Quantum state transfer plays an important role in quantum information processing. A quantum network can be modeled by a graph G where the vertices correspond to the qubits and the edges represent the interactions between them. In a quantum network, we find the dynamics of some pair states with Heisenberg XY Hamiltonian remains unaffected with the change of the total structure. Graphs with perfect state transfer can be taken as analogous components of graph associated to a broad quantum networ...

Biomolecular condensate formation within the cell is regulated via weak multivalent interactions between intrinsically disordered proteins (IDPs). Recent evidences suggest the formation of such condensates prior to pathogenic aggregates. The aggregated states of the presynaptic intrinsically disordered protein, α-Synuclein have long been associated with Parkinson’s disease. Although α-Synuclein aggregation is majorly driven by the non-amyloid β- component (NAC) domain, a 7-residue sequence kn...
Comprehending the fracture behaviour of concrete is a difficult task due to its multiscale heterogeneous structure at different length scales, extending from nanoscale to macroscale. The Calcium Silicate Hydrate (CSH) gel is the major binding phase in concrete structures, responsible for the overall mechanical and fractural strength. At atomic scale, interaction of CSH gel under different loading conditions can provide insights into the fracture process of concrete. To study load resistance c...

The development of next-generation sequencing technologies has resulted in exponential growth in sequence data. Global or local, pairwise or multiple sequence alignment was the foundation of early methods for sequence analysis, which was computationally intensive and time-consuming. In addition, gaps, mismatches, and insertions/deletions might provide unsatisfactory results during the alignment process, particularly for highly divergent sequences. We have used alignment-free sequence analysis...
In this work, we explore an ambient backscatter system (AmBS) comprising an ambient source, multiple tags, and a reader. Herein, an ambient source communicates with its legacy user. The radio frequency (RF) signal transmitted by the ambient source is overheard by a selected tag that reflects the received signal after modulating by its own message. Further, we assume that ambient source and reader node of considered AmBS are corrupted by RF hardware impairments (RFHI). RFHI is caused by cheap ...
