Toroidal-poloidal partitioning of plate motions since 120 MA [PDF]
, 1993 Changes in plate motions and plate configurations during the Cenozoic and Mesozoic have been investigated extensively, but most geodynamical models have concentrated on present-day plate motions.

Adiabatic compression of plasma with purely toroidal rotation [PDF]
, 1989 A variational method is developed to find approximate solutions to the generalized Grad-Shafranov equations for an adiabatic compression of the plasma with toroidal rotation, via the expansion in Fourier series in poloidal angle of the flux surface ...

Ballooning Modes in a Toroidally Rotating Plasma [PDF]
Australian Journal of Physics, 1997 The stability of ideal ballooning modes in the presence of a rigid toroidal rotation is revisited. Two stabilising contributions arising due to rigid toroidal rotation are identified. These stabilising contributions can be particularly significant for present and future generations of low and ultra-low aspect ratio tokamaks.

Zoomable telescope by rotation of toroidal lenses [PDF]
Applied Optics, 2018 A novel type of a continuously zoomable telescope is based on two pairs of adjacent toroidal lenses ("saddle lenses") in combination with standard optical components. Its variable magnification is adjusted by a mere rotation of the four saddle lenses around the optical axis.

Nuclear Fusion, 2023 The effects of different working gases on the transition from linear ohmic confinement (LOC) regime to saturated ohmic confinement (SOC) regime and its relation to the intrinsic toroidal rotation reversal phenomenon were explored in the TCV tokamak.

Transport-Driven Toroidal Rotation in the Tokamak Edge [PDF]
Physical Review Letters, 2012 The interaction of passing-ion drift orbits with spatially-inhomogeneous but purely diffusive radial transport is demonstrated to cause spontaneous toroidal spin-up to experimentally-relevant values in the tokamak edge. Physically, major-radial orbit shifts cause orbit-averaged diffusivities to depend on parallel velocity, including its sign, leading ...

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2022 Since the helical surface of the toroidal worm is a complex space surface with variable-lead, the design method and high-efficiency machining method for the consistency rough machining allowance of the toroidal worm are not perfect, which is not ...

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron
Angewandte Chemie, EarlyView.Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage
