ECHO CHAMBERS AND EPISTEMIC BUBBLES
Episteme, 2018 Discussion of the phenomena of post-truth and fake news often implicates the closed epistemic networks of social media. The recent conversation has, however, blurred two distinct social epistemic phenomena.

BUBBLES HERE, BUBBLES THERE, BUBBLES EVERYWHERE
Journal of the American College of Cardiology, 2015 A 68-year-old male with a history of diabetes mellitus, hypertension and end stage renal disease, presented with sudden onset left sided weakness during dialysis. The patient was comfortable with normal vital signs and had an isolated left sided hemiparesis.

Graphical Models, 2009 We present a novel framework based on a continuous fluid simulator for general simulation of realistic bubbles, with which we can handle as many significant dynamic bubble effects as possible. To capture nature of the very thin liquid film of bubbles, we have developed a regional level set method allowing multi-manifold interface tracking. The regional

Interactions between a central bubble and a surrounding bubble cluster [PDF]
, 2023 The interaction of multiple bubbles is a complex physical problem. A simplified case of multiple bubbles is studied theoretically with a bubble located at the center of a circular bubble cluster. All bubbles in the cluster are equally spaced and own the same initial conditions as the central bubble.

Detecting West Texas Intermediate (WTI) Prices’ Bubble Periods
Energies, 2019 Oil prices have had considerable surges and bursts since the first oil crisis of 1973. Until then its price was stable, with almost zero volatility. Since then, apart from the two oil crises of 1973 and 1978/9, oil prices had consecutive bubble episodes ...

Velocity distribution in the boundary layer of a bubble rising with a rectilinear motion
Nihon Kikai Gakkai ronbunshu, 2020 The boundary layer of a bubble is an important factor that determines its rising velocity. But it is generally very thin to simulate using typical interface capturing method, such as volume of fluid method.

Tribonucleation of bubbles [PDF]
Proceedings of the National Academy of Sciences, 2014 SignificanceMicroscopic gas–vapor bubbles play an important role in various processes in nature, industry, and medicine. Sometimes they are desired: to lower the temperature at which a liquid starts to boil or to enhance the contrast in medical ultrasound applications. In other cases, bubbles are harmful: they cause damage when expanding and collapsing

Bubbles, Blind-Spots and Brexit
Risks, 2017 In this paper we develop a well-established financial model to investigate whether bubbles were present in opinion polls and betting markets prior to the UK’s vote on EU membership on 23 June 2016. The importance of our contribution is threefold. Firstly,

Review on Efficiency and Anomalies in Stock Markets
Economies, 2020 The efficient-market hypothesis (EMH) is one of the most important economic and financial hypotheses that have been tested over the past century. Due to many abnormal phenomena and conflicting evidence, otherwise known as anomalies against EMH, some ...

Scaling laws for jets of single cavitation bubbles [PDF]
Journal of Fluid Mechanics, 2016 Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearances, and propose a unified framework to describe their dynamics by using ...
