Ha, M and Michaelis, V.K.

Dynamic nuclear polarization (DNP) NMR spectroscopy, a high-polarization method, is rapidly changing the landscape of what is possible in solid-state nuclear magnetic resonance spectroscopy. To date, there have been over 200 publications discussing high-frequency DNP NMR of solids with more than...

High-frequency dynamic nuclear polarization nuclear magnetic resonance (DNP NMR) spectroscopy is having a major impact on the far-reaching abilities of solid-state NMR. This high-sensitivity technique made possible by transferring high polarization from an unpaired electron source to an...

As an advanced fracture model, the Generalized Incremental Stress State dependent damage MOdel (GISSMO) provides non-linear damage accumulation formulation to better predict ductile fracture initiation associated with a wider range of material stress states. In this study, we simulate the...

Short-term and long-term population growth rates can differ considerably. While changes in growth rates can be driven by external factors, we consider another source for changes in growth rate. That is, changes are generated internally by gradual modification of population structure. Such...

Back-slopping of fermentation cultures in food fermentations can ensure stability of fermentation microbiota at the species or even at the strain level over extended periods of time. In contrast to the fermentation organisms in spontaneous food fermentations, which are derived from...

Labor productivity and performance both significantly influence the overall success of construction projects, and the motivation of crew members is a major factor affecting labor. The construction industry needs better methods of measuring motivation and its impact on performance, which in turn...

The emigration of sub-Saharan African health professionals to developed Western nations is an aspect of increasing global mobility. This paper focuses on the human resources for health challenges in Nigeria and the emigration of nurses from Nigeria as the country faces mounting human resources...

The majority of competency and performance modeling methods available in the literature are deterministic conceptual, statistical,and/or regression models that cannot capture the subjective uncertainty, complex, and nonlinear relationships inherent in construction, whichmakes accurate prediction...

Traditional risk analysis techniques are ineffective for capturing the dynamic causal interactions and subjective uncertainties involved in assessing risk and opportunity events since they treat risks independently and rely on the availability of sufficient historical data. In this paper, a...
