Using Content Provider Signals to Select Individual Content Items for a Content Item Campaign

This document describes a system and method in which signals from a third-party content provider are used to help select content items in the content item campaign of the third-party content provider. The selected content items are then presented to a resource. The signals may be used to help select between content items for which there are known metrics and content items for which there are no metrics. The signals indicate trends or preferences that may indicate that one content item or type of content item is a better choice compared to other content items

Tunable Automatic Placement Finder for Third Party Content

This document describes a technique for performing tuning in automatic content slot placement process. A data processing system can send a script to a client device for automatic content slot placement. The script can be executed by the client device to obtain a chunk size report and to transmit the chunk size report to the data processing system. The data processing system can analyze data in the chunk size report and perform tuning based on the analysis. Parameters for how long to hold the main execution thread at the client device can be modified. The data processing system can also perform tuning based on device characteristics and network characteristics associated with the client device

DETECTION OF POSITION FIXED CONTENT ITEM SLOTS AND CONTROL OF CONTENT DISPLAYED THEREIN

Implementations described herein relate to detection of fixed position content item slots and control of interactions based on determining a content item slot is a fixed position content item slot, such as click protections, policy enforcement mechanism, and/or auction corrections

PARTIAL CLICK PROTECTIONS FOR ADS

Partial click protections for ads are introduced in this publication. The partial click protections for ads include applying one or more click protections to one or more specific portions of an ad unit instead of the entire ad unit. The one or more specific portions of the ad are differentiated from other portions of the ad based on various criteria. The one or more specific portions of the ad unit include specific portions of a button in the ad unit

An Unsupervised Method to Detect the Left Atrial Appendages and Classify their Morphologies

The left atrial appendage (LAA) is the site where the left atrial thrombi are most likely (90%) to develop. Despite the increasing interest that LAA has attracted over the last decade, the methods currently used to classify its morphology are mainly based on cardiologists’ judgment. Given the remarkable improvement of imaging techniques, we propose an unsupervised quantitative method that can overcome the limits of the current classification systems. The resulting classification system is objective and reproducible

Phototaxis and Impaired Motility in Adenylyl Cyclase and Cyclase Receptor Protein Mutants of Synechocystis sp. Strain PCC 6803

We have carefully characterized and reexamined the motility and phototactic responses of Synechocystis sp. adenylyl cyclase (Cya1) and catabolite activator protein (SYCRP1) mutants to different light regimens, glucose, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, and cyclic AMP. We find that contrary to earlier reports, cya1 and sycrp1 mutants are motile and phototactic but are impaired in one particular phase of phototaxis in comparison with wild-type Synechocystis sp

Rapid, Precise, and Accurate Counts of <i>Symbiodinium</i> Cells Using the Guava Flow Cytometer, and a Comparison to Other Methods

<div><p>In studies of both the establishment and breakdown of cnidarian-dinoflagellate symbiosis, it is often necessary to determine the number of <i>Symbiodinium</i> cells relative to the quantity of host tissue. Ideally, the methods used should be rapid, precise, and accurate. In this study, we systematically evaluated methods for sample preparation and storage and the counting of algal cells using the hemocytometer, a custom image-analysis program for automated counting of the fluorescent algal cells, the Coulter Counter, or the Millipore Guava flow-cytometer. We found that although other methods may have value in particular applications, for most purposes, the Guava flow cytometer provided by far the best combination of precision, accuracy, and efficient use of investigator time (due to the instrument's automated sample handling), while also allowing counts of algal numbers over a wide range and in small volumes of tissue homogenate. We also found that either of two assays of total homogenate protein provided a precise and seemingly accurate basis for normalization of algal counts to the total amount of holobiont tissue.</p></div

Summary of the properties of the counting methods.

<p>^aAt the time of counting. Note that in our standard procedure, the sample is homogenized in 500 μl and then diluted (if needed) to the optimal concentration for counting. This dilution step is not required except for samples to be counted with the Coulter Counter, for which a dilution of ~20-fold into Isoton or some comparable solution is needed. Thus, for counting with the Coulter Counter, the algal concentrations in the original homogenate must be correspondingly higher.</p><p>Summary of the properties of the counting methods.</p
