Abstract: Embodiments herein relate to, for example, a method performed by a radio network node (12) for handling communication in a wireless communication network. The radio network node (12) determines a time correlation coefficient in a channel time correlation function, and then schedules one or more resources for a UE (10) taking the time correlation coefficient into account.

Abstract: Various embodiments of the present disclosure provide a method for precoder generation. The method which may be performed by a communication device comprises: estimating slot-based channel temporal auto-correlation according to a set of channel estimates of reference signals. In accordance with an exemplary embodiment, the method further comprises: selecting a precoder for a first slot from a set of precoder candidates according to the slot-based channel temporal auto-correlation. The set of precoder candidates may be calculated by using at least part of the set of the channel estimates of the reference signals.

Abstract: A method and a device for label-free all-optical neural regulation and imaging are provided. The method stimulates a neural activity through an infrared laser pulse, and acquires an optical scattered signal caused by the neural activity by optical coherence tomography (OCT) to realize label-free all-optical neural regulation and imaging. The method specifically includes: aiming an infrared laser at a target brain region, injecting a certain time series of laser pulses, synchronously scanning and imaging the target brain region by OCT, analyzing a relative change of an OCT scattered signal before and after laser stimulation, and acquiring a brain function signal based on OCT to realize synchronous neural regulation and imaging. The method and the device enable synchronous neural regulation and imaging without causing crosstalk between the regulation and imaging channels, and without the need for injection of a contrast agent or viral transfection.

Abstract: A preparation method for semaglutide. The method comprises: producing a semaglutide resin by means of a solid-phase synthesis, producing crude semaglutide by cleavage and deprotection, producing refined semaglutide by purification and freeze-drying, comprising the solid-phase synthesis of a semaglutide 1-6 peptide fragment resin, which is cleaved and purified to serve as a first peptide fragment; and synthesizing a lysine having a sidechain group at locus 20 of semaglutide to serve as a second peptide fragment. In the method, prepared is a semaglutide loci 1-6 fully protected peptide fragment, which serves as a key starting material applied in the solid-phase synthesis of semaglutide, thus reducing the generation of D-His, D-Glu, D-Thr, D-Phe racemic impurities and +Gly impurities, reducing the difficulty of coarse product purification, increasing the purity and yield of semaglutide, reducing synthesis costs, and favoring industrialized large-scale production.

Abstract: An impression wheel assembly is disclosed to include a wheel axle fixedly supported between two brackets of a glass substrate conveying system, and an impression wheel formed of a plurality of roller units and pivotally supported on the wheel axle, each roller unit having a roller wheel frame supported on the wheel axle and an elastomeric roller wheel body mounted around the roller wheel frame.

Abstract: A ball feeder for ball serving machine includes a seat consisting of a hollow transfer frame and a shaft bear, a rotating unit mounted to one side of the seat and having a ball scoop extended from an end thereof, and a plurality of guide sections sequentially rotatably connected at an end to the shaft bearing. The guide sections may be turned about the shaft bearing in the same direction to form a nonlinearly inclined spiral ball guide path. A ball put in the top guide section automatically rolls down along the ball guide path and falls into the transfer frame to be caught by the ball scoop. When the ball scoop is turned by the rotating unit to face downward, the-ball on the ball scoop falls into a feeding mouth on a body of the ball serving machine and is automatically served.
