We establish existence and non-existence results for entire solutions to the fractional Allen-Cahn equation in R, which vanish on helicoids and are invariant under screw-motion. In addition, we prove that helicoids are surfaces with vanishing nonlocal mean curvature.

We study the effect of a higher-order nonlinearity in the standard Kuramoto-Sivashinsky equation: partial differentialxG(Hx). We find that the stability of steady states depends on dv/dq , the derivative of the interface velocity on the wave vector q of the steady state. If the standard nonlinearity vanishes, coarsening is possible, in principle, only if G is an odd function of Hx. In this case...

In Nigeria, the threat posed by climate change is leading policymakers and media to frame as a security that warrants support for adaptive actions. We draw upon securitization theory examine how narratives affect adaptation. Using primary secondary data, we find although arguments are easily identified in policies action plans implications of adaptation policy practice harder discern. not urgen...

Most climate adaptation plans expect stakeholders to change their behavior as part of building resilience. Given its long-term and complex nature, monitoring evaluation is a key requisite for planning. So far, behavioral aspects have received only limited attention in the approaches This article proposes theory-based approach based on theory planned behavior, adaptation. A local programme water...

Abstract Climate mitigation and climate adaptation are crucial tasks for urban areas can involve synergies as well trade-offs. However, few studies have examined how efforts relate to each other in a large number of differently sized cities, therefore we know little about whether forerunners also leading or if cities tend focus on just one policy field. This article develops an internationally ...

The production task queue has a great significance for manufacturing resource allocation and scheduling decision. Man-made qualitative queue optimization method has a poor effect and makes the application difficult. A production task queue optimization method is proposed based on multi-attribute evaluation. According to the task attributes, the hierarchical multi-attribute model is established ...

background in addition to physical adaptation and psychosocial adjustment to chronic renal disease, hemodialysis (hd) patients must also adapt to dialysis therapy plan. objectives the aim of the present study was to examine the effect of roy’s adaptation model-based patient education on adaptation of hd patients. patients and methods this study is a semi-experimental research that was conducted...
