In the field of heuristic search it is well-known that improving the quality of an admissible heuristic can significantly decrease the search effort required to find an optimal solution. Existing literature often assumes that admissible heuristics are consistent, implying that consistency is a desirable attribute. To the contrary, this paper shows that an inconsistent heuristic can be preferabl...

Self-awakening is the ability to awaken without external assistance at a predetermined time. Cross-sectional studies reported that people who self-awaken have sleep/wake habits different from those of people who use external means to wake from sleep. However, no longitudinal study has examined self-awakening. The present study investigated self- awakening, both habitual and inconsistent, compar...

From 1994 to 1997, the proportion of Neisseria gonorrhoeae highly resistant to ciprofloxacin (MIC >/=4 microg/mL) increased substantially among female sex workers (FSWs) in the Philippines. Among 1499 Filipina FSWs, we evaluated factors associated with gonococcal infection and with gonococcal antimicrobial resistance. By multivariate analysis, gonococcal infection was associated with sex with a...

We study some methods of subgradient projections for solving a convex feasibility problem with general (not necessarily hyperplanes or half-spaces) convex sets in the inconsistent case and propose a strategy that controls the relaxation parameters in a specific self-adapting manner. This strategy leaves enough user-flexibility but gives a mathematical guarantee for the algorithm's behavior in t...

Unintended pregnancy (UP) is a significant public health problem. The consistent use of effective contraception is the primary method to prevent UP. We examined the role of childhood sexual and physical violence and current interpersonal violence on the risk of unintended pregnancy among young, urban, sexually active women. In particular, we were interested in examining the role of childhood vi...
