A stiff thin film on a heated compliant substrate may buckle when the system is cooled due to the thermal expansion mismatch between the film and substrate. Highly ordered and disordered herringbone patterns wavy structures then emerge as the system continues to cool. We have established an analytic approach to study one-dimensional, checkerboard, and ordered herringbone buckling patterns. The ...

A new Galerkin-type procedure is established which, unlike the classical approach, does not rely on the nal shape being composed of linearly independent modes. The procedure is applied to the evolution of a localized buckle of a thin elastic strip within a visco-elastic medium. Unlike the related elastic problem, no clear-cut linear eigenvalues exist to model wavelength and exponential growth/d...

Breaststroke, butterfly, front crawl and back crawl: many of us learnt these swimming styles as kids while splashing around in our local pool. These strokes all involve the swimmer lying on their back or front, much like the way most fish swim. Of course, some people prefer to swim tilted to one side rather than face down even though the side-stroke evokes images of elderly swimmers in bathing ...

Iraq has used chemical warfare agents in recent Iran-Iraq conflict ( 1980-88) . There are few studies regarding late complications of chemical warfare and there is no report concerning late cutaneous complications. The present study is concerned with the late clinical manifestation of cutaneous complications in chemical warfare casualties in comparison to non – chemical injured soldiers. Upon t...

The buckle before the lens coating is still typically disassembled manually. difference between and background small, while that buckles large. This mechanical disassembly can also damage lens. Therefore, it important to estimate pose with high accuracy. paper proposes a estimation method based on generative adversarial network. An edge extraction model designed segmentation network as generato...

A complete set of harmonic force constants describing the DNA deformation energetics at the base pair level was obtained using unrestrained atomic-resolution molecular dynamics simulations of selected duplex oligonucleotides and subsequent analysis of structural fluctuations from the simulated trajectories. The deformation was described by the six base pair conformational parameters (buckle, pr...
