Traditional question answering systems typically employ a single pipeline architecture, consisting roughly of three components: question analysis, search, and answer selection (see e.g., (Clarke et al., 2001a; Hovy et al., 2000; Moldovan et al., 2000; Prager et al., 2000)). The knowledge sources utilized by these systems to date primarily focus on the corpus from which answers are to be retriev...

duced with a single species, Asaia bogorensis Yamada et al. 2000 in the family Acetobacteraceae Gillis and De Ley 1980 (Yamada et al., 2000). Since the second and the third species described were Asaia siamensis Katsura et al. 2001 and Asaia krungthepensis Yukphan et al. 2004, three species are in total reported (Katsura et al., 2001; Yamada et al., 2000; Yukphan et al., 2004c). The species ass...

Predictions of chlorophyll content (chla+b) or any other canopy biophysical parameter from airborne or satellite canopy reflectance are generally carried out through four different methodologies: i) directly studying the statistical relationships between ground-measured biochemical data and canopy-measured reflectance (Johnson et al., 1994; Matson et al., 1994); ii) applying the leaf-level rela...

HIV-1 RT and protease sequencing and drug susceptibility testing have been done in research settings for more than ten years to elucidate the genetic mechanisms of resistance to antiretroviral drugs. Retrospective studies have shown that the presence of drug resistance before starting a new drug regimen is an independent predictor of virologic response to that regimen (DeGruttola et al., 2000; ...

In this paper we critique two recent studies that have been claimed to disprove the Out of Africa hypothesis for modern human origins (Hawks et al., 2000; Wolpoff et al., 2001). We show that the test prediction employed by Hawks et al. (2000) and Wolpff et al. (2001) is not relevant to many versions of the Out of Africa hypothesis, and that the key specimens they used are problematic in terms o...

As the world economy and population grow in the twenty-first century, atmospheric concentrations of CO 2 and other greenhouse gases are likely to continue to rise (Naki enovi and Swart 2000). Credible projections of future climate changes induced by these increases have many practical applications (e.g., for climate impact assessments and to guide future emissions controls). Most previous simul...

Plants as sessile organisms have evolved a great deal of developmental plasticity to optimally respond to their immediate environment. Because light is one of the most important cues for plant growth, mechanisms to respond to light conditions are highly elaborated. In particular, the transition from darkgrown (skotomorphogenic) to light-grown (photomorphogenic) development (Fig. 1) in Arabidops...

The success of assisted reproduction, although gradually increasing over the years, is still less than satisfactory. Many couples have benefited from this treatment; many have also been left frustrated following multiple failed attempts (Bulent Urman et al. 2005). Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...
