Abstract: Techniques are described for predicting groundwater for a locale, which is a subregion of a geographic region for which measurements of water storage are available at a coarse level. In a method, in response to receiving an input locale, a prediction of groundwater level for the input locale is provided.

The machine learning model uses a plurality of parameters, which are weighted during a training phase of the machine learning model, and water storage measurements for a geographic region that encompasses the locale, the geographic region being larger than the locale, and wherein a resolution of the water storage measurements is downscaled. The prediction of groundwater level is outputted for the input locale.

Abstract: A method for fabricating a three-dimensional (3D) static random-access memory (SRAM) architecture using catalyst influenced chemical etching (CICE). Utilizing CICE, semiconductor fins can be etched with no etch taper, smooth sidewalls and no maximum height limitation.

Abstract: Some embodiments provide a method for detecting a failure of a layer 2 (L2) bump-in-the-wire service at a device. In some embodiments, the device sends heartbeat signals to a second device connected to L2 service nodes in order to detect failure of the L2 service (e.g., a failure of all the service nodes). In some embodiments, the heartbeat signals are unidirectional heartbeat signals (e.g., a unidirectional bidirectional-forwarding-detection (BFD) session) sent from each device to the other. The heartbeat signals, in some embodiments, use a broadcast MAC address in order to reach the current active L2 service node in the case of a failover (i.e., an active service node failing and a standby service node becoming the new active service node). The unidirectional heartbeat signals are also used, in some embodiments, to decrease the time between a failover and data messages being forwarded to the new active service node.

Abstract: A tracking device broadcasts beacon signals that are separated in time by broadcast intervals. The tracking device determines the broadcast intervals based on a behavior model. The behavior model specifies one or more conditions, such as times of day within a 24-hour day, and associates a usage probability with each condition. A higher usage probability causes the tracking device to broadcast beacon signals at shorter broadcast intervals. A mobile device in communication with the tracking device can reconfigure the behavior model, either by modifying portions of the behavior model or by replacing the behavior model with a different behavior model. This allows the behavior model to adapt to different circumstances, such as different usage patterns during weekdays, weekends, and vacations.

Abstract: Some embodiments provide novel methods for providing different types of services for a logical network associated with an edge forwarding element acting between the logical network and an external network. The edge forwarding element receives data messages for forwarding and performs a service classification operation to select a set of services of a particular type for the data message. The particular type of service is one of multiple types of services that use different transport mechanisms to forward the data to a set of service nodes (e.g., service virtual machines, or service appliances, etc.) that provide the service. The edge forwarding element receives the data message after the selected set of services has been performed and performs a forwarding operation to forward the data message. In some embodiments, the method is also performed by edge forwarding elements that are at the edges of logical network segments within the logical network.

Abstract: A method for bonding with precision alignment. A first bonding surface is bonded with a second bonding surface, where features on the first and second bonding surfaces are precisely overlaid during the bonding. An etch is then performed on the first and/or second bonding surfaces to create recesses in the first and/or second bonding surfaces. Precision alignment of the first and second bonding surfaces is then enabled by a volatile fluid deployed between the first and second bonding surfaces, where the recesses enable removal of the volatile fluid from a bonding interface during and after the bonding.
