Scripps Institution of Oceanography (SIO) UCSDOrganizer Department of Earth and Planetary SciencesContact Abstract Show full text abstract about The general circulation of the ocean is forced by surface fl...» The general circulation of the ocean is forced by surface fluxes of momentum, heat, and freshwater at basin scales. The kinetic and available potential energy sources associated with these external forces drive a circulation which exhibits flow features that vary on a wide range of spatial and temporal scales. Understanding how the different forcing mechanisms lead to the observed large-scale ocean circulation patterns and to what degree do the various smaller scale processes modify them have been long standing problems for oceanographers.
A large fraction of the kinetic energy in the ocean is stored in the mesoscale eddy field. This `balanced' eddy field is expected, according to geostrophic turbulence theory, to transfer energy to larger scales. In order for the general circulation to remain approximately steady, sub-mesoscale instabilities leading to `loss of balance' (LOB) have been hypothesized to take place so that the eddy kinetic energy (EKE) may be transferred to small scales where it can be dissipated.
We examine the kinetic energy pathways in fully resolved direct numerical simulations of flow in a flat-bottomed re-entrant channel, a configuration that resembles the Antarctic Circumpolar Current. The flow is allowed to reach a statistical steady state at which point it exhibits both a forward and an inverse energy cascade. We show that EKE is dissipated preferentially at small scales near the surface via sub-mesoscale instabilities associated with LOB and a forward energy cascade rather than by bottom drag after an inverse energy cascade. These results highlight the importance of sub-mesoscales dynamics to the general circulation of the oceans.

Soft Matter and BiomaterialsContact Details Show full text description of Membranes of intracellular organelles and transport intermed...» Membranes of intracellular organelles and transport intermediates acquire shapes with large curvatures and complex morphologies, and undergo persistent remodeling by fission and fusion. We suggest a unifying mechanistic framework for understanding how specialized peripheral membrane proteins control the intracellular membrane curvature and dynamics, and address the effects of several specific proteins. Our consideration is based on two major mechanisms by which proteins shape membranes: shallow insertion into the membrane matrix of amphipathic or hydrophobic protein domains, and membrane attachment to the strongly curved and rigid faces of hydrophilic protein scaffolds.
We considering the scaffolding mechanism, by model computationally the shaping of endoplasmic reticulum (ER ) membranes by oligomers of reticulon and DP1/Yop1 family proteins. We demonstrate that membrane molding by these proteins into nearly half-cylindrical shapes underlies generation of the whole plethora of complex morphologies observed to date in ER of different cells, which include ER tubules, sheets, inter-tubular three-way junctions, inter-sheet helicoidal connections and sheet fenestrations.

Students & Postdocs SeminarAbstract Show full text abstract about Grid cell responses develop gradually after eye opening, but...» Grid cell responses develop gradually after eye opening, but little is known about the rules that govern the process. In the first part of the talk, I will present a biologically plausible model for the experience-dependent formation of a grid cell network, one that, among other things, leads to a mature network that can path-integrate velocity inputs, and recapitulates the abrupt transition to stable patterned responses as seen in experiment. The phenomenology of grid cell population activity has rapidly advanced, but, with disparate competing possibilities, the circuit mechanisms underlying grid cell activity remain almost entirely unresolved. In the second part of the talk, I will propose a strategy that combines existing experimental techniques in a way that promises to bring the mechanistic underpinnings of grid cells in sharper focus. The strategy is based on the theoretical insight that small global perturbations of circuit activity will result in characteristic quantal shifts in the spatial tuning relationships between cells, which should be observable from multi- single unit recordings of a small subsample of the population. I will show how this technique allows the experimenter to discriminate between conceptually distinct mechanisms that are currently undifferentiated by experiment. -

Our lack of knowledge on this fundamental question results from a technological gap – the difficulty to track animals over long periods while monitoring their behavior; and from a conceptual gap – how to identify animals’ decision-points outdoors? We apply innovative on-board miniature sensors, to study decision making in wild bats, focusing on one of the most fundamental contexts of decision making – foraging for food. We are interested in how different sources of information, e.g., social information and sensory information, are integrated when making foraging decisions. -
