Background Color Doppler flow mapping is widely used as a marker of severity of valvular regurgitation, and the transesophageal approach has provided high-quality images in patients with poor acoustic windows. However, different instruments produce significantly variable images. Techniques that use jet spatial information to determine the severity of the lesion may need to be derived specifical...

This indirect method for determination of desferrioxamine (DFO, deferoxamine, Desferal) and its chelated compounds ferrioxamine (FO) and aluminoxamine (AIO) in biological fluids involves metal chelate formation and solvent extraction, the metal being determined by Zeeman atomic absorption spectrometry (Zeeman-AAS). Special attention was paid to the pH and recovery of extraction, iron-aluminum i...

This study compared emotion perception accuracy between children with Asperger's syndrome (AS) and high-functioning autism (HFA). Thirty children were diagnosed with AS or HFA based on empirically supported diagnostic criteria and administered an emotion perception test consisting of facial expressions and tone of voice cues that varied in intensity. Participants with AS and the typically devel...

Mobile-phones have facilitated the creation of field-portable, cost-effective imaging and sensing technologies that approach laboratory-grade instrument performance. However, the optical imaging interfaces of mobile-phones are not designed for microscopy and produce spatial and spectral distortions in imaging microscopic specimens. Here, we report on the use of deep learning to correct such dis...

Clinical flow cytometry has evolved from two-parameter quantitative assessment of peripheral blood lymphocytes to six-parameter qualitative evaluation of bone marrow for hematopathology. Leukemia and lymphoma immunophenotyping represent an extremely important complement to morphology in the diagnosis and monitoring of hematopoietic malignancies. The complexity of five- and six-parameter analyse...

This study is an exploration of teachers’ engagement with concepts embedded in the normal distribution. The participants were a group of 290 in-service teachers enrolled in a teacher development program. The research instrument was an assessment task that can be described as an “unknown percentage” problem, which required the application of properties of the standard normal distribution curve. ...

The standardization of worldwide interoperability for microwave access (WiMAX) represents an opportunity for a radical shift in viewing the Internet and its access systems. Considering the current constellation of the Internet service providers (ISPs), WiMAX can both improve its presence (by offering broadband connectivity where previously unavailable) and trim down its authority (if used as an...

To introduce some measure of standardization in the face of the endless variety of whiteness formulas being used, the "Commission internationale de l'éclairage" proposed in 1986 a whiteness and a tint formula for practical trials. The formulas in question were simplified derivatives of those used in the Ganz/Griesser method. The difference is that the CIE proposes fixed formula parameters and r...

Synchrotron radiation circular dichroism (SRCD) is an emerging technique in structural biology with particular value in protein secondary structure analyses since it permits the collection of data down to much lower wavelengths than conventional circular dichroism (cCD) instruments. Reference database spectra collected on different SRCD instruments in the future as well as current reference dat...

In the R&D community there is a growing awareness of the importance of benchmarking. Benchmarks not only allow comparing performance of different technologies, devices, and algorithms, but also define and thereby boost R&D targets and directions, and are an important support to standardization and regulation procedures towards market introduction. Benchmarking has been recently considered by th...
