Probing the inflationary universe and reheating with primordial black holes and induced gravitational wave background
The direct observational test for the earliest phase of our universe comes from cosmic microwave background (CMB) radiation, which can only probe up to the recombination era. The only definitive event during the pre-recombination ... -
Probing the Nature of Dark Matter in the Universe
The dark matter is the most dominating matter candidate and a key driving force for the structure formation in the universe. Despite decade-long searches, the precise nature and particle properties of dark matter are ... -
Probing The Origin Of Second Harmonic Generation From Copper Nanoparticles In Solution By Hyper-Rayleigh Scattering
(2010-08-09)In recent years, coinage metal nanoparticles have emerged as materials with largest quadratic optical nonlinearity. Their first hyperpolarizabilities (β) are very high (105-106 x 10-30 esu) but such large values were quite ... -
Probing the Role of Highly Conserved Residues in Triosephosphate Isomerase : Biochemical & Structural Investigations
(2018-05-23)Conserved residues in protein are crucial for maintaining structure and function, either by direct involvement in chemistry or indirectly, by being essential for folding, stability and oligomerisation and are mostly clustered ... -
Probing the Splicing and Enzymatic Function of Fission Yeast Prp16 – A DEAD Box RNA Helicase
Nuclear pre-mRNA splicing occurs at precisely conserved sequence elements at and around the splice sites which result in ligation of exons and release of intron as lariat. The Schizosaccharomyces pombe genome is an apt ... -
Problems on bend-number, circular separation dimension and maximum edge 2-colouring
Representation of graphs as the intersection graphs of geometric objects has a long history. The objective is to a nd a collection of \simple" sets S such that a given graph G is its intersection graph. We are interested ... -
Process Variability-Aware Performance Modeling In 65 nm CMOS
(2011-02-25)With the continued and successful scaling of CMOS, process, voltage, and temperature (PVT), variations are increasing with each technology generation. The process variability impacts all design goals like performance, ... -
Processing And Characterisation Of Bulk Al2 O3 p /AIN-Al Composites By Pressureless Infiltration
(Indian Institute of Science, 2005-12-22)Al-Mg alloys were infiltrated into porous alumina preforms at temperatures greater than 950°C where significant amount of nitride forms in the matrix. The present work aims to obtain a process window for growing A1N rich ... -
