the transplanted spleens attains the mass of one normal “The most obvious differences between different aniadult spleen, suggesting that their growth is mainly conmals are differences in size, but for some reason the trolled by factors outside the spleen (Metcalf, 1964). zoologists have paid singularly little attention to them.” Similar transplantation experiments, as well as tissue —J. B. S. H...

Cell size is an important adaptive trait that influences nearly all aspects of cellular physiology. Despite extensive characterization of the cell-cycle regulatory network, the molecular mechanisms coupling cell growth to division, and thereby controlling cell size, have remained elusive. Recent work in yeast has reinvigorated the size control field and suggested provocative mechanisms for the ...

Locality and storage management considerations for fork-join parallelism lead to the loss of the important List Scheduling property. The worst case performance of the constrained scheduling policies, called PaH and ToS, is very bad: (nearly) all parallelism is lost. “Practical” performance, however, differs radically from worst case performance. The PaH and ToS policies perform on average withi...

Like eukaryotes, bacteria must coordinate division with growth to ensure cells are the appropriate size for a given environmental condition or developmental fate. As single-celled organisms, nutrient availability is one of the strongest influences on bacterial cell size. Classic physiological experiments conducted over four decades ago first demonstrated that cell size is directly correlated wi...

In the present investigation, a systematic study on the dependence of chelating agents on the size control of silver phosphate Ag3PO4 powders is presented. The effect of two different capping-ligands (monoethanolamine (MEA) and oleylamine (OLA) as amino-additives) is studied using sol-gel route. Structural and morphological characterization techniques were used to quantify...
