Prey species possess numerous strategies to reduce predation. One tactic is to respond with antipredator behaviours when conspecific alarm cues are detected. The sea hare Aplysia californica defends itself from predators in many ways, one of which is releasing ink and opaline upon attack. Previous work showed that a mixture of ink and opaline from A. californica causes conspecifics to respond w...

BACKGROUND Dermoscopy is a helpful tool that can assist experienced users improve the diagnostic accuracy for pigmented lesions in acral sites. As a simplification, one can assume that if pigment is found predominantly in the furrows, the lesion can be considered benign, and if the pigmentation is present predominantly on the ridges, the lesion should be considered malignant. The differentiatio...

The MetallicArt technique is used as a visual security feature to hide patterns in CMY images using an additional silver ink. The patterns are hidden under nonspecular viewing conditions and visible under specular viewing conditions. By varying the amount of silver ink, the authors control the intensity of the specular reflection of the printed pattern. Using a spectral reflection prediction mo...

Extracting characters from digital ink text is an essential step which leads to more reliable recognition of text and also a prerequisite for structured editing. Casualness and diversity of handwriting input result in unsatisfied accuracy of extracted characters. Reprocessing the initial extracted characters based on context makes some considerable improvement. Therefore, this paper proposes an...

Major components of inks have molecules that are vibrationally active and thus give infrared spectra. These components are related to both the type of ink involved, and they are part of a total system, along with possible metal ion-based molecules, that make up the chemistry of inks. In this proposed study, modern synchrotron radiation-based---as well as conventional---infrared spectroscopy wil...

Drop-on-demand (DOD) bioprinting has attracted huge attention for numerous biological applications due to its precise control over material volume and deposition pattern in a contactless printing approach. 3D bioprinting is still an emerging field and more work is required to improve the viability and homogeneity of printed cells during the printing process. Here, a general purpose bio-ink was ...

We present an interaction technique for classroom teaching, through our software for electronic whiteboards, which allows the writing surfaces of the boards to be used as if they were ordinary whiteboards. Toolboxes that provide, among other things, options for changing ink properties, editing commands, and accessing files have been ubiquitously tucked away in the background. These tools appear...

Pen computing devices provide a natural interface for annotating documents with freeform digital ink. However, digital ink annotations are usually larger and sloppier than real ink annotations on paper. We present DIZI, a focus+context interface that zooms up a region of the underlying document for inking. Users write in the zoomed region at a comfortable size for the device. When the zoom regi...
