snn = 17GeV a sudden increase in the pion source volume is observed for central PbPb collisions. This seems to imply that the pion phase density has reached a limit. The source size of different particles decreases with mass when the transverse velocity is held constant but increases with mass when mT is held constant. The antiproton source radius is larger than the proton source radius. So far...

Trabecular or cancellous bone is a major element in the structural design of the vertebrate skeleton, but has received little attention from the perspective of the biology of scale. In this study, we investigated scaling patterns in the discrete bony elements of cancellous bone. First, we constructed two theoretical models, representative of the two extremes of realistic patterns of trabecular ...

according to its superficial anatomical location, the thyroid gland is easily accessible by sonography. sonography allows an exact documentation of the size and thyroid volume. the relationship between thyroid volume and anthropometric characteristics is a matter of controversy. the aim of this study was to investigate thyroid volume and its determinants in healthy adult. a cross-sectional stud...

We study the form factor of thermoresponsive microgels based on poly(N-isopropylacrylamide) at high generalized volume fractions, ζ, where the particles must shrink or interpenetrate to fit into the available space. Small-angle neutron scattering with contrast matching techniques is used to determine the particle form factor. We find that the particle size is constant up to a volume fraction ro...

Budding yeast cells are assumed to trigger Start and enter the cell cycle only after they attain a critical size set by external conditions. However, arguing against deterministic models of cell size control, cell volume at Start displays great individual variability even under constant conditions. Here we show that cell size at Start is robustly set at a single-cell level by the volume growth ...

We study the graph partitioning problem on ddimensional ball graphs in a geometric way. Let B be a set of balls in d-dimensional Euclidean space with radius ratio δ and λ-precision. We prove that it can be partitioned into three sets BS , BI , BE such that the intersection of BI and BE is empty, and for some constant α, the volume of BI and BE is less than α portion of volume of B, and the volu...

We consider a growth medium with an infinite volume and a constant substrate concentration S in which cells are growing. The total biomass of these cells increases exponentially. During balanced growth, in an exponentially growing system, every extensive variable X , like total pools of cellular components, total intracellular volume, total membrane surface etc., increases in time (t) with the ...
