A method is described for the formation of stable, composite aqueous emulsions of 1) combinations of distinct families of bubbles of nitrogen, 2) combinations of distinct families of droplets of an organic fluid (either perfluoro(methyl)decalin or hexadecane), and 3) combinations of bubbles and droplets. A system of two or three microfluidic flow-focusing units is coupled to a single outlet cha...

Quantum dots form equilibrium structures in liquid dispersions, due to thermodynamic forces that are often hard to quantify. Analysis of these structures, visualized using cryogenic electron microscopy, yields their formation free energy. Here we show that the nanoparticle interaction free energy can be further separated into the enthalpic and entropic contributions, using the temperature depen...

On-line two-angle (15 and 90) light scattering measurements with a gel permeation chromatograph for linear and branched polystyrene in tetrahydrofuran (a good solvent) and in trans-decalin (a theta solvent) were made and compared with data from a multi-angle light scattering detector and literature values. Theoretically, weight-average molecular weight and the radius of gyration Rg can be det...

Background: Development of an effective vaccine is highly needed in order to restrict the AIDS pandemic. DNA vaccines initiate both arms of immunity without the potential of causing disease. HIV-1 p24 and gp41 (gag and env) proteins play important roles in viral pathogenesis and are effective candidates for immune induction and vaccine design. Objective: In this study, new DNA vaccine candidate...

A single precision floating-point fused add-subtract unit and fused dot-product unit is presented that performs simultaneous floating-point add and multiplication operations. It takes to perform a major part of single addition, subtraction and dot-product using parallel implementation. This unit uses the IEEE-754 single-precision format and supports all rounding modes. The fused add-subtract un...

Background: To retrospectively describe imaging characteristics of liver metastases on fused FDG-PET/ MRI data sets and to compare the diagnostic accuracy of MRI and fused FDG-PET/MRI data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. Materials and Methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by FDG-PET...
