Blum and Mitchell introduced a model of learning in (Blum & Mitchell, 1998) where each instance X is composed of two views (X1; X2) with X1 conditionally independent of X2 given the label of X . They showed that the target concept is learnable using X2 and the labels of a weak predictor f on X1 because the labels generated by f behave like the actual label corrupted by independent classificatio...

Permanent crops, such as olive groves, vineyards and fruit trees, are important in European agriculture because of their spatial and economic relevance. Agricultural geographical databases (AGDBs) are commonly used by public bodies to gain knowledge of the extension covered by these crops and to manage related agricultural subsidies and inspections. However, the updating of these databases is m...

Global transcriptome investigations often result in the detection of an enormous number of transcripts composed of non-co-linear sequence fragments. Such 'aberrant' transcript products may arise from post-transcriptional events or genetic rearrangements, or may otherwise be false positives (sequencing/alignment errors or in vitro artifacts). Moreover, post-transcriptionally non-co-linear ('PtNc...

BACKGROUND Measurement of the arterial carbon dioxide (P(a)CO(2)) is an established part of the monitoring of mechanically ventilated patients. Other ways to get information about carbon dioxide in the patient are measurement of end-tidal carbon dioxide (P(ET)CO(2)) and transcutaneous carbon dioxide (PTCCO2). Carbon dioxide in the blood and cerebral tissue has great influence on vasoactivity an...

Although multiple lines of evidence suggest that early adult life is very important in shaping the reproductive behavior of males, few studies have looked at the fitness consequences of the variation in reproductive behavior induced by differences in early life experience of males. Using a long term laboratory adapted population of Drosophila melanogaster Meigen (Diptera: Drosophilidae), early ...

We report vibrationally resolved photoelectron spectroscopy (PES) of Au(2)(CO)(n)(-) (n = 1-3), in combination with relativistic density functional theory (DFT) and ab initio calculations. The ground-state transition in the spectrum of Au(2)CO(-) is broad, containing vibrational structures both in the bending and in the CO stretching modes and suggesting a large structural change from Au(2)CO(-...

The coadsorption of D2O and CO on Rh(100) under ultrahigh vacuum has been investigated by using infrared reflection absorption spectroscopy. The results show that the presence of D2O induces partial displacement of the CO molecules from linear to bridged configurations. The resulting spectra are very similar to those observed at equivalent CO coverages in an electrochemical environment. The spe...

The Relationship of Regional Cerebrovascular CO, Reactivity to Blood Pressure and Regional Resting Flow • Cerebrovascular CO 2 reactivity (the change in cerebral blood flow per mm Hg change in Pa c02) is shown to be directly related to resting flow and inversely related to blood pressure for regional as well as for mean CBF data. Both regional and mean CO 2 reactivity therefore are proportional...

Cerebral vasomotor reactivity (CVMR) to changes in arterial carbon dioxide tension (P aCO 2) is assessed during steady-state or transient changes in P aCO 2. This study tested the following two hypotheses: (i) that CVMR during steady-state changes differs from that during transient changes in P aCO 2; and (ii) that CVMR during rebreathing-induced hypercapnia would be blunted when preceded by a ...
