the p53 protein function is essential for the maintenance of the nontumorigenic cell phenotype. pancreatic tumor cells show a very high frequency of p53 mutation. to determine if restoration of wild type p53 function can be used to eliminate the tumorigenic phenotype in these cells, pancreatic tumor cell lines, panc-1 and htb80, differing in p53 status were stably transfected with exogenous wil...

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...

The photoredox cycle oxidizes 1 to cyanogen 2 and generates associated reducing power in the form of protons and hydrated electrons, which reduce further 1 to formaldehyde imine 3. Hydrolysis of 3 to formaldehyde 4 is then followed by addition of 1 to give glycolonitrile 5. Iteration of this process results in the sequential production of glycolaldehyde 6, its cyanohydrin 7, and glyceraldehyde ...

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...
