Phylogenetic Profiling: How Much Input Data Is Enough?

Phylogenetic Profiling: How Much Input Data Is Enough?

Phylogenetic profiling is a well-established approach for predicting gene function based on patterns of gene presence and absence across species. Much of the recent developments have focused on methodological improvements, but relatively little is known about the effect of input data size on the quality of predictions. In this work, we ask: how many genomes and functional annotations need to be...

How Much Haptic Surface Data Is Enough?

The Proton Pack is a portable visuo-haptic surface interaction recording device that will be used to collect a vast multimodal dataset, intended for robots to use as part of an approach to understanding the world around them. In order to collect a useful dataset, we want to pick a suitable interaction duration for each surface, noting the tradeoff between data collection resources and completen...

Escalation: How Much is Enough?

often the subject of fierce debate. Cost increases are determined by dynamic relationships between many factors, including acts of nature, interest rates, oil prices, global commodity markets, wars, wage rates, and the overall health of the economy, as well as supply and demand for the required goods or services. How much escalation is enough? Are the recent price increases temporary aberration...

How much REST is enough?

Recent papers published in Nature by Guardavaccaro et al. and Westbrook et al. describe a nexus of two masters of negative regulation of protein levels. Both of these studies establish that the transcriptional repressor REST/NRSF is regulated by the highly versatile ubiquitin protein ligase (E3) SCF(beta-TrCP), adding a new dimension to the relationship between the ubiquitin-proteasome system a...
