    Joint optimization of dispersion matrix and 3D constellation for STSK system based on improved genetic algorithm by Xiaoping JIN, Jiayu LIU, Chen JIANG, Qiang GUO

    Published 2021-09-01
    “…Space-time shift keying (STSK) is a modulation scheme used in multi-input multi-output (MIMO) communication systems.It uses a pre-designed dispersion matrix set (DMS) to realize the flexible design of the system between multiplexing and diversity.An improved genetic algorithm (GA) was proposed to assist the joint optimization of DMS and 3D constellations, that is, the DMS and 3D constellations were jointly coded as the chromosome of GA , and the coding gain corresponding to the rank and determinant criterion was adopted as the overall fitness value.Through efficient selection and improved mutation and crossover strategies, DMS and 3D constellations with low bit error rate (BER) can be obtained.At the same time, the symmetry of the 3D constellation was used to greatly reduce the computational complexity of according to the fitness value the coding gain.The theoretical average paired error probability (ABEP) of the 3D STSK scheme was deducted.The simulation results show that, compared with the traditional GA and random search schemes, the improved GA proposed can significantly reduce the complexity of system implementation while ensuring BER performance.…”

    Trichoscopy in Unveiling the Triad of Netherton Syndrome by H Bangaru, D Ashwini

    Published 2025-01-01
    “…Netherton syndrome (NS) is a rare autosomal recessive disorder characterized by the triad of congenital ichthyosiform erythroderma or ichthyosis linearis circumflexa (ILC), hair shaft abnormalities, and atopic diathesis (elevated serum IgE) caused by mutations in serine protease-inhibitor (SPINK5) gene located on chromosome 5q31–32. Here, we present a case of a 16-year-old female born to second-degree consanguineous marriage who presented with a history of atopy, generalized xerosis, plaques with serpiginous borders, and double-edged scales over the trunk, upper and lower limbs, lichenification in flexures, sparse eyelashes, and eyebrows predominantly over lateral half was noted. …”

    Cloning a Chloroplast Genome in Saccharomyces cerevisiae and Escherichia coli by Emma Walker, Bogumil Karas

    Published 2025-01-01
    “…Prior to our work, the chloroplast genomes of Chlamydomonas reinhardtii (204 kb) and Zea mays (140 kb) had been cloned using bacterial and yeast artificial chromosome (BAC/YAC) libraries, respectively. These methods lack design flexibility as they are reliant upon the random capture of genomic fragments during BAC/YAC library creation; additionally, both demonstrated a low efficiency (≤ 10%) for correct assembly of the genome in yeast. …”
