Analysis of thresholds for carcinogenicity

Toxicology Letters, 2004
Re-evaluations of large prominent studies, e.g. the ED01 study and N-nitrosodiethylamine, unequivocally have demonstrated that thresholds exist for carcinogenicity when the dose-response curves for animal studies done at high doses are calculated according to fundamental principles of chemistry.

Bayesian Arbitrage Threshold Analysis

1997
A Bayesian estimation procedure is developed for estimating multiple regime (multiple threshold) vector autoregressive models appropriate for deviations from financial arbitrage relationships. This approach has clear advantages over classical stepwise threshold autoregressive analysis.

Threshold analysis of cat conjugator

Optics Communications, 1997
Abstract Threshold analysis is performed for the cat conjugator, using our own method for the analysis of photorefractive optical circuits. An alternative road to obtaining threshold couplings and reflectivities of photorefractive oscillators is presented, leading to an improved understanding of their operation.

Bayesian analysis of threshold autoregressions

Communications in Statistics - Theory and Methods, 1992
A nonasymptotic Bayesian approach is developed for analysis of data from threshold autoregressive processes with two regimes. Using the conditional likelihood function, the marginal posterior distribution for each of the parameters is derived along with posterior means and variances.

Analysis of Experiments Measuring Threshold Taste

Biometrics, 1960
make a series of determinations, each of which involves a fixed number of liquid preparations-two in some experiments, three in others. Each group of preparations includes one or two beakers containing a given concentration of the test material while the remaining beakers contain only the solvent.

Analysis of fuzzy thresholding schemes

Pattern Recognition, 2000
Abstract Fuzzy thresholding schemes preserve the structural details embedded in the original gray distribution. In this paper, various fuzzy thresholding schemes are analysed in detail. Thresholding scheme based on fuzzy clustering has been extended to a possibilistic framework.

Threshold Analysis of Helicobacter pylori Therapy

PharmacoEconomics, 1998
Conflicting recommendations have been made on whom to treat with antibacterials to eradicate Helicobacter pylori. The present analysis aims to explain the basis of such discrepancies.The decision in favour of or against antibacterial therapy in patients with upper gastrointestinal symptoms is modelled as a threshold analysis.

Threshold dynamics : analysis and applications

2021
In this thesis, the threshold dynamics method is extended to a general interfacial energy and applied to topology optimization problem in fluids. The threshold dynamics was first proposed by Merriman, Bence and Osher to simulate mean curvature flow. It iterates in two steps, solving a heat equation and thresholding at a specific value.

Threshold Analysis for Absolute Productivity

2021
This chapter explains how an adaptation to the TI method can allow more direct comparisons across institutions through a calculation of absolute productivity. The tutorial builds from the case study used in Chaps. 4 and 5. It shows how a feature scaling technique can open the door for absolute productivity calculation and applies threshold analysis to ...

An Algorithm for Threshold Element Analysis

IEEE Transactions on Electronic Computers, 1965
A majority or threshold element is a device with a finite number of inputs and a single output. The output, F n is a Boolean function of the n binary valued variables (x 1 , x 2 , ..., x n ) applied to the inputs. The analysis of a threshold element is the determination of the output Boolean function, F n when the input variables and their ...
