Abstract: A communications device inputs channel state information to an artificial neural network. The communications device predicts weather conditions with the artificial neural network based on the channel state information. The communications device further adjusts communications based on the predicted weather conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a dynamic indication to switch from a modulation and coding scheme (MCS) table to a new MCS table. The UE may transmit, to the base station, one or more uplink communications that use a transmit waveform type associated with the new MCS table. Numerous other aspects are provided.

Abstract: A steerable biopsy device comprises an outer sheath comprising a sheath body having a proximal sheath section and a distal sheath section. The outer sheath further comprises a distal sheath tip and a sheath lumen terminating at a distal port in the distal sheath tip. The biopsy device further comprises a biopsy needle integrated with the sheath body. The biopsy needle is slidably disposed in the sheath lumen. The biopsy needle comprises a needle shaft and a distal needle tip configured for being displaced between a stored position within the sheath lumen and a deployed position outside of the distal port of the distal sheath tip. The biopsy device further comprises an articulation control actuator configured for articulating the distal sheath section, and a needle actuator configured for distally advancing the distal needle tip from the stored position to the deployed position.

Abstract: A golf bag having retractable wheels and handle including a golf bag having a peripheral shell extending downwardly therefrom. The peripheral shell has an open lower end. A pair of wheels are retractably disposed within the peripheral shell of the golf bag in a closed orientation. A handle portion is provided having a T-shaped configuration defined by a lower vertical segment and an upper horizontal segment. The lower vertical segment is coupled with respect to the pair of wheels. A spring-locking mechanism selectively locks the handle portion with respect to the pair of wheels.
