Invasive procedures, such as surgery and acupuncture, are likely better than the others in terms of eliciting placebo analgesia. Understanding how invasive procedures can elicit enhanced placebo responses may provide new insights into mechanisms underlying placebo analgesia. In this essay, it is argued that sensory, cognitive and emotional factors are major determinants of the magnitude of plac...

We give an action for the massless spinning particle in pseudoclassical mechanics by using grassmann variables. The constructed action is invariant under τ -reparametrizations, local SUSY and O(N) transformations. After quantization, for the special case N = 2, we get an action which describes the spin 0, 1 and topological sectors of the massless DKP theory.

Symmetries of a partial Latin square are primarily determined by its autotopism group. Analogously to the case of Latin squares, given an isotopism Θ, the cardinality of the set PLSΘ of partial Latin squares which are invariant under Θ only depends on the conjugacy class of the latter, or, equivalently, on its cycle structure. In the current paper, the cycle structures of the set of autotopisms...

In the article, the influencing factors of the high-voltage transmission line running were analyzed, the important meanings of the real-time online monitoring of the line contact point aging for guaranteeing the safe and stable running of the lines were pointed out, the theoretical reference and the project selection of the high-voltage transmission line temperature monitoring were discussed, a...

I am the head mentor of PRIMES. From time to time one of our mentors tells me that their project is stuck. I then meet with the mentor and their student to brainstorm possible alternative directions. When students suggest their own direction they are more passionate about it and the project gets unstuck. Sometimes a new direction points away from the original question. But after resolving the n...
