Color and Uncertainty: It is not always Black and White

submitted by: alexandertoet
To fully comprehend the meaning and impact of visualized data it is crucial that users are able to perceive and comprehend the inherent uncertainty of the data in a correct and intuitive way. Data uncertainty is frequently visualized through color mappings. Previous studies argued that color hue is not suitable for communicating uncertainty because most hue scales lack an intrinsic perceptual order. In this paper we examine the use of hue for communicating data uncertainty in more detail. We...

Progress in Color Nightvision

submitted by: alexandertoet
I present a sample based color transfer method that gives nightvision imagery a realistic color appearance. The method is specific for different types of materials in a scene and can easily be adapted for the intended operating theatre and the task at hand. Because of its simplicity the method is highly suitable for real-time implementations. In this presentation I will show some nighttime movies that have been registered with prototype camera systems that apply the new color mapping...

biosights: June 9, 2014 - Rab18 tilts the balance of ER structure

submitted by: JCB
The endoplasmic reticulum consists of peripheral tubular networks connected to sheet-like domains surrounding the nucleus. Gerondopoulos et al. reveal that the Rab3GAP complex, which is mutated in the neurodevelopmental disorder Warburg Micro Syndrome, is a guanine nucleotide exchange factor that activates the small GTPase Rab18 (also mutated in Warburg Micro Syndrome) to control the balance between ER tubules and sheets. This biosights episode presents the paper by Gerondopoulos et al. from...

biosights: May 12, 2014 - Phosphoinositides get cells in shape

submitted by: JCB
Early Drosophila embryos undergo 13 rounds of rapid nuclear division before enclosing each nucleus into an individual, membrane-bound cell. Reversi et al. describe how the phosphoinositides PI(4,5)P2 and PI(3,4,5)P3 control the resulting cell shapes by coordinating actomyosin contractility with plasma membrane expansion. This biosights episode presents the paper by Reversi et al. from the May 12, 2014, issue of The Journal of Cell Biology and includes an interview with senior author Stefano...

Проповедь Франциска Ассизского птицам. Смысл, который придавал ей сам Святой и восприятие ее современниками (на основе письменных источников XIII века и ранней иконографии этой проповеди XIII-XV веков).

biosights: April 14, 2014 - An actin lever flattens out the cell

submitted by: JCB
The lamella is a broad, flat region that forms at the front of migrating cells and adheres to the underlying substrate. Burnette et al. reveal that cells flatten out the lamella by mechanically coupling a contractile actomyosin network at the dorsal surface to ventral cell adhesions. This biosights episode presents the paper by Burnette et al. from the April 14, 2014, issue of The Journal of Cell Biology and includes an interview with authors Dylan Burnette (Vanderbilt University School of...
