This paper studies platform ecosystems, a novel business entity built upon a platform coordinating the interactions between suppliers and users, particularly in the IT service sectors. Borrowing words from two core firm theories resource-based view (RBV) and transaction cost view (TCV), we propose that the platform ecosystem works at the boundary between “market and hierarchy.” To show this, ...

This work presents a quantitative test of SOLPS-ITER simulations against tokamak à configuration variable (TCV) L-mode experiments. These account for drifts, currents, kinetic neutrals, and carbon impurities providing the most complete edge transport TCV to date. The comparison is performed on nominally identical discharges carried out assess effectiveness TCV's divertor baffles in framework Eu...

BACKGROUND As children with velocardiofacial syndrome (VCFS) develop, they are at increased risk for psychopathology; one third will eventually develop schizophrenia. Because VCFS and the concomitant symptomatology result from a known genetic origin, the biological and behavioral characteristics of the syndrome provide an optimal framework for conceptualizing the associations among genes, brain...

Extensive karyotype analysis including determination of somatic chromosome number, total chromosome length and volume and estimation of 4C DNA content were carried out on three species of Pachypodium namely P. lamerei; P. namaquanum and p rosulatum ' horombense' for the first time. A significant variation in nuclear DNA amount was recorded at interspecific level. The somatic chromosome number 2...

Molecular mechanisms of RNA recombination were studied in turnip crinkle carmovirus (TCV), which has a uniquely high recombination frequency and non-random crossover site distribution among the recombining TCV-associated satellite RNAs. To test the previously proposed replicase-driven template-switching mechanism for recombination, a partially purified TCV replicase preparation (RdRp) was progr...

T cell vaccination (TCV) is a method to induce resistance to autoimmune diseases by priming the immune system with autoreactive T cells. This priming evokes an anti-idiotypic regulatory T cell response to the receptors on the autoreactive T cells. Hence resistance is induced. To prevent the inoculated autoreactive cells from inducing autoimmunity, cells are given in a subpathogenic dose or in a...

Transient expression of proteins in plants has become a choice to facilitate recombinant protein production with its fast and easy application. On the other hand, host defensive mechanisms have been reported to reduce the efficiency of transient expression in plants. Hence, this study was designed to evaluate the effect of cap analog and Potato virus A helper component proteinase (PVA HC-Pro) o...

Objective. Systemic lupus erythematosus (SLE) is an autoimmune disease identified by a plethora of production of autoantibodies. Autoreactive T cells may play an important role in the process. Attenuated T cell vaccination (TCV) has proven to benefit some autoimmune diseases by deleting or suppressing pathogenic T cells. However, clinical evidence for TCV in SLE is still limited. Therefore, thi...

The 3' ends of RNAs associated with turnip crinkle virus (TCV), including subviral satellite (sat)C, terminate with the motif CCUGCCC-3'. Transcripts of satC with a deletion of the motif are repaired to wild type (wt) in vivo by RNA-dependent RNA polymerase (RdRp)-mediated extension of abortively synthesized oligoribonucleotide primers complementary to the 3' end of the TCV genomic RNA. Repair ...

We report a case of colonic volvulus in a 7-year-old child with normal development. Operative findings at laparotomy showed a 270-degree transverse colonic volvulus (TCV), with colonic ligamentous attachment abnormalities. A loop ileostomy was formed following detorsion, with delayed laparoscopic colopexy. This is the first case to describe decompression by diversion ileostomy as acute manageme...
