Bounding steady-state availability models with group repair and phase type repair distributions [PDF]

Performance Evaluation, 1999
We propose an algorithm to obtain bounds for the steady-state availability using Markov models in which only a small portion of the state space is generated. The algorithm is applicable to models with group repair and phase type repair distributions and involves the solution of only four linear systems of the size of the generated state space ...

Inhibition of aberrant Hif1α activation delays intervertebral disc degeneration in adult mice

Bone Research, 2022
The intervertebral disc (IVD) is the largest avascular tissue. Hypoxia-inducible factors (HIFs) play essential roles in regulating cellular adaptation in the IVD under physiological conditions. Disc degeneration disease (DDD) is one of the leading causes
