Measuring Symmetry, Asymmetry and Randomness in Neural Network Connectivity

Cognitive functions are stored in the connectome, the wiring diagram of the brain, which exhibits non-random features, so-called motifs. In this work, we focus on bidirectional, symmetric motifs, i.e. two neurons that project to each other via connections ...

Leptogenesis from first principles in the resonant regime

The lepton asymmetry generated by the out-of-equilibrium decays of heavy Majorana neutrinos with a quasi-degenerate mass spectrum is resonantly enhanced. In this work, we study this scenario within a first-principle approach. The quantum field theoretical ...

Self-Consistent Evolution of Magnetic Fields and Chiral Asymmetry in the Early Universe

Alexey Boyarsky, Oleg Ruchayskiy

We show that the evolution of magnetic fields in a primordial plasma, filled with standard model particles at temperatures T greater than or similar to 10 MeV, is strongly affected by the chiral anomaly-an effect previously neglected. Although reactions, e ...

The Ciliogenic Transcription Factor RFX3 Regulates Early Midline Distribution of Guidepost Neurons Required for Corpus Callosum Development

The corpus callosum (CC) is the major commissure that bridges the cerebral hemispheres. Agenesis of the CC is associated with human ciliopathies, but the origin of this default is unclear. Regulatory Factor X3 (RFX3) is a transcription factor involved in t ...

Feshbach resonances in the water molecule revealed by state-selective spectroscopy

Thomas Rizzo, Pavlo Maksyutenko, Maxim Grechko

We employ triple-resonance vibrational overtone excitation to access quasibound states of water from several fully characterized bound states of the molecule. Comparison of the measured dissociation spectra allows a rigorous assignment of rotational quantu ...

Maximal symmetrization and reduction of fields: Application to wave functions in solid-state nanostructures

Marc-André Dupertuis, Sascha Dalessi

A general formalism for the maximal symmetrization and reduction of fields (MSRFs) is proposed and applied to wave functions in solid-state nanostructures. Its primary target is to provide an essential tool for the study and analysis of the electronic and ...

Plasma Turbulence studied by means of Correlation-ECE in the TEM domain in TCV

Olivier Sauter, Stefano Coda, Timothy Goodman, Jonathan Graves, Laurent Villard, Stephan Brunner, Antoine Pochelon, Yann Camenen, Sébastien Jolliet, Emiliano Fable, Alessandro Bortolon, Alessandro Marinoni, Cornelis Adrianus de Meijere, Mikael Rancic, Francis Voutaz

Plasma Turbulence studied by means of Correlation-ECE in the TEM domain in TCV Electron temperature fluctuations in the TEM domain have been measured in TCV using the correlation-ECE diagnostics [1]. Significant broadband electron temperature fluctuations ...

Galileon as a local modification of gravity

Riccardo Rattazzi

In the Dvali-Gabadadze-Porrati (DGP) model, the "self-accelerating" solution is plagued by a ghost instability, which makes the solution untenable. This fact, as well as all interesting departures from general relativity (GR), are fully captured by a four- ...

Diffraction contrast factor of dislocations: The case of scheelite CaWO4

Jorge Martinez Garcia

Dislocations are known for their peculiar effects on the diffraction profiles. Each given dislocation type, produces specific anisotropic line broadening basically determined by the so-called contrast factor (CF). Owing to the lack of a suitable mathematic ...

Spectroscopy and kinetic studies of electron-hole recombination in CdSe nanoparticles

Awos Al Salman

This thesis presents an experimental study of the energy and time-resolved optical response of chemically prepared CdSe nanoparticles with different sizes, shapes (dots, rods, and tetrapods), and lattice structures (wurtzite and zinc blende). The first par ...
