Telocentrosomes organize telomere gathering Y oshida et al. identify a new job for microtubule-organizing centers (MTOCs)—helping telomeres huddle during meiosis. The most famous MTOC is the centrosome, a permanent structure that serves as a hub for the cell’s microtubules and anchors the spindle during mitosis. But cells also deploy ephemeral MTOCs to perform other tasks. In fi ssion yeast, fo...

Individual animats trading independently can lead to a collective market behavior. Also, animats can be imbued with gathering capabilities, enabling it to survive in a resourcelled environment. We separately develop animats that are capable of trading and resource-gathering, and run experiments to determine the conditions for survivability of the animats. We then imbue all animats with trading ...

In this paper, we investigate the possibility to deterministically solve the gathering problem (GP) with weak robots (anonymous, autonomous, disoriented, deaf and dumb, and oblivious). We introduce strong multiplicity detection as the ability for the robots to detect the exact number of robots located at a given position. We show that with strong multiplicity detection, there exists a determini...

A " requirement " is a necessary attribute in a system, a statement that identifies a capability, characteristic, or quality factor of a system in order for it to have value and utility to a user [1]. According to Steve McConnell in Software Project Survival Guide, " The most difficult part of requirements gathering is not documenting what the users 'want'; it is the effort of helping users fig...

Designing autonomous systems to perform reconnaissance and surveillance missions is especially challenging. Platforms must coordinate, to make on-line decisions about what to sense, what to communicate and how to manoeuvre to achieve their mission goals. A first step in achieving consistent, coordinated decision making is to provide a means for rapid and efficient distribution of information be...

We describe Razor, a planning-based information-gathering agent that assists users by automatically determining which Internet information sites are relevant to their query, accessing those sites in parallel, and integrating the results. Razor uses a disjunctive graphbased plan representation. It then uses a novel and powerful form of local completeness reasoning in order to transform those pla...

The detection of biomolecules on Solar System bodies can help us to understand how life emerged Earth and may be distributed in our System. However, the chemical signatures planets or their moons is challenging. A variety parameters must considered, such as a suited landing site location, geological environmental processes favourable life, strategies, application appropriate sensitive instrumen...

Flood risk is increasing due to climate change and the growth of the potential consequences of flooding. Analysing how flood-proof the spatial plan is, therefore becomes more important. Since most spatial planners have limited knowledge concerning flood risk, the Netherlands’ Directorate-General for Public Works and Water Management commissioned the creation of an instrument that can be used by...

OBJECTIVES To compare student and faculty perceptions of the delivery and achievement of professional competencies in a doctor of pharmacy program in order to provide data for both accountability and curricular improvement purposes. DESIGN A survey instrument was designed based on current learning theory, and 76 specific competency statements generated from mission and goal statements of The ...
