Bilateral symmetric dumbbell C1-C2 ganglioneuroma in neurofibromatosis type 1 patient causing spastic quadriparesis

open access: yesJournal of Spinal Surgery, 2018
Introduction: Ganglioneuroma is a very rare tumor and rarely found bilaterally in association with neurofibromatosis patient. Very few cases of dumbbell ganglioneuroma in the cervical region have been reported in the literature.

Total Coloring of Dumbbell Maximal Planar Graphs

open access: yesMathematics, 2022
The Total Coloring Conjecture (TCC) states that every simple graph G is totally (Δ+2)-colorable, where Δ denotes the maximum degree of G. In this paper, we prove that TCC holds for dumbbell maximal planar graphs.

New Phases of Germanene [PDF]

open access: yes, 2014
Germanene, a graphene like single layer structure of Ge, has been shown to be stable and recently grown on Pt and Au substrates. We show that a Ge adatom adsorbed to germanene pushes down the host Ge atom underneath and forms a dumbbell structure.

Tides and Dumbbell Dynamics

open access: yesRegular and Chaotic Dynamics, 2022
We discuss a model describing the effects of tidal dissipation on satellite's orbits. Tidal bulges are described in terms of a dumbbell, coupled to the rotation by a dissipative interaction. The assumptions on this dissipative coupling turns out to be crucial in the evolution of the system.

Virtual Gymnasium: Personalized Weight Perception Interface in Lifting Virtual Objects

open access: yesApplied Sciences, 2022
This paper proposes a pseudo-haptic interface that depicts the virtual weights of dumbbells in a virtual gymnasium. When a user performs a dumbbell biceps curl, he/she fixes the elbow joint as a standard joint and lifts the dumbbell, with its movement ...

Adsorption of Group-IV Elements on Graphene, Silicene, Germanene, Stanene: Dumbbell Formation [PDF]

open access: yes, 2014
Silicene and germanene derivatives constructed from periodic dumbbell units play a crucial role in multilayers of these honeycomb structures. Using first-principles calculations based on density functional theory, here we investigate the dumbbell ...

Modelling of AlAs/GaAs interfacial structures using high-angle annular dark field (HAADF) image simulations [PDF]

open access: yes, 2012
High angle annular dark field (HAADF) image simulations were performed on a series of AlAs/GaAsinterfacial models using the frozen-phonon multislice method. Three general types of models were considered—perfect, vicinal/sawtooth and diffusion. These were
