Paying off the mortgage, once a widespread rite of passage for homeowners approaching retirement, has become less common in recent years. Concerns are mounting that the increased prevalence of housing debt among older homeowners could compromise financial security in retirement by expanding housing affordability problems, crimping essential nonhousing spending, increasing vulnerability to home ...

generally an important part of changes in architectural constructions are represented by convertible structures. these kinds of structures are composed typically of hard or soft materials or combination of both, which avoid independent structural deformations and need additional elements such as hinges, rollers or other similar components. development of new construction materials like fiber-re...

In soft robotics, the ability to generate advanced kinematics is a necessary step toward any more sophisticated tasks such as microobject manipulation, locomotion, or configuration changes. To this end, herein, modular voxel-based methodology adaptable scale and with transducer presented. The implemented at micrometer one-step fabrication process. An innovative gray-tone lithography method usin...

We apply the dressing method to a string solution given by a static string wrapped around the equator of a three-sphere and find that the result is the single spike solution recently discussed in the literature. Further application of the method allows the construction of solutions with multiple spikes. In particular we construct the solution describing the scattering of two single spikes and c...

Dissociative recombination of N$_2$H$^+$ is explored in a two-step theoretical study. In first step, diatomic (1D) rough model with frozen NN bond and angles adopted, the framework multichannel quantum defect theory (MQDT). The importance indirect mechanism bending mode revealed, spite disagreement between our cross section experimental one. second we use recently elaborated 3D approach based o...
