We systematically analyze three GRB samples named as radio-loud, radio-quiet and radio-none afterglows, respectively. It is shown that dichotomy of the radio-loud afterglows not necessary. Interestingly, we find intrinsic durations ($T_{int}$), isotropic energies prompt gamma-rays ($E_{\gamma, iso}$) redshifts ($z$) their host galaxies are log-normally distributed for both except those GRBs wit...

In this paper we describe a new approach to programming which generalizes object-oriented programming. It is based on using a new programming construct, called concept, which generalizes classes. Concept is defined as a pair of two classes: one reference class and one object class. Each concept has a parent concept which is specified using inclusion relation generalizing inheritance. We describ...

In this column, the author outlines some of the results of the Listening to Mothers Survey, conducted by the Maternity Center Association, and the implications of the results on childbirth education.

In April 2010 the International Finance Corporation announced the creation of the African, Latin American, and Caribbean fund, a new co-investment vehicle funded largely with commitments from sovereign wealth and pension funds. The fund’s objective was to draw on the IFC and the World Bank’s strengths in emerging markets to identify and support enterprises that might not otherwise have come to ...

For a bar and joint framework (G, p) with point group C3 which describes 3-fold rotational symmetry in the plane, it was recently shown in (Schulze, Discret. Comp. Geom. 44:946-972) that the standard Laman conditions, together with the condition derived in (Connelly et al., Int. J. Solids Struct. 46:762-773) that no vertices are fixed by the automorphism corresponding to the 3-fold rotation (ge...

Two homologous series of cyclically twinned sulphosalt structures are defined in the present paper, with different atomic configurations around the site of sixand threefold axes. The zinckenite homologous series, M6+x+N(N+S) A12+N(N+7), contains zinckenite, a Pb-Sb sulphosalt, and sulphohalogenides of Bi and Pb. The Ba Bi sulphide homologous series, M12+x+N(N+S) A18+N(N+7), contains complex sul...

THERMUS is a package of C++ classes and functions allowing statistical-thermal model analyses of particle production in relativistic heavy-ion collisions to be performed within the ROOT framework of analysis. Calculations are possible within three statistical ensembles; a grand-canonical treatment of the conserved charges B, S and Q, a fully canonical treatment of the conserved charges, and a m...

BACKGROUND Childbirth fear is reported to affect around 20% of women. However reporting on levels of symptom severity vary. Unlike Scandinavian countries, there has been limited focus on childbirth fear in Australia. The aim of this paper is to determine the prevalence of low, moderate, high and severe levels of childbirth fear in a large representative sample of pregnant women drawn from a lar...
