Dictionary Based Channel Estimation and Precoding Techniques for Massive MIMO Wireless Communication Systems
Massive multiple-input multiple-output (MIMO) systems constitute a promising enabling technique for 5G/6G cellular networks as a benefit of their substantial spatial multiplexing gain in both time division duplex (TDD) and ... -
Signatures of Co-existing Dual Topological Surface States in Topological Insulators using Scanning Tunneling Spectroscopy and Electrical Transport
Topological insulators host exotic metallic states on their surfaces even when the bulk is insulating. The distinctive conducting surfaces of topological insulators present a novel domain for investigating the physics of ... -
A Geochemical, Sr isotopic, and numerical study of river water, groundwater, and sea water interaction in the tidally dominated Hooghly (Ganga) estuary
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with saline water from the ocean. It is a dynamic system that is characterized by large changes in water chemistry (e.g., ... -
Itaconate Based Dual-reactive Polymeric Coatings and Photo-cross-stitching Studies of Periodically Grafted Amphiphilic Systems
Dual-reactive coatings are those that covalently anchor to the substrate while at the same time permit installation of desired segments in a post-coating step; several approaches have been developed to design such polymers ... -
Proximity-induced superconductivity in a dual topological insulator and crossover from gapped-to-gapless Dirac surface states in a magnetic topological insulator
The combination of non-trivial topology and superconductivity is predicted to give rise to exotic Majorana fermions at the vortex core, forming a topological superconductor (TSC). TSCs, crucial for fault-tolerant quantum ... -
