Gnetum gnemon
Opis:
Wild edible plants are often found to be rich sources of nutrients and medicinally beneficial compounds with pharmacological activities. Gnetum gnemon is a nutritionally important plant and a popular food source in parts of Assam and North-East India. Various microRNAs (miRNAs) have been recently identified in many plants; however, there are no records of identification of miRNAs in any species of Gnetum. The prediction of miRNA-target associations in G. gnemon is an important step to facilitate functional genomics studies in this species. In the present study, all known miRNAs from plants available in public domain were used to search for the conserved G. gnemon miRNA homologues in publicly accessible expressed sequence tags (ESTs) in NCBI database. An aggregate of 20 new potential miRNAs belonging to two diverse miRNA families (miR399 and miR5021) were identified through a homology-based search by following stringent filtering criteria. To investigate the potential cross-kingdom effects of the identified miRNAs, we further identified the putative target genes of G. gnemon miRNAs in human transcriptome and analyzed them against the NCBI non-redundant protein database. The KEGG analysis of the target genes indicated that these genes were involved in different metabolic pathways such as caffeine metabolism, drug metabolism, and nitrotoluene degradation. The target genes of G. gnemon miRNAs in humans were found to be associated with various disorders of both hereditary and non-hereditary origin. These results could help to shed new light on understanding of miRNA-mRNAs functional networks in this species and its potential use as a small RNA-based therapy against some human diseases.

Opis:
In this paper, the performance of an energy detector in cognitive radio, using different diversity combining techniques, is evaluated. Among many diversity combining techniques, maximal ratio combining (MRC) gives the best results but at the cost of the highest complexity. To design a simpler receiver, it is suggested to use less complex combining techniques, i.e. switched diversity, which provides one of the least complex solutions to combat fading. The paper analyzes two switched diversity schemes, switch examine combining (SEC), and switch examine combining with post examining selection (SECp). A closed form expression determining the probability of detection using MRC, SEC and SECp is derived for various numbers of branches. Detection performance with different diversity combining techniques is compared and the complexity trade-off is observed.

Opis:
Elastic anisotropy and acoustic attenuation in bulk material consisting of consolidated graphene nanoplatelets are studied. The material was prepared by spark plasma sintering, and exhibits highly anisotropic microstructure with the graphene nanoplatelets oriented perpendicular to the spark plasma sintering compression axis. The complete tensor of elastic constants is obtained using a combination of two ultrasonic methods: the through-transmission method and the resonant ultrasound spectroscopy. It is shown that the examined material exhibits very strong anisotropy both in the elasticity (the Young moduli in directions parallel to the graphene nanoplatelets and perpendicular to them differ by more than 20 times) and in the attenuation, where the dissipative effect of the internal friction in the graphene nanoplatelets combines with strong scattering losses due to the porosity. The results are compared with those obtained for ceramic-matrix/graphene nanoplatelet composites by the same ultrasonic methods.

Opis:
We show that single peridinin-chlorophyll a-protein light-harvesting complexes from dinoflagellate Amphidinium carterae placed near to silver nanoparticles show strongly enhanced fluorescence emission. Single molecule spectroscopy experiments performed at room temperature point toward an enhancement of more than an order of magnitude for optimal conditions. Irrespective of the enhancement, we observe no effect of the metal nanoparticle on the fluorescence emission energy of the complex. This result provides a way to control the optical properties of biomolecules via plasmon excitations in metal nanoparticles.
