Introduction: Alzheimer’s disease (AD) is one of the most common neurodegenerative disorders. It is characterized by memory loss and cognitive decline. Extracellular amyloid beta (Aβ) plaques and intracellular neurofibrillary tangles of tau have been ascribed for the pathogenesis of AD. Aβ40/42 polypeptides, a product of abnormal cleavage of amyloid precursor protein by β-secretases (BACE1) and γ-secretases, is known to follow nucleus-dependent aggregation kinetics, which leads to the format...
The alarming rise in temperatures in recent years has increased the energy required to maintain the thermal comfort of building occupants. Phase change materials (PCMs) can store thermal energy and reduce this energy consumption. This paper summarizes the current developments in using PCMs in building construction. We discuss the working principle, the classification of PCMs, technologies to use PCMs at a material level in construction, the current problems involving PCM usage and their possi...
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...
