OBJECTIVES Local recurrence of rectal cancer reduces quality of life and survival. A multi-factorial linear logistic model was used to analyse risk factors for local recurrence in rectal cancer in patients not receiving preoperative chemo-radiation. METHODS A case-control study of patients with rectal cancer having surgery with curative intent, between 1996 and 2008. Eighteen putative risk fa...

Lawrence B. Holder and Diane J. Cook University of Texas at Arlington Box 19015, Arlington, TX 76019-0015 Email: fholder,[email protected] Abstract Most approaches to knowledge discovery concentrate on either an attribute-value representation or a structural data representation. The discovery systems for these two representations are typically di erent, and their integration is non-trivial. We ...

An exclusion particle model is considered as a highly simplified model of a limit order market. Its price behavior reproduces the well known crossover from over-diffusion (Hurst exponent H > 1/2) to diffusion (H = 1/2) when the time horizon is increased, provided that orders are allowed to be canceled. For early times a mapping to the totally asymmetric exclusion process yields the exact result...

A quality perspective in data resource management is critical. Because users have different criteria for determining the quality of data, we propose tagging data at the cell level with quality indicators, which are objective characteristics of the data and its manufacturing process. Based on these indicators, the user may assess the data's quality for the intended application. This paper invest...

High-quality, diverse, and photorealistic images can now be generated by unconditional GANs (e.g., StyleGAN). However, limited options exist to control the generation process using (semantic) attributes, while still preserving quality of output. Further, due entangled nature GAN latent space, performing edits along one attribute easily result in unwanted changes other attributes. In this paper,...
