The deontic square of oppositions describes relations between four deontic concepts: ban, permission, obligation, and release from obligation. It is argued that people use these relations not only when they interpret deontic social rules, but also when they reason from given rules. Data from several studies are presented that corroborate this argument.

Applications of elliptic curve cryptography to anonymity, privacy and censorship circumvention call for methods to represent uniformly random points on elliptic curves as uniformly random bit strings, so that, for example, ECC network traffic can masquerade as random traffic. At ACM CCS 2013, Bernstein et al. proposed an efficient approach, called “Elligator,” to solving this problem for arbitr...

Abstract: Sparse models for high-dimensional linear regression and machine learning have received substantial attention over the past two decades. Model selection, or determining which features or covariates are the best explanatory variables, is critical to the interpretability of a learned model. Much of the current literature assumes that covariates are only mildly correlated. However, in mo...

World Health Organization (WHO) last report about Iran's TB status shows rising trend of multidrug-resistant tuberculosis (MDR-TB) and HIV/TB. More than 95% illness and death of TB c...
