Aims—To investigate the expression of â-catenin in non-small-cell lung cancer (NSCLC) and its clinical significance. Methods—101 patients were surgically treated for NSCLC by lobectomy or pneumectomy with systematic lymph node dissection. Follow up was available in all patients, ranging from 24 to 110 months. Immunostaining of tissue sections from primary tumours and (when present) their lymph ...

â â â â â â â  this paper proposes a new forecasting model for investigating relationship between the price of crude oil, as an important energy source and gdp of the us, as the largest oil consumer, and the uk, as the oil producer. gmdh neural network and mlff neural network approaches, which are both non-linear models, are employed to forecast gdp responses to the oil price changes. the resul...

Recently, evidence was reported for the belief that a carcinogenic agent, †̃20-methyleholanthrene, could be secreted into the milk of a lactating ani mal and thereby gain entrance into the bodies of the offspring to cause an abnormally high mci dence of neoplasms (1). Further positive evidence for this mode of excretion of methyleholanthrene has now been obtained by means of ultraviolet ab sor...

A one-parameter symplectic group {e}t∈R derives proper canonical transformations on a Boson Fock space. It has been known that the unitary operator Ut implementing such a proper canonical transformation gives a projective unitary representation of {e}t∈R and that Ut can be expressed as a normal-ordered form. We rigorously derive the self-adjoint operator ∆(Â) and a phase factor e i ∫ t 0 τ Â (s...

The Chow ring of a smooth algebraic variety V , denoted CH∗(V ), is an analogue of the cohomology ring that is more closely related to the algebraic, rather than topological, aspects of the variety. For a d-dimensional abelian variety A over a field k, let  = Pic(A) be its dual, the variety parameterising principal line bundles on A, and for a ∈  denote the line bundle parameterised by a as L...
