Nonequilibrium Fluctuations In Sedimenting And Self-Propelled Systems
(2013-06-10)Equilibrium statistical mechanics has a remarkable property: the steady state probability distribution can be calculated by a procedure independent of the detailed dynamics of the system under consideration. The partition ... -
Nonlinear analysis of lower hybrid by many-body techniques
In some recent experiments, intense ion heating has been observed. This heating has been attributed to the excitation of the lower hybrid in the inhomogeneous magnetoactive plasma. The level of turbulence is observed to ... -
Nonlinear Charge Transport and Photo-Physical Studies in Conjugated Polymers (P3meT, P3HT) and their Hybrid Composites with Silver Sulfide Quantum Dots
Organic semiconductors have been investigated as an emerging class of materials for their viable applications in electronics. Despite considerable improvement in device properties, a better understanding of the nature of ... -
Nonlinear propagation of intense electromagnetic waves in quasar and pulsar plasmas
his thesis presents the results of analytical as well as numerical investigations of radiation–plasma interaction instabilities in astrophysical plasmas. It consists of two introductory chapters, four main chapters, and ... -
Nonreciprocity, condensation and chirality in active granular systems
We present a journey into the rich non-equilibrium phenomena of active granular systems, a versatile model for studying “living” materials. Our exploration begins with the discovery of non-reciprocal, medium-mediated ... -
Novel Spectral Processing Methods in NMR – Wavelet Transform and Pattern Based Analysis
NMR spectroscopy provides a variety of information leading to an understanding of the properties of different materials. To extract this information from the experiments, one needs to have noise and artifacts free spectra ... -
Novel spin, charge, and lattice dynamics in pyrochlore iridates : Raman and X-ray diffraction studies at low temperatures and high pressure
This thesis investigates phonon dynamics, electronic, and spin excitations along with structural instabilities and phase transitions in rare earth pyrochlore iridates, A2Ir2O7 (A = Pr, Gd, Dy, and Er) and Bi-doped Sm2Ir2O7 ... -
De Novo Design Of Protein Secondary And Super Secondary Structural Elements: Investigation Of Interaction Patterns From The Crystal Structure Analysis Of Oligopeptides Containing α,β-Dehydrophenylalanine Crystal Structure Analysis Of Double Mutant M37L, P40S Thioredoxin From E.Coli
(2007-12-06)ΔPhe an analogue of a coded amino acid phenylalanine (Phe) residue but with double bond between Cα and Cβ atoms, is one of the well studied residue among all the dehydro amino acids, as a conformation constraining amino ... -
Nuclear magnetic resonance inestigations at high....pressure
In this review it has been attempted to give a summary of the MR experiments which have been used to investigate high pressure effects on the molecular motion, diffusion and phase transitions in solids. These experiments ... -
Nuclear magnetic resonance investigations of certain protonic conductors.
Ionic motion in the hydrate of ammonium ferrocyanide has been investigated by high?pressure wide?line NMR, high?resolution NMR and conductivity techniques. In the high?pressure NMR study, the room?temperature proton NMR ... -
Nuclear quadrupole resonance and relaxation - instrumentation and investigations in group V Trihalides
In the present investigation, we have used nuclear quadrupole resonance (NQR) as a local probe to study the structural and dynamical aspects of Group V trihalides. For this purpose, we have set up a pulsed NQR spectrometer ... -
Numerical Studies of Problems in Turbulence : 1) Fluid Films with Polymer Additives; 2) Fluid Films with Inertial and Elliptical Particles; 3) Scaled Vorticity Moments in Three- and Two-dimensional Turbulence
(2017-11-30)In this thesis we study a variety of problems in fluid turbulence, principally in two dimensions. A summary of the main results of our studies is given below; we indicate the Chapters in which we present these. In Chapter ... -
Numerical Studies Of Slow Dynamics And Glass Transition In Model Liquids
(2009-12-16)An increase in the co-operativity in the motion of particles and a growth of a suitably defined dynamical correlation length seem to be generic features exhibited by all liquids upon supercooling. These features have been ... -
Numerical Studies of Spiral- and Scroll-wave Dynamics in Cardiac Tissue: (1) Spiral- and Scroll-Wave Turbulence; (2) Spiral- and Scroll-Wave dynamics in Anatomically and Physiologically realistic Mathematical Models for Canine and Human Ventricular Tissue
A summary of the main results of our studies is given below. In most of our work, we use three mathematical models for cardiac myocytes, namely, the Panfilov model, the Aliev-Panfilov model, and the Hund-Rudy-Dynamic ...
