We previously found that dopamine signaling modulates the sensitivity of wild-type C. elegans to the aversive odorant 1-octanol. C. elegans lacking the CAT-2 tyrosine hydroxylase enzyme, which is required for dopamine biosynthesis, are hypersensitive in their behavioral avoidance of dilute concentrations of octanol. Dopamine can also modulate the context-dependent response of C. elegans lacking...

Although phosphorus limitation is common in freshwaters and bacteria are known to use dissolved organic phosphorus (DOP), little is known about how efficiently DOP compounds are taken up by individual bacterial taxa. Here, we assessed bacterial uptake of three model DOP substrates in two mountain lakes and examined whether DOP uptake followed concentration-dependent patterns. We determined bulk...

Quickly finding low-energy multicast routings is vital for a wireless system’s energy efficiency. Therefore, key aspects for heuristics for the minimum energy multicast problem (MEMP) are time complexity (measured in the numbers |V | and |A| of networking devices and their possible power assignments, respectively) and deviation from optimum. Following a center-oriented approach, we develop the ...

Method: The study was carried out in three phase. Phase I: V-DOP developed by Konnai et al., 2010 (in Kannada & English for Indian population) was translated in Tamil and verified for content validity. Phase II: English and Tamil version of V-DOP was administered on forty eight subjects for validation. Phase III: Correlating scores from DSI and V-DOP was done on fifty subjects with voice concer...

We investigated if any change in spatial resolution of comparative genomic hybridization analysis could be detected when using DNA amplified by degenerate oligonucleotide primed PCR (DOP-PCR) as opposed to the use of unamplified DNA. Five DNA samples from B-cell leukemias with small 11q deletions were amplified by DOP-PCR and analysed by means of high resolution comparative genomic hybridizatio...

We address precision of estimation of the degree of polarization (DOP) from the orthogonal state contrast image (OSCI) in the presence of both signal-dependent Poisson noise due to useful signal, and additive Poisson noise due to dark current and / or background light. We determine the Cramer Rao Lower Bound and deduce from it figures of merit for DOP estimation. In particular, we show that the...

The Data-Oriented Parsing Model (DOP, [1]; [2]) has been presented as a promising paradigm for NLP. It has also been used as a basis for Machine Translation (MT) — Data-Oriented TVanslation (DOT, [9]). Lexical Functional Grammar (LFG, [5]) has also been used for MT ([6]). LFG has recently been allied to DOP to produce a new LFG-DOP model ([3]) which improves the robustness of LFG. We summarize ...

The degree of polarization (DOP) of laser-speckle fields, where the speckles were generated by a polarized laser beam incident upon two kinds of samples: ground glass and wax, was investigated within a single coherence area as well as over multiple coherence areas. For the surface-scattering ground glass, the incident polarization state was preserved in the speckle field, and hence the DOP rema...

Cellularisation of the Drosophila syncytial blastoderm embryo into the polarised blastoderm epithelium provides an excellent model with which to determine how cortical plasma membrane asymmetry is generated during development. Many components of the molecular machinerydrivingcellularisationhavebeen identified, but cell signalling events acting at the onset of membrane asymmetry are poorly under...
