Analisis Faktor-faktor yang Mempengaruhi Kreativitas Akuntan
This study aims to examine the influence of internal factors for the creativity accountans. Accounting is considered as the science is far from creativity. This causes an accountant is prevented from being creative possibilities. Accountants will be closed opportunities and the chance to be creative. This study examined the influence of ethics to the creativity accountant by Bryant, et al (2011) and Nurcahyo (2012). Ethics is measured using the dimensions of idealism and relativism. In addition, this study also examines the effect of job tenure, gender and intellectual of the creativity accountant.The population of this study is the auditor who works in the firm in the city of Semarang. The sample was an auditor who works in the firm in the city of Semarang with sampling techniques through sampling covinience. Data were collected through questionnaires and analyzed using multiple regressions.The results showed that the job tenure and gender had no effect on creativity accountant. In addition, intellectual and relativism significantly positive effect on creativity accountant. Idealism significantly negative effect on creativity accountant
Correlations and Pair Formation in a Repulsively Interacting Fermi Gas
A degenerate Fermi gas is rapidly quenched into the regime of strong
effective repulsion near a Feshbach resonance. The spin fluctuations are
monitored using speckle imaging and, contrary to several theoretical
predictions, the samples remain in the paramagnetic phase for arbitrarily large
scattering length. Over a wide range of interaction strengths a rapid decay
into bound pairs is observed over times on the order of 10\hbar/E_F, preventing
the study of equilibrium phases of strongly repulsive fermions. Our work
suggests that a Fermi gas with strong short-range repulsive interactions does
not undergo a ferromagnetic phase transition
Evaluating the accuracy of diffusion MRI models in white matter
Models of diffusion MRI within a voxel are useful for making inferences about
the properties of the tissue and inferring fiber orientation distribution used
by tractography algorithms. A useful model must fit the data accurately.
However, evaluations of model-accuracy of some of the models that are commonly
used in analyzing human white matter have not been published before. Here, we
evaluate model-accuracy of the two main classes of diffusion MRI models. The
diffusion tensor model (DTM) summarizes diffusion as a 3-dimensional Gaussian
distribution. Sparse fascicle models (SFM) summarize the signal as a linear sum
of signals originating from a collection of fascicles oriented in different
directions. We use cross-validation to assess model-accuracy at different
gradient amplitudes (b-values) throughout the white matter. Specifically, we
fit each model to all the white matter voxels in one data set and then use the
model to predict a second, independent data set. This is the first evaluation
of model-accuracy of these models. In most of the white matter the DTM predicts
the data more accurately than test-retest reliability; SFM model-accuracy is
higher than test-retest reliability and also higher than the DTM, particularly
for measurements with (a) a b-value above 1000 in locations containing fiber
crossings, and (b) in the regions of the brain surrounding the optic
radiations. The SFM also has better parameter-validity: it more accurately
estimates the fiber orientation distribution function (fODF) in each voxel,
which is useful for fiber tracking

Mouse Ooplasm Confers Context-Specific Reprogramming Capacity
Enucleated oocytes have the remarkable ability to reprogram somatic nuclei back to totipotency. Here we investigate genome-scale DNA methylation patterns after nuclear transfer and compare them to the dynamics at fertilization. We identify specific targets for DNA demethylation after nuclear transfer such as germ-line associated promoters, as well as unique limitations that include certain repetitive element classes.Stem Cell and Regenerative Biolog
Suppression of Density Fluctuations in a Quantum Degenerate Fermi Gas
We study density profiles of an ideal Fermi gas and observe Pauli suppression
of density fluctuations (atom shot noise) for cold clouds deep in the quantum
degenerate regime. Strong suppression is observed for probe volumes containing
more than 10,000 atoms. Measuring the level of suppression provides sensitive
thermometry at low temperatures. After this method of sensitive noise
measurements has been validated with an ideal Fermi gas, it can now be applied
to characterize phase transitions in strongly correlated many-body systems.Comment: minor edit: fixed technical problem with arxiv's processing of .eps

Tensor interaction constraints from beta decay recoil spin asymmetry of trapped atoms
We have measured the angular distribution of recoiling daughter nuclei
emitted from the Gamow-Teller decay of spin-polarized Rb. The
asymmetry of this distribution vanishes to lowest order in the Standard Model
(SM) in pure Gamow-Teller decays, producing an observable very sensitive to new
interactions. We measure the non-SM contribution to the asymmetry to be
= 0.015 0.029 (stat) 0.019 (syst), consistent with the SM
prediction. We constrain higher-order SM corrections using the measured
momentum dependence of the asymmetry, and their remaining uncertainty dominates
the systematic error. Future progress in determining the weak magnetism term
theoretically or experimentally would reduce the final errors. We describe the
resulting constraints on fundamental 4-Fermi tensor interactions.Comment: 11 pages, 13 figures; v2 published in Phys. Rev. C, with referee
