Dirty Liberals!

Many moral codes place a special emphasis on bodily purity, and manipulations that directly target bodily purity have been shown to influence a variety of moral judgments. Across two studies, we demonstrated that reminders of physical purity influence specific moral judgments regarding behaviors in the sexual domain as well as broad political attitudes. In Study 1, individuals in a public setti...

Dirty RF

Future wireless communications systems are expected to provide ever higher data rates. Still, devices have to be produced at reasonable cost in order to be affordable to customers. The widely known impairments – ”dirt effects” – in analog RF tend to aggravate as we go for the large transmission bandwidths and high carrier frequencies that usually come with an increased data throughput. To date,...

Achievable 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 ...

QUIC & 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...
