The cell adhesion molecule Sdk1 shapes assembly of a retinal circuit that detects localized edges
eLife, 2021 Nearly 50 different mouse retinal ganglion cell (RGC) types sample the visual scene for distinct features. RGC feature selectivity arises from their synapses with a specific subset of amacrine (AC) and bipolar cell (BC) types, but how RGC dendrites ...

Polarization-controlled anisotropy in hybrid plasmonic nanoparticles
Nanophotonics, 2022 Anisotropy has played a critical role in many material systems, but its controllable creation and modulation have been a long-lasting challenge for the scientific communities. Polarization-addressed anisotropy appears more attractive among all approaches

Two Photon Physics at LEP [PDF]
, 1999 LEP offers an excellent opportunity to measure two photon processes over a large kinematical range and thus study the complex nature of the photon. This article reviews the experimental status of ``Two Photon Physics'' at LEP.

Two-Photon Exclusive Processes in QCD [PDF]
, 2000 Exclusive two-photon reactions such as Compton scattering at large angles, deeply virtual Compton scattering, and hadron production in photon-photon collisions provide important tests of QCD at the amplitude level, particularly as measures of hadron ...

A laser–plasma platform for photon–photon physics: the two photon Breit–Wheeler process
New Journal of Physics, 2021 We describe a laser–plasma platform for photon–photon collision experiments to measure fundamental quantum electrodynamic processes. As an example we describe using this platform to attempt to observe the linear Breit–Wheeler process.

Place Cells in Head-Fixed Mice Navigating a Floating Real-World Environment
Frontiers in Cellular Neuroscience, 2021 The hippocampal place cell system in rodents has provided a major paradigm for the scientific investigation of memory function and dysfunction. Place cells have been observed in area CA1 of the hippocampus of both freely moving animals, and of head-fixed
