The method may further include determining whether an HCE value among the HCE values fails to satisfy a predetermined criterion.

Abstract: The method of making a wall-coated open tubular capillary column with a poly benzyl stationary phase is a method of preparing a capillary column for gas chromatography. An inner wall of a fused silica capillary column is cleaned and then rinsed with a sodium hydroxide solution. The fused silica capillary column is flushed with isopropanol to form a pre-treated capillary column, and the pre-treated capillary column is loaded with a mixture of phenyl tri-methoxy silane and alcohol. The loaded pre-treated capillary column is heated to form a treated capillary column, which is then washed. A thin layer of a poly benzyl stationary phase is then coated on the inner wall through condensation polymerization of benzyl chloride monomers with a Lewis acid catalyst in a non-polar solvent.

Abstract: Methods, systems, and devices for wireless communication are described to support concurrent beam pair link (BPL) measurement and reporting on a subband basis. A base station may configure a user equipment (UE) to measure one or more wideband reference signals transmitted by the base station for each of a set of BPLs, for joint BPL selection, and the UE may receive the wideband reference signals. The UE may perform measurements for each of the set BPLs at a subband level and may report signal qualities for the different BPL combinations at a subband level. For example, the UE may measure different combinations of transmit beams and receive beams (e.g., may measure different BPLs) over multiple antenna panels, on a per-subband basis. The UE may report information based on the measurements that may support selection of BPLs for multi-panel and multi-beam operation for one or more subbands.
