Effect of the Base-Pair Sequence on B-DNA Thermal Conductivity.

The thermal conductivity of double-stranded (ds) B-DNA was systematically investigated using classical molecular dynamics (MD) simulations. The effect of changing the base pair (bp) on the thermal conductivity of dsDNA needed investigation at a molecular level. Hence, four sequences, viz.

Thermal Conductivity of B-DNA.

The thermal conductivity of B-form double-stranded DNA (dsDNA) of the Drew-Dickerson sequence d(CGCGAATTCGCG) is computed using classical molecular dynamics (MD) simulations. In contrast to previous studies, which focus on a simplified 1D model or a coarse-grained model of DNA to reduce simulation times, full atomistic simulations are employed to understand the thermal conduction in B-DNA. Thermal conductivities at different temperatures from 100 to 400 K are investigated using the Einstein-Green-Kubo equilibrium and Müller-Plathe non-equilibrium formalisms.

Transient dynamic distributed strain sensing using photonic crystal waveguides.

This paper presents a new type of one-dimensional photonic crystal (PC) waveguide sensor and a technique for prediction of transient strain response accurately. The PC waveguide is integrated on a silicon substrate. We investigate the effect of non-uniform strain localization on the optical signal and use that information to capture the transient strain.
