Generalization Ability of Deep Learning Algorithms Trained Using SEM Data for Objects Classification
Radio Science, Volume 57, Issue 12, December 2022., 2022 Abstract This paper proposes an efficient method to determine the material of spherical objects and the location of the receiving antenna relative to the object in bi‐static measurements using supervised learning techniques. From a single observation, we compare classification performances resulting from the application of several classifiers on ...

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The cosmic web for density perturbations of various scales [PDF]
Astron.Astrophys:531,A149,2011, 2010 We follow the evolution of galaxy systems in numerical simulation. Our goal is to understand the role of density perturbations of various scales in the formation and evolution of the cosmic web. We perform numerical simulations with the full power spectrum of perturbations, and with spectrum cut at long wavelengths.

Advanced Science, EarlyView.An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.

Space Weather, Volume 20, Issue 12, December 2022., 2022 Abstract Directional drilling in the oil fields relies particularly on the “on‐fly” measurements of the natural magnetic field (measurements while drilling; MWD); the MWD are eventually used to construct the well path. These measurements are the superposition of the signals from the internal, core and crustal, and external, ionospheric and ...

Scale Transformations, Tree-level Perturbation Theory, and the Cosmological Matter Bispectrum [PDF]
, 2007 Scale transformations have played an extremely successful role in studies of cosmological large-scale structure by relating the non-linear spectrum of cosmological density fluctuations to the linear primordial power at longer wavelengths. Here we generalize this approach to investigate the usefulness of scale transformations for nonlinear higher-order ...

Deflagration to detonation transition by amplification of acoustic waves in type Ia supernovae [PDF]
Astronomy & Astrophysics, Volume 550, id.A105, Feb 2013, 2013 We study a new mechanism for deflagration to detonation transition in thermonuclear supernovae (SNe Ia), based on the formation of shocks by amplification of sound waves in the steep density gradients of white dwarfs envelopes. Given a large enough jump in density a small pressure and velocity perturbation, produced by the turbulent deflagration, turns

Neuron‐Inspired Biomolecular Memcapacitors Formed Using Droplet Interface Bilayer Networks
Advanced Electronic Materials, EarlyView.In this article, a biomolecular model neuron capable of integrating charge is proposed, evaluated, and simulated as a soft neuromorphic device. The device traps charge within microfluidic droplets using lipid membranes and voltage‐activated pores. The trapped charge produces electrowetting of the lipid interfaces, which facilitates multiple memory ...

The measurements of matter density perturbations amplitude from cosmological data [PDF]
Astronomy Letters, 44, 653 (2018), 2018 We compare various physically different measurements of linear matter density perturbation amplitude, $sigma_8$, which are obtained from the observations of CMB anisotropy, galaxy cluster mass function, weak gravitation lensing, matter power spectrum and redshift space distortions.
