The T-shaped double quantum dot system with single-walled metallic armchair carbon nanotube leads has been studied using Green functions obtained by the equation of motion method. The effect of relative spacing between the energy levels of the dots, interdot tunneling matrix-element, interdot Coulomb interaction, and van-Hove singularities in density of states characteristics of quasi-one-dimensional carbon nanotube leads on the conductance of the double quantum dot system has been studied. The conductance and dot occupancies are calculated at finite temperatures. The density of states of the carbon nanotube leads is observed to play a significant role in determining the conductance profile. In particular, whenever the chemical potential of the isolated double quantum dot system is aligned with the position of a van-Hove singularity in the density of states of armchair carbon nanotube leads, the height of the corresponding conductance peak falls considerably. It is further observed that the suppression in the heights of the alternate peaks depends on the relative positions of the energy levels of the dots and their magnitude of separation.

Aging and longevity is a dynamic, chronological process assumed to originate from several hallmarks causing archetypal and beguiling cycles with incredible natural diversity. This phenomenon is widely observed in different animals, and the estimated age of Drosophila melanogaster, Caenorhabditis elegans, Daphnia longispina are a few days to weeks. Reproductive termites live for 30 years, although the root cause of longevity in termite castes is still debated for molecular and cellular changes. Insulin and insulin signaling pathway-related (IIS) genes are important metabolic factors (glucose) highly conserved in lower to higher organisms. Therefore, in this study, we pooled Reticulitermes chinensis castes as primary king (PK), primary queen (PQ), ergatoid king “SWRK” and queen “SWRQ”,male (WM), and female (WF) workers. We determined transcriptome sequencing of R. chinensis castes as a model organism for longevity to investigate the insulin signaling pathway and longevity genes. Through RNA-sequencing, we identified 35 IIS- pathway-related genes out of 343 to the KEGG pathway in ergatoid king and queen, PK, PQ, WM, and WF. Among these genes, Ts c 2 , akt2-a, mTOR, EIF4E, Pdk1,and RPS expressed highly in ergatoid king and queen, PK, and PQ. However, a significant cornerstone tradeoff between reproductive and non-reproductive efforts for early life is essential for evolutionary longevity. The present study concludes that a highly conserved IIS-pathway is evidence for the prolonged termite reproductive life span. We recommended devoting insulin signaling pathway genes to their biological function for termite survival and new insights into the maintenance and relationships between biomolecular homeostasis and remarkable longevity.
Impact of urbanization on land use/ land cover of Dudhganga watershed of Kashmir Valley, India
Haroon Sajjad,Mohd Iqbal 서울시립대학교 도시과학연구원 2012 도시과학국제저널 Vol.16 No.3
The rapid rate of urban expansion due to a rise in population and economic growth is causing land use/land cover changes in fringe areas of Srinagar city especially in the Dudhganga watershed. This paper analyzes land use/land cover changes that occurred due to urban expansion and points out the major impact of urbanization on landscape through multi-temporal Landsat satellite data (1991and 2010) of the Dudhganga watershed. In order to assess the pattern of urbanization, land consumption ratio (LCR) and land absorption coefficient (LAC) have been estimated. The results revealed that throughout the period of 1991–2010, the amount of built up area has increased dramatically whereas the area under agriculture has decreased drastically. The built-up area has experienced an increase of 5056 hectares while the area under agriculture has witnessed a decrease of 3241 hectares. The values of land consumption ratio and land absorption coefficient reveal remarkable changes at both spatial and temporal scales. The lower reaches of the watershed are becoming urbanized due to the outer growth of Srinagar city at the cost of prime agricultural land. Serious environmental problems have cropped up as a result of rapid urban development. If the present trend continues it will lead to severe degradation of natural resources of the watershed, hence it calls for a proper land use policy.
DEGENERATE BERNOULLI NUMBERS AND POLYNOMIALS ASSOCIATED WITH DEGENERATE HERMITE POLYNOMIALS
Haroon, Hiba,Khan, Waseem Ahmad Korean Mathematical Society 2018 대한수학회논문집 Vol.33 No.2
The article is themed to classify new (fully) degenerate Hermite-Bernoulli polynomials with formulation in terms of p-adic fermionic integrals on $\mathbb{Z}_p$. The entire paper is designed to illustrate new properties in association with Daehee polynomials in a consolidated and generalized form.

Hypoderma spp. larvae cause subcutaneous myiasis in several animal species. The objective of the present investigation was to identify and characterize morphologically and molecularly the larvae of Hypoderma spp. collected from cattle (Bos taurus taurus) and red deer (Cervus elaphus) in the district of Castelo Branco, Portugal. For this purpose, a total of 8 larvae were collected from cattle (n=2) and red deer (n=6). After morphological identification of Hypoderma spp. larvae, molecular characterization was based on PCR-RFLP and mitochondrial CO1 gene sequence analysis. All larvae were morphologically characterized as the third instar larvae (L3) of H. actaeon. Two restriction enzymes were used for molecular identification of the larvae. TaqI restriction enzyme was not able to cut H. actaeon. However, MboII restriction enzyme differentiated Hypoderma species showing 210 and 450 bp bands in H. actaeon. Furthermore, according to the alignment of the mt-CO1 gene sequences of Hypoderma species and to PCR-RFLP findings, all the identified Hypoderma larvae were confirmed as H. actaeon. This is the first report of identification of Hypoderma spp. (Diptera; Oestridae) from cattle and red deer in Portugal, based on morphological and molecular analyses.
