Measurement Science and Technology, 2016 This paper discusses the propagation of the instantaneous uncertainty of PIV measurements to statistical and instantaneous quantities of interest derived from the velocity field. The expression of the uncertainty of vorticity, velocity divergence, mean value and Reynolds stresses is derived.

Ultrasound PIV Uncertainty Quantification
14th International Symposium on Particle Image Velocimetry, 2021 Ultrasound Particle image velocimetry (UPIV) is a non-invasive flow measurement technique where acousticopaque flow tracers are injected into a working fluid and ensonified to create ultrasound images. These images are processed using PIV cross-correlation based algorithms to measure the velocity field (Kim et al., 2004).

Chemistry – A European Journal, EarlyView.ABSTRACT Hexanuclear cyclic Gd(III) coordination compounds are promising candidates for magnetic and magnetocaloric applications, yet systematic series remain rare due to synthetic challenges. We report the synthesis and characterization of five new complexes with the general formula [Gd(H3bt)(carboxylate)]6, employing four different carboxylate ...

New exact solutions for the discrete fourth Painlev\'e equation
, 1994 In this paper we derive a number of exact solutions of the discrete equation $$x_{n+1}x_{n-1}+x_n(x_{n+1}+x_{n-1})= {-2z_nx_n^3+(\eta-3\delta^{-2}-z_n^2)x_n^2+\mu^2\over (x_n+z_n+\gamma)(x_n+z_n-\gamma)},\eqno(1)$$ where $z_n=n\delta$ and $\eta$, $\delta$

Particle image velocimetry studies of bubble growth and detachment by high speed photography [PDF]
, 1997 An understanding of bubble flows is important in the design of process equipment, particularly in the chemical and power industries. In vapour-liquid processes the mass and heat transfer between the phases is dominated by the liquid-vapour interface and ...

Cytoskeleton, EarlyView.ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

From Vascular Smooth Muscle Cells to Folliculogenesis: What About Vasorin?
Frontiers in Medicine, 2018 First described in 1988, vasorin (VASN) is a transmembrane glycoprotein expressed during early mouse development, and with a less extent, in various organs and tissues (e.g., kidney, aorta, and brain) postnatally.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance
Droplet, EarlyView.Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

European Journal of Organic Chemistry, EarlyView.This work describes the synthesis of lactose‐ and glucose‐derived chiral ligands and their application in the catalytic enantioselective Friedel–Crafts alkylation of indole with a series of trans‐β‐nitrostyrenes. The optimal ligand was an acetate protected, lactose‐derived pyridyl imine and its zinc complex afforded ees up to 93% and yields up to 93 ...
