We reveal a natural algebraic problem whose complexity appears to interpolate between the well-known complexity classes BQP and NP: ⋆ Decide whether a univariate polynomial with exactly m monomial terms has a p-adic rational root. In particular, we show that while (⋆) is doable in quantum randomized polynomial time when m=2 (and no classical randomized polynomial time algorithm is known), (⋆) i...

BACKGROUND While substantial placebo and nocebo effects have been documented in antidepressant clinical trials, physicians' awareness of the nonspecific effects in routine antidepressant treatment remains unclear. The study investigated physicians' beliefs and explanatory models regarding the desired effects and undesired side effects of antidepressants, with specific emphasis on nonspecific ef...

The conclusion of Kooga et al. [1] that ‘‘the nocebo effect of acupuncture is clinically meaningful and the rate of patients with any adverse event may be a more appropriate indicator of the nocebo effect’’ deserves some comments. First, opposing placebo and nocebo is a misconception. Indeed, conditioning and expectations are the main factors triggering a response, whether positive or negative....
