Recovering High Dynamic Range Radiance Maps from Photographs

by Paul E. Debevec, Jitendra Malik
"... We present a method of recovering high dynamic range radiance maps from photographs taken with conventional imaging equipment. In our method, multiple photographs of the scene are taken with different amounts of exposure. Our algorithm uses these differently exposed photographs to recover the respon ..."
Abstract - Cited by 859 (15 self) - Add to MetaCart
. We demonstrate our method on images acquired with both photochemical and digital imaging processes. We discuss how this work is applicable in many areas of computer graphics involving digitized photographs, including image-based modeling, image compositing, and image processing. Lastly, we

A Multi-Algorithm, Multi-Timescale Method for Cell Simulation

by Kouichi Takahashi, Kazunari Kaizu, Bin Hu, Masaru Tomita , 2004
"... Motivation: Many important problems in cell biology require the dense nonlinear interactions between functional modules to be considered. The importance of computer simulation in understanding cellular processes is now widely accepted, and a variety of simulation algorithms useful for studying certa ..."

and different timescales. The utility of this simulation framework is demonstrated further with a ‘composite ’ heat-shock response model that combines the Gillespie–Gibson stochastic algorithm and deterministic differential equations. Dramatic improvements in performance were obtained without significant

Analysis of the mammalian heat-shock response. Inducible gene expression and heat-shock factor activity. Methods Mol. Biol

by Anu Mathew, Yanhong Shi, Caroline Jolly, Richard I. Morimoto , 2000
"... The evolutionarily conserved heat-shock response has been extensively studied as a model for transcriptional regulation. In eukaryotic cells, the regulation of heat-shock gene expression is mediated by a family of related proteins, the heat-shock transcription factors (HSFs) (1–8). Smaller eukaryote ..."

On the time relations of mental processes: An examination of systems of processes in cascade

by James L. Mcclelland - Psychological Review , 1979
"... This article examines the possibility that the components of an informationprocessing system all operate continuously, passing information from one to the next as it becomes available. A model called the cascade model is presented and it is shown to be compatible with the general form of the relatio ..."

of the relation between time and accuracy in speed-accuracy trade-off experiments. In the model, ex--perimentlLlmanipulations may have either or both of two effects on a processing level: They may alter the rate of response or the asymptotic quality pf the output. The effects of such manipulations on the output

Article Mathematical Modeling of the Heat-Shock Response in HeLa Cells

by Jeremy D Scheff , Jonathan D Stallings , Jaques Reifman , Vineet Rakesh
"... ABSTRACT The heat-shock response is a key factor in diverse stress scenarios, ranging from hyperthermia to protein folding diseases. However, the complex dynamics of this physiological response have eluded mathematical modeling efforts. Although several computational models have attempted to charac ..."

International Trade and Macroeconomic Dynamics with Heterogeneous Firms

by Fabio Ghironi , Marc J Melitz - Quarterly Journal of Economics , 2005
"... We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost in the domestic market and both fixed and per-unit export costs. Only relativ ..."

relatively more productive firms export. Exogenous shocks to aggregate productivity and entry or trade costs induce firms to enter and exit both their domestic and export markets, thus altering the composition of consumption baskets across countries over time. In a world of flexible prices, our model

The Heat-Shock Response: Its Variation, Regulation and Ecological Importance in

by Intertidal Gastropods (genus Tegula, Lars Tomanek
"... SYNOPSIS. The enhanced synthesis of heat-shock proteins (hsps), called the heat-shock (or stress) response, is activated when environmental stress denatures proteins. Hsp synthesis is activated at the upper temperatures of an organism’s thermal range and is therefore thought to be critical for enhan ..."

OPTIMAL PERFORMANCE OF THE HEAT-SHOCK GENE REGULATORY NETWORK 1

by Hana El Samad, M. Khammash, Chris Homescu, Linda Petzold
"... Abstract: In this work, we study the optimality principles in the heat shock response, a cellular response of utmost physiological importance. The heat shock response refers to the mechanism by which organisms react to a sudden increase in the ambient temperature. The consequence of such an unmediat ..."

Thermally Induced Injury and Heat-Shock Protein Expression in Cells and Tissues

by Marissa Nichole Rylander, A Yusheng Feng, B Jon Bass, B, Kenneth R. Dillera
"... ABSTRACT: Heat-shock proteins (HSPs) are critical components of a cell’s de-fense mechanism against injury associated with adverse stresses. Initiating in-sults, such as elevated or depressed temperature, diminished oxygen, and pressure, increase HSP expression and can protect cells against subseque ..."
