Directed mean curvature flow in noisy environment

We consider the directed mean curvature flow on the plane in a weak Gaussian random environment. We prove that, when started from a sufficiently flat initial condition, a rescaled and recentred solution converges to the Cole-Hopf solution of the KPZ equati ...

DISCO: Distilling Counterfactuals with Large Language Models

Antoine Bosselut, Zeming Chen, Qiyue Gao

Models trained with counterfactually augmented data learn representations of the causal structure of tasks, enabling robust generalization. However, high-quality counterfactual data is scarce for most tasks and not easily generated at scale. When crowdsour ...

Classical soft graviton theorem rewritten

Biswajit Sahoo

Classical soft graviton theorem gives the gravitational wave-form at future null infinity at late retarded time u for a general classical scattering. The large u expansion has three known universal terms: the constant term, the term proportional to 1/u and ...

Raman spectroscopy and lattice dynamics calculations of tetragonally-structured single crystal zinc phosphide (Zn3P2) nanowires

Anna Fontcuberta i Morral, Elias Zsolt Stutz, Jean-Baptiste Leran, Mahdi Zamani, Simon Robert Escobar Steinvall, Rajrupa Paul, Mirjana Dimitrievska

Earth-abundant and low-cost semiconductors, such as zinc phosphide (Zn3P2), are promising candidates for the next generation photovoltaic applications. However, synthesis on commercially available substrates, which favors the formation of defects, and cont ...

Correlation vs. Causality in Other-Triggered Upward Lightning in Tower Flashes

Farhad Rachidi-Haeri, Marcos Rubinstein, Aleksandr Smorgonskii

Upward lightning flashes from towers are sometimes preceded by other lightning activity in the vicinity of the tower. This observation has led to a classification of upward tower lightning into self-initiated, which are not preceded by nearby lightning act ...

Nowhere and Everywhere: The Causal Origin of Voluntary Action

Aaron Schurger

The idea that intentions make the difference between voluntary and non-voluntary behaviors is simple and intuitive. At the same time, we lack an understanding of how voluntary actions actually come about, and the unquestioned appeal to intentions as discre ...

Semiclassical S-matrix for black holes

Sergey Sibiryakov

We propose a semiclassical method to calculate S-matrix elements for two-stage gravitational transitions involving matter collapse into a black hole and evaporation of the latter. The method consistently incorporates back-reaction of the collapsing and emi ...

Stochastic MPC framework for controlling the average constraint violation

Colin Neil Jones, Milan Korda

This paper considers linear discrete-time systems with additive, bounded, disturbances subject to hard control input bounds and a stochastic constraint on the amount of state-constraint violation averaged over time. The amount of violations is quantified b ...

Horava gravity versus thermodynamics: The black hole case

Sergey Sibiryakov, Diego Blas Temino

Under broad assumptions, breaking of Lorentz invariance in gravitational theories leads to tension with unitarity because it allows for processes that apparently violate the second law of thermodynamics. The crucial ingredient of this argument is the exist ...

Géo-simulation des coûts généralisés de déplacement en transports privés et publics - Automatisation du paramétrage spatio-temporel

Nicolas Lachance-Bernard

Cet article présente une méthodologie pour automatiser la spécification des réseaux de transport adaptés pour la géo-simulation d'itinéraires multimodaux avec TransCAD afin d'évaluer les coûts généralisés de déplacements individuels en milieu urbain. Trois ...

A century-old debate on protein aggregation and neurodegeneration enters the clinic

Hilal Lashuel

The correlation between neurodegenerative disease and protein aggregation in the brain has long been recognized, but a causal relationship has not been unequivocally established, in part because a discrete pathogenic aggregate has not been identified. The ...

The role of the radial electric field for the transition to high confinement regimes

Duccio Testa

The radial electric field E-r(x, t), and particularly its gradient, has been invoked by various theories and empirical models as a crucial parameter 'per se' for determining the transition to high confinement regimes, such as the onset of an internal trans ...

Approche systémique et participative du diagnostic urbain : processus de représentation cognitive du système urbain en vue de l'élaboration d'indicateurs géographiques

Gilles Desthieux

Social, economic and environmental phenomena as well as the presence of groups of stakeholders with diverging and contradictory interests highlight the complexity of urban projects. Traditional instruments of urban management are seldom adapted to these ch ...

From diffusion MRI to brain connectomics

Patric Hagmann

The success of diffusion MRI is deeply rooted in the fact that during their micrometric random displacements water molecules explore tissue microstructure. Hence by labeling magnetically spins of displaced water, diffusion MRI provides us with exquisite in ...
