    • Disclosed is a process for preparing isopimaric acid, comprising the following steps: First step: dissolving thermally isomerized rosin in acetone, adding in drops a solution of isobutanolamine in acetone to form a precipitate, standing, filtering, washing with ethanol, and drying to obtain crude ammonium salt of isopimaric acid; recrystallizing the crude ammonium salt of isopimaric acid according to multi-recrystallization, and drying to obtain purified crystal of ammonium salt of isopimaric acid; Second step: dissolving the purified crystal of ammonium salt of isopimaric acid obtained in the first step in ether, adding hydrochloric acid in portions until the crystal of ammonium salt of isopimaric acid disappears, removing a water layer and washing the ether layer with water to neutral, evaporating the ether, dissolving the residue in acetone, adding water slowly into the solution dropwise until crystals cease to grow, then filtering and drying to obtain purified isopimaric acid.
    • 公开了一种制备异海松酸的方法,包括以下步骤:第一步:将热异构松香溶解在丙酮中,滴加异丁醇胺的丙酮溶液形成沉淀,静置,过滤,用乙醇洗涤,并干燥得到 异海松酸的粗铵盐; 根据多重结晶重结晶异海松酸的粗铵盐,干燥,得到异海松酸铵盐的纯化结晶; 第二步:将纯化的第一步获得的异海松酸铵盐的结晶溶解在乙醚中,分几次加入盐酸,直到异海松酸的铵盐结晶消失,去除水层,用水洗涤乙醚层至中性 蒸发乙醚,将残余物溶解在丙酮中,慢慢加入水中直到晶体停止生长,然后过滤并干燥,得到纯化的异海松酸。

    • The present disclosure discloses a method for paging an emergency service user. When a mobility management unit is configured to support the paging optimization in a core network, the mobility management unit does not perform paging optimization when a UE has an emergency bearer service. That is to say, a paging message is sent to all base stations (including the CSG-mode home base station that does not authorize the UE) in the paging tracking list registered by the UE. A core network gateway can notify the mobility management unit of whether the UE has an emergency bearer service. Alternatively, the mobility management unit configured to use the paging optimization, after learning that the service data is to be sent to the UE, checks the current service type of the UE to determine whether the UE has an emergency bearer service. Accordingly, the present disclosure further discloses a system for paging an emergency service user. The present disclosure solves the problem that the mobility management unit and home base station gateway using the paging optimization cannot page the UE which uses the emergency service, so as to increase the success rate of establishing communications and improve the user experience.
    • 本公开公开了一种用于寻呼紧急服务用户的方法。 当移动性管理单元被配置为支持核心网络中的寻呼优化时,当UE具有紧急承载服务时,移动性管理单元不执行寻呼优化。 也就是说,在由UE登记的寻呼跟踪列表中,向所有基站(包括不授权UE的CSG模式家庭基站)发送寻呼消息。 核心网关可以通知移动性管理单元UE是否具有紧急承载业务。 或者,移动性管理单元被配置为在学习到要向UE发送业务数据之后使用寻呼优化来检查UE的当前业务类型,以确定UE是否具有紧急承载业务。 因此,本公开进一步公开了一种用于寻呼紧急服务用户的系统。 本公开解决了使用寻呼优化的移动性管理单元和家庭基站网关不能寻呼使用紧急服务的UE,从而提高建立通信的成功率并提高用户体验的问题。

    • Methods, systems, and computer programs for encoding and decoding image are described. In some aspects, an input data block and a prediction data block are accessed. A projection factor is generated based on a projection of the input data block onto the prediction data block. A scaled prediction data block is generated by multiplying the projection factor by the prediction data block. A residual data block is generated based on a difference between the input data block and the scaled prediction data block. In some aspects, a prediction data block, a residual data block, and a projection factor associated with the residual data block are accessed. A scaled prediction data block is generated by multiplying the projection factor by the prediction data block. An output data block is generated by summing the residual data block and the scaled prediction data block.
