The cold dark matter (CDM) model of structure formation, normalized on large scales, leads to excessive pairwise velocity dispersions on small scales. In an attempt to circumvent this problem, we study three scenarios (all with Ω = 1) which have more large-scale power and less small-scale power than the CDM model: 1) an admixture of cold and hot dark matter; 2) cold dark matter with a non-scale...

Discrepancies have emerged between the predictions of standard cold dark matter (CDM) theory and observations of clustering on sub-galactic scales. Warm dark matter (WDM) is a simple modification of CDM in which the dark matter particles have initial velocities due either to their having decoupled as thermal relics, or having been formed via non-equilibrium decay. We investigate the nonlinear g...

Recently, user who uses a multimedia files demands a high capacity file via internet. However, it is difficult to guarantee QoS about providing high capacity files by internet because that has an inconstant bandwidth. For guaranteeing the QoS, CDN (Content Delivery Network) is generally used as a method of contents delivery service. Based on CDN, we propose Content Distribution and Management u...

Replenishing nutrients through organic sources is essential to maintain the soil health and sustainability in Eastern Himalayan Region, India which is organic by default. Keeping this in mind an experiment was laid out on randomized block design with six treatments viz., T1: Vermicompost (VC; 2.5 Mg ha-1), T2: Poultry manure (PM; 1.25 Mg ha-1), T3: Swine manure (SM; 3.0 Mg ha-1), T4: Cow du...

Hierarchical clustering models of cold dark matter (CDM) predict that about 5% 10% of a galaxy-sized halo with mass ∼ 10 solar masses (M⊙) resides in substructures (CDM subhalos) with masses ∼ < 108M⊙. To directly identify such substructures, we propose to observe radio continuum emission from multiply imaged QSOs using VSOP-2 with a high angular resolution.

A recent observation of Steidel et al. indicates that a substantial fraction of giant galaxies were formed at an epoch as early as redshift z > 3− 3.5. We show that this early formation of giant galaxies gives strong constraints on models of cosmic structure formation. Adopting the COBE normalization for the density perturbation spectrum, we argue that the following models do not have large eno...

Be it snow, volcanic ash or strikes, crisis events impose high costs on the air transport system and society. Airlines have progressively learned to mitigate the irregular operations arising from such events through procedures such as Collaborative Decision Making (CDM) for tra c ow and airport departure management; however the passenger's door-to-door journey during di cult times often remains...

We report on a culture method for the rapid production of a strong and thick natural matrix by human cells for tissue engineering applications. Dermal fibroblasts were cultured for three weeks at high density on porous substrates in serum-containing or chemically defined media. The mechanical and biochemical properties of the resulting cell-derived matrix (CDM) were compared to those of standar...

The gravitational lensing properties of cosmological halos depend upon the mass distribution within each halo. The description of halos as nonsingular, truncated isothermal spheres, a particular solution of the isothermal Lane-Emden equation (suitably modified for Λ 6= 0), has proved to be a useful approximation for the halos which form from realistic initial conditions in a CDM universe. The n...
