Canadian Journal of Physics, 1960 The diffraction of a spherical scalar wave by a hard or soft spheroid is investigated theoretically. First the diffracted field is determined by the geometrical theory of diffraction. Then for comparison the corresponding boundary value problem is solved exactly in terms of a series of products of spheroidal functions. The series involves the "radial"

Axonal spheroids in neurodegeneration
Molecular and Cellular Neuroscience, 2021Axonal spheroids are bubble-like biological features that form on most degenerating axons, yet little is known about their influence on degenerative processes. Their formation and growth has been observed in response to various degenerative triggers such as injury, oxidative stress, inflammatory factors, and neurotoxic molecules.

Characterization of spheroids in hereditary diffuse leukoencephalopathy with axonal spheroids
Journal of the Neurological Sciences, 2015Hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) is a neurodegenerative disease clinically characterized by slowly progressive cognitive decline and motor dysfunction. Neuropathology shows diffuse degeneration in the white matter, with prominent presence of widespread axonal spheroids.

Electromagnetic Eigenfrequencies in a Spheroidal Cavity (Calculation By Spheroidal Eigenvectors)
Journal of Electromagnetic Waves and Applications, 1998Summary: The electromagnetic eigenfrequencies \(f_{nsm}\) in a perfectly conducting spheroidal cavity are determined analytically. The analytical determination is possible in the case of small values of \(h= d/(2a)\), \((h\ll 1)\), where \(d\) is the interfocal distance of the spheroidal cavity and \(2a\) the length of its rotation axis.

Dermatoleukodystrophy With Neuroaxonal Spheroids
Archives of Neurology, 1978A Japanese brother and sister, the progeny of healthy parents, were born with thickened, wrinkled skin and died between the age of 2 and 3 years with a progressive cerebral disease characterized by generalized mental and motor impairment. Postmortem neuropathological studies disclosed a remarkable leukodystrophy in which multiple axonal spheroids were ...

Critical Reviews in Oncology/Hematology, 2000
In contrast to most traditional cell culture systems, spheroids represent a unique opportunity to recapitulate aspects of cell homeostasis and as such better reflect in vivo tumor biology. This review highlights recent spheroid-based studies which have defined a role for intercellular adhesion in dictating cellular fate.

Radiation Studies with Spheroids
1984Our intent in this chapter is to present a review of the methodology currently available for the study of spheroid response(s) to ionizing radiation; it should nonetheless be obvious that the assay techniques are universally applicable to the study of any cytotoxic agent.

Translation and rotation of a porous spheroid in a spheroidal container
Canadian Journal of Physics, 2010The flow problem of an incompressible axisymmetrical quasisteady translation and steady rotation of a porous spheroid in a concentric spheroidal container are studied analytically. The same small departure from a sphere is considered for each spheroidal surface.

Spheroidal wave functions occur in many scientific and engineering contexts, from atomic nuclei to the cosmos-scattering by nonspherical nuclei, wave functions of diatomic molecules, analysis of band-limited random noise, orthogonal frequency division multiplexing, and anisotropy of the cosmic microwave background radiation.
