The whole-part organizational method is one which pervades human thinking, and as such plays an important role in data modeling. This is especially true in manufacturing, design, graphics, multi-media, and document processing|areas targeted by object-oriented databases (OODBs). In this paper, we formally deene OODB relationships which provide constraints and functionalities that enforce real-wo...
We propose a 2D display and camera arrangement for video communication systems that supports both spatial information between distant sites and user mobility. The implementation of this arrangement is called the “surrounding back screen method.” The method enables users to freely come from and go into other users’ spaces and provides every user with the direct pointing capability, since there i...
The cell cycle and the circadian clock communicate with each other, resulting in circadian-gated cell division cycles. Alterations in this network may lead to diseases such as cancer. Therefore, it is critical to identify molecular components that connect these two oscillators. However, molecular mechanisms between the clock and the cell cycle remain largely unknown. A model filamentous fungus,...
In leaves of the maize tangled1 (tan1) mutant, clusters of bundle sheath (BS)-like cells extend several cells distant from the veins, in association with the single layer of BS cells around the vein. We show that the BS-like cell clusters in tan1 leaves result from the continued division of cells in the procambial/BS cell lineage that do not divide further in wild-type leaves. The ectopic BS-li...
Despite their pivotal role in plant development, control mechanisms for oriented cell divisions have remained elusive. Here, we describe how a precisely regulated cell division orientation switch in an Arabidopsis stem cell is controlled by upstream patterning factors. We show that the stem cell regulatory PLETHORA transcription factors induce division plane reorientation by local activation of...
