چکیده

We introduce a new metric for dynamic range of displays that closely corresponds with human perception in practical settings. The Number of Distinguishable Grays is a count of the visible luminance steps from the deepest black to the brightest white a display produces under known ambient conditions.

A Property of Recurring Series.

Wehavepi = 1,p2 = ,pl+p2 =1,whereasp = 2. Had the equations been written in the opposite order, we should have found pi = 2, P2 = 0, Pl + P2 = 2. This illustrates the fact that PI + + Pr, unlike the rank, is not an invariant. 1 Species is defined in the author's paper "Pfaffian Systems of Species One," Trans. Amer. Math.

The bromodomain protein LIN-49 and trithorax-related protein LIN-59 affect development and gene expression in Caenorhabditis elegans.

We have molecularly characterized the lin-49 and lin-59 genes in C. elegans, and found their products are related to Drosophila trithorax group (trx-G) proteins and other proteins implicated in chromatin remodelling. LIN-49 is structurally most similar to the human bromodomain protein BR140, and LIN-59 is most similar to the Drosophila trx-G protein ASH1. In C. elegans, lin-49 and lin-59 are re...

Defining the reference range for oxygen saturation for infants after birth.

OBJECTIVE The goal was to define reference ranges for pulse oxygen saturation (Spo(2)) values in the first 10 minutes after birth for infants who received no medical intervention in the delivery room. METHODS Infants were eligible if a member of the research team was available to record Spo(2) immediately after birth. Infants were excluded if they received supplemental oxygen or any type of a...

21 . 1 / G . Ward 21 . 1 : Invited Paper : The Hopeful Future of High Dynamic Range Imaging

This paper offers an overview of the challenges and opportunities presented by high dynamic range (HDR) imaging. We examine the length of the imaging pipeline, from creation and storage through image editing and viewing, and discuss how each stage is affected by a move to HDR.
