Analytical Model for the Depth Progress during Laser Micromachining of V-Shaped Grooves

Micromachines, 2022
An analytical model is presented that allows predicting the progress and the final depth obtained by laser micromachining of grooves in metals with ultrashort laser pulses. The model assumes that micromachined grooves feature a V-shaped geometry and that

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

Biology 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]

Journal 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 ...

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

Journal 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

Sensors, 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 ...

Analytic modelling of biotransistors

IET 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

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

Machines, 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 ...

Analyticity in Hubbard Models [PDF]

Journal 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.

Analytical modelling of hot-spot traffic in deterministically-routed k-ary n-cubes [PDF]

, 2005
Many research studies have proposed analytical models to evaluate the performance of k-ary n-cubes with deterministic wormhole routing. Such models however have so far been confined to uniform traffic distributions.
