Light scattered from spherical bubbles in water manifests an enhancement in the backward direction analogous to the well-known optical glory of a drop. Unlike the glory for water drops, in which the rays travel partially on the drop's surface, the glory for bubbles is due to rays that are refracted and multiply reflected within the scatterer and is an example of a transmitted wave glory. Photog...

Glutamate released at synapses in the CA1 region of the hippocampus escapes the synaptic cleft and activates extrasynaptic targets; it also may "spill over" into neighboring synapses and activate receptors there. Glutamate transporters in glial membranes restrict extrasynaptic diffusion, but it is unclear whether neuronal glutamate transporters also limit transmitter diffusion and receptor acti...

One common approach to generate lightweight materials with high specific strength and stiffness is the incorporation of stiff hollow microparticles (also known as bubbles or microballoons) into a polymeric matrix. The mechanical properties of these composites, also known as syntactic foams, greatly depend on those of the hollow microparticles. It is critical to precisely control the properties ...

In this paper, we propose a simple method for simulating the generation, growth and motion of bubbles in carbonated water. Bubbles are known to be generated at small air pockets on the surfaces of objects, such as a glass or a stirrer, and on the microscopic dusts in carbonated water. The number of bubbles and their growth rates differ according to the materials of the objects. In addition, the...

Variation in intensity of scattered light from cavitation bubbles in an ultrasonic standing wave field at different contents of dissolved air is studied experimentally. The number of cavitation bubbles that repeat expansion and contraction correlates with the sonochemical reaction yield and the evaluation of the number of bubbles is important for perspective on the yield. Peak-to-peak of intens...

Keyword-based linked data information retrieval is an easy choice for general-purpose users, but the implementation of such an approach is a challenge because mere keywords do not hold semantic information. Some studies have incorporated templates in an effort to bridge this gap, but most such approaches have proven ineffective because of inefficient template management. Because linked data can...

Model updating concerns the modification of an existing but inaccurate model with measured data. For models characterized by quadratic pencils, the measured data usually involve incomplete knowledge of natural frequencies, mode shapes, or other spectral information. In conducting the updating, it is often desirable to match only the part of observed data without tampering with the other part of...

This article investigates the impact of terrorist attacks on global capital markets. We find economic consequences of terrorist attacks spillover through trading partners. When a bigger economy (measured by GDP) is targeted, the spillover is specifically prominent for economically smaller trading partners. Such partners see a -2.5% reduction in national stock indices. Odds for smaller trading p...

According to the knowledge spillover theory of entrepreneurship, people start a new firm because they are not able to commercialize their ideas and knowledge within the context of an incumbent firm or organization. Entrepreneurship therefore serves as a conduit for the spillover of knowledge from the firm or organization where that knowledge was created to its commercialization in the organizat...
