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

This chapter presents the results of a quantitative longitudinal study that examines the assessment of the professional digital competence of pre-service primary school teachers. The study explores the question of how an...

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...

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...

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...
Estimating the association between blood pressure variability and cardiovascular disease
The association between visit-to-visit systolic blood pressure variability and cardiovascular events has recently received a lot of attention in the cardiovascular literature. But, blood pressure variability is usually estimated...

Universal prethermal dynamics of Bose gases quenched to unitarity.
Christoph Eigen, Jake AP Glidden, Raphael Lopes, Eric A Cornell, Robert P Smith, Zoran Hadzibabic
Nov 29, 2018
Understanding strongly correlated phases of matter, such as the quark-gluon plasma and neutron stars, and in particular the dynamics of such systems, for example, following a Hamiltonian quench (a sudden change in some...
Locomotion of Self-Excited Vibrating and Rotating Objects in Granular Environments
Many reptiles, known as ‘sand swimmers’, adapt to their specific environments by vibrating or rotating their body. To understand these type of interactions of active objects with granular media, we study a simplified...
Light-induced self-assembly of active rectification devices.
Self-propelled colloidal objects, such as motile bacteria or synthetic microswimmers, have microscopically irreversible individual dynamics-a feature they share with all living systems. The incoherent behavior of individual...
