We report a highly sensitive means of measuring cellular dynamics with a novel interferometer that can measure motional phase changes. The system is based on a modified Michelson interferometer with a composite laser beam of 1550-nm low-coherence light and 775-nm CW light. The sample is prepared on a coverslip that is highly reflective at 775 nm. By(More)
Indirect immunofluorescence (IIF) on human epithelial (HEp-2) cells is considered as the gold standard screening method for the detection of antinuclear autoantibodies (ANA). However, in terms of automation and standardization, it has not been able to keep pace with most other analytical techniques used in diagnostic laboratories. Although there are already(More)
RATIONALE It has been postulated that cardiovascular reactivity to mental stress varies with tonic central sympathetic nervous system activity, but pharmacological evidence is missing. OBJECTIVE To test whether modulation of central sympathetic nervous system activity by alpha2-adrenergic agonism and antagonism affects cardiovascular reactivity to mental(More)
"Three-dimensional Bayesian geostatistical aquifer characterization at the Hanford 300 Area using tracer test data" (2012). US Department of Energy Publications. Paper 309. [1] Tracer tests performed under natural or forced gradient flow conditions can provide useful information for characterizing subsurface properties, through monitoring, modeling, and(More)
Traits are widely used to detect and explain responses of ecosystem processes to environmental changes. Various studies use trait data from databases, often providing one value per trait and species, neglecting intraspecific trait variability along spatio-temporal gradients. Handbooks for standardized trait measurements claim that traits should be measured(More)
Pollination is a crucial plant–animal interaction in ecosystems, and moths (Lepidoptera) are a widespread and species-rich group of flower visitors. In this article, plant and moth species connected via pollination interactions were identified from the literature, and information on the relevance of moth pollination in various ecosystems, including(More)
Prepulse inhibition of startle (PPI) represents an automatic mechanism that reflects sensorimotor gating and early attention processes. PPI neither is the consequence of conscious behavioral modulation nor does it depend on learning and conditioning. However, pairing of weak tones and aversive startle stimuli during PPI testing may induce associative(More)
