Optimal Strong Rates of Convergence for a Space-Time Discretization of the Stochastic Allen-Cahn Equation with multiplicative noise

The stochastic Allen-Cahn equation with multiplicative noise involves the nonlinear drift operator ${\mathscr A}(x) = \Delta x - \bigl(\vert x\vert^2 -1\bigr)x$. We use the fact that ${\mathscr A}(x) = -{\mathcal J}^{\prime}(x)$ satisfies a weak monotonicity property to deduce uniform bounds in strong norms for solutions of the temporal, as well as of the spatio-temporal discretization of the problem. This weak monotonicity property then allows for the estimate $\underset{1 \leq j \leq J}\sup {\mathbb E}\bigl[ \Vert X_{t_j} - Y^j\Vert_{{\mathbb L}^2}^2\bigr] \leq C_{\delta}(k^{1-\delta} + h^2)$ for all small $\delta>0$, where $X$ is the strong variational solution of the stochastic Allen-Cahn equation, while $\big\{Y^j:0\le j\le J\big\}$ solves a structure preserving finite element based space-time discretization of the problem on a temporal mesh $\{ t_j;\, 1 \leq j \leq J\}$ of size $k>0$ which covers $[0,T]$

LOCUS OF CONTROL DAN KOMITMEN PROFESI DALAM PERILAKU ETIS MAHASISWA AKUNTANSI

Penyalahgunaan keahlian serta pelanggaran etika yang terjadi di profesi akuntansi mengakibatkan terjadinya skandal keuangan dalam membuat informasi akuntansi yang menyesatkan dan tidak benar untuk meraup keuntungan pribadi menimbulkan kerugian ekonomi masyarakat. Penelitian ini difokuskan pada aspek individual yang mempengaruhi sikap etis mahasiswa Program Studi Akuntansi yang ditunjukan dengan Locus Of Control serta komitmen profesi. Populasi yang digunakan dalam penelitian ini adalah mahasiswa Akuntansi Universitas Pembangunan Nasional “Veteran” Jawa Timur angkatan tahun 2010 berjumlah 184 mahasiswa. Pengambilan sampel menggunakan simple random sampling berjumlah 65 responden. Sumber data adalah data primer serta data sekunder. Teknik analisis yang digunakan adalah Partial Least Square (PLS). Berdasarkan hasil penelitian, nilai T-statistik dari variabel komitmen profesi sebesar 3.9948 lebih dari 1,96 yang artinya variabel komitmen profesi memberikan dampak positif dan signifikan terhadap perilaku etis. Nilai T-statistik dari variabel locus of control sebesar 1.4762 kurang dari 1,96 yang artinya variabel locus of control memberikan dampak negatif dan tidak signifikan terhadap perilaku etis. Sedangkan nilai T-statistik dari variabel locus of control sebesar 7.3147 lebih dari 1,96 yang artinya variabel locus of control memberikan dampak positif dan signifikan terhadap komitmen profesi. Kata Kunci : Locus of Control, Komitmen Profesi, dan Perilaku eti

The influence of religiosity, profit loss and sharing and corporate image toward consumer intentions of Muamalat bank financing

Purpose: This study aims to look at the influence of religiosity, profit and loss sharing and corporate image on consumer intentions of Muamalat bank financing in Madiun Design/methodology/approach: this study used a quantitative approach with a sample of 220 Muslim respondents in Madiun. And data analysis used smart PLS. Findings: The results of the analysis found that religiosity has a significant positive effect on consumer intentions, profit and loss sharing has a significant negative effect on customer intentions and corporate image does not affect consumers' intention of Muamalat bank financing in Madiun Practical implications: From the results will be as a marketing strategy to increase customers financing Muamalat banks, and find out the factors - factors that influence consumer intentions by looking at community religiosity and giving a low perception of profit and loss sharing of Muamalat bank financing in Madiun. Originality/value: The factor of religiosity can increase the consumer's intention of Muamalat bank financing in Madiun and the perception of profit and loss sharing can reduce the consumer's intention of Muamalat bank financing in Madiun.peer-reviewe

Continuous dependence estimate for a degenerate parabolic-hyperbolic equation with Levy noise

In this article, we are concerned with a multidimensional degenerate parabolic-hyperbolic equation driven by Levy processes. Using bounded variation (BV) estimates for vanishing viscosity approximations, we derive an explicit continuous dependence estimate on the nonlinearities of the entropy solutions under the assumption that Levy noise depends only on the solution. This result is used to show the error estimate for the stochastic vanishing viscosity method. In addition, we establish fractional BV estimate for vanishing viscosity approximations in case the noise coefficients depend on both the solution and spatial variable.Comment: 31 Pages. arXiv admin note: text overlap with arXiv:1502.0249

Effect of mycophenolate mofetil on the white blood cell count and the frequency of infection in systemic lupus erythematosus.

Leukopenia is a common manifestation of SLE. Addition of immunosuppressive therapy in a SLE patient who is already leukopenic is a clinical concern. It could worsen leukopenia, increase the risk of infection, or both. The aim of this study was to analyze the immediate effect of mycophenolate mofetil on the white blood cell count and the rate of infection in SLE patients. Two hundred and forty-four patients within the Hopkins Lupus Cohort who were newly started on mycophenolate mofetil were included in the study. The white blood cell count and interval infection history on the day mycophenolate mofetil was started were compared with the white blood cell count and interval infection history at the next visit. The study was based on 244 patients who began taking mycophenolate mofetil in the cohort. The study population included 47 % African Americans, 44 % Caucasians, and 9 % other ethnicities. There was a slight but not statistically significant increase in the white blood cell count (6.63 vs. 7.01), after starting mycophenolate mofetil. Patients with a baseline white blood cell count \u3c3000/mm(3) did have a statistically significant increase in the white blood cell count after starting mycophenolate mofetil (2.57 vs. 5.13, P = 0.0047). We also found a statistically significant increase in the risk of bacterial infection (but not viral infection) after starting mycophenolate mofetil (4 vs. 9 %, P = 0.0036). Leukopenia does not worsen with mycophenolate mofetil. However, mycophenolate mofetil appears to slightly increase the rate of bacterial (but not viral) infection

Meta-stable States in Quark-Gluon Plasma

We study the meta-stable states in high temperature phase of QCD characterised by nonzero expectation values for the imaginary part of the Polyakov loop. We consider $N_f= 2, 3$ dynamical staggered quarks, and carry out simulations at various values of the coupling $\beta$ to observe these states. In particular, we find the value of the coupling ($\beta_m$) above which the meta-stable states appear. The resulting value of $\beta_m$ corresponds to temperature $T_m \gtrsim 750$MeV for $N_f=2$.Comment: This version includes new simulations carried out on bigger lattices, particularly on $32^3 x 4$ and $32^3 x 6
