Abstract: Hypoxia-inducible factor 1? protein or a detection reagent thereof can be used in depression recurrence diagnosis. It has been demonstrated that the specificity of hypoxia inducible factor 1? protein increases in the serum of patients with depression recurrence after interventions. As such, hypoxia inducible factor 1? protein can be used as a peripheral blood biomarker for the early screening or differentia diagnosis of depression recurrence, and for post-intervention assessment of treatment efficacy of patients with depression.

Abstract: A system and method which tolerates both permanent processor failures and permanent software failures by scheduling a primary and a separate backup on different processors for every real-time process, while further increasing system robustness and reliability, by using primary and backup latest start times to allow primaries or backups to overrun, both before, and after, any permanent processor failure, by effectively utilizing any spare processor capacity including any additional processor capacity created at run-time due to primary or backup underruns, or due to not needing to execute a backup anymore, which significantly increases the chances that a primary or backup may meet its deadline despite permanent hardware failures and permanent software failures, and despite overrunning, while also satisfying additional complex constraints defined on the primaries and backups such as precedence and exclusion relations, in a fault tolerant real-time embedded system.
