Eric Pearlman for discussions on intrastromal injections. Disclosures The authors have no financial conflicts of interest.  ...  However, in this model, live amoebae were not isolated from infected cornea, and the impact of infecting with dead amoebae was not assessed.  ...  Numerous parasites were seen in the cornea on day 3 followed by clearance with a decreased parasite load seen on day 6 p.i. (Fig. 1C) .  ...

Exploiting process lifetime distributions for dynamic load balancing

Mor Harchol-Balter, Allen B. Downey
1995 ACM SIGOPS Operating Systems Review  
We consider policies for CPU load balancing in networks of workstations.  ...  We address the question of whether preemptive migration (migrating active processes) is necessary, or whether remote execution (migrating processes only at the time of birth) is sufficient for load balancing  ...  ACKNOWLEDGMENTS We would like to thank Tom Anderson and the members of the NOW group for comments and suggestions on our experimental setup.  ...

Paraburkholderia Symbionts Display Variable Infection Patterns That Are Not Predictive of Amoeba Host Outcomes

Jacob W. Miller, Colleen R. Bocke, Andrew R. Tresslar, Emily M. Schniepp, Susanne DiSalvo
2020 Genes  
This results in final infection loads that do not strongly correlate to final host outcomes, suggesting other genetic factors that are not a direct cause or consequence of symbiont abundance impact host  ...  Here, we quantify infection patterns of diverse Paraburkholderia symbiont genotypes in their amoeba host Dictyostelium discoideum and probe the relationship between these patterns and host outcomes.  ...  We also thank Joan Strassmann and David Queller for amoeba and symbiont isolates.

Cluster Computing [chapter]

Mark Baker, John Brooke, Ken Hawick, Rajkumar Buyya
2001 Lecture Notes in Computer Science  
Generally a workstation will be "owned" by, for example, an individual, a groups, a department, or an organisation. They are dedicated to the exclusive use by the "owners".  ...  Typically, there are three types of "owner": • Ones who use their workstations for sending and receiving mail or preparing papers, such as administrative staff, librarian, theoreticians, etc. • Ones involved  ...  of load balancing a cluster (migrating processes of heavily load workstation and running them on lightly loaded ones).  ...

Process migration

Dejan S. Milojičić, Fred Douglis, Yves Paindaveine, Richard Wheeler, Songnian Zhou
2000 ACM Computing Surveys  
The benefits and drawbacks of process migration depend on the details of implementation and, therefore, this paper focuses on practical matters.  ...  This survey reviews the field of process migration by summarizing the key concepts and giving an overview of the most important implementations.  ...  The anonymous reviewers provided an extensive list of general, as well as very detailed, suggestions that have strengthened our focus, presentation and correctness of the paper.  ...

Mechanosensitive Adhesion Explains Stepping Motility in Amoeboid Cells

Calina A. Copos, Robert D. Guy, Sam Walcott, Juan Carlos del Alamo, Alex Mogilner
2017 Biophysical Journal  
Here, we develop a simple model to mechanistically explain the emergence of periodic changes in length and spatiotemporal dynamics of traction forces measured in chemotaxing uni-cellular amoeba, Dictyostelium  ...  Forward Euler method is used to evolve the force balance equation at each point on the structure. The cell achieves an equilibrated shape before migration is initiated.  ...  Despite the coarseness of our simple model, perturbations to the mechanical model parameters impact the frequency of the motility cycle and the migration speed consistent with experiments.  ...

Malthe Hvas, Egil Karlsbakk, Stig Mæhle, Daniel William Wright, Frode Oppedal
2017 Conservation Physiology  
The parasitic amoeba Paramoeba perurans is an aetiological agent of amoebic gill disease (AGD), a serious problem in seawater salmonid aquaculture globally.  ...  Currently little is known about the impact of AGD on wild fish, but in a time with global warming and increasing aquaculture production this potential threat could be on the rise.  ...  M.H. conducted swim tunnel experiments and sampling, while E.K. and S.M. did the histological examinations and PCR analyses.  ...
