We have developed a highly scalable application, called Shoal, for tracking and utilizing a distributed set of HTTP web caches. Our application uses the Squid HTTP cache. Squid servers advertise their existence to the Shoal server via AMQP messaging by running Shoal Agent. The Shoal server provides a simple REST interface that allows clients to determine their closest Squid cache. Our goal is t...

Recent experiments on superconducting loops have demonstrated coherent superpositions between macroscopic quantum states. In the experiment of the superconducting persistent-current qubit, a dc SQUID measures the magnetic flux generated by the persistent currents of the macroscopic quantum states. Due to the inductive interaction between the qubit and the SQUID, the SQUID has various back effec...

We investigated the use of India ink as an indicator of root canal sealing ability. Sealing ability is one of the most important factors required of root canal cements. Various dyes have been used for this purpose. Methylene blue, radioisotopes and India ink have all been tried. However, there is no evidence that India ink is suitable as an indicator. We measured the particle size distribution ...

We developed a new softening technology applicable to the main body of the jumbo squid Dosidicus gigas; this will aid in squid consumption by elderly individuals and those who have masticatory and dysphagia problems. Protease solutions were injected into jumbo squid and hardness was measured using a texture analyzer. Seven enzymes were tested. Jumbo squid became progressively softer during brom...

We propose a new spectral prediction model as well as new approaches for modeling ink spreading which occurs when printing ink layer superpositions. The spectral prediction model enhances the classical ClapperYule model by taking into account the fact that proportionally more incident light through a given colorant surface is reflected back onto the same colorant surface than onto other coloran...

We study the metastable response of a highly hysteretic dc superconducting quantum interference device (SQUID) made of a niobium loop interrupted by two nanobridges. We excite the SQUID with an alternating current and with direct magnetic flux, and find different stability zones forming diamond-like structures in the measured voltage across the SQUID. When such a SQUID is embedded in a transmis...

This study aims at exploring ink spreading, which causes significant colour deviations in ink-jet printing. We present a method for investigating this phenomenon by considering only a limited number of cases. Using a combinatorial approach based on Pólya’s counting theory, we determine a small set of ink drop configurations which allows to deduce the ink spreading in all other cases. This impro...

The seahare Aplysia spp. extracts many of its defensive chemicals from its red seaweed diet, including its purple ink, which is an effective deterrent against predators such as anemones and crabs. It is believed that the inking behavior is a high-threshold, all-or-none fixed act that nearly completely depletes the seahare of its ink supply. If a seahare depletes its gland of ink, it must seek o...

Fractionation is important to understand someone’s health. How we can simulate blood fractionation through a simple, inexpensive ink spread experiment more about blood fractionation and liquid chromatography. Cotton will spread on ink the most because it has the most pores. Pilot ink spreads fast because it is water-based (low viscosity). Higher temperatures should result in more spread because...
