Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The service can provide the capability to execute user code in response to events triggered on various event sources and initiate execution of other control functions to improve the code execution environment in response to detecting errors or unexpected execution results. The service may maintain or communicate with a separate storage area for storing code execution requests that were not successfully processed by the service. Requests stored in such a storage area may subsequently be re-processed by the service.

Abstract: Approaches introduce a pre-processing and post-processing framework to a neural network-based approach to identify items represented in an image. For example, a classifier that is trained on several categories can be provided. An image that includes a representation of an item of interest is obtained. Rotated versions of the image are generated and each of a subset of the rotated images is analyzed to determine a probability that a respective image includes an instance of a particular category. The probabilities can be used to determine a probability distribution of output category data, and the data can be analyzed to select an image of the rotated versions of the image. Thereafter, a categorization tree can then be utilized, whereby for the item of interest represented the image, the category of the item can be determined. The determined category can be provided to an item retrieval algorithm to determine primary content for the item of interest.

The modified oligonucleotide compositions include one or more modified groups that increase the Tm of the resultant oligonucleotide composition.

Abstract: Methods for doping an absorbent layer of a p-n heterojunction in a thin film photovoltaic device are provided. The method can include depositing a window layer on a transparent substrate, where the window layer includes at least one dopant (e.g,. copper). A p-n heterojunction can be formed on the window layer, with the p-n heterojunction including a photovoltaic material (e.g., cadmium telluride) in an absorber layer. The dopant can then be diffused from the window layer into the absorber layer (e.g., via annealing).

Abstract: An apparatus may, for example, include a first lever pivoting about a first axis. The apparatus may also include a second lever mounted with the first lever, pivoting about a second axis, and biased to a first position.

Abstract: A system for monitoring incoming code execution requests and scheduling the corresponding code executions is provided. The system may be configured to maintain a plurality of virtual machine instances. The system may be further configured to determine whether at least some of the incoming code execution requests exhibit periodicity, and cause a reduced amount of idle compute capacity to be maintained on the virtual compute system. The system may be further configured to cause additional compute capacity to be added shortly before code execution requests are expected to be received.

Abstract: Methods and systems for forming a scribe line in a thin film stack on an inner surface of a thin film photovoltaic superstrate are provided via the use of a cleaning laser beam and a scribing laser beam. The cleaning laser beam is focused directly onto the exposed surface of the superstrate such that the cleaning laser beam removes debris from the exposed surface of the superstrate, and the scribing laser beam is focused through the exposed surface of the superstrate and onto the thin film stack such that the scribing laser beam passes through the superstrate to form a scribe within the thin film stack on the inner surface of the superstrate. The method and system can further utilize a conveyor to transport the superstrate in a machine direction to move the superstrate past the cleaning laser source and the scribing laser source.
