This paper explains the studies of recent years on development of EPR system and the project risk and then illustrates respectively the external risks and internal risks of EPR project based on the theory. Taking the EPR project of G company the author actually took part in as an example, the author firstly applies fuzzy evaluating method to evaluate project risks and draw a clear distinction b...

A recent survey of nonlinear continuous-wave (CW) EPR methods revealed that the first-harmonic absorption EPR signal, detected 90 degrees out of phase with respect to the Zeeman modulation (V(1)(')-EPR), is the most appropriate for determining spin-lattice relaxation enhancements of spin labels (V. A. Livshits, T. Páli, and D. Marsh, 1998, J. Magn. Reson. 134, 113-123). The sensitivity of such ...

Electron Paramagnetic Resonance (EPR) is a spectroscopic technique that detects and characterizes molecules with unpaired electrons (i.e., free radicals.) Unlike the closely related nuclear magnetic resonance (NMR) spectroscopy, EPR is still under development as an imaging modality. Athough a number of physical factors have hindered its development, EPR’s potential is quite promising in a numbe...

Malignant melanoma is a tumor characterized by the uncontrolled proliferation of melanocytes, mainly in skin, but also in eyes. Its incidence is rising each year. To improve the diagnosis and treatment of the tumor, it is essential to develop new effective methods to early detect and characterize melanoma. Previously, we demonstrated in a single-shot study that it was possible to map free radic...

Einstein-Podolsky-Rosen (EPR) steering describes the ability of one observer to nonlocally "steer" the other observer's state through local measurements. EPR steering exhibits a unique asymmetric property; i.e., the steerability can differ between observers, which can lead to one-way EPR steering in which only one observer obtains steerability in the steering process. This property is inherentl...

Background: In light of plans to implement an electronic patient record (EPR), preparations for radical organisational change were recognised as being critical to success. Aim: To determine hospital staff’s experience of and attitudes toward computer use and the EPR. Method: A cross-sectional design using The Computer and EPR Attitude Survey was administered to 878 health service employees in t...
