A lipidomics study reveals hepatic lipid signatures associating with deficiency of the LDL receptor in a rat model

open access: yesBiology Open, 2016
The low-density lipoprotein receptor (LDLR) plays a critical role in the liver for the clearance of plasma low-density lipoprotein (LDL). Its deficiency causes hypercholesterolemia in many models.

Assessment of shear effects of RC beams and columns on seismic performance of RC structures [PDF]

open access: yesJournal of Structural and Construction Engineering, 2019
Shear failure plays a significant role in the seismic behavior of reinforced concrete (RC) structures. Generally, nonlinear analysis of the beams and columns in concrete structures is based on the flexural behavior of the members, and shear effects are ...

Estimation of mechanics parameters of rock in consideration of confining pressure using monitoring while drilling data

open access: yesFrontiers in Earth Science, 2023
During the drilling process, high-strength rock can lead to various issues such as drilling suppression, bit wear, and increased operational costs.

Analytic modelling of biotransistors

open access: yesIET Circuits, Devices & Systems, 2008
The possibility of using devices based on field-effect principles for detecting DNA hybridisation events is an attractive and low-cost alternative to optical reading techniques. Experiments have shown that a change in the threshold voltage of a few millivolts can be attributed to successful hybridisation of targets to probe oligonucleotides tethered on

Analytical model for electrohydrodynamic thrust [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020
Electrohydrodynamic (EHD) thrust is produced when ionized fluid is accelerated in an electric field due to the momentum transfer between the charged species and neutral molecules. We extend the previously reported analytical model that couples space charge, electric field and momentum transfer to derive thrust force in one-dimensional planar ...

Recruitment of Brd3 and Brd4 to acetylated chromatin is essential for proinflammatory cytokine-induced matrix-degrading enzyme expression

open access: yesJournal of Orthopaedic Surgery and Research, 2019
Background Proinflammatory cytokines, which can upregulate the expression of matrix-degrading enzymes in chondrocytes, play important roles in the development of osteoarthritis.

Temperature Dependency Model in Pressure Measurement for the Motion-Capturing Pressure-Sensitive Paint Method

open access: yesSensors, 2023
Pressure-sensitive paint (PSP) has received significant attention for capturing surface pressure in recent years. One major source of uncertainty in PSP measurements, temperature dependency, stems from the fundamental photophysical process that allows ...

Analytical approximation for single-impurity Anderson model [PDF]

open access: yes, 2009
We have applied the recently developed dual fermion technique to the spectral properties of single-band Anderson impurity problem (SIAM). In our approach a series expansion is constructed in vertices of the corresponding atomic Hamiltonian problem.

Analyticity in Hubbard Models [PDF]

open access: yesJournal of Statistical Physics, 1999
The Hubbard model describes a lattice system of quantum particles with local (on-site) interactions. Its free energy is analytic when βt is small, or βt^2/U is small; here, βis the inverse temperature, U the on-site repulsion and t the hopping coefficient.

Modeling and Simulation of a Novel Low-Speed High-Torque Permanent Magnet Synchronous Motor with Asymmetric Stator Slots

open access: yesMachines, 2022
Focusing on the unstable electromagnetic performance of an air gap magnetic field caused by torque ripple and harmonic interference of a multi-slot and multi-pole low-speed high-torque permanent magnet synchronous motor (LHPMSM), an asymmetric stator ...
