The Measurement of Receptor Signaling Bias
2015This chapter describes a method to quantify biased signaling effects of agonists; this approach can furnish a scale for medicinal chemists to optimize biased profiles. Biased ligands have different pharmacological properties on a molecular level (stabilization of different receptor active states) and thus can have different pharmacological profiles ...

Bounds on the Bias of Signal Parameter Estimators
Bell System Technical Journal, 1969Any estimator which is constrained to take values in a finite range is, in general, biased. Many times the bias is unknown; furthermore, in some cases the bias may become the main contributor to the mean square error of an estimator. This paper derives upper and lower bounds on the bias of a finite-range, signal parameter estimator.

The effect of nonlinear signal transformations on bias errors in elastography
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2000We have reported several artifacts in elastography (1991). These include mechanical artifacts, such as stress concentration, and signal processing artifacts, such as zebras, which are caused by bias errors incurred during the estimation of the peak of correlation functions using a curve-fitting method.

Bias analysis on return signal simulator of radar altimeter
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011The radar altimeter prelaunch calibration was commonly carried our by return signal simulator. The principles of return signal simulator, biases such as quadratic phase bias, amplitude and phase biases, delay bias were described in detail in this paper. In the last section the overall system bias on return signal simulator was calculated.

Ranging Bias of COMPASS Satellite Signals
2015Quantitative evaluation of signal quality of navigation satellites in orbit is one of the difficulties in satellite navigation signal quality monitoring research, so a quantitative evaluation method based on theoretic ranging bias is proposed. Based on Vernier sampling principle and a large diameter parabolic antenna is used for in-orbit satellite ...

Invisible overtures: Fears of rejection and the signal amplification bias.
Journal of Personality and Social Psychology, 2003Four studies demonstrated that fears of rejection prompt individuals to exhibit a signal amplification bias, whereby they perceive that their overtures communicate more romantic interest to potential partners than is actually the case. The link between rejection anxieties and the bias was evident regardless of whether fears of rejection were assessed ...
