Quantum computing technology may soon deliver revolutionary improvements in algorithmic performance, but it is useful only if computed answers are correct. While hardware-level decoherence errors have garnered significant attention, a less recognized obstacle to correctness is that of human programming errors-"bugs." Techniques familiar to most programmers from the classical domain for avoiding, discovering, and diagnosing bugs do not easily transfer, at scale, to the quantum domain because of its unique characteristics.

The source utilizes converging X-ray collimation along with orthogonal mechanical rotation to distribute surface flux over large area. In this study, this was investigated as a potential solution to fast-falloff limitations expected with kV radiotherapy.

Anatomic variation could account for some of this difficulty. Cadaver dissection and electrophysiological testing were used to characterize deep and superficial fibular sensory nerve supply to the foot.

Objective: To strengthen existing efficacy and safety data, and examine subject satisfaction concerning abobotulinumtoxinA (ABO) treatment for moderate to severe glabellar lines.
Materials And Methods: A 150-day prospective, single-dose, multicenter, randomized, parallel-group, placebo-controlled, double-blind study of 300 subjects treated with ABO (50 Units [U]).
