Beginning with the category Dom of Scott domains and continuous maps, we introduce a syntax for dataaow networks as \systems of inequalities," and provide an associated operational semantics. We observe that, under this semantics, a system of inequalities determines a two-sided bration in Dom. This leads to the introduction of a certain class of cartesian arrows of spans as a notion of morphism...

Fragile sites /Chromosomal aberrations play a role in the etiology of mental retardation and other associated complications. Since Down syndrome is the most common genetic cause of mental retardation, the present study was done to evaluate the effect of fragile sites on sys-temic diseases and growth and developmental pattern among them. Human lymphocyte cell culture with folate free medium show...

Attempts to maintain or expand primitive hematopoietic stem cells in vitro without the concomitant loss of their differentiative and proliferative potential in vivo have largely been unsuccessful. To investigate this problem, we compared the ability of three cloned bone marrow (BM) stromal cell lines to support the growth of primitive Thy-1lo Sca-1+H-2Khi cells isolated by fluorescence-activate...

Using 6.32 fb$^{-1}$ of $e^+e^-$ collision data collected by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV,~an amplitude analysis $D^{+}_{s}\rightarrow K^{0}_{S}K^{-}\pi^{+}\pi^{+}$ decays is performed for first time to determine intermediate-resonant contributions. The dominant component $D_s^+ \to K^*(892)^+\overline{K}^*(892)^0$ decay with a fraction $(40.6\pm2.9...

This paper investigates the internationalisation decision-making process from perspective of decision maker's cognition. The aim is to advance theoretical arguments that help explain heterogeneous patterns for smaller ventures. Our framework includes four-stage psychological - perception, options, evaluation and choice under interactive effect two cognitive systems, namely experiential (Sys-1) ...

Let $$X \subset {\mathbb {R}}^4$$ be a convex domain with smooth boundary Y. We use relation between the extrinsic curvature of Y and Ruelle invariant Reeb flow on to prove that there are constants $$C> c > 0$$ independent such $$\begin{aligned} \leqslant {\text {ru}}(Y) \cdot {sys}}(Y)^{1/2} C \end{aligned}$$ Here $${\text {sys}}(Y)$$ is systolic ratio Y, i.e. square minimal period closed orbi...
