including cell structure and morphology, organelle positioning, cell division and protein trafficking. However, the trypanosome has a complex life cycle in which

Control of uniflagellar soft robots at low Reynolds number using buckling instability [PDF]
arXiv, 2018 In this paper, we analyze the inverse dynamics and control of a bacteria-inspired uniflagellar robot in a fluid medium at low Reynolds number. Inspired by the mechanism behind the locomotion of flagellated bacteria, we consider a robot comprised of a flagellum -- a flexible helical filament -- attached to a spherical head.

IFT25 is required for the construction of the trypanosome flagellum [PDF]
Journal of Cell Science, 2018 Intraflagellar transport (IFT), the movement of protein complexes responsible for the assembly of cilia and flagella, is remarkably conserved from protists to humans. However, two IFT components (IFT25 and IFT27) are missing from multiple unrelated eukaryotic species.

Swarm behavior of self-propelled rods and swimming flagella [PDF]
, 2010 Systems of self-propelled particles are known for their tendency to aggregate and to display swarm behavior. We investigate two model systems, self-propelled rods interacting via volume exclusion, and sinusoidally-beating flagella embedded in a fluid ...

A short review on the morphology of Trypanosoma cruzi: from 1909 to 1999
Memorias do Instituto Oswaldo Cruz, 1999 The morphology of Trypanosoma cruzi is reviewed since the initial description of Giemsa-stained preparations by Carlos Chagas until the most recent micrographs obtained with freeze-fracture techniques.
