Uniform W^{1,p} Estimates for Systems of Linear Elasticity in a Periodic Medium
Let be a family of elliptic systems of linear
elasticity with rapidly oscillating periodic coefficients. We obtain the
uniform estimate in a Lipschitz domain for solutions to the Dirichlet
problem, where . The ranges of 's
are sharp for or 3
Non-leptonic two-body weak decays of
We study the non-leptonic two-body weak decays of with () representing as the baryon (meson) states. Based
on the flavor symmetry, we can describe most of the data reexamined by
the BESIII Collaboration with higher precisions. However, our result of is larger than the
current experimental limit of (90\% C.L.) by BESIII. In
addition, we find that , , and , which are accessible
to the BESIII experiments.Comment: 12 pages, 1 figure, revised version accepted by PL
Matter Power Spectra in Viable Gravity Models with Massive Neutrinos
We investigate the matter power spectra in the power law and exponential
types of viable theories along with massive neutrinos. The enhancement
of the matter power spectrum is found to be a generic feature in these models.
In particular, we show that in the former type, such as the Starobinsky model,
the spectrum is magnified much larger than the latter one, such as the
exponential model. A greater scale of the total neutrino mass, , is allowed in the viable models than that in the CDM
one. We obtain the constraints on the neutrino masses by using the CosmoMC
package with the modified MGCAMB. Explicitly, we get $\Sigma m_{\nu} < 0.451 \
(0.214)\ \mathrm{eV}\Lambda\Sigma m_{\nu} < 0.200\
\mathrm{eV}N_{\mathrm{eff}}\Sigma m_{\nu}N_{\mathrm{eff}} = 3.78^{+0.64}_{-0.84} (3.47^{+0.74}_{-0.60})\Sigma m_{\nu} = 0.533^{+0.254}_{-0.411}< 0.386) \ \mathrm{eV}$ at 95%
C.L. in the Starobinsky (exponential) model.Comment: 15 pages, 5 figures, updated version accepted by PL
Developing Web Services Using Workflow Model: An Inter-organizational Perspective
This paper discusses how a workflow model can be used in the design and development of web services composition. We particularly investigate the development of web services composition in an inter-organizational workflow environment. We discuss respectively how to design an inter-organizational workflow from scratch when there is no existing internal workflow, and how to make existing internal workflows work together in an inter-organizational workflow environment
