Conserved neural circuit structure across Drosophila larval development revealed by comparative connectomics.
Stephan Gerhard, Ingrid Andrade, Richard D Fetter, Albert Cardona, Casey M Schneider-Mizell
Jan 25, 2018
During postembryonic development, the nervous system must adapt to a growing body. How changes in neuronal structure and connectivity contribute to the maintenance of appropriate circuit function remains unclear. Previously , we...
The unusual problem of upscaling isostaticity theory for granular matter
Raphael Blumenfeld
Jun 06, 2020
Abstract: Isostaticity theory (IT) provides stress field equations for marginally rigid packs of non-cohesive particles, interacting through hard-core forces. Its main advantage over strain-based theories is by closing the...
Educational Robotics in Higher Education for Promoting Pre-Service Primary School Teachers

Presume It Not
Kyle Stanford has recently given substance to the problem of unconceived alternatives, which challenges the reliability of inference to the best explanation (IBE) in remote domains of nature. Conjoined with the view that IBE is...
Affine and topogical structural entropies in granular statistical mechanics
We identify two orthogonal sources of structural entropy in rattler-free granular systems: affine, involving structural changes that only deform the contact network, and topological, corresponding to different topologies of the...
Fundamental structural characteristics of planar granular assemblies
The microstructural organization of a granular system is the most important determinant of its macroscopic behavior. Here we identify the fundamental factors that determine the statistics of such microstructures, using numerical...

Theory-based design of sintered granular composites triples three-phase boundary in fuel cells.
Solid-oxide fuel cells produce electric current from energy released by a spontaneous electrochemical reaction. The efficiency of these devices depends crucially on the microstructure of their electrodes and in particular on the...
Quantum Depletion of a Homogeneous Bose-Einstein Condensate.
Raphael Lopes, Christoph Eigen, Nir Navon, David Clément, Robert P Smith, Zoran Hadzibabic
Jun 13, 2018
We measure the quantum depletion of an interacting homogeneous Bose-Einstein condensate and confirm the 70-year-old theory of Bogoliubov. The observed condensate depletion is reversibly tunable by changing the strength of the...

Dopaminergic Modulation Shapes Sensorimotor Processing in the Drosophila Mushroom Body
Raphael Cohn
Jan 01, 0001
To survive in a complex and dynamic environment, animals must adapt their behavior based on their current needs and prior experiences. This flexibility is often mediated by neuromodulation within neural circuits that link...

Downregulation of exosomal miR-204-5p and miR-632 as a biomarker for FTD
Raphael Schneider, Paul McKeever, TaeHyung Kim, Caroline Graff, John Cornelis van Swieten, Anna Karydas, Adam Boxer, Howie Rosen, Bruce L Miller, Robert Laforce, Daniela Galimberti, Mario Masellis, Barbara Borroni, Zhaolei Zhang, Lorne Zinman, Jonathan Daniel Rohrer, Maria Carmela Tartaglia, Janice Robertson, Genetic FTD Initiative (GENFI)
May 10, 2018
OBJECTIVE: To determine whether exosomal microRNAs (miRNAs) in cerebrospinal fluid (CSF) of patients with frontotemporal dementia (FTD) can serve as diagnostic biomarkers, we assessed miRNA expression in the Genetic...
Support of modified Archimedes' law theory in granular media.
We study the resistance force of cylindrical objects penetrating quasi-statically into granular media experimentally and numerically. Simulations are validated against experiments. In contrast to previous studies, we find in...
Interest group size and legislative lobbying
Maik Schneider
Oct 01, 2014
We develop a model of legislative decision making in which lobbying and public policy are jointly determined. We examine how policy outcomes depend on the sizes of the interest groups. While a larger size typically involves...

First constraint on the neutrino-induced phase shift in the spectrum of baryon acoustic oscillations

Feb 18, 2019
The existence of the cosmic neutrino background is a robust prediction of the hot big bang model. These neutrinos were a dominant component of the energy density in the early universe and, therefore, played an important role in...
Universal Scaling Laws in the Dynamics of a Homogeneous Unitary Bose Gas.
Christoph Eigen, Jake AP Glidden, Raphael Lopes, Nir Navon, Zoran Hadzibabic, Robert P Smith
Jan 17, 2018
We study the dynamics of an initially degenerate homogeneous Bose gas after an interaction quench to the unitary regime at a magnetic Feshbach resonance. As the cloud decays and heats, it exhibits a crossover from degenerate- to...
