Opis:: At the conceptual stage of design, designers only have vague ideas of initial shapes which they gradually refine. These imprecise shapes may be specified by a set of fuzzy shape descriptors which represent the intent of a designer. It is also desirable to be able to save them in a database for future reference or for use as initial shapes for new designs. Most research on fuzzy databases has been focused on theoretical aspects while a fuzzy database is rarely seen in practice, especially in the design area. This paper aims to construct a fuzzy shape database to support shape design by integrating fuzzy data processing and fuzzy querying functions into a conventional database. A possibility-based framework is used for a fuzzy relational database model.

Opis:: An adaptive iterative receiver for layered space-time coded (LSTC) systems is proposed. The proposed receiver, based on a joint adaptive iterative detection and decoding algorithm, adaptively suppresses and cancels co-channel interference. The LMS algorithm and maximum a posteriori (MAP) algorithm are utilized in the receiver structure. A partially filtered gradient LMS (PFGLMS) algorithm is also applied to improve the convergence speed and tracking ability of the adaptive detector with a slight increase in complexity. The proposed receiver is analysed in a slow and fast Rayleigh fading channels in multiple input multiple output (MIMO) systems.

Opis:: In this research work, a six-term 3-D novel jerk chaotic system with two hyperbolic sinusoidal nonlinearities has been proposed, and its qualitative properties have been detailed. The Lyapunov exponents of the novel jerk system are obtained as L₁ = 0.07765,L₂ = 0, and L₃ = −0.87912. The Kaplan-Yorke dimension of the novel jerk system is obtained as D_KY = 2.08833. Next, an adaptive backstepping controller is designed to stabilize the novel jerk chaotic system with two unknown parameters. Moreover, an adaptive backstepping controller is designed to achieve complete chaos synchronization of the identical novel jerk chaotic systems with two unknown parameters. Finally, an electronic circuit realization of the novel jerk chaotic system using Spice is presented in detail to confirm the feasibility of the theoretical model.

Opis:: Rothmannia wittii, which is found in Binh Chau-Phuoc Buu Nature Reserve, Bung Rieng ward, Xuyen Moc District, Ba Ria-Vung Tau Province, Vietnam, is a rare species of Rubiaceae family. The present study aimed to determine the phytochemical composition and antimicrobial activity of the ethanolic extract of the R. wittii trunk. A total of 10 compounds were identified by liquid chromatography-mass spectrophotometry (LC-MS), including 1) benzene, 1-(1,5-dimethyl-4- hexenyl)-4-methyl, 2) diphenylsulfone, 3) 6β-hydroxy-10-O-acetylgenipin, 4) cinnamyl-cinnamate, 5) genipin, 6) megastigmatrienone, 7) ethyl p-methoxy-trans-cinnamate, 8) rothalazepane, 9) 1,3,6-trimethylpyrano[2,3-d ]imidazole-2,5(1H,3H)-dione, and 10) shanzhiol. The extract also exhibited an antibacterial activity against six bacterial strains: Bacillus cereus, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella typhimurium and Salmonella enteritidis, as determined via disk diffusion agar method.

Opis:: Clarifying the genetic background of the drought-tolerance trait is a crucial task that may help to improve plant performance under stress by a genetic engineering approach. dehydration-responsive element-binding protein (dREB) is a transcription factor family which modulates many stress-responsive genes. In this study, we isolated a DrEB homolog gene named ZmDrEBtv from Zea mays var. Tevang-1. Using bioinformatic tools, a number of Indels and SNPs in ZmDrEBtv sequence different from the reference accession were identified. In addition, based on deduced protein sequence similarity, ZmdREBtv was assigned to transcription factor dREB2 class as featured by a conserved dNa binding domain – aP2. The ZmDrEBtv construct under thecontrol of the rd29a promoter was transformed into a drought-sensitive maize plant, K7 line. The transgenic plants were assessed with reference to molecular and phenotypic characteristics related to the drought-tolenrance trait. The results proved that the maize plants carrying ZmDrEBtv gene showed enhanced tolerance and better performance to the water-deficit environment at different stages, compared to the wild-type plants.
