Drs Thomas and Taylor-Robinson comment

Glossary to terms used in the writings and translations of Thomas Taylor

The attentive power of the soul. This power investigates and perceives whatever is transacted in man; and says, I understand, I think, I opine, I am angry, I desire. This attentive part of the soul, also, passes through all the rational, irrational, and vegetable or physical powers. In short, this power is the one of the soul, which follows all the other powers and energizes together with them....

Comment on "Helical magnetorotational instability in magnetized Taylor-Couette flow".

Liu [Phys. Rev. E 74, 056302 (2006)] have presented a WKB analysis of the helical magnetorotational instability (HMRI), and claim that it does not exist for Keplerian rotation profiles. We show that, if radial boundary conditions are included, the HMRI can exist even for rotation profiles as flat as Keplerian, provided only that at least one of the boundaries is sufficiently conducting.

Dynamics of Step Length Adjustment During Running: A Comment on Patla, Robinson, Samways, and Armstrong (1989)

Warren, Young, and Lee (1986) found that treadmill runners control step length by regulating vertical impulse, which could be modulated by the optical time-to-contact variable tau. In contrast, Patla, Robinson, Samways, and Armstrong (1989) report a 40% contribution of horizontal impulse in overground running and a control strategy that depends on the timing of target cuing, undermining the tau...

Comment on ‘a Decomposition of Schur Functions and an Analogue of the Robinson-schensted-knuth Algorithm’

We exhibit a weight-preserving bijection between semi-standard Young tableaux and semi-skyline augmented fillings to provide a combinatorial proof that the Schur functions decompose into nonsymmetric functions indexed by compositions. The insertion procedure involved in the proof leads to an analogue of the Robinson-SchenstedKnuth Algorithm for semi-skyline augmented fillings. This procedure co...
