ATF6 is an endoplasmic reticulum (ER) membrane-bound transcription factor that regulates various cellular functions. The purpose of this study was to investigate the role of ATF6 in odontoblast differentiation. Rat tooth germs were isolated, changes in gene expression were evaluated over time, and localization of ATF6 was determined by immunohistochemistry.(More)
The pervasiveness of computing has extended into domestic realms, including the dining room. Beyond simply a place to consume food, the dining room is a social hub where family members meet and share experiences. Yet busy lifestyles can make it difficult to spend social time with your family. To provide a new solution for family bonding, this paper presents(More)
We refer to human-robot relationships as Lovotics. In this paper a design process for Lovotics is presented. In order to invoke these relationships, technological solutions can only take us so far. Design played an important role in order to engage users to explore the possibilities of bi-directional, human-robot love. We conducted a user-centric study in(More)
Families have strong desires to have fun together, even at a distance. "Food Media" is an exploration of appropriating food and food activities as a medium for family communication and entertainment, across generations and over a distance. Traditionally, food has always been a social hub which brings people together for communication and entertainment. As(More)
We present a new methodology based on ferromagnetic fluids in which the user can have direct interaction (input/output) through a tangible and malleable interface. Liquid Interfaces uses the physical qualities of ferromagnetic fluids in combination with capacitive, multi-touch technology, to produce a 3D, multi-touch interface where actuation,(More)
Previously, PAHX-AP1 (PAHX-associated protein 1) was isolated as a novel protein to interact with Refsum disease gene product (phytanoyl-CoA alpha-hydroxylase, PAHX) and specifically expressed in mouse brain. PAHX-AP1 is also suggested to be involved in the development of the central neurologic deficits of Refsum disease. To clarify its function, we have(More)
In this paper we analyze the works of the Keio-NUS CUTE Center at the National University of Singapore in order to uncover the dispositions of "analogness" and "digitalness" in regards to the relationship between users and interfaces. By comparing concepts of embodiment from a philosophical perspective, paired with the computer science treatment of analog(More)
We present an OUI that combines Hall Effect sensing and actuation through electromagnetically-manipulated ferrofluid. The movement of magnets worn on the fingertips, over a surface embedded with a Hall Effect sensor array and electromagnets, gives the user the ability to interact with ferrofluid. This system provides a three-dimensional, physically animated(More)
In this paper we propose a cognitive model designed to identify the determinants of human willingness to collaborate with a robot counterpart. We specifically look towards factors that influence our assessment of our own capacity and that of a robot prior to and during collaboration. Through the employment of the proposed model, visual aesthetics can be(More)
