The goal of the DIRAC experiment at CERN (PS212) is to measure $\pi^+\pi^-$ atom lifetime with 10% precision. Such a measurement would yield precision 5% on value $S$-wave $\pi\pi$ scattering lengths combination $|a_0-a_2|$. Based part collected data we present first result lifetime, $\tau=[2.91 ^{+0.49}_{-0.62}]\times 10^{-15}$ s, and discuss major systematic errors. This corresponds $|a_0-a_2|=0.264 ^{+0.033}_{-0.020} m_{\pi}^{-1}$.
If neutrinoless double beta decay is discovered, the next natural step would be understanding lepton number violating physics responsible for it. Several alternatives exist beyond exchange of light neutrinos. Some these mechanisms can distinguished by measuring phase-space observables, namely opening angle $\cos\theta$ among two electrons, and electron energy spectra, $T_1$ $T_2$. In this work, we study statistical accuracy precision in kinematic observables a future xenon gas detector with...
We investigate the performance of Opticks, an NVIDIA OptiX API 7.5 GPU-accelerated photon propagation compared with a single-threaded Geant4 simulation. compare simulations using improved model NEXT-CRAB-0 gaseous time projection chamber. Performance results suggest that Opticks improves simulation speeds by between $58.47\pm{0.02}$ and $181.39\pm{0.28}$ times relative to CPU-only these vary different types GPU CPU. A detailed comparison shows number detected photons, along their...
The DIRAC experiment at CERN has achieved a sizeable production of $\pi^+\pi^-$ atoms and significantly improved the precision on its lifetime determination. From sample 21227 atomic pairs, 4% measurement S-wave $\pi\pi$ scattering length difference $|a_0-a_2| = (.0.2533^{+0.0080}_{-0.0078}|_\mathrm{stat}.{}^{+0.0078}_{-0.0073}|_\mathrm{syst})M_{\pi^+}^{-1}$ been attained, providing an important test Chiral Perturbation Theory.
Competent larvae of the black scallop Chlamys varia (L.) were treated with neurotransmitter gamma-amino-n-butyric acid (GABA), catecholamine epinephrine, and 3-isobutyl-1-methylxanthine (IBMX), at different concentrations times exposure, to test effects exposure compounds on larval settlement. After 24 h, maximum percentage settlement (>30%) was induced by 10−5 M epinephrine. 48 rate also achieved epinephrine (>54%). Exposure 10−6 GABA significantly higher than in control larvae. By...
The production of the flat oyster Ostrea edulis (L.) natural spat in Europe has decreased almost by 60% past ten years. Thus, importance hatcheries is evident. One critical steps hatchery broodstock conditioning, especially difficult autumn, when gonadal development resting period. Conditioning influence temperature, photoperiod and nutrition. In this work, effects two temperature three regimes on conditioning O. were studied for years stereological analyses registering number dates spawning...
Some species of the genus Pseudo-nitzschia produce toxin domoic acid, which causes amnesic shellfish poisoning (ASP). Given that bivalve mollusks are filter feeders, they can accumulate these toxins in their tissues. To elucidate transcriptional response queen scallop Aequipecten opercularis after exposure to acid-producing Pseudo-nitzschia, digestive gland transcriptome was de novo assembled using an Illumina HiSeq 2000 platform. Then, a differential gene expression analysis performed....
To optimize the conditioning procedure to obtain better larvae with lower production costs, Ruditapes decussatus broodstock was conditioned at different periods during year [October (C1), February (C2), and April (C3)] under two controlled temperature regimes: a constant (CT, 20°C) gradual increase in from ambient 20°C (GT). Samples (30 adult clams) were collected randomly every month control group each tank (three tanks for treatment). A section of gonad-visceral mass sampled gonadal...
Blooms of toxic microalgae and the accumulation their compounds in bivalve molluscs are a regular worldwide problem to both consumers producers. To select populations that accumulate less amount toxins is very important understand metabolism biotoxins. The study gene expression patterns by real-time quantitative polymerase chain reaction (RT-qPCR) may provide insights into genes involved detoxification metabolic pathways. One critical steps using RT-qPCR results have be normalized internal...
Some diatom species of the genus Pseudo-nitzschia produce toxin domoic acid. The depuration rate acid in Pecten maximus is very low; for this reason, king scallops generally contain high levels their tissues. A transcriptomic approach was used to identify genes differentially expressed P. digestive gland after injection differential expression analysis found 535 (226 up-regulated and 309 down-regulated). Protein–protein interaction networks obtained with were enriched gene ontology terms,...
The mussel Mytilus galloprovincialis is one of the most important aquaculture species in Europe. Its main production problem accumulation toxins during coastal blooms, which prevents commercialization. P-glycoprotein (ABCB1/MDR1/P-gp) part multixenobiotic resistance system aquatic organisms, and okadaic acid, DSP toxin, probably a substrate P-gp-mediated efflux. In this study, presence possible role P-gp acid detoxification process was studied M. galloprovincialis. We identified, cloned,...
A liquid isooctane (C8H18) filled ionization linear array for radiotherapy quality assurance has been designed, built and tested. The detector consists of 128 pixels, each them with an area 1.7 mm × a gap 0.5 mm. small pixel size makes the ideal high gradient beam profiles such as those present in intensity modulated radiation therapy (IMRT) radiosurgery. As read-out electronics we use X-ray Data Acquisition System Xchip developed by CCLRC. Studies concerning collection efficiency dependence...
