In this paper we demonstrate the application of time-varying graphs (TVGs) for modeling and analyzing multi-robot foremost coverage in dynamic environments. In particular, we consider the multi-robot, multi-depot Dynamic Map Visitation Problem (DMVP), in which a team of robots must visit a collection of critical locations as quickly as possible, in an environment that may change rapidly and unp...

There is an ever-increasing interest in investigating dynamics in timevarying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metrics that assess the relative importance of nodes along the temporal evolution of the dynamic complex network. For some TVG scenarios, however, more important than identifying the central nodes under a given node centra...

Photosystem II reaction centers comprised of the Dl, D2 and cytochrome b-559 polypeptides were isolated from welldefined oxygen-evolving reaction center preparations using either a combination of LiClO, and dodecyhnaltoside, or Triton X-100 alone. Yields of chlorophyll and cytochrome b-559 for both preparative methods were compared, and pigment contents were compared based on 2.0 b-559 per reac...

Recent issues of ARE Update featured articles evaluating the failures of two California marketing cooperatives, Tri Valley Growers (TVG) and Rice Growers Association (RGA). Along with Blue Anchor’s dissolution and Calavo’s conversion, these combined events have created doubts about the future of cooperatives in California agriculture. Restructured forms of cooperatives are emerging. For example...

We consider the Dynamic Map Visitation Problem (DMVP), in which a team of agents must visit a collection of critical locations as quickly as possible, in an environment that may change rapidly and unpredictably during the agents’ navigation. We apply recent formulations of time-varying graphs (TVGs) to DMVP, shedding new light on the computational hierarchy R ⊃ B ⊃ P of TVG classes by analyzing...

Background: Activation loop Y807F or juxtamembrane domain Y559F mutations compromise CSF-1 receptor-mediated macrophage proliferation. Results: Tyr-559 suppresses constitutive proliferative activity of Tyr-807; ligand-induced Tyr559 phosphorylation relieves this inhibition and activates pathways. Conclusion: Tyr-807 drives proliferation. Tyr-559 confers ligand dependence. Significance: How indi...

The development of photochemical activities in isolated barley plastids during illumination of dark-grown plants has been studied and compared with the behaviour of plastocyanin, cytochromes f, b-559(LP), b-563 and b-559(HP) and pigments P546 (C550) and P700. Electron-transport activity dependent on Photosystem 1 and cyclic photophosphorylation dependent on N-methylphenazonium methosulphate (ph...
