Aspects of the present disclosure implement techniques to allow a base station to transmit a “short-page” message (e.g., paging indicators) to one or more UEs. The short-page message may be decoded by all UEs in the paging cycle and identifies a subset of UEs from the full set of UEs that are paged by the base station. Upon decoding the short page transmitted by the base station, the UE may respond with a “short-page response” to the base station on a transmit beam that offers best signal quality (e.g., low signal-to-noise ratio, transmit power, etc.). Thus, in some examples, the UE, in response to receiving a short paging message, may provide feedback to the base station such that the base station may select a transmit beam for transmission for a subsequent message (and other communications). |

Fixed HS-DSCH or E-DCH allocation for VoIP (or HS-DSCH without HS-SCCH/E-DCH without E-DPCCH)
In order to reduce the HS-SCCH overhead, a fixed time allocation approach could be used. In that case, the scheduling time of each VoIP user is semi-static and thus there is no need to transmit e.g. HS-SCCH toward the UE for the initial transmissions, if the UE knows when to receive data on the HS-DSCH and what transport format is used. There are at least two ways of implementing this: 1) HS-SCCH/E-DPCCH signalling to indicate parameters of a first transmission, with subsequent transmissions using the same parameters (and HS-SCCH/E-DPCCH always sent when changes needed), or 2) fixed allocation, RRC signalling used to allocate users and tell the default transport parameters. |

The present disclosure relates to a solid-state imaging element with which electric power consumption can be reduced, a method for operating the solid-state imaging element, an imaging device, and electronic equipment. After a signal output is outputted from a driver in an Nth row according to a selection signal from a vertical scanning unit, switchover is performed to transmit a signal output from a driver in an (N+1) row.

Determining for an optimal timeout value to minimize downtime for nodes in a network-accessible server set
Methods, systems, and computer program products are described herein for minimizing the downtime for nodes in a network-accessible server set. The downtime may be minimized by determining an optimal timeout value for which a fabric controller waits to perform a recovery action. The optimal timeout value may be determined for each cluster in the network-accessible server set. The optimal timeout value advantageously reduces the overall downtime for customer workloads running on a node for which contact has been lost. The optimal timeout value for each cluster may be based on a predictive model based on the observed historical patterns of the nodes within that cluster. In the event that an optimal timeout value is not determined for a particular cluster (e.g., due to a lack of observed historical patterns), the fabric controller may fall back to a less than optimal timeout value. |

The step of cutting the workpiece includes the step of cutting the workpiece while supplying a cutting fluid containing an organic acid and an oxidizing agent to the workpiece. |

Semiconductor device and semiconductor device fabrication method
A multilayer wiring in a semiconductor device includes a first lower wiring formed in a first insulating layer, a via which is formed in a second insulating layer over the first insulating layer and which is connected to the first lower wiring, and an upper wiring connected to the via. The upper wiring has an outer edge at which a nick portion is formed beside a portion of the upper wiring to which the via is connected. The formation of the nick portion at the outer edge of the upper wiring prevents the via from enlarging. |

Substrate treatment method and substrate treatment device
In parallel with a lower-side scrub cleaning step where a brush is contacted with a lower surface inclined portion of a substrate, a center-side spray cleaning step is performed where a collision position of liquid droplets with respect to an upper surface of the substrate is moved between the center of the substrate and the middle of the substrate while the liquid droplets collide with the upper surface of the substrate. Thereafter, in parallel with an upper-side scrub cleaning step where the brush is contacted with an upper surface inclined portion of the substrate, an outer circumference-side spray cleaning step is performed where the collision position of the liquid droplets with respect to the upper surface of the substrate is moved between the middle of the substrate and the outer circumference of the substrate while the liquid droplets collide with the upper surface of the substrate. |
