The mean nuclear area, maximum nuclear diameter (Dmax) and form factor (FF) have been measured in 30 specimens of non-Hodgkin's lymphoma (NHL) and 10 reactive lymph nodes, using the Reichert-Jung (Kontron) MOP-AMO3 image analyzer. Nuclear area and Dmax were found to be greater in high-grade NHL than in low-grade lymphomas and reactive nodes. In addition, there was close correlation between nucl...

Given an edge weighted tree T and two non-negative real numbers dmin and dmax, a pairwise compatibility graph of T for dmin and dmax is a graph G = (V, E), where each vertex u ∈ V corresponds to a leaf u of T and there is an edge (u, v) ∈ E if and only if dmin ≤ dT (u, v) ≤ dmax in T . Here, dT (u, v) denotes the distance between u and v in T , which is the sum of the weights of the edges on th...

In a series of nine experiments, observers were required to identify the shapes of moving targets, and to discriminate regions of motion from regions of uncorrelated noise. Maximum displacement thresholds (Dmax) for performing these tasks were obtained under a wide variety of conditions. The stimulus parameters manipulated included the number of distinct frames in the motion sequences, the stim...

Let T be an edge weighted tree, let dT (u, v) be the sum of the weights of the edges on the path from u to v in T , and let dmin and dmax be two non-negative real numbers such that dmin ≤ dmax. Then a pairwise compatibility graph of T for dmin and dmax is a graph G = (V, E), where each vertex u ∈ V corresponds to a leaf u of T and there is an edge (u, v) ∈ E if and only if dmin ≤ dT (u, v) ≤ dm...

PURPOSE To investigate whether a spaced-education (SE) game can be an effective means of teaching core content to medical students and a reliable and valid method of assessing their knowledge. METHOD This nine-month trial (2008-2009) enrolled students from three U.S. medical schools. The SE game consisted of 100 validated multiple-choice questions-explanations in preclinical/clinical domains....

Maximum motion displacement (Dmax) is the largest dot displacement in a random-dot kinematogram (RDK) at which direction of motion can be correctly discriminated [Braddick, O. (1974). A short-range process in apparent motion. Vision Research, 14, 519-527]. For first-order RDKs, Dmax gets larger as dot size increases and/or dot density decreases. It has been suggested that this increase in Dmax ...

BACKGROUND To investigate the potential mechanism of splenic enlargement in Ang II/APOE model and the associations between the spleen volume and the indices of abdominal aortic aneurysm (AAA) in human. METHODS To investigate the changes of spleen volume on AAA formation, apolipoprotein E knockout (Apo E-/-) mice were treated with Ang II (1000 ng/kg/min) up to 28 days to generate AAA. We used ...

A graph G = (V, E) is called a pairwise compatibility graph (PCG) if there exists a tree T , a positive edge-weight function w on T , and two non-negative real numbers dmin and dmax, dmin ≤ dmax, such that V coincides with the set of leaves of T , and there is an edge (u, v) ∈ E if and only if dmin ≤ dT,w(u, v) ≤ dmax where dT,w(u, v) is the sum of the weights of the edges on the unique path fr...
