This paper analyzes the possibility and the consequences of rational bubbles in a dynamic economy where financially constrained firms demand and supply liquidity. Bubbles are more likely to emerge, the scarcer the supply of outside liquidity and the more limited the pledgeability of corporate income; they crowd investment in (out) when liquidity is ...

LIN28B Promotes Cancer Cell Dissemination and Angiogenesis
Children diagnosed with high‐risk neuroblastoma have a 5‐year event‐free survival rate of less than 50% and poor outcomes after recurrence. Deregulation of the LIN28B oncogene can be addressed in these patients. Upregulation of LIN28B is shown to support the metastatic cascade.

Evolution of an elliptical bubble in an accelerating extensional flow [PDF]
Mathematical models that describe the dynamical behavior of a thin gas bubble embedded in a glass fiber during a fiber drawing process have been discussed and analyzed.

Bubble wall perturbations coupled with gravitational waves [PDF]
We study a coupled system of gravitational waves and a domain wall which is the boundary of a vacuum bubble in de Sitter spacetime. To treat the system, we use the metric junction formalism of Israel.

We show that an increase in a stock’s breadth of institutional ownership or turnover is followed by a significant, but temporary, increase in its CAPM beta estimate and a decrease in its CAPM alpha. The increasing effect of breadth of ownership on beta estimates is mainly driven by short-term investors.

A laboratory‐scale procedure is developed to evaluate the efficiency of melt‐cleaning and drossing fluxes during aluminium alloy recycling, studying their effects on melt cleanliness and tensile properties of secondary foundry alloys. This work provides a practical tool for foundries and aluminium refiners to assess the efficiency of salt fluxes in ...

Gas–liquid flow in the dissolved air flotation (DAF) tank was studied through computational fluid dynamics through the realizable k-ε model and the population balance model (PBM) to predict the gas content of different flotation mediums (air, carbon ...

The extreme environment formed during bubble collapse can cause a series of chemical reactions inside the bubble, and multiple products (i.e., ˙OH, H˙, O, H2, and HO2˙, etc.) are produced, which is called sonochemistry. In this study, a new model is used

Bubble Lift-off Size in Forced Convective Subcooled Boiling Flow [PDF]
Forced convective subcooled boiling flow experiments were conducted in a BWR-scaled vertical upward annular channel. Water was used as the testing fluid, and the tests were performed at atmospheric pressure.

This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...
