Reply to R.L. Bowen et al, M. Froehner et al, J.L. Leow et al, and C. Brady et al.

Regarding our article on the association of androgen deprivation therapy (ADT) with increased Alzheimer’s disease risk, Bowen et al, Froehner and Wirth, Leow et al, and Brady et al highlight a number of significant considerations that will prove important in the design of future studies that investigate the association of ADT and Alzheimer’s disease. We agree with Bowen et al and Leow et al tha...

Topology, Crystallized (Experiments): P. Dziawa et al., arXiv:1206.1705; S.-Y. Xu et al., arXiv:1206.2088

A key difference between quantum Hall phases induced by a magnetic field and topological insulator phases induced by spin-orbit coupling is that the latter depend crucially on a symmetry, time reversal. The action of time-reversal symmetry on electrons leads to a new kind of topological invariant in twodimensional systems [1] that takes only two possible values: if this “Z2 invariant” is even, ...

The frequency analysis of the cochlea – a review of Nobili et al (1998) and Ruggero et al (1992)

Hearing processes seems to divide into three main categories: the caption and transformation of physical sound waves, the transduction of the physical waves into neural patterns and the transformation of these neural patterns into an useful mirror of the physical world. It was thought that the processes of distortion of the physical wave sound, either to enhance the detection of sound origin, e...
