Metamorphism and Deformation on Subduction Interfaces: 1. Physical Framework

open access: yesGeochemistry, Geophysics, Geosystems, 2023
A thermal and mechanical framework is presented for analysis of pressure‐temperature (P‐T) data and structural observations from high‐pressure‐low‐temperature (HPLT) terrains. P‐T data from 281 HPLT rocks exhibit two regimes separated at a pressure of ∼1.

Simple Analytical Expression of the Voigt Profile

open access: yesQuantum Reports, 2022
This work examines several analytical evaluations of the Voigt profile, which is a convolution of the Gaussian and Lorentzian profiles, theoretically and numerically. Mathematical derivations are performed concisely to illustrate some closed forms of the

Spectral and cross-spectral densities expressions’ refinement for rail vehicle oscillations [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper, we derive analytical expressions describing spectral and mutual spectral densities of random processes by performing analytical Fourier transform of the corresponding correlation functions.

Analytical Approach of Director Tilting in Nematic Liquid Crystals for Electronically Tunable Devices

open access: yesIEEE Access, 2019
This paper presents an analytical expression that models the tilt angle of directors in a nematic liquid crystal (LC), depending on its elastic properties, its dielectric anisotropy, and the quasi-static electric field applied.

Mean Expression of the X-Chromosome is Associated with Neuronal Density. [PDF]

open access: yes, 2012
peer reviewedBackground: Neurodegenerative diseases are characterized by key features such as loss of neurons, astrocytosis, and microglial activation/proliferation. These changes cause differences in the density of cell types between control and disease

Identification of highly expressed, soluble proteins using an improved, high-throughput pooled ORF expression technology

open access: yesBioTechniques, 2008
This article describes an improved pooled open reading frame (ORF) expression technology (POET) that uses recombinational cloning and solution-based tandem mass spectrometry (MS/MS) to identify ORFs that yield high levels of soluble, purified protein ...

Analytical expression for uncertainty propagation of aerial cooperative navigation

open access: yesAviation, 2021
In this paper, the propagation of uncertainty in a cooperative navigation algorithm (CNA) for a group of flying robots (FRs) is investigated. Each FR is equipped with an inertial measurement unit (IMU) and range-bearing sensors to measure the relative ...
