Appl. No.:

09/208827

Inventors:

Ying Luo - Los Altos CA
Pei Wen Yu - Burlingame CA
James Lorens - Portola Valley CA

Assignee:

Rigel Pharmaceuticlas, Inc. - So. San Francisco CA

International Classification:

C12P 2102

US Classification:

435 691, 435466, 435477, 435483

Abstract:

The invention provides shuttle vectors, and methods of using shuttle vectors, capable of expression in, at least, a mammalian cell. Furthermore, the shuttle vectors are capable of replication in at least yeast, and optionally, bacterial cells. Also provided is a method wherein yeast are transformed with a shuttle vector as provided herein. Heterologous nucleic acids flanked by 5â and 3â ends identical to a homologous recombination site within the shuttle vector are introduced to the transformed yeast and allowed to homologously recombine with the shuttle vector such that they are inserted into the vector by the yeast organism. The shuttle vector is then recovered and transferred to a mammalian cell for expression.

Abstract:

The invention provides shuttle vectors, and methods of using shuttle vectors, capable of expression in, at least, a mammalian cell. Furthermore, the shuttle vectors are capable of replication in at least yeast, and optionally, bacterial cells. Also provided is a method wherein yeast are transformed with a shuttle vector as provided herein. Heterologous nucleic acids flanked by 5' and 3' ends identical to a homologous recombination site within the shuttle vector are introduced to the transformed yeast and allowed to homologously recombine with the shuttle vector such that they are inserted into the vector by the yeast organism. The shuttle vector is then recovered and transferred to a mammalian cell for expression.

International Classification:

G06K 9/20
G06K 9/00
G06T 7/70

Abstract:

To improve the accuracy and efficiency of object detection through computer digital image analysis, the detection of some objects can inform the sub-portion of the digital image to which subsequent computer digital image analysis is directed to detect other objects. In such a manner object detection can be made more efficient by limiting the image area of a digital image that is analyzed. Such efficiencies can represent both computational efficiencies and communicational efficiencies arising due to the smaller quantity of digital image data that is analyzed. Additionally, the detection of some objects can render the detection of other objects more accurate by adjusting confidence thresholds based on the detection of those related objects. Relationships between objects can be utilized to inform both the image area on which subsequent object detection is performed and the confidence level of such subsequent object detection.

International Classification:

Abstract:

Techniques for optimizing content item delivery for installations or activations of a mobile application are provided. In one technique, a machine-learned model is trained based on multiple training instances that individually indicate whether an entity performed a particular action relative to a mobile application. In response to receiving a content item request from a third-party content delivery exchange, it is determined whether a client device that initiated the content item request has activated a particular application. In response to determining that the client device has not activated the particular application, multiple feature values of the content item request are identified. Based on inputting the feature values into the model, a score is generated that indicates a likelihood that an entity of the client device will perform the particular action relative to the particular application. Based on the score, a content item is transmitted over a network to the client device.
