The relationship between the secretion of interleukin 10 (IL-10) and nitric oxide (NO) by hamster peritoneal macrophages and their cytotoxic effects on the cells of those two melanoma lines was studied. The nonuniform reaction of macrophages from hamsters bearing two transplantable melanoma lines has been observed. An increase in the cytotoxicity of macrophages from hamsters bearing the amelano...

A prediction problem of the following variety is considered. A stationary random process w(.) of known spectrum is observed over 1 1 < a . Using these observed values, w(b) is to be predicted for some b with lbl>a. We present a physical interpretation of a solution to this problem due to Krein, which used the theory of inverse Sturm-Liouville problems. Our physical model involves a nonuniform l...

We present a computational method for quasi 3D unsteady flows of thin liquid films on a solid substrate. This method includes surface tension as well as gravity forces in order to model realistically the spreading on an arbitrarily inclined substrate. The method uses a positivity preserving scheme to avoid possible negative values of the fluid thickness near the fronts. The “contact line parado...

Nonuniform field runoff can reduce the effectiveness of filter strips that are a uniform size along a field margin. Effectiveness can be improved by placing more filter strip where the runoff load is greater and less where the load is smaller. A modeling analysis was conducted of the relationship between pollutant trapping efficiency and the ratio of filter strip area to upslope contributing ar...

We present a novel joint nonuniform illumination estimation and deblurring method for bar code signals based on a penalized nonlinear squares objective function. The objective function is based on the proper parameterization of a bar code signal and nonuniform illumination as well as a regularization on the illumination using a smoothness penalty. By the minimization of the objective function, ...

Ravikanth Pappu Massachusetts Institute of Technology Media Laboratory Spatial Imaging Group 20 Ames Street Cambridge, Massachusetts 02139 E-mail: [email protected] Abstract. An novel algorithm for computing holographic fringe patterns based on nonuniform sampling is described. We show both analytically and via simulation that nonuniform sampling reduces the number of samples required to repr...

In recent years, there has been considerable interest in the theory and design of filter bank transceivers due to their superior frequency response. In many applications, it is desired to have transceivers that can support multiple services with different incoming data rates and different quality-of-service requirements. Tomeet these requirements, we can either do resource allocation or design ...
