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

open access: yessteel 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 ...

Evidence for Substructure on the Inner Broad Line Region of the Lensed Quasar SDSS J1004+4112 from the Recurrence of Microlensing in the C IV Emission Line

open access: yesThe Astrophysical Journal
We use microlensing to probe the inner broad line region (BLR) of the lensed quasar SDSS J1004+4112, finding evidence of substructure. We study the recurrent microlensing events observed in the blue wing of the C IV emission line in image A of this ...

A novel gravitational lensing feature by wormholes

open access: yesPhysics Letters B, 2019
Horizonless compact objects with light rings (or photon spheres) are becoming increasingly popular in recent years for several reasons. In this paper, we show that a horizonless object such as a wormhole of Morris–Thorne type can have two photon spheres.

Finding diamonds in the rough: Targeted Sub-threshold Search for Strongly-lensed Gravitational-wave Events

open access: yes, 2021
Strong gravitational lensing of gravitational waves can produce duplicate signals separated in time with different amplitudes. We consider the case in which strong lensing produces identifiable gravitational-wave events and weaker sub-threshold signals ...

The Export and Financial Effects of Immigrant Team Composition in International New Ventures

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT Immigrant‐owned international new ventures (INVs) often partner with non‐immigrant entrepreneurs as co‐owners. Their mixed immigrant‐nonimmigrant teams could engender varied perspectives. But it is unclear whether such cognitive diversity improves their international strategy and performance.

Sociology and The Complexity of What Is Missing

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT What is ‘missed’ by sociological literature underpinned by assumptions of presence that a missing approach can rectify? I appropriate a metaphysics of presence and an alternative focus on what is missing as ontological foci to revisit complexity studies in sociology.

The necessity of dark matter in MOND within galactic scales [PDF]

open access: yes, 2008
To further test MOdified Newtonian Dynamics (MOND) on galactic scales -- originally proposed to explain the rotation curves of disk galaxies without dark matter -- we study a sample of six strong gravitational lensing early-type galaxies from the CASTLES
