Photon region and shadow of a rotating 5D black string

European Physical Journal C: Particles and Fields, 2023
To explore the possible clues for the extra dimension from the Event Horizon Telescope (EHT) observations, we study the shadow of the rotating 5D black string in General Relativity (GR).

Bilocal Dynamics for Self-Avoiding Walks [PDF]

, 1999
We introduce several bilocal algorithms for lattice self-avoiding walks that provide reasonable models for the physical kinetics of polymers in the absence of hydrodynamic effects.

Localized inhibition of protein phosphatase 1 by NUAK1 promotes spliceosome activity and reveals a MYC-sensitive feedback control of transcription. [PDF]

, 2020
Deregulated expression of MYC induces a dependence on the NUAK1 kinase, but the molecular mechanisms underlying this dependence have not been fully clarified.

Black holes with scalar hair in light of the Event Horizon Telescope

, 2020
Searching for violations of the no-hair theorem (NHT) is a powerful way to test gravity, and more generally fundamental physics, particularly with regards to the existence of additional scalar fields.

Direct imaging rapidly-rotating non-Kerr black holes [PDF]

, 2012
Recently, two of us have argued that non-Kerr black holes in gravity theories different from General Relativity may have a topologically non-trivial event horizon.

Fermi Surface, Surface States, and Surface Reconstruction in Sr2RuO4

, 2000
The electronic structure of Sr2RuO4 is investigated by high angular resolution ARPES at several incident photon energies. We address the controversial issues of the Fermi surface (FS) topology and of the van Hove singularity at the M point, showing that ...

Bessel beam illumination reduces random and systematic errors in quantitative functional studies using light-sheet microscopy [PDF]

, 2018
Light-sheet microscopy (LSM), in combination with intrinsically transparent zebrafish larvae, is a choice method to observe brain function with high frame rates at cellular resolution.

Evidence for crossed Andreev reflection in superconductor-ferromagnet hybrid structures

, 2004
We have measured the non-local resistance of aluminum-iron spin-valve structures fabricated by e-beam lithography and shadow evaporation. The sample geometry consists of an aluminum bar with two or more ferromagnetic wires forming point contacts to the ...
