DOI: 10.1002/hipo.22994
Abstract: Scale‐invariant timing has been observed in a wide range of behavioral experiments. The firing properties of recently described time cells provide a possible neural substrate for scale‐invariant behavior. Earlier neural circuit models do not produce… read more here.

DOI: 10.1007/s41109-021-00443-x
Abstract: We propose a scale-invariant derivative of the h- index as “ h -dimension”, which is analogous to the fractal dimension of the h- index for institutional performance analysis. The design of h- dimension comes from… read more here.

DOI: 10.1016/j.neucom.2021.01.112
Abstract: Crowd counting is an important vision task, which faces challenges on continuous scale variation within a given scene and huge density shift both within and across images. These challenges are typically addressed using multi-column structures… read more here.

DOI: 10.1016/j.neuroimage.2021.118425
Abstract: Cascading high-amplitude bursts in neural activity, termed avalanches, are thought to provide insight into the complex spatially distributed interactions in neural systems. In human neuroimaging, for example, avalanches occurring during resting-state show scale-invariant dynamics, supporting… read more here.

DOI: 10.1038/s41567-020-1028-0
Abstract: In RuCl 3 , inelastic neutron scattering and Raman spectroscopy reveal a continuum of non-spin-wave excitations that persists to high temperature, suggesting the presence of a spin liquid state on a honeycomb lattice. In the… read more here.

DOI: 10.1080/02664763.2020.1834516
Abstract: For high-dimensional two-sample Behrens–Fisher problems, several non-scale-invariant and scale-invariant tests have been proposed. Most of them impose strong assumptions on the underlying group cov... read more here.

DOI: 10.1103/physreva.101.023608
Abstract: We theoretically study the scale-invariant relaxation dynamics in segregating two-component Bose-Einstein condensates with large particle-number imbalance, and uncover that random walk of droplet for the minor component plays a fundamental role in the relaxation process.… read more here.

Abstract: We study a paradigmatic model in field theory where a global $U(1)$ and scale symmetries are jointly and spontaneously broken. At zero density the model has a non-compact flat direction, which at finite density needs… read more here.
