Abstract: This document describes systems and techniques for improving the integrity and protecting the security of information in content selection and distribution. In one aspect, a method includes receiving, by a first server of a secure multi-party computation (MPC) system and from an application on a client device, a request for a selection value. In response to receiving the request, the first server conducts, in collaboration with a second server of the secure MPC system, a privacy-preserving selection process and a counterfactual selection process. The first server transmits a selection result defining the first winning selection value from the privacy-preserving selection process and the second winning selection value from the counterfactual selection process and receives, from the application on the client device, a notification indicating that a digital component corresponding to the winning selection value from the privacy-preserving selection process was presented at the client device.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, a terminal device receives, from a network device, a first physical random access channel (PRACH) repetition pattern. The PRACH repetition pattern comprises a first list of resource sets. If none of power of the resource sets in the first PRACH repetition pattern exceeds a first power threshold, the terminal device determines whether power of at least one resource set in the first PRACH repetition pattern exceeds a second power threshold. The terminal device performs repetitions for at least one PRACH based on the determination. In this way, the PRACH repetition can be performed more sufficiently.

Abstract: A data storage device includes a controller, one or more memory devices and one or more passive components encapsulated in a single package. The controller, the memory devices and the passive components are directly mounted to a printed circuit board (PCB) of the data storage device. A position of the controller with respect to the one or more memory devices enables the data storage device to use shorter signal traces. Shorter signal traces leads to improved read and/or write speeds of the data storage device along with other benefits.

Abstract: A computer system is configured to receive a request for allocation of a resource within a cloud environment that includes multiple regions. The computer system then identifies multiple subscriptions in each of the multiple regions. Each subscription is associated with a quota and a usage amount. For each region, the computer system computes a total quota indicating a sum of quotas of the multiple subscriptions and a total usage amount indicating a sum of used amount of the multiple subscriptions in the corresponding region, and computes a total usage ratio based on the total usage amount and the total quota. The computer system then selects a particular region in the multiple regions based on the total usage ratios, and selects a particular subscription in the multiple subscriptions in the particular region based on at least one rule that balances usage of different types of resources.

Abstract: A user equipment (UE) may generate first HARQ-ACK information bits based on a first PDSCH and second HARQ-ACK information bits based on a second PDSCH. The UE may determine a first slot for an expected PUCCH transmission with the first HARQ-ACK information bits. When the UE is configured for deferring HARQ-ACK for the first PDSCH and when the first slot is unavailable for the expected PUCCH transmission, the UE may determine an earliest second slot that is available. The UE may also determine a third slot for an expected PUCCH transmission with the second HARQ-ACK information bits assigned for the second PDSCH. The resource assigned for transmission of the first HARQ-ACK information bits is used to verify the order for the first and second HARQ-ACK transmissions regardless of whether the first slot is unavailable and the second earliest slot is used for transmission of the first HARQ-ACK information bits.

Abstract: Systems and methods are disclosed for protecting data. A device requesting access to the data is required to correctly respond to a challenge embedded in the data provided responsive to a request for the data. If the device that receives the data is able to generate the correct response to the challenge, the device can be validated as the device that was intended to receive the data. When the device is able to generate the correct response to the challenge, the correct response can indicate that the requested data is being used as intended. That is, the challenge can ensure that the context specified in the request, which was deemed an appropriate environment for use of the data by the server that triggered distribution of the data responsive to the request, is, in fact, the context in which the data is actually going to be used.

In response to determining that at least the threshold number of measurement data elements having the same group identifier have been received, the network data is decrypted using the group member keys in the received measurement data elements.
