Termites are highly abundant and vital insects that directly indirectly influence local soils. The present study investigated the morphological molecular phylogenetics of termite species collected from fields in southern Haryana, India, 2020 to 2021. Samples were subjected integrated systematic analyses, taking into account mandible features soldiers for systematics 16S rRNA gene-based phylogen...

image denoising by block matching and threedimensionaltransform filtering (bm3d) is a two steps state-ofthe-art algorithm that uses the redundancy of similar blocks innoisy image for removing noise. similar blocks which can havesome overlap are found by a block matching method and groupedto make 3-d blocks for 3-d transform filtering. in this paper wepropose a new block grouping algorithm in th...

Phylogenetic relationships among the Eumeces schneiderii princeps and Eumeces schneiderii pavimentatus investigated using 509 bp partial sequences of 16S mitochondrial gene. Analyses were done by maximum-likelihood (RAxML) criteria on 52 specimens from over 20 geographically distinct localities. Our molecular results proposed two well-supported major clades by their phylogenetic positions, gene...

aphids are among important agricultural pests. the pest's evolutionary tendency towards a loss of taxonomically useful characteristics, as well as morphological plasticity due to host type and as a result of environmental factors, make a morphological identification of aphids difficult, whereas exact identification is indispensable for managment of these pests. thus, modern identification ...

the japanese threadfin bream, nemipterus japonicus, the most abundant and crucially economic nemipterus species is widespread throughout the indo-west pacific. the species has been studied widely for various aspects but genetic studies are scanty. this preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of n. japonicus...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

This paper presents a generic method for perceptual grouping, and an analysis of its expected grouping quality. The grouping method is fairly general: it may be used for the grouping of various types of data features, and to incorporate diierent grouping cues, operating over feature sets of diierent sizes. The proposed method is divided into two parts: Constructing a graph representation of the...

Abstract West Sumatra still stocks local chilies, which, based on information, have good resistance to viruses. This study aims characterize the morphology of several red chilies in due exploration. The characterization refers general guidelines for compiling descriptions vegetable (chili) varieties issued by Ministry Agriculture Republic Indonesia 2021. qualitative data from results were proce...

Behavioral studies suggest that perceptual grouping by proximity occurs earlier than grouping by similarity. This notion is supported by recent electrophysiological evidence that proximity grouping generates earlier occipital activation relative to grouping by shape similarity. The current work further investigated neural substrates that differentiate grouping by proximity and grouping by colou...
