The growth of bulges and discs in relatively HI-rich galaxies: indication from HI scaling relations

Xinkai Chen, Jing Wang, Xu Kong +3

We study the relation between the properties of the bulge/disc components and the HI mass fraction of galaxies. We find that at fixed stellar mass, disc colours are correlated with…

Universal finite size scaling around tricriticality between topologically ordered, SPT, and trivial phases

Ke Wang, T. A. Sedrakyan

A quantum tricritical point is shown to exists in coupled time-reversal symmetry (TRS) broken Majorana chains. The tricriticality separates topologically ordered, symmetry protecte…

If your P value looks too good to be true, it probably is: Communicating reproducibility and variability in cell biology

Samuel J. Lord, Katrina B. Velle, R. Dyche Mullins +1

The cell biology literature is littered with erroneously tiny P values, often the result of evaluating individual cells as independent samples. Because readers use P values and err…

The Spectral Bias of the Deep Image Prior

Prithvijit Chakrabarty, Subhransu Maji

The "deep image prior" proposed by Ulyanov et al. is an intriguing property of neural nets: a convolutional encoder-decoder network can be used as a prior for natural images. The n…
