Ear candling is an alternative medicine practice alleged to enhance general health by putting an end of a hollow candle in the ear canal and lighting up the other end of it. It also is advertised for cerumen and debris (bacteria and fungi) removal. Ear candling is claimed to create negative pressure for drawing cerumen from the ear and to benefit the ears in many ways. It is however not free o...
متن کاملQUIC & DIRTY: A Quadratic Approximation Approach for Dirty Statistical Models
In this paper, we develop a family of algorithms for optimizing “superpositionstructured” or “dirty” statistical estimators for high-dimensional problems involving the minimization of the sum of a smooth loss function with a hybrid regularization. Most of the current approaches are first-order methods, including proximal gradient or Alternating Direction Method of Multipliers (ADMM). We propose...
متن کاملAchievable Rate Regions for Dirty Tape Channels and "Joint Writing on Dirty Paper and Dirty Tape"
We consider the Gaussian Dirty Tape Channel (DTC) YY = XX + SS + ZZ , where SS is an additive Gaussian interference known causally to the transmitter. The general expression mmmmmmPPUU,ff(∙),XX=ff(UU,SS) II(UU;YY) is presented for the capacity of this channel. For linear assignment to ff(∙) , i.e. XX = UU− ββSS , this expression leads to the compensation strategy proposed previously by Willems ...
متن کاملHow Dirty are "Quick and Dirty" Methods of Project Appraisal?
Routine "quick-and-dirty" (QD) methods of project appraisal can be so dirty in guiding project selection as to wipe out the net social gains from public investment. A common QD method for estimating benefits from irrigation investments is tested using data for Viet Nam. The results are compared to impacts assessed through econometric modelling of marginal returns that allows for household and a...
متن کاملA dirty word or a dirty world?: Attribute framing, political affiliation, and query theory.
We explored the effect of attribute framing on choice, labeling charges for environmental costs as either an earmarked tax or an offset. Eight hundred ninety-eight Americans chose between otherwise identical products or services, where one option included a surcharge for emitted carbon dioxide. The cost framing changed preferences for self-identified Republicans and Independents, but did not af...
