The study of dream activity and its relation to physiological variables during sleep necessitates a reliable method of determining with precision when dreaming occurs. This knowledge, in the final analysis, always depends upon the subjective report of the dreamer, but becomes relatively objective if such reports can be significantly related to some physiological phenomena which in turn can be m...

Dissolved organic matter (DOM) is a complex mixture of organic compounds, ubiquitous in marine and freshwater systems. Fluorescence spectroscopy, by means of Excitation-Emission Matrices (EEM), has become an indispensable tool to study DOM sources, transport and fate in aquatic ecosystems. However the statistical treatment of large and heterogeneous EEM data sets still represents an important c...

Supercooled liquids are proposed to be dynamically heterogeneous, with regions exhibiting relaxation time scales that vary in space and time. Measurement of the distribution of such time scales could be an important test of various proposed theories of vitrification. Single molecule fluorescence experiments attempt to uncover this distribution, typically by embedding single molecule probes into...

In this study, a fluorescence approach was used to evaluate the production of soluble microbial products (SMP) in aerobic granular sludge system under the stress of 2,4-dichlorophenol (2,4-DCP). A combined use of three-dimension excitation emission matrix fluorescence spectroscopy (3D-EEM), Parallel factor analysis (PARAFAC), synchronous fluorescence and two-dimensional correlation spectroscopy...

Typical cleft hand is a rare disorder usually inherited in an autosomal-dominant manner. We report a case of bilateral typical cleft hand in a 6-year-old male. There was no positive family history of such presentation, and no systemic manifestations were associated with this entity. Preanesthetic evaluation revealed no systemic or airway challenges and parents were counseled for routine surgica...

The hierarchy ∆matm ≫ ∆m⊙ and the large θ23 mixing angle, as suggested by neutrino oscillation experiments, can be accounted for by a variety of lepton flavour models. A dichotomy emerges: i) Models were all neutrino masses are bounded by matm ≡ (∆matm) 1 2 ≈ 0.03eV ; ii) Models of quasi-degenerate neutrinos. It is shown how these different patterns of neutrino masses may arise from different l...

INTRODUCTION In April and June 2012, two outbreaks of Campylobacter gastroenteritis were investigated in an Australian aged-care facility (ACF); a Campylobacter-positive puppy was identified as a potential source of infection. METHODS An expert panel was convened to assess transmission risk from the puppy to elderly residents and to guide further public health action. Criteria considered as p...

The observed inclusive decay of B–mesons into η′ + X is interpreted as the consequence of the gluonic decay of the b–quark into an s–quark. As a result of the QCD anomaly this decay proceeds partly as the decay b → s + η′, similar to b → s + J/ψ. The hadronic recoiling system is found to have a relatively large mass. Analogously one expects a decay of the type b→ s+ σ. The branching ratios for ...
