This paper aims at obtaining performance limitations of state estimation in terms of variance minimization (minimum variance estimation and filtering) using information theory. Two new notions, negentropy rate and Gaussianity-whiteness measure (joint Shannon-Wiener entropy), are proposed to facilitate the analysis. Topics such as Gaussianing-whitening filter (the maximum Gaussianity-whiteness m...

This article describes a project designed to change the climate of whiteness in academic nursing. Using an emancipatory, antiracist perspective from whiteness studies, we describe a project that helped faculty and staff to work together to challenge and begin to change the status quo of unnamed white privilege and racial injustice in nursing education.

Fluorescent Whitening Agents (FWA), dyes and pigmented inks are used extensively in the paper industry to enhance the appearance and optical performance of coated and uncoated papers. There are several different systems in use for the description and specification of color and optical properties of paper, using colorimeters, spectrophotometers and brightness meters. CIE and TAPPI are the most c...

In order to improve the whiteness of fly ash, the particles were coated by in-situ precipitation of calcium carbonate. After different mass ratios of calcium oxide to fly ash were mixed into water, a certain amount of carbon dioxide was bubbled into the mixture to form a precipitated calcium carbonate deposit on the surface of fly ash. With the help of scanning electron microscopy (SEM), the pr...

A father recounts a transformative journey of love, loss, and learning as his son developed and eventually died of a fungal infection that occurred during a period of immunocompromise after a bone marrow transplantation to treat hypodiploid leukemia. He then thanks the many physicians, researchers, family members, and friends who came together to memorialize his son and create knowledge, hope, ...

The world was warm and white when I was horn: Beyond the windowpane the world was white, A glaring whiteness in a leaded frame, Yet warm as in the hearth and heart of light, Although the whiteness was almost and was bone In midnight's still paralysis, nevertheless The world was warm and hope was infinite, All things would come, fulfilled, all things would be known All things would be enjoyed, f...

This paper draws on critical race theory to analyse testimonies from students that help explain why minoritised ethnic communities studying geography, planning, geology and environmental sciences in the UK, have a lesser chance of being awarded ‘good’ degree (i.e. an upper second- or first-class), comparison White British people. There are very low levels diversity across these subject areas. W...

Configuring whiteness as contagion, Birdie Lee, the narrator of Danzy Senna’s Caucasia, connects assimilation to illness and disease. Separated from her African American activist father, Birdie Lee and her blue-blooded mother flee from the law in a racialized and radicalized 1970s Boston. Eventually, the two take up residence in New Hampshire, where Birdie passes as "Jesse"and for white. This a...
