International Journal of Cancer, EarlyView.ABSTRACT The standard for assessing and recording the extent of the tumour, a necessity for most malignancies, is the Tumour Node Metastases (TNM) classification. The Union for International Cancer Control (UICC) TNM committee has defined this since the early 1950s.

Five-point form of the nodal diffusion method and comparison with finite-difference [PDF]
, 1988 Nodal Methods have been derived, implemented and numerically tested for several problems in physics and engineering. In the field of nuclear engineering, many nodal formalisms have been used for the neutron diffusion equation, all yielding results which ...

iRADIOLOGY, EarlyView.For patients with diffuse component, the presence of bulky disease and spleen involvement is strongly predictive of BMB‐confirmed BMI. Conversely, the absence of PET/CT‐detected BMI, bulky disease, and splenic involvement suggests a low likelihood of BMB‐confirmed BMI.

Errors associated with standard nodal diffusion methods as applied to mixed oxide fuel problems [PDF]
, 1998 The evaluation of the disposition of plutonium using light water reactors is receiving increased attention. However, mixed-oxide (MOX) fuel assemblies possess much higher absorption and fission cross- sections when compared to standard UO2 assemblies ...
