We present a number of jet fragmentation measurements in ee ! hadrons. The ALEPH collaboration measures inclusive (770), f0(980) and f2(1270) production rates, improving the world averages. The SLD collaboration measures , K and p/ p production in light-, cand bavor Z decays, as well as leading hadrons in light-quark jets, precisely. The DELPHI collaboration measures the average charged multipl...

We calculate the branching ratios of B → K1γ at next-to-leading order (NLO) of αs where K1 is the orbitally excited axial vector meson. The NLO decay amplitude is divided into the vertex correction and the hard spectator interaction part. The one is proportional to the weak form factor of B → K1 transition while the other is a convolution between light-cone distribution amplitudes and hard scat...

This paper provides a time-series analysis of recent annual estimates of real GDP and industrial output covering 1270 to 1913. We show that growth can be regarded as a segmented trend stationary process. On this basis, we find that trend growth of real GDP per person was zero prior to the 1660s but then experienced two significant accelerations, preand post-industrial revolution. We also find t...

In the 40 years since Harvard medical student Gilbert Omenn first described a rare, inherited disorder producing a paradoxical combination of immunodeficiency and immune dysregulation, the pathogenesis of Omenn syndrome (OS) has remained mysterious. In separate studies reported in this issue of the JCI, two mouse models bearing mutations in the V(D)J recombinase analogous to those causing human...

The sum-connectivity index R′(G) of a graph G is the sum of the weights (du +dv) − 2 of all edges uv of G, where du and dv are the degrees of the vertices u and v in G. This index was recently introduced in [B. Zhou, N. Trinajstić, On a novel connectivity index, J. Math. Chem. 46(2009), 1252–1270]. In this paper, we give the sharp lower bound of the sum-connectivity index of n-vertex unicyclic ...

Chronic illness in children may negatively affect aspects of health-related quality of life (HRQL). Over many years, camps have been organized to address the physical and psychosocial needs of children with various chronic illnesses, while providing a "normal" as possible camp experience. The aim of this study was to critically review all research examining the effect of camps on HRQL in childr...
