Centrifugal Barrier and Super-Keplerian Rotation in Protostellar Disk Formation [PDF]
, 2022 With the advent of ALMA, it is now possible to observationally constrain how disks form around deeply embedded protostars. In particular, the recent ALMA C3H2 line observations of the nearby protostar L1527 have been interpreted as evidence for the so-called "centrifugal barrier," where the protostellar envelope infall is gradually decelerated to a ...

Delivery of exogenous mitochondria via centrifugation enhances cellular metabolic function
Scientific Reports, 2018 Mitochondria are essential organelles involved in the maintenance of cell growth and function, and have been investigated as therapeutic targets in various diseases. Recent studies have demonstrated that direct mitochondrial transfer can restore cellular

The influence of quantum field fluctuations on chaotic dynamics of Yang-Mills system II. The role of the centrifugal term [PDF]
J.Nonlin.Math.Phys.11:289-293,2004, 2005 We have considered SU(2)xU(1) gauge field theory describing electroweak interactions. We have demonstrated that centrifugal term in model Hamiltonian increases the region of regular dynamics of Yang-Mills and Higgs fields system at low densities of energy.

Waves in the gas centrifuge: asymptotic theory and similarities with the atmosphere [PDF]
arXiv, 2021 We study the stratified gas in a rapidly rotating centrifuge as a model for the Earth's atmosphere. Based on methods of perturbation theory, it is shown that in certain regimes, internal waves in the gas centrifuge have the same dispersion relation to leading order as their atmospheric siblings.

Lab-in-a-Tube: A portable imaging spectrophotometer for cost-effective, high-throughput, and label-free analysis of centrifugation processes [PDF]
arXiv, 2023 Centrifuges serve as essential instruments in modern experimental sciences, facilitating a wide range of routine sample processing tasks that necessitate material sedimentation. However, the study for real time observation of the dynamical process during centrifugation has remained elusive.
