Systematics of intermediate-energy single-nucleon removal cross sections
There is now a large and increasing body of experimental data and theoretical
analyses for reactions that remove a single nucleon from an intermediate-energy
beam of neutron- or proton-rich nuclei. In each such measurement, one obtains
the inclusive cross section for the population of all bound final states of the
mass A-1 reaction residue. These data, from different regions of the nuclear
chart, and that involve weakly- and strongly-bound nucleons, are compared with
theoretical expectations. These calculations include an approximate treatment
of the reaction dynamics and shell-model descriptions of the projectile initial
state, the bound final states of the residues, and the single-particle
strengths computed from their overlap functions. The results are discussed in
the light of recent data, more exclusive tests of the eikonal dynamical
description, and calculations that take input from more microscopic nuclear
structure models.Comment: 4 pages, 1 figure, with reference correcte
Internet of Things (Iot) for Smart Cities- The Future Technology Revolution
Today the world is becoming connected. The number of devices that are connected are increasing day by day. Many studies reveal that about 50 billion devices would be connected by 2020 indicating that Internet of things have a very big role to play in the future to come. The applications of IoT are immense which include Energy, Healthcare, and Agriculture to name a few. IoT is an emerging technology that works with the integration of many other present day technologies. There are many threats to the environment today among them urbanization is one. The growing needs of the uraban population across the world are posing a serious threat to the environment. We need to act fast and meet these needs by developing technologies that cater the world problems. One such solution is to develop a smart world. The most important application of IoT is smart cities. Smart city represents one of the most promising, important and difficult Internet of Things (IoT) applications. In the last few years, the smart city concept has played an important role in both scholastic and industry fields, with the advancement and operation of various middleware platforms and IoT-based infrastructures. This paper talks about the role of IoT in developing smart cities for a smarter world

Pattern Formation on Trees
Networks having the geometry and the connectivity of trees are considered as
the spatial support of spatiotemporal dynamical processes. A tree is
characterized by two parameters: its ramification and its depth. The local
dynamics at the nodes of a tree is described by a nonlinear map, given rise to
a coupled map lattice system. The coupling is expressed by a matrix whose
eigenvectors constitute a basis on which spatial patterns on trees can be
expressed by linear combination. The spectrum of eigenvalues of the coupling
matrix exhibit a nonuniform distribution which manifest itself in the
bifurcation structure of the spatially synchronized modes. These models may
describe reaction-diffusion processes and several other phenomena occurring on
heterogeneous media with hierarchical structure.Comment: Submitted to Phys. Rev. E, 15 pages, 9 fig
Spectral Properties and Synchronization in Coupled Map Lattices
Spectral properties of Coupled Map Lattices are described. Conditions for the
stability of spatially homogeneous chaotic solutions are derived using linear
stability analysis. Global stability analysis results are also presented. The
analytical results are supplemented with numerical examples. The quadratic map
is used for the site dynamics with different coupling schemes such as global
coupling, nearest neighbor coupling, intermediate range coupling, random
coupling, small world coupling and scale free coupling.Comment: 10 pages with 15 figures (Postscript), REVTEX format. To appear in

A water-soluble tetraazaperopyrene dye as strong G-quadruplex DNA binder
The interactions of the water-soluble tetraazaperopyrene dye 1 with ct-DNA, duplex-[(dAdT)12⋅(dAdT)12], duplex-[(dGdC)12⋅(dGdC)12] as well as with two G-quadruplex-forming sequences, namely the human telomeric 22AG and the promotor sequence c-myc, were investigated by means of UV/visible and fluorescence spectroscopy, isothermal titration calorimetry (ITC) and molecular docking studies. Dye 1 exhibits a high affinity for G-quadruplex structures over duplex DNA structures. Furthermore, the ligand shows promising G-quadruplex discrimination, with an affinity towards c-myc of 2×107 m−1 (i.e., Kd=50 nm), which is higher than for 22AG (4×106 m−1). The ITC data reveal that compound 1 interacts with c-myc in a stoichiometric ratio of 1:1 but also indicate the presence of two identical lower affinity secondary binding sites per quadruplex. In 22AG, there are two high affinity binding sites per quadruplex, that is, one on each side, with a further four weaker binding sites. For both quadruplex structures, the high affinity interactions between compound 1 and the quadruplex-forming nucleic acid structures are weakly endothermic. Molecular docking studies suggest an end-stacking binding mode for compound 1 interacting with quadruplex structures, and a higher affinity for the parallel conformation of c-myc than for the mixed-hybrid conformation of 22AG. In addition, docking studies also suggest that the reduced affinity for duplex DNA structures is due to the non-viability of an intercalative binding mode
