Abstract: An apparatus for use in a base station includes processing circuitry to perform SRS sequence de-mapping of OFDM symbols to generate a de-mapped sequence. The OFDM symbols correspond to a UL stream with SRS transmissions from a plurality of UEs. A first least square (LS) estimation is performed based on the de-mapped sequence to obtain a first LS sequence. A time domain (TD) transformation and a frequency domain (FD) transformation is applied to the first LS sequence to generate a first partial SRS channel estimate sequence. A second LS estimation is performed based on the de-mapped sequence to obtain a second LS sequence. The second LS sequence is filtered to generate a second partial SRS channel estimate sequence. A full SRS channel estimate sequence corresponding to the SRS transmissions is generated based on the first and second partial SRS channel estimate sequences.

Abstract: Implementations relate to a system for hosting independent content items anchored to another online resource. The independent content items are themselves online resources. Implementations also relate to enhancing search results by incorporating independent content items anchored to a resource identified in the search result page. An example method involves identifying resources to be included in search results for a query, determining that independent content items are associated with a resource, and adding an independent content item summary control to the search result for the resource. This control enables users to access an independent content feed interface for further exploration of the independent content items anchored to the resource. The search result page, enriched with these independent content item overview, is then delivered to the user's device.

Abstract: The present disclosure provides a method for two-phase partitioning production of a medium-chain fatty acid (MCFA) by dry anaerobic digestion. In the present disclosure, due to a slow heat transfer of the dry anaerobic digestion, a same dry anaerobic digestion device is naturally divided into two phases, and the MCFA is synthesized while producing electron acceptors and electron donors in the same dry anaerobic digestion device. Meanwhile, the dry anaerobic digestion device is provided with a high-efficiency decomposing microbial inoculant on an upper part and inoculated with sludge having a carbon chain extension function on a lower part. In this way, a material residence time is regulated, and cycles of hydrolytic acidification and carbon chain extension are shortened, thereby achieving the high-value conversion of agricultural waste while increasing a conversion rate of organic acids in the dry anaerobic digestion.

Abstract: Disclosed is a method for establishing an active distribution network planning model considering location and capacity determination of an electric vehicle charging station. In terms of location and capacity determination of electric vehicle charging stations, a traffic flow of electric vehicles is converted into a charging demand flowing in a traffic network, and an electric vehicle traffic network model is established based on an M/M/s queuing model and a flow capturing location model in the traffic field. A distributed generation (including wind power and photovoltaic) and load model is established, based on a time series method. An energy storage element model in a power distribution network is established based on an idea of equivalent load. A nested planning model is established by taking economy and reliability of a power distribution network and a maximum traffic flow intercepted by the electric vehicle charging stations as objectives.
