Three-stage turbo MBER Multiuser beamforming receiver using irregular convolutional codes
No full textBased on extrinsic information transfer (EXIT) charts, the convergence behavior of a three-stage serially concatenated multiuser beamforming receiver is presented. This system uses a linear minimum bit error rate (BER) multiuser detector as the inner module. Due to the nonrecursive nature of this inner module, a unity-rate memory-1 recursive precoder is placed in front of the channel to provide the required recursive structure. Irregular convolutional codes (IRCCs) are constructed to be used as the outer code to achieve near-capacity performance. Our simulations show that this system outperforms the traditional two-component iterative structure and is capable of significantly educing the error floor

Glycosylated cellulose derivatives with regioselective distributions of pendant glucose moieties
No full textInspired by the presence of diverse carbohydrates on the surface of biological systems, we present herein a method for the synthesis of sugar-bearing polymers derived from renewable cellulose. In this paper, novel glycosylated cellulose derivatives were successfully synthesized containing a series of subsequent reactions: (1) synthesis of cellulose derivatives with pendant hydroxyl groups via nucleophilic substitution; (2) further sequential reactions containing a novel TEMPO/[bis(acetoxy)iodo]benzene (BAIB)-mediated oxidation of pendant hydroxyl groups, Schiff base formation and reduction in one-pot reaction; and (3) thiol-ene click reaction as an efficient tool to generate cellulose derivatives with pendant glucosyl groups. Furthermore, the glucosyl groups were only linked with the C6 position of anhydroglucose units (AGUs) of cellulose. Moreover, the glycosylated cellulose derivatives could be reversibly cross-linked by 1,4-phenylenediboronic acid at pH 10 and dissociated into single polymer chains by using glucose, which allow such glycolated cellulose derivatives to be interesting responsive materials

Mannosylated fluorescent cellulose‐based glycopolymers for stable uniform nanoparticles
No full textAbstract In living organisms, carbohydrate‐protein interactions play key roles in physiological and pathological processes, which are amplified by the “glycol‐cluster effect.” In this work, we synthesized novel fluorescent cellulose derivatives bearing mannose moieties via thiol‐ene click reactions by sequentially conjugating hydrophilic mannose‐oxyethoxylpropane‐thiol (Mann‐SH) and fluorescent coumarin‐oxyhexyl‐thiol (Coum‐SH) and rhodamine B‐ethyl‐thiol (RhB‐SH) to cellulose undecenoate with terminal double bonds. The amphiphilic fluorescent cellulose derivatives were converted into nanoparticles (NPs) by dropping into low ionic strength solutions (\u0026lt;0.085 M). Obtained NPs have average sizes between 240 and 554 nm depending on the solution concentrations, exhibiting uniform size distributions (PDI values \u0026lt;0.12). These uniform NPs exhibited excellent dispersion stability even at elevated temperatures. The mannose moieties were accessible to 1,4‐benzenediboronic acid (BDBA) in NaOH aqueous solutions. Under irradiation with UV light of 320–400 nm, the fluorescence of NPs increased by the formation of open‐ring rhodamine spiroamide, which could be a promising candidate for biomedical application.A novel fluorescent cellulose derivative bearing mannose, coumarin, and rhodamine moieties is synthesized via two‐step photo‐/thermo‐initiated thiol‐ene click reactions, and stable uniform nanoparticles (NPs) are formed. The mannose moieties of NPs are accessible to 1,4‐benzenediboronic acid (BDBA) in NaOH solutions, and NPs are stabilized in strong alkaline solutions at elevated temperatures. The fluorescence intensity of NPs is increased under irradiation with UV light of 320–400 nm, which allows them to be promising candidates for biomedical applications. imageChina Scholarship Council http://dx.doi.org/10.13039/501100004543Georg‐August‐Universität Göttingen http://dx.doi.org/10.13039/501100003385Verband der Chemischen Industrie http://dx.doi.org/10.13039/100007215Fonds der Chemischen Industrie (FCI
