Kavli Affiliate: Rafael Yuste | Authors: Justin Lines and Rafael Yuste | Summary: Neuronal ensembles, defined as groups of coactive neurons, dominate cortical activity and are causally related to perceptual states and behavior. Interestingly, ensembles occur spontaneously in the absence of sensory stimulation. To better understand the function of ensembles in spontaneous activity, we explored […]
Kavli Affiliate: Paul W. Sternberg | Summary:Bacteria can swim upstream due to hydrodynamic interactions with the fluid flow in a narrow tube, and pose a clinical threat of urinary tract infection to patients implanted with catheters. Coatings and structured surfaces have been proposed as a way to suppress bacterial contamination in catheters. However, there is […]

Kavli Affiliate: Mark Ellisman | Authors: Sumin Kim, Sebastien Phan, Thomas R Shaw, Mark H Ellisman, Sarah L Veatch, Sami J Barmada, Samuel S Pappas and William T Dauer | Summary: Nuclear pore complexes (NPCs) regulate information transfer between the nucleus and cytoplasm. NPC defects are linked to several neurological diseases, but the processes governing […]
Kavli Affiliate: Nicole A. Benedek | Summary:We use theory and first-principles calculations to explore mechanisms for control of the translational and point group symmetries of crystals in ultrafast optical experiments. We focus in particular on mechanisms that exploit anharmonic (biquadratic) lattice couplings between a driven infrared-active phonon mode and other modes at arbitrary wave vector, […]

Kavli Affiliate: Nergis Mavalvala | Summary:The observables of a noisy quantum system can be estimated by appropriately filtering the records of their continuous measurement. Such filtering is relevant for state estimation and measurement-based quantum feedback control. It is therefore imperative that the observables estimated through a causal filter satisfy the Heisenberg uncertainty principle. In the […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Kun-Peng Chen, Morgan Le Delliou, , | Summary: In principle, the local cosmic void can be simply modeled by the spherically symmetric Lemaitre-Tolman-Bondi (LTB) metric. In practice, the real local cosmic void is probably not spherically symmetric. In this paper, to reconstruct a more realistic […]
