Microgravity induces overconfidence in perceptual decision-making

Leyla Loued-Khenissi, Davide Scaramuzza, Christian Pfeiffer

Does gravity affect decision-making? This question comes into sharp focus as plans for interplanetary human space missions solidify. In the framework of Bayesian brain theories, gravity encapsulates a strong prior, anchoring agents to a reference frame via ...

Linear and nonlinear excitation of TAE modes by external electromagnetic perturbations using ORB5

Laurent Villard, Emmanuel Lanti, Alberto Bottino, Mohsen Sadr

The excitation of toroidicity-induced Alfven eigenmodes (TAEs) using prescribed external electromagnetic perturbations (hereafter 'antenna') acting on a confined toroidal plasma, as well as its nonlinear couplings to other modes in the system, is studied. ...

Frontiers of (Pareto) Optimal and Sustainable Water Management for Hydropower and Ecology

David Andrew Barry, Paolo Perona, Amin Niayifar, Pierre Razurel

River regulation alters the natural flow regime of streams with consequent impacts on terrestrial and aquatic habitats of the riparian zone. The severity of such impacts can be modulated by changing the redistribution rules at water intakes and reservoirs. ...

Two-Step Thermal Annealing: An Effective Route for 15 % Efficient Quasi-2D Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Giulia Grancini, Valentin Ianis Emmanuel Queloz, Albertus Adrian Sutanto, Giorgio Schileo, Valentino Romano

Low-dimensional perovskites (LDP) are nowadays recognized as promising materials for the realization of highly performing photovoltaic cells. However, issues related to film morphology, composition, crystal quality and material homogeneity limit the device ...

Mixed scalar-current bootstrap in three dimensions

Alessandro Vichi, Marten Jan Reehorst

We study the mixed system of correlation functions involving a scalar field charged under a global U(1) symmetry and the associated conserved spin-1 current J(mu). Using numerical bootstrap techniques we obtain bounds on new observables not accessible in t ...

Micellization behavior of bile salt with pluronic (F-127) and synthesis of silver nanoparticles in a mixed system

Mohammad Khaja Nazeeruddin

The sequestrant is a substance used to cure bile salt diarrhea. They bind to bile salts by hydrophobic and electrostatic forces to stop them from contact with colon mucosa. The block copolymer could be used as bile salt binding agents. Herein, the physicoc ...

Boltzmann Transport in Nanostructures as a Friction Effect

Nicola Marzari, Andrea Cepellotti

Surface scattering is the key limiting factor to thermal transport in dielectric crystals as the length scales are reduced or when temperature is lowered. To explain this phenomenon, it is commonly assumed that the mean free paths of heat carriers are boun ...

Non-proportional Repartition Rules Optimize Environmental Flows and Energy Production

Paolo Perona, Benoît Crouzy, Lorenzo Gorla, Pierre Razurel

In order to meet the growing demand for energy, the development of hydropower leads to an increase of the river exploitation by human activities. Thereby, water management has become a major issue in the energy transition. A better definition of the flow r ...

Particle-size and -density segregation in granular free-surface flows

Christophe Ancey

When a mixture of particles, which differ in both their size and their density, avalanches downslope, the grains can either segregate into layers or remain mixed, dependent on the balance between particle-size and particle-density segregation. In this pape ...

Quasi-static cyclic tests of two mixed reinforced concrete–unreinforced masonry wall structures

Katrin Beyer, Alessandro Paparo

In several seismic countries, residential buildings are constructed using both reinforced concrete (RC) and unreinforced masonry (URM) walls. Despite their popularity, there is a general lack of knowledge concerning the seismic behaviour of such mixed syst ...
