TL;DR: In this paper, multiple etalon systems are discussed that meet the science requirements for a narrow-passband imaging system for the 4-meter National Solar Observatory (NSO)/Advance Technology Solar Telescope (ATST).

TL;DR: In this article, a new automated algorithm is presented to identify, track, and characterize small-scale brightening associated with solar eruptive phenomena observed in Hα, which can be separated into two categories: flare ribbons and sequential chromospheric brightening (SCBs) within each category of brightening, the smallest resolvable locus of pixels, a kernel and track the temporal evolution of the position and intensity of each kernel.

TL;DR: In this paper, two oppositely charged polymers polystyrene sulfonate sodium salt (PSS) and poly-diallyl-dimethyl-ammonium chloride (PDDA) are used separately to functionalize the multiwalled carbon nanotubes (CNTs) and it dispersed in poly (vinylidene difluoride) (PVDF) polymer matrix to get flexible nanocomposite strain sensor to investigate both electrical conductivity and the gauge factor.

TL;DR: In this article, the authors measured oscillation properties in flares and filaments from H-alpha chromospheric data using a new method that provides important spatial and frequency content of the dynamics.

TL;DR: In this paper, the authors developed a technique for estimating an aluminium/epoxy/aluminium lap shear joint stiffness using periodic permanent magnet electromagnetic acoustic transducers (PPM EMATs).
