The daily traffic on bridges, the moisture of the atmosphere and the tiredness of materials, cause damages even the collapse of these works, if there is not a policy of maintenance and maintenance allowing the detection of possible defects in these structures and the intervention in the convenient period. These degradations can be cracks types (longitudinal or transverse), vacuums, corrosion or...

Various TeVeS-like and f(R)-like theories of gravity have added an interesting twist to the search for dark matter and vacuum energy, modifying the landscape of astrophysics day by day. A common thread of various theories is a non-uniform vector field fluid in the vacuum (see an up-to-date summary of relations between various theories by Halle, Zhao & Li, arXiv0711.0958 1). These ”alternative” ...

Soft lithography molding is a promising technique for patterning polymer integrated optical devices, however the presence of a background residue has the potential to limit the usefulness of this technique. We present the soft lithography technique for fabricating polymer waveguides. Several effects of the background residue are investigated numerically, including the modal properties of an ind...

Nanotechnologies have attracted wide interests and evolved rapidly in the past two decades. They are expected to have transformative impacts on the health, environment, energy, and many other aspects of our society. However, their applications so far are severely hindered by the lack of matured and affordable manufacturing technologies to realize systems in large scales where millions of nanosc...

The problem of water wave scattering by a semi-infin ite floating dock on the free surface of an ocean with variable bottom topography is considered using linear theory. By employing a perturbation analysis and using Green's integral theorem, the analytical expression for the first order reflection coefficient is obtained in terms of a computable integral involving the bottom shape function. Al...

Since the low mass of $D^*_{s0}(2317)$ has still been a problem to conventional quark model, one can consider other options regarding as multi-quark system. Therefore we investigate scalar open-charm state by Thermal QCD Sum Rules (TQCDSR) method using two-point correlation function together with contributions non-perturbative condensates up dimension six. Deriving and numerically analyzing the...
