Abstract: Techniques are disclosed for tuning hyperparameters of a model. Datasets are obtained for training the model and metrics are selected for evaluating performance of the model. Each metric is assigned a weight specifying an importance to the performance of the model. A function is created that measures performance based on the weighted metrics. Hyperparameters are tuned to optimize the model performance. Tuning the hyperparameters includes: (i) training the model that is configured based on a current values for the hyperparameters; (ii) evaluating a performance of the model using the function; (iii) determining whether the model is optimized for the metrics; (iv) in response to the model not being optimized, searching for a new values for the hyperparameters, reconfiguring the model with the new values, and repeating steps (i)-(iii) using the reconfigured model; and (v) in response to the model being optimized for the metrics, providing a trained model.

Abstract: A microelectronic device with a trench structure is formed by forming a trench in a substrate, forming a seed layer in the trench, the seed layer including an amorphous dielectric material; and forming semi-amorphous polysilicon on the amorphous dielectric material. The semi-amorphous polysilicon has amorphous silicon regions separated by polycrystalline silicon. Subsequent thermal processes used in fabrication of the microelectronic device may convert the semi-amorphous polysilicon in the trench to a polysilicon core. In one aspect, the seed layer may be formed on sidewalls of the trench, contacting the substrate. In another aspect, a polysilicon outer layer may be formed in the trench before forming the seed layer, and the seed layer may be formed on the polysilicon layer.

Abstract: The provision of fog services may be coordinated by a fog leader adapted to track capabilities and resources available at other fog nodes, and to receive and process requests and policies from entities seeking fog services. For example, the fog leader may divide tasks among several fog nodes according to the capabilities and resources available at various nodes, and do so in a way that is transparent to the requestor and the fog nodes providing the service. The fog leader may request the reservation of capabilities and resources, and confirm and cancel such reservations. Fog services policies may include, for example, periods of time during which capabilities and resources should be reserved.

Abstract: The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface (MFS), a trailing shield at the MFS, and a heavy metal layer disposed between the main pole and the trailing shield at the MFS. Spin-orbit torque (SOT) is generated from the heavy metal layer and transferred to a surface of the main pole as a current passes through the heavy metal layer in a cross-track direction. The SOT executes a torque on the surface magnetization of the main pole, which reduces the magnetic flux shunting from the main pole to the trailing shield. With the reduced magnetic flux shunting from the main pole to the trailing shield, write-ability is improved.

Abstract: Current discovery mechanisms lack capabilities, such as capabilities related to permissions associated with a given registrant for example. In an example embodiment, a registrant of a service layer can communicate with a network node that hosts the service layer. The network node may receive a discovery request for a resource from the registrant. The discovery may request include various context. For example, the context of the discovery request may be indicative of an operation that the registrant intends to perform on the resource, a role that the registrant intends to assume if the registrant accesses the resource, a location in which the registrant intends to access the resource, or a subscription plan that the registrant intends to use if the registrant accesses the resource. Based on the context of the discovery request, the network node may determine whether one or more resources at the service layer satisfy the discovery request.

Abstract: The present disclosure generally relates to spin-orbital torque (SOT) differential reader designs. The SOT differential reader is a multi-terminal device that comprises a first shield, a first spin hall effect layer, a first free layer, a gap layer, a second spin hall effect layer, a second free layer, and a second shield. The gap layer is disposed between the first spin hall effect layer and the second spin hall effect layer. Electrical lead connections are located about the first spin hall effect layer, the second spin hall effect layer, the gap layer, the first shield, and/or the second shield. The electrical lead connections facilitate the flow of current and/or voltage from a negative lead to a positive lead. The positioning of the electrical lead connections and the positioning of the SOT differential layers improves reader resolution without decreasing the shield-to-shield spacing (i.e., read-gap).
