Connectivity-Based Parcellation of the Cortical Mantle Using q-Ball Diffusion Imaging

open access: yesInternational Journal of Biomedical Imaging, 2008
This paper exploits the idea that each individual brain region has a specific connection profile to create parcellations of the cortical mantle using MR diffusion imaging. The parcellation is performed in two steps. First, the cortical mantle is split at

Electrification of Fine Particles in Gas-Solids Pipe Flow [Translated]†

open access: yesKONA Powder and Particle Journal, 2014
The electrification of fine particles in a gas-solids pipe flow is investigated theoretically and experimentally. Flowing particles are charged through their collisions with a pipe wall.

Power Corrections and Nonlocal Operators

open access: yes, 1997
We discuss power corrections to infrared safe cross sections and event shapes, and identify a nonperturbative function that governs 1/Q corrections to these quantities.Comment: 4 pages, to appear in Proceedings of the Fifth International Workshop on ...

Resonance supression of high Q particle accelerometer

open access: yes, 2022
The noise floor of high-performance accelerometers is conditioned by the vacuum pressure inside the sensor package. However, less than atmospheric pressure introduces a lower level of damping to the sensor's mechanical structure, resulting in a large static displacement at resonance.

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Funciones de onda en el espacio de fase

open access: yesMomento, 1992
We illustrate the possibility to describe quantum mechanical systems by using wavefunctions ψ (q p) that depend simultaneously on position q. and momentum p of the particles. We obtair.

Barrow entropy effects on thermodynamics and quasi-periodic oscillations around a Frolov black hole

open access: yesNuclear Physics B
This study investigates the geometric structure, particle dynamics, and thermal properties of the non-rotating Frolov black hole. We analyze the black hole geometry and derive the effective potential governing the motion of the test particle, showing the

Dynamic response of one-dimensional interacting fermions

open access: yes, 2006
We evaluate the dynamic structure factor $S(q,\omega)$ of interacting one-dimensional spinless fermions with a nonlinear dispersion relation. The combined effect of the nonlinear dispersion and of the interactions leads to new universal features of $S(q,\

What Do Large Language Models Know About Materials?

open access: yesAdvanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Extended Bose-Hubbard model with incompressible states at fractional numbers

open access: yes, 2005
The Bose-Hubbard model is extended to include nearest and far neighbor interactions and is related to the fractional quantum Hall effect (FQHE). Both models may be studied in optical lattices with quantum gases.
