Journal ArticleDOI
Non-adiabatic Modal Dynamics around Exceptional Points in an All-Lossy Dual-Mode Optical Waveguide: Towards Chirality Driven Asymmetric Mode-Conversion
TL;DR: In this paper, a 1D planar optical waveguide with transverse distribution of inhomogeneous loss profile, which exhibits an exceptional point (EP), is presented, where the interaction between them in the vicinity of the EP is controlled by proper adjustment of the inhomogeneity in attenuation profile only.
Journal ArticleDOI
Novel 1,4-dihydropyridine induces apoptosis in human cancer cells through overexpression of Sirtuin1.
TL;DR: It is suggested that the apoptotic effect of DHP-8 in A375 and HepG2 cells was mediated by AKT and survivin pathways through SIRT1 activation, and the possible potential and therapeutic role of D HP-8 is emphasized in skin and liver cancer.
Journal ArticleDOI
Electric field enhanced spreading of partially wetting thin liquid films.
TL;DR: Equilibrium and dynamic electrowetting behavior of ultrathin liquid films of surfactant (SDS) laden water over silicon substrate (with native oxide) is investigated and contact line instability resulting in emission of droplets from the curved meniscus has been observed.
Journal ArticleDOI
Phase evolution and photoluminescence in as-deposited amorphous silicon nitride films
Sarab Preet Singh,P. C. Srivastava,Somnath Ghosh,Shahbaz Khan,Claudio J. Oton,G. Vijaya Prakash +5 more
TL;DR: In this paper, a systematic study of hydrogenated amorphous silicon nitride films deposited by varying gas flow rate ratio (R ǫ = SiH 4 /NH 3 ) using Photo-Chemical Vapour Deposition (PCVD) was conducted.
Journal ArticleDOI
Higher-order topological degeneracies and progress towards unique successive state switching in a four-level open system
TL;DR: In this paper, a four-level parameter-dependent perturbed non-Hermitian Hamiltonian was proposed to explore the physical aspects of an EP4 analytically as well as numerically.
