Concircular trasformation of a quarter symmetric metric connection in an SP-Sasakian manifold [PDF]

International Mathematical Forum, 2013
Summary: In [Tensor, New Ser. 38, 103--108 (1982; Zbl 0504.53015)], \textit{P. Stavre} defined semi-symmetric S-concircular and S-conharmonic connections and established some results. Anologous to this we define a concircular transformation on quarter symmetric metric connection in an SP-Sasakian manifold.

Pinching Results for Doubly Warped Products' Pointwise Bi-Slant Submanifolds in Locally Conformal Almost Cosymplectic Manifolds with a Quarter-Symmetric Connection

Symmetry
In this research paper, we establish geometric inequalities that characterize the relationship between the squared mean curvature and the warping functions of a doubly warped product pointwise bi-slant submanifold.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.
