New reals: Can live with them, can live without them

Judah and Shelah [3] proved that countable support iterations of proper forcings preserve the ω-bounding property (see 2.2 here). In his book Proper and Improper Forcing [8, XVIII §3] Shelah gave several cases of general preservation theorems for proper countable support iterations (the proofs tend to be hard to digest, though). In this paper we deal with “Case A”. A simplified version of this ...

Antidepressants: can't live with them, can't live without them.

A new wave of meta-analyses suggests that antidepressants are no better than placebo for major depressive disorder (MDD), and therefore, antidepressants not only don't work, but even worse, they harm patients because of the risk of adverse effects.

Stop-smoking medications: who uses them, who misuses them, and who is misinformed about them?

The data for this paper came from a nationally representative, random-digit-dialed telephone survey of 1,046 adults (18 years of age and older) current cigarette smokers conducted between May and September 2001. Respondents were que...

Counting Circles Without Computing Them

In this paper we engineer a fast algorithm to count the number of triangles defined by three lines out of a set of n lines whose circumcircle contains the origin. The trick is not to compute any triangles or circles. 1998 ACM Subject Classification F.2.2 Nonnumerical Algorithms and Problems
