Previous studies showed that the meme popularity distribution is described by a heavy-tailed distribution or a power-law, which is a characteristic feature of the criticality. Here, we study the origin of the criticality on non-growing and growing networks based on the competition induced criticality model. From the direct Mote Carlo simulations and the exact mapping into the position dependent...

The anticancer ruthenium complex trans-[tetrachlorobis(1Hindazole)ruthenate(III)], otherwise known as KP1019, has previously been shown to inhibit proliferation of ovarian tumor cells, induce DNA damage and apoptosis in colon carcinoma cells, and reduce tumor size in animal models. Notably, no doselimiting toxicity was observed in a Phase I clinical trial. Despite these successes, KP1019’s prec...

Pennsylvania generates over 50,000 m of spent mushroom substrate (SMS) annually due to production of the white button mushroom Agaricus bisporus (Chong and Hamersma 1997). Improper disposal of this volume of organic waste may cause environmental problems such as air, water and soil pollution. Considering that its major ingredients include incompletely composted straw, hay, manure, gypsum and po...

We have performed a genome-wide analysis of common genetic variation controlling differential expression of transcript isoforms in the CEU HapMap population using a comprehensive exon tiling microarray covering 17,897 genes. We detected 324 genes with significant associations between flanking SNPs and transcript levels. Of these, 39% reflected changes in whole gene expression and 55% reflected ...

BACKGROUND Carbohydrate antigen 15-3 (CA15-3), Kerbs von den Lungen (KL-6) and breast cancer antigen 225 (BCA225) are widely used tumor markers for breast and lung cancer respectively. PATIENTS AND METHODS We analyzed 460 Japanese volunteers for 99 items on blood examination including 27 serum tumor markers. Correlations between 27 tumor markers and the other items were statistically analyzed...

We are witnessing a global financial and economic crisis, which may have far-reaching, and at least recently, unforeseeable consequences on the future and development of world science and technology. Control theory has always been an area of science driven by technology. From the statistical filtering solution formulated by R. Kalman in the early 1960s, devised for answering the needs of NASA's...

Although personalised nutrition is frequently considered in the context of diet–gene interactions, increasingly, personalised nutrition is seen to exist at three levels. The first is personalised dietary advice using Internet-delivered services, which ultimately will become automated and which will also draw on mobile phone technology. The second level of personalised dietary advice will includ...

Chemical recovery of many anthropogenically acidified waters is occurring in Europe and North America in response to recent pollution reductions (1). These chemical improvements are particularly dramatic and well-described for the Sudbury, Ontario, Canada region including the lakes in Killarney Park (2, 3). From lakes in the Sudbury region there is also considerable evidence of natural recovery...
