The dynamic density functional (DDF) theory and standard Brownian dynamics simulations (BDS) are used to study the drifting effects of a colloidal particle in a polymer solution, both for ideal and interacting polymers. The structure of the stationary density distributions and the total induced current are analyzed for different drifting rates. We find good agreement with the BDS, which gives s...

Sequences based on the distant dipolar field (DDF) have shown great promise for novel spectroscopy and imaging. Unless spatial variation in the longitudinal magnetization, Mz(s), is eliminated by relaxation, diffusion, or spoiling techniques by the end of a single repetition, unexpected results can be obtained due to spatial harmonics in the steady state MzSS(s) profile. This is true even in a ...

Dataflow process networks are a special case of Kahn process networks (PN). In dataflow process networks, each process consists of repeated firings of a dataflow actor, which defines a quantum of computation. Using this quantum avoids the complexities and context switching overhead of process suspension and resumption incurred in most implementations of Kahn process networks. Instead of context...

The DDF (Distributed Data Facility) environment provides the capability for remote access to large DB2 databases by many remote application servers. While much of the application activity occurs outside the zseries complex, there are many measurements that can be used to understand not only the internal but also the remote activity that drives performance and capacity. This paper will explore t...

This study examined whether gardening modifies the association between age and body mass index (BMI). We used data from the Neighborhood Environments and Health Survey, which was conducted in Denver (N = 469) between 2006 and 2007. We fit two general linear mixed models. The base model had BMI in kg/m2 as the outcome, and age, an indicator variable for non-gardening status and the age-by-non-ga...

This demonstration presents a debugging framework that targets domain-specific languages (DSLs). The DSL Debugging Framework (DDF) generates debuggers automatically from DSL grammar specifications. The debugging concern is weaved into a base grammar in an aspect-oriented style. DDF was used to generate debuggers for three different types of DSLs (imperative, declarative, and hybrid) that are tr...

Subpopulations of patients with adjustment disorder are at increased risk for suicide. The current study investigated whether personality traits, including alexithymia, temperament, and character, are associated with an increased risk of suicide in individuals with adjustment disorder. Age- and sex-matched patients meeting the diagnostic and statistical manual of mental disorders (DSM-IV) crite...

Fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) are the most common methods that are used to quantify HER-2 gene and protein levels, respectively, in human breast cancer. However, due to bad sample quality, some samples are unable to be subjected to a FISH assay. We evaluated 71 formalin-fixed paraffin-embedded (FFPE) breast carcinoma specimens by quantitative real-time ...
