A Coherent PMI Estimation Scheme for Double Codebook
The double codebook structures are proposed and applied in LTE-advanced, which can track both longterm and short-term channel state information. In traditional incoherent estimation, precoding matrix indicators (PMI) estimation is performed on each individual subcarrier and some form of averaging procedure then follows to combine the results from individual narrow-band processing. As a result, …

Highly enhanced capacitance of CuO nanosheets by formation of CuO/SWCNT netwo…
Abstract. A series of uniform composite networks consisting of CuO nanosheets (NSs)/single-wall carbon nanotubes (SWCNT) were fabricated through a facile and green method with the aid of electrostatic interaction in aqueous solution. The capacitance was investigated by using various electrochemical methods including cyclic voltammetry (CV), constant-current galvanostatic charge/discharge cu…

Fabrication of robust honeycomb polymer films: A facile photochemical cross-l…
Abstract. Highly ordered honeycomb films are prepared by breath-figure method using an amphiphilic diblock copolymer of polystyrene-block-polyacrylic acid (PS-b-PAA). By simply cross-linking PS matrix via deep ultraviolet (UV) irradiation, both the solvent and thermal stability of the porous films was significantly improved while retaining the three-dimensional (3D) structures. The film sur…

Effect of biochar amendment on soil-silicon availability and rice uptake
Rice growth and its resistance to pests had been often constrained by soil-silicon (Si) availability.The purpose of this study was to assess the potential of biochar soil amendment (BSA) to improve Si availability in paddy soils. A cross-site field trail with BSA was conducted in six locations with different climatic and crop-production conditions across S China. Plant-available Si content befo…
