Survival data collected from a prevalent cohort are subject to left truncation and the analysis is challenging. Conditional approaches for left-truncated data could be inefficient as they ignore the information in the marginal likelihood of the truncation times. Length-biased sampling methods may improve the estimation efficiency but only when the underlying truncation time is uniform; otherwis...

We present seismic zoning maps of the National Capital Region (NCR) India in terms uniform hazard spectrum (UHS) amplitudes using three different attenuation equations to model contributions local earthquakes around region and distant northwestern Himalaya (NWH) Hindu Kush Subduction (HKS) sources. Our results show that shape design spectra must depend on nature contributing earthquake sources,...

The city of Kolkata, the State Capital of West Bengal is jolted by earthquakes time and again from the tectonic regimes of the Central Himalaya, highly seismogenic Northeast India and the active tectonics of Bengal Basin which is a pericratonic tertiary basin on which the City is located. Earthquake disaster mitigation and management necessitates seismic hazard assessment for the generation of ...

Abstract In this work, we construct different classes of coherent states related to a quantum system, recently studied in [1], an electron moving plane uniform external magnetic and electric fields which possesses both discrete continuous spectra. The eigenfunctions are realized as orthonormal basis suitable Hilbert space appropriate for building the states. These latter achieved context where ...

Obtaining unambiguous resonance assignments remains a major bottleneck in solid-state NMR studies of protein structure and dynamics. Particularly for supramolecular assemblies with large subunits (>150 residues), the analysis of crowded spectral data presents a challenge, even if three-dimensional (3D) spectra are used. Here, we present a proton-detected 4D solid-state NMR assignment procedure ...

We develop a tight-binding model description of semi-Dirac electronic spectra, with highly anisotropic dispersion around point Fermi surfaces, recently discovered in electronic structure calculations of VO2-TiO2 nanoheterostructures. We contrast their spectral properties with the well-known Dirac points on the honeycomb lattice relevant to graphene layers and the spectra of bands touching each ...
