A new analysis approach for T-2 relaxometry myelin water quantification: Orthogonal Matching Pursuit

Purpose: In vivo myelin quantification can provide valuable noninvasive information on neuronal maturation and development, as well as insights into neurological disorders. Multiexponential analysis of multiecho T-2 relaxation is a powerful and widely appl ...

Maximum-energy records in glassy energy landscapes

Marco Baity-Jesi, Riccardo Ravasio

We study the evolution of the maximum energy E-max(t) reached between time 0 and time t in the dynamics of simple models with glassy energy landscapes, after an instant quench from infinite temperature to a target temperature T. Through a detailed descript ...

Comparing dynamics: deep neural networks versus glassy systems

Matthieu Wyart, Mario Geiger, Marco Baity-Jesi, Stefano Spigler, Levent Dogus Sagun

We analyze numerically the training dynamics of deep neural networks (DNN) by using methods developed in statistical physics of glassy systems. The two main issues we address are (1) the complexity of the loss landscape and of the dynamics within it, and ( ...

Virus lasers for biological detection

Gabriel Aeppli

The selective amplification of DNA in the polymerase chain reaction is used to exponentially increase the signal in molecular diagnostics for nucleic acids, but there are no analogous techniques for signal enhancement in clinical tests for proteins or cell ...

Comparing Dynamics: Deep Neural Networks versus Glassy Systems

Mario Geiger, Marco Baity-Jesi, Rainer Wesche, Stefano Spigler, Levent Dogus Sagun

We analyze numerically the training dynamics of deep neural networks (DNN) by using methods developed in statistical physics of glassy systems. The two main issues we address are the complexity of the loss-landscape and of the dynamics within it, and to wh ...

Hydromechanical Aspects of CO2 Breakthrough into Clay-rich Caprock

Lyesse Laloui, Victor Vilarrasa Riano, Roman Makhnenko, Danila Mylnikov

Caprock formations are intended to prevent upwards carbon dioxide (CO2) migration to the surface during CO2 geological storage. Caprock interaction with CO2, as well as its potential consequences, requires to be predicted, and thus, need to be studied expe ...

The resumption of concrete use in modern times. Key episodes from archival sources and technical literature

Salvatore Aprea

The modern use of concrete developed in the eighteenth and nineteenth centuries from the interest in archaeology, the observation of some vernacular building techniques and some construction-site practices that had survived locally from the times of ancien ...

New hydraulic gallery to improve operation conditions at the Emosson hydro scheme

Azin Amini, Nima Nilipour

A new hydraulic gallery was constructed to increase operational resilience and mitigate risks of Emosson hydropower scheme in the Swiss-French Alps. One of the main constraints of the operation is to avoid the overflow of the so called "Corbes" surge chimn ...

Liquid CO2 processing of solid polylactide foam precursors

John Christopher Plummer, Yonghoon Yoon

Diffusion of CO2 in polylactide was modelled by assuming the diffusion coefficient to depend on CO2 concentration, c, according to D[c]=D[0]exp[Ac], where D[0] and A are empirical constants, with the aim of optimizing impregnation of nominally amorphous an ...

Harnessing the damping properties of materials for high-speed atomic force microscopy

Jürgen Brugger, Georg Fantner, Adrian Pascal Nievergelt, Blake William Erickson, Jonathan David Adams, Jonas Grossenbacher

The success of high-speed atomic force microscopy in imaging molecular motors1, enzymes2 and microbes3 in liquid environments suggests that the technique could be of significant value in a variety of areas of nanotechnology. However, the majority of atomic ...
