Deterministic Two Stage Clonal Expansion Model of Breast Cancer Epidemiology and its Utility for Optimal Screening Policies in India
Breast cancer (BC) has emerged as public health issue in India in last two decades sur-passing cervix cancer. Mortality from breast cancer is 30-40% higher than maternal causes. Breast cancer 5 year survival rates are ...
Magnetic and Dielectric Properties of Half Doped RMnO3 (R = Y, Tb)
For the last few decades, the physics of doped perovskite manganite’s (RMnO3) has been an area of intense research due to their interesting physical and electronic properties. Various exciting phenomena such as, colossal ...
Studies of X-Ray Transients and a Future X-Ray Sky Monitor
For this thesis we studied X-ray transients. In addition we also studied some methods to study these transients, both observationally and in terms of the instrument used.
The first transient studied is a black hole binary ...
1H-NMR Study of Proton Glasses - Nuclear Spin Lattice Relaxation in BPxBPI(1-x) and BPxGPI(1-x) - Effects of Disorder on the Proton Group Dynamics
Mixed systems made from a combination of ferroelectric (FE) and antiferroelectric (AFE) compounds, exhibit various effects of disorder in different temperature regions. The kind of effects observed, depend on the technique ...
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ...
Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rare-earth manganites with the general formula T1xDxMnO3 where `T' is a trivalent
rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion,
e.g Ca2+; Sr2+;Ba2+ etc. display various ...
Particles and Fields in Partial-differential-equation Models for fluid and Superfluid Turbulence
We have shown that uniformly rotating vortex-containing gravitationally-bound
solutions of the GPPE can be generated by starting the evolution from initial data
obtained by integrating to convergence the (imaginary-time) ...
Tuning the electrical and thermoelectric properties of bilayer graphene by band engineering
Graphene and its two dimensional (2D) analogues have sustained the interests of the
researchers for quite some time because of the rich physics they offer including many
quantum phenomena and non-trivial topological ...
Tuning of Spin Reorientation and Compensation Transitions in Ferrites
Ferrites have attracted the attention of scientists and engineers in the last few years because of a combination of ferrimagnetic and insulating character. This makes them suitable for high frequency devices in telecommunication ...
Studies of Diamagnetism and Thermoelectric Transport in High Temperature Superconductors and Graphene
Using a recently proposed Ginzburg-Landau-like free energy functional due to Banerjee et al. Phys. Rev. B 83, 024510 (2011) we calculate the fluctuation diamagnetism of high-T c superconductors as a function of doping, ...
