This new technique has led to great improvements in timing as compared to those in R alone, or R with C and MPI. These improvements include processing and forecasting vectors of size 25,000 in an average time of 6 minutes on the Stampede Supercomputer and 2.5 minutes on the Bridges Supercomputer as compared to previous processing times of 3.5 hours.展开更多

We also develop two term recurrence relations for quantum Bernstein bases and recursive evaluation algorithms for quantum Bezier curves. Our proofs use standard mathematical induction and other elementary techniques.展开更多

We present a case of narcolepsy type 1 in which the cataplexy symptoms were reduced while on suboxone. Aim: This case report aims to note the reduction of cataplexy symptoms with suboxone. Case Presentation: A 39-year-old female patient with narcolepsy type 1 was referred to our pain clinic for management with suboxone. The patient had tried various other medications for the management of narcolepsy. With opioid management, the patient reported reduced cataplexy symptoms. Conclusion: The case illustrates the scientific thought that opioids could increase hypocretin and reduce symptoms in narcolepsy type 1.展开更多
