We present techniques that allow sharing of standardized digital ink in a heterogeneous collaborative environment. We explore the use of W3C InkML (Digital Ink Markup Language) and show how it is more flexible and suitable than other digital ink formats for this purpose. We discuss different possible digital ink sharing schemes using InkML and describe pros and disadvantages of each. We present...

We review the phenomena having an impact on the interaction between light, paper and color halftones. They comprise surface reflections and refractions at the air-paper interface, propagation of light within the paper, internal reflections at the paper-air interface, as well as ink spreading and trapping. We introduce basic notions from radiometry and optics, such as the definitions of radiant ...

Sublethal injury triggers long-lasting sensitization of defensive responses in most species examined, suggesting the involvement of powerful evolutionary selection pressures [1]. In humans, this persistent nociceptive sensitization is often accompanied by heightened sensations of pain and anxiety [2]. While experimental [3] and clinical [4] evidence support the adaptive value of immediate nocic...

This study presents the first target strength measurements of Dosidicus gigas, a large squid that is a key predator, a significant prey, and the target of an important fishery. Target strength of live, tethered squid was related to mantle length with values standardized to the length squared of -62.0, -67.4, -67.9, and -67.6 dB at 38, 70, 120, and 200 kHz, respectively. There were relatively sm...

Using jet propulsion, squid can swim at high speed or at low speed with good maneuverability, which makes them quiet valuable to be studied for biomimetic purposes. Vortex rings usually occur in the highly-unsteady jet flow in squid, and they play quite important roles in the jet propulsion of squid. This paper tries to investigate the squid jet structure by computational fluid dynamics (CFD) a...

The amino acid sequence was determined for squid calcium-binding protein (CaBP), a low molecular weight, high affinity calcium-binding protein from squid optic lobe. The sequence shows this protein to consist of 149 amino acids with an N-acetylated N terminus. The protein has a molecular weight of 16,894 and is homologous to calmodulin, which is also present in squid optic lobe (Head, J. F., Sp...

BACKGROUND India ink microscopy on cerebrospinal fluid is still utilized in resource limited settings for the diagnosis of cryptococcal meningitis despite its poor sensitivity. We hypothesized that staining fungal nucleic acids with fluorescent dyes instead of the capsule with India ink might improve sensitivity for the diagnosis of cryptococcal meningitis. METHODS We enrolled 96 HIV-infected...

One of the complex tasks in mass production of RF electronics is printing the communication antenna using electrically conductive ink. For example, this is very common for radiofrequency identification (RFID) tags. Electrical properties of the ink are mostly determined by conductive (e.g. silver) particles mixed into the ink solution and the way they ‘connect’ in the cured ink. It is also desir...

This paper is divided into two parts with the aim to compare visco-elastic structure relaxation of a presheared offset ink with observed ink tack development on a representative absorbent multi-coated paper. The methods used include oscillatory and shear rheometry in part I, and comparison with the SeGan Ink Surface Interaction Tester (ISIT) in part II. By diluting the ink with mineral oil, a p...
