Abstract The Bluelink Ocean Data Assimilation System (BODAS) is an ensemble optimal interpolation system applied to a global ocean general‐circulation model with 10 km resolution around Australia. BODAS derives estimates of forecast‐error covariances (FECs) from stationary 72‐member intraseasonal anomalies. FECs are localized each observation reduce the negative effects sampling error and increase rank ensemble. have characteristics that reflect length‐scales anisotropy circulation in...
The decay energy spectrum for neutron unbound states in 24O (Z=8, N=16) has been observed the first time. resonance of lowest lying state, interpreted as 2+ level, at a above 600 keV. resulting excitation level 4.7 MeV, supplies strong evidence that is doubly magic nucleus. data also consistent with presence second excited state around 5.33 MeV which can be 1+ level.
Abstract. Analysis of the variability last 18 yr (1993–2012) a 32 run new near-global, eddy-resolving ocean general circulation model coupled with biogeochemistry is presented. Comparisons between modelled and observed mean sea level (MSL), mixed layer depth (MLD), anomaly (SLA), surface temperature (SST), {\\chla} indicate that realistic. We find some systematic errors in MLD, generally deeper than observations, which results {\\chla}, owing to strong biophysical coupling. evaluate several...
The neutron unbound ground state of (25)O (Z=8, N=17) was observed for the first time in a proton knockout reaction from (26)F beam. A single resonance found invariant mass spectrum corresponding to decay energy 770_+20(-10) keV with total width 172(30) keV. N=16 shell gap established be 4.86(13) MeV by difference between nu1s(1/2) and nu0d(3/2) orbitals. separation energies agree calculations universal sd model interaction. This interaction incorrectly predicts an (26)O that is bound...
We report on the first observation of dineutron emission in decay 16Be. A single-proton knockout reaction from a 53 MeV/u 17B beam was used to populate ground state 16Be is bound with respect one neutron and unbound two-neutron emission. The character evidenced by small angle between two neutrons. separation energy measured be 1.35(10) MeV, good agreement shell model calculations, using standard interactions for this mass region.
In this work, we have reviewed the Oslo method, which enables simultaneous extraction of level density and $\ensuremath{\gamma}$-ray transmission coefficient from a set particle-$\ensuremath{\gamma}$ coincidence data. Possible errors uncertainties been investigated. Typical data sets various mass regions as well simulated tested against assumptions behind analysis.

Purpose To determine normative diffusion values of the median nerve at several anatomic locations in healthy men and women variable age to compare these with those patients carpal tunnel syndrome. Materials Methods After ethics board approval written informed consent were obtained, 45 volunteers (30 women, 15 men) (10 five studied. Volunteers divided into three groups. Magnetic resonance (MR) neurography diffusion-tensor imaging (DTI) was performed all study participants 3.0 T by using a...
Evidence for the ground state of neutron-unbound nucleus 26O was observed first time in single proton-knockout reaction from a 82 MeV/u 27F beam. Neutrons were measured coincidence with 24O fragments. determined to be unbound by 150+50-150 keV observation low-energy neutrons. This result agrees recent shell model calculations based on microscopic two- and three-nucleon forces.
Ningaloo Niño refers to the episodic occurrence of anomalously warm ocean conditions along subtropical coast Western Australia (WA). typically develops in austral spring, peaks summer, and decays autumn, it often occurs conjunction with La Niña Pacific which promote poleward transport tropical waters by Leeuwin Current. Since late 1990s, there has been a marked increase Niño, is likely related recent swing negative phase Interdecadal Oscillation (IPO) enhanced El Niño–Southern variance since...
Marine heatwaves (MHWs), which are discrete extreme oceanic warming events, have important impacts on the marine ecosystem, fishery resources, and social economy. Previous studies based sea surface temperature suggest that MHWs in tropical western Pacific Ocean very weak. However, here we show observed by Tropical Atmosphere Ocean/Triangle Trans-Ocean Buoy Network buoys unexpectedly strong subsurface layer (50–300 m depth). The ensemble mean intensity of shows a peak about 5.2 °C at 150 m,...
The level density at low spin in the 161,162-Dy and 171,172-Yb nuclei has been extracted from primary gamma rays. nuclear heat capacity is deduced within framework of canonical ensemble. exhibits an S-formed shape as a function temperature, which interpreted fingerprint phase transition strongly correlated to uncorrelated phase. critical temperature for quenching pair correlations found Tc=0.50(4) MeV.
Radiative strength functions (RSFs) in $^{93\ensuremath{-}98}\mathrm{Mo}$ have been extracted using the $(^{3}\mathrm{He},\ensuremath{\alpha}\ensuremath{\gamma})$ and $(^{3}\mathrm{He},{^{3}\mathrm{He}}^{'}\ensuremath{\gamma})$ reactions. The RSFs are U shaped as function of \ensuremath{\gamma} energy with a minimum at around ${E}_{\ensuremath{\gamma}}=3 \mathrm{MeV}$. values increase neutron number because low-energy tail giant electric dipole resonance nuclear deformation. unexpected...
Rare isotope beams of neutron-deficient 106,108,110Sn from the fragmentation 124Xe were employed in an intermediate-energy Coulomb excitation experiment. The measured B(E2,0(1)(+)-->2(1)(+)) values for 108Sn and 110Sn results obtained 106Sn show that transition strengths these nuclei are larger than predicted by current state-of-the-art shell-model calculations. This discrepancy might be explained contributions protons within Z = 50 shell to structure low-energy excited states this region.
Abstract Ocean boundary currents are poorly represented in existing coupled climate models, partly because of their insufficient resolution to resolve narrow jets. Therefore, there is limited confidence the simulated response change by models. To address this issue, eddy-resolving Forecasting Australia Model (OFAM) was used, forced with bias-corrected output 2060s under Special Report on Emissions Scenarios (SRES) A1B from CSIRO Mark version 3.5 (Mk3.5) model, provide downscaled regional...
Abstract A striking feature of the South Indian Ocean circulation is presence eastward Countercurrent (SICC) that flows in a direction opposite to predicted by classical theories wind‐driven circulation. Several authors suggest SICC resembles subtropical countercurrents (STCCs) observed other oceans, which are defined as narrow jets on equatorward side gyres, where depth‐integrated flow westward. These associated with subsurface thermal fronts at thermocline depths wind relation. However,...
