The acronym VACTERL describes the non-random co-occurrence of three of the following anomalies: vertebral (V), anal (A), cardiac (C), tracheoesophageal fistula with or without oesophageal atresia (TE), renal (R) and limb defects (L). Here, we report a newborn baby with VACTERL-type anomalies along with a single umbilical artery. The additional interesting findings include development dysplasia ...

Let Yl, , Yp be monomials over the indeterminates Xl, , xq. For every y (yl, , yp) there is some minimum number L(y) of multiplications sufficient to compute y 1, , Yo from x 1, , xq and the identity 1. Let L(p, q, N) denote the maximum of L(y) over all y for which the exponent of any indeterminate in any monomial is at most N. We show that if p (N+ 1) () and q (N+ 1)(), then L(p, q, N) min {p,...

The origin of the Xq21.3/Yp regions of homology in Homo sapiens by a reduplicative translocation dated at between 3 and 2 million years BP and a subsequent (and presently undated) paracentric inversion that split the translocated block on a hominid Y short arm. Adapted from Schwartz A. et al (Reconstructing hominid Y evolution: X-homologous block, created by XY transposition, was disrupted by Y...

Positive-definite means that gp(v, v) > 0 for every v 6= 0, v ∈ TpM . Smoothly depending on p means that for every pair Xp,Yp of C ∞-smooth vector fields on M the expression gp(Xp, Yp) defines a C ∞-smooth function of p ∈M . Alternatively, consider a coordinate neighbourhood on M containing p and let x, i = 1, . . . , dimM be the local coordinates. Then any two tangent vectors u, v ∈ TpM may be...

A reanalysis is made for the helium abundance determination for the Izotov-Thuan (2004) spectroscopic sample of extragalactic H II regions. We find that the effect of underlying stellar absorption of the He I lines, which is more important for metal poor systems, affects significantly the inferred primordial helium abundance Yp obtained in the zero metallicity limit and the slope of linear extr...

We present .a study of the decay sequence J/w + yX, X-+ yp', p "-+ rr+rr-, _. based on 5.8 x lo6 produced J/i) collected by the Mark III detector at SPEAR. In the yp " mass spectrum, we find two peaks with masses and widths consistent with the axial vector mesons ji(1285) and ji(1420) that have recently been observed in two-photon collisions. Fits to the angular distributions confirm that the f...

In this study, we aimed to assess how sample sizes affect confidence of stand-scale transpiration (E) estimates calculated from sap flux (F(d)) and sapwood area (A(S_tree)) measurements of individual trees. In a Japanese cypress plantation, we measured F(d) and A(S_tree) in all trees (n = 58) within a 20 x 20 m study plot, which was divided into four 10 x 10 subplots. We calculated E from stand...

The percolation problem is solved exactly in one dimension. The functions obtained bear a strong resemblance to those of the n-vector model on the same lattice. Further, we include a ghost field exactly in all dimensions d, thereby treating the ‘thermodynamics’ of percolation without appealing to the Potts model. In particular, we show for d = 1 that the nature of the singularities near the cri...
