BACKGROUND Therapeutic effect of stem cell transplantation (SCTx) for myocardial neovascularization has been evaluated by histological capillary density in small animals. However, it has been technically difficult to obtain imaging evidence of collateral formation by conventional angiography. METHODS AND RESULTS Peripheral blood CD34+ and CD34- cells were isolated from patients with critical ...
We discuss the problem of partitioning a set of points into two subsets with certain conditions on the diameters of the subsets and on their cardinalities. For example, we give an O(n log n) algorithm to find the smallest t such that the set can be split into two equal cardinality subsets each of which has diameter at most t. We also give an algorithm that takes two pairs of points (x, y) and (...
The transfinite diameter is a way of quantifying the size of compact sets in Euclidean space. This quantity is related to the Hausdorff dimension and the Lebesgue measure, but gives a slightly different perspective on the set than either of those do. In this paper, we introduce the transfinite diameter, and outline some attempts to calculate this quantity for three sets in R. For z1, z2, . . . ...
BACKGROUND The inferior vena cava (IVC) parameters, including its diameter and collapsibility index have been evaluated for fluid status for over 30 years, but little is known about the impacts of patient characteristics on IVC parameters. The purpose of this study was to explore the relationships between individual patient characteristics and IVC parameters in healthy Chinese adult volunteers....
PURPOSE To evaluate the relationship between the horizontal ciliary sulcus diameter and anterior chamber diameter measured by 35 MHz ultrasound biomicroscopy (UBM) and the horizontal corneal diameter (white to white [WTW]) measured by scanning-slit topography and to assess the repeatability (intraexaminer difference) of the 2 methods. SETTING Department of Orthoptics and Visual Science, Kitas...
Selective Laser Melting is an efficient process for producing metal parts with minimal subtractive post-processing required. Analysis of the parameters controlling the part quality has been performed focussing on the energy intensity during processing and the effect of the particle size distribution on factors such as ultimate tensile strength and surface finish. It is shown that the controllin...
Nanoposts of 10–40 nm top diameter on an InGaN/GaN quantum well structure were fabricated using electron-beam lithography and inductively coupled plasma reactive ion etching. Significant blue shifts up to 130 meV in the photoluminescence (PL) spectrum were observed. The blue-shift range increases with decreasing post diameter. For nanoposts with significant strain relaxation, the PL spectral pe...
This ar t ic le i s an in troduct ion to the computevsoffwave used by the Potential Relative Increment (PRI) approach to opt imal tree diameter growth modeling. These DOSpvograms extract quali f ied tree andplot data,from the Eastwide Forest Inventory Data Base (EFIDB), calculate relat ive tree increment , sort for the highest relat ive iucrements by diameter class, and generate an ASCIIjile fo...
