Screening for Hepatocellular Carcinoma to Improve Cancer-Related Mortality: Looking Behind When We Should Be Looking Ahead

Looking at Full Looking Ahead

Haralick and Elliott's full looking ahead algorithm [4] was presented in the same article as forward checking, but is not as commonly used. We give experimental results which indicate that on some types of constraint satisfaction problems, full looking ahead outperforms forward checking. We also present three new looking ahead algorithms, all variations on full looking ahead, which were designe...

Looking Ahead?

Human and nonhuman primates are not mentally constrained to the present. They can remember the past and—at least to an extent—anticipate the future. Anticipation of the future ranges from long-term prospection such as planning for retirement to more short-term future-oriented cognition such as planning a route through a maze. Here we tested a great ape species (chimpanzees), an Old World monkey...

Should we be screening for ovarian cancer?

Ovarian cancer carries the worst prognosis of all gynaecological cancers, with an overall five-year survival rate of around 30-40 percent. For women diagnosed with early-stage disease the five-year survival rate is over 80 percent1. Majority of the ovarian cancers present in advanced stages due to vague symptoms. Advanced stage disease carries a poor fiveyear survival rate of around 15 percent....
