The Astrophysical Journal, 2022 We present new light curves for the four bright images of the five image cluster-lensed quasar gravitational lens system SDSS J1004+4112. The light curves span 14.5 yr and allow the measurement of the time delay between the trailing bright quasar image D

Particle saltation trajectories in supercritical open channel flows: Roughness effect
Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3588-3610, December 2022., 2022 This study investigates single particle trajectories in supercritical open channel flows under different hydraulic and roughness conditions. Therefore, it helps to get a better understanding on the mechanics and prediction of bedrock incision and hydro‐abrasion occurring in steep bedrock rivers and hydraulic structures.

Strong Gravitational Lensing in the Einstein-Proca Theory [PDF]
Int J Theor Phys (2015) 54:1245-1252, 2015 Adopting the strong field limit approach, we investigate the strong gravitational lensing of a spherically symmetric spacetime in the Einstein-Proca theory. With the strong field limit coefficient, three observable quantities are obtained, which are the innermost relativistic image, the deflection angle and the ratio of the flux.

Strong gravitational lensing by DHOST black holes [PDF]
, 2020 The gravitational deflection of light in the strong field limit is an important test for alternative theories of gravity. However, solutions for the metric that allow for analytic computations are not always available.

Polyacrylic Acid Copolymers as Adhesion‐Adapted Model Materials for Cleaning Tests
Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023 Acrylic acid (AA) copolymers adhere physically to metallic surfaces and are used for production of layers which shall mimic real filmic contamination layers for cleaning tests. To further adjust the polymers to the reference contaminations the polarity of the copolymers is varied not only by the percentage of carboxy groups but also by additional ...

Formation and growth of multiple, distinct ice lenses in frost heave
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 1, Page 82-105, January 2023., 2023 Abstract This paper presents a fully coupled thermo‐hydro‐mechanical (THM) model which simulates frost heave in fully saturated soils. The model is able to simulate the formation and growth of multiple distinct ice lenses. The basic equations of the system were derived using the continuum theory of mixtures, nonequilibrium thermodynamics, and fracture ...

Stellar prospects for FRB gravitational lensing [PDF]
, 2022 Gravitational lensing of fast radio bursts (FRBs) offers an exciting avenue for several cosmological applications. However, it is not yet clear how many such events future surveys will detect nor how to optimally find them. We use the known properties of FRBs to forecast detection rates of gravitational lensing on delay timescales from microseconds to ...
