Modeling the separation of water‐in‐oil emulsions in continuously fed gravity settlers using millifluidic experiments

AIChE Journal, EarlyView.
Abstract Emulsion separation remains a persistent challenge in chemical and process industries due to the metastable nature of dispersed droplets. In gravity separators, the overall separation rate is governed by the formation of a densely packed zone (DPZ) of deforming and coalescing droplets that mediates between the dispersed and continuous phases ...

Pixelated Reconstruction of Foreground Density and Background Surface Brightness in Gravitational Lensing Systems Using Recurrent Inference Machines

The Astrophysical Journal, 2023
Modeling strong gravitational lenses in order to quantify distortions in the images of background sources and to reconstruct the mass density in foreground lenses has been a difficult computational challenge.

Gravitomagnetic Effects in the Propagation of Electromagnetic Waves in Variable Gravitational Fields of Arbitrary-Moving and Spinning Bodies [PDF]

, 2001
Propagation of light in the gravitational field of self-gravitating spinning bodies moving with arbitrary velocities is discussed. The gravitational field is assumed to be "weak" everywhere. Equations of motion of a light ray are solved in the first post-

ParamNet: A Physics‐Guided Deep Learning Framework for Intelligent Self‐Inversion of Vacuum Optical Levitation Systems

Advanced Intelligent Systems, EarlyView.
A physics‐guided deep learning framework, ParamNet, is introduced for the intelligent self‐inversion of vacuum optical tweezers. By fuzing dual‐branch time–frequency features with physical dynamical constraints, it achieves high‐accuracy calibration of trap parameters from short‐window, low‐frequency trajectories, outperforming traditional methods ...

QUASI-ANALYTICAL METHOD FOR IMAGES CONSTRUCTION FROM GRAVITATIONAL LENSES

Odessa Astronomical Publications, 2016
One of the main problems in the study of system of equations of the gravitational lens, is the computation of coordinates from the known position of the source. In the process of computing finds the solution of equations with two unknowns. The problem is

Galaxy mergers and gravitational lens statistics [PDF]

The Astrophysical Journal, 1994
We investigate the impact of hierarchical galaxy merging on the statistics of gravitational lensing of distant sources. Since no definite theoretical predictions for the merging history of luminous galaxies exist, we adopt a parametrized prescription, which allows us to adjust the expected number of pieces comprising a typical present galaxy at z=0.65.

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

An Additional Application of the Space Interferometry Mission to Gravitational Microlensing Experiments

, 1999
Despite the detection of a large number of gravitational microlensing events, the nature of Galactic dark matter remains very uncertain. This uncertainty is due to two major reasons: the lens parameter degeneracy in the measured Einstein timescale and ...

Harnessing the Interfacial Activity of Soluble Faba Protein‐Tannic Acid Conjugates for Enhanced Lipid Oxidative Stability of Oil‐in‐Water Emulsions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In oil‐in‐water emulsions, lipid oxidation begins at the interface between the two phases. One strategy to slow down this process is to place antioxidants at the interface, where they can directly block oxidative reactions. This study explored that idea by conjugating soluble faba bean protein with tannic acid using the free‐radical grafting ...

Non-parametric inversion of gravitational lensing systems with few images using a multi-objective genetic algorithm [PDF]

, 2007
Galaxies acting as gravitational lenses are surrounded by, at most, a handful of images. This apparent paucity of information forces one to make the best possible use of what information is available to invert the lens system.
