Provable Algorithms for Learning and Variational Inference in Undirected Graphical Models
… variational inference on an Ising model in the optimal density regime. These different problems illustrate a set of key principles, such as the diverse algorithmic applications of “pinning” variables in graphical models. We also show in some cases that these results are nearly optimal due to …

Radiative transfer and thermal performance levels in foam insulation boardstocks
… time-averaged performance as a function of foam density, mean cell diameter, and fractional distribution of solid polymer. The results of the simulation indicate that for a 15 year service life, the optimal density is approximately 3 lb / ft3.

Value of soil sampling and optimal sampling density for a variable rate seed application
… believe that a single sample per hectare is the optimal sampling density to generate the most statistically significant information on soil nutrients and physical conditions. The literature, however, does not describe whether the recommended sampling density is the optimal density in terms of …

Topology Optimization Using Load Path and Homogenization
… which is found by solving the Euler-Lagrange optimality criteria. The optimal density of a structure is derived using optimality criteria and optimized load paths. To attain the topology of the microstructure, the principal load paths that follow the optimal principal stress directions are …

Cell-cell and cell-medium interactions in the growth of mouse embryonic stem cells
… mouse ESCs. We demonstrate the existence of an optimal density for 2-day culture of mouse ESCs. Further, we demonstrate that the increase in growth with plating density (103-104 cells/cm2) is at least partly due to the existence of one or more survival-enhancing autocrine factor(s) in mouse ESC …

Properties of p-modulus on radially symmetric infinite trees
… of a standard convex optimization problem. The optimal value of this problem provides information about the underlying graph, and has been shown to be closely related to several important graph theoretic quantities including shortest path, effective resistance, and minimum cut. Some of these …

Development of microelectrode arrays for real-time monitoring of alkaline phosphatase release from cells in clinical analysis
… Balb/c 3T3, A549 and MCF-7 cells displayed an optimal initial density of 40×103 cell/mL, whereas the Ht20 cells displayed an optimal density of 80×103 cell/mL. This was compatible with the hemocytometer and microscope images. The kinetic enzyme assay of ALP release based on the absorbance …

Studies on the Complement Receptor of a Human Lymphoblastoid Cell Line
… method (in which cells grow for some time at suboptimal cell densities), and CR+ cells always appeared in cultures of cells kept at optimal density in the logarithmic phase of growth. These were the only conditions found to modify the expression of the receptor. Since 1) the growth rates of CR+ …

Extremal Problems for Cycles, Paths and Set-Systems
… in a random subgraph of a graph with a nearly optimal density. Finally, we also present further applications of our main tool (the Key Lemma) for proving results on Ramsey-type problems about cycles in sparse random graphs. In Chapter 3 we count at least how many Hamilton cycles one can find in …
