Dendritic spine geometry and spine apparatus organization govern the spatiotemporal dynamics of calcium. [PDF]
, 2019 Dendritic spines are small subcompartments that protrude from the dendrites of neurons and are important for signaling activity and synaptic communication. These subcompartments have been characterized to have different shapes.

Magnetic reconnection solutions in the presence of multiple nulls [PDF]
, 1999 It is known that exact analytic solutions can be constructed for incompressible magnetic reconnection in three space dimensions. In the case of an isolated X-point null, there are two types of reconnection solutions, namely, “spine” and “fan” models ...

Topological spines of 4-manifolds [PDF]
Algebr. Geom. Topol. 20 (2020) 3589-3606, 2019 We show that infinitely many of the simply connected 4-manifolds constructed by Levine and Lidman that do not admit PL spines actually admit topological spines.

Active adjustment of the cervical spine during pitch production compensates for shape: The ArtiVarK study [PDF]
, 2019 The anterior lordosis of the cervical spine is thought to contribute to pitch (fo) production by influencing cricoid rotation as a function of larynx height. This study examines the matter of inter-individual variation in cervical spine shape and whether

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose The purpose of the present study was to evaluate the impact of bone relative electron density (rED) assignment on radiotherapy planning for the abdominal region. Methods Twenty patients who received abdominal radiotherapy using MR‐Linac and underwent magnetic resonance imaging (MRI) and computed tomography (CT) simulation were analyzed.
