hydrates are crystalline compounds similar to ice, with guest molecules like methane and ethane trapped inside cavities or cages formed by the hydrogen bounded framework of water molecules. these solid compounds give rise to problems in the natural gas oil industry because they can plug pipelines and process equipments. low dosage hydrate inhibitors are a recently developed hydrate control tech...

Konrad Menzel (NYU), "Strategic Network Formation with Many Agents" We consider a random utility model of strategic network formation, where we derive a tractable approximation to the distribution of network links using many-player asymptotics. Our framework assumes that agents have heterogeneous tastes over links, and allows for anonymous and non-anonymous interaction effects among links. The ...

We present an experimental and theoretical investigation of spontaneous pattern formation in the transverse section of a single retroreflected laser beam passing through a cloud of cold rubidium atoms. In contrast to previously investigated systems, the nonlinearity at work here is that of a two-level atom, which realizes the paradigmatic situation considered in many theoretical studies of opti...

We consider a random utility model of strategic network formation, where we derive a tractable approximation to the distribution of network links using many-player asymptotics. Our framework assumes that agents have heterogeneous tastes over links, and allows for anonymous and non-anonymous interaction effects among links. The observed network is assumed to be pairwise stable, and we impose no ...

background: scaling and corrosion are the two most important indexes in water quality evaluation. pollutants are released in water due to corrosion of pipelines. the aim of this study is to assess the scale formation and corrosion of drinking water supplies in ilam city (iran). methods: this research is a descriptive and cross-sectional study which is based on the 20 drinking water sources in i...
