Abstract

Motivation: Recent genomic studies have confirmed that cancer is of utmost phenotypical complexity, varying greatly in terms of subtypes and evolutionary stages. When classifying cancer tissue samples, subnetwork marker approaches have proven to be superior over single gene marker approaches, most importantly in cross-platform evaluation schemes. However, prior subnetwork-based approaches do not explicitly address the great phenotypical complexity of cancer.

Results: We explicitly address this and employ density-constrained biclustering to compute subnetwork markers, which reflect pathways being dysregulated in many, but not necessarily all samples under consideration. In breast cancer we achieve substantial improvements over all cross-platform applicable approaches when predicting TP53 mutation status in a well-established non-cross-platform setting. In colon cancer, we raise prediction accuracy in the most difficult instances from 87% to 93% for cancer versus non−cancer and from 83% to (astonishing) 92%, for with versus without liver metastasis, in well-established cross-platform evaluation schemes.

Amazing Race

# Rocket Building
You construct a water-powered rocket, and the team that sends their rocket the furthest wins.

# Bridge building
The team have to get from one side of a beach or lawn to another, using only the pieces of wood provided. and without them or the wood touching the ground. Requires good planning and balance.

Confident people.

10 things you can do right now to improve your chances for a promotion
Beth Braccio Hering, Special to CareerBuilder

Hurzeler claims that confidence level is the first thing he notices when someone enters his office. He also claims that most confident people are faking it. "They are just as scared of the world as the next person, but they have learned to push that fear into the background so they can reach over their heads and pull themselves up. Confident people are willing to explore, to lead, to speak up, to try new things, to innovate, to fail and to get up off the ground and try again."

"Winners know who the players are in the company and throughout the whole industry. They work to understand it all so that someday they can run it all."
