Natural exosome-like nanovesicles from edible tea flowers suppress metastatic breast cancer via ROS generation and microbiota modulation

open access: yesActa Pharmaceutica Sinica B, 2021
Although several artificial nanotherapeutics have been approved for practical treatment of metastatic breast cancer, their inefficient therapeutic outcomes, serious adverse effects, and high cost of mass production remain crucial challenges.

Search for pair-production of vector-like quarks in lepton+jets final states containing at least one b-tagged jet using the Run 2 data from the ATLAS experiment [PDF]

open access: yesPhysics Letters B
A search is presented for the pair-production of heavy vector-like quarks in the lepton+jets final state using 140 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}= 13$ TeV collected with the ATLAS detector.

Entanglement of exact excited states of Affleck-Kennedy-Lieb-Tasaki models: Exact results, many-body scars, and violation of the strong eigenstate thermalization hypothesis

open access: yesPhysical review B, 2018
We obtain multiple exact results on the entanglement of the exact excited states of nonintegrable models we introduced in Phys. Rev. B 98, 235155 (2018)10.1103/PhysRevB.98.235155.

Disconnected elementary band representations, fragile topology, and Wilson loops as topological indices: An example on the triangular lattice [PDF]

open access: yesPhysical review B, 2018
In this work, we examine the topological phases that can arise in trangular lattices with disconnected elementary band representations. We show that, although these phases may be ``fragile'' with respect to the addition of extra bands, there always exist

Towards a unified study of multiple stressors: divisions and common goals across research disciplines

open access: yesProceedings of the Royal Society B, 2020
Anthropogenic environmental changes, or ‘stressors’, increasingly threaten biodiversity and ecosystem functioning worldwide. Multiple-stressor research is a rapidly expanding field of science that seeks to understand and ultimately predict the ...
