Strong Gravitational Lens Modelling [PDF]

, 2019
The objective of this project is to examine the extent to which strong gravitational lensing can constrain cosmological parameters. I present the results of applying a modified version of an existing model of strong gravitational lensing to forthcoming surveys by Euclid, currently scheduled to launch in 2021, and investigate also how the model may be ...

Step‐Ladder Bioprinting to Align Collagen Fibers for Anisotropic Tissue Fabrication

Small, EarlyView.
The step‐ladder printing platform includes successive segments of channels with varying widths in a custom barrel design. This design allows for improved anisotropy of collagen fibers during extrusion. To demonstrate its effectiveness, corneal constructs with high transparency and shape fidelity, as well as articular cartilage constructs, displaying ...

Weak-lensing Approximation of Wave-optics Effects from General Symmetric Lens Profiles

The Astrophysical Journal
Gravitational lensing of electromagnetic (EM) waves has yielded many profound discoveries across fundamental physics, astronomy, astrophysics, and cosmology. Similar to EM waves, gravitational waves (GWs) can also be lensed.

The Biased Interaction Game: A System Theoretic Approach to the Emergence of Inequality, Hierarchy, and the Implications for the Likelihood of Cooperation

Systems Research and Behavioral Science, EarlyView.
ABSTRACT The emergence of cooperation in natural selection has been successfully studied using game theory and, despite the underlying selfish nature of the evolutionary process, a spectrum of plausible mechanisms have been proposed to determine the conditions under which cooperative behaviour is likely to occur.

Exploring Weak Gravitational Lensing Effects by a Regular Black Hole

Spektra: Jurnal Fisika dan Aplikasinya
Gravitational lensing is one of the physical consequences of Einstein’s general theory of relativity, which has been observationally confirmed. This work aims to study the weak gravitational lensing scenario where the lens is a spherically symmetric ...

Experimental Investigations on the Impact of Operational Conditions on Bubble Dynamics and the Resulting Vibrations in Gas‐Stirred Ladles

steel research international, EarlyView.
This study applies sensitive vibration sensors to investigate gas bubble behavior in liquid metal during argon injection. Analysis of vibration signals provides insights into bubble evolution and the influence of gas flow and surface pressure. The results provide a basis for improved vibration‐based two‐phase flow models, enhancing accuracy in ...
