Abstract: A method performed by a terminal in a wireless communication system is provided. The method includes receiving, from a serving base station, a radio resource control (RRC) message including a handover command to new radio (NR) cell, while performing an emergency service on long term evolution (LTE) cell. The method includes identifying whether the NR cell supports a reduced capability (RedCap) function, based on system information on the NR cell. The method includes switching an operation mode of the terminal from RedCap mode to an NR normal mode, in case that the NR cell does not support RedCap function. The method includes, while the terminal operates in the NR normal mode, performing the emergency service on the NR cell through access to the NR cell. The method includes, in response to termination of the emergency service, switching the operation mode of the terminal from NR normal mode to RedCap mode.

Abstract: Embodiments described herein provide for a non-transitory machine-readable medium storing instructions to cause one or more processors to receive, at a client device, a machine learning model from a server, detect a usage pattern for a content item, store an association between the content item and the detected usage pattern in local data, train the machine learning model using local data for the content item with the detected usage pattern to generate a trained machine learning model, generate an update for the machine learning model, privatize the update for the machine learning model, and transmit the privatized update for the machine learning model to the server.

Abstract: A downhole tool includes a fastening assembly securing one component to another component. The fastening assembly may include a threaded fastener located in an aperture of one component and a locking mechanism located in a cavity proximate the aperture. The threaded fastener may include a flange including mutually spaced holes located circumferentially within an outer periphery of the flange.

Abstract: An embodiment of the invention provides an apparatus that includes: a perpendicular magnetic recording medium including a substrate, a soft under layer above the substrate, a seed layer structure above the soft under layer, wherein the seed layer structure contains Ruthenium; and a magnetic recording layer above the seed layer structure.

Abstract: A laminated magnetic recording structure for use in perpendicular or longitudinal recording is described. A small amount of ferromagnetic coupling is added between the two magnetic layers that are sufficiently decoupled to switch independently. In one embodiment the coupling is achieved by doping the spacer layer with a ferromagnetic material. Ruthenium (Ru), which is a preferred nonmagnetic material for spacer layers with cobalt (Co) being the preferred magnetic material. The weak ferromagnetic coupling can also be achieved through the use of platinum, palladium and alloys thereof for the spacer layer without the addition of a ferromagnetic element, but alternatively they can also be doped with ferromagnetic elements. For embodiments for perpendicular recording the spacer layer further can additionally comprise oxides of one or more elements selected from the group consisting of Si, Ta, Ti, Nb, Cr, V and B.
