Abstract: According to a magnetic core considering the skin effect of magnetic flux and a design method thereof, with a cross-section of a magnetic core through which magnetic flux flows as a reference surface, the shape of the cross-section of the magnetic core is designed according to the electromagnetic characteristics, temperature characteristics, magnetic flux amplitude and operating frequency of the magnetic core, and a closed or discontinuous air path is formed inside the magnetic core by stretching the reference surface along the path of the magnetic flux, thereby forming a magnetic core having a duct structure. When a high-frequency magnetic flux is introduced into the magnetic core, the magnetic core considering the skin effect of magnetic flux and the design method thereof can reduce the weight of the magnetic core, reduce the power loss and temperature rise of the magnetic core, and suppress the skin effect of the magnetic core.

Abstract: A BIOS error locating method and apparatus, a device, and a storage medium are provided. The method includes: acquiring one or more MAP files which are generated during a compilation process of a BIOS and used for recording an entry address offset of each function; recording a base address of each function module after the BIOS is started, so as to obtain a base address log file; in response to occurrence of an EXCEPTION error during an execution process of the BIOS, executing an Exception handling function, so as to determine, according to the base address log file and the one or more MAP files, a target function that results in the EXCEPTION error; and recording a name of the target function in a serial log, and sending the serial log to a BMC.

Abstract: An oil-in-water emulsion and a method of preparing the oil-in-water emulsion. The oil-in-water emulsion includes a siloxane mixture, a natural oil, an emulsifier and water.

Abstract: Techniques are provided for automatically tuning a parameter in a layered model framework. One or more machine learning techniques are used to train multiple versions of a first model that includes a first version and a second version. A second model is stored that includes a parameter and accepts, as input, output from the first model. Multiple parameter values of the parameter are tested when processing content requests using the first and second versions of the first model. A strict subset of the plurality of parameter values are selected for the parameter of the second model, such that processing a first subset of the content requests using the first version of the first model results in a first value of a particular metric that matches a second value of the particular metric resulting from processing a second subset of the content requests using the second version of the first model.

Abstract: Techniques for using a machine-learned model to personalize content item density. In one technique, an entity that is associated with a content request is identified. Multiple sets of content items are identified that includes content items of different types. A first position of a first slot is determined in a content item feed that comprises multiple slots. A second position of a previous content item is determined, in the content item feed, that is of a first type. A difference between the first position and the second position is determined. Based on the difference, a gap sensitivity value that is associated with the entity and is different than the difference is determined. Based on the gap sensitivity value, a content item from the multiple sets of content items is selected and inserted into the first slot. The content item feed is transmitted to a computing device to be presented thereon.

Abstract: Techniques for selectively transmitting electronic notifications using machine learning techniques based on entity selection history are provided. In one technique, a candidate notification is identified for a target entity. An entity selection rate of the candidate notification by the target entity is determined. Based on the candidate notification, determining a probability of the target entity visiting a target online system. Based on online history of the target entity, a measure of downstream interaction by the target entity relative to one or more online systems is determined. Based on the entity selection rate, the probability, and the measure of downstream interaction by the target entity, a score for the candidate notification is generated. Based on the score, it is determined whether data about the candidate notification is to be transmitted over a computer network to a computing device of the target entity.

Abstract: An aided translation method and a device thereof, belonging to the field of Human-Computer Interaction. The method comprises the steps of: obtaining a destination from the itinerary information of a user; translating the pre-stored personal form-filling information of the user from a source language to a target language when the language of the destination is different from that of the user's usual place of residence, wherein, the target language is the language of the destination; and displaying the personal form-filling information in the target language. The method and a device solve the problem of users in filling in the arrival/departure card caused by unfamiliarity with foreign languages and the form-filling formats, and achieve an effect that users can fill in the arrival/departure card easily by reference to the personal form-filling information displayed in the target language.
