The design of highly wavelength tunable semiconductor laser structures is presented. The system is based on a one dimensional photonic crystal cavity consisting of two patterned, doubly-clamped nanobeams, otherwise known as a "zipper" cavity. Zipper cavities are highly dispersive with respect to the gap between nanobeams in which extremely strong radiation pressure forces exist. Schemes for con...

DNA origami structures represent an exciting class of materials for use in a wide range biotechnological applications. This study reports the design, production, and characterization “zipper” structure, which contains nine pH-responsive locks. Each lock consists two parts that are attached to zipper’s opposite arms: hairpin single-stranded able form triplex through Hoogsteen base pairing. The s...

Recent studies have indicated the need of considering aftershocks in seismic design/assessment structures. This article investigates effect sequential mainshock and aftershock earthquakes on eccentrically braced steel frames with vertical energy-absorbing links. To achieve this, 4, 8 12-storey frame buildings are modelled Perform3D® software non-linear behaviour materials components. The subjec...

Multinucleated osteoclasts are responsible for bone resorption. Hypermultinucleated osteoclasts are often observed in some bone-related diseases such as Paget's disease and cherubism. The cellular mechanics controlling the size of osteoclasts is poorly understood. We introduced EGFP-actin into RAW 264.7 cells to monitor actin dynamics during osteoclast differentiation. Before their terminal dif...

In the last decades, high priority has been given by research community to development of low-damage structures, and reparability become fundamental for minimizing environmental economic impact reconstruction. this context, European Research Fund Coal Steel (RFCS) project DISSIPABLE was carried out, with aim test large-scale structures where dissipation is concentrated on replaceable components...

In recent years, the devastating earthquakes that occurred in many parts of world have made it even more important design earthquake-resistant structures and earthquake performance assessment existing structures. When innovative systems are examined building design, is seen depending on developments performance-based designs come to fore addition force-based design. This paper provides a new me...

Existing literature suggests that substituting mineral aggregates with tire-derived aggregate (TDA) in concrete increases the ductility and toughness of at cost lowering its strength stiffness. Hence, TDA has applications dynamic systems, such as lateral resisting frames sustaining seismic loads. This study investigated application buckling-restrained braced (BRBFs). Buckling-restrained brace (...
