Measuring cellular traction forces on non-planar substrates

, 2016
Animal cells use traction forces to sense the mechanics and geometry of their environment. Measuring these traction forces requires a workflow combining cell experiments, image processing and force reconstruction based on elasticity theory.

Effective three-band model for double perovskites [PDF]

, 2002
We start from a six-band model describing the transition-metal t2g orbitals of half-metallic double perovskite systems, such as Sr2FeMoO6, in which only one of the transition metal ions (Fe) contains important intratomic repulsion Ufe. By eliminating the

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Research of total-focusing-imaging based on phase coherence and dB amplitude enhancement

AIP Advances
To address the issue of weak defect visualization in the ultrasonic total-focusing method (TFM) after denoising, this paper integrates Phase Coherence Imaging (PCI) and dB amplitude enhancement (dB) with the TFM.

Apports de la TFMi par rapport à la TFM

e-Journal of Nondestructive Testing, 2023
L’un des paramètres importants quand on utilise le TFM pour reconstruire une image est le choix du, ou des, modes de reconstruction. Le choix est intuitif pour une inspection en ondes Longitudinales à 0°, type recherche de corrosion : pas de conversion ...

Evaluation of tissue response of experimental calcium silicate‐based endodontic sealers: An in vivo study

European Journal of Oral Sciences, EarlyView.
Abstract The aim of this study was to evaluate whether the experimental sealers, composed of tricalcium silicate (CaSi) and CaSi supplemented with calcium hypochlorite (CaSi‐H), stimulate tissue repair. The tissue response of experimental materials was compared with commercially available materials Bio‐C sealer (BC sealer) and BioRoot (BROOT ...

The effect of ultrasound wave path estimation to defect characterization capability in half-skip total focusing method

Research and Review Journal of Nondestructive Testing, 2023
The total focusing method (TFM) is a post-processing imaging technique applied on full matrix capture (FMC) ultrasonic inspection (UT) dataset. In TFM the ultrasonic wave energy is synthetically focused on every pixel in the image region of interest ...

Microwave conductivity in the ferropnictides with specific application to Ba$_{1-x}$K$_x$Fe$_2$As$_2$

, 2009
We calculate the microwave conductivity of a two band superconductor with $s^\pm$ gap symmetry. Inelastic scattering is included approximately in a BCS model augmented by a temperature dependent quasiparticle scattering rate assumed, however, to be ...

Exploring the impact of Cabotegravir‐Rilpivirine long‐acting on weight gain, body composition and quality of life in adults living with HIV

HIV Medicine, EarlyView.
Abstract Introduction Long‐acting injectable antiretroviral therapy (ART) with Cabotegravir (CAB) and Rilpivirine (RPV) offers an alternative to daily oral regimens, improving adherence and patient satisfaction. However, its impact on body composition and metabolism remains underexplored.
