Mature Fine Tailings (MFT) generated from oil sands processing represent a growing environmental issue, as settling of these tailings’ emulsion can take decades, increasing the risk toxic material’s leaching if left untreated. This study uses advanced wet air oxidation (WAO) and peroxide (WAPO) to break down MFT emulsions for faster settling. Three time intervals (5, 15, 30 min) were investigat...

BACKGROUND/AIMS Survivin, a member of the inhibitor of apoptosis protein family, is an attractive target for cancer therapy. We investigated the effects of YM155, a small molecule inhibitor of survivin expression, on the radiosensitivity of human non-small cell lung cancer (NSCLC) cell lines and elucidated a relationship between the cellular localization of survivin and DNA double-strand break ...

Spontaneous and double-strand break (DSB)-induced allelic recombination in yeast was investigated in crosses between ura3 heteroalleles inactivated by an HO site and a +1 frameshift mutation, with flanking markers defining a 3.4-kbp interval. In some crosses, nine additional phenotypically silent RFLP mutations were present at approximately 100-bp intervals. Increasing heterology from 0.2 to 1%...

For a separated sequence Λ = {λk}k∈Z of real numbers there is a close link between the lower and upper densities D−(Λ), D(Λ) and the frame properties of the exponentials {ek}k∈Z: in fact, {ek}k∈Z is a frame for its closed linear span in L(−γ, γ) for any γ ∈]0, πD−(Λ)[∪]πD+(Λ),∞[. We consider a classical example presented already by Levinson [10] with D−(Λ) = D(Λ) = 1; in this case, the frame pr...

Rarely, do we think of cancer as “bacterial”, such that we are often told that “cancer is NOT contagious” Persistent bacterial infections cause persistent irritation of the host’s defense systems, which when ineffective in eradication of the infection, result in a multitude of self-destructive damages. This in some cases occurs to such severity that the resu...

Abstract Rather than relying on a potentially poor point estimate of coefficient break date when forecasting, this paper proposes averaging forecasts over sub-samples indicated by confidence interval or set for the date. Further, we examine whether explicit consideration possible variance and use two-step methodology improves forecast accuracy compared with using heteroskedasticity robust infer...

Lambda lifting transforms local function deenitions in functional programming languages into global ones to facilitate their eecient implementation. When considered as a source-to-source transformation for an ML-style typed language, all published algorithms for lambda lifting break typability. We break down two representative lambda lifting algorithms into four elementary transformation steps,...
